[0050] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] The heat source for heat pumps in vehicle thermal management generally comes from the low-temperature heat absorption of the external evaporator and the waste heat recovery of the battery heat exchanger. Currently, existing vehicles typically recover waste heat through methods such as exhaust gas waste heat recovery, engine cooling water waste heat recovery, and brake energy recovery. However, when recovering waste heat through these methods, the ambient temperature and interior temperature of the vehicle are generally not taken into account. As a result, the thermal management energy consumption is high and the heating efficiency is low when the vehicle performs thermal management through waste heat recovery.

[0053] To address the aforementioned issues, the vehicle control method provided in this application can determine whether to heat the vehicle based on the ambient temperature and the vehicle interior temperature. Furthermore, when the ambient temperature and the vehicle interior temperature are higher than a second preset temperature, waste heat recovery from the driver's cabin can be performed. This effectively utilizes the waste heat from the driver's cabin, thereby improving the heating efficiency in the thermal management process.

[0054] The vehicle control method provided in this application can be executed by a server. The server can be a mobile phone, tablet, computer, in-vehicle computer, or other devices. This embodiment does not impose any particular restrictions on the implementation method of the execution subject, as long as the execution subject can obtain the ambient temperature and interior temperature of the vehicle; heat the interior of the vehicle based on the ambient temperature and interior temperature; and recover waste heat from the driver's cabin when the ambient temperature or interior temperature is higher than a second preset temperature, thus performing thermal management of the vehicle.

[0055] Thermal management refers to the dynamic management of heat within the vehicle, which can manage the heat flow of the entire vehicle in an energy-efficient manner (including the heating and cooling management of the battery, motor, electronic control, and passenger compartment), effectively extending the driving range of electric vehicles in winter and summer.

[0056] Vehicle waste heat recovery refers to the process of recovering and converting the waste heat generated during vehicle operation into energy through heat exchange technology, thereby improving the energy efficiency of vehicles.

[0057] Figure 1 This is a flowchart illustrating the vehicle control method provided in an embodiment of this application. The executing entity of this method can be a server or other servers; this embodiment does not impose any particular limitations. Figure 1 As shown, the method may include:

[0058] S101. Obtain the ambient temperature and interior temperature of the vehicle.

[0059] Ambient temperature can refer to the environment in which the vehicle is located.

[0060] The interior temperature of a vehicle can refer to the temperature inside the vehicle. This interior can include the battery compartment, the engine compartment, or the rest of the car's cabin.

[0061] Methods for obtaining the ambient temperature and interior temperature of a vehicle may include detection by temperature sensors located outside and inside the vehicle. In this embodiment, the ambient temperature and interior temperature of the vehicle can be determined by the vehicle's air conditioning system.

[0062] S102. Heating the interior of the vehicle based on the ambient temperature and the interior temperature.

[0063] Heating the interior of a vehicle can refer to heating the interior through a heat pump system, which includes the air conditioning unit, compressor, water-cooled condenser, thermal management module, chiller (refrigeration equipment, including condenser and evaporator), and HVCH (heater).

[0064] In this embodiment of the application, the method for heating the interior of a vehicle based on the ambient temperature and the interior temperature includes:

[0065] When the ambient temperature is between the first preset temperature and the second preset temperature, or when the ambient temperature is between the second preset temperature and the third preset temperature and the interior temperature is higher than the second preset temperature, or when the ambient temperature is lower than the third preset temperature and the interior temperature is higher than the second preset temperature,

[0066] The heater and condenser are controlled to heat the interior of the vehicle, wherein the first preset temperature is higher than the second preset temperature, and the second preset temperature is higher than the third preset temperature.

[0067] The first preset temperature being higher than the second preset temperature, and the second preset temperature being higher than the third preset temperature, can be any preset temperature, or it can be set according to the characteristics of the vehicle during actual use. For example, the first preset temperature can be based on the temperature required by the people inside the vehicle, such as 15℃; the second preset temperature can be based on the temperature at which the vehicle's heat pump system heats the interior, such as -10℃; and the third preset temperature can be determined based on the characteristics of the vehicle's coolant. For example, if the coolant can be used normally at -20℃, then the third preset temperature can be -20℃.

[0068] A heater can refer to a high-pressure liquid heater, which is a heat exchanger used in automotive air conditioning systems. It provides warmth by passing high-pressure refrigerant into the heater, heating it, and transferring the heat to the air inside the vehicle.

