Description

  The present invention relates to a vehicle display device used in an automobile.

  In recent years, interest in environmental issues has increased, and automobiles are required to travel in an ecological and ecological manner. As one method for realizing this ecological traveling, a hybrid electric vehicle (hybrid vehicle) that travels using both an electric motor that consumes electric power and an engine that consumes fuel has been put into practical use.

  In a hybrid vehicle, an electric motor is used at the time of starting, an engine and an electric motor are used in combination at the time of acceleration, and surplus power is charged by operating the electric motor while running on the engine at a constant running. And at the time of deceleration, it charges by regenerative power generation with an electric motor. In this way, the electric motor is skillfully used in the driving conditions that the engine is not good at, and when the engine is operated, it is operated efficiently and surplus driving force is used for charging.

  For this reason, the traveling of the hybrid vehicle is eco-friendly compared with the traveling of the automobile that travels only by the engine.

  An instantaneous fuel consumption meter is used as a display device that displays whether or not the hybrid vehicle travels ecologically. The instantaneous fuel consumption meter is a meter that displays the instantaneous fuel consumption (km / L) calculated based on the travel distance (kilometer, km) and fuel consumption (liter, L) of the hybrid vehicle. When the instantaneous fuel consumption meter displays high fuel consumption, the driver recognizes that the traveling of the hybrid vehicle is ecological traveling.

  The instantaneous fuel consumption meter recognizes that the vehicle is eco-friendly when displaying high fuel efficiency, and recognizes that the vehicle is not eco-friendly when displaying low fuel consumption. That is, the instantaneous fuel consumption meter only qualitatively recognizes whether or not the vehicle is eco-friendly and cannot quantitatively display eco-friendly driving.

  Since the instantaneous fuel consumption is calculated from the past travel distance of about 200 milliseconds (about 0.2 seconds) and the fuel consumption, the instantaneous fuel consumption meter qualitatively determines whether or not the current travel is eco-friendly. Can be recognized. However, the instantaneous fuel consumption meter cannot make the driver recognize how much ecological driving has been performed.

  Moreover, since the instantaneous fuel consumption is not a numerical value of ecological traveling, it is not possible to display how much ecological traveling is accumulated even if the instantaneous fuel consumption is simply accumulated over time.

  This problem is not limited to hybrid vehicles. In other words, even in an automobile that runs on an engine that consumes fuel, instantaneous fuel consumption is not a numerical value of eco-driving, so how much eco-driving is accumulated even if instantaneous fuel economy is simply accumulated over time. I can't show what I'm doing.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a vehicular display device capable of displaying how much economy / ecological driving is being accumulated.

  In order to achieve the above object, the present invention employs the following technical means.

The display device for a vehicle according to claim 2 is a display device for a vehicle used for an automobile that is driven by an engine that consumes fuel, and the travel distance in terms of a unit amount by the fuel consumed in the vicinity of the present time is a determination value. It is determined whether or not the driving of the automobile is economy / ecological driving by determining whether or not the driving distance is greater than the determination value, and the driving is determined to be economy / ecological driving. A determination means for determining that the vehicle is an economy / ecological driving, and subtracting the determination value from the travel distance to determine the economy / ecological driving as an eco value, and the eco value And calculating means for calculating the accumulated value by time accumulation and display means for displaying the accumulated value. The predetermined value is erased when the accumulated value reaches the predetermined value, and accumulation is started again after the erasure, and the accumulation is performed by adding 1 to the number of times of erasure of the predetermined value. It is configured to calculate the started number of repetitions, and the display means is configured to display the number of repetitions.

