[0041] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Below, the vehicle heating control method and device provided in the embodiments of the present application will be introduced and explained in detail through several specific embodiments.

[0043] In order to improve the utilization efficiency of the electric drive waste heat of new energy vehicles, the power battery of new energy vehicles is usually heated under low temperature conditions to reduce the energy consumption of the vehicle and improve the user's car experience. In the related technology, the way to heat the power battery of new energy vehicles is to heat the power battery through the electric drive waste heat to keep it at a preset temperature.

[0044] However, this heating method is prone to the situation where the battery temperature will be higher than the ambient temperature for a long time when the vehicle is parked and stationary, causing the battery to continue to dissipate heat, resulting in waste heat in the electric drive and energy waste in the power battery.

[0045] To this end, in one embodiment, a vehicle heating control method is provided, which is applied to a control system for controlling the heating of the vehicle. The control system may include a controller, which may be a controller mounted on the vehicle, such as a VCU (Vehicle Control Unit) or MCU (Microcontroller Unit) of the vehicle.

[0046] like Figure 1 As shown, a vehicle heating control method provided by this embodiment includes:

[0047] Step 101, obtaining the current remaining mileage of the vehicle according to the current location and destination of the vehicle;

[0048] Step 102, determining that the current remaining mileage is greater than a preset mileage, heating the power battery of the vehicle by electric drive waste heat until the current remaining mileage of the vehicle decreases to the preset mileage, and switching the electric drive waste heat to heating the passenger compartment of the vehicle;

[0049] The preset mileage is negatively correlated with the heat dissipation efficiency of the power battery.

[0050] In some embodiments, the use of the vehicle's electric drive waste heat to heat the power battery or the passenger compartment can be achieved through the vehicle's heat pump air conditioning system. The heat pump air conditioning system refers to an air conditioning system used to heat the power battery or the passenger compartment using the electric drive waste heat. For example, Figure 2 As shown, the heat pump air conditioning system may include an electric drive 1, a first water pump 2, a second water pump 3, a water valve 4, a cooler 5, an indoor condenser 6, a one-way valve 7, an electronic expansion valve 8, a compressor 9 and an outdoor condenser 10. Among them, the electric drive 1, the first water pump 2, the second water pump 3 and the battery cold plate of the power battery 11 are connected in series through the water valve 4 to achieve heating of the power battery 11 by the waste heat of the electric drive. To heat the passenger compartment by using the waste heat of the electric drive, the electric drive 1, the first water pump 2 and the cooler 5 are connected in series through the water valve 4. After the refrigerant releases heat through the indoor condenser 6, it flows through the one-way valve 7 and the electronic expansion valve 8, and exchanges heat with the electric drive coolant in the cooler 5. The refrigerant after absorbing heat returns to the compressor 9 to achieve heating of the passenger compartment by the waste heat of the electric drive.

[0051] Among them, other components may be connected between any two of the above-mentioned connected components, such as a power supply may be connected between the first water pump 2 and the electric drive 1, and a solenoid valve may be connected between the indoor condenser and the outdoor condenser.

[0052] In some embodiments, when a user uses a vehicle, it can be detected whether the vehicle is in a low temperature condition. If the vehicle is in a low temperature condition, heating control of the vehicle can be started. When heating control of the vehicle is performed, the current position and destination of the vehicle can be obtained according to the navigation map of the vehicle, so as to obtain the current remaining mileage from the current position of the vehicle to the destination according to the current position of the vehicle and the destination.

[0053] After obtaining the current remaining mileage, the current remaining mileage can be compared with the preset mileage. The preset mileage is greater than 0 and can be set according to the heat dissipation efficiency of the power battery. For example, the higher the heat dissipation efficiency of the power battery, the smaller the preset mileage.

