Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle and its control method, apparatus and readable storage medium. Background Technology

[0002] Currently, as the automotive industry moves towards electrification, intelligence, and high performance, consumers are increasingly demanding better vehicle handling, comfort, and safety. Active stabilizer bars, as advanced chassis electronic control components, can actively generate anti-roll torque through their actuators, significantly suppressing body roll during cornering and thus improving handling limits and ride comfort. However, when outputting huge torques, the actuators of active stabilizer bars (usually high-power motors or electro-hydraulic servo mechanisms) generate a large amount of heat internally due to copper losses, iron losses, and switching losses of power devices. Excessive temperature can cause component degradation, reducing the reliability and lifespan of the active stabilizer bar. Therefore, existing vehicle control methods suffer from technical problems such as low reliability. Summary of the Invention

Based on the driving mode, determine the target temperature threshold of the active stabilizer bar and the target opening value of the electronic expansion valve; After the active stabilizer bar is activated, obtain the real-time temperature of the active stabilizer bar; When the real-time temperature is greater than the target temperature threshold, the opening degree of the electronic expansion valve is set to the target opening degree value so that the cooling circuit cools the active stabilizer bar.

[0006] The vehicle control method in this embodiment determines the target temperature threshold of the active stabilizer bar and the target opening value of the electronic expansion valve based on the vehicle's driving mode. Then, it compares the real-time temperature of the active stabilizer bar with the target temperature threshold to determine the timing for opening the cooling circuit. When the real-time temperature is greater than the target temperature threshold, the opening of the electronic expansion valve is set to the target opening value so that the cooling circuit cools the active stabilizer bar, ensuring that the active stabilizer bar operates under suitable temperature conditions. This improves the operational reliability of the active stabilizer bar and extends its service life.

[0008] In this embodiment, the vehicle control device determines the target temperature threshold of the active stabilizer bar and the target opening value of the electronic expansion valve based on the vehicle's driving mode. Then, it compares the real-time temperature of the active stabilizer bar with the target temperature threshold to determine the timing for opening the cooling circuit. When the real-time temperature is greater than the target temperature threshold, the opening of the electronic expansion valve is set to the target opening value so that the cooling circuit cools the active stabilizer bar, ensuring that the active stabilizer bar operates under suitable temperature conditions.

It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

The term "two or more" includes two or more cases.

[0016] In some embodiments, such as Figure 1 As shown, an embodiment of this application provides a vehicle control method, including: Step S101: During the vehicle's operation, obtain the vehicle's driving mode. Step S102: Determine the target temperature threshold of the active stabilizer bar and the target opening value of the electronic expansion valve according to the driving mode; Step S103: After the active stabilizer bar is activated, obtain the real-time temperature of the active stabilizer bar. Step S104: When the real-time temperature is greater than the target temperature threshold, the opening degree of the electronic expansion valve is set to the target opening degree value so that the cooling circuit cools the active stabilizer bar.

[0017] In this embodiment, a vehicle control method is proposed, wherein the vehicle includes an active stabilizer bar and an air conditioning system, the air conditioning system includes a cooling circuit for cooling the active stabilizer bar, and an electronic expansion valve is provided on the cooling circuit.

[0018] For example, as an advanced chassis electronic control component, the active stabilizer bar can actively generate anti-roll torque through its actuator, which greatly suppresses the body roll of the vehicle when cornering, thereby improving handling limits and ride comfort.

[0019] For example, a vehicle air conditioner consists of a compressor, condenser, throttling element, evaporator, fan and necessary control components, and is an air conditioning system used to regulate the temperature and humidity inside the vehicle and provide a comfortable environment for the vehicle occupants.

[0020] For example, when the actuator of an active stabilizer bar (typically a high-power motor or electro-hydraulic servo mechanism) outputs huge torque (typically as high as 1000Nm to 1500Nm), a large amount of heat is generated internally due to copper losses, iron losses, and switching losses of power devices. Excessive temperature can cause component degradation, reducing the reliability and lifespan of the active stabilizer bar.

[0021] For example, a branch can be connected in parallel or in series as a cooling circuit on the high-pressure liquid line of the automotive air conditioning system (usually after the receiver-drier and before the evaporator in the cabin). The cooling circuit can cool the actuator of the active stabilizer bar and reduce the overall temperature of the active stabilizer bar.

[0022] For example, an electronic expansion valve is installed at the inlet of the cooling circuit, which can adjust the flow rate of coolant in the cooling circuit. The electronic expansion valve uses the electrical signal generated by the regulated parameter to control the voltage or current applied to the expansion valve, thereby achieving the purpose of regulating the coolant supply. Variable capacity refrigeration systems have a wide range of coolant supply adjustment and require fast adjustment response, which traditional throttling devices (such as thermostatic expansion valves) cannot adequately handle, while electronic expansion valves can well meet these requirements.

