Description

Technical Field

[0001] This application relates to the field of vehicle thermal management technology, and in particular to a method, apparatus, medium, equipment and vehicle for performing vehicle driving thermal management. Background Technology

[0002] The vehicle's thermal management system connects thermal management components through piping and uses a cooling medium to exchange heat between these components and the external environment, ensuring they operate within their optimal temperature range. The vehicle controller collects the temperatures of the thermal management components within the system and controls the water pumps and fans to achieve heat exchange, bringing the vehicle's powertrain or other thermal management components to thermal equilibrium.

[0003] Current thermal management control strategies are all 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 strategy for thermal management is inherently lagging and lacks foresight regarding subsequent vehicle actions. For instance, if a vehicle is exiting a highway and entering a service area, but the thermal management system continues to operate at high power, some cooling output will be lost, thus affecting the vehicle's range. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a vehicle driving thermal management execution method, device, medium, equipment and vehicle to solve the problem of lag in the existing vehicle driving thermal management execution methods.

[0005] To achieve the above objectives, this application provides a vehicle thermal management execution method, applied in a vehicle thermal management system. The thermal management system includes a low-power operation mode and a non-low-power operation mode. The method includes:

[0006] The vehicle's driving scenario information is obtained. In response to determining that the vehicle's current driving scenario is the target lane, the vehicle's speed information is obtained, wherein the target lane is the driving lane between the highway and the service area.

[0007] In response to determining that the vehicle speed information is less than a first preset value, the temperature of the thermal management component in the thermal management system is obtained;

[0008] In response to determining that the temperature of the thermal management component is less than or equal to a preset temperature value, an execution signal corresponding to the low-power operation mode is sent to the thermal management system so that the thermal management system operates in the low-power operation mode.

[0009] Furthermore, obtaining the vehicle's current driving scenario information includes:

[0010] The vehicle's first estimated mileage is determined based on the distance between its current location and its destination.

[0011] If the first estimated mileage is greater than the second preset value, the vehicle's driving scenario information is obtained.

[0012] Further, the step of obtaining the temperature of the thermal management component in the thermal management system in response to determining that the vehicle speed information is less than a first preset value includes:

[0013] The vehicle's second estimated mileage is determined based on its current location and the distance between the service area;

[0014] If the second estimated driving distance is less than the third preset value and the vehicle speed information is less than the first preset value, the temperature of the thermal management component in the thermal management system is obtained.

[0015] Furthermore, the method for determining the preset temperature value includes:

[0016] Based on the upper limit temperature value of the thermal management component, the second estimated driving range, and vehicle speed information, the preset temperature value of the thermal management component that enables low-power operation mode is determined.

[0017] Further, the step of sending an execution signal corresponding to the low-power operation mode to the thermal management system to cause the thermal management system to operate in the low-power operation mode includes:

[0018] Detect the temperature of thermal management components;

[0019] In response to determining that the temperature of the thermal management component is below the upper limit temperature value, the thermal management system maintains a low-power operation mode.

[0020] In response to determining that the temperature of the thermal management component is greater than or equal to the upper limit temperature value, a switching signal is sent to the thermal management system to switch the low-power operation mode of the thermal management system to a non-low-power operation mode.

[0021] Furthermore, the non-low power operation mode includes a first preset operation mode and a second preset operation mode, wherein the output power consumption of the first preset operation mode is greater than the output power consumption of the second preset operation mode.

[0022] The step of sending an execution signal corresponding to the low-power operation mode to the thermal management system to cause the thermal management system to operate in the low-power operation mode includes:

[0023] Acquire temperature information of thermal management components and ambient temperature;

[0024] In response to determining that the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature information is greater than or equal to the fourth preset value, a switching signal is sent to the thermal management system to switch the low power operation mode of the thermal management system to the first preset operation mode.

[0025] In response to determining that the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature information is less than the fourth preset value, a switching signal is sent to the thermal management system to switch the low power operation mode of the thermal management system to the second preset operation mode.

