[0056] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0057] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0058] Figure 1 It is a scenario schematic diagram of a vehicle control method provided in an embodiment of the present application.

[0059] For example, Figure 1 As shown, the cockpit 110 of the vehicle 100 includes multiple components; for example, a steering wheel 120, a seat 130 and an air conditioner 140. By turning on the temperature control functions of the steering wheel 120, the seat 130 and the air conditioner 140, the comfort of the user in the vehicle can be improved.

[0060] It should be noted that the temperature control function of the components in the vehicle in the related art requires manual adjustment by the user; for example, the air conditioning adjustment parameters require manual adjustment by the user; however, the manual adjustment of the temperature control function parameters has a lag, which not only makes it difficult to ensure the comfort of the users in the vehicle, but also may cause excessive consumption of the vehicle's energy. In view of this, in order to improve the riding comfort of the users in the vehicle and reduce the energy consumption of the vehicle, the present application provides a vehicle control method, a vehicle control device, a vehicle and a storage medium, which can reduce the energy consumption of the vehicle while improving the comfort of the users in the vehicle.

[0061] Figure 2 It is a schematic diagram of a framework of a vehicle control system provided in an embodiment of the present application.

[0062] It is understandable that the target component includes any one of an air conditioner, a steering wheel, and a seat. This embodiment is described by taking the target component as an air conditioner as an example.

[0063] For example, Figure 2 As shown, when the temperature control functions of the air conditioners in the vehicle are all in the turned-on state, the temperature control parameters of the air conditioners are adjusted through the vehicle control system 200, thereby improving the riding comfort of users in the vehicle while reducing the energy consumption of the vehicle.

[0064] Specifically, the temperature inside the car and the temperature outside the car are collected by sensors, and the temperature inside the car and the temperature outside the car are input into the initialization module 201. The initialization module 201 determines the current control parameters of the air conditioner according to the temperature inside the car and the temperature outside the car, and controls the air conditioner to operate according to the current control parameters through the execution module 202.

[0065] It can be understood that based on the outside temperature and the inside temperature, it can be determined whether the current actual demand is to increase the temperature or to decrease the temperature; therefore, based on the outside temperature and the inside temperature, the current control parameters of the temperature control function of the target component can be determined.

[0066] The current control parameters of the air conditioner (heater power, blower gear, blowing mode and circulation mode) are input into the first human body air environment calculation module 203, and the first human body air environment calculation module 203 predicts the ambient temperature (air flow rate, air humidity and air temperature) of various parts of the human body through the current control parameters of the air conditioner.

[0067] In one example, the ambient temperature of each part of the human body is input into the first human physiological calculation module 204, and the first human physiological calculation module 204 predicts the surface temperature of each part of the human body, the internal temperature of the human body and the temperature change rate of the surface temperature of each part of the human body.

[0068] In another example, the thermal resistance of human clothing is determined according to the ambient temperature, and the thermal resistance of the clothing and the ambient temperature of each part of the human body are input into the first human physiological calculation module 204. The first human physiological calculation module 204 predicts the surface temperature of each part of the human body, the internal temperature of the human body, and the temperature change rate of the surface temperature of each part of the human body.

[0069] Furthermore, the surface temperature of each part of the human body, the internal temperature of the human body and the temperature change rate of the surface temperature of each part of the human body are input into the first human thermal comfort calculation module 205, and the local comfort parameters of each part of the human body and the overall comfort parameters of the human body are obtained through the prediction of each part of the human body (the target comfort parameters include the local comfort parameters and the overall comfort parameters).

[0070] The feasible solution calculation module 206 selects candidate control parameters according to the local comfort parameters of each part of the human body, the overall comfort parameters of the human body and the preset control parameters. For example, if the current thermal sensation state of the human body is determined to be cold according to the local comfort parameters of each part of the human body and the overall comfort parameters of the human body, the candidate control parameters can make the thermal sensation of the human body tend to a comfortable state.

[0071] For each candidate control parameter, each candidate control parameter (control parameter of the air conditioner) is input into the second human body air environment calculation module 207 to predict the predicted ambient temperature (predicted air flow rate, predicted air humidity and predicted air temperature) of the human body.

[0072] Exemplarily, the predicted ambient temperature of the human body corresponding to each candidate control parameter is input into the second human physiological heat calculation module 209, and the surface temperature of each part of the human body, the internal temperature of the human body, and the temperature change rate of the surface temperature of each part of the human body are predicted. Alternatively, the thermal resistance of the clothing and the predicted ambient temperature of the human body are input into the second human physiological heat calculation module 209, and the surface temperature of each part of the human body, the internal temperature of the human body, and the temperature change rate of the surface temperature of each part of the human body are predicted.

[0073] The surface temperature of each part of the human body, the internal temperature of the human body and the temperature change rate of the surface temperature of each part of the human body are input into the second human body thermal comfort calculation module 210, and the target comfort parameters of the human body (the overall comfort parameters of the human body) are predicted by the second human body thermal comfort calculation module 210.

[0074] In addition, each candidate control parameter (control parameter of the air conditioner) is input into the energy calculation module 208 to predict the target energy consumption corresponding to each candidate control parameter. Then, the optimal solution calculation module 211 selects the target control parameter from the candidate control parameters according to the target comfort parameter and the target energy consumption corresponding to each candidate control parameter, and controls the air conditioner, the steering wheel and the seat to operate the temperature control function according to the target control parameter through the execution module 202.

