The invention discloses a chassis obstacle avoidance system and method, and the system comprises a radar sensor, a vehicle speed sensor, a high-precision map device and an automobile control unit, and the automobile control unit determines the size of each obstacle and the collision time of the vehicle and each obstacle from the information of the obstacles around the vehicle; and re-planning a driving path based on the high-precision map data when determining that the vehicle has a chassis bottom dragging risk based on the sizes of the obstacles and the corresponding collision time in combination with the high-precision positioning information of the vehicle, or re-planning the driving path when the chassis bottom dragging risk cannot be avoided by re-planning the driving path, or re-planning the driving path when the chassis bottom dragging risk cannot be avoided by re-planning the driving path. The corresponding preset obstacle avoidance strategy is adopted based on whether the collision risk exists around the vehicle or not, so that the bottom dragging risk of the vehicle is avoided, or the loss and the risk are reduced to the minimum, and the safety and the reliability of vehicle driving are greatly improved.

    本发明公开了一种底盘避障系统及避障方法,系统包括:雷达传感器、车速传感器、高精度地图设备和汽车控制单元,汽车控制单元从车辆周围障碍物信息中确定各个障碍物尺寸以及车辆与各个障碍物的碰撞时间,并在基于各个障碍物尺寸及对应的碰撞时间,结合车辆的高精度定位信息确定车辆存在底盘拖底风险时,基于高精度地图数据重新规划行驶路径,或是在无法通过重新规划行驶路径方式规避底盘拖底风险时,基于车辆周围是否存在碰撞风险采取对应的预设避障策略,以避免车辆出现拖底风险,或是将损失与风险降至最低,大大提高车辆行驶的安全性和可靠性。
