According to the height adjustment of the suspension system of the vehicle, the suspension system and the vehicle, whether the adjustment condition is met or not is judged based on the difference value between the suspension height data sensed by the sensor and the target height data, and when the adjustment condition is judged to be met, after operation is conducted through the fuzzy controller and the PID controller, the height of the suspension system is adjusted. A control signal is output to control the solenoid valve to adjust the height of the suspension. At least one of the problems that overshoot is too large, response time is too long, and dynamic performance of a nonlinear system is poor when the air spring is adjusted due to the fact that the control range is not clear is solved.

    本申请提供车辆的悬架系统的高度调节、悬架系统及车辆,基于传感器感测的悬架高度数据与目标高度数据的差值判断是否满足调节条件,当判断满足调节条件,通过模糊控制器和PID控制器运算后,输出控制信号来控制电磁阀以调节所述悬架的高度。解决了由于控制范围不明确造成对空气弹簧调节时超调量过大与响应时间过长,非线性系统动态性能较差等至少之一问题。
