Door courtesy switch abnormality detection apparatus and method
First Claim
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.

Abstract
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.

6. An on-vehicle system for use with a vehicle having a function of detecting an abnormality in a door courtesy switch, comprising:
-
the door courtesy switch; an antenna having a detection area thereof within a cabin of the vehicle; and an electronic control apparatus including; an unlock detector configured to detect a door unlock operation; a door open/close operation detector configured to detect door open and close operations from the door courtesy switch; a smart electronic control unit configured to determine whether the electronic key exists in a cabin of a vehicle based on a status of a response signal transmitted from the electronic key, said response signal responding to a signal transmitted from the antenna; and a body electronic control unit configured to generate information identifying a presence of an abnormality in the door courtesy switch; wherein the smart electronic control unit performs the determination in response to an ON/OFF signal of the door courtesy switch being not inverted after the door unlock operation is detected by the unlock detector, and the smart electronic control unit and the body electronic control unit;
(i) generate the information representing 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 the 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. - View Dependent Claims (7, 8)

9. A door courtesy switch abnormality detection method for use in an on-vehicle system having a door courtesy switch and in which a door unlocked status is determined based on a wireless signal transmitted from an electronic key, said method comprising:
-
an unlock detecting step of detecting a door unlock operation; a door open operation detecting step of detecting a door open operation based on an ON/OFF signal from the door courtesy switch if the door unlock operation is detected in the unlock detecting step; a determining step of determining whether the electronic key exists in a cabin of a vehicle based on a status of a radio wave transmitted from the electronic key in response to the door open operation being not detected in the door open operation detecting step; and an information generating step of generating information identifying;
(i) a presence of an abnormality in the door courtesy switch when it is determined in the determining step that the electronic key exists in the cabin of the vehicle by an antenna having a detection area thereof within the cabin of the vehicle and a door open operation after the door unlock operation is not detected, or (ii) an absence 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.

10. A door courtesy switch abnormality detection apparatus for use in a vehicle having a door courtesy switch, an antenna having a detection area thereof within a cabin of the vehicle, and in which a door unlocked status is determined based on a wireless signal transmitted from an electronic key, the door courtesy switch abnormality detection apparatus comprising:
a processor programmed to; detect a door unlock operation; detect door open and close operations from the door courtesy switch; detect a presence of the electronic key in a cabin of the vehicle; and generate information identifying;
(i) a presence of an abnormality in the door courtesy switch when the electronic key is detected in the cabin of the vehicle by the antenna, in response to an ON/OFF signal of the door courtesy switch being not inverted after a door unlock operation is detected such that a door open operation after the door unlock operation is not detected, or (ii) an absence 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.
