Description

Technical Field

[0001] The present application relates to the field of vehicles, and particularly to a thermal management control method for a vehicle, a thermal management control device for a vehicle, a computer-readable storage medium, a vehicle thermal management system, and a vehicle. Background Art

[0002] When the outdoor ambient temperature is relatively low, the cruising range of electric vehicles will have a large attenuation. A reasonable battery thermal management strategy, such as heating the battery when the battery power is low, can increase the cruising range to a certain extent. However, when the user has reached the destination or there is no timely charging requirement, the heat of the heated battery pack is wasted into the surrounding low-temperature air during parking, resulting in power waste. Summary of the Invention

[0003] In view of the above problems, the present application provides a vehicle and its thermal management control method, device, thermal management system, and storage medium, which obtain the cruising ranges corresponding to multiple thermal management strategies, determine the cruising range information of the target thermal management strategy according to the cruising ranges corresponding to the multiple thermal management strategies, then control the display device to display the cruising range information, and when receiving a control instruction, control the vehicle thermal management strategy according to the control instruction. Thus, the cruising range information is displayed through the display device for human-computer interaction, improving the user experience, and controlling the thermal management strategy according to the control instruction, reducing the energy waste caused by misheating, and improving the overall efficiency of the vehicle.

[0004] In a first aspect, the present application provides a thermal management control method for a vehicle, which obtains the cruising ranges corresponding to multiple thermal management strategies; determines the cruising range information of the target thermal management strategy according to the cruising ranges corresponding to the multiple thermal management strategies; controls the display device to display the cruising range information; and responds to a control instruction and controls the vehicle thermal management strategy according to the control instruction, where the control instruction is an instruction issued based on the cruising range information of the target thermal management strategy.

[0005] In the technical solution of the embodiment of the present application, the cruising range corresponding to multiple thermal management strategies is first obtained, and then the cruising range information of the target thermal management strategy is determined according to the cruising range corresponding to the multiple thermal management strategies, and the cruising range information is displayed by controlling the display device (such as the vehicle-mounted display screen) for the user to select. The user decides whether to select the target thermal management strategy based on actual needs and in combination with the cruising range information, and issues a control instruction. After receiving the control instruction, respond to the control instruction, and control the vehicle thermal management strategy according to the control instruction. For example, when the user selects the target thermal management strategy, the vehicle is controlled to switch to the target thermal management strategy; for another example, when the user does not select the target thermal management strategy, the vehicle is controlled to keep the current thermal management strategy unchanged. Thus, the cruising range information is displayed on the display device to perform human-computer interaction, improve user experience, and control the thermal management strategy according to the control instruction to reduce energy waste caused by misheating and improve the overall efficiency of the vehicle.

[0006] In some embodiments, the cruising range information includes an emergency cruising range, and the vehicle thermal management strategy is controlled according to the control instruction, including: when the control instruction is to select the emergency cruising range, switching to the thermal management strategy corresponding to the emergency cruising range; when the control instruction is not to select the emergency cruising range, keeping the current thermal management strategy unchanged.

[0007] The emergency cruising range is displayed on a display device to interact with the user for selection. When the user selects the emergency cruising range, it means that the user needs the battery to maintain a longer cruising range. At this time, the thermal management strategy corresponding to the emergency cruising range is switched to increase the vehicle's cruising range. When the user does not select the emergency cruising range, it means that the user does not need the battery to maintain a longer cruising range. The current thermal management strategy remains unchanged to reduce energy waste and improve the vehicle's overall efficiency.

[0008] In some embodiments, determining the cruising range information of a target thermal management strategy based on the cruising ranges corresponding to multiple thermal management strategies includes: determining the target thermal management strategy based on the cruising ranges corresponding to multiple thermal management strategies; determining the cruising range information based on the target thermal management strategy and its corresponding cruising range.

[0009] The target thermal management strategy is determined according to the cruising ranges corresponding to multiple thermal management strategies. For example, the thermal management strategy with the longest cruising range is used as the target thermal management strategy, or several thermal management strategies with large cruising ranges are used as the target thermal management strategy. Then the target thermal management strategy and its corresponding cruising range are used as cruising range information, that is, the cruising range information includes the thermal management strategy and its corresponding cruising range. The cruising range information of the vehicle is displayed on a display device so that users can choose according to their own needs to reduce vehicle energy waste.

[0010] In some embodiments, determining a target thermal management strategy according to the cruising ranges corresponding to multiple thermal management strategies includes: determining a preset number of thermal management strategies as the target thermal management strategy in the order of the magnitudes of the cruising ranges corresponding to the multiple thermal management strategies.

[0011] The thermal management strategy with the longest cruising range can be used as the target thermal management strategy, or multiple thermal management strategies can be used as the target thermal management strategy, providing users with multiple selection methods, improving the user experience, and also maximizing the vehicle's energy utilization rate as much as possible.

