ABSTRACT:
A method and apparatus for monitoring driver fatigue in a vehicle having a steering control includes connecting a sensor with respect to the steering control and a controller with respect to the sensor. A steering input count signal and/or steering wheel rotation signal is provided from the sensor to the controller and an alarm is activated when the steering input count signal drops below a minimum level and/or the steering wheel rotation signal exceeds a maximum level. The alarm may trigger physical responses within the vehicle including audible, visual, engine management and/or similar responses.
