Impairment evaluation system
First Claim
1. A system for use in a motor vehicle, the system configured to administer an impairment evaluation, the system comprising:
- a database;
a plurality of impairment events stored in the database, wherein each of the plurality of impairment events includes a geographic location of a place and a time period;
an electronic control unit, the electronic control unit having a processor configured to process and read a computer executable instruction that, when executed, cause the electronic control unit to determine a sober driver profile, wherein the sober driver profile is determined during a predetermined period of time when any one of the plurality of impairment events is not detected, wherein a braking habit, speed and turning characteristic of the driver are recorded over the predetermined period of time to determine the sober driver profile; and
a sensor assembly, the sensor assembly detecting a location and a current driving operation of the motor vehicle after a motor vehicle stop, the sensor assembly including a speedometer, an accelerometer, a steering wheel angle sensor and a brake pad sensor detecting speed, turning and braking force of the motor vehicle;
wherein the electronic control unit also receives the current driving operation of the vehicle from the sensor assembly, compares the current driving operation of the vehicle with the sober driver profile after the motor vehicle stop, and identifies the location of the motor vehicle stop as a new impairment event and permanently stores the new impairment event in the database as one of the plurality of impairment events when the current driving operation of the vehicle deviates from the sober driver profile a predetermined amount, wherein the electronic control unit further associates the location of the motor vehicle stop within the new impairment event, and wherein every time the motor vehicle subsequently makes a stop at the location associated with the new impairment event, the electronic control unit administers a challenge to the driver after the impairment event so as to determine if the driver is impaired, wherein the electronic control unit renders the vehicle inoperable when the driver fails the challenge.

Abstract
A system configured to administer an impairment evaluation when a driver has been identified as attending an impairment event is provided. The system includes a driver profile unit configured to determine a sober driver profile. A sensor unit detects the location and operation of the motor vehicle after a motor vehicle stop. An impairment event unit receives the information regarding the operation of the vehicle from the sensor unit and compares the operation of the vehicle with the sober driver profile after the motor vehicle stop. The drinking unit identifying the motor vehicle stop as an impairment event when the operation of the vehicle deviates from the sober driver profile a predetermined amount. A challenge is administered to the driver after the impairment event so as to determine if the driver is impaired. The vehicle is rendered inoperable when the driver fails the challenge.