[0012] In some embodiments, the above thermal management control method for a vehicle further includes: determining the time interval for displaying the emergency cruising range according to the emergency cruising range. When the emergency cruising range is larger, the time interval for displaying the emergency cruising range is shorter, that is, the user is reminded more frequently to prevent the user from missing it.

[0013] In some embodiments, determining the time interval for displaying the emergency cruising range according to the emergency cruising range includes: in the case where the emergency cruising range is greater than the preset cruising range, determining the time interval according to the emergency cruising range, where the larger the emergency cruising range, the smaller the time interval, and the smaller the emergency cruising range, the larger the time interval; in the case where the emergency cruising range is less than the preset cruising range threshold, controlling the display device to stop displaying the emergency cruising range.

[0014] As the battery power decreases, the emergency cruising range will also gradually decrease. When the emergency cruising range is relatively large, increase the frequency of interaction with the user so that the user can select a suitable thermal management strategy in advance according to their own needs, thereby obtaining a greater increase in the emergency cruising range; when the emergency cruising range is relatively small, the increase in the emergency cruising range is limited. At this time, the display device can be controlled to stop displaying the emergency cruising range and no longer interact with the user.

[0015] In some embodiments, before controlling the display device to display the cruising range information, the method further includes: determining that the battery power of the vehicle is less than the preset power threshold. Only when the battery power of the vehicle is small, control the display device to display the cruising range information, reducing the interference of the displayed cruising range information to the user and improving the user experience.

[0016] In some embodiments, the multiple thermal management strategies include: using the waste heat of the electric drive to heat the battery, using a PTC (Positive Temperature Coefficient) to heat the battery, and using a heat pump to heat the battery.

[0017] In some embodiments, the cruising range corresponding to multiple thermal management strategies is obtained, including: obtaining the outdoor ambient temperature and the battery temperature; determining the vehicle operating parameters within a preset time before the current moment based on the outdoor ambient temperature and the battery temperature; and determining the cruising range corresponding to each thermal management strategy based on the battery power and the vehicle operating parameters.

[0018] In a second aspect, the present application provides a thermal management control device for a vehicle, comprising: an acquisition module for acquiring the cruising range corresponding to multiple thermal management strategies; a determination module for determining the cruising range information of a target thermal management strategy based on the cruising range corresponding to multiple thermal management strategies; a control module for controlling a display device to display the cruising range information, and responding to control instructions, and controlling the vehicle thermal management strategy according to the control instructions, wherein the control instructions are instructions issued based on the cruising range information of the target thermal management strategy.

[0019] In the technical solution of the embodiment of the present application, the cruising range corresponding to multiple thermal management strategies is obtained by the acquisition module, and then the cruising range information of the target thermal management strategy is determined by the determination module according to the cruising range corresponding to the multiple thermal management strategies, and the control module controls the display device (such as the vehicle display screen) to display the cruising range information for the user to select. The user decides whether to select the target thermal management strategy according to actual needs and in combination with the cruising range information, and issues a control instruction. After receiving the control instruction, the control module responds to the control instruction and controls the vehicle thermal management strategy according to the control instruction. For example, when the user selects the target thermal management strategy, the control module controls the vehicle to switch to the target thermal management strategy; for another example, when the user does not select the target thermal management strategy, the control module controls the vehicle to keep the current thermal management strategy unchanged. Thus, the cruising range information is displayed on the display device to perform human-computer interaction, improve user experience, and control the thermal management strategy according to the control instruction, reduce energy waste caused by misheating, and improve the overall efficiency of the vehicle.

[0020] In some embodiments, the cruising range information includes an emergency cruising range, and the control module controls the vehicle thermal management strategy according to the control instruction, specifically for: when the control instruction is to select the emergency cruising range, switching to the thermal management strategy corresponding to the emergency cruising range; when the control instruction is not to select the emergency cruising range, keeping the current thermal management strategy unchanged.

[0021] The control module controls the display device to display the emergency endurance mileage, interacts with the user for the user to make a selection. When the user selects the emergency endurance mileage, it indicates that the user needs the battery to maintain a longer endurance mileage. At this time, the control module switches the current thermal management strategy to the thermal management strategy corresponding to the emergency endurance mileage to increase the vehicle's endurance mileage; when the user does not select the emergency endurance mileage, it means that the user does not need the battery to maintain a longer endurance mileage, and the control module keeps the current thermal management strategy unchanged to reduce energy waste and improve the vehicle's overall efficiency.

[0022] In some embodiments, the determination module determines the endurance mileage information of the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies. Specifically, it is used to: determine the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies; determine the endurance mileage information according to the target thermal management strategy and its corresponding endurance mileage.

[0023] The determination module determines the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies. For example, it takes the thermal management strategy with the maximum endurance mileage as the target thermal management strategy, or it can also take several thermal management strategies with relatively large endurance mileage as the target thermal management strategies. Then the determination module takes the target thermal management strategy and its corresponding endurance mileage as the endurance mileage information, that is, the endurance mileage information includes the thermal management strategy and its corresponding endurance mileage. The endurance mileage information of the vehicle is displayed through the display device so that the user can make a selection according to their own needs and reduce the vehicle's energy waste.