[0026] Based on the same inventive concept, this application also provides a vehicle thermal management actuator, comprising:

[0027] The information acquisition module is configured to acquire vehicle driving scenario information. In response to determining that the current driving scenario of the vehicle is the target lane, the module acquires the vehicle speed information, wherein the target lane is the driving lane between the highway and the service area.

[0028] The detection module is configured to acquire the temperature of the thermal management components in the thermal management system in response to determining that the vehicle speed information is less than a first preset value.

[0029] The execution module is configured to send an execution signal corresponding to the low-power operation mode to the thermal management system in response to determining that the temperature of the thermal management component is less than or equal to a preset temperature value, so that the thermal management system operates in the low-power operation mode.

[0030] Based on the same inventive concept, this application also provides a computer-readable storage medium storing computer instructions for causing the computer to perform the thermal management execution method as described in any of the preceding claims.

[0031] Based on the same inventive concept, this application also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor, when executing the computer program, implements the method described in any of the preceding claims.

[0032] Based on the same inventive concept, this application also provides a vehicle, including the thermal management actuator or storage medium as described above or the electronic device as described above.

[0033] As can be seen from the above, the vehicle driving thermal management execution method provided in this application obtains the vehicle's driving scenario information. When it is determined that the vehicle is on the target lane, it is judged that the vehicle is traveling on the highway towards the service area. Based on this, when the vehicle speed is less than a first preset value, the temperature of the thermal management component is obtained. If the temperature of the thermal management component is less than or equal to the preset temperature value, it means that the temperature of the thermal management component will not exceed the upper limit temperature value during the period when the vehicle is traveling towards the service area. At this time, the thermal management system is operated in a low-power operation mode. After the vehicle arrives at the service area, the thermal management component can be naturally cooled to room temperature using the ambient temperature. This avoids the loss of ineffective output energy due to high-power cooling during vehicle operation, effectively reducing the execution energy consumption of the thermal management system during driving and improving the vehicle's range.

[0039] 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.

[0040] 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 "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

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.

[0041] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0042] One or more embodiments of this application provide a vehicle driving thermal management execution method, which is applied in a vehicle thermal management system.

[0043] Here, the vehicle thermal management system operates in two modes: a low-power mode and a non-low-power mode. The thermal management system includes thermal management components that require cooling, such as motor-related components or battery components. The cooling methods for these components can be achieved through fan cooling or coolant circulation loops, which will not be elaborated upon in this application.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, the vehicle driving thermal management execution method of this application includes:

[0045] S101, obtain vehicle driving scenario information; in response to determining that the current driving scenario of the vehicle is the target lane, obtain vehicle speed information, wherein the target lane is the driving lane between the highway and the service area.

[0046] In step S101 above, the vehicle driving scenario information refers to the lane information of the vehicle currently driving. The vehicle central control can obtain the vehicle driving scenario information by means of navigation (such as GPS, Beidou satellite positioning) to obtain the vehicle location. When the obtained vehicle location is on the target lane, the vehicle central control determines that the vehicle needs to temporarily stop in the service area and obtains the vehicle's current speed information in this scenario.

[0047] It should be noted that since the vehicle position is changed from the highway to the target lane, the vehicle speed is reduced compared to the highway speed. However, due to the medium-to-high speed driving factors, the vehicle's thermal management components heat up faster. If the thermal management system is rashly controlled to operate at low power at this time, it will lead to unstable temperature control of the thermal management components and create safety hazards. Therefore, it is necessary to make a comprehensive judgment based on the vehicle speed information before continuing with the subsequent steps of this application.

[0048] Furthermore, prior to step S101, the vehicle's central control unit can first determine whether the vehicle is located on a highway. Only when the vehicle is traveling in the target lane of the highway will the vehicle driving thermal management execution method described in this application be performed. The target lane can be a ramp from the highway to a service area, or other transitional guidance lanes between the highway and the service area; this embodiment only provides an example.

[0049] In some embodiments, step S101 includes:

[0050] S1011, determine the vehicle's first estimated mileage based on the distance between the vehicle's current location and its destination;

[0051] S1012, in response to the first estimated driving mileage being greater than the second preset value, the vehicle's driving scenario information is obtained.

