Abstract

A vehicular passenger detection system includes a load detection device configured to detect a load that acts upon a seat that is installed upon a vehicle, a passenger seating detection device configured to determine whether or not a passenger is seated upon the seat, in accordance with a result of a detection of the load detection device, and a fault recording device configured to record an information of a fault that has occurred upon either the load detection device or the passenger seating detection device. The fault recording device includes a fault determination device configured to determine whether or not the information of the fault is information of a fault whereupon a repair is required.

Claims

1. A vehicular passenger detection system, comprising:

a load detection device configured to detect a load that acts upon a seat that is installed upon a vehicle;

a passenger seating detection device configured to determine whether or not an occupant is seated upon the seat, in accordance with a result of a detection of the load detection device; and

a fault recording device configured to record information of a fault that has occurred upon either the load detection device or the passenger seating detection device;

wherein

the fault recording device includes a fault determination device configured to determine whether or not the information of the fault is information of a fault whereupon a repair is required.

2. The vehicular passenger detection system according to claim 1, wherein:

the fault determination device includes a fault recording unit configured to record a fault and a baseline value compensation recording unit configured to record information of a fault that relates to a repair.

3. The vehicular passenger detection system according to claim 2, wherein:

the fault recording unit includes a fault recording unit table configured to record information of a fault, such as a location or a description of the fault.

4. The vehicular passenger detection system according to claim 2, wherein the baseline value compensation recording unit includes a baseline value compensation recording unit table configured to record information of a fault that relates to a repair that is performed immediately prior to performing a compensation of a baseline value compensation of the load detection device when a maintenance or repair is performed, as information of a compensation thereof.
