A motor vehicle system comprising a first electric parking brake actuation unit assigned to a first vehicle wheel, and a second electric parking brake actuation unit assigned to a second vehicle wheel. The system further comprises a first control unit which includes at least one first microprocessor and which is designed to control the first electric parking brake actuation unit and does not allow the second electric parking brake actuation unit to be controlled. Furthermore, a second control unit is provided which comprises at least one second microprocessor and which is designed to control the second electric parking brake actuation unit and does not allow the first electric parking brake actuation unit to be controlled. The redundancy of the two control units increases the system safety. At the same time, the system complexity remains low since no individual control unit has to be designed to control all of the electric parking brake actuation units.
