Abstract: A pedal with anti-collision detection is installed on the rear of a vehicle. The pedal includes a pedal body and a radar device, with an insertion portion extending from the rear lateral side of the pedal body. Arc ribs are arranged from a rear lateral side of the pedal body toward a front lateral side of the pedal body at intervals, and straight ribs extend from the rear lateral side toward the front lateral side in a radial arrangement. The arc ribs and the straight ribs are interlaced, forming reinforcement spaces therebetween. An installation space is formed on an inner side of the front lateral side toward the rear lateral side for receiving the radar device. Each reinforcement space contains a reinforcement structure, thereby strengthening the structural strength of the pedal for protecting the radar device.
