The invention discloses a novel vehicle seat pressure sensor. The vehicle seat pressure sensor comprises a cushion (1) and a framework (2), wherein a pressure measuring plate (3) is arranged between the cushion (1) and the framework (2); pressure sensing sheet sensors (31) are uniformly distributed on the pressure measuring plate (3); bulges (12) are arranged on the lower surface of a bottom plate (11) of the cushion; grooves (34) are formed in the upper surface of the pressure measuring plate (3); the grooves (34) and the bulges (12) are adaptive with sensitive sheets of the pressure sensing sheet sensors (31) in shape, size, position and number; when in use, the bulges (12) stretch into the grooves and are clung to the sensitive sheets; the pressure sensing sheet sensors (31) cover the bottom plate (11). After the structure is adopted, the pressure of a passenger to a seat can be correctly and reliably measured, and a phenomenon that a measurement value is changed due to the changes of a seated stress point of the passenger is avoided.
