PNEUMATIC SYSTEM HAVING A VARIABLE PUMPING RATE

摘要

The invention relates to a pneumatic system (1) for a motor vehicle, comprising a compressed-air reservoir (2) for storing compressed air (3), a braking system (4) that is pneumatically connected to the compressed-air reservoir (2) and is used for applying a braking force to a vehicle wheel (5), a piston pump (6) for filling the compressed-air reservoir (2), and a driving device (7) that drives the piston pump (6) at a certain speed; at least one sensor (8) is provided for sensing at least one vehicle parameter, according to the value of which the speed of the driving device (7) can be modified using a control request by a control unit (10).
