The working principle of the electric balance car is that the system uses the attitude sensor (gyro, accelerometer) to monitor the pitch state and state change rate of the body, and after the appropriate data and instructions are calculated by the high-speed microcontroller, the motor is driven to move forward or backward. Acceleration to achieve the effect of front and rear balance of the car body.

Take the longitudinal axis of the overall center of gravity of the driver standing on the vehicle and the vehicle as the reference line. When this axis is tilted forward, the built-in electric motor in the body will generate forward force. On the one hand, it balances the torque of the person and the car falling forward, and on the other hand, it generates acceleration for the vehicle to move forward. On the contrary, when the gyroscope finds When the driver's center of gravity is tilted backward, the backward force will also be generated to achieve a balance effect. Therefore, as long as the driver changes the angle of his body to lean forward or backward, the electric balance car will advance or retreat according to the tilt direction, and the speed is proportional to the degree of the driver's body tilt.

In principle, as long as the power is turned on correctly and sufficient power can be maintained, the people in the car do not have to worry about the possibility of tipping and falling. This is completely different from vehicles such as scooters that generally need to be balanced by the driver.
