The invention relates to the technical field of vehicles, in particular to a four-wheel drive mode switching method and device of a vehicle, the vehicle and a storage medium. If the current vehicle is in the two-wheel-drive mode, the current rainfall value of the position where the current vehicle is located and the road condition in front of the current vehicle are obtained, and whether the current rainfall value is larger than a preset rainfall value or not and/or whether the road condition in front meets a preset four-wheel-drive mode switching condition or not are judged; if the current rainfall value is larger than the preset rainfall value and/or the front road condition meets the preset four-wheel-drive mode switching condition, the driving mode of the current vehicle is controlled to be switched to the four-wheel-drive mode from the two-wheel-drive mode. Therefore, the problem that the four-wheel-drive mode can only be passively switched when slipping and wheel speed difference are detected, and cannot intervene in advance or needs manual intervention is solved, the situation that the vehicle slips on special road conditions such as rainy days or muddy ground, water pits and hollow sand is avoided, the four-wheel-drive mode is actively switched in advance, and the safety of the vehicle is improved.

    本申请涉及车辆技术领域,特别涉及一种车辆的四驱模式切换方法、装置、车辆及存储介质,其中,方法包括:识别当前车辆的驱动模式;若当前车辆为两驱模式,则获取当前车辆所处位置的当前雨量值和当前车辆的前方路况,并判断当前雨量值是否大于预设雨量值,和/或前方路况是否满足预设的四驱模式切换条件;若当前雨量值大于预设雨量值,和/或前方路况满足预设的四驱模式切换条件,则控制当前车辆的驱动模式由两驱模式切换至四驱模式。由此,解决四驱模式只能在检测到有打滑有轮速差时被动切换,无法提前介入或需要人为介入的问题,避免车辆在下雨天或泥地、水坑、坑洼沙地等特殊路况路面打滑,主动提前切换到四驱模式,提升车辆的安全性。