[0054] If the current remaining mileage is less than or equal to the preset mileage, it means that the current remaining mileage to the destination is short. At this time, it is detected whether there is a heating demand for the passenger compartment. If so, the passenger compartment is heated by the residual heat of the electric drive. Figure 2As shown, if the current remaining mileage is less than or equal to the preset mileage and there is a heating demand for the passenger compartment, the electric drive 1, the first water pump 2 and the cooler 5 are controlled to be connected through the water valve 4 to heat the passenger compartment with the residual heat of the electric drive. If the current remaining mileage is less than or equal to the preset mileage and there is no heating demand for the passenger compartment, the heating of the power battery and the passenger compartment with the residual heat of the electric drive is stopped.

[0055] If the current remaining mileage is greater than the preset mileage, it means that the current remaining mileage to the destination is long. At this time, it is detected whether the current temperature of the power battery is less than the preset temperature. If the current temperature is greater than or equal to the preset temperature, it means that there is no need to heat the power battery. At this time, the passenger compartment can be heated by the electric drive waste heat, or the power battery and passenger compartment can be heated by the electric drive waste heat. If the current temperature is less than the preset temperature, the vehicle's power battery is heated by the electric drive waste heat until the vehicle's current remaining mileage is reduced to the preset mileage. If there is a need to heat the passenger compartment, the electric drive waste heat is switched to heat the vehicle's passenger compartment. Assuming that the vehicle's heat pump air-conditioning system is Figure 2 As shown, if the current remaining mileage is greater than the preset mileage and there is a need to heat the power battery, the electric drive 1, the first water pump 2, the second water pump 3 and the battery cold plate of the power battery 11 are controlled to be connected through the water valve 4 to heat the power battery with the waste heat of the electric drive, until the current remaining mileage of the vehicle is reduced to the preset mileage, the water valve 4 is controlled to close the passage between the electric drive 1 and the second water pump 3, and the electric drive 1, the first water pump 2 and the cooler 5 are controlled to be connected through the water valve 4 to switch the waste heat of the electric drive to heating the passenger compartment, and stop heating the power battery.

[0056] The current remaining mileage of the vehicle is obtained through the current position and destination of the vehicle. When it is determined that the current remaining mileage is greater than the preset mileage, the power battery of the vehicle is heated by the residual heat of the electric drive until the current remaining mileage of the vehicle is reduced to the preset mileage, and the residual heat of the electric drive is switched to heating the passenger compartment of the vehicle. Before the vehicle stops and is stationary, the residual heat of the electric drive is stopped from being used to heat the power battery in advance, and the residual heat of the electric drive is used to heat the passenger compartment instead, thereby reducing the battery temperature after the vehicle stops and is stationary, reducing the energy waste caused by the continuous heat dissipation of the battery after the vehicle stops and is stationary, and at the same time, the residual heat of the electric drive can be further utilized, thereby improving the energy utilization efficiency of the residual heat of the electric drive.

[0057] To further reduce energy waste, in some embodiments, the preset mileage may be determined according to the starting time of the vehicle's travel;

[0058] Wherein, if the starting time is earlier than the preset time, the preset mileage is determined to be the first preset mileage; if the starting time is later than the preset time, the preset mileage is determined to be the second preset mileage greater than the first preset mileage;

[0059] The preset time is the predicted starting time of the last driving of the vehicle in a day.

[0060] In some embodiments, before comparing the current remaining mileage with the preset mileage, the starting time of the vehicle's travel may be detected to see if it is earlier than the preset time. The starting time of the vehicle's travel refers to the starting time of the vehicle's current travel. The preset time may be determined by obtaining the latest car-use time of each day in the last N days of the user, that is, the starting time of the latest travel, and then determining the average car-use time calculated from each latest car-use time as the preset time. If the latest car-use time of each day in the last three days of the user can be obtained, assuming that they are 7:00 p.m., 8:00 p.m. and 9:00 p.m. respectively, the preset time may be determined to be 8:00 p.m. based on these three latest car-use times. Alternatively, the latest time point among the latest car-use times may be determined as the preset time. If the latest car-use time of each day in the last three days of the user can be obtained, assuming that they are 7:00 p.m., 8:00 p.m. and 9:00 p.m. respectively, the preset time may be determined to be 9:00 p.m. based on these three latest car-use times.