In these configurations, digitizes the eco numerical values Economy ecological travel by subtracting the decision value from the travel distance of the unit quantity conversion by fuel consumption at present near Eco figures temporally cumulative cumulative Display the value. By quantifying economy and ecological driving, it becomes possible to accumulate economy and ecological driving over time, and by displaying the accumulated value of economy and ecological driving accumulated over time, economy and ecology are displayed. It is possible to display how many target runs are accumulated. Accordingly, it is possible to provide a display device for a vehicle that can display how much the economy / ecological driving is accumulated. In addition, in the configuration according to the first aspect, the accumulation is terminated when the accumulated value reaches the predetermined value. At this time, the display means displays the predetermined value. As a result, it is possible to display that the accumulated value of economy and ecological driving has reached the predetermined value, and before reaching the predetermined value, how much of the economy and ecological driving is accumulated relative to the predetermined value. Can be recognized. As a result, it is possible to provide a vehicular display device that can display in an easily recognizable manner how much economy / ecological driving is being performed. On the other hand, in the configuration of the second aspect, the predetermined value is erased after the accumulation is completed, the accumulation is started again after the erase, and the number of repetitions obtained by adding 1 to the number of erases of the predetermined value is displayed. Thereby, it can be displayed that the accumulated value of the economy and ecological driving has reached a predetermined value. The display means displays a predetermined value, and thereafter deletes the predetermined value to display the accumulated value. For this reason, before reaching the predetermined value, it is possible to repeatedly recognize how much the ecological and ecological traveling is accumulated with respect to the predetermined value. Moreover, since the number of repetitions obtained by adding 1 to the number of erasures of a predetermined value is displayed, this number of repetitions can be recognized.

According to a third aspect of the present invention, the vehicle display device is a hybrid electric vehicle that travels using both an electric motor that consumes electric power and an engine.

  Thereby, the above-mentioned effect can be acquired in the display apparatus for vehicles used for a hybrid electric vehicle.

According to a fourth aspect of the present invention, in the vehicle display device, the unit-equivalent travel distance by the fuel consumed in the vicinity of the current time is the unit-equivalent travel distance by the fuel consumed from the present time until a predetermined short time ago. Features.

  In this configuration, the eco-numerical value can be calculated more accurately because the travel distance in terms of unit amount based on the fuel consumed from the present time to a predetermined short time before is used for calculating the eco-value.

The display device for a vehicle according to claim 5 is characterized in that the travel distance in terms of a unit amount based on the fuel consumed from a current time to a predetermined short time before is an instantaneous fuel consumption.

  Thereby, the above-mentioned effect can be acquired using instantaneous fuel consumption.

The display means is configured to display the accumulated value in such a manner that the first display image is completed when the value reaches a predetermined value.

  In this configuration, the first display image that displays the accumulated value displays a predetermined value in a form in which the first display image is completed. Thereby, before reaching the predetermined value, it is possible to make it easier to recognize how much the ecological / ecological travel is accumulated with respect to the predetermined value.

According to a seventh aspect of the present invention, there is provided a vehicle display device comprising a notifying unit that notifies that the accumulated value has reached a predetermined value.

  Thereby, it can be made easier to recognize that the accumulated value has reached the predetermined value.

  In this configuration, in order to display eco-values, it is possible to display how much economy / ecological driving is accumulated, and in addition, how much economy / ecological driving is performed at any given time. Can be displayed.

The display device for a vehicle according to claim 9 is characterized in that the display means is configured to display the eco numerical value at a speed at which the second display image changes.

  In this configuration, since the eco value is displayed according to the speed at which the second display image changes, the display of the accumulated value obtained by accumulating the eco value can be recognized as the accumulation of the change speed of the second display image. As a result, the display of the cumulative value and the second display image, that is, the cumulative value and the ecological value, that is, “how much economy and ecological driving are accumulated” and “the economy “How much ecological driving is being performed” can be recognized in association with each other.

  Hereinafter, the case where the display device for vehicles according to the present invention is applied to a hybrid electric vehicle which is an automobile will be described with reference to the drawings.

  A hybrid vehicle 1 which is a hybrid electric vehicle has the main system configuration shown in FIG. At the start of the hybrid vehicle 1, the electric motor 2, which is an electric motor, operates by consuming electric power from the high voltage battery 3, and drives the drive wheels 8 through the transmission 7. The inverter 6 converts the DC power from the high voltage battery 3 into AC power and drives the electric motor 2.

