The invention relates to a whole vehicle semi-active suspension control method and system, a vehicle and a storage medium, and belongs to the field of vehicle suspension control. The method comprises the steps that a vehicle signal is obtained and analyzed, and vehicle control parameters are obtained; judging the heeling control state of the current vehicle according to the vehicle control parameters; if the current vehicle is in the steady-state roll control state, steady-state roll control damping force is determined according to vehicle control parameters; if the current vehicle belongs to the transient roll control state, whether the current vehicle is in a limit grip control state or not is determined according to the vehicle control parameters; if the current vehicle is not in the limit grip control state, transient roll control damping force is determined according to the vehicle control parameters; if the current vehicle is in the limit grip control state, limit grip control damping force is determined according to the vehicle control parameters; and according to the steady-state roll control damping force, the limit grip control damping force or the transient roll control damping force, determining a shock absorber control target current in combination with road surface characteristics.
本申请涉及一种整车半主动悬架控制方法、系统、车辆及存储介质,属于车辆悬架控制领域。方法包括:获取车辆信号并进行解析,得到车辆控制参数;根据车辆控制参数判断当前车辆所属的侧倾控制状态;若当前车辆属于稳态侧倾控制状态,则根据车辆控制参数确定稳态侧倾控制阻尼力;若当前车辆属于瞬态侧倾控制状态,则根据车辆控制参数确定当前车辆是否处于极限抓地控制状态;若当前车辆不处于极限抓地控制状态,则根据车辆控制参数确定瞬态侧倾控制阻尼力;若当前车辆处于极限抓地控制状态,则根据车辆控制参数确定极限抓地控制阻尼力;根据稳态侧倾控制阻尼力、极限抓地控制阻尼力或瞬态侧倾控制阻尼力,结合路面特性,确定减震器控制目标电流。
