ABSTRACT:
Method and apparatus for disabling an automobile powered by an engine utilizing an automatic transmission with a gear selector movable between non-drive and drive positions. After the engine is started up with the gear selector in a non-drive position, the movement of the latter into a drive position initiates a timer to deliver a signal for a predetermined period of time such as 15 seconds. That signal is employed to disable the engine within the vehicle if during that period an acceleration or throttle measuring device indicates that excessive acceleration is occurring or that a seat sensor device indicates that the driver is not present. Acceleration is measured by sensing intake manifold pressure or throttle position.