[0075] The above technical scheme can improve the convenience of adjusting the control parameters of the target components in the vehicle by selecting the target control parameters to operate the target components through the target comfort parameters corresponding to the candidate control parameters of the target components in the vehicle; further, the target control parameters can be determined through the target comfort parameters and target energy consumption corresponding to each candidate control parameter, and the target control parameters can be selected from the dual dimensions of comfort and vehicle energy consumption, which can ensure the accuracy of the target control parameters, thereby reducing the vehicle energy consumption while improving the comfort of users in the vehicle.

[0076] Figure 3 It is a schematic flow chart of a vehicle control method provided in an embodiment of the present application.

[0077] For example, Figure 3 The method shown can be executed by a vehicle controller or chip of the vehicle.

[0078] For example, Figure 3 As shown, the method 300 includes the following processes:

[0079] S310: If it is detected that the temperature control function of the target component in the vehicle is in an on state, obtain candidate control parameters of the target component.

[0080] Exemplarily, the target component is any one of an air conditioner, a steering wheel, and a seat. The target component may be an air conditioner, or the target component may be a seat, etc., which is not specifically limited here.

[0081] Exemplarily, the temperature control function of the target component is used to indicate that the comfort of a human body (user) in the vehicle is improved through heating, cooling, ventilation, etc.

[0082] Optionally, the candidate control parameters are at least one group of control parameters, and the at least one group of control parameters includes control parameters corresponding to the target component.

[0083] Exemplarily, the candidate control parameters are used to indicate the control parameters that can be selected by the target component. For example, when the target component is an air conditioner, the candidate control parameters may include component parameters related to air conditioner temperature regulation, such as heater power, blowing mode, and circulation mode.

[0084] In one example, the target component corresponds to a preset control parameter, and when it is detected that the function of the target component in the vehicle is turned on, the preset control parameter is determined as a candidate control parameter. For example, the target component is an air conditioner; the candidate control parameters include control parameter 1 of the air conditioner, control parameter 2 of the air conditioner, and control parameter 3 of the air conditioner.

[0085] Specifically, the control parameter 1 of the air conditioner is: heating condition, heater power is 100%, blower gear 5, defrost mode, and internal circulation; the control parameter 2 of the air conditioner is: heating condition, heater power is 80%, blower gear 4, defrost mode, and internal circulation; the control parameter 3 of the air conditioner is: heating condition, heater power is 50%, blower gear 3, defrost mode, and internal circulation.

[0086] In another example, when the vehicle is powered on, if it is detected that the temperature control function of the target component is in the on state, the current comfort parameters of the human body are determined based on the current control parameters of the temperature control function of the target component. The current comfort parameters are used to indicate the current comfort level of the human body in the vehicle, and candidate control parameters are determined based on the current comfort parameters and the preset control parameters of the target component.

[0087] It should be noted that when any control parameter in the preset control parameters of the target component is selected, it cannot ensure that the comfort of the human body in the vehicle is improved, and the preset control parameters of the target component are screened by the current comfort parameters to obtain candidate control parameters that can improve the comfort of the human body. It can be understood that when any control parameter in the candidate control parameters is selected, the comfort of the human body in the vehicle can be improved, even if the comfort of the human body is higher than the current comfort.

[0088] Optionally, the human body's comfort level can be comfortable, cool, cold, very cold, warm, hot, very hot, etc., and the highest human body comfort level is a comfortable state.

[0089] Exemplarily, the current control parameter of the temperature control function of the target component is used to indicate the current operating parameter of the target component, and the current comfort level of the human body can be determined by the current control parameter of the temperature control function of the target component. It is understandable that as the activation time of the temperature control function of the target component in the vehicle changes, the corresponding comfort parameter of the human body, that is, the corresponding comfort level of the human body will change.

[0090] Exemplarily, the preset control parameters of the target component can be determined according to the vehicle model; for example, when the target component is a seat and the target vehicle model is a first-class vehicle model, the seat heating is at level 2; when the target component is an air conditioner and the target vehicle model is a first-class vehicle model, the air conditioner heater has a maximum power of 100%, a blower at level 3, a defrost mode, an internal circulation, etc.; the preset control parameters can be determined according to actual conditions and are not specifically limited here.

[0091] Exemplarily, the current control parameters of the temperature control function of the target component can be determined according to the environmental parameters of the vehicle. Specifically, if the temperature control function of the target component is detected to be turned on, the outside temperature and the inside temperature of the vehicle are obtained, and the current control parameters of the temperature control function of the target component are determined based on the outside temperature and the inside temperature. It can be understood that based on the outside temperature and the inside temperature, it can be determined whether the current actual demand is to increase the temperature or to decrease the temperature; therefore, the current control parameters of the temperature control function of the target component can be determined based on the outside temperature and the inside temperature.

[0092] For example, the target component is an air conditioner, the air conditioner is in heating gear, and the heater power (or the power of a positive temperature coefficient thermistor, PTC, Positive Temperature Coefficient), blower gear, blowing mode and circulation mode of the air conditioner are determined according to the parking temperature and the outside temperature.

