  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

<System configuration>
FIG. 1 is a functional block diagram of the operation control system. The driving control system 1 illustrated in FIG. 1 includes a navigation device 10 mounted on a vehicle, a detection device 20, a control mechanism 30, and an automatic driving control computer 40. In the present embodiment, an example in which the automatic operation control computer 40 is provided has been described. However, in the present invention, the automatic operation control computer 40 is not an essential configuration, and the automatic operation control computer 40 may be omitted.

  The navigation device 10 sets destinations and waypoints according to user operations such as drivers and passengers, and performs route guidance (navigation) to the destination. In addition, the navigation device 10 provides the automatic operation control computer 40 with route information including the set destination and waypoint, thereby causing the automatic operation to the destination to be performed. The navigation device 10 is an embodiment of the route setting device in the present invention. Note that the navigation device 10 may be an audio / visual / navigation integrated electronic device (also referred to as an AVN device) having an audio function for reproducing music and a visual function for reproducing moving images and displaying television broadcasts. good.

The navigation device 10 includes a display device 11, a selection display control unit 12, an operation detection unit 13, a confirmation display control unit 14, a route setting unit 15, a position information acquisition unit 16, an output control unit 17, and a GPS (Global Positioning System) antenna. 101, an acceleration sensor 102, and a speaker 103 are provided.

  The display device 11 includes a display element (not shown) such as a liquid crystal display element or an organic EL (Electro-Luminescence) panel, and displays an image. Further, the display device 11 includes a touch panel (not shown) arranged so as to overlap the display area of the display element.

  The selection display control unit 12 extracts a plurality of place options such as a service area and a parking area that can be set as destinations from the map information and displays them on the display device 11.

  The operation detection unit 13 detects a user operation such as a user selection operation for an option. The operation detection unit 13 of the present example performs an operation so that the user touches an operation target such as an option displayed on the display device 11 based on an input from a touch panel arranged so as to overlap the display area of the display device 11 ( Hereinafter, information (operation information) indicating the touch operation is detected when the touch operation is performed.

  For example, the operation detection unit 13 detects the touched position (touched position) of the touch panel, the time of the touch, the movement of the touched position, the contact strength, and the like as user operation information. Further, when the operation detection unit 13 detects the touched position, the operation detection unit 13 detects it as an operation (selection operation) for selecting an option displayed at the position. Further, the operation detection unit 13 is not limited to simply detecting the contact position, and long presses the contact for a predetermined time or longer, detects the contact for the predetermined time or less as a tap, and detects the movement of the contact position as a flick. When performed, it may be detected that a selection operation has been performed on the operation target displayed at the position. Furthermore, the operation detection unit 13 may detect a selection operation for the operation target displayed at this position when the contact is made with a strength (pressure) of a predetermined value or more.

  Note that the touch panel is not limited to being provided so as to overlap with the display area of the display device 11, and may be an input device such as a touch pad arranged at a position different from the display device 11. For example, the display device 11 may be a head-up display that displays display contents on the inside of a windshield, and the touch panel may be an input device such as a touch pad arranged on a center console or the like. In this case, the user performs a touch operation on the touch pad, operates a cursor (pointer) displayed on the head-up display, and performs an operation such as a selection operation on the operation target displayed on the head-up display. The touch pad inputs the operation information to the navigation device 10, and the operation detection unit 13 detects an operation such as a selection operation by the user based on the operation information.

  When the confirmation display control unit 14 detects a selection operation for an option, if the display distance between the option and another option on the display device 11 is less than the threshold, in other words, the display of the options is dense. Then, a confirmation screen for confirming whether or not to approve the destination setting based on the option for which the selection operation has been performed is displayed on the display device 11. When the display distance is greater than or equal to the threshold, in other words, when the display of options is not dense, the confirmation display control unit 14 does not display the confirmation screen.

  The route setting unit 15 selects an option for which the selection operation is performed when it is detected that an approval operation for approving the destination setting is performed on the confirmation screen, or when the display distance is equal to or greater than the threshold value. Set the destination based on.

  The position information acquisition unit 16 receives GPS signals from a plurality of GPS satellites via the GPS antenna 101, and calculates vehicle position information based on the GPS signals. Further, the position information acquisition unit 16 may have a function of autonomously obtaining the position of the vehicle based on the movement of the vehicle detected by the acceleration sensor 102 or the gyro.

  The output control unit 17 controls display output to the display device 11 and audio output from the speaker 103. For example, the output control unit 17 superimposes the route information set by the route setting unit 15 and the position of the host vehicle on the map information and displays them on the display device 11 to perform route guidance. Further, the output control unit 17 outputs the route information set by the route setting unit 15 and the position information acquired by the position information acquisition unit 16 to the automatic operation control computer 40.

