The active collision avoidance system based on a rotary scanning distance measuring sensor includes a microprocessor, a vehicle information acquisition unit, a deceleration braking unit and a ranging sensor. The active collision avoidance system uses a single rotation scan Distance measuring sensor instead of multiple distance measuring sensors in the prior art, rotating scanning distance measuring sensor measures the distance and angle of the obstacles around the vehicle with the scanning mode, and combines the vehicle driving data acquired by the vehicle information acquiring unit with the micro processing According to the vehicle driving situation, the deceleration braking unit automatically controls the deceleration of the vehicle brake, which can effectively prevent the occurrence of a collision accident, completely eliminating the problem of blind spot in the detection point, complicated wiring in installation, high cost and the like, and the ranging is more accurate and reliable, greatly improving the driving of the vehicle Security.
