[0002] The current research and development direction for new energy vehicles is to reduce vehicle energy consumption in order to improve vehicle range.

[0003] For new energy vehicles, many factors influence their energy consumption, and the energy consumption of the thermal management system is one of them. Existing thermal management system control strategies are based on current temperature data for powertrain thermal management. For example, the vehicle controller determines whether to cool or heat the powertrain based on its current temperature. However, this passive response capability of thermal management has a lag. For instance, when the vehicle is about to park, the cooling or heating load of the vehicle's thermal management system decreases, and the system's execution capability also decreases accordingly. If the thermal management system continues to operate at high power based on the current temperature, it will lead to higher energy consumption, wasting energy and reducing the vehicle's range.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0045] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0046] In related technologies, the heating and cooling subsystems of the thermal management system of new energy vehicles are both based on the current temperature data for thermal management. The components in the thermal management system operate according to the required power value corresponding to the current temperature. When the vehicle is about to be parked, the cooling or heating load of the vehicle management system will decrease. The thermal management system will have a lag. If the components in the thermal management system still operate according to the required power value corresponding to the current temperature, it will lead to excessive energy consumption of the thermal management system, resulting in some energy waste and reducing the vehicle's range.

[0047] In the embodiments of this application, the vehicle-mounted system acquires vehicle and road information, predicts the vehicle's driving situation in advance, and automatically determines whether the vehicle meets the low-power operation conditions of the thermal management system. If the vehicle-mounted system automatically detects that the vehicle meets the low-power operation conditions of the thermal management system and that the thermal management system is in an on state, it acquires the control mode of the thermal management system to determine whether the vehicle control mode is a heating control mode or a cooling control mode. When the control mode is a heating control mode, at least some of the heating components are turned off or their power is reduced, so that the heating subsystem of the thermal management system enters a low-power operation mode. The thermal management system entering a low-power operation mode reduces the power consumption of the vehicle's thermal management system, thereby improving the vehicle's range.

[0048] The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0049] refer to Figure 1A control method for a thermal management system, the thermal management system comprising a heating subsystem and a cooling subsystem, wherein the heating subsystem is equipped with multiple heating components and the cooling subsystem is equipped with multiple cooling components, the method comprising:

[0050] Step S100: Obtain vehicle information and road information.

[0051] In this step, during vehicle operation, the vehicle's infotainment system acquires vehicle and road information, predicts the vehicle's next driving conditions in advance, and automatically determines whether the vehicle meets the low-power operating conditions of the thermal management system, so that the vehicle's thermal management system can operate at low power and improve the vehicle's range.

[0052] Step S200: In response to the vehicle information and road information meeting the low-power operation conditions of the thermal management system and the thermal management system being in an on state, the control mode of the thermal management system is obtained, the control mode including: heating control mode and cooling control mode.

[0053] In this step, when the vehicle system automatically detects that the vehicle meets the low-power operation conditions of the thermal management system and that the thermal management system is in the on state, it obtains the control mode of the thermal management system to determine whether the vehicle control mode is heating control mode or cooling control mode.

[0054] Step S300: In response to the control mode of the thermal management system being heating control mode, at least some of the heating components are turned off or the power of at least some of the heating components is reduced so that the heating subsystem enters a low-power operation mode.

[0055] In this step, when the control mode is heating control mode, at least some of the heating components are turned off or the power of at least some of the heating components is reduced, so that the heating subsystem of the thermal management system enters a low-power operation mode, reducing the power consumption of the thermal management system and thus improving the vehicle's range.

[0056] Step S400: In response to the thermal management system being in cooling control mode, at least some of the cooling components are turned off or the power of at least some of the cooling components is reduced so that the cooling subsystem enters a low-power operation mode.

[0057] In this step, when the control mode is cooling control mode, at least some cooling components are turned off or the power of at least some cooling components is reduced, so that the cooling subsystem of the thermal management system enters a low-power operation mode, reducing the power consumption of the thermal management system and thus improving the vehicle's range.

[0058] Specifically, the vehicle system determines whether the vehicle meets the low-power operation conditions of the thermal management system based on vehicle and road information. If it does, it obtains the current control mode of the vehicle and enables the mode to operate in a low-power mode to achieve low-power operation of the thermal management system, thereby improving the vehicle's range and solving the problem of high energy consumption of the thermal management system in the prior art, which reduces the vehicle's range.

[0059] In some embodiments, before obtaining vehicle information and road information in step S100, it is necessary to obtain the current driving scenario of the vehicle; specifically including:

[0060] The current driving scenario of the vehicle is obtained, including high-speed driving scenarios and non-high-speed driving scenarios;

[0061] If the vehicle is currently in a non-high-speed driving scenario, then vehicle information and road information are obtained.