[0061] After determining the preset time, the starting time of the vehicle's travel can be compared with the preset time for expected management to determine whether the user will use the vehicle for the next trip on the same day. If the starting time is earlier than the preset time, it means that the user will use the vehicle for the next trip on the same day. Even if the power battery temperature is high after this parking and rest, it can be beneficial to the user's next trip, and the degree of energy waste is relatively small. At this time, the preset mileage can be determined to be the first preset mileage with a smaller mileage; if the starting time is later than the preset time, it means that this trip is the last trip of the vehicle on the same day. If the power battery temperature is high after this parking and rest, the heat is only used for heat dissipation, resulting in complete waste of energy. At this time, the preset mileage can be determined to be the second mileage greater than the first preset mileage, so as to shut down the heating of the power battery earlier and reduce energy waste.

[0062] After determining the preset mileage, the current remaining mileage can be compared with the preset mileage. If it is determined that the current remaining mileage is greater than the preset mileage, the vehicle's power battery is heated by the electric drive waste heat until the vehicle's current remaining mileage is reduced to the preset mileage, and the electric drive waste heat is switched to heating the vehicle's passenger compartment. Therefore, it is possible to predict whether the vehicle will make the next trip on the same day based on the start time of the vehicle's current trip, so as to adjust the heating mileage of the power battery and passenger compartment by the electric drive waste heat according to the prediction results, further reduce the energy waste caused by continuous heat dissipation of the battery after parking, and improve the energy utilization efficiency of the electric drive waste heat.

[0063] Considering that if the starting time of the vehicle's travel is used to determine the preset mileage, it may happen that although the starting time of the vehicle's travel is early, the vehicle will arrive at the destination late because it is a long-distance trip, and there is no possibility of using the vehicle next time, resulting in a large waste of energy due to the small preset mileage. To this end, in some embodiments, the preset mileage can be determined according to the estimated time when the vehicle arrives at the destination;

[0064] Among them, if the expected time is earlier than the preset time, the preset mileage is determined to be the first preset mileage; if the expected time is later than the preset time, the preset mileage is determined to be the second preset mileage greater than the first preset mileage.

[0065] In some embodiments, before comparing the current remaining mileage with the preset mileage, the estimated time when the vehicle arrives at the destination may be compared with the preset time for expectation management to determine whether the user will use the vehicle for the next trip on the same day. The estimated time when the vehicle arrives at the destination may be determined by electronic navigation.

[0066] If the estimated time is earlier than the preset time, it means that the user will use the vehicle for the next trip on the same day. Even if the temperature of the power battery is high after this parking and resting, it can be beneficial to the user's next trip, and the degree of energy waste is relatively small. At this time, the preset mileage can be determined as the first preset mileage with a smaller mileage; if the estimated time is later than the preset time, it means that this trip is the last trip of the vehicle on the same day. If the temperature of the power battery is high after this parking and resting, the heat is only used for heat dissipation, resulting in a complete waste of energy. At this time, the preset mileage can be determined as the second mileage greater than the first preset mileage, so as to shut down the heating of the power battery earlier and reduce energy waste.

[0067] After determining the preset mileage, the current remaining mileage can be compared with the preset mileage. If it is determined that the current remaining mileage is greater than the preset mileage, the vehicle's power battery is heated by the electric drive waste heat until the vehicle's current remaining mileage is reduced to the preset mileage, and the electric drive waste heat is switched to heating the vehicle's passenger compartment. Therefore, based on the estimated time when the vehicle ends this trip, it is possible to more accurately predict whether the vehicle will make the next trip on the same day, so as to adjust the heating mileage of the power battery and passenger compartment by the electric drive waste heat according to the prediction results, further reduce the energy waste caused by continuous heat dissipation of the battery after parking, and improve the energy utilization efficiency of the electric drive waste heat.

