Self-stabilizing vehicle and control method thereof
A self-stabilizing vehicle includes a mass gyroscope which is fixed at an occupant compartment chassis corresponding to a portion where occupants sit. The occupant compartment portion may tilt outwards in response to the centrifugal force. If the vehicle has three or more wheels, the load is evenly distributed on the left wheel and the right wheel which move oppositely up and down about an effectively centrally-mounted shaft pin. Further, the present disclosure proposes a method for operating the self-stabilizing vehicle. According to the self-stabilizing vehicle and the operating method thereof, a vehicle having a narrow body may be used. When the vehicle undergoes external forces such as the centrifugal force and the crosswind, the occupant compartment can maintain the vertical stability even though the wheels may slide sideways.
