The invention discloses a reversing speed limit area adjusting method and system based on millimeter wave radar and a medium, and belongs to the field of vehicle control, and the method comprises the steps: obtaining the driving direction of a vehicle, if the driving direction is a reversing direction, obtaining the real-time speed of the vehicle, and calculating the braking distance of the vehicle at the real-time speed; the steering angle of the vehicle is obtained, the driving route of the vehicle is judged based on the steering angle, if the driving route is of the first type, a first speed limiting area at the real-time speed is divided for the vehicle, and if the driving route is of the second type, a second speed limiting area at the real-time speed is divided for the vehicle; a millimeter-wave radar is arranged, parameter information of an obstacle within the detection range of the millimeter-wave radar is obtained, and the parameter information comprises a first distance between the vehicle and the obstacle; and whether the obstacle is in the speed limiting area or not is judged, and if yes, the vehicle is braked. According to the invention, the problem that the speed limiting area cannot be adjusted based on the change of the vehicle speed and the angle in the prior art can be solved.
本发明公开了一种基于毫米波雷达的倒车限速区域调节方法、系统及介质,属于车辆控制领域,包括:获取车辆的行驶方向,若行驶方向为倒车方向,则获取车辆的实时速度,计算车辆在实时速度下的制动距离;获取车辆的转向角,基于转向角判断车辆的行驶路线,若行驶路线为第一类型,为车辆划分在实时速度下的第一限速区域,若为第二类型,为车辆划分在实时速度下的第二限速区域;设置毫米波雷达,获取在毫米波雷达探测范围内的障碍物的参数信息,参数信息包括车辆与障碍物的第一距离;判断障碍物是否在限速区域内,若在限速区域内,对车辆进行制动处理。通过本发明可以解决现有技术中无法基于车速及角度的变化对限速区域进行调节的问题。
