Abstract
A heating device for a drive unit in a motor vehicle includes at least one heating element and at least one sensor by means of which a predetermined behavior of the vehicle user preceding the start of the drive unit can be detected. The sensor interacts with the heating element in such a manner that it is switched on when the sensor detects the predetermined behavior. The predetermined behavior may be one or more of the following: inserting an ignition key in an ignition lock of the motor vehicle; actuating a shifting, clutch or braking device of the motor vehicle; or a behavior through which an anti-theft device of the motor vehicle can be triggered.
