    摘要: The engine speed control system for a work vehicle has a foot accelerator controller for carrying out foot accelerator control based on a pedal sensor, a hand accelerator controller for carrying out hand accelerator control based on a lever sensor, a manually operated input device, storage means for storing a predetermined engine speed, and a constant rotation controller for carrying out constant rotation control in which the engine speed stored in the storage means is used as the target rotational speed on the basis of an input to the input device. The constant rotation control is carried out when the input device has been operated in the case that the engine speed that corresponds to the output of the lever sensor is greater than an idling speed, and the constant rotation control is terminated when the input device is operated in the case that the engine speed that corresponds to the output of the lever sensor is equal to or less than the idling speed.

    摘要: A work vehicle with a speed change device, comprises, a plurality of wheels including at least one driven wheel; an engine for driving the driven wheel; a speed change device provided between the driven wheel and the engine; and automatic shifting mechanism. The automatic shifting mechanism is capable of operating the speed change device to a lower speed position within an automatic shifting range having a predetermined range and is capable of operating the speed change device up to a speed position which the speed change device was in before an operation to the lower speed position was effected, in response to load on the engine. The entirety of the automatic shifting range is changeable to a low speed side and to a high speed side or the automatic shifting range can be widened to include more speed positions and narrowed to include less speed positions.

    摘要: The invention provides a circuit for supplying electric power to a load using a high voltage battery, the circuit supplying a dark current when the load is not being operated. A high voltage load and a low voltage load are attached to a battery and electric power is supplied to the low voltage load through a main DC-DC converter and a sub DC-DC converter. When an ignition switch is OFF, only the sub converter supplies the dark current to the low voltage load and the main DC-DC converter is turned OFF. When the ignition switch is ON, the main DC-DC converter supplies required electric power. Since a low-capacity sub DC-DC converter supplies the dark current, the battery discharge can be prevented.

    摘要: In a power supply system in which a load is connected to a battery, the battery is efficiently charged without degrading the characteristics of the load. When a load that deteriorates in characteristics if a voltage exceeding the rated voltage of the load is applied thereto is connected to the battery (during an on-state of the load), the battery is charged with the rated voltage even if there is a need to charge the battery with a charging voltage higher than the rated voltage. Alternatively, the battery may be charged for a predetermined time at a voltage above the rated voltage and then at or below the rated voltage, or the voltage seen by the load may be converted to a voltage at or below the rated voltage while the battery is being charged at a voltage above the rated voltage. When the load is off, the battery is charged with a voltage higher than the rated voltage.

    摘要: Provided is a tractor which allows continuation of a plowing work by appropriately elevating a plow when slip occurs in wheels. The tractor includes draft controlling means (34) for elevating the plow to a target machine body level value obtained by making reference to control information with a draft load value detected by a draft load sensor (S). The control information is set based on a target plowing depth set when the plow was set to a target plowing depth and a draft load value. When a slip ratio detected by a slip ratio acquiring means (37) exceeds a threshold value, in place of previously set control information, there is newly set control information which renders higher the target machine body level relative to a same draft load value, thereby to elevate the plow.
