The invention discloses a control method and device of a vehicle suspension shock absorber, a vehicle controller and a storage medium, and relates to the field of vehicle control. The method comprises the steps of obtaining a wheel acceleration signal, a vehicle body posture signal, a vehicle speed signal and a shock absorber stroke signal; according to the wheel acceleration signal and the vehicle speed signal, road surface protrusion working condition identification is carried out; when the vehicle is in the road surface protruding working condition, the actual control current of a shock absorber electromagnetic valve is determined according to the wheel acceleration signal, the vehicle body posture signal, the vehicle speed signal and the shock absorber stroke signal; and the vehicle suspension shock absorber is controlled based on the actual control current, so that discomfort caused by the fact that wheel impact is transmitted to a vehicle body during road surface protrusion impact can be effectively reduced, impact aftershock can be rapidly reduced after road surface protrusion impact, and the riding comfort is improved.

    本申请公开了一种车辆悬架减振器的控制方法、装置、车辆控制器及存储介质,涉及车辆控制领域。通过获取车轮加速度信号、车身姿态信号、车速信号及减振器行程信号;根据所述车轮加速度信号及所述车速信号进行路面凸起工况识别;当所述车辆处于路面凸起工况时,根据所述车轮加速度信号、所述车身姿态信号、所述车速信号及所述减振器行程信号来确定减振器电磁阀的实际控制电流;基于所述实际控制电流对所述车辆悬架减振器进行控制,从而能够有效的减少路面凸起冲击时车轮冲击传递到车身引起的不适,以及在路面凸起冲击后的快速削减冲击余振,提升乘坐舒适性。