[0093] Specifically, when the outside temperature is less than or equal to -10℃, the air conditioner is in a high-level heating condition, and the air conditioner corresponds to a control signal PTC power of 100%, blower gear 5, defrost mode, and internal circulation; when the outside temperature is greater than -10℃, the air conditioner is in a high-level heating condition, and the air conditioner corresponds to a control signal PTC power of 100%, blower gear 5, defrost mode, and internal circulation; when the outside temperature is greater than -10℃, the temperature inside the car is greater than -10℃, the temperature inside the car is greater than 0℃ and less than or equal to 10℃, the air conditioner is in the second-highest level heating condition, and the air conditioner corresponds to a control signal PTC power of 80%, blower gear 5, defrost mode, and internal circulation; When the outside temperature is greater than -10°C, the temperature inside the car is greater than 10°C and less than or equal to 20°C, the air conditioner is in a medium-level heating condition, and the corresponding control signal of the air conditioner is 50% of the PTC power, the blower is in gear 3, the defrosting mode is full, and the internal circulation is performed; when the outside temperature is greater than -10°C, the temperature inside the car is greater than 20°C and less than or equal to 25°C, the air conditioner is in a low-level heating condition, and the corresponding control signal of the air conditioner is 20% of the PTC power, the blower is in gear 1, the blowing mode is full, and the internal circulation is performed; when the outside temperature is greater than 25°C or the temperature inside the car is greater than 25°C, the air conditioner is in a non-heating condition, and the corresponding control signal of the air conditioner is PTC power is not turned on, and the blower is in gear OFF. Further, after determining the current control parameters of the temperature control function of the target component, the current comfort parameters are determined according to the current control parameters.

[0094] In one example, if the target component is a steering wheel or a seat, the current surface temperature of the target component is determined based on the starting temperature of the target component when the temperature control function is turned on, the target temperature corresponding to each gear of the target component, and the surface temperature of the target component at the last moment. Thus, the current comfort parameters of the human body are predicted based on the current surface temperature of the target component.

[0095] In another example, if the target component is an air conditioner, the environmental parameters (air velocity, air temperature and air humidity) of various parts of the human body are predicted according to the current control parameters (PTC power, blower gear, blowing mode and circulation mode), and the thermal resistance of human clothing is obtained. The thermal resistance of clothing and the environmental parameters of various parts of the human body are input into the first human physiological calculation module, and the surface temperature of various parts of the human body, the internal temperature of the human body and the temperature change rate of the surface temperature of each part are output. The temperature change rate is used to represent the temperature change rate of the surface temperature of the target part of the human body at the current moment and the surface temperature of the target part of the human body at the previous moment.

[0096] Furthermore, the current comfort parameters are determined based on the surface temperature of each part of the human body, the internal temperature of the human body and the temperature change rate, that is, the surface temperature of each part of the human body, the internal temperature of the human body and the temperature change rate are input into the first human thermal comfort calculation module, and the current comfort parameters of the human body are output.

[0097] Optionally, human body parts may include head, chest, abdomen, left upper arm, left lower arm, right upper arm, right lower arm, left thigh, left calf, right thigh, right calf, left foot, right foot, etc. The classification of human body parts can be determined according to actual conditions and is not specifically limited here.

[0098] It can be understood that the first human physiological heat calculation module includes a physiological calculation model, which is a trained calculation model; the first human thermal comfort calculation module includes a comfort calculation model, which is a trained calculation model.

[0099] Optionally, the current comfort parameter may be an overall comfort parameter; or the current comfort parameter may be an overall comfort parameter and a local comfort parameter. The current comfort parameter may be determined according to actual conditions and is not specifically limited herein.

[0100] For example, the current comfort parameter includes a local comfort parameter and an overall comfort parameter. The local comfort parameter represents the comfort parameter of a certain part of the human body, and the overall comfort parameter represents the overall comfort parameter of the human body. The expression of the local comfort parameter can be expressed as follows:

[0101] S pi =f(S i ,S h ,C pi )

[0102] Among them, S pi represents the comfort parameter of body part i, S i represents the body surface temperature at part i, S h Indicates the body's internal temperature (or core temperature), C pi It represents the temperature change rate of part i. According to the surface temperature of part i, the temperature change rate and the internal temperature of the human body, the local comfort parameter of part i can be determined.

[0103] The expression of the overall comfort parameter can be expressed as follows:

[0104] S w =∑S pi *K i

[0105] Among them, S pi represents the comfort parameter of body part i, K i represents the weight coefficient of position i, S w It represents the overall comfort parameter of the human body, which is the cumulative sum of the products of the comfort parameters of each part of the human body and the weight coefficient.

[0106] Exemplarily, the PTC power, blower gear, air outlet mode and circulation mode of the air conditioner are input into the first human body air environment calculation module, and the environmental parameters of various parts of the human body are output. For example, the environmental parameters of various parts of the human body include the air flow rate, air temperature and air humidity around the head; the environmental parameters of various parts of the human body include the air flow rate, air temperature and air humidity around the abdomen, etc. It can be understood that the first human body air environment calculation module includes an environmental calculation model, and the environmental calculation model is a trained model.

