Embodiment Construction

[0021] figure 1 In a simplified plan view, a motor vehicle 1 is shown, which has an advantageous parking brake system 2 . The motor vehicle 1 has a drive train 3 comprising a drive machine 4 , in the present case an internal combustion engine, and a manual or automatic transmission 5 , which can be operated via a clutch that can be actuated 6 are operatively connected to each other. The drive train 3 is operatively connected to at least two drive wheels 7 of the motor vehicle 1 in order to generate a drive torque and transmit it to a roadway in order to propel the motor vehicle 1 .

[0022] Motor vehicle 1 also has a service brake system 8 with a plurality of wheel brakes 9 which are each assigned to one of the wheels of motor vehicle 1 . The wheel brakes 9 can be hydraulically actuated as service brakes, in particular by actuating a brake pedal 10 . Wheel brakes 9 associated with drive wheels 7 also have an integrated parking brake 11 which can be actuated via a controller...