[0069] A condenser is a component used in automotive air conditioning systems to condense water vapor in the air into liquid water, thereby reducing humidity. Condensers are typically used in conjunction with evaporators to maintain a comfortable temperature and humidity inside the vehicle. In this embodiment, controlling the condenser to heat the vehicle's interior can be achieved by activating the electric compressor and condenser fan, causing the condenser to release heat into the vehicle.

[0070] In this embodiment of the application, the method for heating the interior of a vehicle based on the ambient temperature and the interior temperature may include:

[0071] When the ambient temperature is lower than the third preset temperature and the interior temperature is lower than the second preset temperature, the coolant in the vehicle's air conditioning system is heated to preheat the vehicle. The third preset temperature is lower than the second preset temperature.

[0072] Detect the coolant temperature;

[0073] When the coolant temperature is higher than the third preset temperature, the interior of the vehicle is heated.

[0074] Coolant temperature refers to the temperature of the coolant, which can be obtained from a sensor installed on the water circuit.

[0075] When the ambient temperature is lower than the third preset temperature, it indicates that the coolant cannot be used normally. Therefore, the coolant needs to be heated to increase its temperature, so that other equipment in the heat pump, such as the air conditioning unit, can be used. At the same time, when the coolant temperature is increased, the coolant can also preheat the vehicle, thereby increasing the temperature inside the vehicle.

[0076] When the coolant temperature is higher than the third preset temperature, the interior of the vehicle can be heated by a heat pump.

[0077] In this embodiment, the third preset temperature can be -20℃, and the second preset temperature can be -10℃. Specifically, in this embodiment, when the ambient temperature is lower than the third preset temperature and the vehicle interior temperature is lower than the second preset temperature, heating the coolant in the vehicle's air conditioning system to preheat the vehicle includes:

[0078] When the ambient temperature is lower than the third preset temperature and the vehicle's interior temperature is lower than the second preset temperature, the vehicle's heater is turned on and the motor is locked to heat the coolant in order to preheat the vehicle's interior.

[0079] Motor stall refers to a situation where a motor, due to various reasons, fails to rotate normally or its rotation is obstructed during operation, causing a sharp increase in motor current, even exceeding the rated current, leading to motor overheating. In this embodiment, since the ambient temperature is lower than the third preset temperature, indicating that the current ambient temperature is too low, heating the coolant by causing the motor to stall can effectively prevent motor overheating and quickly heat the coolant.

[0080] In this embodiment of the application, heating the vehicle interior when the coolant temperature is higher than a third preset temperature includes:

[0081] When the coolant temperature is higher than the third preset temperature, control the motor to exit the stall state;

[0082] After the motor is disengaged from the stall, the condenser is turned on to heat the interior of the vehicle.

[0083] When the coolant temperature is higher than the third preset temperature, the heating effect of the coolant is reduced, which may cause the motor to overheat. Therefore, the motor is controlled to exit the stall mode.

[0084] Heating the vehicle's interior by turning on the condenser can be achieved by turning on the electric compressor, turning on the condenser fan, and opening the damper connecting the condenser to the vehicle's interior. In this embodiment, heating the vehicle's interior based on the ambient temperature and the interior temperature includes:

[0085] When the ambient temperature is between the second and third preset temperatures and the vehicle's interior temperature is lower than the second preset temperature, the heater and condenser are turned on to heat the vehicle's interior. The second preset temperature is higher than the third preset temperature.

[0086] The third preset temperature can be -20℃, and the second preset temperature can be -10℃. S103. When the ambient temperature or the interior temperature of the vehicle is higher than the second preset temperature, waste heat is recovered from the driver's cabin inside the vehicle to perform thermal management of the vehicle.

[0087] The second preset temperature can be a temperature suitable for the operation of each device in the heat pump. In this embodiment, the second preset temperature can be -10℃. When the ambient temperature or the interior temperature of the vehicle is higher than the second preset temperature, waste heat recovery from the driver's cabin for vehicle thermal management can be performed by turning on the evaporator fan, turning off the external circulation, and then turning on the evaporator to absorb heat from the driver's cabin for waste heat recovery.

[0088] In this embodiment of the application, when the ambient temperature or the interior temperature of the vehicle is higher than the second preset temperature, recovering waste heat from the driver's cabin to perform thermal management of the vehicle may include:

[0089] When the ambient temperature and the interior temperature of the vehicle are higher than the second preset temperature, the vehicle's external air circulation will be turned off.

[0090] After the external air circulation is turned off, the evaporator is activated to recover residual heat from the passenger compartment for vehicle thermal management.

