摘要： There is provided an electric ground working vehicle including a left wheel and a right wheel, at least one caster, a working apparatus, an acceleration operating element for performing acceleration instructions, a turn operating element for performing turn instructions, and a control unit. The left wheel and the right wheel are independently driven by left and right electric motors respectively. The control unit controls a regenerative brake driving unit so that electric power is regenerated from the left and right electric motors to an electric power source unit when the acceleration operating element is not operated during traveling to regeneratively brake the left and right wheels. The control unit controls the brake force of the wheels so that the brake force of the wheel at the inside of a turn, among the left wheel and the right wheel, can be made greater than the brake force of the wheel at the outside of a turn when the acceleration operating element is not operated during traveling and turn instructions are inputted from the turn operating element.

摘要： A dual clutch transmission comprises a first clutch to be engaged for setting any one of forward-traveling odd-numbered speeds and a second clutch to be engaged for setting any one of forward-traveling even-numbered speeds. The dual clutch transmission establishes a desired forward-traveling speed by alternately engaging/disengaging the first and second clutches. A backward-traveling drive train is adapted to be driven by engaging one of the first and second clutches. When a reverse mode is established by a mode setting means, the one of the first and second clutches is engaged to drive the backward-traveling drive train by setting a speed change manipulator at a backward-traveling position, and the other of the first and second clutches is engaged to drive a fixed one forward-traveling speed drive train by setting the speed change manipulator at a forward-traveling position. While the reverse mode is established, the backward-traveling drive train and the fixed one forward-traveling speed drive train are kept activated regardless of whether the first or second clutch is engaged.
