The invention provides a target vehicle static state judgment method and device. The judgment method comprises the steps that a first static probability is obtained based on the relative speed of a vehicle and a target vehicle; acquiring a second static probability based on the relative distance between the vehicle and the target vehicle; acquiring a third static probability based on the collision time of the vehicle to the target vehicle; the first static probability, the second static probability and the third static probability are processed to generate an optimal static probability, and if the optimal static probability is larger than a preset probability, the static state of the target vehicle is judged based on the optimal static probability. According to the method, the judgment precision of the static state of the target vehicle can be improved, and the multivariate verification efficiency of the static state in different channels such as speed, distance and collision time is improved through three target vehicle static probability calculation modes.
本申请提出一种目标车辆静止状态的判断方法及装置,所述判断方法包括基于自车与目标车辆的相对速度获取第一静止概率;基于自车与目标车辆的相对距离获取第二静止概率;基于自车对目标车辆的碰撞时间获取第三静止概率;将所述第一静止概率、所述第二静止概率和所述第三静止概率处理生成最优静止概率,若所述最优静止概率大于预设概率,则基于所述最优静止概率判断目标车辆的静止状态。本申请可以提高对目标车辆静止状态的判断精度,通过三种目标车辆静态概率的计算方式,提高了在速度、距离以及碰撞时间等不同渠道的静止状态的多元验证效率。