[0107] Table 1 is a schematic diagram of thermal resistance of clothing

[0108] Ambient temperature Thermal resistance of clothing -40 1.3 -20 1.2 -10 1.0 0 0.9 10 0.8 20 0.7 30 0.6 40 0.5

[0109] Exemplarily, as shown in Table 1, the ambient temperature of the vehicle is obtained, and the corresponding clothing thermal resistance is determined according to the ambient temperature. The ambient temperature may be the average temperature of the outside temperature and the inside temperature, or the ambient temperature may be the inside temperature, or the ambient temperature may be the outside temperature. The ambient temperature may be determined according to actual conditions and is not specifically limited here.

[0110] It can be understood that the thermal resistance of clothes is used to indicate the thermal insulation performance of clothes, and can reflect the ability of clothes to hinder heat transfer; the thermal resistance of clothes is positively correlated with the thermal insulation performance of clothes. The greater the thermal resistance of clothes, the better the thermal insulation performance of clothes, and the smaller the thermal resistance of clothes, the worse the thermal insulation performance of clothes.

[0111] According to the above technical scheme, if it is detected that the temperature control function of the target component is in the on state, the current comfort parameters of the human body are determined based on the current control parameters of the temperature control function of the target component, and the candidate control parameters are determined based on the current comfort parameters and the preset control parameters of the target component; the candidate control parameters are screened through the current control parameters of the temperature control function of the target component and the preset control parameters of the target component, which can ensure that controlling the target component through any control parameters among the candidate control parameters can make the human body more comfortable, thereby improving the comfort of users in the vehicle and further improving the driving experience of users.

[0112] S320, predicting the target comfort parameters and target energy consumption corresponding to each candidate control parameter.

[0113] Exemplarily, the target comfort parameter is used to indicate the comfort of the human body. The target comfort parameter is used to indicate the overall thermal sensation of the human body; or, the target comfort parameter may include a local comfort parameter and an overall comfort parameter, and the local comfort parameter is used to indicate the comfort parameter of a target part of the human body. The target part is any part of the human body.

[0114] Exemplarily, the target energy consumption is used to indicate the energy consumption of the vehicle after the temperature control function of the target component is turned on according to the candidate control parameters.

[0115] It can be understood that the candidate control parameters include at least one group of control parameters. By predicting the target comfort parameters corresponding to each candidate control parameter, the target control parameters are selected from the target comfort parameters according to the target comfort parameters and target energy consumption of each candidate control parameter in the candidate control parameters.

[0116] Exemplarily, when the target component is a steering wheel, the energy consumption of the steering wheel is determined as the target energy consumption; when the target component is a seat, the energy consumption of the seat is determined as the target energy consumption; when the target component is an air conditioner, the sum of the air conditioner's PTC energy consumption, blower energy consumption, compressor energy consumption, water pump energy consumption and other energy consumption related to air conditioning regulation is determined as the target energy consumption.

[0117] Specifically, the target component is the air conditioner, and the heater energy consumption, blower energy consumption, compressor energy consumption, water pump energy consumption and other energy consumption corresponding to each candidate control parameter are obtained, and the sum of the heater energy consumption, blower energy consumption, compressor energy consumption, water pump energy consumption and other energy consumption related to air conditioning regulation is determined as the target energy consumption.

[0118] In the above technical scheme, the target component is an air conditioner. The target energy consumption corresponding to each candidate control parameter is determined according to the sum of the heater energy consumption, blower energy consumption, compressor energy consumption, water pump energy consumption and other energy consumption related to air conditioning regulation corresponding to each candidate control parameter; by determining the target energy consumption based on the heater energy consumption, blower energy consumption and water pump energy consumption, the accuracy of the target energy consumption can be ensured, and the accuracy of the target control parameters can be improved as much as possible.

[0119] Exemplarily, the target comfort parameters corresponding to the candidate control parameters are determined based on the candidate control parameters of the target component.

[0120] In one example, the target component is an air conditioner, and the environmental parameters of various parts of the human body and the thermal resistance of human clothes corresponding to each candidate control parameter are obtained. Based on the environmental parameters of various parts of the human body and the thermal resistance of clothes, the surface temperature of various parts of the human body, the internal temperature of the human body and the temperature change rate are predicted. Then, based on the surface temperature, internal temperature and temperature change rate of various parts of the human body, the target comfort parameters of each candidate control parameter are determined.

[0121] Optionally, the environmental parameters of the human body may be environmental parameters of various parts of the human body; the environmental parameters of the human body may also be predicted environmental parameters of various parts of the human body, the surface temperature of the steering wheel, and the surface temperature of the seat; of course, the environmental parameters of the human body are environmental parameters in the car. The environmental parameters of the human body may be determined according to actual conditions and are not specifically limited here.

[0122] Exemplarily, the vehicle interior temperature is obtained, and the corresponding clothing thermal resistance is determined according to the vehicle interior temperature. The method for determining the clothing thermal resistance can refer to the aforementioned disclosed embodiments, which will not be described in detail here.

[0123] Exemplarily, the surface temperature of each part of the human body is used to indicate the skin surface temperature of each part of the human body; for example, if the human body part is the left upper arm, the surface temperature of the left upper arm indicates the skin surface temperature of the left upper arm.

