Abstract:
In a motor vehicle having wheels, a brake system comprising:a brake pedal;a pedal unit having at least two sensors for sensing activations of said brake pedal and supplying sensor signals;at least two parallel central units for calculating setpoint values for a brake activation force from the sensor signals and for converting the setpoint values together with unprocessed sensor signals, into a serially encoded signal;a multi-channel signal line connecting said pedal unit and said central units to one another for transmitting the sensor signals;electromechanical brake actuators assigned to the wheels;decentralized control units associated with said brake actuators for comparing the setpoint values during fault-free operation, for comparing the sensor signals in the event of a fault and for generating control signals on the basis of the setpoint values and sensor signals; andtwo data buses each respectively connecting one of said central units and two of said brake actuators to one another for serially transmitting the encoded signals.
