DETAILED DESCRIPTION

[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0056] Before introducing the embodiments of the present application, the application background of the embodiments of the present application is first explained:

[0057] With the rapid development of intelligence and electrification in the automotive industry, active suspension systems are becoming more mature, especially air suspension systems, which are increasingly being used in various types of vehicles.

[0058] The air suspension system may overheat when working frequently. In the current prior art, the air suspension system adopts a passive method to deal with the overheating problem, that is, the air suspension system stops running when the temperature reaches the temperature threshold of the system.

[0059] The problem of the prior art to be solved by the embodiment of the present application is that when the temperature reaches the temperature threshold of the system, there is already a negative impact on the service life of the air suspension system, and directly stopping the operation of the air suspension system will cause the vehicle to be bumpy during operation, affecting the user's experience.

[0060] In response to the technical problems existing in the prior art, the inventor of the present application has conceived that in order to avoid overheating of the air suspension system, the current temperature of the vehicle can be collected in real time during the operation of the vehicle, and the temperature threshold corresponding to the overheating of the air suspension system can be obtained. In order to avoid the passive implementation of stopping operation after the current temperature reaches the temperature threshold of the air suspension system, the output power of the air compressor can be adjusted in time to be lower than the standard power when the current temperature is close to the temperature threshold. In order to avoid the performance of the air suspension system, the pressure threshold of the air tank in the air suspension system is adjusted to be lowered, thereby reducing the heat caused by excessive power and avoiding the impact on the air suspension system, so as to achieve cooling of the air suspension system and take into account the driving experience of the user.

[0061] In addition, the user is informed of this situation through the human-machine interaction interface and / or the audio unit on the vehicle to increase user perception.

[0062] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0063] Figure 1 The schematic diagram of the air suspension system structure provided in the embodiment of the present application is as follows: Figure 1 As shown, the air suspension system structure diagram includes: front shock absorber and air spring assembly, suspension height sensor, rear shock absorber, suspension system controller, air tank, pipeline, air compressor, and rear air spring.

[0064] Among them, overheating of the air suspension system is actually overheating of the air compressor.

[0065] exist Figure 1 Based on the structure shown, Figure 2 The working sequence diagram of the air suspension system provided in the embodiment of the present application is as follows: Figure 2 As shown, including:

[0066] 1) The air spring provides real-time feedback of the current height information;

[0067] 2) The air compressor feeds back the current temperature, and the suspension controller determines whether the current temperature of the air compressor reaches a first temperature threshold;

[0068] 3) The air tank feeds back the current pressure value, and the suspension controller determines whether the pressure value reaches the pressure threshold;

[0069] 4) After the suspension controller determines that there is a work demand, it sends a work request to the air compressor;

[0070] 5) The air compressor starts working to fill the air tank;

[0071] 6) The air tank inflates the air spring chamber.

[0072] The above-mentioned undisclosed matters are explained in detail by the following embodiments. The executor of the embodiments of the present application is a vehicle, specifically a suspension controller in an air suspension system in the vehicle.

[0073] Figure 3 Schematic diagram of the control method of the air suspension system provided in the embodiment of the present application Figure 1 ,like Figure 3 As shown, the control method of the air suspension system includes:

[0074] Step 31, obtaining the current temperature of the air compressor in the air suspension system in real time;

[0075] In this step, the temperature of the air suspension system is overheated, which indicates that the temperature of the air compressor in the air suspension system is overheated. Therefore, it is necessary to collect the current temperature of the air compressor in real time.

[0076] It should be understood that in the embodiment of the present application, the current temperature is collected in real time based on the process of the control method and is a changing value.

[0077] Step 32: When it is detected that the current temperature is greater than the first temperature threshold, the output power of the air compressor is adjusted to the first power value, and the pressure threshold of the air tank in the air suspension system is adjusted to the first pressure value;

[0078] Among them, the first temperature threshold is determined based on the temperature threshold of the air compressor and the first preset coefficient, the first power value is determined based on the standard power of the air compressor and the second preset coefficient, the first pressure value is determined based on the standard pressure of the air tank and the third preset coefficient, and the first preset coefficient, the second preset coefficient, and the third preset coefficient are all coefficients less than 1 and greater than 0.

