The invention relates to a vehicle control method and a damping working mode determining method and device.The vehicle control method comprises the steps that running state related data of a vehicle are determined; if the running state related data is within the target state threshold range, determining a target damping working mode corresponding to the target state threshold range; the preset damping working mode is determined based on the asymmetric damping ratio of the vehicle shock absorber, and the asymmetric damping ratio is the ratio of the recovery stroke damping force of the vehicle suspension system to the compression stroke damping force of the vehicle suspension system; and according to the target damping working mode, the sectional area of a throttling hole of an electromagnetic valve of the vehicle is set, so that the vehicle is controlled to operate within the damping range of the target damping working mode. According to the embodiment of the invention, on the basis of the asymmetric damping ratio of the vehicle, the damping working mode of the vehicle can be timely adjusted according to the state of the vehicle in the running process on the current road surface, so that the performance of a shock absorber of a vehicle suspension system is improved, and the vehicle runs more stably.
本说明书涉及一种车辆控制方法、阻尼工作模式确定方法及装置,其中,车辆控制方法包括:确定车辆的运行状态相关数据;若运行状态相关数据位于目标状态阈值范围内,确定目标状态阈值范围所对应的目标阻尼工作模式;预设阻尼工作模式是基于车辆减振器的不对称阻尼比而确定的,不对称阻尼比为车辆悬架系统的复原行程阻尼力和车辆悬架系统的压缩行程阻尼力之比;根据目标阻尼工作模式,设置车辆的电磁阀的节流孔截面积,以控制车辆在所述目标阻尼工作模式的阻尼范围内运行。本说明书实施例能够以车辆的不对称阻尼比为依据,根据车辆在当前路面运行过程中的状态,及时车辆调整阻尼工作模式,从而提高车辆悬架系统的减振器性能,使得车辆运行更加平稳。
