The invention provides an intelligent driving chassis domain uneven road surface self-adaptive control method and system and an automobile, and belongs to the technical field of intelligent driving vehicle control. The method comprises the steps that an automatic driving function is started, and whether an uneven road surface self-adaptive passing mode is started or not is judged on the basis of road condition information of a current driving road surface in combination with the wheel acceleration of the automobile; when the uneven road surface self-adaptive passing mode is started, front road condition data of the vehicle is collected, a real-time data map of the front road condition is drawn, and road surface type division is conducted on the data map according to the concave-convex degree and concave-convex distribution of road surfaces; according to different road surface types, corresponding driving priority control, braking priority control or steering priority control strategies are selected to control the vehicle, the driving state of the vehicle is adjusted in real time, the vehicle can pass through the uneven road surface in a stable and comfortable passing or rapid and safe passing mode, and therefore it is guaranteed that the vehicle is automatically and safely driven on the uneven road surface, and the driving safety of the vehicle is improved. And the safety performance of automatic driving on a special road surface is improved.

    本发明提供智能驾驶底盘域不平路面自适应控制方法、系统及汽车,属于智能驾驶车辆控制技术领域,方法包括:开启自动驾驶功能,基于当前行驶路面的路况信息结合车辆的轮加速度判断是否开启不平路面自适应通过模式;当开启不平路面自适应通过模式,则采集车辆的前方路况数据并绘制前方路况的实时数据地图,并根据路面的凹凸程度和凹凸分布对所述数据地图进行路面类型划分;根据不同的路面类型选择对应的驱动优先控制、制动优先控制或转向优先控制策略控制车辆,实时调整车辆的驾驶状态,实现以平稳舒适通过或快速安全通过的模式通过该不平路面,从而保证车辆在不平路面上的自动安全驾驶,提升了自动驾驶特殊路面的安全性能。
