The invention discloses an electric vehicle sand mode control method and system and an electric vehicle. The control method comprises the following steps: identifying a current driving road section through collected real-time road condition information; when the driving road section is a desert and the real-time vehicle speed is larger than a set speed threshold value, the automobile starts a sand mode and enters a four-wheel drive mode, the tire pressure of tires is reduced to a set pressure value, corresponding control strategies are selected according to different slopes, and corresponding control strategies can also be selected according to the temperature of a battery cell. According to the method, the sand land mode is started, and the corresponding control strategies are selected according to different gradients and the temperatures of the battery cells, so that the electric automobile can smoothly run in the desert environment, the performance of the automobile is guaranteed, the battery can be effectively protected, and the safety of a driver is better guaranteed.

    本发明公开了一种电动汽车沙地模式控制方法、控制系统及电动汽车。该控制方法包括:通过采集的实时路况信息识别当前行驶路段;当行驶路段为沙漠且实时车速大于设定的速度阈值时,汽车开启沙地模式,汽车进入四驱模式,并将轮胎的胎压降至设定的压力值,并根据不同的坡度选择对应的控制策略,还可以根据电芯的温度选择对应的控制策略。本发明通过开启沙地模式,并根据不同的坡度和电芯的温度选择对应的控制策略,使电动汽车能够顺利的在沙漠环境中行驶,保障车辆性能的同时,可以有效的保护电池,更好的保障了驾驶员的安全。
