Door courtesy switch abnormality detection apparatus and method

摘要

A door courtesy switch abnormality detection apparatus used in an on-vehicle system in which a door unlocked status is formed based on a wireless signal transmitted from an electronic key is disclosed. The apparatus is configured to generate information representing an abnormality in the door courtesy switch, if the electronic key in a cabin of a vehicle is detected by a antenna having the detection area thereof within the cabin of the vehicle in a situation where an ON/OFF signal of the door courtesy switch is not inverted after the door unlock operation is detected.

主权项

1. A door courtesy switch abnormality detection apparatus for use in an on-vehicle system having a door courtesy switch in which a door unlocked status is determined based on a wireless signal transmitted from an electronic key, said apparatus comprising:
an unlock detector configured to detect a door unlock operation; a door open/close operation detector configured to detect door open and close operations based on an ON/OFF signal from the door courtesy switch; a smart electronic control unit and a body electronic control unit configured to generate information identifying a presence of an abnormality in the door courtesy switch; and the smart electronic control unit being configured to determine whether the electronic key exists in a cabin of a vehicle based on a status of a radio wave transmitted from the electronic key under a situation where the door open operation is not detected by the door open/close operation detector, if the door unlock operation is detected by the unlock detector, wherein:
the smart electronic control unit and the body electronic control unit: (i) generate the information identifying the presence of the abnormality in the door courtesy switch when it is determined that the electronic key exists in the cabin of the vehicle and a door open operation after a door unlock operation is not detected by the door open/close operation detector, and (ii) not generate the information identifying the presence of the abnormality in the door courtesy switch when it is determined that the electronic key exists in the cabin of the vehicle and the door open operation is detected after a door unlock operation by the door open/close operation detector.
