Description

Technical Field

[0001] This invention relates to the field of air spring adjustment in vehicles, and more particularly to a method, apparatus, device, and storage medium for monitoring and adjusting air springs. Background Technology

[0002] An air spring system, short for air suspension system, is commonly used in vehicle suspension systems. Its principle is based on the increasing stiffness of the sealed gas within the air spring as it is compressed. As the air spring is continuously compressed, its stiffness gradually increases. Simultaneously, the internal gas is forced in or expelled as the air spring is compressed or stretched, resulting in near-ideal dynamic elastic characteristics for the air suspension system. The advantages of an air spring system include improved passenger comfort and protection against road damage. Furthermore, by adjusting the spring rate or air pressure of the air springs, the vehicle's height and suspension stiffness can be adjusted, improving handling and driving stability.

[0003] Existing air spring systems typically use sensors to monitor parameters such as vehicle height and air pressure for automatic adjustment. However, when a sensor malfunctions, the air spring system stops adjusting, causing parameters like vehicle height and air pressure to become unstable, affecting driving safety and comfort. In this situation, the user will attempt to adjust the air spring system to restore stability to these parameters. However, if sensor malfunction renders adjustment ineffective, the user will feel disappointed and confused because the air springs are unresponsive, thus degrading the user experience. Summary of the Invention

[0004] To address the problem of air spring system failure in the event of an abnormality in the height sensor in the prior art, this invention provides a method, apparatus, device, and storage medium for monitoring and adjusting air springs.

[0005] This invention provides a method for monitoring and adjusting an air spring, comprising:

[0006] The height of the vehicle's four wheels is detected in real time using height sensors to obtain the height value of each wheel;

[0007] Determine whether the corresponding height sensor is malfunctioning based on the height value;

[0008] If any abnormal height sensors are found, the air springs that need adjustment will be determined based on the number, location, and height values ​​of the abnormal height sensors; specifically:

[0009] If an abnormal height sensor exists, adjust the air spring corresponding to the abnormal height sensor;

[0010] If there are two abnormal height sensors, the following steps are performed according to the relative positions of the two abnormal height sensors:

[0011] When the two abnormal height sensors are diagonally opposite each other, the air spring is not adjusted.

[0012] When the two abnormal height sensors are coaxial, the decision on whether to adjust the air spring is based on whether the abnormal height sensors can output valid values.

[0013] When the two abnormal height sensors are on the same side, the air springs corresponding to the abnormal height sensors are adjusted simultaneously.

[0014] If three or four of the aforementioned abnormal height sensors are present, the air spring is not adjusted.

[0015] Furthermore, based on the stated height value, it is determined whether the corresponding height sensor is malfunctioning, specifically as follows:

[0016] If the height value falls under any of the following circumstances: the height value exceeds the preset height value range, the height value has no data, or the height value is garbled, then the height sensor corresponding to the height value is considered to be an abnormal height sensor; otherwise, it is considered to be a normal height sensor.

[0017] Furthermore, the preset height value range is D-20mm≤H≤D-20mm, where D refers to the current gear setting height value of the vehicle, and H is the currently measured height value.

[0018] Furthermore, the method for determining the valid value is as follows: if the abnormal height sensor can output a height value and it does not exceed the limit value that the vehicle chassis can adjust, then the abnormal height sensor is considered to output a valid value; if the abnormal height sensor can output a height value but the height value exceeds the limit value that the vehicle chassis can adjust, or the height value output by the abnormal height sensor has no data or the height value is garbled, then the abnormal height sensor is considered not to output a valid value.

[0019] Furthermore, if an abnormal height sensor exists, the air spring corresponding to the abnormal height sensor is adjusted, specifically as follows:

[0020] If the abnormal height sensor can output a valid value, then calculate the average value of the height value of the abnormal height sensor and the height value of the normal height sensor coaxial with the abnormal height sensor, and adjust the air spring corresponding to the abnormal height sensor according to the average value.

[0021] If the abnormal height sensor cannot output a valid value, the air spring corresponding to the abnormal height sensor is adjusted according to the height value of the normal height sensor coaxial with the abnormal height sensor.