[0124] Exemplarily, the body's internal temperature is used to indicate the temperature inside the human body, to indicate the temperature close to the core parts of the human body (such as the chest cavity, abdominal cavity, and central nervous system, etc.), and the body's internal temperature is used to measure the physiological state of the human body.

[0125] Exemplarily, the temperature change rate is used to indicate the change rate between the body surface temperature of each part of the human body at the previous moment and the body surface temperature at the current moment.

[0126] Exemplarily, each candidate control parameter (control parameter of the air conditioner) is input into the second human body air environment calculation module, and the environmental parameters (air flow rate, air humidity and air temperature) of each part of the human body are output. The thermal resistance of the clothes and the environmental parameters of each part of the human body are input into the second human physiological heat calculation module, and the surface temperature of each part of the human body, the internal temperature of the human body and the temperature change rate of each part of the human body are output.

[0127] It can be understood that the second human physiological heat calculation module includes a physiological calculation model, and the physiological calculation model is a trained calculation model.

[0128] Furthermore, the surface temperature of each part of the human body, the internal temperature of the human body and the temperature change rate of each part of the human body are input into the second human thermal comfort calculation module, and the target comfort parameters corresponding to the candidate control parameters are output.

[0129] In the above technical scheme, if the target component is an air conditioner, the environmental parameters of each part are predicted according to each candidate control parameter (control parameters of the air conditioner), so that the accuracy of the target comfort parameters corresponding to each candidate control parameter can be ensured through the environmental parameters of each part of the human body and the thermal resistance of clothes.

[0130] Exemplarily, after determining the surface temperature of various parts of the human body, the internal temperature and the temperature change rate of the surface temperature of each part, the local comfort parameters of the target part are determined based on the surface temperature of the target part, the internal temperature and the temperature change rate corresponding to the target part. The target part is used to indicate any part of the human body; based on the local comfort parameters of various parts of the human body, the target comfort parameters are determined.

[0131] It can be understood that the target comfort parameter is the overall comfort parameter of the human body, and the target comfort parameter is the fusion comfort parameter of the local comfort parameters of various parts of the human body; that is, the target comfort parameter is the comfort parameter obtained by fusing the local comfort parameters of various parts of the human body. The determination method of the target comfort parameter can refer to the determination method of the overall comfort parameter in the aforementioned disclosed embodiment, and will not be repeated here.

[0132] The above technical scheme determines the local comfort parameters of the target part based on the surface temperature of the target part, the internal temperature and the temperature change rate corresponding to the target part, and the target part is used to indicate any part of the human body; the target comfort parameters are determined based on the local comfort parameters of various parts of the human body; the target comfort parameters corresponding to each candidate control parameter are determined through the surface temperature, the internal temperature and the temperature change rate of various parts of the human body, which can ensure the accuracy of the target comfort parameters corresponding to each candidate control parameter, and select the target control parameters based on the target comfort parameters, which can ensure the comfort inside the vehicle when the target component operates with the target control parameters, thereby improving the comfort of users in the vehicle.

[0133] In another example, if the target component is a steering wheel or a seat, the target surface temperature of the target component can be determined based on the candidate control parameters, the comfort parameters of the target part corresponding to the target component can be determined based on the target surface temperature and the thermal resistance of the clothes, and the target comfort parameters of the human body can be determined based on the comfort parameters of the target part.

[0134] Optionally, when the target component is a steering wheel, the target part is a hand; when the target component is a seat, the target part is a buttocks.

[0135] Specifically, the comfort parameters of the target part corresponding to the target component are determined according to the target surface temperature and the thermal resistance of the clothes, the comfort weight of the target part is determined, and the target comfort parameters of the human body are determined according to the comfort parameters of the target part and the comfort weight of the target part.

[0136] In order to distinguish the target surface temperature corresponding to the steering wheel from the target surface temperature corresponding to the seat, the target surface temperature corresponding to the steering wheel is determined as the first surface temperature, and the target surface temperature corresponding to the seat is determined as the second surface temperature.

[0137] Exemplarily, the starting temperature of the steering wheel when the temperature control function of the target component is turned on, the current surface temperature of the steering wheel (the surface temperature determined when determining the candidate control parameters), and the corresponding control parameter (gear) of the steering wheel are obtained, the target temperature corresponding to the gear of the steering wheel is obtained according to the corresponding gear of the steering wheel, the steering wheel deviation temperature between the target temperature and the current surface temperature of the steering wheel is determined, the target temperature corresponding to the steering wheel deviation temperature is determined according to the relationship between the steering wheel deviation temperature and the preset temperature, the sum of the target temperature and the starting temperature is determined as the first surface temperature of the steering wheel, the preset temperature relationship indicates the corresponding relationship between the preset steering wheel deviation temperature and the preset temperature, and the steering wheel deviation temperature can be converted into the steering wheel temperature through the preset temperature relationship.

[0138] For example, the expression for the first surface temperature of the steering wheel can be expressed as follows:

[0139]

[0140] Among them, T f2 represents the first surface temperature of the steering wheel at time t after the temperature control function of the target component is turned on according to the candidate control parameters, T s2 Indicates the starting temperature of the steering wheel when the temperature control function of the target component is turned on, T j2 Indicates the target temperature corresponding to the gear position of the steering wheel, T f Indicates the current surface temperature of the steering wheel; T j2 -T f Indicates steering wheel deviation temperature; It represents the target temperature corresponding to the steering wheel deviation temperature. The target temperature corresponding to the steering wheel deviation temperature is used to indicate the temperature value converted from the temperature change from time 0 to time t.

