The invention relates to an automotive seat pressure sensor which is connected with a vehicle control unit. The sensor comprises a pressure sensing module, resistors, a plastic packaging block, a supporting piece, a harness, an elastic material and an abrasion-resistant separation layer. The pressure sensing module, the resistors, the harness, a connector and the vehicle control unit are sequentially connected; the resistors are arranged in the plastic packaging block; the elastic material is fixed on the supporting piece; the pressure sensing module and the abrasion-resistant separation layer are detachably connected with the supporting piece through the plastic packaging block, and the abrasion-resistant separation layer, the pressure sensing module and the elastic material are sequentially arranged from top to bottom; the connector and the supporting piece are detachably connected. The vehicle control unit judges the current occupancy state of a seat according to electric signals detected by the seat pressure sensor. Compared with the prior art, identification signals for circuit break, short circuit faults and the like are added to a control system; meanwhile, the automotive seat pressure sensor has the advantages that comfortableness and sensitivity are improved, universality is high, the structure is simple, and the automotive seat pressure sensor is convenient to use.