[0022] Furthermore, when the two abnormal height sensors are coaxial, the adjustment of the air spring is determined based on whether the abnormal height sensors output valid values. Specifically:

[0023] If both abnormal height sensors can output valid values, the average height values ​​of the two abnormal height sensors are calculated, and the air springs corresponding to the two abnormal height sensors are adjusted according to the average value; otherwise, the air springs are not adjusted.

[0024] Furthermore, when the two abnormal height sensors are on the same side, the air springs corresponding to the abnormal height sensors are adjusted simultaneously, specifically as follows:

[0025] The following operations are performed on the two abnormal height sensors respectively: the air spring corresponding to the abnormal height sensor is adjusted according to the height value of the normal height sensor coaxial with the abnormal height sensor.

[0026] Furthermore, the method also includes the following operations after obtaining the air spring that needs to be adjusted: real-time detection of the temperature and pressure of the air tank, selection of the device for air pumping the air spring based on the temperature and pressure, and using the air tank to pump the air spring when the temperature and pressure of the air tank are within the normal working range, otherwise using a compressor to pump the air spring.

[0027] A monitoring and adjustment device for an air spring, using the monitoring and adjustment method for an air spring as described in any of the preceding claims, specifically includes the following modules:

[0028] The receiving module is used to detect the height of the four wheels of the vehicle in real time through the height sensor and obtain the height value of each wheel;

[0029] The judgment module, connected to the receiving module, is used to determine whether the corresponding height sensor is abnormal based on the height value. If there is an abnormal height sensor, the air spring that needs to be adjusted is determined based on the number, location and height value of the abnormal height sensor.

[0030] An adjustment module, connected to the judgment module, is used to adjust the air spring that needs to be adjusted.

[0031] A monitoring and adjustment device for an air spring, comprising:

[0032] A memory for storing a computer-executable program for the monitoring and adjustment method of the air spring as described in any of the preceding items;

[0033] A processor is configured to retrieve the computer execution program from the memory and execute the monitoring and adjustment method for the air spring.

[0034] Advantages and beneficial effects of the present invention:

[0035] 1. When the air spring system malfunctions due to a height sensor malfunction, this invention designs multiple air spring adjustment schemes and selects one according to the actual situation to adjust the air spring system, ensuring driving safety and comfort, and thus reducing the problem of poor customer experience caused by the air spring system not responding to adjustments.

[0036] 2. In the case of two abnormal height sensors, this invention determines the air spring that needs to be adjusted based on the number, location and height value of the abnormal height sensors, so as to achieve the adjustment of the air spring system more scientifically and further ensure driving safety.

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it.

[0044] As described in the background section, sensors play a crucial role in existing vehicle air spring systems, monitoring key parameters such as vehicle height and air pressure. Through real-time feedback from these sensors, the air spring system can automatically adjust to ensure vehicle stability and comfort under various driving conditions.

[0045] However, if any sensor malfunctions, the air spring system will lose its ability to monitor the corresponding parameters and cannot make effective adjustments. This will cause parameters such as vehicle height and air pressure to become unstable, negatively impacting vehicle safety and comfort.

[0046] In this situation, the user will attempt to adjust the air spring system to restore stability to parameters such as vehicle height and air pressure. However, if a sensor malfunction renders the adjustment ineffective, the user will not achieve the expected results. This ineffective adjustment will leave the user frustrated and confused, as the air spring system does not provide the expected response, thus degrading the user experience.

[0047] Furthermore, adopting effective response strategies and backup plans in the event of sensor malfunction is a crucial aspect of ensuring vehicle driving safety and comfort.

[0048] In view of the defects in the existing technology, the present invention provides a monitoring and adjustment method for the air spring. When the height sensor is abnormal, the air spring is selectively adjusted according to the actual situation, thereby reducing the situation where the air spring adjustment system does not respond, improving the customer experience, and ensuring driving safety and comfort.

[0049] The air spring system is an air suspension system for vehicles that adjusts vehicle height to improve comfort and handling. This invention addresses the scenario where a vehicle has one adjustable air spring at each of its four wheels; other numbers of air springs can be adaptively adjusted according to this invention.