[0024] In some embodiments, the determination module determines the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies. Specifically, it is used to: determine a preset number of thermal management strategies as the target thermal management strategy according to the order of the endurance mileage corresponding to multiple thermal management strategies from large to small.

[0025] The thermal management strategy with the most endurance mileage can be taken as the target thermal management strategy, or multiple thermal management strategies can be taken as the target thermal management strategies, providing the user with multiple selection methods, improving the user experience, and at the same time maximizing the vehicle's energy utilization rate.

[0026] In some embodiments, the control module is further used to: determine the time interval for displaying the emergency endurance mileage according to the emergency endurance mileage. When the emergency endurance mileage is larger, the time interval for displaying the emergency endurance mileage is shorter, that is, the reminder to the user is more frequent to prevent the user from missing it.

[0027] In some embodiments, the control module determines the time interval for displaying the emergency endurance mileage according to the emergency endurance mileage, specifically: when the emergency endurance mileage is greater than the preset endurance mileage, the time interval is determined according to the emergency endurance mileage, wherein the greater the emergency endurance mileage, the smaller the time interval, and the smaller the emergency endurance mileage, the larger the time interval; when the emergency endurance mileage is less than the preset endurance mileage threshold, the display device is controlled to stop displaying the emergency endurance mileage.

[0028] As the battery power decreases, the emergency endurance mileage will also gradually decrease. When the emergency endurance mileage is relatively large, increasing the frequency of interaction with the user allows the user to select a suitable thermal management strategy in advance according to their own needs, thereby obtaining a relatively large increase in the emergency endurance mileage; when the emergency endurance mileage is relatively small, the increase in the emergency endurance mileage is limited. At this time, the display device can be stopped from displaying the emergency endurance mileage and no longer interact with the user.

[0029] In a third aspect, the present application provides a computer-readable storage medium, on which a thermal management control program for a vehicle is stored. When the thermal management control program for the vehicle is executed by a processor, the above-mentioned thermal management control method for the vehicle is implemented.

[0030] In a fourth aspect, the present application provides a vehicle thermal management system, including a memory, a processor, and a thermal management control program for the vehicle stored on the memory and executable on the processor. When the processor executes the thermal management control program for the vehicle, the above-mentioned thermal management control method for the vehicle is implemented.

[0031] In a fifth aspect, the present application provides a vehicle, including a memory, a processor, and a thermal management control program for the vehicle stored on the memory and executable on the processor. When the processor executes the thermal management control program for the vehicle, the above-mentioned thermal management control method for the vehicle is implemented.

[0046] When the outdoor ambient temperature is relatively low, the driving range of electric vehicles will have a large attenuation. A reasonable battery thermal management strategy, such as heating the battery when the battery power is low, can increase the driving range to a certain extent. However, when the user has reached the destination or there is no timely charging requirement, the heat of the heated battery pack is dissipated into the surrounding low-temperature air during the parking process, resulting in a waste of electricity.

[0047] If the user's current expected driving range can be accurately known, the thermal management strategy in a low-temperature environment can be effectively controlled. However, usually, the driving range required by the user needs to be obtained through navigation information, which requires the vehicle-mounted computer to be connected or the mobile terminal to be connected to the vehicle controller. That is, when the user uses navigation, the versatility is not high and it is not applicable to working conditions without navigation.

[0048] Therefore, the present application displays the driving range information through a display device for the user to select. According to the user's control instruction, it is determined whether to turn on the battery heating, and then a suitable thermal management strategy is matched to improve the driving range of the vehicle, avoid energy waste, and make every degree of electricity play its own value. Moreover, through the man-machine interaction method, the user's driving experience can be improved.

[0049] For the convenience of description, the following embodiments are combined with Figure 1 to illustrate the thermal management control method of the vehicle of the present application.

[0050] Refer to Figure 1, the thermal management control method of the vehicle in this application may include the following steps:

[0051] S11, obtain the cruising ranges corresponding to multiple thermal management strategies.

[0052] S12, determine the cruising range information of the target thermal management strategy according to the cruising ranges corresponding to multiple thermal management strategies.

[0053] S13, control the display device to display the cruising range information.

[0054] S14, in response to a control instruction, and control the vehicle thermal management strategy according to the control instruction, where the control instruction is an instruction issued based on the cruising range information of the target thermal management strategy.