[0079] In this step, the temperature thresholds set for different types of air compressors (such as piston type, screw type, centrifugal type, etc.) and different application scenarios (such as industry, household, automobile, etc.) may be different, that is, the setting of the temperature threshold is based on the actual structure and application scenario. In this embodiment, the temperature threshold is adjusted using a first preset coefficient to obtain a first temperature threshold that is lower than the temperature threshold. When it is detected that the current temperature is greater than the first temperature threshold, the output power of the air compressor is adjusted immediately to achieve the purpose of active cooling without endangering the air suspension system.

[0080] Furthermore, generally speaking, the higher the power, the higher the temperature of the air compressor. At this time, the output power of the air compressor can be reduced to a first power value, that is, the standard power of the air compressor is adjusted using the second preset coefficient to obtain the first power value.

[0081] In addition, in order not to affect the user's car-using experience, on the basis of adjusting the power, the pressure threshold of the air tank in the air suspension system is adjusted to a first pressure value, so that when the air suspension system is working, it is easier to trigger the air tank to inflate the air spring, that is, the standard pressure of the air tank is adjusted using the third preset coefficient to obtain the first pressure value.

[0082] Optionally, the first preset coefficient can be 70%, then the first temperature threshold = the temperature threshold of the air compressor * 70%; the second preset coefficient can be 50%, then the first power value = the standard power of the air compressor * 50%; the third preset coefficient can be 60%, then the first pressure value = the standard pressure of the air tank * 60%.

[0083] Further, the first information is displayed through the human-computer interaction interface, or / and played through the audio unit, and the first information is used to prompt the user that the air suspension system is in a cooling stage.

[0084] In this implementation, since the air suspension system enters a specific cooling implementation, the vehicle hardware can be used to inform the user so that the user can perceive that the air suspension system is in the cooling stage and the system performance is temporarily reduced. There are two specific implementations:

[0085] First, the first information is displayed through a human-machine interface, such as a human-machine interface (HMI); second, the first information is played through an audio unit on the vehicle.

[0086] Optionally, after step 31 , the following may be performed: when it is detected that the current temperature is less than or equal to the first temperature threshold, the air storage tank is inflated by an air compressor so that the air storage tank inflates the air spring chamber in the air suspension system.

[0087] In this implementation, when it is detected in real time that the current temperature is not greater than the first temperature threshold of active cooling set above, the air compressor is controlled to inflate the air tank so that the air tank has sufficient gas, so that the air tank can inflate the air spring chamber in the air suspension system to realize the operation of the air suspension system.

[0088] Further, it can also be implemented as follows: when it is detected that the current temperature is less than the second temperature threshold, the output power of the air compressor is adjusted to the standard power, and the pressure threshold of the air tank in the air suspension system is adjusted to the standard pressure;

[0089] The second temperature threshold is determined based on the temperature threshold of the air compressor and a fourth preset coefficient, the fourth preset coefficient is smaller than the first preset coefficient, and the fourth preset coefficient is a coefficient less than 1 and greater than 0.

[0090] In this implementation, that is, after the active cooling measures are implemented, the current temperature is detected in real time, and a judgment is made based on the second temperature threshold. There is no need to continue to implement cooling measures, that is, to restore the output power of the air compressor to the standard power, and to restore the pressure threshold of the air tank in the air suspension system to the standard pressure.

[0091] Optionally, the fourth preset coefficient is smaller than the first preset coefficient, and may be 50%, that is, the second temperature threshold=the temperature threshold of the air compressor*50%.

