The invention discloses a passenger car
air suspension control system. The passenger car
air suspension control system comprises a height sensor, a speed sensor, a
pressure sensor, an air inflation circuit, a
solenoid valve group, a display and set module and a main controller, wherein the air inflation circuit is used for opening and closing of an air bag, and the
solenoid valve group is used for opening and closing of an air deflation circuit of the air bag; the display and set module is used for setting a suspension
system parameter and choosing work
modes; and the main controller is used for receiving the height information of a car body, speed information, the pressure information of an air
storage tank, suspension
system parameter information and work mode information and controlling the opening and closing of the
solenoid valve group according to the information. According to the passenger car
air suspension control system, the various sensors are utilized to monitor the corresponding parameters of a passenger car, the functions of a high position mode, a middle position mode, a low position mode, a side knelt mode, a high speed height mode,
chassis stability, fault query, online parameter calibration and the like are achieved, different road conditions can be adapted, vehicle speed requirements can be met, and perfect maneuverability of the passenger car is guaranteed while riding comfort and comfort of the car are improved.