[0062] Specifically, since different driving scenarios correspond to different low-power operating conditions, the vehicle's driving scenario is obtained, and the vehicle information and road information in that scenario are obtained based on the driving scenario, and then the vehicle information and road information in that scenario are further detected.

[0063] Furthermore, high-speed driving scenario information refers to the vehicle traveling on a highway, while non-high-speed driving scenario information refers to the vehicle not traveling on a highway. The current driving scenario information, vehicle information, and road information can be obtained through navigation (e.g., GPS, BeiDou satellite positioning). When the vehicle's location is on a highway, it is determined that the vehicle is currently in a high-speed driving scenario. At this time, due to the speed of vehicles on highways, the vehicle's thermal management components heat up quickly. Low-power operation of the thermal management system can lead to unstable temperature control of the thermal management components, creating safety hazards. Therefore, the low-power operation mode in this application can only be used in non-high-speed driving scenarios, i.e., when the vehicle is not on a highway.

[0064] In some embodiments, in step S200, the vehicle information includes vehicle location, vehicle speed, and cabin temperature, and the road information includes destination location; the vehicle information and road information can be determined to meet the low-power operation conditions of the thermal management system in the following ways:

[0065] If the vehicle information and road information simultaneously meet the first preset condition, the second preset condition and the third preset condition, then it is determined that the vehicle meets the low-power operation conditions of the thermal management system.

[0066] The first preset condition is that the time it takes for the vehicle to reach the destination is less than a preset time threshold;

[0067] The second preset condition is that the average speed of the vehicle within a preset time period is less than a preset speed threshold.

[0068] When the control mode is the heating control mode, the third preset condition is that the cabin temperature is greater than or equal to the first preset temperature threshold.

[0069] When the control mode is the cooling control mode, the third preset condition is that the cabin temperature is less than the second preset temperature threshold.

[0070] Specifically, by detecting vehicle location, speed, cabin temperature, and destination location, vehicle and road information are analyzed. When the thermal management system is found to meet the low-power operation conditions, it directly enters low-power operation, saving energy and improving the vehicle's range.

[0071] Optionally, the judgment process for the first preset condition is as follows:

[0072] The time it takes for the vehicle to reach its destination is compared with a preset time threshold. If the time it takes for the vehicle to reach its destination is less than the preset time threshold, the vehicle is determined to meet the first preset condition. If the time it takes for the vehicle to reach its destination is greater than or equal to the preset time threshold, the vehicle is determined to not meet the first preset condition.

[0073] The time it takes for the vehicle to reach its destination in the above steps can be obtained through navigation; for example, traffic information and traffic light information in the navigation can be obtained, and the time it takes for the vehicle to reach its destination can be determined based on the traffic information and traffic light information.

[0074] Optionally, the second preset condition judgment process is as follows:

[0075] The preset time period is at least one continuous time period from the start time of vehicle travel to the current time. For example, if the start time of vehicle travel is 10:00 and the current time is 12:00, then the preset time period can be set to 11:20 to 11:50. The vehicle speed within this preset time period is obtained, and the average speed within this preset time period is calculated to obtain the average speed. The average speed is compared with a preset speed threshold. If the average speed is less than the preset speed threshold, then the vehicle is determined to meet the second preset condition. If the average speed is greater than or equal to the preset speed threshold, then the vehicle is determined not to meet the second preset condition.

[0076] Optionally, the third preset condition judgment process is as follows:

[0077] When the control mode is heating control mode, the current cabin temperature is obtained and compared with a first preset temperature threshold. If the cabin temperature is greater than or equal to the first preset temperature threshold, the vehicle is determined to meet the third preset condition; if the cabin temperature is less than the first preset temperature threshold, the vehicle is determined not to meet the third preset condition.

[0078] When the control mode is the cooling control mode, the current cabin temperature is obtained and compared with the second preset temperature threshold. If the cabin temperature is less than the second preset temperature threshold, the vehicle is determined to meet the third preset condition; if the cabin temperature is greater than or equal to the second preset temperature threshold, the vehicle is determined not to meet the third preset condition.

[0079] In some embodiments, in step 300, the heating components are heaters (i.e., PTC), heating water pumps, and / or blowers; at least some of the heating components are shut down or their power is reduced in the following manner:

[0080] Turn off the heater, or reduce the power value of the heater to a preset heater power value; and / or,

[0081] Reduce the power value of the heating water pump to a preset heating water pump power value; and / or,

[0082] The power value of the blower is reduced to the preset blower power value.

