摘要： A method is described for calibrating a characteristic diagram of a working machine. The characteristic diagram includes a brake pedal characteristic of a brake system and at least one clutch characteristic of a drive input clutch which, in the calibrated condition, have a nominal relationship to one another. The method having the steps of: determining a wheel-side drive output torque; determining an actual brake pedal characteristic with reference to the drive output torque; determining an actual relationship that differs from the nominal relationship by comparing the actual brake pedal characteristic with a nominal brake pedal characteristic; and calibrating the brake pedal characteristic or the clutch characteristic in such manner that the actual relationship corresponds to the nominal relationship. In addition a working machine with a control unit for carrying out the method is described.

摘要： A method for calibrating a characteristic diagram for a drive-train of a working machine, which contains a brake pedal characteristic of a brake system and a clutch characteristic of a drive clutch, in which an opening point at which the drive clutch is disengaged when a brake pedal of the brake system is actuated as a function of a pedal path, and/or a closing point at which the drive clutch is engaged when the brake pedal is released as a function of the pedal path, is calibrated. When the brake pedal is actuated and/or released an actual rotational speed profile of the drive-train is determined, the actual rotational speed profile determined is compared with a stored corresponding target rotational speed profile, and the opening point and/or closing point of the drive clutch is adapted to minimize deviation of the actual rotational speed profile from the target rotational speed profile.

摘要： A rotational speed-regulated internal combustion engine in a working machine, for example a wheel loader, shortly before the engaging a bridging clutch of a hydrodynamic torque converter, is switched over in such manner that the internal combustion engine operates under torque regulation when the bridging clutch of the hydrodynamic torque converter is engaged.

摘要： A method of starting or holding a mobile vehicle and, in particular, a working machine. The method determines whether the vehicle is rolling backward on an inclined surface and, as a function of that knowledge, the rotational speed of the drive engine is increased, or a downshift by one gear is carried out in the transmission.
