The invention discloses an active and passive fusion type truck rear protection system and method, and belongs to the technical field of collision protection. The active and passive fusion type truck rear protection system comprises a control system, a radar system, a camera, a road slope monitoring device, a display device, a safety airbag, a servo motor and a rear protection device; based on non-contact sensing systems such as a laser radar or a millimeter wave radar and a camera of an advanced driver assistance system (ADAS), the type, height, longitudinal relative position and the like of a rear passenger car are accurately recognized, and an algorithm strategy is designed to control a servo motor to quickly adjust the height of a rear protection device so as to maximize the protection area. And the passenger car rear-end collision working conditions of 100% overlapping, 50% overlapping and 30% overlapping are met. Meanwhile, the collision energy absorption capacity and the protection effect of the rear passenger car are improved to the maximum extent in the modes that a collision composite material serves as a structural reinforcing piece, an anti-collision net curtain covers structural gaps, and safety air bags are additionally arranged. And the rear part of the truck is integrated with visual sense, sound sense and warning functions.