  The detection device 20 is a device that detects the situation around the vehicle and the traveling state of the vehicle, and in this example, includes a camera 21, a millimeter wave radar 22, and a vehicle speed sensor 23.

  The camera 21 captures an image around the vehicle. A plurality of cameras 21 may be provided in accordance with the shooting direction, such as the front, rear, and side of the vehicle. For example, the ECU 24 compares the current image captured by the camera 21 and the past image with reference to the road surface (plane), and detects an obstacle (three-dimensional object) based on the difference. Further, the ECU 24 extracts road information such as lanes and road signs from the current image taken by the camera 21. Then, the ECU 24 inputs obstacle information and road information to the automatic driving control computer 40.

  The millimeter wave radar 22 transmits a millimeter wave (wavelength of about 1 to 10 mm and a frequency of 30 G to 300 GHz) around it, receives a reflected wave from a target, and deviates between the transmitted wave and the reflected wave. The relative distance to the target, the relative speed of the target, etc. are obtained based on The ECU 25 inputs information on the relative distance to the target and the relative speed of the target obtained by the millimeter wave radar 22 to the automatic operation control computer 40.

  The vehicle speed sensor 23 detects a pulse signal (vehicle speed pulse) accompanying rotation of the axle or the like. The ECU 26 obtains the vehicle speed based on the vehicle speed pulse detected by the vehicle speed sensor 23 and inputs it to the navigation device 10 and the automatic operation control computer 40.

  The control mechanism 30 is a mechanism that adjusts at least one of acceleration, steering, and braking of the vehicle in accordance with the control of the automatic driving control computer 40. The control mechanism 30 of this example includes a steering control mechanism 31, a brake control mechanism 32, and a throttle control mechanism 33. The steering control mechanism 31 performs steering based on the control of the automatic driving control computer 40 to adjust the traveling direction of the vehicle. The brake control mechanism 32 operates a brake based on the control of the automatic operation control computer 40 to decelerate or stop the vehicle. The throttle control mechanism 33 adjusts the acceleration of the vehicle by supplying fuel to the engine and supplying power to the motor based on the control of the automatic operation control computer 40.

  The automatic operation control computer 40 controls the control mechanism 30 according to the situation around the vehicle detected by the detection device 20, and performs an automatic operation of driving the vehicle to the destination according to the route information acquired from the navigation device 10. In this example, the automatic driving is a state in which the automatic driving control computer 40 controls at least one of acceleration, steering, and braking of the vehicle. For example, at the level of automation defined by the Japanese government or the US Department of Transportation's Road Traffic Safety Administration (NHTSA), the automatic operation control computer 40 performs control of level 1 or higher, preferably level 3 or higher.

FIG. 2 is a diagram illustrating an example of a hardware configuration of the navigation device 10 or the automatic driving control computer 40. As illustrated in FIG. 2, the navigation device 10 or the automatic driving control computer 40 includes a CPU (Central Processing Unit) 201, a memory 202, and an input / output IF 203 that are connected to each other via a connection bus 210. The CPU 201 is a central processing unit that controls the entire navigation device 10 or the entire automatic operation control computer 40. The CPU 201 is also called a processor. However, the CPU 201 is not limited to a single processor and may have a multiprocessor configuration. A single CPU 201 connected by a single socket may have a multi-core configuration.

The memory 202 includes a main storage device and an auxiliary storage device. The main storage device is used as a work area for the CPU 201, a storage area for programs and data, and a buffer area for communication data. The main storage device is formed by, for example, a random access memory (RAM) or a combination of a RAM and a read only memory (ROM). The main storage device is a storage medium in which the CPU 201 caches programs and data and expands a work area. The main storage device includes, for example, a flash memory, a RAM (Random Access Memory), and a ROM (Read Only Memory). The auxiliary storage unit is a storage medium that stores programs executed by the CPU 201, operation setting information, and the like. The auxiliary storage device is, for example, an HDD (Hard-disk Drive), an SSD (Solid State Drive), an EPROM (Erasable Programmable ROM), a flash memory, a USB memory, a memory card, or the like.

  The input / output IF 203 is an interface for inputting / outputting data to / from devices such as a sensor, an operation unit, and an ECU connected to the navigation device 10 or the automatic operation control computer 40. Note that a plurality of the above-described components may be provided, or some of the components may not be provided.