[0055] Specifically, first obtain the cruising ranges corresponding to multiple thermal management strategies, then determine the cruising range information of the target thermal management strategy according to the cruising ranges corresponding to multiple thermal management strategies, and display the cruising range information through a control display device (such as an in-vehicle display screen) for the user to select. The user decides whether to select the target thermal management strategy based on actual needs and in combination with the cruising range information, and issues a control instruction. For example, the user touches a corresponding position on the display device, such as "confirm" or "cancel", or can also control the display device through a mechanical button to issue a control instruction. After receiving the control instruction, respond to the control instruction and control the vehicle thermal management strategy according to the control instruction. For example, when the user selects the cruising range information by touching a corresponding position on the display device, determine the corresponding thermal management strategy according to the selected cruising range information by the user and switch to this thermal management strategy; another example is that when the user does not select the cruising range information by touching a corresponding position on the display device, or the user does not issue a control instruction within a certain period of time, keep the current thermal management strategy unchanged. Thus, by displaying the cruising range information through the display device, human-machine interaction is carried out to improve the user experience, bring a sense of technology experience to the user, and to a certain extent, can also relieve the user's anxious mood, and control the thermal management strategy according to the control instruction, reducing the energy waste caused by misheating and improving the overall efficiency of the vehicle.

[0056] In addition, in the case where the vehicle has no navigation information, by interacting with the user, a suitable thermal management strategy is matched to improve the overall efficiency of the vehicle. In the case where the vehicle has navigation information, the vehicle controller can directly determine a suitable thermal management strategy, or the cruising range information can be displayed through the display device for the user to actively select, improving the vehicle-human interaction effect.

[0057] It should be noted that the target thermal management strategy may include one thermal management strategy or multiple thermal management strategies. Among them, when the target thermal management strategy includes one thermal management strategy, the endurance mileage information includes the endurance mileage information of this thermal management strategy; when the target thermal management strategy includes multiple thermal management strategies, the endurance mileage information includes the endurance mileage information corresponding to multiple thermal management strategies, and the endurance mileage information corresponding to multiple thermal management strategies will be displayed on the display device.

[0058] In some embodiments, the endurance mileage information includes the emergency endurance mileage. Controlling the vehicle thermal management strategy according to the control instruction includes: when the control instruction is to select the emergency endurance mileage, switching to the thermal management strategy corresponding to the emergency endurance mileage; when the control instruction is not to select the emergency endurance mileage, keeping the current thermal management strategy unchanged.

[0059] Specifically, the emergency endurance mileage generally refers to the endurance mileage that the battery can increase by adopting a certain method when the battery power is lower than a certain value. For example, the emergency endurance mileage is the endurance mileage of the target thermal management strategy minus the endurance mileage of the current thermal management strategy. For example, when the vehicle is driving in a low-temperature environment, if the battery power is 20% and the available endurance mileage is 10 km, at this time, by heating the battery, the endurance mileage can reach 15 km, then the emergency endurance mileage is 5 km (15 km - 10 km).

[0060] During the vehicle driving process, the emergency endurance mileage is displayed on the display device in real time to interact with the user for the user to select. When the user selects the emergency endurance mileage, it means that the user needs the battery to maintain a longer endurance mileage to complete the remaining journey. At this time, switch to the thermal management strategy corresponding to the emergency endurance mileage to increase the vehicle's endurance mileage; when the user does not select the emergency endurance mileage, it means that the user does not need the battery to maintain a longer endurance mileage. For example, when the user is about to stop, keep the current thermal management strategy unchanged to reduce energy waste and improve the vehicle's comprehensive efficiency.

[0061] In some embodiments, determining the endurance mileage information of the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies includes: determining the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies; determining the endurance mileage information according to the target thermal management strategy and its corresponding endurance mileage.

[0062] In some embodiments, determining the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies includes: determining a preset number of thermal management strategies as the target thermal management strategy in the order of the magnitudes of the endurance mileage corresponding to multiple thermal management strategies. Among them, the preset number can be calibrated according to the actual situation. For example, the preset number can be 1, or 2, or 3, and does not exceed the number of thermal management strategies.

[0063] Specifically, a target thermal management strategy is determined according to the driving ranges corresponding to multiple thermal management strategies. For example, the thermal management strategy with the maximum driving range is used as the target thermal management strategy, or the first few thermal management strategies with relatively large driving ranges can be used as the target thermal management strategies. Then, the target thermal management strategy and its corresponding driving range are used as the driving range information, that is, the driving range information includes the thermal management strategy and its corresponding driving range. Among them, when there are multiple target thermal management strategies, the driving range information includes each thermal management strategy and its corresponding driving range. The driving range information of the vehicle is displayed through a display device, providing multiple selection methods for the user, so that the user can make a choice according to their own needs, improving the user experience, alleviating the user's anxiety to a certain extent, bringing a sense of technology to the user, and at the same time reducing the energy waste of the vehicle. In some embodiments, the above thermal management control method for the vehicle further includes: determining the time interval for displaying the emergency driving range according to the emergency driving range.

[0064] In some embodiments, determining the time interval for displaying the emergency driving range according to the emergency driving range includes: in the case where the emergency driving range is greater than the preset driving range, determining the time interval according to the emergency driving range, where the greater the emergency driving range, the smaller the time interval, and the smaller the emergency driving range, the larger the time interval; in the case where the emergency driving range is less than the preset driving range threshold, controlling the display device to stop displaying the emergency driving range. Among them, the preset driving range threshold can be calibrated according to the actual situation.

