Abstract
Methods and systems for monitoring a switch included in a vehicle. One method includes a method of monitoring a switch included in a vehicle. The method includes obtaining a current vehicle speed, and dynamically, by a controller, generating a duration for detecting a stuck state of the switch based on at least the current vehicle speed, detecting, by the controller, a duration of a high signal received from the switch. The method also includes comparing, by the controller, the duration of the high signal to the generated duration, and detecting, by the controller a stuck state of the switch when the duration of the high signal satisfies the generated duration.
