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