Abstract

The invention comprises a system and a method for controlling an electrical machine in a hybrid vehicle in which the power train comprises a combustion engine and a battery which is connected to said electrical machine, which system comprises: a gradient unit for determining the road gradient alpha; when the vehicle is in motion and for generating a gradient signal (L) on that basis,- a charge unit for determining the battery's state of charge (SOC) and generating a SOC signal (S) on that basis; a regulator adapted to using the gradient signal (L) and the SOC signal (S) as input signals for calculating a weighting factor and generating a weighting signal (beta) on that basis,- a torque unit adapted to determining a torque desired by the driver and to generating a torque signal (M) on that basis; a control unit adapted to calculating for the electrical machine a control signal (Y) based on the weighting signal (beta) and the torque signal (M), whereupon the electrical machine is controlled according to the control signal (Y).