[0052] In steps S1011 and S1012 above, for example, the second preset value is 5km. After obtaining the vehicle's current location and destination information through navigation (such as GPS, Beidou satellite positioning), the vehicle's central control unit determines the vehicle's first estimated driving mileage and compares the first estimated driving mileage with the second preset value. When the first estimated driving mileage is greater than the second preset value (5km) and the vehicle is located in the target lane, it is determined that the driver may have the intention to temporarily stop. Then, the subsequent thermal management execution method is performed in combination with the vehicle's driving scenario information.

[0053] Furthermore, in some embodiments, step S101 includes:

[0054] S1013, determine the vehicle's second estimated mileage based on the vehicle's current location and the distance between the service area;

[0055] S1014, in response to the second estimated driving mileage being less than the third preset value and the vehicle speed information being less than the first preset value, the temperature of the thermal management component in the thermal management system is obtained.

[0056] In steps S1013 and S1014 above, after the vehicle central control unit determines that the vehicle is located in the target lane, it can also determine the second estimated driving distance by combining the distance between the vehicle's current position and the service area. For example, the third preset value can be 500m. When the distance between the vehicle's current position and the service area, that is, the second estimated driving distance, is less than 500m, the vehicle speed information is then obtained. Setting this step can improve the accuracy of the vehicle central control unit in determining the vehicle's position, thereby helping to further improve the judgment accuracy of the vehicle central control unit.

[0057] It should be noted that the first estimated mileage in this application should be greater than the second estimated mileage, and the second preset value should be greater than the third preset value, so that the vehicle's central control unit can more accurately determine the vehicle's driving intention.

[0058] The vehicle thermal management implementation method of this application also includes:

[0059] Step S102: In response to determining that the vehicle speed information is less than a first preset value, the temperature of the thermal management component in the thermal management system is obtained.

[0060] In the above steps, for example, the first preset value is 70km / h. When the detected vehicle speed information is less than 70km / h, since the vehicle has switched from the highway to the target lane and is driving towards the service area, the vehicle speed will not increase significantly. Although the temperature of the vehicle's thermal management components will increase with the increase of driving time, the increase is controllable. In this scenario, the temperature of the thermal management components in the thermal management system is obtained.

[0061] Of course, the first preset value described in this application is only an example. Depending on the different driving factors such as ambient temperature, whether the vehicle is driving on a flat road, uphill, or downhill, the first preset value can also be other values. For example, when the vehicle is driving uphill continuously in the target lane, the thermal management component outputs a larger power and heats up faster, so the first preset value is reduced accordingly.

[0062] In step S102 above, the thermal management component refers to the object used by the vehicle thermal management system for cooling, including motor-related components, battery components, etc. The temperature of the thermal management component can be obtained by directly acquiring the temperature through a temperature sensor installed on the corresponding thermal management component, or by collecting the temperature of the coolant in the liquid circulation loop, and determining the temperature of the corresponding thermal management component by the temperature of the coolant flowing through the thermal management component.

[0063] In some embodiments, the vehicle driving thermal management execution method of this application further includes:

[0064] S103, in response to determining that the temperature of the thermal management component is less than or equal to a preset temperature value, an execution signal corresponding to the low-power operation mode is sent to the thermal management system so that the thermal management system operates in the low-power operation mode.

[0065] In step S103 above, the vehicle's central control unit can determine the preset temperature value at which the thermal management component can operate with low power consumption based on the upper limit temperature value of the thermal management component, the second estimated driving mileage, and vehicle speed information. The upper limit temperature value of the thermal management component refers to the maximum temperature that the motor-related components or battery components can reach without affecting their lifespan or working performance. Exceeding the upper limit temperature value will seriously affect the working life of the thermal management component. Here, the upper limit temperature value can be obtained through the attributes of the thermal management component itself.

[0066] In some embodiments, the preset temperature value of the thermal management component refers to a value lower than the upper limit temperature value. For example, when a vehicle is traveling at a certain speed, the upper limit temperature value of the thermal management component minus the expected temperature rise during this time is the preset temperature value, as shown in the following formula:

[0067] t = Tm;

[0068] Where t is the preset temperature value, T is the upper limit temperature value of the thermal management component, and m is a constant.

