[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] A temperature control method for a vehicle, a computer-readable storage medium, a temperature control device for a vehicle, and a vehicle according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0031] Figure 1 1 is a flow chart of a vehicle temperature control method according to an embodiment of the present invention.

[0032] Specifically, if Figure 1 As shown, the vehicle temperature control method includes:

[0033] S101, collecting multiple vehicle temperature influencing parameter groups and a target temperature of the vehicle.

[0034] Specifically, in this embodiment, the vehicle temperature influencing parameters include in-vehicle environmental parameters and out-vehicle environmental parameters, wherein the in-vehicle environmental parameters include in-vehicle temperature and in-vehicle humidity, and the out-vehicle environmental parameters include out-vehicle air pressure, out-vehicle wind speed, and out-vehicle solar radiation intensity. A temperature sensor and a humidity sensor can be installed in the vehicle, and an air pressure sensor, a wind speed sensor, and a solar radiation intensity sensor can be installed outside the vehicle. The in-vehicle temperature can be collected by the temperature sensor, the in-vehicle humidity can be collected by the humidity sensor, the out-vehicle air pressure can be collected by the air pressure sensor, the out-vehicle wind speed can be collected by the wind speed sensor, and the out-vehicle solar radiation intensity can be collected by the solar radiation intensity sensor. For example, the in-vehicle temperature, in-vehicle humidity, out-vehicle air pressure, out-vehicle wind speed, and out-vehicle solar radiation intensity can be collected every ten seconds and continuously collected for one minute. Then, an in-vehicle temperature parameter group, an in-vehicle humidity parameter group, an out-vehicle air pressure parameter group, an out-vehicle wind speed parameter group, and an out-vehicle solar radiation intensity parameter group can be obtained respectively, and these parameter groups are used as multiple vehicle temperature influencing parameter groups. The target temperature of the vehicle is set by the driver and passengers, and the target temperature set by the driver and passengers can be directly obtained from the system.

[0035] It should be noted that after collecting multiple vehicle temperature influence parameter groups, the multiple vehicle temperature influence parameter groups may be subjected to preprocessing operations such as cleaning, denoising and standardization to ensure the accuracy and consistency of the data in the multiple vehicle temperature influence parameter groups.

[0036] S102, calculating an average value of each vehicle temperature influencing parameter.

[0037] Specifically, in this embodiment, when the vehicle temperature influencing parameters include obtaining the indoor temperature, indoor humidity, outdoor air pressure, outdoor wind speed and outdoor solar radiation intensity, the data collection interval can be set to once every ten seconds and continued for one minute, and data at a total of six time points are collected. The collected data are grouped according to the parameter type to form an indoor temperature parameter group, an indoor humidity parameter group, an outdoor air pressure parameter group, an outdoor wind speed parameter group and an outdoor solar radiation intensity parameter group. Each parameter group contains data values ​​at six corresponding time points. The data in each parameter group are statistically processed and the average value is calculated. The indoor temperature average value is the arithmetic mean of all temperature values ​​in the indoor temperature parameter group. Similarly, the indoor humidity average value, the outdoor air pressure average value, the outdoor wind speed average value and the outdoor solar radiation intensity average value can be obtained.

[0038] The data collection interval can also be set to once every five seconds, and the data can be collected for one minute. The data collected can be grouped according to the parameter type to form an in-vehicle temperature parameter group, an in-vehicle humidity parameter group, an outside air pressure parameter group, an outside wind speed parameter group, and an outside solar radiation intensity parameter group. Each parameter group contains data values ​​at twelve corresponding time points. The data in each parameter group are statistically processed and the average value is calculated. The in-vehicle temperature average value is the arithmetic average of all temperature values ​​in the in-vehicle temperature parameter group. Similarly, the in-vehicle humidity average value, the outside air pressure average value, the outside wind speed average value, and the outside solar radiation intensity average value can be obtained. In addition, the present invention does not specifically limit the value of the data collection interval.

[0039] S103, obtaining a weight coefficient interval of each vehicle temperature influencing parameter.

[0040] Specifically, in this embodiment, when the vehicle temperature influencing parameters include obtaining the in-vehicle temperature, in-vehicle humidity, outside air pressure, outside wind speed and outside solar radiation intensity, the weight coefficient interval of each vehicle temperature influencing parameter can be obtained based on the parameters such as the average value of the in-vehicle temperature, the average value of the in-vehicle humidity, the average value of the outside air pressure, the average value of the outside wind speed and the average value of the outside solar radiation intensity, by using experimental verification, statistical analysis or machine learning. It should be noted that, assuming that the control parameter is the duty cycle of the temperature control device, the weight coefficient of the in-vehicle temperature is A, the weight coefficient of the in-vehicle humidity is B, the weight coefficient of the outside air pressure is C, the weight coefficient of the outside wind speed is D and the weight coefficient of the outside solar radiation intensity is E. At this time, the sum of the weight coefficients of the in-vehicle temperature weight coefficient A, the in-vehicle humidity weight coefficient B, the outside air pressure weight coefficient C, the outside wind speed weight coefficient D and the outside solar radiation intensity weight coefficient E is 1, that is, A+B+C+D+E=1.

