[0037] Combination Figure 1 As shown, according to a specific embodiment of the present invention, an air suspension control system is provided.

[0038] Specifically, such as Figure 1 As shown, an air suspension control system includes: a main control system 10 for receiving control information and generating control signals based on the control information, wherein the control information includes at least current information and displacement sensor information sent to the main control system 10 in real time by the target component; a drive system 30 for outputting target power based on the control signals to drive the air suspension system 50 to move to the target position; and a redundant control system 20 for interacting with the main control system 10 and detecting the operating status of the main control system 10. If the operating status of the main control system 10 is determined to be a fault state, the redundant control system 20 controls the drive system 30 to output the target power based on the control signals.

[0039] In this embodiment, by setting the main control system 10 to receive current information and displacement sensor information, the system can generate control signals more accurately, drive the system 30 to output target power, thereby enabling the air suspension system 50 to move to the target position, improving the stability and accuracy of the system. By setting a redundant control system, the system can take over control in time when the main control system 10 fails, ensuring the normal operation of the air suspension system 50, reducing the impact of the failure on the system, and improving the stability and accuracy of the system.

[0040] The main control system 10 and the drive system 30 are connected via communication methods such as hardwire, SPI, and I2C. During operation, the main control system 10 sends control signals to the drive system 30.

[0041] The aforementioned redundant control system 20 is directly powered and controlled by the power module. The redundant control system 20 is connected to the drive system 30 through communication methods such as hardwire, SPI, and I2C to prevent the air suspension function from becoming uncontrollable when the main control system 10 fails. It also monitors the output control signals of the main control system 10. When the main control system 10 fails, it responds quickly and the redundant control system 20 takes over the control. The redundant control system 20 also processes the output control signals to improve signal stability.

[0042] The aforementioned drive system 30 consists of an axle drive, which is controlled by a control signal output from the control unit to output different drive voltages to control the air suspension height of the subsequent stage.

[0043] The aforementioned air suspension system 50 converts the output voltage signal of the axle drive into a current signal to adjust the height of the air suspension.

[0044] During the adjustment of the air suspension height, the current detection chip and sensor of the current detection system 40 monitor the air suspension height and drive current in real time. The main control system 10 receives the current information and displacement sensor information, compares the actual current with the target current, and forms a closed-loop PID regulation. By adjusting the output control signal parameters, the drive current and air suspension height are dynamically adjusted, a high-precision feedback circuit is built to improve the accuracy and stability of the circuit. When the main control system fails, the redundant control system reads the parameters calculated by the main control system and outputs the control signal to keep the air suspension system 50 working normally.

[0045] Furthermore, the target component includes: a current detection system 40, which receives current information from the air suspension system 50 in real time and transmits it to the main control system 10 in real time.

[0046] In some alternative embodiments, the current detection system 40 and the main control system 10 interact with each other, and more sensors can be added to monitor the stability and peak value of the current to ensure the safe operation of the system.

[0047] In some alternative embodiments, the current detection system 40 described above can use machine learning algorithms to learn normal current patterns and automatically trigger diagnostic procedures when an anomaly is detected.

[0048] In some alternative embodiments, the current detection system 40 described above can be connected to the Internet, allowing remote monitoring of the current status of the suspension system and remote adjustment as necessary.

[0049] The current detection system 40 can monitor the operating status of the air suspension system in real time, including the magnitude and changes in current, thereby ensuring the normal operation of the suspension system. By monitoring abnormal changes in current, the system can quickly identify potential faults or damage, thereby reducing maintenance time and costs. The real-time transmitted current information can be used for safety-related decisions, such as automatically adjusting the suspension system when abnormal current is detected to prevent rollovers or other safety accidents. The main control system 10 can adjust the parameters of the suspension system according to the current information to adapt to different road conditions and driving habits, improving ride comfort.

[0050] Furthermore, the target component also includes a sensor module 60, which receives displacement sensor information from the air suspension system 50 in real time and transmits it to the main control system 10 in real time.

[0051] In some alternative embodiments, the sensor module 60 described above may be designed to integrate different types of sensors (such as accelerometers and gyroscopes) to provide more comprehensive suspension system status information.

[0052] In some alternative embodiments, the sensor module 60 described above may be designed to use wireless technologies such as Bluetooth or Wi-Fi to transmit sensor data, reducing the use of wiring harnesses and improving vehicle flexibility.

[0053] In some alternative embodiments, the sensor module 60 described above may be designed to upload sensor data to the cloud for in-depth analysis and use machine learning techniques to optimize the performance of the suspension system.

[0054] In some alternative embodiments, the sensor module 60 described above may be designed to be integrated with the vehicle's dynamic stability control system (such as ESP) to provide better vehicle handling and stability.

[0055] Displacement sensors provide precise data on the current state of the suspension system, enabling the main control system to make finer adjustments. The sensor module can detect changes in vehicle load and adjust the suspension system in real time to maintain vehicle stability and balance.

