The invention discloses a vehicle driving mode switching method which comprises the following steps: in response to the detection that a vehicle is in an intelligent gear, obtaining target parameters for estimating rolling resistance and judging a slipping condition; calculating a rolling resistance coefficient when the vehicle runs based on the parameters acquired by the vehicle, judging whether wheels of the vehicle slip or not, and calculating a ground attachment coefficient of the wheels when judging that the wheels slip; and determining a terrain mode of a current driving area of the vehicle based on at least one of the rolling resistance coefficient, the ground adhesion coefficient and the wheel slip condition, and switching a driving mode of the vehicle to a driving mode corresponding to the terrain mode of the current driving area. The invention further provides a vehicle driving mode switching device corresponding to the vehicle driving mode switching method and the vehicle.

    本申请公开了一种车辆驾驶模式切换方法,所述方法包括:响应于检测到车辆处于智能档位,获取用于估算滚动阻力和判断打滑情况的目标参数;基于所述车辆获取的所述参数计算所述车辆行驶时的滚动阻力系数,同时判断所述车辆的车轮是否出现打滑,并在判断所述车轮出现打滑时计算所述车轮的地面附着系数;基于所述滚动阻力系数、所述地面附着系数和所述车轮打滑情况中的至少一者确定所述车辆的当前行驶区域的地形模式,将所述车辆的驾驶模式切换到与所述当前行驶区域的地形模式对应的驾驶模式。本申请还提供了与所述车辆驾驶模式切换方法相应的车辆驾驶模式切换装置及车辆。
