    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： 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.

    摘要： The invention provides an active mass damper by use of which a machining apparatus can be downsized. The active mass damper includes a support unit for supporting a weight movably and horizontally, a motor for driving the weight, and a controller for controlling the motor. A torque command signal to be given to a motor of an X-table and a torque command signal to be given to a motor of a Z-table are put into the controller of the active mass damper so that the motor for driving the weight can be driven by feed-forward control using the torque command signals and feedback control based on the displacement of the weight.
