    摘要： Wheel drive motors (8) constituted of electric motors for driving rear wheels (7) are provided on a vehicle body (2) of a dump truck (1). Each wheel drive motor (8) is connected to a main power generator (12) through a bidirectional converter (20) and the like and driven by power supplied from the main power generator (12). A resistor (21) that consumes regenerative power from each wheel drive motor (8) is connected to the bidirectional converter (20). Cooling air is supplied to the resistor (21) from a blower (24). Operations of a switch (23) of the resistor (21) and the blower (24) are controlled by a controller (28). A mode selecting switch (29) for selecting a heating mode (A), a blowing mode (B), and a heating and blowing mode (C) is connected to the controller (28).

    摘要： Provided is an electrically driven vehicle that is capable of suppressing drive wheel slippage without increasing the pitching vibration of the vehicle. The electrically driven vehicle having electric motors (1, 4), drive wheels (3, 6) driven by the electric motors respectively, and, when at least one of the drive wheels slips, an electric motor control device (40) for reducing the torque of at least one of the electric motors that drives the at least one wheel slipped, and for restoring the torque of the at least one electric motor when the slippage is stopped includes a pitching detection device (26) for detecting the amplitude of pitching vibration to which the vehicle is subjected. The amount of torque of the at least one electric motor to be restored by the electric motor control device over a predetermined period of time after the slippage is stopped varies depending on whether or not the amplitude A detected by the pitching detection device is greater than an assessment value A1.

    摘要： A vehicle which evaluates tire wear properly even in a road condition that tires easily slip or lock up. The vehicle, which has a driven wheel and a driving wheel with tires attached thereto, includes: a revolution speed detector for detecting revolution speeds of the driven and driving wheels; a wheel speed detector for detecting wheel speeds of the driven and driving wheels based on the detected revolution speed data of the driven and driving wheels; a wheel speed ratio detector for detecting a wheel speed ratio between the driven and driving wheels based on the detected wheel speed data of the driven and driving wheels; and a tire condition evaluator for outputting an evaluation result indicating that the tire(s) attached to the driven wheel and/or driving wheel is(are) worn when the wheel speed ratio is higher than a preset threshold.
