Abstract

A central control module generates nominal values for braking based on a pedal input value form a pedal sensor which detects actuation of the brake pedal by the driver, and sensor signals representing wheel speeds. First and second brake control modules transmit sensor signals to the central module, receive nominal values from the central module, and transmit nominal values to the actuators. The first brake control module receives the pedal input value from the pedal sensor directly, and calculates the nominal values as a function of the pedal input value when the central module has failed.
