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.
Claims18
A system for monitoring a switch included in a vehicle, the system comprising:
- a controller configured to:
- obtain at least one current driving condition,
- dynamically generate at least one parameter for detecting a predetermined state of the switch based on the at least one current driving condition,
- receive a signal from the switch,
- compare the signal to the at least one parameter, and
- determine a state of the switch when the signal satisfies the at least one parameter.
A method of monitoring a switch included in a vehicle, the method comprising:
- obtaining a current vehicle speed;
- 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;
- 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.