[0041] S104, a plurality of vehicle temperature influencing parameters are fused according to the target temperature, the average value and the weight coefficient interval to determine a plurality of control parameters of the temperature control device in the vehicle and an energy consumption value corresponding to each control parameter group.

[0042] Specifically, in this embodiment, when the vehicle temperature influencing parameters include obtaining the indoor temperature, indoor humidity, outdoor air pressure, outdoor wind speed and outdoor solar radiation intensity, multiple vehicle temperature influencing parameter groups are collected, and the average indoor temperature, the average indoor humidity, the average outdoor air pressure, the average outdoor wind speed and the average outdoor solar radiation intensity are calculated. Multiple weight coefficient groups can be determined according to the target temperature and the weight coefficient interval of each vehicle temperature influencing parameter. For example, two weight coefficient groups are determined. The first weight coefficient group includes a weight coefficient A1 for the indoor temperature, a weight coefficient B1 for the indoor humidity, a weight coefficient C1 for the outdoor air pressure, a weight coefficient D1 for the outdoor wind speed and a weight coefficient D2 for the outdoor solar radiation intensity. Weight coefficient E1, the second weight coefficient group includes the weight coefficient A2 of the indoor temperature, the weight coefficient B2 of the indoor humidity, the weight coefficient C2 of the outside air pressure, the weight coefficient D2 of the outside wind speed and the weight coefficient E2 of the outside solar radiation intensity. In addition, the present invention may not specifically limit the number of multiple weight coefficient groups. For example, it can also be three, four or five, etc. It should be noted that the sum of the weight coefficients of the indoor temperature, the indoor humidity, the outside air pressure, the outside wind speed and the outside solar radiation intensity of each weight coefficient group is equal to 1, that is, A1+B1+C1+D1+E1=1, A2+B2+C2+D2+E2=1.

[0043] First calculate the first set of control parameters: the first set of control parameters = average temperature inside the car * weight coefficient of temperature inside the car A1 + average humidity inside the car * weight coefficient of humidity inside the car B1 + average air pressure outside the car * weight coefficient of air pressure outside the car C1 + average wind speed outside the car * weight coefficient of wind speed outside the car D1 + average solar radiation intensity outside the car * weight coefficient of solar radiation intensity outside the car E1. Similarly, the second set of control parameters can be calculated. Based on the first set of control parameters and the second set of control parameters, the basic energy consumption model is used to calculate the first energy consumption value corresponding to the first set of control parameters and the second energy consumption value corresponding to the second set of control parameters.

[0044] S105, determining an optimal control parameter from multiple groups of control parameters according to the energy consumption value corresponding to each group of control parameters, and controlling the temperature control device according to the optimal control parameter to maintain the temperature of the vehicle at a target temperature.

[0045] Specifically, in this embodiment, when the acquired control parameters are two groups, the first energy consumption value corresponding to the first group of control parameters and the second energy consumption value corresponding to the second group of control parameters are obtained, and the minimum value of the first energy consumption value and the second energy consumption value is selected, and the control parameter corresponding to the minimum energy consumption is used as the optimal control parameter. For example, if the first energy consumption value is the minimum, the first group of control parameters is used as the optimal control parameter, and if the second energy consumption value is the minimum, the second group of control parameters is used as the optimal control parameter. The control parameters include the duty cycle and / or air supply angle of the temperature control device, and then the temperature control device can be controlled according to the optimal control parameters to maintain the temperature of the vehicle at the target temperature. In addition, the present invention may not specifically limit the number of control parameter groups acquired. For example, it can also be three groups, four groups, or five groups.

[0046] If the control parameters obtained are three groups, the first energy consumption value corresponding to the first group of control parameters, the second energy consumption value corresponding to the second group of control parameters, and the third energy consumption value corresponding to the third group of control parameters are obtained, and the minimum value among the first energy consumption value, the second energy consumption value and the third energy consumption value is selected. If the first energy consumption value is the smallest, the first group of control parameters is used as the optimal control parameters. If the second energy consumption value is the smallest, the second group of control parameters is used as the optimal control parameters. If the third energy consumption value is the smallest, the third group of control parameters is used as the optimal control parameters.

