Abstract

There is provided an occupant detection correction system including: a load detection section that detects load imparted to a vehicle seat and outputs a load signal representing the load; an occupant detection section that detects an occupant based on the load signal and is capable of resetting the load signal to a reference point based on a predetermined reset instruction; a tilt angle detection section that detects a predetermined tilt angle of a seatback; and a permitting section that permits execution of resetting the load signal to the reference point by the occupant detection section when the predetermined tilt angle is detected by the tilt angle detection section.

Claims

1. An occupant detection correction system comprising:

a load detection section that detects load imparted to a vehicle seat and outputs a load signal representing the load;

an occupant detection section that detects an occupant based on the load signal and is capable of resetting the load signal to a reference point based on a predetermined reset instruction;

a tilt angle detection section that detects a predetermined tilt angle of a seatback; and

a permitting section that permits execution of resetting the load signal to the reference point by the occupant detection section when the predetermined tilt angle is detected by the tilt angle detection section.

2. The occupant detection correction system of claim 1, further comprising:

a sliding position detection section that detects a sliding position of the vehicle seat; and

a headrest position detection section that detects a position of a headrest, wherein

the permitting section permits resetting to the reference point when the state of the vehicle seat is detected to be a specific state based the predetermined tilt angle being detected by the tilt angle detection section, and the detection results of the sliding position detection section and the headrest position detection section.

3. The occupant detection correction system of claim 1, wherein the permitting section is provided separately to a vehicle, and permits execution of resetting to the reference point by outputting a reset instruction to the occupant detection section when the predetermined tilt angle is by the tilt angle detection section.

4. The occupant detection correction system of claim 1, wherein the load detection section is provided at two locations at the vehicle rear-side of the seat cushion and detects load imparted to the rear side of the vehicle seat.
