First Claim
Patent Images
1. A vehicle door latch control system, comprising:
- a latch mechanism motor;
a bus;
at least one occupant-operable regulator;
a door controller connected to the latch mechanism motor, the bus and said at least one regulator, the door controller containing door controller logic that detects a fault in the bus and that assigns control of the latch mechanism motor to one of said regulators upon detection of the fault.

Abstract
A vehicle door controller connected to various door components and to a bus is programmed to reassign at least one vehicle occupant-operable regulator to actuate a latch mechanism motor if a fault is detected in the bus. The regulator and door controller may be used to perform security locking even when the bus is unable to carry signals to the latch mechanism.

8. A door controller for a vehicle door, comprising:
-
a first terminal to connect the door controller to a bus;
a second terminal to connect the door controller to a latch mechanism motor;
at least one regulator terminal to connect the door controller to at least one occupant-operable regulator;
detection logic that detects a fault in a bus connected to the bus connection terminal; and
security locking logic that detects operation of at least one occupant-operable regulator and issues a security locking command to the latch mechanism motor to perform security locking of a door latch mechanism if the detection logic detects the fault in the bus.

9. A method for controlling a vehicle door latch system mechanism having a latch mechanism, a bus, and at least one occupant-operable regulator, the method comprising:
-
detecting a fault in the bus;
assigning control of the latch mechanism to one of said regulators upon detection of the fault; and
operating the latch mechanism when the regulator is actuated. - View Dependent Claims (10, 11, 12, 13, 14, 15)
