System and method for monitoring driver fatigue
First Claim
1. A system for monitoring driver fatigue and inattention in a vehicle having a steering control, the system comprising:
- a sensor connected with respect to the steering control;
a controller connected with respect to the sensor, the sensor providing a steering input count signal to the controller;
an alarm connected with respect to the controller, the alarm activated when the steering input activity level exceeds a predetermined threshold.

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.
