  • Method for adapting an automated transmission of a heavy vehicle in consideration of a speed sensitive PTO
    Patent number: 8092342
    Abstract: Method for adapting an automated transmission of a heavy vehicle in consideration of a speed sensitive PTO. The method selects appropriate gears based on the constraint that the engaged PTO should remain below a set speed limit. The information about the speed limit of the PTO is used by the transmission control unit to ensure that the engine does not drive the PTO at a speed higher than the given speed limit. The engine speed may also be limited to reduce the engine speed to prevent it from exceeding the allowable PTO speed.
    Type: Grant

  • METHOD FOR COLD START PROTECTION OF A VEHICLE DRIVETRAIN
    Publication number: 20100286878
    Abstract: A method for cold start protection of a vehicle drivetrain is provided. If temperature is below a certain predetermined temperature limit, which is lower than normal working temperature of an engine, then maximum allowable engine torque and/or maximum allowable engine rate of rotation is/are limited to define a limited drivetrain working area adapted to cold start sensitivity of at least one of the engine, and the transmission. Transmission control is automatically adapted to prevailing limited engine working area.
