Method and apparatus for detecting projected impairment
First Claim
1. A method for detecting impairment of a vehicle operator, the method comprising:
- detecting a first impairment level;
in response to determining that the first impairment level is greater than a first impairment threshold, determining whether the first impairment level is greater than a second impairment threshold;
in response to determining that the first impairment level is greater than the second impairment threshold, inhibiting a vehicle operation;
in response to determining that the first impairment level is less than the second impairment threshold, detect a second impairment level;
based on the first impairment level and the second impairment level, determine a third impairment level at a future time; and
in response to determining that the third impairment level is greater than the second impairment threshold, inhibiting the vehicle operation,wherein the first, second, and third impairment levels are levels corresponding to a presence of a substance in a subject that indicates the subject has a diminished cognitive or physical ability caused by the substances, andwherein the first impairment threshold and the second impairment threshold are preset thresholds corresponding to detectable substances that cause the diminished cognitive or physical ability.

Abstract
A method and apparatus for detecting impairment of a vehicle operator are provided. The method includes detecting a first impairment level at a first time; detecting a second impairment level at a second time after the first time; based on the detected first impairment level and the detected second impairment level, determining a third impairment level at a third time after the second time; and inhibiting vehicle operation in response to determining that the third impairment level is greater than an impairment threshold. The apparatus and method may be used in a vehicle or other apparatus to prevent vehicle operator from operating the vehicle while impaired or prior to becoming impaired.

11. An apparatus for detecting impairment of a vehicle operator, the apparatus comprising:
-
at least one memory comprising computer executable instructions; and at least one processor configured to read and execute the computer executable instructions, the computer executable instructions causing the at least one processor to; detect a first impairment level at a first time; detect a second impairment level at a second time after the first time; based on the detected first impairment level and the detected second impairment level, determine a third impairment level at a third time after the second time; and inhibit vehicle operation in response to determining that the third impairment level is greater than an impairment threshold, wherein the first, second, and third impairment levels are levels corresponding to a presence of a substance in a subject that indicates the subject has a diminished cognitive or physical ability caused by the substances, and wherein the first impairment threshold and the second impairment threshold are preset thresholds corresponding to detectable substances that cause the diminished cognitive or physical ability. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A non-transitory computer readable medium comprising computer executable instructions executable by a processor to perform a method for detecting impairment of a vehicle operator, the method comprising:
-
receiving impairment information, the impairment information including a plurality of impairment levels measured at a plurality of times, respectively; based on the received impairment information, selecting an impairment projection model from among a plurality of impairment projection models; determining a projected impairment level based on the impairment information and the selected impairment projection model; and inhibiting vehicle operation in response to determining that the projected impairment level is greater than an impairment threshold, wherein the plurality of impairment levels are levels corresponding to a presence of substance in a subject that indicates the subject has a diminished cognitive or physical ability caused by the substances, and wherein the impairment threshold corresponds to a detectable substance that cause the diminished cognitive or physical ability. - View Dependent Claims (19, 20)
