Within this system, the integrated valve pump module serves as the core air supply unit, and its continuous and reliable operation is crucial.

[0003] In practical applications, especially under harsh conditions such as continuous suspension adjustment or high-temperature environments, significant heat accumulation occurs in the motor and adjacent valve body air passages within the integrated valve pump module. Excessive temperature can directly lead to motor performance degradation, aging of sealing materials, shortened component lifespan, and even permanent damage, seriously threatening system safety. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a control method and device for an air suspension system. By integrating multi-source temperature monitoring data, dynamically adjusting temperature constraints in conjunction with the operating authorization status of the air compression unit, and introducing multi-dimensional judgment control based on the working percentage, intelligent adaptive control of the air suspension system is achieved. This effectively avoids functional interruption while ensuring component safety, thereby improving system stability and user experience.

[0005] This application provides a control method for an air suspension system, the control method comprising: Acquire the first temperature monitoring data of the integrated valve pump module in the air suspension system, the second temperature monitoring data of the valve body air passage, and the operating status parameters of the air compression unit; Based on the operating authorization status in the operating status parameters of the air compression unit, obtain the first temperature constraint condition parameter currently corresponding to the integrated valve pump module and the second temperature constraint condition parameter currently corresponding to the valve body air passage. Based on at least one of the following: the first comparison result between the first temperature monitoring data and the first temperature constraint parameter, the second comparison result between the second temperature monitoring data and the second temperature constraint parameter, and the working percentage of the air compression unit in the operating status parameters, the operating authorization status of the air compression unit is controlled accordingly.

[0006] This application embodiment also provides a control device for an air suspension system, the control device comprising: The first acquisition module is used to acquire the first temperature monitoring data of the integrated valve pump module in the air suspension system, the second temperature monitoring data of the valve body air passage, and the operating status parameters of the air compression unit. The second acquisition module is used to acquire the first temperature constraint condition parameter currently corresponding to the integrated valve pump module and the second temperature constraint condition parameter currently corresponding to the valve body air passage based on the operating authorization status in the operating status parameters of the air compression unit. The control module is used to control the operating authorization status of the air compressor unit according to at least one of the following: a first comparison result between the first temperature monitoring data and the first temperature constraint parameter, a second comparison result between the second temperature monitoring data and the second temperature constraint parameter, and the working proportion of the air compressor unit in the operating status parameters.

[0007] This application also provides an electronic device, including: a processor, a memory, and a bus. The memory stores machine-readable instructions executable by the processor. When the electronic device is running, the processor communicates with the memory via the bus. When the machine-readable instructions are executed by the processor, the steps of the control method described above are performed.

[0008] This application also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, performs the steps of the control method described above.

[0009] This application provides a control method and apparatus for an air suspension system. The method includes: acquiring first temperature monitoring data of an integrated valve-pump module, second temperature monitoring data of the valve body air passage, and operating status parameters of an air compression unit in the air suspension system; acquiring first temperature constraint parameters currently corresponding to the integrated valve-pump module and second temperature constraint parameters currently corresponding to the valve body air passage based on the operating authorization status in the operating status parameters of the air compression unit; and controlling the operating authorization status of the air compression unit accordingly based on at least one of the following: a first comparison result between the first temperature monitoring data and the first temperature constraint parameters, a second comparison result between the second temperature monitoring data and the second temperature constraint parameters, and the working percentage of the air compression unit in the operating status parameters.

Furthermore, this solution simultaneously acquires the first temperature monitoring data of the integrated valve pump module in the air suspension system, the second temperature monitoring data of the valve body air passage, and the operating status parameters of the air compression unit. By comparing and making decisions based on these three data, it can more accurately assess the comprehensive impact of multiple factors such as heat dissipation conditions and load conditions on temperature rise. This significantly improves the adaptability and accuracy of the protection logic, enabling it to distinguish the actual overheating risk under different operating conditions and thus make more reasonable and efficient control decisions.

