    BACKGROUND ART ln order to reduce fuel consumption hybrid vehicles are used. A hybridvehicle comprises an electric motor arrangement for driving the vehicle and acombustion engine for driving the vehicle. Such hybrid vehicles may also beprovided with an air processing system for supplying compressed air to an airsuspension system for air suspension and also to other systems including thebrake system of the vehicle. The combustion engine is hereby configured tooperate a compressor for providing compressed air for the air processingsystem. lt is desirable to drive the vehicle solely by means of the electricmotor as much as possible in order to facilitate energy efficient drive and alsofor silent drive of the vehicle. When the vehicle is driven solely by means ofthe electric motor the combustion engine and thereby said compressor arenot in operation, whereby no compressed air is supplied to the air processingsystem. This limits the possibility ofdriving the vehicle solely by means of theelectric motor, as a certain level of compressed air is needed for e.g. thebrake system OBJECTS OF THE INVENTION An object of the present invention is to provide a method for facilitating electric drive of a hybrid vehicle which further reduces fuel consumption.
    Another object of the present invention is to provide a system for facilitating electric drive of a hybrid vehicle which further reduces fuel consumption.

    Specifically an object of the invention is achieved by a method for facilitatingelectric drive of a hybrid vehicle. The hybrid vehicle comprises an electricmotor arrangement for driving the vehicle and a combustion engine fordriving the vehicle and configured to operate a compressor for providingcompressed air for an air processing system of said vehicle. The airprocessing system supplies compressed air to the air suspension system ofsaid vehicle. The method comprises the step of controlling the operation ofsaid air suspension system in order to save compressed air of the amount ofcompressed air available during drive of the vehicle solely by means of theelectric motor arrangement, the combustion engine and thereby saidcompressor not being in operation. By thus controlling the operation of saidair suspension system in order to save compressed air the vehicle may bedriven solely by means of the electric motor arrangement for a longer time, thus reducing fuel consumption and facilitating silent drive to a larger extent.
    According to an embodiment of the method the step of controlling the operation of said air suspension system comprises the step of turning off the air suspension system. Hereby no air is consumed by means of the airsuspension system thus facilitating longer drive solely by means of the electric motor arrangement.
    According to an embodiment of the method the step of controlling theoperation of said air suspension system comprises the step of increasing aninterval of allowable level changes controlled by the air suspension systemand thereby impairing the damping efficiency of said air suspension systemof the vehicle. Hereby drive solely by means of the electric motorarrangement may be increased and still maintaining a certain damping function by means of the air suspension system.
