The invention discloses a passenger protection system based on a human body injury potential field and a control method, the passenger protection system comprises a passenger protection early warning module, the passenger protection early warning module comprises a GPS, a vehicle speed measuring instrument, a laser radar, a first early warning unit, a static obstacle collision risk potential field calculation unit, a dynamic obstacle risk potential field calculation unit and a second early warning unit; the passenger protection path planning module comprises a virtual time domain human body injury prediction unit, a human body injury potential field calculation unit and a discrete path point prediction unit; the passenger protection control module comprises a path fitting unit and an MPC controller. According to the method, on the basis of human body injury prediction, when the vehicle is about to be subjected to inevitable collision, the protection route with the minimum injury is planned in a self-adaptive mode, and therefore the safety of passengers is protected to the maximum degree in a traffic accident; therefore, the casualties of passengers in traffic accidents are effectively reduced; the method is suitable for various complex road traffic scenes, and has the advantages of simple structure and high robustness.
