The invention discloses a method and a device for determining the risk of a vehicle track. The maximum risk, possibly brought by a vehicle, of the vehicle in a first limit state when the vehicle is atthe maximum risk is determined during the determination of the risk of the track. For each obstacle in the environment where the vehicle is located, the maximum risk possibly brought to the vehicle by the obstacle is determined on the basis of a second limit state of a behavior, which can be most unfavorable for the vehicle, made by the obstacle. According to the method and the device in the specification, the worst driving environment where the vehicle may be located and the most extreme motion state of the vehicle itself can be used as the basis for determining the track risk, and the comprehensiveness, the forward looking performance and the sensitivity of track risk determination are improved. In addition, the lowest risk bearing capacity of the vehicle and the maximum risk possibly brought by the obstacle to the vehicle can be patterned to a certain extent through the risk area which has a graphic attribute expression mode. The efficiency and intuition of determining the risk ofthe vehicle track can be improved.

    本说明书公开了一种车辆轨迹的风险确定方法及装置,在确定轨迹的风险时,以车辆处于最大风险时的第一极限状态,确定车辆可能为自身带来的最大风险。针对车辆所处环境中的各障碍物,则以障碍物能够做出的对车辆最为不利的行为的第二极限状态为依据,确定障碍物可能对车辆带来的最大风险。本说明书中的方法及装置,能以车辆可能面临的最为恶劣的行驶环境,及车辆自身最为极端的运动状态作为确定轨迹风险的依据,提高轨迹风险确定的全面性、前瞻性和敏感性。此外,本说明书能够通过风险区域这一具有图形属性表达方式将车辆的最低风险承担能力,以及障碍物可能为车辆带来的最大风险一定程度的图形化。有利于提高确定车辆轨迹的风险的效率及直观性。
