The invention relates to a vehicle control method and device. According to the technical scheme of the invention, a wheel acceleration a of a driving wheel of a vehicle and a wheel acceleration change rate j of wheels of the vehicle can be monitored; if it is monitored that a wheel acceleration of the driving wheel of the vehicle and the wheel acceleration change rate j of the wheels of the vehicle meet initial preset conditions, driving parameters of the driving wheel are obtained, wherein the driving parameters are obtained according to the wheel acceleration of the driving wheel of the vehicle and the wheel acceleration change rate of the wheels of the vehicle within a preset time period; according to the driving parameters and a terrain mapping relation between the driving parameters and a terrain, an actual target terrain where the vehicle is currently located is obtained; a control mode of the vehicle is switched according to the actual target terrain. Therefore, the terrain where the vehicle is located is recognized through the driving parameters related to the wheel speed in the vehicle acceleration process, and the vehicle is controlled.
本申请涉及一种车辆控制方法和装置。根据本申请的技术方案,可以监测所述车辆的驱动轮的车轮加速度a和车轮加速度变化率j;若监测到所述车辆的驱动轮的车轮加速度a和车轮加速度变化率j满足起始预设条件,获取所述驱动轮的行驶参数;其中,所述行驶参数根据预设时间段内所述车辆的驱动轮的车轮加速度、车轮加速度变化率得到;根据所述行驶参数和行驶参数与地形的地形映射关系,得到车辆当前所处的实际目标地形;根据所述实际目标地形,切换车辆的控制模式。由此,通过车辆加速过程中与车轮轮速相关的行驶参数来识别车辆所处的地形,并对车辆进行控制。
