Abstract

A selection device for shifting a vehicle transmission, with a operating element (4), which can be rotated into different shift positions (6, 7, 8, 9) about an axis of rotation (5) and with a shaft (21), which is connected to the operating element (4) and is rotatable about the axis of rotation. An angle of rotation sensing device (32) is connected to the shaft, by which a rotation of the operating element (4) about the axis of rotation (5) can be sensed. An actuator (22) is provided by which a torque can be applied to the shaft (21) or a torque can be applied to oppose a rotation of the shaft (21). A control is connected to the angle of rotation sensing device (32) and to the actuator (22) for controlling the torque. The vehicle transmission (10) can be shifted into shift states (P, R, N, D) assigned to the shift positions (6, 7, 8, 9), wherein the shaft (21) extends along the axis of rotation (5) between the angle of rotation sensing means (32) and the operating element (4), which is designed as a rotary knob or button and is arranged at a first end (28) of shaft (21).
