The invention creates a vehicle pneumatics overpressure regulating circuit 1 of a supply device of a pneumatic consumer 5 in a vehicle with an operating pressure. The overpressure circuit 1 has a compressed air source 3, which furnishes compressed air for the consumer 5; a pressure switch 8, by means of which the compressed air source 3 is turned on and/or off to supply the consumer 5 with compressed air; and a supply line 4, by way of which compressed air can be carried from the compressed air source 3 to the consumer 5. The pressure switch 8 can be subjected to a measured pressure via a pneumatic measurement line 7, which is separate from the supply line, and this measured pressure characterizes a state of the operating pressure of the consumer. As a result, extremely precise regulation of the requisite operating pressure is successfully achieved.
