ABSTRACT:
An electric vehicle in which left and right electric motors respectively driving left and right transporting parts are controlled by a control part and particular turning control of the electric motors is carried out when the electric vehicle turns. The electric vehicle has a left and right pair of push-button turn switches. When one of the turn switches is operated, the control part selects a pattern from multiple preset deceleration patterns and decelerates the motor on the inside of the turn, which corresponds to the turn switch being operated, on the basis of this deceleration pattern. The electric vehicle makes turns and returns to straight-line travel optimally and smoothly and can be operated easily by an operator with no skill or experience.
