Abstract

A brake pedal module for a brake-by-wire braking system of a vehicle is disclosed, with a carrier component for attaching the brake pedal module to the vehicle, a brake pedal mounted pivotably on the carrier component, a feedback unit which, to generate a resistance on actuation of the brake pedal, is mechanically coupled at one end to the brake pedal and at the other end to the carrier module, and a sensor unit for detecting a braking request of a driver and having at least one sensor for detecting an actuation travel. The sensor unit is attached to the carrier component at the side of the brake pedal such that the sensor is arranged on a pivot bearing of the brake pedal.

First claim

The invention claimed is:

1. A brake pedal module for a brake-by-wire braking system of a vehicle, comprising a carrier component for attaching the brake pedal module to the vehicle, a brake pedal mounted pivotably on the carrier component, a feedback unit which, to generate a resistance on actuation of the brake pedal, is mechanically coupled at one end to the brake pedal and at the other end to the carrier module, and a sensor unit for detecting a braking request of a driver and having at least one sensor for detecting an actuation travel, wherein the sensor unit is attached to the carrier component at the side of the brake pedal such that the sensor is arranged on a pivot bearing of the brake pedal, wherein a joint pin is molded on the brake pedal and protrudes through the carrier component in the pivot bearing, wherein a measuring element, which is used by the sensor unit for detecting the position of the brake pedal, is arranged on the end face of the joint pin.

2. The brake pedal module as claimed in claim 1 , wherein the sensor unit is a premounted unit.

3. The brake pedal module as claimed in claim 2 , wherein the brake pedal is pivotably received between the shell-like components.

4. The brake pedal module as claimed in claim 2 , wherein the carrier component comprises two shell-like components which are attached to one another and delimit an accommodation space for accommodating the feedback unit.

5. The brake pedal module as claimed in claim 4 , wherein a joint pin is molded on the brake pedal and protrudes through the carrier component in the pivot bearing, wherein a measuring element, which is used by the sensor unit for detecting the position of the brake pedal, is arranged on the end face of the joint pin.

6. The brake pedal module as claimed in claim 5 , wherein the feedback unit has a first counterforce unit loading the brake pedal into a rest position, and at least one further counterforce unit acting parallel to the first counterforce unit and/or a damping unit acting parallel to the first counterforce unit.

7. The brake pedal module as claimed in claim 6 , wherein the brake pedal is configured as a standing brake pedal.

8. The brake pedal module as claimed in claim 4 , wherein the brake pedal module is a premounted, force-enclosed structural unit which can be attached to the vehicle via the carrier module.

9. The brake pedal module as claimed in claim 1 , wherein the carrier component comprises two shell-like components which are attached to one another and delimit an accommodation space for accommodating the feedback unit.

10. The brake pedal module as claimed in claim 9 , wherein the brake pedal is pivotably received between the shell-like components.

11. The brake pedal module as claimed in claim 9 , wherein the sensor unit is arranged outside the accommodation space.

12. The brake pedal module as claimed in claim 1 , wherein the feedback unit has a first counterforce unit loading the brake pedal into a rest position, and at least one further counterforce unit acting parallel to the first counterforce unit and/or a damping unit acting parallel to the first counterforce unit.

13. The brake pedal module as claimed in claim 1 , wherein the brake pedal is configured as a standing brake pedal.

14. The brake pedal module as claimed in claim 1 , wherein the brake pedal module is a premounted, force-enclosed structural unit which can be attached to the vehicle via the carrier module.

15. A brake pedal module for a brake-by-wire braking system of a vehicle, comprising a carrier component for attaching the brake pedal module to the vehicle, a brake pedal mounted pivotably on the carrier component, a feedback unit which, to generate a resistance on actuation of the brake pedal, is mechanically coupled at one end to the brake pedal and at the other end to the carrier module, and a sensor unit for detecting a braking request of a driver and having at least one sensor for detecting an actuation travel, wherein the sensor unit is attached to the carrier component at the side of the brake pedal such that the sensor is arranged on a pivot bearing of the brake pedal, wherein the feedback unit has a first counterforce unit loading the brake pedal into a rest position, and at least one further counterforce unit acting parallel to the first counterforce unit and/or a damping unit acting parallel to the first counterforce unit.

16. A brake pedal module for a brake-by-wire braking system of a vehicle, comprising a carrier component for attaching the brake pedal module to the vehicle, a brake pedal mounted pivotably on the carrier component, a feedback unit which, to generate a resistance on actuation of the brake pedal, is mechanically coupled at one end to the brake pedal and at the other end to the carrier module, and a sensor unit for detecting a braking request of a driver and having at least one sensor for detecting an actuation travel, wherein the sensor unit is attached to the carrier component at the side of the brake pedal such that the sensor is arranged on a pivot bearing of the brake pedal, wherein the feedback unit has a first counterforce unit loading the brake pedal into a rest position, and at least one further counterforce unit acting parallel to the first counterforce unit and/or a damping unit acting parallel to the first counterforce unit, wherein the sensor unit is a premounted unit, wherein the carrier component comprises two shell-like components which are attached to one another and delimit an accommodation space for accommodating the feedback unit, wherein a joint pin is molded on the brake pedal and protrudes through the carrier component in the pivot bearing, wherein a measuring element, which is used by the sensor unit for detecting the position of the brake pedal, is arranged on the end face of the joint pin.

17. The brake pedal module as claimed in claim 16 , wherein the feedback unit has a first counterforce unit loading the brake pedal into a rest position, and at least one further counterforce unit acting parallel to the first counterforce unit and/or a damping unit acting parallel to the first counterforce unit.
