Abstract

In a process for determining the amount of time elapsed between stopping a motor vehicle engine and restarting the engine, when the engine is restarted, the time information representing the time when the engine was stopped is subtracted from the time information representing the time when the engine was restarted. The time information representing the respective times is obtained from an on-board clock that serves to display the time in the motor vehicle.
