ABSTRACT:
Methods and apparatus are provided for determining the duration a motor vehicle engine may operate while operator authorization is verified in response to an ignition request. In one embodiment the method includes the steps of decrementing a pre-authorization timer from a first predetermined time limit and a maximum authorization timer from a second predetermined time limit in response to the ignition request. Also upon receipt of the ignition request an authorization process is initiated. Decrementing of the pre-authorization timer is halted in response to active operation of the starter motor of the motor vehicle, and operation of the motor vehicle is inhibited if either the pre-authorization timer or the maximum authorization timer decrements to zero before completion of the authorization operation.
