20150142239 | METHOD FOR DRIVING A HYBRID VEHICLE IN CONNECTION WITH START OF THE COMBUSTION ENGINE OF THE VEHICLE - A method for driving a hybrid vehicle with a propulsion system including a combustion engine, an electric machine with a rotor and a stator and a planetary gear with three components including a sun gear, a ring gear and a planet wheel carrier, where an output shaft of the combustion engine is connected to a first component, an input shaft of a gearbox is connected to a second component and the rotor of the electric machine is connected to a third component. The vehicle is driven forward by the electric machine. The reverse gear engaged in the gearbox drives the third component of the planetary gear to rotate with a negative rotational speed while a brake brakes the first component. Thereafter, move the component brake to an open position, so that the output shaft of the combustion engine rotates with a positive rotational speed so that the combustion engine may be started. | 05-21-2015 |
20150148187 | METHOD FOR BRAKING A VEHICLE - A method for braking a vehicle driving forward towards stop. The vehicle has a propulsion system including a combustion engine with an output shaft ( | 05-28-2015 |
20150149012 | DRIVE SYSTEM AND METHOD FOR CHARGING OF A BATTERY OF A HYBRID VEHICLE - 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. | 05-28-2015 |
20150149013 | METHOD FOR SIMULTANEOUS CONTROL OF TORQUE FROM COMBUSTION ENGINE AND ELECTRIC MACHINE IN A HYBRID VEHICLE - A method for driving a vehicle having 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 a sun gear, a ring gear and a planet wheel carrier. The vehicle is driven with the members of the planetary gear interlocked. The planetary gear is brought to the releasing position by controlling the torque of the electric machine and of the combustion engine towards torque balance in the planetary gear. | 05-28-2015 |