[0091] External circulation refers to the process in a vehicle's air conditioning system where fresh air from outside is introduced into the vehicle while air inside is expelled from the vehicle, thus maintaining a fresh and comfortable environment inside the car.

[0092] An evaporator can be used to convert refrigerant from a liquid to a gaseous state, absorbing heat from the vehicle's interior and thus lowering the interior temperature. Simultaneously, the evaporator can also be used for waste heat recovery, transferring waste heat from the vehicle's interior to a heat pump, enabling the heat pump to manage the vehicle's thermal system.

[0093] In this embodiment of the application, after shutting off the external air circulation and starting the evaporator to recover waste heat from the vehicle's cabin, the method further includes:

[0094] Obtain the evaporator outlet temperature and the vehicle's current ambient temperature;

[0095] Compare the outlet temperature with the current ambient temperature;

[0096] If the outlet temperature is higher than the current ambient temperature, the evaporator is controlled to transfer the waste heat of the cabin into the vehicle for thermal management.

[0097] If the outlet temperature is lower than the current ambient temperature, the evaporator will be controlled to expel the residual heat from the cockpit to the outside of the vehicle.

[0098] Controlling the transfer of heat from the evaporator to the vehicle interior can refer to the process of recovering and utilizing waste heat from the cockpit.

[0099] Controlling the evaporator's heat discharge to the outside of the vehicle can refer to a situation where the heat in the passenger compartment is high, causing the outlet temperature to exceed the ambient temperature. This allows for the recovery and reuse of waste heat from the passenger compartment, which can then be used for vehicle thermal management. Conversely, controlling the evaporator's heat discharge to the outside of the vehicle can also refer to a situation where the heat in the passenger compartment is too low to be recovered, thus requiring the evaporator to discharge heat to the outside of the vehicle.

[0100] The vehicle control method provided in this application embodiment can recover waste heat from the driver's cabin based on the ambient temperature and the interior temperature, thereby making full use of the waste heat in the driver's cabin and improving thermal management efficiency. Simultaneously, by setting a first preset temperature, a second preset temperature, and a third preset temperature, and through corresponding preheating and heating methods, the application range of the heat pump can be increased, and the heating power consumption in extremely cold weather can be reduced.

[0101] Figure 2 This is a flowchart illustrating another vehicle control method provided in an embodiment of this application. The executing entity of this method can be an onboard computer; however, this embodiment does not impose any particular limitation. Figure 2 As shown, the method may include:

[0102] S201, Air conditioning is turned on in AUTO N mode;

[0103] S202, The vehicle controller detects the ambient temperature and the interior temperature of the vehicle;

[0104] S203. Determine the vehicle's heating mode based on the ambient temperature and the vehicle interior temperature. The heating modes include ultra-low temperature heating mode, cockpit waste heat recovery heating mode one, low temperature heating mode, and cockpit waste heat recovery heating mode two.

[0105] S204. When the ambient temperature is below -20 degrees Celsius and the interior temperature is below -10 degrees Celsius, control the vehicle to be in ultra-low temperature heating mode.

[0106] The control of the vehicle in ultra-low temperature heating mode can be achieved as follows: HVCH is activated to heat the coolant in the water circuit. The heat is then passed through the chiiller (battery cooler) to heat the refrigerant in the air conditioner. At the same time, the motor stalling regenerative braking is activated to quickly raise the coolant temperature. When the coolant temperature is above -20°C, the motor stalling regenerative braking is deactivated, the electric compressor is activated, the condenser fan is activated, and the air duct 1 and air duct 6 are closed while air duct 2 is opened, so that the condenser releases heat to the vehicle interior to achieve the heating function, thereby heating the vehicle interior.

[0107] S205. When the vehicle controller detects that the interior temperature rises above -10 degrees Celsius, the vehicle switches from the ultra-low temperature heating mode to the cockpit waste heat recovery heating mode one.

[0108] One of the methods for controlling the vehicle to be in the cockpit waste heat recovery heating mode is as follows: the evaporator fan is turned on, the vehicle controller controls the damper 5 to close the external circulation, the vehicle controller turns on the evaporator to absorb heat from the cockpit and recover waste heat from the cockpit, and at the same time the vehicle controller reduces the power of HVCH according to a preset algorithm. Specifically, when the evaporator outlet air temperature is higher than the ambient temperature, the vehicle controller controls the dampers 3 and 4 of the air duct to close and the damper 6 to open, thereby performing thermal management of the vehicle. When the evaporator outlet temperature is lower than the ambient temperature, the vehicle controller controls the dampers 3 and 6 of the air duct to close and the damper 4 to open, thereby discharging the recovered heat to the outside of the vehicle.