[0083] Specifically, since the heater continuously heats the circulating water during the heating process, and the circulating water is hot, the heater can be turned off or its power value can be reduced to a preset heater power value, and the power of the heating water pump can also be reduced to a preset heating water pump power value. The heating water pump circulates the circulating water according to the preset heating water pump power value. Then, the power value of the blower is reduced to a preset blower power value, and the blower blows the heat emitted by the circulating water into the vehicle cabin according to the preset blower power value, thus achieving low-power operation of the heating subsystem and improving the vehicle's range.

[0084] For example, the preset heating water pump power value P can be 15KW; the preset blower power value can be 0.55KW.

[0085] Based on the above example, after the heater is turned off, the following may also be included:

[0086] Obtain the cabin temperature of the vehicle;

[0087] In response to the cabin temperature being lower than a third preset temperature threshold, the heater is activated and its power value is adjusted to a preset heater power value.

[0088] Specifically, after the heater is turned off, the heat load of the heating subsystem decreases, and the cabin temperature will drop. The current cabin temperature is obtained, and it is determined whether the current cabin temperature is lower than the third preset temperature threshold (the third preset temperature threshold is lower than the first preset temperature threshold). If it is lower than the third preset temperature threshold, it means that the current cabin temperature is too low, and the heater needs to be turned on for heating. The heater operates according to the preset heater power value, which is lower than the power value required by the heater for the temperature set by the user. This achieves low power consumption operation of the heater, while still maintaining the low power consumption operation mode of the heating subsystem.

[0089] In some embodiments, in step 400, the cooling component is a compressor, a battery water pump, and / or a blower; the cooling component is shut down or its power is reduced at least in part by the following methods:

[0090] Turn off the compressor and the battery water pump; and / or,

[0091] Adjust the blower speed to the preset blower speed.

[0092] Specifically, when the vehicle is nearing its destination, the system checks if the cabin temperature is below a second preset temperature threshold. If the cabin temperature is below this threshold, the refrigeration subsystem can operate at low power, by shutting down the compressor and battery water pump. Shutting down the compressor shuts down the cabin's refrigeration circuit, and shutting down the battery water pump shuts down the battery's refrigeration circuit, thus disabling battery cooling requests. By shutting down the compressor and battery water pump, the blower speed is lowered to a preset setting, allowing only the blower to blow air into the cabin. Because the compressor and battery water pump are off, and the blower speed is lowered, the power consumption of the refrigeration subsystem is reduced, achieving low-power operation and improving the vehicle's range.

[0093] Based on the above example, after shutting down at least part of the cooling components or reducing the power of at least part of the cooling components, the method may further include:

[0094] Obtain the cabin temperature of the vehicle;

[0095] In response to the cabin temperature being greater than or equal to a second preset temperature threshold, the compressor is started and its power value is reduced to a preset compressor power value.

[0096] Specifically, by shutting down or reducing the power of at least some of the refrigeration components, the cooling load of the refrigeration subsystem decreases, and the cabin temperature rises. Therefore, the current cabin temperature is obtained, and it is determined whether the current cabin temperature is greater than or equal to a second preset temperature threshold. If it is greater than or equal to the second preset temperature threshold, it indicates that the current cabin temperature is too high. Only the cabin is refrigerated, so the cabin refrigeration circuit is activated. Since the compressor is needed for cooling, it is started. The compressor operates according to a preset compressor power value, which is less than the power value required by the compressor at the user-set temperature. This achieves low-power operation of the compressor and improves the vehicle's range.

[0097] In some embodiments, the thermal management system control method further includes:

[0098] In response to receiving a temperature change command in the current control mode, the changed temperature value in the temperature change command is obtained;

[0099] In response to the change temperature value being greater than or equal to the first preset temperature threshold or the change temperature value being less than the second preset temperature threshold, the thermal management system is controlled to stop executing the low-power operation mode and control the temperature change according to the current control mode.

[0100] Specifically, taking the current control mode as the heating control mode as an example, when the user resets the temperature of the heating control mode, the vehicle system receives a temperature change command, obtains the changed temperature value in the temperature change command, and determines whether the changed temperature value is greater than or equal to the first preset temperature threshold. If the changed temperature value is greater than or equal to the first preset temperature threshold, it means that the user feels that the cabin temperature is too low and needs to be increased. Therefore, the low-power operation is stopped, and heating continues according to the normal heating control mode. The normal heating control mode is as follows: the heating components execute according to the required power corresponding to the temperature value set by the user, so as to realize the flexible control of the thermal management system and provide users with a better experience.

