Abstract: A method to control a brake system in a vehicle, the vehicle comprising an auxiliary brake system configured to apply a brake force to at least one first wheel of the vehicle and a foundation brake system configured to apply a brake force to at least one second wheel of the vehicle. The method comprises, when a first brake force is or is to be applied to the vehicle by means of the auxiliary brake system and when an indication of an instability condition associated with a coming road section is detected initiating a transfer of at least a part of the first brake force applied to the vehicle by the auxiliary brake system to, instead, be applied by the foundation brake system prior to reaching the coming road section to overcome the detected instability condition, such that applied brake force may be distributed over additional wheels to increase stability.

Abstract: A method performed by a control arrangement for controlling a vehicle during a downhill start, the vehicle comprising an electric machine configured to propel and/or brake the vehicle and a brake system configured to apply a brake force to the vehicle. The method comprises, following a detection of a downhill start indication, when the vehicle is maintained stationary on an inclined road section by means of a brake force applied by a brake system, controlling the electric machine to apply a brake torque while controlling the brake system to release the applied brake force, and controlling the electric machine to gradually decrease the applied brake torque to control the acceleration of the vehicle when set in motion in a downhill direction on the inclined road section. Hereby, the downhill start is performed in a controlled, safe, and predictable way resulting in an increased comfort and drivability of the vehicle.

Abstract: A control arrangement and a method for shutting down a combustion engine of a powertrain of a vehicle are disclosed. The vehicle comprises an intake air throttle arranged in an intake pipe of the combustion engine, and at least one auxiliary brake selected from the group consisting of; an exhaust brake and an electrical machine configured to operate as a generator. The method comprises in response to a command for shutdown of the combustion engine, stopping fuel injection to the combustion engine; controlling the intake air throttle so as to reduce the air intake to the combustion engine; and activating the at least one auxiliary brake so as to brake the combustion engine, if not already activated.

Abstract: A method and a system for a vehicle comprising: one or more power sources including at least one electrical machine; and a drivetrain for transferring torque between the one or more power sources and at least one drive wheel of the vehicle. The method comprises: controlling, when no positive drive torque (Tdrive) is transferred from the drivetrain to the at least one drive wheel, the at least one electrical machine to provide a backlash torque (Tbacklash) to the drivetrain, the backlash torque (Tbacklash) having a controlled value for turning the drivetrain if there is a backlash present in the drivetrain.
