An automobile includes a main body, and an infrared detecting unit on the front portion of the main body. The infrared detecting unit includes an infrared emitter connected to a motor, and an infrared receiver. An anti-collision method includes controlling the motor to rotate to rotate the infrared emitter. Controlling the rotating infrared emitter at each rotated position to emit infrared lights with an effective projection range L which form an illuminating trajectory spaced from the front portion by a distance S. Calculating a height of a protruding portion on the road surface according to the effective projection range L, the distance S, and the distance between the infrared detecting unit and the road surface H, if the infrared receiver receives the reflected infrared lights reflected by the protruding portion. Actions are preformed to protect the automobile if the calculated height is greater than a preset value.