[0023] During vehicle operation, the vehicle's driving mode is acquired, where the driving mode represents the vehicle's driving status.

[0024] For example, the driving mode can be comfort mode, sport mode, or off-road mode.

[0025] Comfort mode: responsive throttle, smooth gear shifts, balances comfort and fuel economy, suitable for most daily driving.

[0026] Sport mode: The throttle response is the most sensitive, the shifting is delayed, the power is the strongest but the fuel consumption is higher, suitable for mountain roads or those who want to enjoy driving.

[0027] Off-road mode: This is a mode specifically designed for vehicles to cope with complex road conditions (such as mud, sand, and rocks), which improves passability and stability by adjusting the power, suspension, and differential.

[0028] Based on the driving mode, the target temperature threshold of the active stabilizer bar and the target opening value of the electronic expansion valve are determined. The target temperature threshold is the threshold for judging whether the temperature of the active stabilizer bar is too high, and the target opening value is the valve opening value corresponding to the driving mode.

[0029] For example, the target opening value can be specifically 50%.

[0030] For example, the target temperature threshold can be specifically 100 degrees Celsius.

[0031] For example, if the temperature of the active stabilizer bar exceeds 100 degrees Celsius, it indicates that the active stabilizer bar needs to be cooled down.

[0032] For example, if the temperature of the active stabilizer bar does not exceed 100 degrees Celsius, it indicates that the active stabilizer bar is in good condition and does not require cooling.

[0033] After the active stabilizer bar is activated, its real-time temperature is obtained, where the real-time temperature is the operating temperature of the active stabilizer bar.

[0034] For example, a temperature sensor is installed on the active stabilizer bar. The real-time temperature of the active stabilizer bar can be directly obtained through the temperature sensor, ensuring the real-time nature and accuracy of the real-time temperature data.

[0035] If the real-time temperature is greater than the target temperature threshold, it indicates that the active stabilizer bar needs to be cooled to ensure its stable operation. The opening degree of the electronic expansion valve should be set to the target opening value so that the cooling circuit can cool the active stabilizer bar.

[0036] For example, setting the opening degree of the electronic expansion valve to a target opening degree value ensures that there is a sufficient flow of coolant in the cooling circuit, which can guarantee the cooling effect of the active stabilizer bar.

[0037] The vehicle control method in this embodiment determines the target temperature threshold of the active stabilizer bar and the target opening value of the electronic expansion valve based on the vehicle's driving mode. Then, it compares the real-time temperature of the active stabilizer bar with the target temperature threshold to determine the timing for opening the cooling circuit. When the real-time temperature is greater than the target temperature threshold, the opening of the electronic expansion valve is set to the target opening value so that the cooling circuit cools the active stabilizer bar, ensuring that the active stabilizer bar operates under suitable temperature conditions. This improves the operational reliability of the active stabilizer bar and extends its service life.

[0038] In some embodiments, this application provides a vehicle control method that determines a target temperature threshold for an active stabilizer bar and a target opening value for an electronic expansion valve based on a driving mode, including: When the driving mode is comfort mode, obtain the first temperature threshold and the first opening value corresponding to comfort mode; Set the target temperature threshold to the first temperature threshold and the target opening value to the first opening value.

[0039] In this embodiment, when the driving mode is comfort mode, a first temperature threshold and a first opening value corresponding to comfort mode are obtained, wherein the first temperature threshold is the temperature threshold corresponding to comfort mode, and the first opening value is the opening value corresponding to comfort mode.

[0040] For example, the first temperature threshold may be specifically 120 degrees Celsius.

[0041] For example, the first opening value can be specifically 70%.

[0042] Set the target temperature threshold to the first temperature threshold and the target opening value to the first opening value.

[0043] For example, the first temperature threshold and the first opening value can meet the vehicle requirements of comfort mode.

[0044] In some embodiments, this application provides a vehicle control method that determines a target temperature threshold for an active stabilizer bar and a target opening value for an electronic expansion valve, including: When the driving mode is Sport mode, obtain the second temperature threshold and the second opening value corresponding to Comfort mode; Set the target temperature threshold to the second temperature threshold, and set the target opening value to the second opening value; The second temperature threshold is less than the first temperature threshold, and the second opening value is less than the first opening value.

[0045] In this embodiment, when the driving mode is Sport mode, a second temperature threshold and a second opening value corresponding to Comfort mode are obtained, wherein the second temperature threshold is the temperature threshold corresponding to Sport mode, and the second opening value is the opening value corresponding to Sport mode.

[0046] The second temperature threshold is less than the first temperature threshold, and the second opening value is less than the first opening value.

