Electric brake system for a motor vehicle

An electric brake system for a motor vehicle including a plurality of wheel brakes associated with a plurality of wheels, comprising:

• a unit for receiving operating signals from at least one driver-operated brake operating element and for determining setpoints for controlling the plurality of wheel brakes on the basis of the operating signals;
• a plurality of units assigned to the plurality of wheel brakes of the motor vehicle and for converting the setpoints into control signals for the plurality of wheel brakes;
• a processing unit for determining setpoints for each one of the plurality of wheels;
• and
• at least two communication systems, wherein:
• the plurality of wheel brakes includes front wheel brakes and rear wheel brakes,
• at least one of the plurality of units assigned to the plurality of wheel brakes is assigned to the front wheel brakes,
• at least another one of the plurality of units assigned to the plurality of wheel brakes is assigned to the rear wheel brakes, and
• the at least one of the plurality of units assigned to the front wheel brakes is redundantly connected to the unit for receiving operating signals and the processing unit via the at least two communication systems and the at least one of the plurality of units assigned to the front wheel brakes receives power from at least two power sources.

An electric brake system for a motor vehicle including a plurality of wheel brakes associated with a plurality of wheels, comprising:

• a unit for receiving operating signals from at least one driver-operated brake operating element and for determining setpoints for controlling the plurality of wheel brakes on the basis of the operating signals, the unit for receiving operating signals including a computer channel for relaying setpoints for each axle of the motor vehicle;
• a plurality of units assigned to the plurality of wheel brakes of the motor vehicle and for converting the setpoints for controlling the plurality of wheel brakes into control signals for the plurality of wheel brakes;
• a processing unit for determining setpoints for each one of the plurality of wheels;
• at least two communication systems for interconnecting the unit for receiving operating signals, the plurality of units assigned to the plurality of wheel brakes, and the processing unit;
• a drive unit;
• a control unit for controlling the drive unit;
• and
• a third communication system for connecting the processing unit to the control unit, wherein, when an error occurs in the computer channel of the unit for receiving operating signals:
• the processing unit relays to the plurality of units assigned to the plurality of wheel brakes the setpoints relayed by the computer channel for each axle of the motor vehicle, instead of relaying the setpoints for each one of the plurality of wheels to the plurality of units assigned to the plurality of wheel brakes.
