The invention discloses an unmanned bus drive-by-wire chassis and an automatic driving system thereof, and the unmanned bus drive-by-wire chassis comprises a chassis main body. According to the invention, image and 3D laser front fusion perception is used for environment detection of pedestrians, lane lines and the like, so that correct understanding and corresponding decision making of the self-driving automobile on the surrounding environment of the automobile body are ensured. The identification of the road red street lamp depends on a V2X intelligent network connection technology on the basis of 5G communication, a signal transmitter is installed on a traffic light to continuously transmit state information of the traffic light to the periphery, and an automatic driving automobile judges the state of the traffic light by receiving a signal transmitted by the signal transmitter. The MPC trajectory tracking is adopted, so that the vehicle can run along the predetermined trajectory, and the algorithm has excellent performance, shows stable and accurate tracking capability for the tracked trajectory, and has enough real-time performance at the same time.

    本发明公开了一种无人巴士线控底盘及其自动驾驶系统,一种无人巴士线控底盘,包括底盘主体。本申请中,图像及3D激光前融合感知,用于进行行人和车道线等环境检测确保了自动驾驶汽车对车身周围环境的正确理解和对应决策。对道路红路灯的识别依靠5G通信基础上的V2X智能网联技术,该技术通过在红绿灯上安装信号发射器来不断地向四周发射红绿灯的状态信息,自动驾驶汽车通过接收信号发射器发出的信号来判断红绿灯的状态,采用MPC轨迹跟踪能够使车辆沿着预定的轨迹行驶,该算法具有较为优异的性能,对所跟踪的轨迹表现出了稳定和精确的跟踪能力,同时具有足够的实时性。
