A vehicle safety system within an autonomous or semi-autonomous vehicle may predict and avoid collisions between the vehicle and other moving objects in the environment. The vehicle safety system may determine one or more perturbed trajectories of another object in the environment, such as by perturbing a state parameter of a perceived trajectory associated with the object. Each perturbation trajectory may be evaluated to determine whether it intersects or may collide with a planned trajectory of the vehicle. In some examples, the vehicle safety system may aggregate analysis results of the plurality of perturbation trajectories to determine a collision probability and/or an additional weight or adjustment factor associated with a collision prediction, and may determine an action to be taken by the vehicle based on the collision prediction and the probability.

    自主或半自主车辆内的车辆安全系统可以预测并避免车辆与环境中其他移动对象之间的碰撞。车辆安全系统可以确定环境中另一对象的一个或多个扰动轨迹,例如通过扰动与对象相关联的感知轨迹的状态参数。每个扰动轨迹可以被评估,以确定它是否与车辆的规划轨迹相交或可能相撞。在一些示例中,车辆安全系统可以聚合多个扰动轨迹的分析结果,以确定碰撞概率和/或与碰撞预测相关联的附加权重或调整因素,并且可以基于碰撞预测和概率确定车辆要采取的动作。
