Pedestrian warning device

The utility model provides a pedestrian warning device, belongs to the technical field of automobiles, and solves the problems of complex structure and poor universality of the pedestrian warning devices in the prior art. The pedestrian warning device comprises an infrared sensor for detecting infrared signals of living bodies and a radar for detecting distance signals; the infrared sensor and the radar are connected with an electronic control unit (ECU) of the whole automobile respectively; and the ECU of the whole automobile is further connected with a prompt unit used for sending warning signals, used for receiving the infrared signals sent by the infrared sensor, controls the radar to detect the distance signals, receives the distance signals for analytical processing, and outputs control signals to the prompt unit. The device can identify pedestrians and warn a driver within relevant distance, and is simple in structure and high in practicability.
