The invention relates to the field of vehicle vibration reduction, and discloses a vehicle height active adjustable vibration damper system and a vehicle height control strategy. The piston working structure comprises a working cylinder and a large piston rod; a low-pressure oil cavity is formed in the cap shell structure; a small piston rod is fixed to the top of the cap shell structure and inserted into a sleeve in the large piston rod. The low-pressure oil cavity is communicated with the small hollow cavity through a low-pressure runner; the corrugated pipe body wraps the lower section of the working cylinder and forms a high-pressure oil cavity; the shock absorber system is further provided with a plurality of valves, when the vehicle-mounted ECU receives a vehicle height increasing instruction or a vehicle height reducing instruction, the vehicle-mounted ECU controls the oil flow direction through the valves, and the vehicle height is changed by changing the oil pressure difference between the high-pressure oil cavity and the low-pressure oil cavity. According to the shock absorber system and the vehicle height control strategy, the vehicle height can be actively adjusted while shock absorption is conducted through the multiple valves, so that the vehicle height posture can be adjusted in real time according to the road surface condition, and the comfort and driving stability of the vehicle are improved.
本申请涉及车辆减振领域,公开了一种车辆高度主动可调的减振器系统及车高控制策略。包含:活塞工作结构,其包含工作缸和大活塞杆;盖帽壳体结构,其内含低压油腔;盖帽壳体结构顶部固定小活塞杆,小活塞杆插入大活塞杆内的套管中;低压油腔通过低压流道连通小空心腔;波纹管体,包裹于工作缸下段并形成高压油腔;减振器系统还设置多个阀门,当车载ECU接收到车高升高或车高降低指令时,车载ECU经多个阀门控制油液流向,通过改变高压油腔和低压油腔的油压差改变车高。本申请的减振器系统及车高控制策略,能够通过多个阀门在减振的同时进行车辆高度主动调节,使得车辆高度姿态能够根据路面情况实时调整,提高了车辆的舒适性及驾驶稳定性。