[0047] For example, the second temperature threshold may be specifically 100 degrees Celsius.

[0048] For example, the second opening value can be specifically 50%.

[0049] Set the target temperature threshold to the second temperature threshold, and set the target opening value to the second opening value.

[0050] For example, the second temperature threshold and the second opening value can meet the vehicle requirements in sport mode.

[0051] In some embodiments, this application provides a vehicle control method that determines a target temperature threshold for an active stabilizer bar and a target opening value for an electronic expansion valve based on a driving mode, including: When the driving mode is off-road mode, obtain the third temperature threshold and third opening value corresponding to the comfort mode; Set the target temperature threshold to the third temperature threshold, and set the target opening value to the third opening value; The third temperature threshold is less than the second temperature threshold, and the third opening value is less than the second opening value.

[0052] In this embodiment, when the driving mode is off-road mode, the third temperature threshold and the third opening value corresponding to the comfort mode are obtained, wherein the third temperature threshold is the temperature threshold corresponding to the off-road mode, and the third opening value is the opening value corresponding to the off-road mode.

[0053] The third temperature threshold is less than the second temperature threshold, and the third opening value is less than the second opening value.

[0054] For example, the second temperature threshold may be specifically 80 degrees Celsius.

[0055] For example, the second opening value can be specifically 30%.

[0056] Set the target temperature threshold to the third temperature threshold and the target opening value to the third opening value.

[0057] For example, the third temperature threshold and the third opening value can meet the vehicle requirements in off-road mode.

[0058] In some embodiments of this application, a vehicle control method is provided, which, after setting the opening degree of the electronic expansion valve to a target opening degree value, further includes: When the real-time temperature is below the target temperature threshold, the electronic expansion valve is closed to stop the cooling circuit.

[0059] In this embodiment, the real-time temperature of the active stabilizer is reacquired during the cooling process of the cooling circuit cooling the active stabilizer.

[0060] If the real-time temperature is lower than the target temperature threshold, it indicates that the active stabilizer bar does not require cooling. Therefore, the electronic expansion valve is closed to stop the cooling circuit.

[0061] In some embodiments, such as Figure 2 As shown, an embodiment of this application provides a vehicle control device 200, including: The first acquisition unit 202 is used to acquire the driving mode of the vehicle during the driving process. The determining unit 204 is used to determine the target temperature threshold of the active stabilizer bar and the target opening value of the electronic expansion valve according to the driving mode. The second acquisition unit 206 is used to acquire the real-time temperature of the active stabilizer bar after the active stabilizer bar has been activated. The control unit 208 is used to set the opening degree of the electronic expansion valve to a target opening degree value when the real-time temperature is greater than the target temperature threshold, so that the cooling circuit cools the active stabilizer bar.

[0062] In this embodiment, a vehicle control device 200 is proposed, wherein the vehicle includes an active stabilizer bar and an air conditioning system, the air conditioning system includes a cooling circuit for cooling the active stabilizer bar, and an electronic expansion valve is provided on the cooling circuit.

[0087] In some embodiments, such as Figure 3 As shown, a vehicle control device 300 is proposed. The vehicle control device 300 includes a processor 302 and a memory 304. The memory 304 stores a computer program, which, when executed by the processor 302, implements the steps of the vehicle control method as described in any of the above embodiments. Therefore, the vehicle control device 300 possesses all the beneficial effects of the vehicle control method in any of the above embodiments, which will not be elaborated further here.

[0088] In some embodiments, a readable storage medium is provided having a program stored thereon, which, when executed by a processor, implements the steps of the vehicle control method as described in any of the above embodiments, and thus has all the beneficial technical effects of the vehicle control method described in any of the above embodiments.

[0089] In some embodiments, a vehicle is provided, the vehicle comprising: Active stabilizer bar; A control system, which is used to execute the steps of the vehicle control method in any of the above embodiments; The air conditioning system includes a cooling circuit, which is used to cool the active stabilizer bar.

[0090] In some embodiments, a vehicle is provided, and the control system includes: a temperature sensor, a vehicle controller, and a first actuator, wherein the temperature sensor is connected to the vehicle controller and the first actuator is connected to the vehicle controller. An electronic expansion valve and a cooling jacket are installed on the cooling circuit, and the first actuator is connected to the electronic expansion valve; The active stabilizer bar includes a second actuator, and the cooling sleeve contacts the second actuator.

[0092] For example, such as Figure 4 As shown, the air conditioning system includes a compressor, a condenser, and a liquid receiver-drier.

[0093] For example, such as Figure 5 As shown, the second actuator of the active stabilizer bar is located in the middle of the active stabilizer bar, and the second actuator is connected to the left stabilizer bar and the right stabilizer bar respectively.

[0094] For example, the cooling jacket contacts the housing of the second actuator.
