Method and System for Detecting Door State and Door Sensor Failures
First Claim
1. In a vehicle including a door, a door latch sensor, a door lock sensor, a shift-by-wire transmission and a controller, a method for performing a controller feature comprising:
- determining failure in the door latch sensor including receiving a door state signal from the door latch sensor, receiving a door lock signal from the door lock sensor, and determining from the door state signal and the door lock signal if the door latch sensor is faulty; and
performing the controller feature based on the door state signal when the door latch sensor is not faulty and based on the door lock signal and not the door state signal when the door latch sensor is faulty.

Abstract
A system includes a controller that executes a method for determining failure of the door latch sensor using both the door latch sensor and a door lock sensor. If the door latch sensor is faulty, the controller adjusts an automatic feature of the vehicle based on a door lock signal instead of a door state signal. The controller is also configured to mark the door latch signal as faulty if the door latch system is not functioning properly by using a fault counter that tracks the door lock sensor.

9. A system performing a controller feature comprising:
-
a vehicle including, a shift-by-wire transmission, a controller and a door having a door latch and a door lock; a door latch sensor for sending a door state signal indicating if the door is open or closed; a door lock sensor for sending a door lock signal indicating if the door is locked or unlocked; and a controller for determining failure in the door latch sensor including receiving the door state signal from the door latch sensor, receiving a door lock signal from the door lock sensor, and determining from the door state signal and the door lock signal if the door latch sensor is faulty; and
performing the controller feature based on the door state signal when the door latch sensor is not faulty and based on the door lock signal and not the door state signal when the door latch sensor is faulty. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
