Abstract: A door control system for a vehicle includes a compressor, an air dryer, a door control valve and at least one cylinder that can be actuated by compressed air. A piston of the cylinder can occupy a first functional position and a second functional position. The air dryer, in drying mode, is exposed to throughflow of the air flowing into the cylinder, and in regeneration mode is exposed to throughflow by the air discharging from the cylinder. The cylinder is pressurized only with compressed air from a compressed air accumulator.

Abstract: The invention relates to a door control system for vehicles, with a compressor (1), an air dryer (3), a door control valve (4) and at least one cylinder (2) which can be actuated by compressed air, and also relates to a method for actuating a cylinder (2) of a vehicle door, in which a piston (13) of the cylinder (2) can occupy a first functional position (O) and a second functional position (X). The air dryer (3), in drying mode, is exposed to throughflow of the air flowing into the cylinder (2) and in regeneration mode is exposed to throughflow by the air discharging from the cylinder (2). The cylinder (2) is pressurised only with compressed air from a compressed air accumulator (7).
