[0067] A balancing method of a two-wheeled electric vehicle, comprising the following steps:

[0068] When driving at high speed, the front wheel automatic steering machine 1 adjusts the automatic steering of the front wheel 3 through the roll data of the vehicle body support 5 collected by the gyro stability controller 2, and the centrifugal force during steering is actively inhibited through the roll of the vehicle body;

[0069] When driving at low speed, the rear wheel automatic steering machine 6 adjusts the automatic steering of the rear wheel 4 through the roll data of the vehicle body support 5 collected by the gyro stability controller 2, and the rear wheel steering has less influence on the roll angle than the front wheel 3, so it is suitable for steering at low speed to maximize the steering flexibility.

[0070] The balancing principle of the two-wheeled electric vehicle according to the present application through speed is as follows:

[0071] The front wheel 3 and the rear wheel 4 are powered wheels with built-in hub motors, and the gyro stability controller 2 automatically allocates power to the front wheel 3 and the rear wheel 4 according to the driving condition to keep the driving stable at any time.

[0072] Specifically, the push mode is started when accelerating, the driving torque of the front wheel 3 and the rear wheel 4 is the same, and the force is exerted at the same time; the pull mode is started when driving stably, the driving torque of the front wheel 3 is greater than that of the rear wheel 4; the rear wheel driving or dragging mode is started when decelerating or braking, the braking force of the rear wheel 4 is greater than that of the front wheel 3 or the driving force of the rear wheel 4 is greater than that of the front wheel 3.

[0073] The balancing principle of the two-wheeled electric vehicle according to the present application through steering is as follows:

[0074] As Figure 6 shown, when the vehicle body is tilted to the right by external force or internal gravity center change, the gyro stabilization controller 2 detects the change of the tilt angle and issues a command to make the first steering motor 11 of the front wheel automatic steering machine 1 turn right, so that the geometric center 92 of the two-wheel electric vehicle swings to the left to cross the ground center line 91, until the left tilt of the gravity center crosses the ground center line 91 to generate a yawing moment, so that the vehicle body stops continuing to tilt to the right; the ground center line 91 refers to the shortest line between the contact points of the front wheel and the ground and the contact points of the rear wheel and the ground, and the geometric center 92 refers to the geometric center point of the vehicle body when the battery basket is in the middle in the natural and stationary state.

[0075] As Figure 7 shown, the gyro stabilization controller 2 detects the change of the tilt angle and issues a command to make the second steering motor 61 of the rear wheel automatic steering machine 6 turn left, which makes the geometric center 92 swing to the left to cross the ground center line 91, until the left tilt of the gravity center crosses the ground center line 91 to generate a yawing moment, so that the vehicle body stops continuing to tilt to the right.

[0076] The gyro stabilization controller 2 detects the change of the tilt angle and issues a command to make the third steering motor 71 of the battery pack basket automatic adjuster 7 turn left, which makes the geometric center of the battery pack basket 8 swing to the left to cross the ground center line, until the left tilt of the gravity center of the whole vehicle crosses the ground center line to generate a yawing moment, so that the vehicle body stops continuing to tilt to the right.

[0077] When the vehicle body is tilted to the left by external force or internal gravity center change, the opposite direction movement is performed to make the vehicle body stable.