[0065] Specifically, as the battery power decreases, the emergency driving range will gradually decrease. This is mainly because heating the battery also requires wasting battery power. Therefore, the lower the battery power, the smaller the emergency driving range; the higher the battery power, the larger the emergency driving range. When the emergency driving range is relatively large, the time interval for displaying the emergency driving range is shorter, increasing the frequency of interaction with the user, that is, reminding the user more frequently, preventing the user from missing it, and allowing the user to select a suitable thermal management strategy in advance according to their own needs, so as to obtain a greater improvement in the emergency driving range. When the emergency driving range is relatively small, the improvement in the emergency driving range is limited. At this time, the display device can be controlled to stop displaying the emergency driving range and no longer interact with the user. For example, when the remaining battery power is 30%, the emergency driving range is 10 km, and the emergency driving range is displayed once every 30 s; when the remaining battery power is 20%, the emergency driving range is 6 km, and the emergency driving range is displayed once every 45 s; when the remaining battery power is 10%, the emergency driving range is 1 km or heating the battery will use up the remaining power, and at this time, there is no need to display the emergency driving range.

[0066] In some embodiments, before controlling the display device to display the driving range information, the method further includes: determining that the battery power of the vehicle is less than the preset power threshold.

[0067] That is to say, when the battery has a relatively large amount of power, there is no need to display the emergency cruising range, so as to avoid disturbing the user by frequently displaying the cruising range. For example, when a user on the co-pilot seat is using the display device to watch a video, the frequent display of the emergency cruising range will affect the user's video viewing. Therefore, when the battery power of the vehicle is relatively small, the display device is controlled to display the cruising range information, which can not only reduce the interference of the displayed cruising range information to the user, but also bring a sense of technology experience to the user. The user can know the size of the emergency cruising range in real time, and to a certain extent, relieve the anxiety of the driver caused by the possible inability to reach the destination due to insufficient battery power, thus improving the user experience.

[0068] In some embodiments, the multiple thermal management strategies include: using the waste heat of the electric drive to heat the battery, using a PTC to heat the battery, and using a heat pump to heat the battery.

[0069] In some embodiments, obtaining the cruising range corresponding to the multiple thermal management strategies includes: obtaining the outdoor ambient temperature and the battery temperature; determining the vehicle operation parameters within a preset time before the current moment according to the outdoor ambient temperature and the battery temperature; and determining the cruising range corresponding to each thermal management strategy according to the battery power and the vehicle operation parameters. The preset time can be further calibrated according to the actual situation.

[0070] Specifically, the vehicle operation parameters may include the average discharge power, the average discharge current, and the power consumption per 100 kilometers. Exemplarily, the vehicle operation parameters may include the average discharge power. During the vehicle driving process, the outdoor ambient temperature, the battery power W (kmh), and the cell temperature are obtained, and the average discharge power P (kw) within a past period of time is determined. According to the battery power and the average discharge power, the dischargeable time t (h) can be determined. By multiplying the dischargeable time by the average vehicle speed V (km / h) within the past period of time, the cruising range S (km) under each thermal management strategy can be determined. For example, S=(W / P)*V. The average discharge power under different thermal management strategies can be obtained by looking up a table according to the outdoor ambient temperature and the cell temperature, that is, the average discharge power under different thermal management strategies can be determined, and then the cruising range under different thermal management strategies can be determined.

[0071] Exemplarily, the vehicle operating parameters may include the average discharge current. During vehicle driving, the remaining battery capacity Q (Ah) can be determined according to the battery charge, and the average discharge current I (A) over a past period can be determined according to the outdoor ambient temperature, the remaining battery capacity, and the cell temperature. The dischargeable time t (h) can be determined according to the remaining battery capacity and the average discharge current. The cruising range S (km) under each thermal management strategy can be determined by multiplying the dischargeable time by the average vehicle speed V (km / h) over the past period. For example, S = (Q / P) * V. The average discharge current under different thermal management strategies can be obtained by looking up a table according to the outdoor ambient temperature and the cell temperature, that is, the average discharge current under different thermal management strategies can be determined, and then the cruising range under different thermal management strategies can be determined.

[0072] Exemplarily, the vehicle operating parameters may include the power consumption per 100 kilometers. During vehicle driving, the cruising range S (km) can be obtained according to the power consumption per 100 kilometers E (kwh / 100km) of the vehicle under the standard cruising condition and the battery charge W (kmh). For example, S = (W / E) * 100. The power consumption per 100 kilometers under different thermal management strategies can be obtained by looking up a table according to the outdoor ambient temperature and the cell temperature, that is, the power consumption per 100 kilometers under different thermal management strategies can be determined, and then the cruising range under different thermal management strategies can be determined. Among them, the standard cruising condition can be NEDC (New European Driving Cycle), or CLTC (China Automotive Test Cycle).

