<p>PROBLEM TO BE SOLVED: To improve the endurance of parts by controlling a drive power only when needed by interrupting a control of the drive power when all the wheels are in deceleration state and a drive wheel is set at a value less than the threshold value on the basis of the single body speed estimated value of the vehicle speed detected value to be free of control of driving power. SOLUTION: Wheel speed sensors 7FL through 7RL are attached on each of the wheels 1FL through 1RR as wheel speed detecting means for outputting a wheel speed signal comprising a sine wave of a frequency corresponding to a rotation speed of these wheels. Then, each of the detection signals of each of the wheel speed sensors 7FL through 7RL and a strap lamp switch 8a is input to the controller 31, which detects that all the wheels are set in a deceleration state, and each of the wheel speed sensors 7RL and 7RR sets a value less than the threshold value on the basis of the vehicle body speed estimated value of the wheel speed detected value of the drive wheel 1RL and 1RR to set the drive power in the state of non-control state at which time, the control of the drive power. Thus, the endurance of the parts can be improved.</p> |
