Abstract: A method and a system (200) for providing an auxiliary unit control profile for controlling an auxiliary unit (201) in a motor vehicle (202) including receiving travelling route data relating to a travelling route of the motor vehicle and based thereon, identifying an expected future travelling route. Based on the expected future travelling route and on auxiliary unit operation data, an auxiliary unit control profile for controlling the auxiliary unit during travel along the expected future travelling route is determined in a processing unit (204). The auxiliary unit control profile is outputted to a control unit (206) configured to execute the auxiliary unit control profile and control the auxiliary unit based on the auxiliary unit control profile.

Abstract: A method for damping a power train oscillation in a vehicle provided with a prime mover which rotates at a speed ?. A vibration change S in the rotation speed ? of the prime mover is determined. There is deemed to be a power train oscillation if for a predetermined number of times the amplitude of the vibration change S is alternately above a positive threshold value Th1 and below a negative threshold value Th2 and if all of the consecutive upward crossings of the positive threshold value Th1 and downward crossings of the negative threshold value Th2 are separated by a time shorter than a predetermined period T.

Abstract: A method for damping of a power train oscillation in a vehicle provided with a prime mover which delivers a torque related to a torque request M from a vehicle system and rotates at a speed ?. A cyclic variation S in the rotation speed ? of said prime mover is determined. The torque request M is then given an oscillation-damping characteristic by use of the cyclic variation S, making it possible for the power train oscillation to be effectively damped out.