[0068] To further improve the energy utilization efficiency of electric drive waste heat, in some embodiments, it is determined that the current remaining mileage is greater than a preset mileage, and the power battery of the vehicle is heated by the electric drive waste heat, including:

[0069] When the target mileage of the vehicle reaches a mileage threshold, determining that the current remaining mileage is greater than a preset mileage, and heating the power battery of the vehicle by using electric drive waste heat;

[0070] The target mileage is determined according to the starting position and destination of the vehicle, and the mileage threshold is greater than the preset mileage.

[0071] In some embodiments, before the vehicle is heated by the waste heat of the electric drive, the target mileage of the vehicle for this trip may be determined based on the starting position and destination of the vehicle. For example, the target mileage of the vehicle for this trip may be determined based on the starting position and destination of the vehicle input in the electronic navigation.

[0072] After obtaining the target mileage of the vehicle for this trip, it can be detected whether the target mileage of the vehicle reaches a mileage threshold greater than the preset mileage. If the target mileage is less than the mileage threshold, it means that this trip is a short-distance trip and there is no need to increase the discharge of the power battery. At this time, there is no need to heat the power battery by the electric drive waste heat. At this time, the passenger compartment of the vehicle can be heated by the electric drive waste heat. If there is a heating demand in the passenger compartment, the passenger compartment of the vehicle can be heated by the electric drive waste heat. If the target mileage reaches the mileage threshold, it means that this trip is a long-distance trip and the discharge of the power battery needs to be increased. At this time, when the current remaining mileage is greater than the preset mileage, the power battery of the vehicle is heated by the electric drive waste heat, thereby improving the energy utilization efficiency of the electric drive waste heat.

[0073] To further reduce energy waste, in some embodiments, the mileage threshold may be determined based on the start time of the vehicle's travel.

[0074] Exemplarily, it is possible to detect whether the start time of the vehicle's travel is earlier than the preset time to determine whether the user will use the vehicle for the next travel on the same day. If the start time is earlier than the preset time, it means that the user will use the vehicle for the next travel on the same day. Even if the power battery temperature is high after the parking and resting, it can be beneficial to the user's next travel, and the degree of energy waste is relatively small. At this time, the mileage threshold can be determined to be the first threshold with a smaller mileage; if the start time is later than the preset time, it means that this travel is the last travel of the vehicle on the same day. If the power battery temperature is high after the parking and resting, the heat is only used for heat dissipation, resulting in complete energy waste. At this time, the mileage threshold can be determined to be the second threshold greater than the first threshold, so that the residual heat of the electric drive is used to heat the battery only when the mileage of the vehicle is long enough, thereby reducing energy waste.

[0075] Alternatively, the mileage threshold may be determined based on an estimated time when the vehicle arrives at the destination.

[0076] For example, it is possible to detect whether the estimated time when the vehicle arrives at the destination is earlier than the preset time to determine whether the user will use the vehicle for the next trip on the same day. If the estimated time is earlier than the preset time, it means that the user will use the vehicle for the next trip on the same day. Even if the power battery temperature is high after the parking and resting, it can be beneficial to the user's next trip, and the degree of energy waste is relatively small. At this time, the mileage threshold can be determined to be the first threshold with a smaller mileage; if the estimated time is later than the preset time, it means that this trip is the last trip of the vehicle on the same day. If the power battery temperature is high after the parking and resting, the heat is only used for heat dissipation, resulting in complete energy waste. At this time, the mileage threshold can be determined to be the second threshold greater than the first threshold, so that the residual heat of the electric drive is used to heat the battery only when the mileage of the vehicle is long enough, thereby reducing energy waste.

Before the vehicle stops and is stationary, the residual heat of the electric drive is stopped from being used to heat the power battery in advance, and the residual heat of the electric drive is used to heat the passenger compartment instead, thereby reducing the battery temperature after the vehicle stops and is stationary, reducing the energy waste caused by the continuous heat dissipation of the battery after the vehicle stops and is stationary, and at the same time, the residual heat of the electric drive can be further utilized, thereby improving the energy utilization efficiency of the residual heat of the electric drive.
