Selection Device for Shifting a Vehicle Transmission
First Claim
1. A selection device for shifting a vehicle transmission, the selection device comprising:
- an operating element designed as a rotary knob or button, which can be rotated into different shift positions about an axis of rotation;
a shaft, which is connected to said operating element and is rotatable about an axis of rotation;
an angle of rotation sensing means, which is operatively connected to said shaft and by means of which a rotation of said operating element can be sensed;
an actuator, by means of which a torque can be applied to said shaft or a rotation of said shaft can be opposed with said torque; and
a control means, which is connected to said angle of rotation sensing means and to said actuator and by means of which the torque that can be applied or applied for opposition by said actuator can be controlled, and said vehicle transmission (10) can be shifted into shift states assigned to shift positions, said shaft extending along said axis of rotation between said angle of rotation sensing means and said operating element, which is arranged at a first end of said shaft.

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).
