At present, a large number of models are equipped with individually controllable front and rear air conditioners. During use, the front and rear air conditioners connected by the air duct are individually controlled to meet the use needs of the front and rear passengers. However, since the front and rear temperatures of the passenger compartment of electric vehicles are controlled separately, the driver is required to control the temperature control systems of the front and rear passenger areas separately while driving the vehicle, which distracts the driver's attention and reduces the safety of vehicle driving. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0024] At present, since the front and rear temperatures of the passenger compartment of electric vehicles are controlled separately, the driver is required to operate the temperature control systems of the front and rear passenger areas separately while driving the vehicle, which distracts the driver's attention and reduces the safety of vehicle driving.

[0025] Based on this, an embodiment of the present application provides a vehicle temperature control method, the method comprising: obtaining the temperature of at least one area inside the vehicle, and the target adjustment temperature of the first area in the at least one area set by the user. The second area is any area outside the first area in the at least one area. In response to the temperature synchronization control instruction, the first opening of the air supply damper in the first area is determined according to the target adjustment temperature, the first temperature and the external information collected by the sensor of the vehicle. The second opening of the air supply damper in the second area is determined according to the target adjustment temperature, the second temperature and the external information. The air supply damper in the first area is controlled by the first opening and the air supply damper in the second area is controlled by the second opening, so that the difference between the adjusted temperature of the first area and the adjusted temperature of the second area is less than or equal to the temperature threshold. This process simplifies the user's operation and control procedures of the vehicle temperature control system by synchronously controlling the temperatures of the first area and the second area, which can facilitate the user to focus on the front view and the control of the vehicle, thereby increasing driving safety.

[0026] The following will describe the implementation of the embodiment of the present application in detail with reference to the accompanying drawings. The vehicle temperature control method provided in the embodiment of the present application can be executed by a vehicle temperature control system. Figure 1 As shown, the vehicle temperature control system 100 may include: a front air conditioning system 101 , a rear air conditioning system 102 , a thermal management control 103 and a control system 104 .

[0027] The front air conditioning system 101 is used to adjust the air flow and temperature of the front area of ​​the vehicle. The front air conditioning system 101 may include a front evaporator, a front fan, a front damper and other devices. The front temperature sensor is arranged in the front area of ​​the vehicle to detect the actual temperature of the front area, and sends the detected actual temperature to the control system 104 through the communication connection with the control system 104.

[0028] The rear air conditioning system 102 is used to adjust the air flow and temperature of the rear area of ​​the vehicle. The rear air conditioning system 102 may include a rear evaporator, a rear fan, and a rear air door. The rear temperature sensor is located in the rear area of ​​the vehicle to detect the actual temperature of the rear area, and sends the detected actual temperature to the control system 104 through the communication connection with the control system 104.

[0029] The thermal management control 103 is used to determine the target adjustment temperature of the front air-conditioning system 101 and the rear air-conditioning system 102 in response to the user's temperature control command, or to determine the target adjustment temperature of the front air-conditioning system 101 and the target adjustment temperature of the rear air-conditioning system 102 respectively, and send the target adjustment temperature to the control system 104.

[0030] Among them, the thermal management control 103 is used to receive the driver's instructions to turn on or off the temperature synchronization control of the front and rear passenger areas, the target adjustment temperature, and the temperature data of the front and rear passenger areas at the current moment. It can be in the form of a physical button, such as a button or knob in the central control switch, or it can be a virtual button or voice control in the human-computer interaction system.

[0031] Specifically, after the vehicle is powered on, the thermal management control is first initialized. After the user sets the target temperature adjustment and issues a command for synchronously controlling the temperatures of the front and rear passenger areas, it begins to receive the temperature data of the front and rear passenger areas at the current moment.

[0032] The control system 104 is used to communicate with the front air conditioning system 101, the rear air conditioning system 102 and the thermal management control 103, and to issue control instructions to the front air conditioning system 101 and the rear air conditioning system 102 according to the temperature data received from the front air conditioning system 101, the rear air conditioning system 102 and the thermal management control 103. For example, the front row temperature of the front row temperature sensor in the front air conditioning system 101 and the target adjustment temperature sent by the thermal management control 103 are received, and the working state of the front air conditioning system 101 is controlled according to the target adjustment temperature and the front row temperature to achieve independent temperature adjustment of the front air conditioning system 101. The control system 104 can also coordinate the operation of the front air conditioning system 101 and the rear air conditioning system 102, and through the vehicle temperature control method provided in the embodiment of the present application, the temperature of the front air conditioning system 101 and the rear air conditioning system 102 are synchronously controlled using the target adjustment temperature to ensure the stability and comfort of the temperature inside the vehicle.

