Control method for a compressed air supply system, control device, and vehicle

A control device for controlling a compressed air supply system for a vehicle, wherein the control device is assigned to the compressed air supply system for supplying a compressed air consumer via a compressed air supply port, and the compressed air supply system has a compressed air provider for providing compressed air at a compressed air port, a pneumatic main line with an air dryer for drying and directing the compressed air to the compressed air supply port in a filling direction, and a branch line emanating from the pneumatic main line in the filling direction upstream of the air dryer and reconnecting downstream of the air dryer, the control device comprising:

• a controller having an input configured to receive a supply demand of the compressed air consumer;
• said controller being configured to actuate the compressed air provider and being connected for signals to the compressed air consumer and the compressed air provider;
• and,
• said controller being configured to identify a regeneration implementation time as a function of at least one of the supply demand and a saturation level of the air dryer;
• and,
• said controller being further configured to control a branch line switch valve to fluidically open a branch line pneumatically when the regeneration implementation time is identified.

A vehicle comprising:

• a compressed air supply system for supplying a compressed air consumer via a compressed air supply port;
• said compressed air supply system having a compressed air provider for providing compressed air to a compressed air port, a pneumatic main line with an air dryer for drying and conducting compressed air to said compressed air supply port in a filling direction, and a branch line emanating from said pneumatic main line in the filling direction upstream of said air dryer and reconnecting downstream of said air dryer;
• a control device assigned to said compressed air supply system;
• said control device being configured to receive a supply demand of said compressed air consumer and to actuate said compressed air provider and to be connected for signals to said compressed air consumer and said compressed air provider;
• and,
• said control device being further configured to identify a regeneration implementation time as a function of at least one of the supply demand and a saturation level of said air dryer and to control a branch line switch valve to fluidically open said branch line pneumatically when the regeneration implementation time is identified.