[0047] It should be noted that the control parameters include the duty cycle and / or air supply angle of the temperature control device.

[0048] Furthermore, in some embodiments of the present invention, multiple vehicle temperature impact parameter groups are collected, including: collecting one vehicle temperature impact parameter group every first preset time period, and continuously collecting for a second preset time period to obtain multiple vehicle temperature impact parameter groups, wherein the second preset time period is greater than twice the first preset time period.

[0049] Specifically, in this embodiment, a vehicle temperature influence parameter group is collected every first preset time, and the second preset time is continuously collected to obtain multiple vehicle temperature influence parameter groups, wherein the second preset time is greater than twice the first preset time. For example, the first preset time may be ten seconds, the second preset time may be one minute, a vehicle temperature influence parameter group is collected every ten seconds, and the collection is continued for one minute to obtain six vehicle temperature influence parameter groups. In addition, the present invention may not specifically limit the values ​​of the first preset time and the second preset time.

[0050] Furthermore, in some embodiments of the present invention, the average value of each vehicle temperature influencing parameter is calculated, including: after collecting a group of vehicle temperature influencing parameters every first preset time period, using a moving average calculation method to update the average value of each vehicle temperature influencing parameter.

[0051] Specifically, in this embodiment, after collecting a vehicle temperature influencing parameter group every first preset time, the average value of each vehicle temperature influencing parameter is updated using a moving average calculation method, and the calculation formula is as follows:

[0052] T i平 =((i-1)×T (i-1)平 +T i )÷i;

[0053] Among them, T i is the value of the i-th data, i.e., a newly collected vehicle impact parameter value, T (i-1)平 is the average of the first i-1 data points, formula (i-1)×T (i-1)平 Calculate the sum of the first i-1 data, plus T i , we can get the sum of the first i data, and divide the sum of the first i data by i to get the new average value T i平 , and then each time a new vehicle influencing parameter value is received, the formula can be used to quickly and accurately update the average value of each vehicle temperature influencing parameter.

[0054] Further, in some embodiments of the present invention, Figure 2 As shown, multiple vehicle temperature influencing parameters are fused according to the target temperature, average value and weight coefficient interval to determine multiple groups of control parameters of the temperature control device in the vehicle, including:

[0055] S201, determining a plurality of weight coefficient groups according to the target temperature and the weight coefficient interval, each weight coefficient group including a weight coefficient of each vehicle temperature influencing parameter.

[0056] Specifically, in this embodiment, when the vehicle temperature influencing parameters include obtaining the in-vehicle temperature, in-vehicle humidity, outside air pressure, outside wind speed, and outside solar radiation intensity, a plurality of weight coefficient groups can be determined according to the target temperature and the weight coefficient interval of each vehicle temperature influencing parameter by using experimental verification, statistical analysis, or machine learning. For example, three weight coefficient groups are determined, and the first weight coefficient group includes a weight coefficient A1 for the in-vehicle temperature, a weight coefficient B1 for the in-vehicle humidity, a weight coefficient C1 for the outside air pressure, a weight coefficient D1 for the outside wind speed, and a weight coefficient D2 for the outside solar radiation. The first weight coefficient group includes the weight coefficient E1 of the indoor temperature, the weight coefficient B2 of the indoor humidity, the weight coefficient C2 of the outdoor air pressure, the weight coefficient D2 of the outdoor wind speed and the weight coefficient E2 of the outdoor solar radiation intensity. The third weight coefficient group includes the weight coefficient A3 of the indoor temperature, the weight coefficient B3 of the indoor humidity, the weight coefficient C3 of the outdoor air pressure, the weight coefficient D3 of the outdoor wind speed and the weight coefficient E3 of the outdoor solar radiation intensity. In addition, the present invention may not specifically limit the number of multiple weight coefficient groups. It should be noted that the sum of the weight coefficients of the indoor temperature, the indoor humidity, the outdoor air pressure, the outdoor wind speed and the outdoor solar radiation intensity of each weight coefficient group is equal to 1, that is, A1+B1+C1+D1+E1=1, A2+B2+C2+D2+E2=1, and A3+B3+C3+D3+E3=1.

[0057] S202, calculating the product between the average value of each vehicle temperature influencing parameter and each weight coefficient group to obtain multiple groups of control parameters.

