Abstract (en)
[origin: WO2020099362A1] The invention relates to a steering column (1) for a steering system of a motor vehicle, comprising a first adjustment drive (2) for adjusting the steering column in a longitudinal adjustment direction (X) and a second adjustment drive (2') for adjusting the steering column in a vertical adjustment direction (Z), wherein: the first and second adjustment drive (2, 2') each have a drive motor (20, 20') for adjusting the steering column (1); the two drive motors (20, 20') have a common control unit (50) which comprises three half bridges (HB1, HB2, HB3) which are arranged in parallel and connected between two voltage potentials; the half bridges (HB1, HB2, HB3) each have two switching elements (S1, S2, S3, S4, S5, S6) connected in series, one of the switching elements being a high-side switch (S1, S2, S3) and the other switching element being a low-side switch (S4, S5, S6), a connection point being formed between a high-side switch (S1, S2, S3) and a low-side switch (S4, S5, S6) in each half bridge (HB1, HB2, HB3); and the connection point of a first half bridge (HB1) is electrically conductively connected to a first connection of a first drive motor (20) of the two drive motors (20, 20'), the connection point of a second half bridge (HB2) is electrically conductively connected to a second connection of the first drive motor (20), the connection point of a third half bridge (HB3) is electrically conductively connected to a second connection of a second drive motor (20') of the two drive motors (20, 20'), and the connection point of the second half bridge (HB2) is electrically conductively connected to a first connection of the second drive motor (20').
