Abstract

A vehicle brake, in particular a disc brake or drum brake having pads or linings arranged on brake pad or lining carrier plates, and including an application device, is characterized in that at least one brake pad or lining of the vehicle brake is equipped with an electronic unit, which has an electronic memory for at least storing brake pad or lining specific data.

Claims

1. A vehicle brake, comprising:

a brake application device;

brake pads applied by the brake application device; and

wherein at least one brake pad comprises an electronic unit having an electronic memory for storing at least brake pad-specific data.

2. The vehicle brake according to claim 1, wherein the vehicle brake is one of a disc brake and a drum brake.

3. The vehicle brake according to claim 1, further comprising a reading and evaluation device for data transmittable by the electronic unit, the reading and evaluation device being mounted in a region outside of the brake pad.

4. The vehicle brake according to claim 3, wherein the electronic unit comprises a chip containing memory and a processor, and an antenna for signal transmission.

5. The vehicle brake according to claim 3, wherein the reading and evaluation device comprises an antenna for receiving the transmittable data.

6. The vehicle brake according to claim 4, wherein the antenna is installed on one of:

a caliper of a disc brake and a circuit board of a wear detection system of a disc brake.

7. The vehicle brake according to claim 4, wherein a caliper of the disc brake is designed as the antenna.

8. The vehicle brake according to claim 3, wherein the reading and evaluation device is installed inside one of the vehicle brake and a vehicle having the vehicle brake.

9. The vehicle brake according to claim 8, wherein when the reading and evaluation device is installed in the vehicle, the reading and evaluation device is integrated in a control unit of an ABS system of the vehicle.

10. A brake pad of a vehicle brake, the brake pad comprising:

a pad carrier plate;

pad material mounted on the pad carrier plate; and

an electronic unit comprising an electronic memory for storing at least brake pad-specific data.

11. The brake pad according to claim 10, wherein the electronic unit is arranged in the pad material.

12. A brake system, comprising:

a vehicle brake, the vehicle brake comprising a brake application device and brake pads applied by the brake application device, wherein at least one brake pad comprises an electronic unit having an electronic memory for storing at least brake pad-specific data;

a control unit of the brake system, the control unit processing the brake pad-specific data;

wherein the pad-specific data includes pad-specific parameters influencing a braking effect of the vehicle brake.

13. The brake system according to claim 12, wherein the pad-specific parameters comprise at least one of a pad quality, a pad lining area, and a pad coefficient of friction, which parameters are attained during manufacture of the brake pad.

14. The brake system according to claim 12, wherein the vehicle brake is one of a disc brake and a drum brake.

15. The brake system according to claim 12, wherein the control unit processes additional parameters supplied by the electronic unit of the brake pad.

16. The brake system according to claim 15, wherein the additional parameters comprise at least one of a quality of the brake pad, a manufacturer of the brake pad, a date of production of the brake pad, data relating to manufacturer of the brake pad, a batch production of the brake pad and a production location of the brake pad.
