Method for self-diagnosis of a system
First Claim
Patent Images
1. A method for self-diagnosis of a system containing at least one base station having a transmit unit for transmitting signals and a receive unit for receiving the signals reflected by at least one associated reflector for detecting a respective seat occupancy, which comprises the steps of:
- deactivating a reflection function of the at least one reflector during the diagnostic method by a central control device connected to the at least one reflector and the base station;
transmitting, via the transmit unit of the base station, a modulated self-diagnosis signal having been modulated in a predetermined manner;
receiving the modulated self-diagnosis signal being a cross-talking modulated self-diagnosis signal in the receive unit of the base station; and
evaluating the cross-talking modulated self-diagnosis signal received for determining a self-diagnosis of operational integrity of the base station.

Abstract
In a method for self-diagnosis of a system for seat occupancy detection, in particular for self-diagnosis of a HOBBIT system, a self-diagnosis signal that has been modulated in a predetermined manner is transmitted by the transmit unit to the receive unit of the base station and analyzed, preferably with the reflectors deactivated. From the analysis it is possible to make deductions about the operational integrity of the base station.
