1. A system for monitoring driver fatigue and inattention in a vehicle having a steering control, the system comprising:
- an ABS sensor connected with respect to the steering control;
a controller connected with respect to the ABS, the ABS sensor providing a steering input count signal to the controller, wherein the controller comprises a programmable logic controller connected with the ABS sensor, the programmable logic controller using ladder logic to evaluate steering input; and
an alarm connected with respect to the controller, the alarm activated when the steering input count signal drops below a minimum level.

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 is provided from the sensor to the controller and an alarm is activated when the steering input count signal drops below a minimum level. The alarm may trigger physical responses within the vehicle including audible, visual, engine management and/or similar responses.
