A suspension control method, system and device and a computer readable storage medium belong to the field of suspension systems, and comprise the following steps: when it is determined that a target vehicle exists in a lane close to an own vehicle, calculating according to a windward area, a relative speed, a relative distance, a preset influence factor and an own vehicle weight of each target vehicle; respectively obtaining a transverse motion coefficient of each target vehicle; whether the absolute value of the sum of the transverse motion coefficients of all the target vehicles is larger than a first threshold value and whether the minimum relative distance is smaller than a second threshold value or not is judged, if yes, the damping force of the suspension is increased, the left side of the suspension is increased when the transverse motion coefficient is positive, and the right side of the suspension is increased when the transverse motion coefficient is negative; and if not, the suspension damping force and the suspension height are kept unchanged. According to the method, the target vehicle which is located on the lane close to the vehicle and possibly affects the stability of the vehicle can be analyzed in advance, and the suspension is actively adjusted to prevent the vehicle from being affected by the target vehicle to tilt.
一种悬架控制方法、系统、设备及计算机可读存储介质,属于悬架系统领域,包括在判定自车临近车道存在目标车辆时,根据各个目标车辆的迎风面积、相对速度、相对距离、预设的影响因数、以及自车车重计算,分别得到每个目标车辆的横向运动系数;判断所有目标车辆的横向运动系数的总和的绝对值是否大于第一阈值且最小的相对距离是否小于第二阈值,若是,则调高悬架阻尼力,并在横向运动系数为正时调高悬架左侧,在横向运动系数为负时调高悬架右侧;若否,则保持悬架阻尼力和悬架高度不变。本申请能够提前对处在与自车临近车道的可能影响自车稳定性的目标车辆进行提前分析,并主动调节悬架避免自车受目标车辆影响产生侧倾。
