The invention belongs to the technical field of air suspensions, and particularly relates to a vehicle air suspension system, a vehicle and a vehicle body height control method. A vehicle body height control device is arranged on a vehicle body, and height sensors are arranged at height measuring points of any three positions of the left front position, the right front position, the left rear position and the right rear position of the vehicle body and used for measuring vehicle body height values of the corresponding positions. The vehicle body height value corresponding to the height measuring point without the height sensor is deduced by combining the spatial position relation among the four height measuring points on the vehicle body, and then the vehicle body height is controlled according to the vehicle body height values corresponding to the four height measuring points. By the adoption of the method, the precision of controlling the height of the vehicle body only through three height sensors can be greatly improved, high control precision can be guaranteed without four height sensors, the cost performance is higher, and the cost is lower.
本发明属于空气悬架技术领域,具体涉及一种车用空气悬架系统、车辆及车身高度控制方法。车身上设置有车身高度控制装置,在车身的左前位置、右前位置、左后位置以及右后位置中的任意三个位置的高度测量点设置高度传感器用于测量对应位置的车身高度值,根据测量出的三个车身高度值,结合车身上的四个高度测量点之间的空间位置关系推导出未设置高度传感器的高度测量点对应的车身高度值,进而根据以上四个高度测量点对应的车身高度值对车身高度进行控制。采用本发明的方法可大大提高能够仅采用三个高度传感器对车身高度进行控制的精度,无需采用四个高度传感器即可保障较高的控制精度,性价比更高,成本更低。