[0073] It should be noted that the method for obtaining the cruising ranges corresponding to multiple thermal management strategies is not limited to the method in the above embodiments, and other methods are also possible, which are not limited here.

[0074] As a specific example, obtain relevant information such as outdoor ambient temperature, battery power and battery temperature. Combined with the specific types of heating modes that can be achieved by the vehicle thermal management system architecture, calculate the cruising range corresponding to different thermal management strategies in real time. For example, the cruising range corresponding to the current thermal management strategy, the cruising range corresponding to using the residual heat of the electric drive to heat the battery, the cruising range corresponding to using PTC to actively heat the battery, and the cruising range corresponding to using a heat pump to actively heat the battery. Among these thermal management strategies, the thermal management strategy with the longest cruising range is the target thermal management strategy, or select 2-3 thermal management strategies with longer cruising range as the target thermal management strategy. When the cruising range information includes emergency cruising range, calculate the emergency cruising range, for example, the cruising range corresponding to the target thermal management strategy - the cruising range of the current strategy = emergency cruising range. When the battery power drops to a certain level, start to interact with the user. The interaction can be displayed on a display screen, or other display or communication devices (such as mobile phones). When the cruising range information includes emergency cruising range, the displayed content is the emergency cruising range. When the cruising range information includes the thermal management strategy and the corresponding cruising range, the thermal management strategy and the corresponding cruising range are displayed. The display frequency may be related to the size of the emergency cruising range. For example, when the emergency cruising range is larger, the interaction frequency is higher. When the emergency cruising range is lower than a certain value, the display stops, that is, the interaction with the user stops. After displaying the cruising range information, the user's feedback information is received, that is, whether the user selects the emergency cruising range or selects a certain thermal management strategy. After receiving the user feedback information, the actuator action in the thermal management system is controlled to switch to the target thermal management strategy, increase the current cruising range, and update the cruising range information. If no feedback information is received from the user or the user selects no, that is, the emergency cruising range is not used, the current thermal management strategy remains unchanged.

[0075] In summary, in the technical solution of the embodiment of the present application, the cruising range corresponding to multiple thermal management strategies is first obtained, and then the cruising range information of the target thermal management strategy is determined according to the cruising range corresponding to the multiple thermal management strategies, and the cruising range information is displayed by controlling the display device (such as a vehicle-mounted display screen) for user selection. The user decides whether to select the target thermal management strategy based on actual needs and in combination with the cruising range information, and issues a control instruction. After receiving the control instruction, respond to the control instruction, and control the vehicle thermal management strategy according to the control instruction. For example, when the user selects the target thermal management strategy, the vehicle is controlled to switch to the target thermal management strategy; for another example, when the user does not select the target thermal management strategy, the vehicle is controlled to keep the current thermal management strategy unchanged. Thus, the cruising range information is displayed on the display device to perform human-computer interaction, improve user experience, and control the thermal management strategy according to the control instruction to reduce energy waste caused by misheating and improve the overall efficiency of the vehicle.

[0076] Corresponding to the above embodiments, the present application also proposes a thermal management control device for a vehicle.

[0077] As Figure 2 shown, the thermal management control device 100 for a vehicle according to the present application may include: an acquisition module 110 for acquiring the cruising ranges corresponding to multiple thermal management strategies; a determination module 120 for determining the cruising range information of the target thermal management strategy according to the cruising ranges corresponding to the multiple thermal management strategies; and a control module 130 for controlling a display device to display the cruising range information, and in response to a control instruction, and controlling the vehicle thermal management strategy according to the control instruction, wherein the control instruction is an instruction issued based on the cruising range information of the target thermal management strategy.

[0078] Specifically, the acquisition module 110 acquires the cruising ranges corresponding to multiple thermal management strategies, then the determination module 120 determines the cruising range information of the target thermal management strategy according to the cruising ranges corresponding to the multiple thermal management strategies, and the control module 130 controls a display device (such as an in-vehicle display screen) to display the cruising range information for the user to select. The user decides whether to select the target thermal management strategy based on the actual needs and in combination with the cruising range information, and issues a control instruction. For example, the user can touch a corresponding position on the display device, such as confirm, cancel, etc., or can also issue a control instruction by mechanically pressing a key to control the display device. After receiving the control instruction, the control module 130 responds to the control instruction and controls the vehicle thermal management strategy according to the control instruction. For example, when the user selects the cruising range information by touching a corresponding position on the display device, the corresponding thermal management strategy is determined according to the selected cruising range information by the user, and the vehicle switches to this thermal management strategy; another example is that when the user does not select the cruising range information by touching a corresponding position on the display device, or the user does not issue a control instruction within a certain period of time, the current thermal management strategy remains unchanged. Thus, by displaying the cruising range information on the display device for human-machine interaction, the user experience is improved, a technological experience is brought to the user, and to a certain extent, the user's anxiety can also be alleviated, and the thermal management strategy is controlled according to the control instruction, reducing the energy waste caused by misheating and improving the overall efficiency of the vehicle.