  During acceleration, both the engine 4 and the electric motor 2 are operated to drive the drive wheels 8. The engine 4 operates by consuming fuel, and drives the drive wheels 8 via the power split mechanism 5 and the transmission 7. The electric motor 2 consumes electric power from the high-voltage battery 3 via the inverter 6 and drives the drive wheels 8 via the transmission 7.

  During constant travel, the engine 4 drives the drive wheels 8 via the transmission 7 and drives the electric motor 2 via the power split mechanism 5 to generate electric power with the surplus power. The AC power generated by the electric motor 2 is converted into DC power by the inverter 6 and charged to the high voltage battery 3. The power split mechanism 5 divides a driving force generated by the engine 4 by consuming fuel into a driving force for driving the driving wheels 8 and a driving force for driving the electric motor 2.

  Thus, in the hybrid vehicle 1, the electric motor 2 is skillfully used under the driving conditions that the engine 4 is not good at, and when the engine 4 is operating, it is operated efficiently and surplus driving force is used for charging.

  These controls are performed by a hybrid control device 9 (FIG. 3) composed of a microcomputer or the like. The high voltage battery 3 is a battery dedicated to a hybrid vehicle that drives the electric motor 2, and is a battery having a higher voltage than a battery for a general vehicle (not shown).

  A combination meter 10 that is a display device for a vehicle according to an embodiment of the present invention is configured as shown in FIG. 2A and is arranged in front of the driver's seat of the hybrid vehicle 1 to display various information related to the hybrid vehicle 1. . The combination meter 10 includes a speedometer 11 that displays the vehicle speed of the hybrid vehicle 1, a tachometer 12 that displays the number of revolutions of the engine 4, a warning indicator display unit 13 that displays various warning information and indicator information, and a display. And an eco display device 14 as means.

  On the outer periphery of the speedometer 11 and the tachometer 12, illumination rings 11a and 12a made of translucent acrylic resin and the like, and light emitting diodes 11b and 12b for illuminating the illumination rings 11a and 12a are arranged. The illumination rings 11a and 12a and the light emitting diodes 11b and 12b constitute notification means described later.

  The eco display device 14 includes a liquid crystal panel 140 and a light emitting diode (not shown) that illuminates and transmits the liquid crystal panel 140. As shown in FIG. 2B, the eco display device 14 (liquid crystal panel 140) displays a wheel-shaped second display image 14a, a first display image 14b, and a character “eco”. A first display image 14b is composed of ten bar-shaped unit images 14c extending to the left and right.

  In FIG. 3, on / off control of the light emitting diodes 11b, 12b, etc., drive control of the liquid crystal panel 140, and the like are performed by a meter control device 15 constituted by a microcomputer or the like. The hybrid control device 9 is configured to control the operation of the electric motor 2 and the engine 4 and to allow the meter control device 15 to input an information signal of instantaneous fuel consumption Fe (km / L). The instantaneous fuel consumption Fe (km / L) is calculated as a travel distance in terms of 1 liter, which is a unit amount converted from fuel consumed up to 0.2 seconds before a predetermined short time from the present time.

  The meter control device 15 includes a determination / calculation unit 15a having both a determination unit and a calculation unit, and a drive unit 15c that performs turning on / off control of the light emitting diodes 11b and 12b, drive control of the liquid crystal panel 140, and the like. . The determination / calculation means 15a includes a memory 15b including an electrically rewritable nonvolatile memory or a backup RAM (random access memory).

  Hereinafter, the control of the meter control device 15 and the display of the liquid crystal panel 140 with respect to the liquid crystal panel 140 will be described with reference to FIGS.

