The invention provides a commercial vehicle semi-active suspension control system and method, and belongs to the technical field of automobile control. A cab CDC damper; an acceleration sensor is suspended on the chassis; an acceleration sensor is suspended on the cab; the controller is used for determining first damping and second damping based on the vehicle speed, the opening degree of an accelerator pedal, the opening degree of a brake pedal, the steering wheel angle information, a chassis acceleration signal collected by the chassis suspension acceleration sensor and a cab acceleration signal collected by the cab suspension acceleration sensor, and adjusting the chassis CDC shock absorber based on the first damping and adjusting the second damping based on the cab acceleration signal collected by the cab suspension acceleration sensor. And adjust the cab CDC damper based on the second damping. The damping of the chassis CDC shock absorber and the damping of the cab CDC shock absorber are adjusted, so that the posture change of the cab is effectively restrained, and the technical problem that the riding comfort of a driver is poor due to the fact that the suspension control effect of a commercial vehicle is not ideal in the prior art is solved.

    本发明提供一种商用车半主动悬架控制系统及控制方法,属于汽车控制技术领域,该系统包括:底盘CDC减振器;驾驶室CDC减振器;底盘悬上加速度传感器;驾驶室悬上加速度传感器;控制器,用于基于车速、油门踏板开度、制动踏板开度和方向盘转角信息,以及底盘悬上加速度传感器采集的底盘加速度信号和驾驶室悬上加速度传感器采集的驾驶室加速度信号,确定第一阻尼和第二阻尼,并基于第一阻尼调节底盘CDC减振器,且基于第二阻尼调节驾驶室CDC减振器。本发明通过对底盘CDC减振器和驾驶室CDC减振器的阻尼进行调整,有效抑制驾驶室的姿态变化,解决现有技术方案对商用车的悬架控制效果不理想,导致驾驶员乘坐舒适性差的技术问题。