[0141] Exemplarily, the starting temperature of the seat when the temperature control function of the target component is turned on, the current surface temperature of the seat (the surface temperature determined when determining the candidate control parameters) and the corresponding control parameter (gear) of the seat are obtained, the target temperature corresponding to the gear of the seat is obtained according to the corresponding gear of the seat, the relationship between the target temperature and the preset temperature is determined, the target temperature corresponding to the seat deviation temperature is determined, the sum of the target temperature and the starting temperature is determined as the second surface temperature of the seat, the preset temperature relationship indicates the corresponding relationship between the preset seat deviation temperature and the preset temperature, and the seat deviation temperature can be converted into the seat temperature through the preset temperature relationship.

[0142] For example, the expression for the second surface temperature of the seat can be expressed as follows:

[0143]

[0144] Among them, T z2represents the second surface temperature of the seat at time t after the temperature control function of the target component is turned on according to the candidate control parameters, T s1 Indicates the starting temperature of the seat when the temperature control function of the target component is turned on, T i2 represents the target temperature corresponding to the seat position (the seat position in the candidate control parameter), T z Indicates the current surface temperature of the seat; T i2 -T z Indicates seat deviation temperature; It represents the target temperature corresponding to the seat deviation temperature. The target temperature corresponding to the seat deviation temperature is used to indicate the temperature value converted from the temperature change amount from time 0 to time t.

[0145] S330: Select a target control parameter from candidate control parameters based on the target comfort parameter and the target energy consumption.

[0146] Exemplarily, the target control parameter is used to indicate a control parameter for controlling the operation of a temperature control function of a target component.

[0147] Exemplarily, when the target comfort parameter and the target energy consumption corresponding to each candidate control parameter are determined, the target control parameter is selected from the candidate control parameters based on the target comfort parameter and the target energy consumption of each candidate control parameter.

[0148] In one example, the target comfort parameters and target energy consumption corresponding to each candidate control parameter are predicted, and the comfort weight corresponding to the target comfort parameter and the energy consumption weight corresponding to the target energy consumption are obtained; and the target control parameter is selected from the candidate control parameters based on the target comfort parameter, the comfort weight, the target energy consumption and the energy consumption weight.

[0149] For example, the sum of the comfort weight and the energy consumption weight is 1, and the comfort weight and the energy consumption weight can be determined according to actual needs. If the comfort demand is higher than the energy saving demand, the comfort weight is greater than the energy consumption weight; if the comfort demand is lower than the energy saving demand, the comfort weight is less than the energy consumption weight.

[0150] For example, the comfort weight is 0.7, the energy consumption weight is 0.3, the product of the target comfort parameter and the comfort weight, and the sum of the product of the target energy consumption and the energy consumption weight are determined as the target parameters, and the candidate control parameter corresponding to the parameter with the highest value among the target parameters is determined as the target control parameter.

[0151] In another example, a target vehicle model is obtained, and a target control parameter is selected from candidate control parameters based on the target vehicle model, target comfort parameters, and target energy consumption.

[0152] Exemplarily, a corresponding target selection strategy is determined according to a target vehicle model, and a target control parameter is selected from candidate control parameters according to the target selection strategy, target comfort parameters, and target energy consumption.

[0153] Exemplarily, vehicle models can be divided into first-class models, second-class models and third-class models; the first-class models have the highest comfort requirements, the second-class models have the second highest comfort requirements, and the third-class models have the lowest comfort requirements.

[0154] The above technical solution selects target control parameters from candidate control parameters based on the target vehicle model, target comfort parameters and target energy consumption; determines the target control parameters through the target vehicle model, target energy consumption and target vehicle model three-dimensional data, which can improve the matching degree between the target control parameters and the target vehicle model, thereby improving the comfort of users in the vehicle while reducing the energy consumption of the vehicle.

[0155] Exemplarily, a first preset comfort parameter corresponding to the target vehicle model is determined, a first control parameter is selected from candidate control parameters based on the first preset comfort parameter and the target comfort parameter, and then the control parameter with the smallest target energy consumption among the first control parameters is determined as the target control parameter.

[0156] Exemplarily, the first preset comfort parameter is used to indicate the comfort requirement of the target vehicle model for riding in the vehicle. Since when the comfort parameter is 0, the human body feels comfortable, the absolute value of the first preset comfort parameter is negatively correlated with the comfort requirement. The higher the comfort requirement, the smaller the absolute value of the first preset comfort parameter.

[0157] Exemplarily, the first control parameter is used to indicate a control parameter among candidate control parameters, and the first control parameter includes at least one control parameter.

[0158] The above technical scheme selects the first control parameter from the candidate control parameters according to the first preset comfort parameter and the target comfort parameter, and determines the control parameter with the smallest target energy consumption among the first control parameters as the target control parameter; the first control parameter is first screened from the candidate control parameters according to the comfort requirement of the target vehicle model (the first preset comfort parameter), and then the target control parameter is screened from the first control parameters according to the target energy consumption, so that when the target control parameter operates the temperature control function of the target component, the energy consumption of the vehicle can be reduced while ensuring the comfort of users in the vehicle.

