Abstract
A steering column may include a first adjustment drive for adjustments in a length adjustment direction and a second adjustment drive for adjustments in a height adjustment direction. The adjustment drives each have a drive motor. A joint control unit for the drive motors comprises three half bridges arranged in parallel and connected between two voltage potentials. Each half bridge has a high-side switch and a low-side switch connected in series via a connection point. The connection point of the first half bridge is electrically conductively connected to a first connection of a first drive motor. The connection point of a second half bridge is electrically conductively connected to a second connection of the first drive motor and to a first connection of the second drive motor. The connection point of a third half bridge is electrically conductively connected to a second connection of the second drive motor.
