In a method for controlling a vehicle with a drive system comprising an output shaft of a combustion engine and a planetary gear with a first and a second electrical machine, connected via their rotors to the components of the planetary gear, the combustion engine is started while the vehicle is driven by ensuring that the rotor of the second electrical machine is connected with the output shaft of the combustion engine, and controlling such electrical machine's rotational speed towards the combustion engine's idling speed, whereupon fuel injection into the combustion engine is carried out to start the latter.

Disclosed is a method for control of a vehicle with a drive system comprising a planetary gear and a first and second electrical machine, connected with their rotors to the components of the planetary gear, a braking of the vehicle towards stop occurs by way of a distribution of the desired braking torque between the first and the second electrical machines, and wherein such electrical machines are controlled to transmit a total torque to an output shaft of the planetary gear, which corresponds to the desired braking torque at least to one predetermined low speed limit, before the vehicle stops.

A method of controlling operation of a vehicle is disclosed, wherein the vehicle comprises a transmission and a power source operably connected to driven wheels of the vehicle via the transmission. The transmission is controllable between at least two different gears to provide at least two different transmission ratios between the power source and the driven wheels of the vehicle. The method comprises the steps of selecting a starting gear in the transmission based on an inputted target speed, and then accelerating the vehicle from standstill with the starting gear engaged in the transmission. The present disclosure further relates to a computer program, a computer-readable medium, a control arrangement, and a vehicle.

A power split hybrid transmission for a vehicle includes an internal combustion engine (ICE), a first electric motor, a second electric motor, a disconnect element and a controller. The ICE drives an output shaft that is rotatably coupled to a planetary carrier of a planetary gear set. The first electric motor is rotatably coupled to a sun gear of the planetary gear set and provides a first rotatable input to a transmission output shaft. The second electric motor is rotatably coupled to a counter gear that provides a second rotatable input to the transmission output shaft. The disconnect element selectively disconnects rotatable motion from the transmission output shaft to drive wheels. The controller determines whether the ICE, the first electric motor and the second electric motor are disconnected from the drive wheels and commands torque to the first and second electric motors to cooperatively rotate the transmission output shaft.

A number of illustrative variations may include a system including brake-to-steer algorithms may achieve lateral control of a vehicle without longitudinal compensation but may also force a vehicle to slow down too rapidly before appropriate lateral movement can be achieved and may deliver an unnatural driving experience for vehicle occupants. A more natural feeling deceleration may be achieved by optimally selecting appropriate transmission shifts to allow for optimal engine speed or electric motor speed and torque based on current vehicle speed thereby reducing undesirably longitudinal disturbance.
