The invention relates to the technical field of automatic parking, in particular to a vehicle parking collision early warning method and device.The method comprises the steps that the risk early warning range and the safety distance of each vehicle-mounted ultrasonic radar are calculated according to the driving area of a vehicle, and at least one target vehicle-mounted ultrasonic radar entering the risk early warning range is screened out; the minimum output distance of each target vehicle-mounted ultrasonic radar is determined based on the corresponding safety distance, and collision early warning is carried out when the minimum output distance is smaller than a preset braking threshold value. The risk early warning range and the safety distance can be determined based on the driving area, so that collision early warning is performed when the minimum output distance is smaller than a certain braking threshold value, the early warning accuracy and adaptability are improved, parking collision of the vehicle is effectively avoided, the reliability of automatic parking is improved, and the automatic parking method is safer and more reliable.
本申请涉及自动泊车技术领域,特别涉及一种车辆的泊车碰撞预警方法及装置,其中,方法包括:根据车辆的行驶区域计算每个车载超声雷达的风险预警范围和安全距离,筛选出进入风险预警范围的至少一个目标车载超声雷达,并基于对应的安全距离确定每个目标车载超声雷达的最小输出距离,并在最小输出距离小于预设制动阈值时进行碰撞预警。本申请实施可以基于行驶区域确定风险预警范围和安全距离,从而在最小输出距离小于一定制动阈值时进行碰撞预警,提高预警的准确性和自适应性,有效避免车辆发生泊车碰撞,提高自动泊车的可靠性,更加安全可靠。
