Patent ID: 8745982

Claim:
A method for regenerating a compressed air supply device of a commercial vehicle, wherein the compressed air supply device has an air dryer and is capable of supplying a first compressed air circuit and a second compressed air circuit with compressed air, wherein the first compressed air circuit is assigned a predetermined maximum pressure value, the method comprising the acts of: supplying the first compressed air circuit with compressed air until the pressure in the first compressed air circuit has reached a predetermined target pressure value; subsequently supplying the second compressed air circuit with compressed air; wherein between the supplying of the first compressed air circuit and the subsequent supplying of the second compressed air circuit, the method further comprises the acts of: (a) regenerating the air dryer with compressed air from the first compressed air circuit, when the pressure in the first compressed air circuit has reached the target pressure value, and when a moisture value of the air dryer exceeds a predetermined target moisture value; (b) terminating the regeneration, when the pressure in the first compressed air circuit has dropped to a predetermined limit pressure value, or the moisture value of the air dryer has reached or dropped below the target moisture value; (c) supplying the first compressed air circuit with compressed air until the first compressed air circuit has reached the predetermined target pressure value; repeating steps (a)-(c) when the moisture value of the air dryer is greater than the target moisture value.
