The invention belongs to the technical field of vehicle control, and particularly relates to an automobile off-road mode automatic exit control method which comprises a road surface recognition method and a mode exit method. When the vehicle manually enters the off-road mode, the vehicle obtains a signal of a rainfall sensor, judges whether the current weather is rainy and snowy or not, and controls the vehicle to enter the off-road mode if the current weather is rainy and snowy; the vehicle obtains position information and weather information of the current position through the Internet of Vehicles, judges road condition information of the current position, determines whether road slippery or icing early warning information exists or not, and controls the vehicle to enter an off-road mode if the road slippery or icing early warning information exists; and the vehicle judges the road grade and the road material of the current driving road surface according to the position information. The defects in the prior art are overcome, an automatic exit mechanism of an off-road mode is formulated by collecting road conditions and driving conditions, oil consumption can be reduced to the maximum extent, parts of a transmission system are protected, and the fault occurrence rate is reduced.

    本发明属于车辆控制技术领域,具体涉及一种汽车越野模式自动退出控制方法,该控制方法包括路面识别方法和模式退出方法;在车辆手动进入越野模式时,车辆获取雨量传感器的信号,判断当前是否为雨雪天气,若为雨雪天气则控制车辆进入越野模式;车辆通过车联网获取位置信息和当前位置的天气信息,判断当前位置的路况信息,确定是否有道路湿滑或结冰预警信息,若有道路湿滑或结冰预警信息,则控制车辆进入越野模式;车辆根据位置信息判断当前行驶路面的道路等级和道路材质。克服了现有技术的不足,通过对路面情况和驾驶情况的采集,制定越野模式的自动退出机制,能够最大限度降低油耗,保护传动系零部件,降低故障发生率。
