    摘要： In vehicles designed to pick up and process crops, drive units affect the ground drive, which is an all-wheel drive, which acts on all of the wheels and/or track roller unit in contact with the ground, electronic controls and actuators perform the control and regulation of the drive units, and control units that control the drive torque at the wheels are used to obtain good traction and minimal slippage of the wheels on the ground. To control the drive torques, sensors are used at particular points, the signals and data of which are processed by the control device in order to predetermine a torque or intake volume requirement. The preselection of torque in the control results in the intake volume of the hydraulic drive motor being regulated. By specifying the intake volume required, it is possible to obtain optimal traction at one or more drive wheels, and to prevent undesired slippage of any one drive wheel in advance.

    摘要： A method is described for controlling an automatic transmission of a vehicle during deceleration arising from a force resisting forward movement arising from an incline grade and a vehicle mass. The force of resistance to forward movement is determined at least based upon the incline grade. A destination gear is calculated based upon a set of gear-specific output curves and the force of resistance. The destination gear is compared to a current gear within which the machine is operating. The programmed controller executes an early downshift schedule when the destination gear is at least two positions lower than the current gear, thereby initiating a series of downshifts of the automatic transmission from the current gear to the destination gear. During each gear shift performed according to the early downshift schedule, shifting occurs at a cross-over point between output curves of current and next lower gears.

    摘要： A method of initializing the mass of a motor vehicle after a restart, for controlling a starting process of the motor vehicle a from a standstill. During operation of the motor vehicle, its mass is computed and the determined mass values are stored and, from the stored mass values, a vehicle-specific maximum mass value and/or a vehicle-specific minimum mass value is determined. The vehicle-specific maximum mass value and/or the vehicle-specific minimum mass value, determined in this manner, is subsequently used for initializing the mass of the motor vehicle after restarting the vehicle.