[0101] Taking the current control mode as an example of the cooling control mode, when the user resets the temperature of the cooling control mode, the vehicle system receives a temperature change command, obtains the changed temperature value in the temperature change command, and determines whether the changed temperature value is less than the second preset temperature threshold. If the changed temperature value is less than the second preset temperature threshold, it means that the user feels that the temperature in the cabin is too high and needs to be lowered. Therefore, the low-power operation is stopped, and the cooling continues to be carried out in the normal cooling control mode. The normal cooling control mode is as follows: the cooling components execute according to the required power based on the temperature value set by the user, so as to realize the flexible control of the thermal management system and provide the user with a better experience.

[0102] In some embodiments, determining the on / off state of the thermal management system can be achieved by determining the on / off state of the heating subsystem or the cooling subsystem, specifically as follows:

[0103] In response to detecting that the heating subsystem is in an on state or the cooling subsystem is in an on state, the thermal management system is determined to be in an on state.

[0104] It should be noted that the embodiments of this application can also be further described in the following ways:

[0105] Reference Figure 2 A control method for a thermal management system, comprising:

[0106] When the vehicle's thermal management system is in heating control mode:

[0107] In navigation mode, the vehicle's infotainment system acquires the vehicle's current driving scenario and determines whether it is a non-high-speed driving scenario. If the current driving scenario is a non-high-speed driving scenario, it acquires the vehicle's position, speed, cabin temperature, and destination location. It calculates the time it takes for the vehicle to reach the destination as 2 minutes and compares this time with a preset time threshold (e.g., 3 minutes). If the time is less than the preset time threshold, the vehicle meets the first preset condition. The system then acquires the vehicle's speed within a preset time period (e.g., 11:20 to 11:50) and calculates the average speed during this period (e.g., 10 km / h). This average speed is compared with a preset speed threshold (e.g., 15 km / h). If the average speed is less than the preset threshold, the vehicle meets the second preset condition. The vehicle cabin temperature (exemplarily 20°C) is compared with a first preset temperature threshold (exemplarily 10°C). If the cabin temperature is greater than the first preset temperature threshold, the vehicle is determined to meet the third preset condition. If both vehicle and road information meet the first, second, and third preset conditions simultaneously, the vehicle is determined to meet the low-power operation conditions of the thermal management system. The heater is then turned off, the power of the heating water pump is reduced to 15KW, and the power of the blower is reduced to 0.55KW. The blower is used to blow hot air into the cabin, enabling the heating subsystem to operate at low power. When the cabin temperature is less than the third preset temperature threshold (exemplarily 5°C), it indicates that the current cabin temperature is too low and the heater is needed. The heater is then activated, operating at 50% of the power required for the temperature set by the user. The blower blows hot air into the cabin, maintaining low-power operation until the destination is reached.

[0108] If the user resets the heating control mode and changes the temperature to 15℃, and the changed temperature is greater than the first preset temperature threshold, it means that the user feels the cabin temperature is too low and needs to increase the temperature. In this case, the low-power operation will stop, and the heating components will continue to operate according to the power value required by the heater at the user-set temperature.

[0109] When the vehicle's thermal management system is in cooling control mode:

[0110] In navigation mode, the vehicle's infotainment system acquires the vehicle's current driving scenario and determines whether it is a non-high-speed driving scenario. If the current driving scenario is a non-high-speed driving scenario, it acquires the vehicle's position, speed, cabin temperature, and destination location. The system calculates the time it takes for the vehicle to reach the destination as 2 minutes and compares this time with a preset time threshold (e.g., 3 minutes). If the time is less than the preset time threshold, the vehicle meets the first preset condition. The system acquires the vehicle's speed within a preset time period (e.g., 11:20 to 11:50) and calculates the average speed during this period (e.g., 10 km / h). This average speed is compared with a preset speed threshold (e.g., 15 km / h). If the average speed is less than the preset threshold, the vehicle meets the second preset condition. Finally, the system compares the cabin temperature (e.g., 5°C) with a first preset temperature threshold (e.g., 6°C). If the cabin temperature is less than the first preset temperature threshold, the vehicle meets the third preset condition. If the vehicle and road information simultaneously meet the first, second, and third preset conditions, then the vehicle is determined to meet the low-power operation conditions of the thermal management system. The compressor and battery water pump are then shut down, and the blower speed is lowered to level one, enabling the cooling subsystem to operate at low power. If the cabin temperature exceeds the second preset temperature threshold, it indicates that the current cabin temperature is too high and the compressor needs to cool the vehicle. The compressor is then started, operating at 50% of the power required for the user-set temperature, to provide cooling until the destination is reached.

[0111] If the user resets the heating control mode and changes the temperature value to 3°C, and the changed temperature value is less than the second preset temperature threshold, it means that the user feels that the temperature in the cabin is too high and needs to lower the temperature. In this case, the low-power operation will stop, and the cooling components will continue to operate according to the power value required by the compressor at the user-set temperature.

[0112] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result.
