  • Patent number: 6178841
    Abstract: A manually controlled operating lever for a vehicle operator's platform has an electrical actuation transducer for transmitting control signals to a working function as a function of the pivoting of the lever and/or as a function of the actuation of at least one actuation element arranged on the lever. In order to avoid an undesired release of working functions, a manually operated activating element is mounted near a hand grip of the lever, and is coupled to a switching element which operates to activate the actuation transducer for the transmission of control signals as a function of actuation of the activating element.

  • Patent number: 6002976
    Abstract: A vehicle power shift transmission (PST) is controlled by a transmission control system which implements a control method. The PST is part of the driveline of the vehicle and is shifted by an actuating mechanism. The driveline includes an engine, the PST, a clutch, a synchronized shift transmission that can be shifted by a shift lever and driven vehicle wheels. In order to simplify the operator's tasks, during the shift of the synchronized shift transmission the gear of the PST is automatically shifted so that the resulting difference in the gear ratio of the complete transmission before and after the shift is minimized. The gear of the PST is selected and shifted automatically so that the rotational speeds on both sides of the clutch differ as little as possible.