[0079] In addition, in the case where the vehicle has no navigation information, a suitable thermal management strategy is matched by interacting with the user to improve the overall efficiency of the vehicle. In the case where the vehicle has navigation information, the vehicle controller can directly determine a suitable thermal management strategy, or the cruising range information can be displayed on the display device for the user to actively select, improving the vehicle-human interaction effect.

[0080] In some embodiments, the endurance mileage information includes the emergency endurance mileage. The control module 130 controls the vehicle thermal management strategy according to the control instruction, specifically for: when the control instruction is to select the emergency endurance mileage, switching to the thermal management strategy corresponding to the emergency endurance mileage; when the control instruction is not to select the emergency endurance mileage, keeping the current thermal management strategy unchanged.

[0081] Specifically, the emergency endurance mileage generally refers to the additional endurance mileage that the battery can provide when the battery power is lower than a certain value. For example, the emergency endurance mileage is the endurance mileage of the target thermal management strategy minus the endurance mileage of the current thermal management strategy. For example, when the vehicle is driving in a low-temperature environment, if the battery power is 20% and the available endurance mileage is 10 km, at this time, by heating the battery, the endurance mileage can reach 15 km, then the emergency endurance mileage is 5 km (15 km - 10 km). During the vehicle driving process, the control module 130 controls the display device to display the emergency endurance mileage and interacts with the user for the user to select. When the user selects the emergency endurance mileage, it means that the user needs the battery to maintain a longer endurance mileage. At this time, the control module 130 switches the current thermal management strategy to the thermal management strategy corresponding to the emergency endurance mileage to increase the vehicle's endurance mileage; when the user does not select the emergency endurance mileage, it means that the user does not need the battery to maintain a longer endurance mileage, and the control module 130 keeps the current thermal management strategy unchanged to reduce energy waste and improve the vehicle's overall efficiency.

[0082] In some embodiments, the determination module 120 determines the endurance mileage information of the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies, specifically for: determining the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies; determining the endurance mileage information according to the target thermal management strategy and its corresponding endurance mileage.

[0083] In some embodiments, the determination module 120 determines the target thermal management strategy according to the endurance mileage corresponding to multiple thermal management strategies, specifically for: determining a preset number of thermal management strategies as the target thermal management strategy in the order of the magnitudes of the endurance mileage corresponding to multiple thermal management strategies. Among them, the preset number can be calibrated according to the actual situation. For example, the preset number can be 1, or 2, or 3, and does not exceed the number of thermal management strategies.

[0084] Specifically, the determination module 120 determines the target thermal management strategy according to the cruising ranges corresponding to multiple thermal management strategies. For example, the thermal management strategy with the maximum cruising range is used as the target thermal management strategy, or several thermal management strategies with relatively large cruising ranges can be used as the target thermal management strategies. Then, the determination module 120 uses the target thermal management strategy and its corresponding cruising range as the cruising range information, that is, the cruising range information includes the thermal management strategy and its corresponding cruising range. Wherein, when there are multiple target thermal management strategies, the cruising range information includes each thermal management strategy and its corresponding cruising range. By displaying the cruising range information of the vehicle through a display device, multiple selection methods are provided to the user, so that the user can make a choice according to their own needs, improving the user experience, alleviating the user's anxiety to a certain extent, bringing a sense of technology to the user, and at the same time reducing the energy waste of the vehicle.

[0085] In some embodiments, the control module is further configured to: determine the time interval for displaying the emergency cruising range according to the emergency cruising range.

[0086] In some embodiments, the control module determines the time interval for displaying the emergency cruising range according to the emergency cruising range, specifically: in the case where the emergency cruising range is greater than the preset cruising range, determine the time interval according to the emergency cruising range, wherein the greater the emergency cruising range, the smaller the time interval, and the smaller the emergency cruising range, the larger the time interval; in the case where the emergency cruising range is less than the preset cruising range threshold, control the display device to stop displaying the emergency cruising range. The preset cruising range threshold can be calibrated according to the actual situation.

[0087] Specifically, as the battery power decreases, the emergency cruising range will also gradually decrease. This is mainly because heating the battery also consumes battery power. Therefore, the lower the battery power, the smaller the emergency cruising range; the higher the battery power, the larger the emergency cruising range. When the emergency cruising range is relatively large, the time interval for displaying the emergency cruising range is shorter, increasing the frequency of interaction with the user, that is, reminding the user more frequently, preventing the user from missing it, and allowing the user to select a suitable thermal management strategy in advance according to their own needs, so as to obtain a greater improvement in the emergency cruising range; when the emergency cruising range is relatively small, the improvement of the emergency cruising range is limited. At this time, the display device can be controlled to stop displaying the emergency cruising range and no longer interact with the user. For example, when the remaining battery power is 30%, the emergency cruising range is 10 km, and the emergency cruising range is displayed every 30 s; when the remaining battery power is 20%, the emergency cruising range is 6 km, and the emergency cruising range is displayed every 45 s; when the remaining battery power is 10%, the emergency cruising range is 1 km or heating the battery will use up the remaining power, and at this time, there is no need to display the emergency cruising range.

