Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a control method for an on-vehicle air conditioning system according to an exemplary embodiment. As shown in fig. 1, the method may include the following steps.
In step S11, it is detected whether or not the wiper of the vehicle is in an on state.
In step S12, when it is detected that the wiper blade is in the on state, the air conditioning system of the vehicle is controlled to turn on the defrost function.
As mentioned above, when exposed to rain and snow weather, the vehicle windshield may have beads of water. If the vehicle is running, the driver can open the windscreen wiper to wipe off water drops on the windscreen. The wiper may include a front windshield wiper, and may also include a rear windshield wiper. When the windscreen wiper is usually opened, the environment is wet and cold, fog is easily formed in a cab, and a vehicle window needs to be demisted. Therefore, in the present disclosure, when it is detected that the wiper blade is opened, the air conditioning system of the vehicle is automatically controlled to turn on the defrost function. Specifically, the windscreen wiper can be periodically detected, and the function of starting and defrosting the air conditioner can be automatically triggered by starting the windscreen wiper.
When the windscreen wiper is opened, the vehicle is in a whole vehicle power-on state, the air conditioning system is powered on, namely the air conditioning controller is opened, and therefore the air conditioning system can be conveniently controlled to start a defrosting function.
Through the technical scheme, when the windscreen wiper is in the opening state, the air-conditioning system of the vehicle is controlled to start the defrosting function. Therefore, the defrosting can be automatically controlled to start when needed, the trouble that a driver manually operates to start the defrosting function is eliminated, and the driving safety is improved. And moreover, the system does not need to be provided with more sensors to control the automatic defrosting function, the control strategy is simple, and the failure is not easy to occur.
Sometimes, fog is gradually formed in the cab after the wiper is opened for a certain period of time. Therefore, the defrosting function of the air conditioning system can be automatically started after the windscreen wiper is started for a preset time. Fig. 2 is a flowchart of a control method for an in-vehicle air conditioning system according to another exemplary embodiment. As shown in fig. 2, the step of controlling the air conditioning system of the vehicle to turn on the defrost function (step S12) when it is detected that the wiper blade is in the on state on the basis of fig. 1 may include the following steps.
In step S121, when it is detected that the wiper is in the on state, time counting is started.
In step S122, the air conditioning system of the vehicle is controlled to turn on the defrost function when a predetermined turn-on duration is reached.
Specifically, the wiper blade may be periodically detected, and timing may be started immediately upon detection of the opening of the wiper blade. It may also be arranged that the opening of the wiper automatically triggers the start of the timer. The predetermined on-time may be set according to the region, the climate, etc., or may be set according to experience or experiment, for example, may be set to 30 s. And when the timing reaches the starting duration, controlling to start the defrosting function.
In the embodiment, considering that fog in the vehicle is less when rain and snow begin to exist, the defrosting function is started for a certain time after the windscreen wiper is started, so that the defrosting time is more reasonable, and the power consumption of the vehicle is saved. In addition, sometimes the opening of the wiper blade is not caused by water drops on the windshield due to rainy and snowy weather but by accidental factors such as washing of the windshield. In these cases, the normal wiper blade does not last too long. In the embodiment, the conditions that defrosting does not need to be started can be eliminated by setting the preset starting time, so that unnecessary starting is avoided, and defrosting is more intelligent.
Considering that the amount of rainfall tends to decrease when the wiper blade is closed, the amount of fog in the vehicle is also decreased accordingly. The defrosting function of the air conditioner can be turned off. Fig. 3 is a flowchart of a control method for an in-vehicle air conditioning system according to still another exemplary embodiment. As shown in fig. 3, on the basis of fig. 1, after the step of controlling the air conditioning system of the vehicle to turn on the defrost function when it is detected that the wiper blade is in the on state (step S12), the method may further include the following steps.
In step S13, it is detected whether or not the wiper blade is closed.
In step S14, when it is detected that the wiper blade is closed, the air conditioning system of the vehicle is controlled to turn off the defrosting function.
That is, in the embodiment of fig. 1, when it is detected that the wiper blade is opened, the state of the wiper blade may not be detected. In the embodiment of fig. 3, after it is detected that the wiper blade is turned on, it may be detected (for example, periodically) whether the wiper blade is turned off. And once the wiper is detected to be closed, automatically controlling the air conditioning system to close the defrosting function. Alternatively, the wiper blade can be set to be turned off to trigger the air conditioning system to turn off the defrosting function.