[0011] In summary, this solution provides an intelligent, proactive, and adaptive thermal management system through dynamic temperature constraints, proactive regulation based on workload ratio, and fusion decision-making using multi-source monitoring data. It not only provides effective protection when overheating occurs but also intervenes in advance to prevent overheating. Thus, while ensuring the long-term safe and reliable operation of the core components of the air suspension system, it maximizes the availability, continuity, and stability of the suspension function, fundamentally improving the overall performance of the product and the user experience.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.

[0016] First, the applicable scenarios for this application will be introduced. This application can be applied to the field of automotive technology.

[0017] Research has shown that the air suspension system, as a key component for improving vehicle ride comfort and handling, achieves suspension height and stiffness adjustment through the coordinated operation of air springs and the air supply system. Within this system, the integrated valve pump module serves as the core air supply unit, and its continuous and reliable operation is crucial.

[0018] In practical applications, especially under harsh conditions such as continuous suspension adjustment or high-temperature environments, significant heat accumulation occurs in the motor and adjacent valve body air passages within the integrated valve pump module. Excessive temperature can directly lead to motor performance degradation, aging of sealing materials, shortened component lifespan, and even permanent damage, seriously threatening system safety.

[0019] Based on this, embodiments of this application provide a control method and apparatus for an air suspension system, which can realize intelligent adaptive control of the air suspension system, thereby ensuring the safety of components while effectively avoiding functional interruption, and thus improving system stability and user experience.

[0020] Please see Figure 1 , Figure 1 This is a flowchart illustrating a control method for an air suspension system provided in an embodiment of this application. Figure 1 As shown in the embodiments of this application, the control method includes: S101. Obtain the first temperature monitoring data of the integrated valve pump module in the air suspension system, the second temperature monitoring data of the valve body air passage, and the operating status parameters of the air compression unit.

[0021] S102. Based on the operating authorization status in the operating status parameters of the air compression unit, obtain the first temperature constraint condition parameter currently corresponding to the integrated valve pump module and the second temperature constraint condition parameter currently corresponding to the valve body air passage.

[0022] S103. Based on at least one of the following: the first comparison result between the first temperature monitoring data and the first temperature constraint parameter, the first comparison result between the second temperature monitoring data and the second temperature constraint parameter, and the working percentage of the air compression unit in the operating status parameters, the operating authorization status of the air compression unit is controlled accordingly.

[0023] The exemplary steps of the embodiments of this application are described below: For step S101, this step may include: acquiring the first temperature monitoring data of the integrated valve pump module in the air suspension system according to the preset monitoring rules, acquiring the second temperature monitoring data of the valve body air passage in the air suspension system, and acquiring the operating status parameters of the air compression unit in the air suspension system.

[0024] Here, the preset monitoring rules can be used for real-time monitoring or periodic monitoring. For example, this solution can be set to use a temperature protection algorithm that monitors the air suspension system in real time with a 10ms task cycle to ensure timely response.

[0025] Specifically, the integrated valve-pump module can be a closed-loop valve-pump module. The first temperature monitoring data of the integrated valve-pump module includes a first operating temperature and the cumulative duration during which the first operating temperature exceeds a corresponding temperature threshold. The second temperature monitoring data at the valve body air passage includes a second operating temperature and the cumulative duration during which the second operating temperature exceeds a corresponding temperature threshold.

[0026] Furthermore, in one embodiment provided in this application, the first operating temperature of the integrated valve pump module is determined by the following steps: obtaining the operating temperatures at multiple locations on the control unit of the integrated valve pump module; and determining the highest temperature among the multiple operating temperatures as the first operating temperature of the integrated valve pump module.

[0027] For example, the multiple locations on the integrated valve pump module control unit can specifically be multiple key locations on the PCB board on which the control chip is installed, and the multiple locations can specifically be three locations.

[0028] It should be noted that the integrated valve pump module consists of a control unit, an actuator, and a compressor in sequence. Existing solutions use sensors in the actuator to detect the air duct temperature, roughly estimating whether the compressor temperature is too high and determining whether to stop the compressor. However, due to the time lag in heat transfer through the air duct, the compressor might reach over 150 degrees Celsius while the air duct temperature is only 70-80 degrees Celsius, making it impossible to stop the motor in time. This solution utilizes three temperature sensors on the control unit, which are highly sensitive to temperature. Therefore, multiple cycles are set for repeated counting and judgment to ensure timely response.

