摘要：
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.
