The invention discloses a control method for vehicle body height compensation of a semi-active suspension, a vehicle is provided with an electronic stability program controller and a semi-active suspension controller, and wheel speed sensors and air springs are arranged at tires of the vehicle; the adjusting method comprises the steps that S1, a vehicle travels for the first time; S2, the electronic stability program controller judges whether the vehicle is provided with a spare tire; S3, the electronic stability program controller sends a second tire position signal to the semi-active suspension controller; S4, the semi-active suspension controller calculates a first target height according to the rolling radius difference value of the radius of the tire and the radius of the spare tire in the design state; the semi-active suspension controller adjusts the air spring to reach a first target height; and S5, the semi-active suspension controller adjusts the air spring to reach the preset height. The defect that the vehicle body height is reduced due to the small rolling radius of the spare tire is overcome, and the driving safety and comfort are improved.

    本发明公开一种半主动悬架的车身高度补偿的控制方法,车辆具备电子稳定程序控制器和半主动悬架控制器,车辆的轮胎处均设有轮速传感器和空气弹簧;调节方法包括:步骤S1:车辆行驶第一时间;步骤S2:电子稳定程序控制器判断车辆是否具有备胎;步骤S3:电子稳定程序控制器向半主动悬挂控制器发出第二轮胎位置信号;步骤S4:半主动悬挂控制器根据轮胎与备胎半径的设计状态下的滚动半径差值计算第一目标高度;半主动悬挂控制器调整空气弹簧达到第一目标高度;步骤S5:半主动悬挂控制器调整空气弹簧达到预设高度。本发明弥补备胎的滚动半径小引起的车身高度降低,提升驾驶安全性及舒适性。