[0050] like Figure 1 As shown, an air spring system typically consists of four height sensors, an air tank (not shown), an air spring (not shown), and an regulator (not shown).

[0051] The height sensor is an important component of the air spring system. It detects changes in the vehicle's height and transmits the signal to the adjuster. Based on the received signal, the adjuster controls the inflation and deflation of the air springs, thereby adjusting the vehicle's height.

[0052] The gas storage tank is used to store high-pressure gas, providing the necessary inflation and deflation support for the air spring.

[0053] Example 1

[0054] Please refer to Figure 2 As shown, a method for monitoring and adjusting an air spring includes the following steps:

[0055] S101. The height of the four wheels of the vehicle is detected in real time by a height sensor to obtain the height value of each wheel.

[0056] For air spring systems, in order to ensure their normal operation and safety, key parameters that need to be monitored include the height values ​​of the height sensors corresponding to the four wheels, the pressure of the air tank, and the temperature.

[0057] Specifically, the height sensors corresponding to the four wheels are used to monitor changes in the height of the vehicle's four wheels in real time. By obtaining feedback from these sensors, the vehicle's height information is acquired under different driving conditions, thereby determining the vehicle's attitude and stability. This is crucial for maintaining smooth vehicle operation and adjusting the air spring system.

[0058] The air reservoir is a key component of the air spring system, and its pressure changes reflect the system's operating status and inflation level. By monitoring the air reservoir pressure, it's possible to determine whether the air spring system is functioning correctly and whether adjustments to the inflation pressure are needed to maintain vehicle height stability.

[0059] Temperature has a significant impact on the performance and stability of components in an air spring system. Real-time temperature monitoring allows for the timely detection of excessively high or low temperatures, enabling appropriate measures to be taken to protect the air spring system and ensure its normal operation.

[0060] S102. Determine whether the corresponding height sensor is malfunctioning based on the height value.

[0061] The height sensor corresponding to the height value is considered to be an abnormal height sensor if any of the following conditions are met; otherwise, it is considered a normal height sensor:

[0062] The height value detected by the height sensor exceeds the preset height value range: the preset height value range is D-20mm≤H≤D-20mm, where D refers to the current gear setting height value of the vehicle, and H is the currently measured height value.

[0063] The height sensor is not returning data, meaning there is no height value detected.

[0064] The height sensor returned garbled values ​​that could not be recognized or parsed.

[0065] Specifically, it's necessary to determine whether the height value detected by the height sensor exceeds the height range corresponding to the vehicle's current gear. Each gear corresponds to a preset height range; if the sensor value exceeds this range, it indicates a malfunction in the height sensor.

[0066] If the altitude sensor does not return valid data, this is also an abnormal situation. This is due to sensor malfunction, wiring problems, or other reasons.

[0067] If the height sensor returns garbled values ​​that cannot be recognized or deciphered, it indicates a sensor malfunction. The preset height range refers to the vehicle's current gear setting height value ±20mm.

[0068] If the height sensor is working properly, determine whether the air spring needs adjustment based on the difference between the height value and the height value set for the current gear position of the vehicle.

[0069] Specifically, when the height reading is within the normal error range, i.e., within ±5mm of the vehicle's current gear setting height, the air spring does not need adjustment. However, when the height reading is between ±5mm and ±20mm of the vehicle's current gear setting height, it indicates that the current gear has not yet been reached, and the air spring needs further adjustment. If a certain gear has been reached (or is in a certain gear but has not been adjusted), and the sensor reading exceeds ±20mm of the vehicle's current gear setting height, then the height sensor reading is considered abnormal.

[0070] S103. If there are abnormal height sensors, determine the air spring that needs to be adjusted based on the number, location and height value of the abnormal height sensors.

[0071] Based on the number, location, and height value of the faulty height sensors, they can be categorized as follows:

[0072] 1. If an abnormal height sensor exists, adjust the air spring corresponding to the abnormal height sensor.

