摘要： In a method performed by a control unit for controlling energy flows of a vehicle, where the vehicle includes a vehicle energy system which in turn includes a plurality of energy subsystems. Within each energy subsystem one form of energy is used. The energy subsystems are operationally connected by converters, wherein converters are devices converting at least one form of energy to another form of energy. By setting a price, limits for the converters converting energy between the energy subsystem the energy flows of the vehicle can be controlled by the control unit such that at least during period of times the order in which the energy subsystems of the vehicle is provided with energy can be changed.

摘要： The invention relates to a drive arrangement for a vehicle and a method for gear shifting in a vehicle. The drive arrangement (5) comprises at least a first drive axle (10, 20, 30) operatively connected to a first gear box (11) and a first propulsion unit (12). The drive arrangement (5) further comprises a second gear box (21) and a second propulsion unit (22) operatively connected to the first drive axle (10) or to an optional second drive axle (20, 30). The drive arrangement (5) further comprises at least one electronic control unit (ECU) adapted to govern gear transmission of the first and the second gear boxes (11, 21). The electronic control unit (ECU) is configured to automatically select between shifting gear on the first and the second gear boxes (11, 21) simultaneously, or sequentially. The drive arrangement and the method provides for a very versatile drive arrangement and gear synchronization providing comfort for the driver and the passengers as well as improved vehicle dynamics.

摘要： A method for improving startability of a vehicle is provided, the vehicle being provided with a prime mover and a kinetic energy recuperation system. The prime mover is adapted to propel the vehicle either alone or in combination with the kinetic energy recuperation system which is operably coupled to the prime mover and to wheels of the vehicle and is adapted to store energy at times when there is an abundance of energy and to use energy at times when there is a demand for energy. A vehicle is also provided. The method includes determining that the vehicle is standing still or essentially standing still; detecting a take-off assistance condition; detecting a level of energy in the kinetic energy recuperation system; if the level of energy is found insufficient, connecting the prime mover to the kinetic energy recuperation system and running the prime mover such that energy from the prime mover is stored in the kinetic energy recuperation system; and when a driver requests the vehicle to take off, running the prime mover and consuming energy from the kinetic energy recuperation system such that the wheels of the vehicle initiate propelling thereof.