[0088] In some embodiments, the control module 130 is further configured to determine that the battery power of the vehicle is less than a preset power threshold before controlling the display device to display the remaining mileage information.

[0089] That is to say, when the battery power is relatively high, there is no need to display the emergency remaining mileage, so as to avoid disturbing the user by frequently displaying the remaining mileage. For example, when a user on the co-pilot seat is using the display device to watch a video, the frequent display of the emergency remaining mileage will affect the user's mood of watching the video. Therefore, when the battery power of the vehicle is relatively low, the display device is controlled to display the remaining mileage information, which can not only reduce the interference of the displayed remaining mileage information to the user, but also bring a sense of technology experience to the user. The user can know the size of the emergency remaining mileage in real time, and to a certain extent, relieve the anxiety of the driver caused by the possible inability to reach the destination due to insufficient battery power, thereby improving the user experience.

[0090] In some embodiments, the multiple thermal management strategies include: heating the battery with the waste heat of the electric drive, heating the battery with PTC, and heating the battery with a heat pump.

[0091] In some embodiments, the obtaining module 110 obtains the remaining mileage corresponding to the multiple thermal management strategies, and specifically is configured to: obtain the outdoor ambient temperature and the battery temperature; determine the vehicle operation parameters within a preset time before the current moment according to the outdoor ambient temperature and the battery temperature; and determine the remaining mileage corresponding to each thermal management strategy according to the battery power and the vehicle operation parameters. The preset time can be further calibrated according to the actual situation.

[0092] Specifically, the vehicle operation parameters may include the average discharge power, the average discharge current, and the power consumption per 100 kilometers. Exemplarily, the vehicle operation parameters may include the average discharge power. During the vehicle driving process, the obtaining module 110 obtains the outdoor ambient temperature, the battery power W (kmh), and the cell temperature, determines the average discharge power P (kw) in the past period of time, and can determine the dischargeable time t (h) according to the battery power and the average discharge power. By multiplying the dischargeable time by the average vehicle speed V (km / h) in the past period of time, the remaining mileage S (km) under each thermal management strategy can be determined. For example, S = (W / P) * V. The average discharge power under different thermal management strategies can be obtained by looking up a table according to the outdoor ambient temperature and the cell temperature, that is, the average discharge power under different thermal management strategies can be determined, and then the remaining mileage under different thermal management strategies can be determined.

[0093] Exemplarily, the vehicle operation parameters may include the average discharge current. During vehicle driving, the remaining battery capacity Q (Ah) can be determined according to the battery power. And according to the outdoor ambient temperature, the remaining battery capacity, and the cell temperature, the average discharge current I (A) over a past period of time can be determined. According to the remaining battery capacity and the average discharge current, the dischargeable time t (h) can be determined. By multiplying the dischargeable time by the average vehicle speed V (km / h) over the past period of time, the cruising range S (km) under each thermal management strategy can be determined. For example, S = (Q / P) * V. The average discharge current under different thermal management strategies can be obtained by looking up a table according to the outdoor ambient temperature and the cell temperature, that is, the average discharge current under different thermal management strategies can be determined, and then the cruising range under different thermal management strategies can be determined.

[0094] Exemplarily, the vehicle operation parameters may include the power consumption per 100 kilometers. During vehicle driving, the cruising range S (km) can be obtained according to the power consumption per 100 kilometers E (kwh / 100km) of the vehicle under the standard cruising condition and the battery power W (kmh). For example, S = (W / E) * 100. The power consumption per 100 kilometers under different thermal management strategies can be obtained by looking up a table according to the outdoor ambient temperature and the cell temperature, that is, the power consumption per 100 kilometers under different thermal management strategies can be determined, and then the cruising range under different thermal management strategies can be determined. Among them, the standard cruising condition can be NEDC (New European Driving Cycle), or CLTC (China Light Vehicle Test Cycle).

[0096] In summary, the mileage corresponding to multiple thermal management strategies is obtained through the acquisition module, and then the mileage information of the target thermal management strategy is determined by the determination module according to the mileage corresponding to the multiple thermal management strategies, and the control module controls the display device (such as the vehicle display screen) to display the mileage information for the user to choose. The user decides whether to select the target thermal management strategy according to actual needs and in combination with the mileage information, and issues a control instruction. After receiving the control instruction, the control module responds to the control instruction and controls the vehicle thermal management strategy according to the control instruction. For example, when the user selects the target thermal management strategy, the control module controls the vehicle to switch to the target thermal management strategy; for another example, when the user does not select the target thermal management strategy, the control module controls the vehicle to keep the current thermal management strategy unchanged. Thus, the mileage information is displayed on the display device to perform human-computer interaction, improve user experience, and control the thermal management strategy according to the control instruction, reduce energy waste caused by misheating, and improve the overall efficiency of the vehicle.