[0029] Continuing with step S101, the air compression unit may specifically be an air compressor, and the operating status parameters of the air compression unit may include the operating authorization status of the air compression unit and the percentage of work performed by the air compression unit within a predetermined time period.

[0030] Regarding step S102, the operating authorization status in the operating status parameters of the air compression unit includes "allowed to work" and "prohibited to work". In this step, different operating authorization statuses of the air compression unit result in different first temperature constraint parameters for the integrated valve-pump module and different second temperature constraint parameters for the valve body air passage.

[0031] For example, in one embodiment provided in this application, obtaining the first temperature constraint parameter currently corresponding to the integrated valve pump module and the second temperature constraint parameter currently corresponding to the valve body air passage based on the operating authorization status in the operating status parameters of the air compression unit includes: When the operation authorization status in the operation status parameters is "allowed to work", the first temperature constraint condition parameter includes a first temperature threshold and a first duration threshold, and the second temperature constraint condition parameter includes a second temperature threshold and a second duration threshold; wherein, the first temperature threshold is not less than the second temperature threshold, and the second duration threshold is not less than the first duration threshold; When the operation authorization status in the operation status parameters is prohibited from working, the first temperature constraint condition parameter includes a third temperature threshold and a third duration threshold, and the second temperature constraint condition parameter includes a fourth temperature threshold and a fourth duration threshold; wherein, the third temperature threshold is not less than the fourth temperature threshold, and the fourth duration threshold is not less than the third duration threshold.

[0032] Here, the specific value of the first duration threshold can be determined based on the upper limit of the safe temperature of the circuit board in the integrated valve-pump module. The first duration threshold is lower than the upper limit of the safe temperature.

[0033] Furthermore, in another embodiment provided in this application, the first temperature threshold is greater than the third temperature threshold, the second temperature threshold is greater than the fourth temperature threshold, the third duration threshold is greater than the first duration threshold, and the fourth duration threshold is greater than the second duration threshold.

[0034] For step S103, this step specifically includes: comparing the first temperature monitoring data with the first temperature constraint parameters to obtain a first comparison result; comparing the second temperature monitoring data with the second temperature constraint parameters to obtain a second comparison result; and comparing the working proportion of the air compression unit in the operating status parameters with the corresponding proportion threshold to obtain a third comparison result. Based on at least one of the first comparison result, the second comparison result, and the third comparison result, the current operating state that the air compression unit should perform is determined, and corresponding control is performed.

[0035] Furthermore, regarding step S103, in one embodiment provided in this application, when the operating authorization status in the operating status parameters is "allowed to work," the step of controlling the operating authorization status of the air compressor unit according to at least one of the following: a first comparison result between the first temperature monitoring data and the first temperature constraint parameter, a first comparison result between the second temperature monitoring data and the second temperature constraint parameter, and the operating percentage of the air compressor unit determined by the operating status parameters; includes: S10311. Based on the first temperature monitoring data, determine whether the cumulative duration for which the first operating temperature of the integrated valve pump module exceeds the first temperature threshold exceeds the first duration threshold.

[0036] S10312. Based on the second temperature monitoring data, determine whether the cumulative duration for which the second working temperature at the valve body air passage exceeds the second temperature threshold exceeds the second duration threshold.

[0037] S10313. Determine whether the working percentage of the air compression unit exceeds the percentage threshold based on the operating status parameters. S10314. If any of the above three conditions are met, the operating authorization state of the air compression unit shall be set to prohibited operation. S10315. If none of the above three conditions are met, maintain the operating authorization status of the air compression unit as allowed to operate.