[0073] If the abnormal height sensor can output a valid value, then calculate the average value of the height value of the abnormal height sensor and the height value of the normal height sensor coaxial with the abnormal height sensor, and adjust the air spring corresponding to the abnormal height sensor according to the average value.

[0074] If the abnormal height sensor cannot output a valid value, the air spring corresponding to the abnormal height sensor is adjusted according to the height value of the normal height sensor coaxial with the abnormal height sensor.

[0075] Figure 3 This is a schematic diagram of an abnormal height sensor adjustment strategy in this invention. When the left front height sensor is abnormal, it is determined whether the height sensor has a valid value. If it is a valid value, the height value of the left front height sensor and the average value of the height value of the right front height sensor are calculated first, and then the left front air spring is adjusted according to the average value. If it is invalid data, the left front air spring is adjusted according to the height value of the right front height sensor.

[0076] 2. If there are two abnormal height sensors, there will be three possible scenarios depending on the relative positions of the two abnormal height sensors.

[0077] The two abnormal height sensors are diagonally opposite each other, coaxially aligned, and on the same side.

[0078] When the two height sensors are diagonally opposite each other, adjustment of the air spring system is prohibited. The reason is that a vehicle axle (e.g., a wheel axle) and its corresponding wheel form a plane. The existence of this plane ensures the stability and safety of the vehicle. Under normal circumstances, the readings of the diagonal height sensors should reflect the existence of this plane; that is, the height values ​​detected by the diagonal height sensors should be consistent. If the readings of the diagonal height sensors are abnormal, it means that this plane has been disrupted, and adjustment of the air spring system should be prohibited to avoid adverse effects on vehicle operation.

[0079] When the two abnormal height sensors are coaxial, the adjustment of the air spring is determined based on whether the abnormal height sensors can output valid values.

[0080] If both abnormal height sensors can output valid values, the average height values ​​of the two abnormal height sensors are calculated, and the corresponding air springs of the two abnormal height sensors are adjusted according to the average value; otherwise, the air springs are not adjusted. The method for determining the valid value is as follows: if the abnormal height sensor can output a height value and it does not exceed the adjustment limit allowed by the vehicle chassis, then the abnormal height sensor is considered to output a valid value; if the abnormal height sensor can output a height value but the height value exceeds the adjustment limit allowed by the vehicle chassis, or the height value output by the abnormal height sensor is empty or the height value is garbled, then the abnormal height sensor is considered not to output a valid value.

[0081] If the height value reads the limit of the vehicle chassis's adjustable range, it indicates that the vehicle's height has exceeded the normal range and adjustment is required. In this case, the air spring requiring adjustment is first determined based on the abnormal height sensor reading. Then, the air spring of the axle is adjusted based on the average of the two height values ​​detected by the axle. By obtaining the average of the two height values, the actual height of the vehicle is more accurately reflected, resulting in more precise air spring adjustment. Judging the average value further avoids situations where the air spring cannot be adjusted due to an excessively high height sensor output value.

[0082] Figure 4 This is a schematic diagram of the abnormal adjustment strategy of the coaxial abnormal height sensor in this invention. When the left front height sensor and the right front height sensor are both abnormal, the air spring is adjusted based on whether the abnormal sensor outputs a valid value.

[0083] If both abnormal height sensors have valid values, calculate the average value of the height values ​​of the left front height sensor and the right front height sensor, and then adjust the air springs corresponding to the left front height sensor and the right front height sensor according to the average value.

[0084] If one or both of the height sensors fail to output valid values, it indicates that the data returned by the sensors is unreliable. In this case, do not adjust the air spring to avoid adjustment errors caused by abnormal data.

[0085] When the two abnormal height sensors are on the same side, the air springs corresponding to the abnormal height sensors are adjusted simultaneously, specifically as follows:

[0086] The following operations are performed on the two abnormal height sensors respectively: the air spring corresponding to the abnormal height sensor is adjusted according to the height value of the normal height sensor coaxial with the abnormal height sensor.

[0087] If the abnormal height sensor cannot output a valid value, it indicates that the data returned by the sensor is unreliable. In this case, the air springs of the axles need to be adjusted according to the height values ​​detected by the normal height sensors on the front and rear axles. By using the data detected by the normal height sensors, the accuracy of the air spring adjustment is ensured, and adjustment errors caused by abnormal data are avoided.

