METHOD FOR MONITORING A DOOR CONTACT SWITCH OF A DRIVER' S DOOR OF A MOTOR VEHICLE
First Claim
1. :
- A method for monitoring a door contact switch of a driver'"'"'s door of a motor vehicle locked in an idle state, the method comprising;
a) detecting an unlocking of the driver'"'"'s door of the motor vehicle,b) detecting whether a change in a door contact signal of the door contact switch takes place after the unlocking of the driver'"'"'s door,c) initializing a plausibility counter (P) if a change in the door contact signal has been detected, otherwised) detecting whether a drive unit of the motor vehicle is activated, ande) establishing a “
door contact implausible”
state and incrementing the plausibility counter (P) if the activation of the drive unit has been detected in step d).

Abstract
A method for monitoring a door contact switch of a driver'"'"'s door of a motor vehicle locked in an idle state includes detecting an unlocking of the driver'"'"'s door of the motor vehicle, and detecting whether a change in a door contact signal of the door contact switch takes place after the unlocking of the driver'"'"'s door. If a change in the door contact signal has been detected, a plausibility counter is initialized, otherwise the method includes detecting whether a drive unit of the motor vehicle is activated. A “door contact implausible” state is established and the plausibility counter (P) is incremented if the activation of the drive unit has been detected in step d).

8. :
- A method for monitoring a door contact switch of a driver'"'"'s door of a motor vehicle based on an idle state in which a drive unit of the motor vehicle is deactivated and the driver'"'"'s door is either unlocked or internally locked, the method comprising;
a) detecting an activation of a drive unit of the motor vehicle, b) continuing the method with method step a) if the drive unit of the motor vehicle has not been activated, otherwise c) detecting whether a change in a door contact signal of a door contact switch has taken place before the switch to the idle state, and d) initializing a plausibility counter (P) if a change in the door contact signal has been detected, otherwise e) establishing a “
door contact implausible”
state and incrementing the plausibility counter (P). - View Dependent Claims (9, 10, 11, 12, 13)