[0033] On the one hand, an embodiment of the present application provides a vehicle temperature control method, which can be Figure 1 The vehicle temperature control system 100 shown in FIG. Figure 1 As shown, the method may include: S201, in response to a temperature synchronization control instruction, obtaining a temperature of at least one area inside a vehicle and a target adjustment temperature of a first area among the at least one area set by a user.

[0034] Among them, the temperature synchronization control instruction can be triggered by the user through a temperature synchronization button, a temperature synchronization virtual button or voice control.

[0035] For example, the user may trigger a temperature synchronization button or a temperature synchronization virtual button in the thermal management control so that the thermal management control receives the temperature synchronization control instruction, or the user may trigger the thermal management control through voice control so that the thermal management control receives the temperature synchronization control instruction.

[0036] It should be noted that when the vehicle is started, the thermal management controls need to be initialized.

[0037] Specifically, first determine whether the temperature synchronization control instruction for the user in the thermal management control is initialized. If not initialized, initialize the temperature synchronization instruction signal of the thermal management for the front and rear passenger areas. This initialization is used to turn off the function of synchronizing the temperature of the front and rear passenger areas. The user needs to issue a temperature synchronization instruction by starting the temperature synchronization button in the thermal management control or by starting the temperature synchronization virtual button in the human-computer interaction system or by voice control.

[0038] At the same time, it is also necessary to determine whether the target adjustment temperature obtained by the thermal management control is initialized. If not initialized, the target adjustment temperature obtained by the thermal management control is initialized. This initialization is used to obtain the target adjustment temperature set by the user at the current moment. The user can set the target adjustment temperature by adjusting the temperature setting knob in the thermal management control or by adjusting the temperature setting virtual button in the human-computer interaction system or by issuing a temperature setting instruction through voice control.

[0039] The at least one area inside the vehicle may include a first area and a second area. The first area may be a front area inside the vehicle, and the second area may be a rear area inside the vehicle. It should be noted that the at least one area inside the vehicle may also include a third area, which may be other areas outside the front area and the rear area inside the vehicle, for example, a middle area, and the third area is equipped with an independent air conditioning system.

[0040] Further, the temperature of the front area of ​​the vehicle interior and the target adjustment temperature of the first area set by the user are obtained. For example, the temperature of the first area of ​​the vehicle interior is obtained as the first temperature. The temperature of the second area of ​​the vehicle interior is obtained as the second temperature.

[0041] S202, determining a first opening degree of an air supply damper of a first area according to a target adjustment temperature, a first temperature, and external information collected by a sensor of the vehicle.

[0042] The sensors include sunlight sensors, vehicle exterior temperature sensors and vehicle speed sensors. External information includes solar radiation intensity, vehicle exterior ambient temperature and vehicle speed.

[0043] In a possible implementation, a sunlight sensor is used to collect solar radiation intensity, an external temperature sensor is used to collect external ambient temperature, and a vehicle speed sensor is used to collect vehicle speed. The air supply temperature of the first area is determined according to the first temperature, the target adjustment temperature, the solar radiation intensity, the external ambient temperature, and the vehicle speed. The first opening degree is determined according to the air supply temperature of the first area.

[0044] Specifically, a set of historical solar radiation intensities for a first preset time period, a set of historical vehicle exterior temperatures for a second preset time period, and a set of historical vehicle speeds for a third preset time period are obtained. Based on the first preset time period and the set of historical solar radiation intensities, the average solar radiation intensity of the vehicle in the first preset time period is determined. Based on the second preset time period and the historical vehicle exterior temperatures, the average vehicle exterior temperature of the vehicle in the second preset time period is determined. Based on the third preset time period and the set of historical vehicle speeds, the average vehicle speed of the vehicle in the third preset time period is determined. Based on the first temperature, the target adjustment temperature, the average solar radiation intensity, the average vehicle exterior temperature, and the average vehicle speed, the air supply temperature of the first area is determined.

[0045] Furthermore, a solar radiation intensity compensation value corresponding to the average solar radiation intensity, an outside temperature compensation value corresponding to the average outside temperature of the vehicle, and a vehicle speed compensation value corresponding to the average vehicle speed are determined.

[0046] For example, consider the situation where the sensor signal is unstable, such as intermittent or no sunlight (such as when the vehicle passes through a tunnel), which causes the sensor signal to be abnormal; when the car is parked, the solar radiation intensity, ambient temperature and vehicle speed signals may be disturbed when the car door is opened / closed, or the ambient temperature changes sharply due to the heat radiation from the road surface. If the control system is always controlled according to the input signals of each sensor, the air conditioning in the car will not be comfortable and the control will not be gentle enough. Therefore, a strategy of delaying the input signals of solar radiation intensity, ambient temperature and vehicle speed and taking the average of their readings can be adopted to keep the control stable.

