System and method for determining whether a vehicle operator has an impaired cognitive state
First Claim
1. A method for determining whether an operator of a vehicle is intoxicated, comprising:
- generating a first signal indicative of a first location of the vehicle at a first time, utilizing a global positioning system device, when a vehicle ignition switch is in a predetermined operating position;
determining a location classification associated with the first location of the vehicle based on the first signal, utilizing a controller;
determining whether the operator is intoxicated based on the location classification and a time duration value indicative of the vehicle being at the first location, utilizing the controller; and
generating a second signal when the operator is intoxicated, utilizing the controller.

Abstract
A system and a method for determining whether an operator of a vehicle has an impaired cognitive state are provided. The method includes determining an intoxication indication value indicative of whether the operator is intoxicated, utilizing a controller. The method further includes determining a drowsiness indication value indicative of whether the operator is drowsy, utilizing the controller. The method further includes determining a fatigue indication value indicative of whether the operator is fatigued, utilizing the controller. The method further includes determining a cognitively impaired indication value based on at least one of the intoxication indication value, the drowsiness indication value, and the fatigue indication value. The method further includes generating a signal indicating that the operator is cognitively impaired when the cognitively impaired indication value is greater than a threshold cognitively impaired indication value, utilizing the controller.
