The invention relates to a low-speed driving turning auxiliary method based on an ultrasonic radar. Obstacles in front of and beside a vehicle are scanned in real time through an ultrasonic radar sensor; a turning radius range, in which the vehicle can make turning safely without any collision in the low-speed driving process. of the vehicle can be calculated by combining vehicle real-time position information calculated by the system; and a turning radius is selected from the turning radius range to serve as a guiding turning radius and a turning starting point corresponding to the guiding turning radius is calculated. When the vehicle reaches the turning starting point, a driver is reminded to turn, so that the safety of the vehicle during turning is improved.
本发明涉及一种基于超声波雷达的低速行车转弯辅助方法,其通过超声波雷达传感器实时扫描车辆前方及侧方障碍物,结合系统计算的车辆实时位置信息,计算出车辆在低速行驶过程中可以安全无碰撞地实现转弯的转弯半径范围,并从转弯半径范围内选取一转弯半径作为引导转弯半径,计算与引导转弯半径对应的转向起点,当车辆到达该转向起点时提醒驾驶员可以进行转弯,从而提高车辆转弯时的安全性。
