The invention provides an automatic parking collision avoidance method and device, a medium and a vehicle, and relates to the technical field of automatic parking. The method comprises the steps of firstly determining collision time of a vehicle and a target obstacle, and determining a collision risk level of the vehicle based on the collision time; then, based on the motion state of the target obstacle, the safety braking distance and the target vehicle speed of the vehicle under the collision risk level are determined, and parking control is conducted on the vehicle based on the safety braking distance and the target vehicle speed. Therefore, in the parking process, the collision time of the vehicle and the surrounding obstacles is predicted according to the current driving condition, the collision risk levels are divided based on the collision time, and then corresponding deceleration braking control is carried out under the various collision risk levels, so that the vehicle passes through the obstacles in a decelerating mode or is braked, and the vehicle is prevented from colliding with the surrounding obstacles. The collision safety problem of the automatic driving vehicle in the parking process is effectively solved, the safety of automatic parking is improved, and then the parking experience of a user is improved.
本申请提供了一种自动泊车避撞方法、装置、介质及车辆,涉及自动泊车技术领域。该方法首先确定车辆与目标障碍物的碰撞时间,并基于碰撞时间,确定车辆的碰撞风险等级。然后,基于目标障碍物的运动状态,确定车辆在碰撞风险等级下的安全制动距离和目标车速,并基于安全制动距离和目标车速对车辆进行泊车控制。从而,在泊车过程中,通过根据当前的行车情况预测车辆与周围障碍物的碰撞时间,并基于碰撞时间来划分碰撞风险等级,然后在各种碰撞风险等级下进行相应的减速制动控制,以降速通过障碍物或刹停,防止车辆与周围障碍物发生碰撞,有效克服自动驾驶车辆在泊车过程中的碰撞安全问题,提高自动泊车的安全性,进而提升用户的泊车体验。