[0047] For example, a simple moving average algorithm is used to average the solar radiation intensity, ambient temperature and vehicle speed input signals. The average solar radiation intensity value of the first preset time period constitutes a historical solar radiation intensity set, the ambient temperature of the second preset time period constitutes a historical vehicle outdoor temperature set, and the vehicle speed of the third preset time period constitutes a historical vehicle speed. The average value is used as a sensor signal to determine the throttle opening.

[0048] Among them, simple moving average is a method used to smooth time series data, such as Figure 4 As shown, the formula is as follows: SMA=(X1+X2+X3+...+Xn) / n Among them, SAM is a simple moving average; X1, X2.....Xn are the data points of the time series (such as solar radiation intensity data, ambient temperature data, and vehicle temperature data, etc.); n is the number of periods for calculating the average value, that is, the window size of the moving average (that is, the number of sensor data within a period of time).

[0049] For the vehicle air conditioning system, the time period of the moving window is appropriately 10 seconds, including 20 data (bus information is sent every 500 ms), that is, the simple moving average of the sensor data is calculated every 10 seconds.

[0050] For example, the current solar radiation intensity is 950w / m2, the solar radiation intensity compensation value is set to 3.5, and the vehicle runs at a speed of 60 kilometers per hour for 10 seconds. The first 4 seconds are outside the culvert, and the solar radiation intensity compensation value data (8) remain unchanged. In the middle 3 seconds, it passes through a 50-meter culvert. At this time, the solar radiation intensity is less than 500w / m2, and the radiation intensity compensation value data (6) are set to 0. After leaving the culvert, the solar radiation intensity changes to 950w / m2 within 3 seconds, and the solar radiation intensity compensation value is still 3.5. The data (6) remain unchanged. Therefore, the simple moving average of the solar radiation intensity value at this stage is: E=(3.5x 8+0x6+3.5x6) / 20=2.45, which is used as the solar radiation intensity compensation value for determining the damper opening.

[0051] The supply air temperature of the first area is determined by using the first temperature, the target adjustment temperature, the solar radiation intensity compensation value, the vehicle outside temperature compensation value and the vehicle speed compensation value.

[0052] Exemplarily, the supply air temperature of the first area is determined by the following formula.

[0053] T0=aT1-T2+E1+E2+E3+e Among them, a is the correction coefficient, T1 is the first temperature, T2 is the set target temperature, E1 is the external environment temperature compensation value, E2 is the solar radiation intensity compensation value, E3 is the vehicle speed compensation value, and e is the offset.

[0054] For example, when the vehicle is running at a low or medium speed (60km / h) under high temperature (ambient temperature greater than 40℃) and strong sunlight (sunlight intensity greater than 950W / m2), the relevant parameters are obtained or set as follows: the first temperature T1 output by the in-vehicle temperature sensor is obtained to be 45℃, the set target temperature T2 is 22.5℃, and the correction coefficient a is 0.9 (when the airflow at the location where the in-vehicle temperature sensor is installed is poor, resulting in the measured temperature value being higher than the average temperature value in the vehicle, a is set to a range of less than 1 and greater than 0 to reduce the impact of the measurement data deviation caused by the poor location of the in-vehicle temperature sensor on T0. This parameter is determined during the vehicle calibration process based on the actual vehicle condition). The E1 ambient temperature compensation value is set to 4.0, the E2 solar radiation compensation value is 3.5, the E3 vehicle speed compensation value is -0.5, and the e offset is -17.

[0055] The air outlet temperature T0 can be obtained: T0=0.9x 45+4.0+3.5-0.5-17=5.8℃.

[0056] It should be noted that the correction coefficient, compensation value and offset need to be determined through actual vehicle road calibration.

[0057] For example, taking the solar radiation intensity compensation value as an example, in the actual vehicle road calibration process, in order to determine the solar radiation intensity compensation value, it is necessary to set multiple sets of solar radiation intensity compensation values ​​under a certain solar radiation intensity condition while keeping other influencing factors (such as vehicle speed, ambient temperature, target temperature, etc.) consistent, and measure the vehicle's heating and cooling performance when using different compensation values ​​for temperature control (testing the heating and cooling speed in the vehicle's cab), where the solar radiation intensity compensation value that meets the vehicle's heating and cooling performance requirements is the compensation value under the solar radiation condition. Thus, a list of solar radiation compensation values ​​corresponding to different solar radiation intensity conditions can be obtained.

[0058] Further, after the air supply temperature of the first area is determined, the feedback voltage of the servo motor corresponding to the air supply damper of the first area is controlled according to the air supply temperature of the first area, so that the air supply damper of the first area reaches a first opening degree.

