    摘要: A method of controlling an internal combustion engine (14) having a power control 15) and a variable hydrostatic transmission (16, 17) including a hydraulic pump (16) driven by the internal combustion engine, and a hydraulic engine (17) connected therewith. By automatic adjustment of the power control (15) and the ratio (E) of the hydrostatic transmission (16, 17) independently of each other according to a predetermined mathematical control function (Fig. 1) which describes a desired relationship between power and rotational speed of the internal combustion engine, a specific discrete power output is delivered between zero load and full load only at an associated discrete rotational speed of the internal combustion engine.

    摘要: A control system is provided for a combine or other vehicle having an engine (30) for driving both the ground wheels (40) of the vehicle and at least one auxiliary mechanism (42), such as the crop-processing mechanisms of a combine. The engine is coupled to the ground wheels through a hydrostatic transmission (41) and the power takeoff (43) for the auxiliary mechanism is located on the engine side of the transmission. A speed droop governor (31) regulates the fuel input to the engine in response to changes in the engine speed. Transmission control means (44, 46, 45) adjusts the setting of the hydrostatic transmission, and thus the load applied to the engine via the transmission, in , response to changes in engine speed or another parameter that varies with engine load so as to control the speed changes effected by the droop governor. The combined effect of the speed droop governor and the transmission control means is to gradually reduce the operating speed of the engine as the fuel input to the engine is increased, with the total speed reduction over the full load range of the engine comprising from about 1% to about 5% of the no-load speed.

    摘要: A control system (16) for a utility vehicle transmission provides for operator selection of vehicle "aggressiveness," or rates of acceleration in response to operator command. The aggressiveness of a vehicle's performance can be controlled by modulating control signals to proportional control valves, which determine the transmission acceleration, according to two or more electrical ramp-up (or ramp-down) profiles, in response to an operator's acceleration command (or deceleration command). The transmission control system (16) includes a controller (52), directional switches and electro-hydraulic valves (106, 108) which control hydraulic pressure in the servo control system of a hydrostatic transmission (26). The operator is provided with a two-position set switch (56). With the set switch (56) in the less aggressive position, in response to an operator's command, the software in the controller (52) provides a relatively slow current ramp to energize the control valves (106, 108). With the switch (56) in the more aggressive position, the current ramps and resultant pressure ramps are faster, thus causing more aggressive transmission operation for the hydrostatic transmission (26).

    摘要: The invention relates to a drive train control for the overall control of the drive motor and transmission of a vehicle or self-driving mobile machinery with a drive motor having a speed regulator and a continuously variable transmission with transmission ratio control. Both transmission ratio and engine speed are regulated by the drive train control which can be actuated by an accelerator pedal (1). The accelerator pedal controls the specified power output of the engine and the transmission ratio of the continuously variable transmission is adjusted in accordance with said specified power output. This allows for torque-controlled driving in push-pull mode.

There is further provided a slope descending detection means (52) which detects when the vehicle is descending down a slope, and, when it is detected by this detection means that the vehicle is descending down a slope, along with a means for engine revolution speed control (360) lowering the revolution speed of the engine (21), a displacement control means (160A) limits the maximum displacement of the hydraulic pump (1) to a value higher than during vehicle propulsion on level ground at a constant speed.
