Abstract

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.

Claims (7)

1. A self-stabilizing vehicle, comprising an occupant compartment, a chassis of the occupant compartment, a drive unit and a brake unit, a stabilizing unit comprising a parallelogram structure and at least one pair of wheels,

wherein the chassis of the occupant compartment is fixedly provided with a mass gyroscope, the mass gyroscope has a stabilizing ability and is switchable; and the chassis of the occupant compartment is further fixedly provided with an electronic gyroscope;

wherein when the vehicle is in a static state or when the vehicle moves in a straight line, a load of a weight of the vehicle is evenly distributed on a left axle and a right axle of any pair of the wheels under any tilt angle of a road surface;

wherein the parallelogram structure is provided with a first cylinder mechanism disposed on a left side of the parallelogram structure and a second cylinder mechanism disposed on a right side of the parallelogram structure, wherein each of the cylinder mechanisms is connected to the parallelogram structure on opposing parallel sides forming a parallelogram of the parallelogram structure, wherein each of said cylinder mechanisms is composed of a respective stabilizing air cylinder that is mounted on or connected to a respective shock absorbing air cylinder or a respective spring, and each of the cylinder mechanisms further includes a respective detector to indirectly detect a stress situation of the left axle and the right axle.

2. The self-stabilizing vehicle according to claim 1 , wherein the stabilizing air cylinders at the left side and the right side are interconnected through a liquid pipe to provide an effective stabilizing lever seesaw effect for the two wheels at the left side and the right side, and all of the stabilizing air cylinders are connected to an adjusting system to meet requirements of different gravities and different driving states, wherein the requirements include a height of the occupant compartment, and a response speed and a strength of a shock absorbing unit and the stabilizing unit.

3. The self-stabilizing vehicle according to claim 1 , wherein the parallelogram structure comprises a left parallelogram and a right parallelogram, and each of the left parallelogram and the right parallelogram is provided with an electronic gyroscope; the stabilizing air cylinders comprise a left stabilizing air cylinder and a right stabilizing air cylinder, and at least one microcontroller is configured to control the left stabilizing air cylinder and the right stabilizing air cylinder.

4. The self-stabilizing vehicle according to claim 2 , wherein an electric part of the stabilizing unit is optionally turned off during driving of the vehicle.
