Abstract

A device for detecting an installation error of satellite sensors on opposite sides of a vehicle is provided, which device detects the installation error based on a signal comparison between a door contact signal and a signal of one of the satellite (door acceleration) sensors during closing of a side door.

Claims

1-5. -5. (canceled)

6. A device for detecting an installation error of a first satellite sensor on a side of a vehicle corresponding to a first door, comprising:

a detection mechanism for detecting a first door contact signal indicating an imminent closing of the first door;

a detection mechanism for detecting a second door contact signal indicating an imminent closing of a second door on opposite side of the vehicle from the first door; and

a control unit for detecting the installation error of the at least one satellite sensor, wherein the installation error is detected based on a comparison between one of the first and second door contact signals and a signal of one of the first satellite sensor and a second satellite sensor on the side of the vehicle corresponding to the second door during closing of one of the first door and the second door.

7. The device as recited in claim 6, wherein the installation error is detected when the signal of one of the first satellite sensor and the second satellite sensor is not present within a predefined period of time after detecting of one of the first and second door contact signals.

8. The device as recited in claim 6, further comprising:

a memory, wherein information indicating the installation error is stored in the memory after the installation error has been detected.

9. The device as recited in claim 7, further comprising:

a memory, wherein information indicating the installation error is stored in the memory after the installation error has been detected.

10. The device as recited in claim 6, further comprising:

an alert mechanism for issuing an alert after the installation error has been detected.

11. The device as recited in claim 7, further comprising:

an alert mechanism for issuing an alert after the installation error has been detected.

12. The device as recited in claim 6, wherein the installation error is detected when the first door contact signal and the signal of the second satellite sensor are detected within the predefined period of time.
