The invention provides an automatic driving vehicle and an obstacle display method thereof, and belongs to the technical field of vehicle obstacle information display. In consideration of different road bending degrees in a vehicle driving process, when a vehicle is in an automatic driving state and the vehicle is driven on a large turning radius or a straight road, a position relationship between an obstacle and the vehicle is displayed under a Frenet coordinate system, so that the problem that the relative position of the obstacle and the vehicle is wrongly displayed by adopting a vehicle body coordinate system under the condition is avoided; when the vehicle runs on the road with the small turning radius, the position relation between the vehicle and the obstacle is displayed by adopting the vehicle body coordinate system, and the problem that the relative position relation between the vehicle and the obstacle displayed by the Frenet coordinate system is incorrect under the condition is avoided. The corresponding coordinate system is selected according to different conditions in the vehicle driving process, the relative position relation, close to the actual condition, of the obstacle and the vehicle is better displayed to passengers, and the user experience is further improved.

    本发明提出一种自动驾驶车辆及其障碍物显示方法,属于车辆障碍物信息显示技术领域。考虑到车辆行驶过程中道路弯曲程度不同,在车辆自动驾驶状态下,车辆在大转弯半径或直线道路上行驶时,在Frenet坐标系下显示障碍物与车辆位置关系,避免了在这种情况下采用车身坐标系障碍物与车辆相对位置会出现显示错误的问题;在车辆在小转弯半径道路上行驶时,采用车身坐标系显示车辆与障碍物的位置关系,避免了在这种情况下Frenet坐标系显示车辆与障碍物相对位置关系不正确的问题。本发明根据车辆行驶过程中的不同情况选择对应的坐标系,更好地向乘客展示了接近实际情况的障碍物与车辆的相对位置关系,进一步提升用户体验。