  Here, as described above, the hybrid vehicle 1 travels using the electric motor 2 that consumes electric power and the engine 4 that consumes fuel. Accordingly, it can be said that the traveling of the hybrid vehicle 1 is economy-ecological (eco-friendly) by the amount of traveling by the electric motor 2 that consumes electric power, as compared with the traveling of the automobile that travels only by the engine.

  However, in the hybrid vehicle 1, only the electric motor 2 is used, only the engine 4 is used, or both are used. For this reason, it is not appropriate to use the fuel consumption fuel consumption of the engine 4, that is, the instantaneous fuel consumption Fe (km / L) as an indicator of economy / ecology driving (eco driving).

  If the travel distance in terms of the unit amount of fuel becomes longer, it can be said that the travel of the hybrid vehicle 1 is ecological. Further, if the travel distance in terms of the unit amount of fuel is shortened, it can be said that the travel is in a bad state from an ecological point of view. Further, if the travel distance in terms of unit amount of fuel becomes a predetermined travel distance between them, it can be said that the travel is neither ecological nor bad.

  That is, this predetermined travel distance in the unit amount conversion of the fuel can be used as a determination value for determining whether or not the vehicle is eco-friendly, and the travel distance in terms of the unit amount of fuel exceeding the determination value can be used. It can be used as an eco-value that quantifies eco-friendly driving.

  Utilizing this concept, in FIG. 4, the judgment value is set to 50 km / L of the instantaneous fuel consumption Fe (km / L), and the judgment value of 50 km / L is subtracted from the instantaneous fuel consumption Fe (km / L). The target driving is digitized as an eco value Ev (km / L). Therefore, the cumulative value obtained by accumulating the eco value Ev (km / L) over time represents how much eco-driving is accumulated.

  The eco value Ev (km / L) is displayed as the rotational speed Vr (1 / second) of the second display image 14a, which is the speed of change of the second display image 14a, and the accumulated value of the eco value Ev (km / L) is displayed. The liquid crystal panel 140 is configured to calculate the rotation number R of the second display image 14a and display the rotation number R as the first display image 14b. FIG. 4 shows the relationship between the eco numerical value Ev (km / L) and the rotation speed Vr (1 / second).

  In FIG. 5, after the start of the control flow (S1), the determination / calculation means 15a inputs the instantaneous fuel consumption Fe (S2), and determines whether the instantaneous fuel consumption Fe is 50 or more (S3). If step 3 is Yes, it is determined that the vehicle is traveling ecologically, and the rotational speed Vr is calculated according to the equation of step 4 (S3). In step 5, the driving means 15c drives the liquid crystal panel 140 so that the second display image 14a is rotated and displayed at the rotational speed Vr in the direction of the broken line arrow P shown in FIG. 6 (S5).

  The determination / calculation means 15a calculates an increase ΔR in the number of revolutions per Δt of unit time according to the equation of Step 6 (S6), and calculates the number of revolutions R by adding the increment ΔR according to the equation of Step 7. (S7), it is determined whether or not the rotational speed R is 30,000 (S8). When step S8 is NO, it returns to step S2 and repeats steps S2-S8.

  If YES in step S8, the process advances to steps 9 and 10 to add and display unit images 14c (S9), and the number N of unit images 14c is calculated by adding 1 in accordance with the equation in step 10. (S10). 6A shows a case where the number N of unit images 14c is zero, and FIG. 6B shows a case where the number N of unit images 14c is three. Accordingly, in step 9, for example, from the state shown in FIG. 6A, the driving means 15c drives the liquid crystal panel 140 so that one unit image 14c is added and displayed.

  The memory 15b updates and stores the number N (S11), and the determination / calculation unit 15a determines whether the number N is 10 (S12). When step S12 is NO, the determination / calculation unit 15a sets the rotation speed R to zero (S13), returns to step S2, and repeats steps S2 to S12.

