Abstract
A system for generating air pressure in a hybrid vehicle, comprising an engine-driven air compressor (C1) configured to be selectively operated by an ICE engine, an electrically-driven air compressor (C2) configured to be operated by an electric motor, wherein said electric motor is supplied from the electric network, at least one air reservoir configured to store pressurized air and being configured to be connected directly or indirectly to both an outlet of the engine-driven air compressor (C1) and an outlet of the electrically-driven air compressor (C2), at least one electronic control unit (3, 3′) configured to control at least the electrically-driven air compressor (C2) according at least to a selected drive mode of the vehicle, wherein the electrically-driven air compressor (C2) is downsized compared to the engine-driven compressor (C1), and corresponding control methods.
