Pedestrian warning system and method for full electric vehicle

The invention provides a pedestrian warning system and method for a full electric vehicle. A controller is connected with a CAN bus, a radar probe and a sound production device, and after obstacle information and a CAN signal which are received by the controller meet preset conditions, the controller controls the sound production device to send out a warning prompt tone, wherein the obstacle information reflects that the radar probe recognizes an obstacle within a calibration range, and the CAN signal is transmitted through the CAN bus and reflects the current running state of the vehicle. The system provides a sound warning for pedestrians, and the problem that the radar detection technology is adopted in the prior art, no sound is sent out in the vehicle low-speed traveling process to remind the pedestrians that the vehicle is approaching, and consequently a collision accident happens is solved. 本发明提供了种纯电动车的行人警示系统和方法，通过控制器连接CAN总线、雷达探头以及发声装置，并在控制器接收到的反映雷达探头在标定范围内识别到有障碍物的障碍物信息和经CAN总线传输的反映车辆当前运行状态的CAN信号满足预设条件后
