Immobilizer system for a motor vehicle
First Claim
1. An immobilizer system for a motor vehicle comprising:
- a detector configured to measure a level of an impairing substance in a body of a driver;
an interlock configured to alternatively allow and prevent operation of the vehicle; and
a controller programmed toduring a pre-programmed time period, require a negative test result from the detector before allowing operation of the vehicle, andoutside of the pre-programmed time period, allow operation of the vehicle without requiring use of the detector.

Abstract
An immobilizer system for a motor vehicle having an starter mechanism and a substance detector for detecting impairing drugs/substances in a driver'"'"'s bode, the allowing the vehicle to be started/operated only when the substance detector delivers a result which is below a limit value. An electronic controller of the immobilizer system is programmed by the driver to pre-specify which restrictions the starter mechanism is subject to if the substance detector delivers a positive test result (above a limit level). The immobilizer may be programmed to either a) prevent operation of the vehicle, or b) allow operation but present a notification to the driver. The driver may set a future time interval during which a selection of option a) cannot be changed by the driver.

11. A method of operating an immobilizer system for a vehicle comprising:
-
via a controller, providing a driver with an option to select between, upon a positive test for an impairing substance in the driver'"'"'s body, a) preventing vehicle operation, and b) allowing vehicle operation and generating a notification indicating the positive test results, and via the controller, preventing the driver from changing the selection of option a) during a time period designated by the driver. - View Dependent Claims (12, 13, 14, 15, 16)