[0056] Furthermore, the redundant control system 20 includes a signal monitoring module 21, which monitors the operating status of the main control system 10 in real time. If the main control system 10 is determined to be in a fault state, the signal monitoring module 21 issues a fault detection message. When the main control system 10 fails, the signal monitoring module 21 responds quickly and the redundant control system 20 takes over control.

[0057] By setting up a redundant control system 20, even if the main control system 10 fails, the redundant control system 20 can immediately take over, ensuring the vehicle's suspension system continues to operate and reducing safety risks caused by system failure. The redundant control system can seamlessly take over, avoiding interruptions to the vehicle's suspension system due to system failure and maintaining normal vehicle operation. When the main control system 10 fails, the redundant control system 20 not only maintains operation but also smoothly returns control to the main control system 10 after the fault is repaired. The signal monitoring module 21 can monitor the status of the main control system 10 in real time, promptly detect problems, and provide a basis for rapid response.

[0058] Furthermore, the redundant control system 20 also includes a redundant control module 22, which responds to monitoring fault information and controls the drive system 30 to output target power based on control signals.

[0059] In this embodiment, the redundant control module 22 can respond quickly to fault conditions, reducing system recovery time. Even if the main control system 10 fails, the redundant control module 22 can maintain the basic functions of the system, avoiding interruption of the vehicle suspension system due to system failure.

[0060] Furthermore, the redundant control system 20 also includes a signal processing module 23, which is used to preprocess the control signal, including voltage regulation and noise reduction.

[0061] Through voltage regulation and noise reduction, the signal processing module provides clearer and more accurate control signals. High-quality control signals contribute to more stable system operation and reduce instability caused by signal interference. Pre-processed signals can be processed more quickly by the redundant control module 22, improving system response speed. The signal processing module 23 can be adjusted according to different needs, increasing system flexibility. Through voltage regulation and noise reduction, the signal processing module 23 enhances the system's compatibility with other systems.

[0062] Furthermore, the main control system 10 includes a dynamic adjustment module 11, which receives current information and displacement sensor information, dynamically adjusts the current information and displacement sensor information based on an internal algorithm, generates adjusted current information and adjusted displacement sensor information, and sends the adjusted current information and adjusted displacement sensor information to the drive system 30 to drive the air suspension system 50 to move to the target position.

[0063] In some alternative embodiments, the dynamic adjustment module 11 described above can continuously improve the internal algorithm to enhance the response speed and adjustment accuracy of the suspension system.

[0064] In some alternative embodiments, the dynamic adjustment module 11 described above may incorporate machine learning algorithms to enable the system to automatically adjust suspension settings based on driving habits and road conditions.

[0065] In some alternative embodiments, the dynamic adjustment module 11 described above may consider other parameters in addition to current and displacement information, such as vehicle speed, acceleration, vehicle tilt angle, etc., to achieve more comprehensive suspension adjustment.

[0066] In some alternative embodiments, the dynamic adjustment module 11 described above can perform fault diagnosis and prediction: by analyzing dynamic adjustment data, it can predict potential system faults and wear.

[0067] The dynamic adjustment module 11 precisely regulates current and displacement information to ensure that the air suspension system 50 accurately reaches the target position. The dynamic adjustment module 11 receives and processes sensor information in real time, quickly responding to road surface changes and driving demands. Through dynamic adjustment, the dynamic adjustment module 11 automatically adjusts suspension stiffness or height according to road conditions, improving ride comfort. Dynamic adjustment helps maintain vehicle stability and reduce body roll during high-speed driving or cornering. The dynamic adjustment module 11 can self-adjust according to different loads, road types, and driving modes to adapt to various driving conditions. Internal algorithms optimize current usage, reducing unnecessary energy consumption and thus improving energy efficiency.

[0068] Furthermore, the correction module 12 is used to correct the adjusted current information and the adjusted displacement sensor information.

[0069] The correction module 12 can correct deviations and errors in sensor data, improving the precision of suspension system adjustments. By correcting inaccurate signals, it enhances the reliability and stability of the entire suspension system. The correction module 12 optimizes suspension system performance, ensuring optimal performance under various road conditions and driving conditions. By precisely correcting sensor information, it improves the suspension system's response speed and adjustment quality, thereby enhancing ride comfort. The correction module 12 improves vehicle handling, especially during high-speed driving or emergency avoidance. By reducing unnecessary suspension system adjustments, the correction module helps reduce system wear and maintenance costs.

[0070] Furthermore, the dynamic adjustment module 11 includes: a signal receiving module 111, which receives current information and displacement sensor information; a comparison module 112, which compares the current information with a preset current value and compares the displacement sensor information with a preset displacement value; and an adjustment module 113, which adjusts the current information and displacement sensor information to generate adjusted displacement sensor information when the current information is less than the preset current value and the displacement sensor information is less than the preset displacement value.

