Operating device for electric vehicle
An operating device of an electric vehicle enables an electric vehicle to be operated, the electric vehicle having: left and right driving wheels; and left and right driving motors respectively independently driving these left and right driving wheels. The operating device has: a joystick operable to move so as to issue a turning direction instruction of the vehicle; and a traveling instruction portion issuing a traveling instruction of the vehicle by operation different from movement operation of this joystick. The joystick has a grip operable to be gripped by an occupant of the vehicle. By making a difference between rotating speeds of the left and right driving motors based on a combination of the turning direction instruction of the joystick and the traveling instruction of the traveling instruction portion, a gentle turn or a pivotal brake turn of the vehicle is performed.