[0059] For example, since the air supply damper is driven by a servo motor (or stepper motor), the feedback voltage of the drive motor can be used to map the damper opening angle. Usually, the feedback voltage range is 0-5V, and the minimum voltage change represented by a single-step rotation of the motor is 0.05V, where a large voltage value indicates that the damper opening angle is in a state of low outlet air temperature, and a small voltage value indicates that the damper opening angle is in a state of high outlet air temperature. Therefore, through actual testing of the HVAC assembly, the basic characteristic curve of the relationship between the supply air temperature and the servo motor feedback voltage (i.e., the supply air temperature and the opening characteristic curve of the supply air damper) can be obtained, such as Figure 3 As shown, this characteristic curve serves as the basic characteristic curve for determining the air door opening.

[0060] S203, determining a second opening degree of the air supply damper of the second area according to the target adjustment temperature, the second temperature and the external information.

[0061] The second area is any area outside the first area in the at least one area.

[0062] In a possible implementation, a third opening of the air supply damper of the second area is determined according to the target adjustment temperature. A second opening compensation of the air supply damper is determined using the solar radiation intensity collected by the sunlight sensor of the vehicle, the ambient temperature outside the vehicle collected by the vehicle's external temperature sensor, and the vehicle speed collected by the vehicle's speed sensor. The second opening is determined according to the third opening and the second opening compensation.

[0063] S204, controlling the air supply damper of the first area with a first opening and controlling the air supply damper of the second area with a second opening, so that the difference between the adjusted temperature of the first area and the adjusted temperature of the second area is less than or equal to a temperature threshold.

[0064] A possible implementation method is that if the minimum value of the temperature data of the front and rear passenger areas at the current moment is compared with the set target adjustment temperature, and the difference is greater than 0.5°C, the cooling function of the thermal management system is enhanced. If the maximum value of the temperature data of the front and rear passenger areas at the current moment is compared with the set target adjustment temperature, and the difference is less than -0.5°C, the heating function of the thermal management system is enhanced. If the maximum value of the temperature data of the front and rear passenger areas at the current moment is compared with the set target adjustment temperature, and the difference is not within this range, the thermal management system neither enhances the cooling function nor the heating function.

[0065] If the difference between the target temperatures of the front and rear passenger areas is set to ≤4°C, the temperature of the rear row will remain unchanged when the temperature of the front row is adjusted. If the difference between the target temperatures of the front and rear passenger areas is set to >4°C, the temperature of the rear row will follow the 4°C temperature difference when the temperature of the front row is adjusted. If the difference between the target temperatures of the front and rear passenger areas is set to >4°C, the temperature of the rear row will follow the 4°C temperature difference when the temperature of the front row is adjusted.

[0066] Another possible implementation method is that if the thermal management function is the cooling function of the vehicle temperature control system, then based on the difference between the minimum value in the temperature data of the front and rear passenger areas at the current moment and the set target adjustment temperature, the temperature of the front and rear passenger areas is lowered by running the cooling system in the vehicle temperature control system until the maximum difference between the actual temperature and the target setting temperature is ≤0.5°C, and based on the real-time changes in the temperature of the front and rear passenger areas, a decision to adjust the cooling or heating function is made, and relevant instructions are issued to the control system.

[0067] If the thermal management function is the heating function of the vehicle temperature control, then based on the difference between the maximum value of the temperature data of the front and rear passenger areas at the current moment and the set target adjustment temperature, the temperature of the front and rear passenger areas of the passenger compartment is increased by running the heating system in the vehicle temperature control system until the maximum difference between the actual temperature and the target set temperature is ≤0.5°C. Based on the real-time changes in the temperature of the front and rear passenger areas, a decision to adjust the cooling or heating function is made, and relevant instructions are issued to the actuator.

[0068] In order to further accurately control the temperature of the passenger area, it is still necessary to use the current solar radiation intensity data measured by the sunlight sensor, the current ambient temperature data measured by the outdoor temperature sensor, and the current vehicle speed data measured by the vehicle speed sensor as the basis for determining the compensation value. The difference between the current temperature of the front and rear passenger areas and the target temperature is used as the main basis for determining the supply air temperature. The larger the difference, if the heating function is required, the lower the outdoor temperature and the lower the solar radiation intensity, and the higher the set supply air temperature.

[0069] Furthermore, to improve the comfort of passengers, flexible start control can be used. For example, when starting the air supply fan in summer, in order to prevent a large amount of warm air from the fan from blowing through the air supply port, the fan start-up is delayed by 3 seconds to reduce the air temperature in the fan, thereby reducing the air supply temperature. If the passenger compartment temperature is lower than 20°C, flexible start control is not used.

[0070] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the working principle of the device. It can be understood that in order to realize the above functions, the vehicle temperature control device includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0071] The embodiment of the present application can divide the functional modules of the vehicle temperature control device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or software functional module.

[0072] It should be noted that the division of modules in the embodiments of the present application is schematic and is only a logical function division.