  When step S12 is YES, the light emitting diodes 11b and 12b are turned on, and this control flow is ended (S14). When step S12 is YES, the cumulative number of revolutions R is 300,000 of 30,000 × 10, indicating that the cumulative value of ecological driving has reached a predetermined value. That is, the number N of 10 unit images 14c corresponds to a predetermined value. When step S12 is YES, as shown in FIG.6 (d), a predetermined value is displayed in the aspect (state where the number N of unit images 14c is 10) of the 1st display image 14b being completed. At this time, the lighting rings 11a and 12a emit light by the light-emitting diodes 11b and 12b, so that it is possible to emphasize and display that the accumulated value of the ecological driving has reached a predetermined value.

  The control flow control program shown in FIG. 5 is stored in the memory unit 15b.

  As described above, according to the present embodiment, the eco-driving is converted into the eco-value Ev (km / L) by subtracting the judgment value 50 km / L from the instantaneous fuel consumption Fe (km / L). It is possible to accumulate traveling over time. In addition, by displaying the accumulated value of the ecological driving accumulated over time, it is possible to display how much the ecological driving is accumulated.

  Further, since the accumulation is terminated when the accumulated value reaches the predetermined value, it is possible to display that the accumulated value of the ecological driving has reached the predetermined value, and to reach the predetermined value before reaching the predetermined value. On the other hand, it is possible to recognize the relative proportion of eco-driving that is being performed.

  In addition, since the first display image 14b displays a predetermined value in a form in which the first display image 14b is completed, the economy / ecology is relative to the predetermined value at what relative ratio before reaching the predetermined value. It is possible to make it easier to recognize whether or not target driving is being accumulated.

  Further, since the eco numerical value Ev (km / L) is displayed on the second display image 14a, it is possible to display how much eco-driving is being performed at that time.

  Further, in order to display the eco value Ev (km / L) at the rotation speed (1 / second) of the second display image 14a, the first display image 14b that displays a cumulative value obtained by accumulating the eco value Ev (km / L). Can be recognized as the cumulative rotational speed (1 / second) of the second display image 14a. As a result, the first display image 14b and the second display image 14a, that is, the cumulative value and the eco numerical value Ev (km / L), that is, “how much is the economy / ecological driving accumulated? And “how much economy / ecological driving is performed at that time” can be recognized in association with each other.

(Modification)
In the first modified example shown in FIG. 7, the second display image 14a having a leaf shape instead of the wheel shape and the first display image 14b in which 20 unit images 14c are arranged in a ring shape are displayed. The display device 14 (liquid crystal panel 140) is configured. Further, the second display image 14a displays the eco numerical value Ev (km / L) by the falling speed in the direction of the dashed arrow P. Thereby, the above-mentioned effect can be acquired.

  In the second modified example shown in FIG. 8, a second display image 14a representing a set of leaves of a large number of trees instead of the wheel shape and a first display image 14b arranged so that a plurality of unit images 14c constitute the ground. The eco display device 14 (liquid crystal panel 140) is configured to display. The unit image 14c represents humus, which is soil that has fallen and accumulated, and the first display image 14b represents the ground where a lot of humus has gathered. The second display image 14a displays the eco numerical value Ev (km / L) according to the amount of fallen leaves falling in the direction of the dashed arrow P. Thereby, the above-mentioned effect can be acquired.

  In the third modified example shown in FIG. 9, a first display image in which a part-shaped second display image 14 a that collects an image of the earth instead of the wheel shape and a plurality of circular unit images 14 c are arranged in a ring shape. The eco display device 14 (liquid crystal panel 140) is configured to display 14b. In addition, the second display image 14a displays the eco value Ev (km / L) according to the speed at which the image-like earth is completed. Thereby, the above-mentioned effect can be acquired.

  In FIG. 8D and FIG. 9D, the background color is changed when the accumulated value of ecological traveling reaches a predetermined value. Thereby, it can be displayed with emphasis that the accumulated value of ecological driving has reached a predetermined value.