[0038] Regarding steps S10311-S10312, in one embodiment provided in this application, the cumulative duration of the integrated valve pump module exceeding a first temperature threshold and the cumulative duration of the valve body air passage exceeding a second temperature threshold are determined through the following steps: S201. When the monitoring time point is reached, acquire the current temperature monitoring data at the target location in the air suspension system; the target location is the integrated valve pump module and the valve body air passage; the current temperature monitoring data includes first temperature monitoring data and second temperature monitoring data; the first temperature monitoring data includes a first operating temperature and the current cumulative duration exceeding the first temperature threshold up to the current monitoring time point; the second temperature monitoring data includes a second operating temperature and the current cumulative duration exceeding the second temperature threshold up to the current monitoring time point. S202. Identify whether the current monitored temperature in the current temperature monitoring data exceeds the target temperature threshold; wherein, the current monitored temperature includes a first operating temperature and a second operating temperature, and the target temperature threshold includes a first temperature threshold and a second temperature threshold; S203. If the time limit is exceeded, the current cumulative time corresponding to the current monitored temperature will be increased by the first time. S204. If it does not exceed the limit, reduce the current cumulative duration corresponding to the current monitored temperature by a second duration; wherein the second duration is not less than the first duration.

[0039] For step S204, the second duration is generally set to be greater than the first duration.

[0040] If the cumulative duration corresponding to the current monitored temperature is reduced by a second duration and the cumulative duration becomes negative, then the cumulative duration is set to 0.

[0041] Specifically, step S10313 may include: determining the percentage of operation of the air compression unit within a preset time period based on the operating status parameters, and determining whether the percentage of operation exceeds a percentage threshold.

[0042] For example, it can be set to determine whether the cumulative working time of the air compression unit in the last 10 minutes is greater than the percentage threshold of 50%.

[0043] Furthermore, in another embodiment provided in this application, when the operating authorization status in the operating status parameters is prohibited from operation, the step of controlling the operating authorization status of the air compressor unit according to at least one of the following: a first comparison result between the first temperature monitoring data and the first temperature constraint parameter, a first comparison result between the second temperature monitoring data and the second temperature constraint parameter, and the operating percentage of the air compressor unit determined by the operating status parameters, includes: S10321. Based on the first temperature monitoring data, determine whether the cumulative duration for which the first operating temperature of the integrated valve pump module is lower than the third temperature threshold exceeds the third duration threshold. S10322. Based on the second temperature monitoring data, determine whether the cumulative duration for which the second working temperature at the valve body air passage is lower than the fourth temperature threshold exceeds the fourth duration threshold. S10323. Determine whether the working percentage of the air compression unit does not exceed the percentage threshold based on the operating status parameters. S10324. If all three of the above are true, control the operation authorization status of the air compression unit to allow operation; S10325. If any of the above three conditions are not met, the operating authorization status of the air compression unit shall be maintained as prohibited from operation.

[0044] Furthermore, in another embodiment provided in this application, the cumulative duration of the integrated valve pump module exceeding the third operating temperature threshold and the cumulative duration of the valve body air passage exceeding the fourth operating temperature threshold are determined by the following steps: S201. When the monitoring time point is reached, acquire the current temperature monitoring data at the target location in the air suspension system; the target location is the integrated valve pump module and the valve body air passage; the current temperature monitoring data includes third temperature monitoring data and fourth temperature monitoring data; the third temperature monitoring data includes the third operating temperature and the current cumulative duration exceeding the third temperature threshold up to the current monitoring time point; the fourth temperature monitoring data includes the fourth operating temperature and the current cumulative duration exceeding the fourth temperature threshold up to the current monitoring time point. S202. Identify whether the current monitored temperature in the current temperature monitoring data exceeds the target temperature threshold; wherein, the current monitored temperature includes a third operating temperature and a fourth operating temperature, and the target temperature threshold includes a third temperature threshold and a fourth temperature threshold; S203. If the time limit is exceeded, the current cumulative time corresponding to the current monitored temperature will be increased by a third time. S204. If it does not exceed the limit, reduce the current cumulative duration corresponding to the current monitored temperature by a fourth duration; wherein the fourth duration is not less than the third duration.

[0045] Here, the third duration can be set to be equal to the first duration, and the fourth duration can be set to be equal to the second duration.

[0046] If the cumulative duration corresponding to the current monitored temperature is reduced by the fourth duration and the cumulative duration becomes negative, then the cumulative duration is set to 0.

[0047] Based on the same inventive concept, this application also provides a control device corresponding to the control method. Since the principle of the device in this application is similar to the control method described above, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.