In the navigation device 10, the CPU 201 executes the route setting program, thereby causing the selection display control unit 12, the operation detection unit 13, the confirmation display control unit 14, the route setting unit 15, the position information acquisition unit 16, and the like illustrated in FIG. It functions as each processing unit such as the output control unit 17. However, at least a part of the processing of each processing unit may be provided by a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or the like. Also,
At least a part of each of the processing units may be a dedicated LSI (large scale integration) such as a field-programmable gate array (FPGA) or other digital circuit. Also,
It is good also as a structure which includes an analog circuit in at least one part of each said process part.

<Route setting method>
FIG. 3 is a diagram showing a processing procedure of a route setting method executed by the navigation device 10 according to the route setting program.

  The navigation apparatus 10 starts the process of FIG. 3 when receiving an instruction to start the process or when the electric system of the vehicle is turned on.

  First, the navigation device 10 extracts points that can be set as destinations or waypoints from the map information, and displays them on the display device 11 as options (step S10). FIG. 4 shows options 41 to 43 by extracting a predetermined number (three in the example of FIG. 4) of service areas and parking areas existing ahead of the current point while traveling on a highway. FIG. 5 also shows convenience stores, gas stations (charging stations in the case of electric vehicles) and roadside stations that are present in the direction of travel from the current location while driving on general roads, and show them as options 44 to 46. Yes.

  Next, the navigation device 10 determines whether or not a selection operation for the options 41 to 46 has been performed (step S20). Here, when it is determined that a selection operation such as a touch operation is not performed on the options 41 to 46 (No in step S20), the navigation device 10 ends the process of FIG. In addition, the detection of the operation with respect to the options 41 to 46 is not limited to the touch operation, and an operation such as a long press, a tap, a double tap, a flick, or a strong press beyond a predetermined value may be detected.

  On the other hand, if it is determined that the selection operation has been performed (step S20, Yes), the navigation device 10 determines whether the display distance on the display device 11 between the option for which the selection operation has been performed and another option is less than a threshold value. In other words, it is determined whether the display of options is dense (step S30). Here, when it is determined that the display of the options is dense (step S30, Yes), that is, when the display distance is less than the threshold, the navigation device 10 sets the destination based on the option for which the selection operation has been performed. A confirmation screen for confirming whether or not to approve is displayed on the display device 11 (step S40).

  FIG. 6 is a diagram illustrating a display example of a confirmation screen. In FIG. 6, as the confirmation screen 61, a message 62 urging confirmation of the selected point such as “Do you want to set △ □ GS as a detour?” And whether to approve such as “Yes” or “No”. These options 63 and 64 are displayed.

  Then, the navigation device 10 determines whether or not it has been detected that the user has performed an approval operation for approving the destination setting on the confirmation screen (step S50). Here, when it is determined that the approval operation has not been performed (step S50, No), for example, when the “No” option 64 on the confirmation screen 61 is selected, the processing of FIG. 3 is performed without setting the destination. Exit.

  On the other hand, when it is determined that the approval operation has been performed (Yes at Step S50), for example, when the “Yes” option 63 on the confirmation screen 61 is selected, or at Step S30, it is determined that the display of the options is not dense. When it is done (step S30, No), the navigation apparatus 10 sets the destination based on the option for which the selection operation has been performed (step S60). The navigation apparatus 10 ends the process of FIG. 3 after setting the destination, but repeatedly executes the process of FIG. 3 while the electric system of the vehicle is ON.

  As described above, the navigation device 10 according to the present embodiment prevents the setting of an erroneous destination by displaying a confirmation screen if the display of options for setting the destination is dense. If the display of options is not dense, setting the destination without displaying the confirmation screen reduces the troublesomeness of the approval operation.

  FIG. 7 is an explanatory diagram of the display distance. In FIG. 7, L11 and L12 are distances between the outer edge of each option and the outer edges of other adjacent options (hereinafter also referred to as the distance between the outer edges), and L21 and L22 are the centers of the options, This is the distance between the centers of other adjacent options (hereinafter also referred to as center distance). In step S30 of FIG. 3, the display distance to be compared with the threshold value may be the distance between the outer edges L11 and L12, or may be the distance between the centers L21 and L22. When each of the options S1 to S4 is adjacent to the plurality of options S1 to S4 and a plurality of display distances are obtained, the shortest of these may be used as the display distance to be compared with the threshold value in step S30. For example, since the center-to-center distance L22 with the option S2 is longer than the center-to-center distance L21 with the option S3, the center-to-center distance L21 may be adopted as the display distance for comparison with the threshold value.

