    摘要： In the present invention, a vehicle control device 50, a controller 100, an inverter control device 30 and a steering control device 32 constitute a control device which executes the following control based on image information acquired by a camera 15: When the vehicle 1 is traveling outside a trolley wire linkage section C, the control device executes control to give a yaw moment to the vehicle 1 so that the vehicle 1 travels while tracing a trolley wire 3R/3L. When the vehicle 1 is traveling in the trolley wire linkage section C, the control device performs control not to execute the control to give the yaw moment. Further, the control device converts the acquired image information into coordinate information. Based on the coordinate information, when the vehicle 1 is traveling outside the trolley wire linkage section C, the control device calculates a representative point of the vehicle 1 and a target point situated on the trolley wire 3R/3L and gives a yaw moment to the vehicle 1 so that the representative point approaches the target point. This makes it possible to lighten the operating load on the driver during the trolley traveling and to realize stable trolley traveling even when there exists such a linkage section of trolley wires.

    摘要： A vehicle control device 50, a controller 100, an inverter control device 30 and a steering control device 32 constitute a control device 200 which controls elevation of sliders 4Ra and 4La of power collectors 4R and 4L based on information detected by a trolley wire detecting device (camera) 15. The control device 200 calculates positional relationship between a slider and a trolley wire 3R/3L based on the information detected by the trolley wire detecting device. When the slider has deviated from a prescribed range for being in contact with the trolley wire, the control device executes control to prohibit an operation for elevating the sliders or to lower the sliders when the sliders have been elevated. With this configuration, an electrically driven dump truck capable of lightening the operating load on the driver during the trolley traveling is provided.

    摘要： A method of and system for controlling a hydraulic power system comprising an internal combustion engine receiving a supply of fuel from a fuel injection pump, and at least one variable displacement hydraulic pump driven by the internal combustion engine. An engine speed deviation is obtained from the difference between a target speed set by an accelerator operation of the internal combustion engine and an output speed thereof. Then a fuel injection target value in predetermined functional relation to the engine speed deviation, is obtained based on at least the engine speed deviation, and a fuel injection rate of the fuel injection pump is controlled based on the fuel injection target value. At the same time, a displacement volume target value of the hydraulic pump is determined based on at least the engine speed deviation and an actual discharge pressure of the hydraulic pump in such a manner that as the engine speed deviation increases an input torque of the hydraulic pump decreases, and the displacement volume of the hydraulic pump is controlled based on the displacement volume target value.

The control system has maximum speed setting device previously setting a first predetermined maximum speed and a second predetermined maximum speed higher than the first predetermined maximum speed for the operating speed of the variable displacement volume varying member and operative to select the first predetermined maximum speed when the direction of operation of the actuator commanded by the operating signal agrees with the actual direction of operation thereof, and select the second predetermined maximum speed when the position of the displacement volume varying member commanded by the operating signal is neutral or when the direction of operation of the actuator commanded by the operating signal is opposite to the actual direction of operation thereof. The pump control is constructed to effect the speed control of the displacement volume varying member based on the first or second predetermined maximum speed selected by the maximum speed setting device.

    摘要： An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values λa2, λb2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2. This structure shortens acceleration time during acceleration traveling and reduces braking distance during deceleration traveling while inhibiting vibrations of the electrically driven vehicle.
