摘要:
A method (60) for adjusting the zero point of a vehicle seat weight sensing system (10) includes the step of determining a zero point error (64) of the seat weight sensing system. The method (60) also includes the step of adjusting the zero point error (68) in response to determining that the zero point error was influenced by an object on the vehicle seat.
摘要:
An apparatus (10) is used in a vehicle having a seat (2) for a vehicle occupant and a vehicle floor pan (4) for supporting the vehicle seat (2). The apparatus (10) includes a vehicle seat frame (20), a bracket (30), a spring element (240, 340 or 340, 350), a lever (90), and a sensor (992). The spring element (240, 340 or 340, 350) compresses to allow the vehicle seat frame (20) to move vertically when the load of the vehicle occupant acts on the vehicle seat (2). The lever (90) has a first end portion (100) and a second end portion (110) opposite the first end portion (100). The first end portion (100) is movable with the vehicle seat frame (20). The second end portion (110) is movable with the vehicle seat frame (20). The lever (90) has a middle portion (120) interposed between the first end portion (100) and the second end portion (110). The lever (90) bends as the vehicle seat frame (20) moves vertically relative to the bracket (30). The sensor (992) detects movement of the middle portion (120) of the lever (90) and provides an output signal indicative of the amount of movement of the middle portion (120) of the lever (90).
