DRIVE SYSTEM AND METHOD FOR CHARGING OF A BATTERY OF A HYBRID VEHICLE

摘要

A drive system and a method of driving a vehicle, wherein the drive system includes a combustion engine, a motor control function, a gear box, an electric machine, an energy storage and a planetary gear. A control unit receives information concerning the charge level of the energy storage and determines if the charge level is lower than a limit level such that the energy storage needs charging. If this is the case, the motor control function is controlled such that the combustion engine increases rotation speed in relation to the rotation speed when the energy storage does not need charging.