[0058] Specifically, in this embodiment, when the control parameter is the duty cycle of the temperature control device, and the vehicle temperature influencing parameters include obtaining the in-vehicle temperature, in-vehicle humidity, outside air pressure, outside wind speed, and outside solar radiation intensity, multiple vehicle temperature influencing parameter groups are collected, and the average in-vehicle temperature, the average in-vehicle humidity, the average outside air pressure, the average outside wind speed, and the average outside solar radiation intensity are calculated. The number of weight arrays is three, and the first weight coefficient group includes the weight coefficient A1 of the in-vehicle temperature, the weight coefficient B1 of the in-vehicle humidity, and the weight coefficient B2 of the outside air pressure. The first group of control parameters is calculated as follows: the first group of control parameters = average value of indoor temperature * weight coefficient A1 of indoor temperature + average value of indoor humidity * weight coefficient B1 of indoor humidity + average value of outdoor pressure * weight coefficient C1 of outdoor pressure + average value of outdoor wind speed * weight coefficient D1 of outdoor wind speed + average value of outdoor solar radiation * weight coefficient E1 of outdoor solar radiation intensity. Similarly, the second group of control parameters and the third group of control parameters can be calculated. In addition, the present invention may not specifically limit the number of weight arrays. For example, the number of weight arrays may be five, six, or seven.

[0059] Further, in some embodiments of the present invention, Figure 3 As shown, after controlling the temperature control device according to the optimal control parameters, the method further includes:

[0060] S301, continuously collecting a vehicle temperature impact parameter group.

[0061] Specifically, in this embodiment, the vehicle temperature influencing parameters include in-vehicle environmental parameters and out-vehicle environmental parameters, wherein the in-vehicle environmental parameters include in-vehicle temperature and in-vehicle humidity, and the out-vehicle environmental parameters include out-vehicle air pressure, out-vehicle wind speed and out-vehicle solar radiation intensity. The in-vehicle temperature can be continuously collected through a temperature sensor, the in-vehicle humidity can be continuously collected through a humidity sensor, the out-vehicle air pressure can be continuously collected through a pressure sensor, the out-vehicle wind speed can be continuously collected through a wind speed sensor, and the out-vehicle solar radiation intensity can be continuously collected through a solar radiation intensity sensor. For example, the in-vehicle temperature, in-vehicle humidity, out-vehicle air pressure, out-vehicle wind speed and out-vehicle solar radiation intensity can be collected every ten seconds and continuously for one minute, thereby respectively obtaining an in-vehicle temperature parameter group, an in-vehicle humidity parameter group, an out-vehicle air pressure parameter group, an out-vehicle wind speed parameter group and an out-vehicle solar radiation intensity parameter group, and these parameter groups are used as multiple vehicle temperature influencing parameter groups.

[0062] S302: When the change amount of at least one vehicle temperature influencing parameter is greater than a preset change threshold, the optimal control parameter is updated.

[0063] Specifically, in this embodiment, when the change in at least one parameter of the indoor temperature, indoor humidity, outdoor air pressure, outdoor wind speed and outdoor solar radiation intensity is greater than a preset change threshold, the average value of each vehicle temperature influencing parameter is recalculated, and the weight coefficient interval of each vehicle temperature influencing parameter is obtained, and the multiple vehicle temperature influencing parameters are fused according to the target temperature, the average value and the weight coefficient interval to determine multiple groups of control parameters of the temperature control device in the vehicle and the energy consumption value corresponding to each group of control parameters, the optimal control parameters are determined from the multiple groups of control parameters according to the energy consumption value corresponding to each group of control parameters, the update of the optimal control parameters is completed, and the temperature control device is controlled according to the updated optimal control parameters to maintain the temperature of the vehicle at the target temperature.

[0064] Further, in some embodiments of the present invention, the control parameters include a duty cycle and / or an air supply angle of the temperature control device. In addition, the present invention may not specifically limit the types of temperature control parameters.

[0065] In summary, according to the vehicle temperature control method of the embodiment of the present invention, by collecting multiple vehicle temperature influencing parameter groups and the target temperature of the vehicle, calculating the average value of each vehicle temperature influencing parameter, and obtaining the weight coefficient interval of each vehicle temperature influencing parameter, the multiple vehicle temperature influencing parameters are fused according to the target temperature, the average value and the weight coefficient interval to determine multiple groups of control parameters of the temperature control device in the vehicle and the energy consumption value corresponding to each group of control parameters, thereby determining the optimal control parameters from the multiple groups of control parameters according to the energy consumption value corresponding to each group of control parameters, and controlling the temperature control device according to the optimal control parameters to maintain the temperature of the vehicle at the target temperature. In this way, the system response speed can be significantly improved, the system energy consumption can be reduced, and the temperature adjustment accuracy can be improved, thereby improving the user's driving experience.

[0066] Based on the vehicle temperature control method proposed in the aforementioned embodiment of the present invention, the embodiment of the present invention further proposes a computer-readable storage medium, on which a vehicle temperature control program is stored. When the program is executed by a processor, the vehicle temperature control method of the aforementioned embodiment of the present invention is implemented.
