  • Two-step power door locking system and method of operation
    Patent number: 5619075
    Abstract: An automotive locking system for an automotive vehicle has a latch with a locked and unlocked position, a switch having a first state and a second state and a timer. A controller is connected to the switch, the latch and the timer. The controller positions the latch of a door in the unlocked position if the duration the switch is in the first and second states corresponds to a valid switch signal rather than electrical noise or a shorted switch. The system may also control unlatching all the doors if the switch changes between the first and second states for predetermined durations of each state.
