Abstract

A brake pedal module for a brake-by-wire brake system of a vehicle is disclosed, having a brake pedal, which can be secured pivotably on the vehicle and can be moved between a rest position and an end position, and a feedback unit for producing a resistance during actuation of the brake pedal. The feedback unit has a first counterforce unit, which urges the brake pedal into the rest position, and at least one further counterforce unit, which acts in parallel with the first counterforce unit as regards their interconnection, and/or a damping unit, which acts in parallel with the first counterforce unit as regards their interconnection.

First claim

The invention claimed is:

1 . A brake pedal module for a brake-by-wire brake system of a vehicle, comprising a brake pedal, which can be secured pivotably on the vehicle and can be moved between a rest position and an end position, and a feedback unit for producing a resistance during actuation of the brake pedal, wherein the feedback unit has a first counterforce unit, which urges the brake pedal into the rest position, and at least one further counterforce unit, which acts in parallel with the first counterforce unit as regards their interconnection, and/or a damping unit, which acts in parallel with the first counterforce unit as regards their interconnection, wherein the first counterforce unit is directly connected to the brake pedal at a first position via a first actuating plunger and the at least one further counterforce unit and/or the damping unit is directly connected to the brake pedal at a second position via a second actuating plunger, wherein the second position of the brake pedal is different from the first position of the brake pedal.

2 . A brake pedal module according to claim 1 , wherein the brake pedal module has a support component for securing the brake pedal module on the vehicle, wherein the brake pedal is mounted pivotably on the support component.

3 . The brake pedal module according to claim 2 , wherein the first counterforce unit and the further counterforce unit and/or damping unit are modular units arranged separately from one another.

4 . The brake pedal module according to claim 2 , wherein the feedback unit is arranged between the brake pedal and the support component, and the feedback unit is attached to the support component.

5 . The brake pedal module according to claim 4 , wherein the feedback unit comprises a housing, in which the first counterforce unit, on one hand, and the further counterforce unit and/or damping unit, on another hand, are arranged parallel to one another.

6 . The brake pedal module according to claim 1 wherein the first counterforce unit and the further counterforce unit and/or damping unit are modular units arranged separately from one another.

7 . The brake pedal module according to claim 6 , wherein the first counterforce unit, on the one hand, and the further counterforce unit and/or damping unit, on the other hand, are each coupled at one end to the brake pedal and, at the other end, are mounted on the vehicle.

8 . The brake pedal module according to claim 1 , wherein the feedback unit comprises a housing, in which the first counterforce unit, on one hand, and the further counterforce unit and/or damping unit, on another hand, are arranged parallel to one another.

9 . The brake pedal module according to claim 8 , wherein the housing is aligned in such a way that the first counterforce unit and the further counterforce unit and/or damping unit are arranged one above the other or side-by-side or laterally offset with respect to one another in an installed state in a vehicle.

10 . The brake pedal module according to claim 8 , wherein the housing can be secured pivotably on the vehicle.

11 . The brake pedal module according to claim 10 wherein either the first counterforce unit, on one hand, or the further counterforce unit and/or damping unit, on another hand, are fixed mechanically in a pivotable manner on the brake pedal.

12 . The brake pedal module according to claim 8 , wherein the first counterforce unit and the further counterforce unit and/or damping unit are connected to one another by a transmission link.

13 . The brake pedal module according to claim 8 wherein either the first counterforce unit, on one hand, or the further counterforce unit and/or damping unit, on another hand, are fixed mechanically in a pivotable manner on the brake pedal.

14 . The brake pedal module according to claim 13 , wherein the unit from the group comprising, on one hand, the first counterforce unit and, on another hand, the further counterforce unit and/or damping unit which is not fixed mechanically in a pivotable manner on the brake pedal is supported in a sliding manner on the brake pedal.

15 . The brake pedal module according to claim 1 , wherein the first counterforce unit and the further counterforce unit and/or damping unit are connected to one another by a transmission link.

16 . The brake pedal module according to claim 15 , wherein the housing is aligned in such a way that the first counterforce unit and the further counterforce unit and/or damping unit are arranged one above the other or side-by-side or laterally offset with respect to one another in an installed state in a vehicle.