In this embodiment, it is considered that the driver closes the wiper blade when the amount of rain and snow is small, and therefore, the air conditioner is controlled to close the defrosting function by determining that the humidity of the environment outside the vehicle is reduced by closing the wiper blade. Therefore, the defrosting function of the air conditioner can be automatically closed when defrosting is not needed, the trouble that a driver manually operates to close the defrosting function is eliminated, and the driving safety is improved. And moreover, the system does not need to be provided with more sensors to control the automatic defrosting closing function, the control strategy is simple, and the failure is not easy to occur.
Sometimes, the fog in the cab is gradually dissipated after the wiper is closed for a while. Therefore, the defrosting function of the air conditioning system can be automatically turned off after the wiper blade is turned off for a predetermined time. Fig. 4 is a flowchart of a control method for an in-vehicle air conditioning system according to still another exemplary embodiment. As shown in fig. 4, the step of controlling the air conditioning system of the vehicle to turn off the defrost function (step S14) when it is detected that the wiper blade is turned off on the basis of fig. 3 may include the following steps.
In step S141, when it is detected that the wiper blade is closed, time counting is started.
In step S142, the air conditioning system of the vehicle is controlled to turn off the defrost function when a predetermined turn-off duration is reached.
Specifically, the wiper blade may be periodically detected after being turned on, and timing may be started immediately upon detection of turning off of the wiper blade. It may be arranged that the turning off of the wiper automatically triggers the start of the timer. The predetermined closing time period may be set according to the conditions of the region, the climate, etc., or may be set according to experience or experiment, for example, may be set to 1 min. And when the timing reaches the closing duration, controlling to close the defrosting function.
In the embodiment, when the windscreen wiper is just closed, the fog in the automobile is still large, the automobile window needs to be demisted continuously, the closing of the defrosting function is delayed for a certain time than the closing of the windscreen wiper, and therefore the time for closing the defrosting function is more reasonable, and defrosting is more intelligent.
In addition, the size of the rainfall can be judged according to the swinging frequency of the windscreen wiper so as to determine whether the defrosting function of the air conditioner is started or not. Fig. 5 is a flowchart of a control method for an in-vehicle air conditioning system according to still another exemplary embodiment. As shown in fig. 5, the step of controlling the air conditioning system of the vehicle to turn on the defrost function (step S12) when it is detected that the wiper blade is in the on state on the basis of fig. 1 may include the following steps.
In step S123, when it is detected that the wiper blade is in the on state, the oscillating frequency of the wiper blade is acquired.
In step S124, when the oscillating frequency of the wiper blade is greater than a predetermined frequency threshold, the air conditioning system of the vehicle is controlled to turn on the defrost function.
The oscillating frequency of the wiper blade can be simply obtained through the gear position of the wiper blade, and can also be obtained through a sensor. When the wiper blade is provided with a plurality of shift positions, generally, the greater the amount of rain, the greater the frequency with which the wiper blade is controlled by the driver to swing. When the oscillating frequency of the windscreen wiper is greater than a preset frequency threshold value, the humidity can be considered to reach a certain degree, and the defrosting function of the air conditioner needs to be started. On the contrary, when the oscillating frequency of the wiper blade is smaller than the preset frequency threshold, the humidity is not considered to reach a certain degree, and the defrosting function of the air conditioner is not required to be started. The predetermined frequency threshold may be set according to the region, climate, etc., or may be set according to experience or experiment, for example, 2 times/s. And when the swing frequency is greater than a preset frequency threshold value, controlling to start the defrosting function.
For example, the wiper blade is provided with two gears of a fast speed and a slow speed. When the swing is carried out in a fast gear, the swing frequency is larger than a preset frequency threshold value, and when the swing is carried out in a slow gear, the swing frequency is smaller than the preset frequency threshold value. Therefore, when the windscreen wiper swings at a fast gear, the defrosting function of the air conditioner can be automatically controlled to be started, and when the windscreen wiper swings at a slow gear, the defrosting function of the air conditioner is not started.
In this embodiment, the degree of humidity is determined according to the oscillating frequency of the wiper blade, so as to determine whether to start the defrosting function of the air conditioner. Therefore, the defrosting time is more reasonable, and the defrosting is more intelligent.