[0069] In the above formula, the constant *m* is related to the vehicle's estimated mileage and speed. Since there is no congestion on the target lane, the longer the estimated mileage, the greater the estimated temperature rise during the journey, the larger the constant *m*, and the smaller the preset temperature value of the thermal management component. Similarly, the faster the vehicle speed, the greater the estimated temperature rise during the journey, the larger the constant *m*, and the smaller the preset temperature value of the thermal management component. In short, the vehicle's central control system needs to determine the time it takes for the thermal management component to rise from the preset temperature value to the upper limit temperature value based on the vehicle's estimated mileage and speed, and to ensure that the temperature of the thermal management component is less than or equal to the upper limit temperature value after the vehicle arrives at the service area. This setting can further optimize the vehicle's output power consumption and reduce unnecessary losses when the vehicle approaches the service area, thereby improving the vehicle's range. For example, *m* is set to 10°C.

[0070] It should be noted that in some embodiments, the temperature of the thermal management component may be multiple temperatures of multiple different thermal management components. When multiple temperatures of multiple different thermal management components are obtained, the highest temperature among the multiple temperatures is taken as the standard, so as to ensure that the upper limit temperature value is not reached after the thermal management component operates at low power at the highest temperature. When the temperature of the thermal management component is obtained by the temperature of the coolant in the liquid circulation loop, the temperature of the coolant can be taken directly. Generally speaking, the temperature of the coolant will be slightly lower than the temperature of the thermal management component.

[0071] In some embodiments, during step S103 above, the thermal management system operates in a low-power mode, including the following two scenarios:

[0072] (1) Sending an execution signal corresponding to the low-power operation mode to the liquid circulation loop of the thermal management system to reduce the flow rate or cooling power of the coolant in the liquid circulation loop; and / or,

[0073] (2) Send an execution signal corresponding to the low power operation mode to the cooling fan of the thermal management system to reduce the cooling fan rotation speed or turn off the cooling fan.

[0074] The above describes two modes of low-power operation of the thermal management system. In some embodiments, to protect relevant components, the coolant in the liquid circulation loop cannot be empty. Therefore, the low-power operation mode of the thermal management system includes using a control pump to reduce the coolant flow rate in the liquid circulation loop to a minimum. Furthermore, the low-power operation mode also includes reducing the coolant cooling power and cooling fan output power to 20% of their original rated power.

[0075] In some embodiments, after step S103, the method further includes:

[0076] S104, detects the temperature of the thermal management components;

[0077] S105, in response to determining that the temperature of the thermal management component is lower than the upper limit temperature value, the thermal management system maintains a low-power operation mode.

[0078] S106, in response to determining that the temperature of the thermal management component is greater than or equal to the upper limit temperature value, a switching signal is sent to the thermal management system to switch the low power operation mode of the thermal management system to a non-low power operation mode.

[0079] The above steps are based on the scenario where the thermal management system is already operating at low power. When the vehicle is in motion, the temperature of the thermal management components is continuously detected and acquired. When the detected temperature of the thermal management components is lower than the upper limit temperature value, it proves that the temperature of the vehicle's thermal management components is higher than the preset temperature value but has not reached the upper limit temperature value that affects the lifespan. At this time, the low power operation mode can continue to be maintained. When the detected temperature of the thermal management components is greater than or equal to the upper limit temperature value, it proves that the temperature of the thermal management components is too high and has reached a high temperature environment that affects the working lifespan and working performance. Therefore, it is necessary to switch the thermal management system to a non-low power operation mode to cool down the thermal management components as soon as possible.

[0080] The above settings can further reduce the energy consumption of thermal management. At the same time, by using tiered scenario settings to adopt different execution strategies for the thermal management system, the intelligent and user-friendly operation of the thermal management system can be guaranteed, and the judgment logic of the thermal management system can be optimized.

[0081] It should be noted that the non-low power operation mode of the thermal management system refers to a state with higher output power compared to the low power operation mode, that is, a higher flow rate or cooling power of the coolant in the liquid circulation loop, or a faster rotation speed of the cooling fan.

