Abstract

A modularly constructed electronic motor vehicle control system, includes wheel speed sensor inputs, at least one brake controller, and inertial sensors. The signals from the wheel speed sensors are fed into a chassis base module. The module evaluates the signals and feeds them to an electronic brake controller spatially separated from the chassis base module. The chassis base module and the brake controller are disposed in separate control device housings.

Claims

1-10. -10. (canceled)

11. An electronic motor vehicle control system which is of modular design, said electronic motor vehicle control system comprising:

a wheel speed sensor input, at least one brake controller and inertial sensors; and

a chassis base module to which signals of wheel speed sensors are transmitted, wherein the module is configured to evaluate the signals and transmit them to an electronic brake controller which is arranged in a spatially separated fashion from the chassis base module,

wherein the chassis base module and the brake controller are arranged in separate control device housings.

12. The system as claimed in claim 11 further comprising a hydraulic unit, wherein hydraulic valves for actuating brakes are integrated with the hydraulic unit, and wherein the electronic brake controller and the hydraulic unit form one integrally connected unit.

13. The system as claimed in claim 12, wherein the electronic brake controller and the hydraulic unit permanently form one integrally connected unit.

14. The system as claimed in claim 11, wherein the inertial sensor or sensors is/are integrated into or onto a housing of the chassis base module.

15. The system as claimed in claim 11, wherein the chassis base module is configured to form a safety domain control unit which contains at least one ESC module with ESC control functions.

16. The system as claimed in claim 15, wherein the brake controller does not comprise any ESC control functions.

17. The system as claimed in claim 11, wherein a steering angle is sensed and the sensing of the steering angle takes place in a region which is spatially separated from a brake system and from the chassis base module.

18. The system as claimed in claim 11, wherein the wheel speed sensors are active magnetic field sensors which transmit wheel speed information.

19. The system as claimed in claim 18, wherein the active magnetic field sensors transmit additional information to a wheel signal processor via a current interface.

20. The system as claimed in claim 19,

wherein the chassis base module is configured to form a safety domain control unit which contains at least one ESC module with ESC control functions, and

wherein the wheel speed signal processor is integrated into the chassis base module or the safety domain control unit.

21. The system as claimed in claim 20, wherein the safety domain control unit comprises at least one chassis control function.

22. The system as claimed in claim 11 further comprising a plurality of brake controllers.

23. The system as claimed in claim 22, wherein the plurality of brake controllers are configured for wheel-specific, axle-specific or brake-circuit-specific actuation of brake actuators.

24. The system as claimed in claim 23, wherein the brake actuators are hydraulic brake actuators or electrical brake actuators.