[0088] Figure 5 This is a schematic diagram of the abnormal adjustment strategy for the same-side abnormal height sensor in this invention. When the left front height sensor and the left rear height sensor are both abnormal, the left front air spring is adjusted according to the height value output by the right front height sensor, and the left rear air spring is adjusted according to the height value output by the right rear height sensor.

[0089] 3. If three or four of the abnormal height sensors are present, do not adjust the air spring.

[0090] This means that when the vehicle's height sensor experiences significant anomalies, the system will choose not to adjust the air spring to avoid adjustment errors caused by data errors. In this situation, the vehicle's height cannot be precisely controlled, therefore, other measures are needed to handle this anomaly.

[0091] After obtaining the air spring that needs adjustment, the following operations are also required: real-time monitoring of the temperature and pressure of the air tank, and selection of the air spring pumping device based on the temperature and pressure. When the temperature and pressure of the air tank are within the normal operating range, the air tank is used to pump the air spring; otherwise, a compressor is used to pump the air spring.

[0092] To ensure the accuracy and real-time performance of this parameter, the air spring system checks and updates the relevant data every 10 milliseconds. This high-frequency detection allows for timely reflection of changes in the air spring system's state, providing the control system with more precise data and thus ensuring vehicle safety and comfort.

[0093] Example 2

[0094] like Figure 6 As shown, the present invention also provides a monitoring and adjustment device for an air spring, including a receiving module, a judgment module and an adjustment module.

[0095] The receiving module uses height sensors to detect the real-time height of the vehicle's four wheels, obtaining the height value for each wheel. This module continuously receives and updates height values, providing real-time data for monitoring and adjusting the air springs. This ensures the system can promptly acquire information about changes in vehicle height, providing a basis for subsequent judgment and adjustment.

[0096] The judgment module is connected to the receiving module and is used to determine whether the corresponding height sensor is malfunctioning based on the height value. If a malfunctioning height sensor is found, the module determines the air spring that needs adjustment based on the number, location, and height value of the malfunctioning height sensors. This module sets certain judgment criteria, such as a preset height value range, to determine whether the height sensor is working properly. Through these judgment criteria, abnormalities in the height sensor can be detected in a timely manner, providing a basis for subsequent adjustment operations.

[0097] The adjustment module is connected to the judgment module and is used to adjust the air spring that needs to be adjusted.

[0098] In summary, the air spring monitoring and adjustment device provided by this invention achieves real-time monitoring and adjustment of the vehicle air spring system through the coordinated action of the receiving module, the judgment module, and the adjustment module, thereby improving the stability and safety of vehicle operation.

[0099] Example 3

[0100] The present invention also provides a monitoring and adjustment device for an air spring, comprising:

[0101] Memory: Used to store the computer-executed program for the monitoring and adjustment method of the air spring described above. This program contains various algorithms and logic for implementing the monitoring and adjustment of the air spring.

[0102] Processor: Used to retrieve computer programs from memory and execute monitoring and adjustment methods for the air spring.

[0103] The processor reads the program from the memory and performs data processing and adjustment operations according to the program's instructions to achieve real-time monitoring and adjustment of the air spring.

[0104] Example 4

[0105] The present invention also provides a storage medium storing a computer-executable program, which is invoked by a processor to perform the steps of the above-described method for monitoring and adjusting the air spring. This storage medium is a computer hard drive, flash memory, optical disc, or other readable and writable storage device. Through this storage medium, the computer-executable program is saved and invoked by the processor when needed to realize the monitoring and adjustment functions of the air spring.

[0106] Specifically, when the processor needs to retrieve a computer program from the storage medium, it reads the program code from the storage medium and loads it into memory. Then, the processor executes the various steps of the air spring monitoring and adjustment method according to the instructions of the program code, including receiving real-time height values ​​of the four wheels of the vehicle, determining whether the height sensor is malfunctioning, and performing corresponding adjustment operations based on the malfunction.