[0159] Exemplarily, the first preset comfort parameter corresponding to the target vehicle type is determined. Specifically, if the target vehicle type is a first type vehicle type, the first preset parameter is determined as the first preset comfort parameter; if the target vehicle type is a second type vehicle type, the second preset parameter is determined as the first preset comfort parameter, and the absolute value of the second preset parameter is greater than the absolute value of the first preset parameter; if the target vehicle type is a third type vehicle type, the third preset parameter is determined as the first preset comfort parameter, and the absolute value of the third preset parameter is greater than the absolute value of the second preset parameter.

[0160] For example, the first preset parameter is 0, the second preset parameter is -0.5, and the third preset parameter is -1.

[0161] In the above technical scheme, when the target vehicle type is a first type of vehicle type, the first preset parameter is determined as the first preset comfort parameter; when the target vehicle type is a second type of vehicle type, the second preset parameter is determined as the first preset comfort parameter; when the target vehicle type is a third type of vehicle type, the third preset parameter is determined as the first preset comfort parameter; since the absolute value of the second preset parameter is greater than the absolute value of the first preset parameter, and the absolute value of the third preset parameter is greater than the absolute value of the second preset parameter, the corresponding preset comfort parameter is determined through the target vehicle type, and thus the target control parameter is screened, which can ensure the matching of the target vehicle type and the target control parameter, thereby improving the comfort of users in the vehicle.

[0162] Exemplarily, a first preset comfort parameter corresponding to a target vehicle model is determined; if a reference comfort parameter exists in the target comfort parameter, and the absolute value of the reference comfort parameter is less than or equal to the absolute value of the first preset comfort parameter, the candidate control parameter corresponding to the reference comfort parameter is determined as the first control parameter; if a reference comfort parameter does not exist in the target comfort parameter, the first control parameter is selected based on the comfort parameter deviation between the target comfort parameter and the first preset comfort parameter.

[0163] Exemplarily, the absolute value of the reference comfort parameter is less than or equal to the absolute value of the first preset comfort parameter. For example, if the first preset parameter is -0.5, the reference comfort parameter may be 0, -0.5 or 0.5.

[0164] In the above technical solution, if there is a reference comfort parameter in the target comfort parameter, the candidate control parameter corresponding to the reference comfort parameter is determined as the first control parameter; if there is no reference comfort parameter in the target comfort parameter, the first control parameter is selected based on the comfort parameter deviation between the target comfort parameter and the first preset comfort parameter; since the absolute value of the reference comfort parameter is less than or equal to the absolute value of the first preset comfort parameter, the candidate control parameter can be screened according to the first preset comfort parameter, thereby ensuring the comfort of users in the vehicle.

[0165] It can be understood that, in order to more clearly describe the selection strategy of the target control parameter, the target overall comfort parameter is described in the following embodiment, and is in the range of [-3, +3]. Among them, the 7 values ​​of -3, -2, -1, 0, +1, +2, +3 correspond to the 7 thermal sensation states of very cold, cold, cool, comfortable, warm, hot, and very hot, respectively.

[0166] In one example, when the target vehicle model is a first type vehicle model (high-end vehicle model), the first preset comfort parameter corresponding to the first type vehicle model is 0, and it is determined whether there is a comfort parameter (absolute value of the comfort parameter) equal to 0 in the target comfort parameters. When there is a comfort parameter equal to 0 in the target comfort parameters, the candidate control parameter corresponding to the comfort parameter equal to 0 in the target comfort parameters is determined as the first control parameter, and the control parameter with the minimum target energy consumption is selected from the first control parameters and determined as the target control parameter. When there is no comfort parameter equal to 0 in the target comfort parameters, the comfort parameter with the minimum comfort parameter deviation from the first preset comfort parameter is determined in the target comfort parameters, and the control parameter corresponding to the comfort parameter is determined as the target control parameter.

[0167] In another example, when the target vehicle type is a second type vehicle type (mid-range vehicle type), the first preset comfort parameter corresponding to the second type vehicle type is -0.5, and it is determined whether there is a comfort parameter with an absolute value less than or equal to 0.5 in the target comfort parameters. When there is a comfort parameter with an absolute value less than or equal to 0.5 in the target comfort parameters, the candidate control parameter corresponding to the comfort parameter with an absolute value less than or equal to 0.5 in the target comfort parameters is determined as the first control parameter, and the control parameter with the minimum target energy consumption is selected from the first control parameters and determined as the target control parameter. When there is no comfort parameter with an absolute value less than or equal to 0.5 in the target comfort parameters (that is, the absolute values ​​of the comfort parameters in the overall comfort parameters are all greater than 0.5), the comfort parameter with the smallest comfort parameter deviation from the first preset comfort parameter in the target comfort parameters is determined, and the control parameter corresponding to the comfort parameter is determined as the target control parameter.

