Abstract:
1. A differential steering type motorized vehicle comprising a pair of right and left drive wheels which are located at an central position between a front wheel and rear wheels, and drive-controlled so as to perform differential steering caused by differences in rotational direction and rotational speed between the drive wheels, wherein the rear wheels are a pair of right and left omnidirectional wheels, and the front wheel is one wheel which is supported by a lower end of a handlebar shaft provided below handlebars and located at a central position in the lateral axis direction, and further comprising: a rotational position sensor for detecting a turn direction and a turn angle from the reference position of the handlebars to be turned in the right or left direction; and a motor drive wheel control means for driving motors attached to the pair of right and left drive wheels by controlling the rotational direction and the rotational speed in response to a detection signal of the rotational position sensor so that the drive wheel on the handlebar turning direction side is successively decelerated, stopped, and accelerated in the reverse direction with respect to the drive wheel on the opposite side as the turn angle is increased, and rotates in the reverse direction at a same speed to each other at a turn position of 90°.
