摘要： The invention relates to a PTO brake control system. There is a need for an improved and safe PTO brake control system. A PTO may be put into a driven and a non-driven condition an is braked by a PTO brake. A PTO brake control system includes a vehicle speed sensor and an ECU for controlling the PTO brake. The ECU deactivates the PTO brake when the vehicle is stationary and the PTO is not driven. This allows the PTO to be manually rotated to facilitate coupling of the PTO to an implement.

摘要： A method for adapting a drive train based upon a PTO load is provided. The method includes continually during vehicle driving determining a torque magnitude indicative of said power take off unit's torque consumption by sensing a fluid pressure produced by a power take off fluid pump. The sensed power take off unit torque consumption is continually compared with an output torque produced by a prime mover. Using the difference from said output torque expected value and the measured PTO torque consumption, a control unit adjusts transmission shifting (if automatic) of a transmission and/or prime mover control because the PTO will cause the prime mover to lose some of its available torque. Based on the PTO load, the engine control will selected the appropriate prime mover torque production and the transmission control unit will select the appropriate start gear, upshift gears, and downshift gears.

摘要： A method for controlling a power source (1, 10) of a forestry machine, wherein the power source utilizes directly or indirectly one or more work devices and/or handling devices (3, 4, 7, 8) positioned in the forestry machine and is controlled by a control unit (2). When the control unit in the forestry machine gives one or more work or handling devices a control command starting a change operation, it is transmitted substantially simultaneously to the power source. When arriving at the power source, one or more control commands requiring a power change of the power source affect control parameters of the power source, predicting the future load of the power source.

摘要： An automatic gearshifting process and/or disengagement process of a coupling-dependent power take off for a vehicle with the power take off engaged and when the vehicle is in motion. The power tapping at the power take off is minimized before a gearshift and/or disengagement of the claw clutch of the power take off takes place. One advantage is that gearshifting can be realized with engaged coupling-dependent power take off. Comfort is increased and coupling teeth wear is minimized, whilst, at the same time, a gear and the claw clutch of the power take off are able to be securely disengaged.

摘要： Method for regulating the rotational speed of a clutch-independent power take-off. The power take-off is driven by an engine arranged in a vehicle. The engine is connected to an automatic stagegeared transmission by way of an automated vehicle clutch. At least one control unit is provided for controlling the transmission, the vehicle clutch and the engine. The control unit controls the rotational speed of the engine as a function of the position of the throttle lever and controls the transmission as a function of the position of a gear selector. The rotational speed of the engine is regulated by way of a control and the degree of engagement of the vehicle clutch is regulated by way of the throttle lever when the power take-off is engaged and a drive position is selected by way of the gear selector. The rotational speed of the engine is automatically reduced when equipment engaged to the power take-off approaches a limit position.

摘要： A hydraulic transmission (21) has an electric actuator (86) for changing its output/input rotation speed ratio. A controller 90 of the actuator memorizes a command current value to the actuator supposing that load is not applied on the hydraulic transmission, and calculates a value of load applied on the hydraulic transmission by calculating a difference between an actual command current value to the actuator and the memorized command current value. A command current value is compensated based on the value of load, and the actuator receives feedback to be controlled. A vehicle may have a differential mechanism (10), which combines rotation powers on input side and output side of the hydraulic transmission. A detector (82) detects rotation speed of a main speed change output shaft (27) serving as an output shaft of the differential mechanism. If the detected rotation speed differs from target rotation speed of the shaft (27) determined based on operation of a speed change operation tool, the actuator is forcedly controlled. This difference is supposed to be caused by load applied on the hydraulic transmission, whereby the load is calculated.

摘要： A work vehicle such as an agricultural tractor includes means for the operator to select between manual or automatic engine speed control and to select among multiple automatic modes each having a different amount by which the engine speed is reduced when the load is reduced and the transmission is up-shifted to maintain the vehicle ground speed. This enables the operator to match the degree of engine speed reduction to the particular task at hand for improved performance and productivity. Preferably, the transmission is an infinitely variable transmission whereby the engine speed and the transmission can both be varied infinitely.