  Moreover, it is good also as a structure which calculates | requires display distance about several directions and compares the display distance of each direction with the threshold value set for the said direction. In the example of FIG. 7, the display distance is obtained in two predetermined directions (for example, the vertical direction (Y-axis direction) and the horizontal direction (X-axis direction) of the image). In FIG. 7, the display distance L11 is the distance between the outer edges in the vertical direction, and the display distance L12 is the distance between the outer edges in the horizontal direction. The display distance L21 is the center-to-center distance in the vertical direction, and L22 is the center-to-center distance in the horizontal direction. Further, when the distance between the outer edges and the distance between the centers are obtained in a plurality of directions as described above, a threshold value of the distance between the outer edges in the same direction may be set according to the length of the distance between the centers. For example, if the options S1 to S4 have a horizontally long shape and the distance between the centers in the horizontal direction is sufficiently long, even if the contact position when performing the selection operation is slightly shifted in the horizontal direction, another option is selected by mistake. There is little possibility to end up. For this reason, when the center-to-center distance is equal to or greater than the first threshold, the threshold of the distance between the outer edges in the same direction is set to be smaller than a predetermined value. On the other hand, when the distance L21 between the centers in the vertical direction is short as shown in the options S3 and S4, the distance between the outer edges L11 is also short and displayed densely. There is a high possibility that it will end. For this reason, when the distance between the centers is less than the first threshold, the threshold of the distance between the outer edges in the same direction is set to be larger than a predetermined value.

<Modification>
FIG. 8 is a diagram illustrating a modification of the route setting method. In the modification of FIG. 8, the configuration for changing the threshold value is different according to the traveling state of the vehicle, and the other configurations are the same as those in the above-described embodiment. For this reason, a different structure from the above-mentioned embodiment is mainly demonstrated, and description is abbreviate | omitted about the same structure.

  The navigation device 10 that has started the process of FIG. 8 performs steps S10 and S20 in the same manner as described above, and when it is determined that the selection operation has been performed in step S20 (step S20, Yes), detects the traveling state of the vehicle. (Step S24). Here, the traveling state of the vehicle is, for example, the vehicle speed detected by the vehicle speed sensor 23, the acceleration (eg, roll, pitch, yaw) detected by the acceleration sensor 102, the vibration detected by the acceleration sensor 102 or the vibration sensor (not shown), and the like. It is.

  And the navigation apparatus 10 calculates | requires a threshold value based on the driving state detected by step S24, and updates the threshold value used by step S30 (step S26). For example, the threshold value corresponding to the value detected in step S26 is read from the storage device in advance by storing in advance a threshold value associated with a value indicating the driving situation such as the speed, vibration, and acceleration of the vehicle. Further, a threshold value corresponding to a value indicating the driving situation may be defined by a function, and the threshold value may be calculated by substituting the value detected in step S26 into this function. The processing after step S30 is the same as that in FIG.

  As described above, in the present modification, the threshold value is changed according to the traveling state, so that the degree to which the confirmation screen is displayed can be changed according to the traveling state. For example, in a situation where there is a lot of vibration, there is a high possibility that another option will be selected by mistake, so the threshold is set large, and in a situation where there is little vibration, the threshold is set small. Further, since it is difficult to turn the line of sight toward the display device 11 when the speed of the vehicle is high, the threshold is set large, and when the speed is low, the threshold is set small. In addition, when the acceleration applied to the vehicle is large, the contact position of the user's finger or the like who performs the selection operation is likely to shift, so the threshold is set large, and when the acceleration is small, the threshold is set small.

<Operation and effect of the embodiment>
As described above, the navigation device (route setting device) 10 according to the present embodiment sets an incorrect destination by displaying a confirmation screen if the display of options for setting the destination is dense. If the display of choices is not crowded, setting the destination without displaying the confirmation screen reduces the troublesomeness of the approval operation. Thereby, it is possible to prevent the destination from being set to the wrong destination while facilitating the destination setting operation.

  Moreover, the navigation apparatus 10 of this embodiment changes a threshold value according to the driving | running | working state of a vehicle. For example, the threshold value is greatly changed in a driving state where an error in the selection operation is likely to occur, and the threshold value is changed small in a driving state where an error in the selection operation is unlikely to occur. Both the prevention of setting to the ground and the reduction of the labor of the confirmation screen are compatible.

  In the navigation device 10 of the present embodiment, the traveling state is at least one of the speed, vibration, and acceleration of the vehicle. Thereby, the threshold value is set according to an element that easily affects the selection operation, and both the prevention of setting the wrong destination and the trouble of the operation on the confirmation screen are compatible.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.

Moreover, although the example which used the navigation apparatus 10 as a route setting apparatus was shown in the said embodiment, not only this but a smart phone, a tablet PC (Personal Computer), a notebook personal computer, a portable game machine, a wearable computer, etc. There may be.
