METHOD AND DEVICE FOR SELECTING A STARTING GEAR IN A HYBRID ELECTRIC VEHICLE

摘要

Method and device for selecting a starting gear in a hybrid electric vehicle (1), where a first driving sequence is registered (22) during which a parameter indicates that an electric motor energy source (9) has been drained past an energy level limit (23) and/or no gear ratio shift from said starting gear ratio has occurred. Upon detection of said driving sequence, draining of said energy source and /or no gear ratio shift, altering selection of a starting gear ratio to a gear ratio being higher (24), compared to a normal starting gear ratio, for the next vehicle take off of a driving sequence following said first driving sequence. This increases possibility that the vehicle during driving with said altered starting gear will reach a vehicle speed that corresponds to a combustion engine speed above idle speed of said combustion engine. Increased possibility of efficient charging of said energy source with said combustion engine.