[0168] In another example, when the target vehicle type is a third-category vehicle type (low-end vehicle type), the first preset comfort parameter corresponding to the third-category vehicle type is -1, and it is determined whether there is a comfort parameter with an absolute value less than or equal to 1 in the target comfort parameters. When there is a comfort parameter with an absolute value less than or equal to 1 in the target comfort parameters, the candidate control parameter corresponding to the comfort parameter with an absolute value less than or equal to 1 in the target comfort parameters is determined as the first control parameter, and the control parameter with the minimum target energy consumption is selected from the first control parameters and determined as the target control parameter. When there is no comfort parameter with an absolute value less than or equal to 1 in the target comfort parameters (the absolute values ​​of the comfort parameters in the target comfort parameters are all greater than 1), the comfort parameter with the smallest comfort parameter deviation from the first preset comfort parameter in the target comfort parameters is determined, and the control parameter corresponding to the comfort parameter is determined as the target control parameter.

[0169] S340, based on the target control parameter, controlling the target component to run a temperature control function.

[0170] Exemplarily, when the target control parameter of the target component is determined, the target component in the vehicle is controlled to perform a temperature control function based on the target control parameter.

[0171] For example, if the target component is an air conditioner, the temperature control system of the air conditioner is controlled to operate according to the target control parameters; if the target component is a seat, the temperature control system of the seat is controlled to operate according to the target control parameters.

[0172] According to the above technical scheme, if it is detected that the temperature control function of the target component in the vehicle is in the on state, the candidate control parameters of the target component are obtained, and the target component is any one of the air conditioner, steering wheel and seat; the target comfort parameters and target energy consumption corresponding to each candidate control parameter are predicted, and based on the target comfort parameters and target energy consumption, the target control parameters are selected from the candidate control parameters, and then based on the target control parameters, the target component is controlled to operate the temperature control function; compared with the prior art in which the control parameters of the temperature control function of the component in the vehicle are manually adjusted, the present application selects the target control parameters to operate the target component through the target comfort parameters corresponding to the candidate control parameters of the target component in the vehicle, which can improve the convenience of adjusting the control parameters of the target component in the vehicle; further, the target control parameters are determined through the target comfort parameters and target energy consumption corresponding to each candidate control parameter, and the target control parameters can be selected from the dual dimensions of comfort and vehicle energy consumption, which can ensure the accuracy of the target control parameters, thereby reducing the vehicle energy consumption while improving the comfort of users in the vehicle.

[0177] Exemplarily, heating or cooling is performed through the heater power, blower gear, blowing mode, circulation mode, etc. of the air conditioner, thereby improving the comfort of the human body (user) in the vehicle.

[0178] Exemplarily, when the vehicle is powered on, if it is detected that the temperature control function of the air conditioner is on, the current comfort parameters are determined based on the current control parameters of the temperature control function of the air conditioner, and the current comfort parameters are used to indicate the current comfort level of a human body in the vehicle.

[0179] Exemplarily, the current control parameters of the temperature control function of the air conditioner are used to indicate the current operating parameters of the air conditioner, and the current comfort level of the human body can be determined through the current control parameters of the temperature control function of the air conditioner. It is understandable that as the activation time of the temperature control function of the air conditioner in the vehicle changes, the corresponding comfort parameters of the human body, that is, the corresponding comfort level of the human body will change.

[0180] Exemplarily, if it is detected that the temperature control function of the air conditioner is in an on state, the outside temperature and the inside temperature of the vehicle are obtained, and based on the outside temperature and the inside temperature, the current control parameters of the temperature control function of the air conditioner are determined.

[0181] Furthermore, when determining the current control parameters of the temperature control function of the air conditioner, the current comfort parameters are determined according to the current control parameters, that is, the environmental parameters of various parts of the human body are determined according to the control parameters corresponding to the air conditioner.

[0182] Exemplarily, the PTC power, blower gear, air outlet mode and circulation mode of the air conditioner are input into the first human body air environment calculation module, and the environmental parameters of various parts of the human body are output. For example, the environmental parameters of various parts of the human body include the air flow rate, air temperature and air humidity around the head; the environmental parameters of various parts of the human body include the air flow rate, air temperature and air humidity around the abdomen, etc.

The temperature change rate is used to represent the temperature change rate of the surface temperature of the target part of the human body at the current moment and the surface temperature of the target part of the human body at the previous moment. Further, according to the surface temperature of various parts of the human body, the internal temperature of the human body and the temperature change rate, the current comfort parameter is determined.

[0185] Optionally, the method for determining the current comfort parameter may refer to the aforementioned disclosed embodiment, which will not be described in detail here.

Specifically, the target comfort parameter and the target energy consumption corresponding to each candidate control parameter are predicted, and the target control parameter is selected from the candidate control parameters based on the target comfort parameter and the target energy consumption corresponding to each candidate control parameter.

[0190] Exemplarily, the target energy consumption is used to indicate the energy consumption of the vehicle after the temperature control function of the air conditioner is turned on according to the candidate control parameters.

[0191] Exemplarily, the sum of all energy consumptions related to PTC energy consumption, blower energy consumption, compressor energy consumption, water pump energy consumption and air conditioning temperature regulation is determined as the target energy consumption.

[0192] S404, obtaining a target vehicle model.

[0193] Exemplarily, the target vehicle model corresponding to the vehicle is determined according to the vehicle. The vehicle models can be divided into the first type of vehicle model, the second type of vehicle model and the third type of vehicle model; the first type of vehicle model has the highest comfort requirement, the second type of vehicle model has the second highest comfort requirement, and the third type of vehicle model has the lowest comfort requirement.