[0071] The comparison module 112 helps the system identify and compensate for performance deviations by comparing real-time data with preset values. The adjustment module 113 adjusts the suspension system based on the comparison results to adapt to road conditions and driving behavior, improving ride comfort. Dynamic adjustment of the suspension system improves vehicle stability at different speeds and during cornering. Adjustment when current information is below a preset value helps optimize the suspension system's energy efficiency and reduce unnecessary energy consumption. The module can automatically adjust according to different loads and road conditions, improving the adaptability of the suspension system.

[0072] According to another aspect of the present invention, a vehicle is provided, including an air suspension control system, which is the air suspension control system of the above embodiment. The air suspension control system includes: a main control system 10, configured to receive control information, and the main control system 10 generates a control signal based on the control information, wherein the control information includes at least current information and displacement sensor information sent to the main control system 10 by a target component; a drive system 30, which outputs a target power based on the control signal to drive the air suspension system 50 to move to a target position; and a redundant control system 20, which interacts with the main control system 10 and is configured to detect the operating state of the main control system 10. If the operating state of the main control system 10 is determined to be a fault state, the redundant control system 20 controls the drive system 30 to output the target power based on the control signal.

[0073] In this embodiment, by setting the main control system 10 to receive current information and displacement sensor information, the system can generate control signals more accurately, drive the system 30 to output target power, thereby enabling the air suspension system 50 to move to the target position, improving the stability and accuracy of the system. By setting a redundant control system, the system can take over control in time when the main control system 10 fails, ensuring the normal operation of the air suspension system 50, reducing the impact of the failure on the system, and improving the stability and accuracy of the system.

[0074] like Figure 2 As shown in another embodiment of this application, the present invention provides a method for operating an air suspension control system, the specific steps of which are as follows.

[0075] Step S100: The redundant control system 20 is directly powered and controlled by the power supply. When the car is powered on, the redundant control system 20 monitors the control signal of the main control system 10 in real time. When the main control system 10 is functioning normally, it controls the air suspension. When a fault is detected in the main control system 10, the redundant control system 20 takes over the control to ensure the normal operation of this function during driving.

[0076] Step S101: After the redundant control system 20 detects a fault in the main control system 10, the redundant control system 20 reads the result calculated by the internal algorithm of the main control system 10 and continues to output control signals to achieve normal operation.

[0077] Step S110: When the main control system 10 is functioning normally, the main control system 10 collects the working current information and suspension height information of the air suspension in real time, and adjusts the control signal parameters in real time through internal algorithms to achieve precise control of the air suspension.

[0078] Step S111: The signal processing module in the redundant control system 20 processes the signals output by the main control system 10 and the redundant control system 20, including preprocessing such as voltage stabilization and noise reduction, to make the control signals more accurate.

[0079] Step S112: The drive system 30 outputs voltage values ​​of different parameters according to the control signal to drive the air suspension to work.

[0080] Step S113: The air suspension system converts the voltage value into operating current to adjust the height of the air suspension.

[0081] Step S114: The current detection system 40 and the sensor module 60 dynamically monitor the working current and suspension height during the adjustment of the air suspension, and provide real-time feedback to the main control system 10.

[0082] Step S115: The main control system 10 collects feedback signals and dynamically adjusts the output control signals through internal algorithms until dynamic balance is achieved, thereby reducing the impact of voltage fluctuations during vehicle operation and improving the stability of the entire control system.

[0083] The redundant control system 20 takes over the operation mechanism as follows: When the main control system 10 fails, the signal monitoring module 21 detects the abnormal output function of the main control system 10 and transmits a fault signal to the redundant control module 22, causing the redundant control module 22 to take over the control operation. It receives the PID-adjusted data sent by the main control system 10 in real time through the communication interface and outputs control signals.

[0084] Closed-loop feedback principle: The current detection system 40 interacts with the air suspension system 50, acquiring the operating current driving the air suspension in real time. The sampled current is converted into a sampled voltage via a current sampling chip and a sampling resistor, and fed back to the AD port of the main control chip in the main control system 10. The main control system 10 compares the actual current with the target current to form a closed-loop PID control. By dynamically adjusting the output signal parameters, the control accuracy is continuously corrected, achieving precise control of the air suspension.

[0085] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0086] (1) Design the main control system 10 and the redundant control system 20 to control the drive voltage of the bridge drive module to realize the function of adjusting the air suspension height.

[0087] (2) The redundant control system 20 is directly powered and controlled by the power supply module. Internally, it includes a redundant control module, a main control output signal monitoring module, and a signal processing module. The redundant control module prevents the air suspension from becoming uncontrollable due to a failure of the main control module during vehicle operation, greatly improving driving safety. The monitoring module monitors the main control system's output signal in real time and quickly takes over control when the main control module fails. The signal processing module processes the output signal to improve signal stability. Furthermore, the operating current and air suspension height are collected in real time by the current detection module and sensors and fed back to the main control system. The main control system dynamically adjusts the output signal parameters using its internal algorithm to achieve closed-loop regulation, greatly improving control accuracy.
