1. A drive device configured to adjust a vehicle assembly, the drive device comprising:
an electromotive adjustment drive configured to adjust the vehicle assembly; and
a control device configured to control the electromotive adjustment drive and command the electromotive adjustment drive to operate in a holding mode, in which the electromotive adjustment drive is actuated to hold the vehicle assembly,
wherein the control device is further configured to regulate a current of the electromotive adjustment drive and determine a correcting variable for regulating the current of the electromotive adjustment drive, in the holding mode, with reference to a specified setpoint value, wherein the control device is further configured to determine the correcting variable as a voltage value and to set a motor voltage with reference to the voltage value by using a pulse width modulation, and
evaluate a change of the correcting variable to detect an adjustment request to adjust the vehicle assembly;
wherein the control device is further configured to monitor the correcting variable, to identify the adjustment request based on a comparison of the correcting variable and threshold value and to terminate the holding mode in case the adjustment request is identified.
