Abstract
A brake system for a motor vehicle, comprising a pedal unit including a plurality of sensors generating sensor signals upon actuation of a brake pedal of a motor vehicle and further sensors generating additional brake signals. At least one electronic control unit including at least three arithmetic units are programmed to evaluate the sensor signals generated by the plurality of sensors, calculate desired values for a brake actuation force, compare the calculated desired values with each other, determine if at least two calculated desired values agree with each other within a predetermined tolerance, and upon this determination, output a wheel braking demand signal dependent upon the two agreed values. At least two of the arithmetic units are programmed to compare the additional brake signals generated by the further sensors, and if the additional brake signals agree within a predetermined tolerance, to output a corrected wheel braking demand signal. At least one electronically activated brake actuator receiving the wheel braking demand signal and the corrected wheel braking demand signal and in response thereto, applying the brake actuation force to a wheel of a motor vehicle.
