The invention relates to a steering wheel follow-up laser radar which comprises a laser radar body, a transmission mechanism driving the laser radar body to rotate and a control system controlling the transmission mechanism. The laser radar is rotationally connected to the bumper support. The transmission mechanism comprises a motor and a connecting rod with one end engaged with an output shaft of the motor, and the other end of the connecting rod is hinged to the laser radar. The control system comprises a controller and a steering angle sensor, the steering angle sensor is used for collecting steering wheel steering angle information and transmitting the information to the controller, and the controller controls output of motor torque. According to the steering wheel follow-up laser radar and the follow-up control method thereof provided by the invention, the laser radar can realize follow-up steering of the laser radar following the turning direction of a vehicle in a curve adaptive cruise process, so that the accuracy of target identification is improved, the laser radar is safe and reliable, and the problems of response delay and poor stability of the existing laser radar are solved. And a target object of an adjacent lane is wrongly identified to cause emergency braking.

    本发明涉及一种方向盘随动激光雷达,包括激光雷达、带动激光雷达转动的传动机构、以及控制传动机构的控制系统。激光雷达可转动的连接在保险杠支架上;传动机构包括电机,以及一端与电机的输出轴啮合连接的连杆,连杆的另一端与激光雷达铰接;控制系统包括控制器和转角传感器,转角传感器用于采集方向盘转角信息并传递给控制器,控制器控制电机扭矩的输出。本发明提供的一种方向盘随动激光雷达及其随动控制方法,该激光雷达可以实现弯道自适应巡航过程中,激光雷达跟随车辆转弯方向的随动转向,提高了目标识别的准确性,安全可靠,解决了现有激光雷达存在的反应迟滞,误识别相邻车道的目标物,引发紧急刹车问题。
