The invention relates to an automobile electric seat anti-pinch control system and method based on millimeter wave radar. Comprising a backrest adjusting mechanism installed at the position of a seat backrest, a backrest driving motor for driving the backrest adjusting mechanism, a backrest motor Hall sensor installed in the backrest driving motor, a leg support adjusting mechanism installed at the position of a seat leg support, and a leg support driving motor for driving the leg support adjusting mechanism. The leg support motor Hall sensor, the leg support detection millimeter radar, the backrest detection millimeter radar and the seat control module are mounted in the leg support driving motor; the seat control module comprises a motor control module, a position judgment module, an anti-pinch detection module, an anti-pinch control module, a Hall pulse signal acquisition module and an mcu microcontroller; the method has the advantages that by actively detecting the obstacle encountered in the movement process of the seat, the clamping injury risk and the generated discomfort before the anti-clamping function of the seat is triggered are reduced, and meanwhile, the anti-clamping detection accuracy is greatly improved.
