Abstract
A start-stop device and a corresponding method brings about an automatic switch-off and/or switch-on operation of an automatically switched-off drive machine of a motor vehicle, in particular of a motor vehicle having an automatic transmission. The start-stop device has a switch-off logic, by way of which an automatic switch-off of the drive machine can be brought about in the case of a moving vehicle in accordance with a predefined switch-off operating strategy, and a switch-on logic, by way of which an automatic switch-on of the automatically switched-off drive machine can be brought about in accordance with a predefined switch-on operating strategy. The switch-off operating strategy and/or the switch-on operating strategy are/is configured in a manner which is based on wheel torque.
