First Claim
1. A method of controlling an automatic switch-off and switch-on procedure of a drive unit in a motor vehicle equipped with a start-stop device, the method comprising the acts of:
- automatically switching-off the drive unit of the motor vehicle if predefined switch-off conditions have been met;
automatically switching-on an automatically switched-off drive unit if at least one driver-side switch-on request occurs, wherein the driver-side switch request is a request to automatically switch on the switched-off drive unit that is provided by an operator of the motor vehicle; and
if a system-side switch-on request occurs while the drive unit was automatically switched-off, at least temporarily suppressing the automatic switch-on procedure if a delay condition exists, wherein the system-side switch request is a request to automatically switch on the switched-off drive unit that is provided by a system of the motor vehicle without input from the operator.

Abstract
A method of controlling an automatic switch-off and switch-on procedure of a drive unit in a motor vehicle via a start-stop device is provided, by which, when the motor vehicle stops, the drive unit is automatically switched off if predefined switch-off conditions have been met, and by which an automatically switched-off drive unit is automatically switched on if at least one driver-side or system-side switch-on request is made. When a system-side switch-on request takes place, the automatic switch-on procedure will be suppressed at least temporarily if a delay condition exists.