  In the fourth modification shown in FIG. 10, the eco display device 14 (liquid crystal panel 140) is configured to display the number of repetitions 14d with respect to the display shown in FIG. Further, without terminating the control flow in step 14 shown in FIG. 5, the number N of unit images 14c is set to zero, the process returns to step S2, and steps S2-S14 are repeated. That is, when the number N of unit images 14c representing the accumulated value reaches 10, the meter control device 15 is configured so that 10 is erased and accumulation is started again from step S2 after this erase.

  In addition, by adding 1 to the number of erasures of a predetermined value, the determination / calculation means 15a is configured to calculate the number of repetitions 14d for which accumulation has been started again, and the eco display device 14 ( A liquid crystal panel 140) is configured.

  As described above, according to the fourth modification, it is possible to display that the accumulated value of the ecological traveling has reached the predetermined value, and before the predetermined value is reached, how much relative ratio to the predetermined value is achieved. It is possible to repeatedly recognize whether the economy and ecological driving are accumulated. Further, since the repetition number 14d obtained by adding 1 to the predetermined number of erasures is displayed, the repetition number 14d can be recognized.

  In the fourth modified example shown in FIG. 11, the eco display device 14 is configured by a dial 14 e, a pointer 14 f, an eco accumulation bar 14 g and the like instead of the liquid crystal panel 140. The dial 14e is formed with characters and scales of the eco value Ev (km / L), and the pointer 14f rotates on the front surface of the dial 14e to point to the characters and scales, whereby the eco value Ev (km / L). L) is configured to display. The eco-accumulation bar 14g is configured to display a cumulative value of the eco-value Ev (km / L) by disposing a light-emitting diode (not shown) behind the eco-accumulation bar 14g. Thereby, the above-mentioned effect can be acquired.

  The determination value is not limited to 50 km / L. This is because the hybrid vehicle 1 is subjected to different travel control depending on the vehicle type (for example, a sports car or a general vehicle), and the determination value that the traveling of the hybrid vehicle 1 is neither ecological nor bad from an ecological viewpoint is: This is because it can vary depending on the vehicle type.

  Further, the eco value Ev (km / L) is not necessarily calculated by subtracting the judgment value of 50 km / L from the instantaneous fuel consumption Fe (km / L). Instead of the instantaneous fuel consumption Fe (km / L), it is possible to use an average fuel consumption (km / L) updated every 10 seconds.

  Further, the travel distance is not limited to the unit amount conversion distance by the fuel consumed from the present time to a predetermined short time before, such as the instantaneous fuel efficiency Fe (km / L) and the average fuel efficiency (km / L). It is possible to use a cruising range (km / L) representing an estimated cruising range in terms of 1 liter based on this average fuel consumption (km / L).

  Moreover, although the case where the combination meter 10 which is the display apparatus for vehicles by this invention was applied to the hybrid vehicle 1 was demonstrated to the example in the above-mentioned example, it is not restricted to this. That is, the combination meter 10 can be applied to an automobile that is driven by the engine 4 that consumes fuel.

  As described above, the combination meter 10 that is a vehicle display device according to the present invention is a combination meter 10 that is used in the hybrid vehicle 1 that is an automobile that is driven by the engine 4 that consumes fuel. By determining whether or not the instantaneous fuel consumption Fe (km / L) having a converted travel distance is larger than the determination value, it is determined whether or not the traveling of the hybrid vehicle 1 is economy / ecological traveling and the instantaneous fuel consumption Fe ( km / L) is greater than the determination value, the determination / calculation means 15a, which is a determination means for determining that the traveling is economy / ecological traveling, and the instantaneous fuel consumption Fe when it is determined that the traveling is economy / ecological traveling. Economy and ecological running by subtracting the judgment value from (km / L) Is determined as an eco-value Ev (km / L) and the eco-value Ev (km / L) is accumulated over time, and a determination / calculation unit 15a that is a calculation unit that calculates a cumulative value and displays the cumulative value. And an eco display device 14 as display means.

  Accordingly, it is possible to provide a display device for a vehicle that can display how much the economy / ecological driving is accumulated.
