Taking a four-wheel automobile as an example, the central point of the line segment corresponding to the respective axes of the two front wheels is a, and the central point of the line segment corresponding to the respective axes of the two rear wheels is B. The straight line where AB is located is one of the central axes of the vehicle, the central point C of the AB line segment is used as a straight line CD perpendicular to AB at the point C, and the AB straight line and the CD straight line are respectively horizontal to the ground.

No matter the current situation that the four tires 81 of the vehicle are all towards the AB direction, when the mode of 'all tires synchronously control the direction at the same time' on the operation panel 6 is adopted, the directions of the four tires 81 can be all unified and consistent in real time only by modulating the direction control keys on the operation panel 6, or more intuitive control can be realized through the shaking handle with the sensor. For example, the tires 81 may all be oriented parallel to the CD line, and then driving each tire 81 at the same rate achieves parallel movement of the vehicle, the direction of movement being perpendicular to AB.

Regardless of whether the four tires 81 of the vehicle are oriented in the direction AB, when the "direction control for each tire" mode is performed on the operation panel 6, the rotation of the vehicle in the horizontal direction by 360 degrees at the home position can be realized when the driving motor 3 of one tire 81 is driven or when all the tires are driven, when the direction of each tire 81 is adjusted to be identical to the tangential direction of the circumscribed circle O (with the point C as the center) by the circumscribed circle O of the rectangle in which the axes of the four tires 81 are located.

When the vehicle goes up a slope, the rotating motor 5 controls the direction of the telescopic arm 11 of each tire 81 to be consistent with the direction of gravity, and then controls the telescopic arms 11 of the two rear tires 81 to extend to increase the distance between the rear vehicle body and the ground, so that the vehicle body is kept horizontal in the process of going up the slope to increase the riding comfort. The same goes for downhill.

The invention effectively monitors the power system of the vehicle and transmits the monitoring information to the operation panel, so that a user or an intelligent automatic system can make a corresponding instruction according to the state information and road condition information of each tire, accurately control the direction and speed of each tire and achieve intelligent automatic safe driving.
