<p><P>PROBLEM TO BE SOLVED: To provide a differential steering type electric vehicle whose front wheel can be steered directly by rotating operation of a handle and which can be rotated at the place with the intermediate position of a vehicle body as the center while performing differential rotation type control of driving vehicles. <P>SOLUTION: Rear wheels 3L and 3R are a pair of right and left free-direction wheels, and the front wheel 1 is one wheel supported by the lower end of a handle shaft 21 provided under the handle 20 and positioned in the middle of a right and left direction. The differential steering type electric vehicle is provided with: a potentiometer 25 which detects a rotating operation direction and a rotating operation angle from the reference position of the handle 20 rotate-operated to the right and left; and a motor driving wheel control means which drives motors respectively attached to the pair of right and left driving wheels 2L and 2R by controlling a rotating direction and a rotating speed in response to the detection signal of the potentiometer 25 so that the driving wheel 2L or 2R on the operating direction side of the handle 20 may be decelerated, stopped and invert-accelerated in order with respect to the driving wheel 2R or 2L on the opposite side with the increase of the rotating operation angle, and may be inverted at equal speed at a rotating operation position of 90°. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
