  • Publication number: 20140297143
    Abstract: Method to control a drivetrain of a vehicle, wherein the vehicle is provided with a vibration sensor and a system for calculating the mass of the vehicle during driving, and where a starting gear of the transmission is automatically chosen dependent on the calculated mass of the vehicle. The method chooses a lower starting gear than the during, driving calculated mass has indicated if the vibration sensor has registered a vibration of the vehicle at stand still.