[0109] S206. When the ambient temperature is between -20 degrees Celsius and -10 degrees Celsius, and the interior temperature of the vehicle is below -10 degrees Celsius, control the vehicle to be in low-temperature heating mode.

[0110] The method of controlling the vehicle to be in low-temperature heating mode can be as follows: control the heater to work, and the heater power decreases as the temperature inside the vehicle rises. The electric compressor is turned on, the condenser fan is turned on, the damper 1 and damper 6 are closed, damper 2 is opened, and the condenser releases heat to achieve the heating function. As a result, the temperature inside the vehicle continues to rise over time.

[0111] S207. When the vehicle controller detects that the interior temperature rises to above -10 degrees Celsius, the vehicle switches from the ultra-low temperature heating mode to the cabin waste heat recovery heating mode one.

[0112] S208. When the ambient temperature is below -20 degrees Celsius and the interior temperature is above -10 degrees Celsius; when the ambient temperature is between -20 degrees Celsius and -10 degrees Celsius and the interior temperature is above -10 degrees Celsius; when the ambient temperature is between -10 degrees Celsius and N degrees Celsius, control the vehicle to be in the second mode of waste heat recovery heating in the driver's cabin.

[0113] The second mode of controlling the vehicle to be in the cockpit waste heat recovery heating mode can be as follows: the electric compressor is turned on, the condenser fan is turned on, the damper 1 of the control air duct is closed, the damper 2 is opened, so that the evaporator is connected to the cabin, the evaporator fan is turned on, the algorithm controls the damper 5 to close the external circulation, the vehicle controller turns on the evaporator to absorb heat from the cockpit and perform cockpit waste heat recovery. When the evaporator outlet air temperature is higher than the ambient temperature, the vehicle controller controls the dampers 3 and 4 to close and the damper 6 to open. When the evaporator outlet temperature is lower than the ambient temperature, the vehicle controller controls the dampers 3 and 6 to close and the damper 4 to open, while reducing the power of the HVCH (heater).

[0114] N℃ can refer to the normal temperature set inside the vehicle.

[0115] S209. When the ambient temperature is above or equal to N℃, AUTO is in non-heating mode.

[0116] Figure 3 This is a schematic diagram illustrating another vehicle control method provided in an embodiment of this application. Figure 3 As shown, the scenario includes: an air duct system, wherein the air duct system consists of two air ducts. The first air duct houses the evaporator, and this air duct can be opened or closed for external circulation via damper 5, connected to the outside via damper 4, and connected to the cockpit via damper 3. The second air duct houses the condenser, and this air duct can be connected to the cockpit via damper 2, and connected to the outside via damper 1. The two air ducts are connected by damper 6.

[0117] Therefore, the vehicle control method provided in this application embodiment can increase the application range of the heat pump when heating at low temperatures, that is, it can be used in an environment of -30℃, further reducing the power consumption for heating in winter, greatly improving the pure electric range of new energy vehicles in winter, and increasing the heat source, improving efficiency, and further improving the winter range. The heat can come from three aspects: the stalled heat of the electric motor, the heating of the water circuit by the high-pressure heater, and the recovery of waste heat from the passenger compartment.

[0122] In this embodiment of the application, the heating module 402 can also be specifically used for:

[0133] In this embodiment of the application, the heating module 402 can also be specifically used for:

[0134] When the coolant temperature is higher than the third preset temperature, control the motor to exit the stall state;

[0135] After the motor is disengaged from the stall, the condenser is turned on to heat the interior of the vehicle.

[0137] When the ambient temperature is between the second and third preset temperatures and the vehicle's interior temperature is lower than the second preset temperature, the heater and condenser are turned on to heat the vehicle's interior. The second preset temperature is higher than the third preset temperature.

[0138] In this embodiment of the application, the waste heat recovery module 403 can also be specifically used for:

[0139] When the ambient temperature and the interior temperature of the vehicle are higher than the second preset temperature, the vehicle's external air circulation will be turned off.

[0140] After the external air circulation is turned off, the evaporator is activated to recover residual heat from the passenger compartment for vehicle thermal management.

[0141] In this embodiment of the application, the waste heat recovery module 403 can also be specifically used for:

[0142] Obtain the evaporator outlet temperature and the vehicle's current ambient temperature;

[0143] Compare the outlet temperature with the current ambient temperature;
