Abstract:
A method for accelerating a vehicle driving forward, in which the vehicle has a propulsion system including a combustion engine with an output shaft ( 2 a ), a gearbox ( 3 ) with an input shaft ( 3 a ), an electric machine ( 9 ) comprising a stator and a rotor, and a planetary gear comprising a sun gear ( 10 ), a ring gear ( 11 ) and a planet wheel carrier ( 12 ). When accelerating the vehicle the torque of the electric machine is controlled and the rotational speed of the combustion engine is controlled until the components of the planetary gear have the same rotational speed and may be interlocked.

Claim (Index 1):
A method for accelerating a vehicle driving forward, wherein the vehicle has a propulsion system comprising a combustion engine with an output shaft, a gearbox with an input shaft, an electric machine comprising a stator and a rotor, and a planetary gear comprising three components in the form of a sun gear, a ring gear and a planet wheel carrier;\n the output shaft of the combustion engine is connected to one of the three components of the planetary gear so that rotation of the output shaft causes rotation of the one of the three components, the input shaft of the gearbox is connected to another one of the three components of the planetary gear so that rotation of the input shaft causes rotation of the another one of the three components, and the rotor of the electric machine is connected to the remaining one of the three components of the planetary gear so that rotation of the rotor causes rotation of the remaining one of the components; the propulsion system further comprising locking means comprising a displaceable coupling transferable between a locking position in which two of the three components are interlocked, so that the three components rotate with the same rotational speed, and a releasing position in which the three components are allowed to rotate with different rotational speeds; the method comprising: accelerating the vehicle when the vehicle is being driven forward by, a) controlling the electric machine to deliver a torque corresponding to a product of the propulsion system torque requested for the acceleration and a transmission ratio of the planetary gear with the locking means in the releasing position, b) with the locking means in the releasing position and at the same time as step a) measuring a first rotational speed of the input shaft of the gearbox and controlling the combustion engine with an electric control unit to increase the rotational speed of the combustion engine in the direction towards the first rotational speed, and c) transferring the locking means to the locking position when the rotational speed (n1) of the combustion engine is substantially equal to the first rotational speed (n2).
