Pedal value generator for a motor vehicle, pedal value generator arrangement and method for controlling a motor vehicle
A pedal value generator 14 for a motor vehicle 30 , a pedal value generator arrangement 10 and a method for controlling a motor vehicle 30 are described. A first pedal actuating surface 16 and, at a distance thereto, a second pedal actuating surface 18 are arranged on a cross member 20 . A sensor arrangement 24 detects a torque M of the cross member 20 with respect to a torque axis X arranged between the first and second pedal actuating surfaces 16, 18 and for supplying an electrical actuation signal B 1 , B 2 as a function of torque M. When an actuating force acts upon first pedal actuating surface 16 motor vehicle 30 can be accelerated and when an actuating force acts upon second pedal actuating surface 18 it can be decelerated.
1. A pedal value generator for a motor vehicle, comprising
a cross member with a first pedal actuating surface and a second pedal actuating surface arranged at a distance from the first pedal actuating surface,
and a sensor arrangement for detecting a torque of the cross member with respect to a torque axis arranged between the first and second pedal actuating surfaces and for supplying an electrical actuation signal as a function of the torque;
wherein
the cross member is arranged on a pedal arm,
the pedal arm is arranged at least substantially rigid with respect to an actuation by a force acting on the first and second pedal actuating surfaces,
wherein
the pedal arm is pivotable about a pivot axis between an operating position and a rest position,
the pivot axis forms an angle with the torque axis.
2. The pedal value generator according to claim 1 , wherein
the cross member is arranged at least substantially rigid.
3. The pedal value generator according to claim 1 , wherein
a locking member for locking the pedal arm in the operating position is provided.
4. The pedal value generator according to claim 1 , wherein
a cylinder member is provided for adjusting the pedal arm.
5. The pedal value generator according to claim 1 , wherein
a separating member is arranged between the first and second pedal actuating surfaces, the separating member extending at least substantially perpendicular to at least a portion of at least one of said pedal actuating surfaces.
6. The pedal value generator according to claim 1 , wherein
the first and second pedal actuating surfaces are arranged at least substantially in parallel to one another,
the first pedal actuating surface is arranged offset relative to the second pedal actuating surface in an actuation direction.
7. The pedal value generator according to claim 1 , comprising
an evaluation unit for evaluating the torque and for supplying an acceleration signal when an actuating force is acting upon the first pedal actuating surface, and for supplying a brake signal when an actuating force is acting upon the second pedal actuating surface.
8. A pedal value generator arrangement, comprising
a legroom of a motor vehicle,
and a pedal sensor according to claim 1 that is arranged therein.
9. A method for controlling a motor vehicle wherein
the detected torque of a pedal value generator according to claim 1 is evaluated and the motor vehicle is accelerated when an actuating force is acting upon the first pedal actuating surface and is decelerated when an actuating force is acting upon the second pedal actuating surface.