[0092] The control method of the air suspension system provided in the embodiment of the present application obtains the current temperature of the air compressor in the air suspension system in real time; when it is detected that the current temperature is greater than the first temperature threshold, the output power of the air compressor is adjusted to the first power value, and the pressure threshold of the air tank in the air suspension system is adjusted to the first pressure value; wherein the first temperature threshold is determined based on the temperature threshold of the air compressor and the first preset coefficient, the first power value is determined based on the standard power of the air compressor and the second preset coefficient, and the first pressure value is determined based on the standard pressure of the air tank and the third preset coefficient, and the first preset coefficient, the second preset coefficient, and the third preset coefficient are all coefficients less than 1 and greater than 0. In this technical solution, by detecting the current temperature of the air compressor, when it is greater than the temperature threshold corresponding to the overheating of the air compressor and the first temperature threshold determined by the first preset coefficient, active intervention is performed to adjust the output power of the air compressor to reduce it, thereby reducing the heating phenomenon caused by excessive power, and adjusting the pressure threshold of the air tank in the air suspension system to reduce it, avoiding the impact on the air suspension system, so as to achieve the cooling of the air suspension system and take into account the driving experience of the user.

[0093] Based on the above embodiments, Figure 4 Schematic diagram of the control method of the air suspension system provided in the embodiment of the present application Figure 2 ,like Figure 4 As shown, the implementation of step 31 may be:

[0094] Step 41, obtaining status information of the air suspension system;

[0095] In this step, after the air suspension system is powered on, it is necessary to first obtain whether there is a work demand during the operation of the vehicle, that is, to obtain the status information of the air suspension system.

[0096] Among them, the status information is used to indicate whether there is a need to adjust the hardness and height of the suspension.

[0097] Step 42: when it is detected that the status information indicates that there is a work demand, obtain a second pressure value of the gas storage tank;

[0098] In this step, when it is detected that the status information indicates that there is a work demand, it is necessary to first obtain the pressure value of the gas storage tank, which is recorded as the second pressure value.

[0099] This is because when the second pressure value of the air tank meets the subsequent working requirements, there is no need for the operation of the air compressor in the air suspension system, and there is no need to take active cooling measures for the air compressor; when the second pressure value of the air tank does not meet the subsequent working requirements, the air compressor needs to be operated to inflate the air tank, that is, the temperature of the air compressor is too high.

[0100] Optionally, the operating demand is determined by a suspension controller in the air suspension system.

[0101] Step 43: When it is detected that the second pressure value does not meet the working requirement, the current temperature of the air compressor is obtained.

[0102] In this step, when it is detected that the second pressure value does not meet the working requirement, the temperature rises due to the operation of the air compressor, and the current temperature of the air compressor is obtained in real time.

[0103] In addition, when it is detected that the second pressure value meets the working requirement, the air spring chamber in the air suspension system is inflated through the air storage tank.

[0104] In this implementation, when the second pressure value meets the working requirements, the gas in the gas tank is input into the air spring chamber, so that the air spring realizes the operation of the air suspension system, so that the vehicle runs smoothly.

[0105] The control method of the air suspension system provided in the embodiment of the present application obtains the status information of the air suspension system, and when it is detected that the status information indicates that there is a work demand, obtains the second pressure value of the air storage tank, and when it is detected that the second pressure value does not meet the work demand, obtains the current temperature of the air compressor. In this technical solution, when it is detected that the air suspension system has a work demand, and the pressure value is insufficient to start the air compressor, the current temperature of the air compressor is obtained at this time to accurately specify the timing of obtaining the current temperature and avoid redundant operations.

[0106] Based on the above embodiments, Figure 5 Schematic diagram of the control method of the air suspension system provided in the embodiment of the present application Figure 3 ,like Figure 5 As shown, an example implementation may be:

[0107] Step 1: Power on the air suspension system;

[0108] Step 2: Determine whether the air suspension system needs to work; if so, proceed to step 3; if not, continue to determine;

[0109] Step 3: Determine whether the pressure of the gas storage tank (the second pressure value) meets the working requirements; if not, execute step 4; if yes, execute step 8;

[0110] Step 4: determine whether the temperature of the air compressor is greater than the first temperature threshold; if so, execute step 5; if not, execute step 7;

[0111] Step 5: Enter active cooling operation (related operation of step 32 above);

[0112] Step 6: Determine whether to execute active cooling exit. If yes, execute step 2; if no, execute step 5;

[0113] Step 7: Inflate with air compressor;

[0114] Step 8: Inflate the air spring;

[0115] Step 9. Power off the air suspension system.