[0082] In some embodiments, the non-low power operation mode includes a variety of different forms of thermal management operation mode. For example, the non-low power operation mode includes a first preset operation mode and a second preset operation mode, wherein the output power consumption of the first preset operation mode is greater than the output power consumption of the second preset operation mode.

[0083] The first preset operating mode corresponds to the thermal management cooling operating mode under full power and high power consumption. In this state, the water pump output power of the liquid circulation loop in the thermal management system is at its maximum, and the cooling fan is turned on and running at high speed. The second preset operating mode corresponds to the thermal management cooling operating mode under medium power and medium power consumption. In this state, the water pump output power of the thermal circulation loop in the thermal management system is 50% of the full power, and the fan is turned off.

[0084] The first and second preset operating modes mentioned above are only examples. For different driving scenarios, the first and second preset operating modes can be adjusted. For example, in the first preset operating mode, the water pump output power of the liquid circulation loop in the thermal management system is 50% of the full power, and the cooling fan is turned on and running at high speed; in the second preset operating mode, the water pump output power of the liquid circulation loop in the thermal management system is maintained at the minimum value, and the cooling fan is turned on and running at high speed. As long as multiple thermal management operating modes with different output power are set, it is possible.

[0085] By setting multiple thermal management operating modes with different output power consumption, it is possible to optimize and adapt to different driving scenarios in a targeted manner, so as to reduce the overall vehicle output power consumption and improve the vehicle's range as much as possible while meeting the vehicle's driving requirements.

[0086] Based on the above description, in some embodiments, the method further includes the following after step S103:

[0087] S107, acquire temperature information of thermal management components and ambient temperature;

[0088] S108, in response to determining that the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature information is greater than or equal to the fourth preset value, a switching signal is sent to the thermal management system to switch the low power operation mode of the thermal management system to the first preset operation mode.

[0089] S109, in response to determining that the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature information is less than the fourth preset value, a switching signal is sent to the thermal management system to switch the low power operation mode of the thermal management system to the second preset operation mode.

[0090] In the above steps, for example, the fourth preset value is 5°C. When the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature is greater than or equal to 5°C, the thermal management component's cooling effect through external airflow is limited due to the high ambient temperature. Therefore, the thermal management system needs to use the higher power consumption of the first preset operating mode to cool the thermal management component. When the temperature of the thermal management component is greater than or equal to the upper limit temperature value and the ambient temperature is less than 5°C, the thermal management component is sufficiently cooled by natural airflow from the surrounding environment due to the low ambient temperature. Therefore, the thermal management system can use the lower power consumption of the second preset operating mode to cool the component. In summary, the goal is to minimize the output power consumption of the vehicle's thermal management system while ensuring that the temperature of the thermal management component can be quickly reduced to below the upper limit temperature value.

[0091] In summary, such as Figure 2 As shown, an exemplary description of the vehicle driving thermal management execution method provided in this application is as follows:

[0092] When the vehicle is in motion, the vehicle's central control unit determines whether the vehicle is on a highway based on navigation information. When the vehicle is on a highway, it determines whether the first estimated distance between the vehicle and the destination is less than 500m based on navigation information or other data. When the central control unit determines that the first estimated distance is greater than 500m, it continuously monitors the vehicle's driving scenario information and obtains the vehicle's speed information when it determines that the current driving scenario is the target lane. When the vehicle speed is less than 70km / h, it obtains the temperature of the thermal management components. When the temperature of the thermal management components is less than or equal to a preset temperature value, the central control unit controls the thermal management system to operate in a low-power mode.

[0093] The vehicle's central control unit continuously acquires the temperature of the thermal management components in low-power operation mode. When the temperature of the thermal management components is greater than or equal to the upper limit temperature value, and the acquired ambient temperature information is greater than 5°C, the central control unit controls the thermal management system to be in the first preset operation mode (full power, high power consumption operation mode). When the temperature of the thermal management components is greater than or equal to the upper limit temperature value, and the acquired ambient temperature information is less than or equal to 5°C, the central control unit controls the thermal management system to be in the second preset operation mode (medium power, medium power consumption operation mode).

[0094] 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.

[0095] It should be noted that the above description describes some embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result.
