Electric balance car, also called body sense car, thinking car, camera car, etc. There are two categories of unicycle and double wheel on the market. Its operation principle is mainly based on a basic principle called "dynamic stability" (Dynamic Stabilization).
The gyroscope and acceleration sensor inside the car body are used to detect the change of the car body posture, and the servo control system is used to accurately drive the motor and adjust it accordingly to maintain the balance of the system. It is used as a means of transportation, leisure and entertainment of a new type of green environmental protection products.
With the strengthening of people's environmental awareness, the number of electric vehicles is increasing day by day. At the same time, scientists have finally developed a new two-wheel electric balancing vehicle. Two-wheel electric balance car is a new type of transportation vehicle, which is different from the electric bicycle and motorcycle wheels arranged front and back way, but uses two wheels fixed side-by-side way. Two-wheel electric balance vehicle uses two wheels to support, battery power supply, brushless motor drive, coupled with single microcontroller control, attitude sensor acquisition Angle speed and Angle signal, jointly coordinate and control the balance of the car body, only relying on the change of the body center of gravity can achieve the vehicle start, acceleration, deceleration, stop and other actions.
Electric balance vehicle system often uses a brush DC motor or brushless DC motor, Brush motor is characterized by fast starting, sensitive braking, a large range of smooth speed adjustment, simple control circuit, Suitable for the general power equipment, Can work continuously for 5,000 hours, Regular life span of two to three years, But for 1000 hours, Carbon brush required; brushless motor is integral motor and drive, Without replacing the electric brush, A mechatronics equipment, Can continuously run 20,000 hours of routine life of seven to ten years, Digital frequency conversion control speed control is easier, It consumes a third of the power of a brush motor, However, the high cost requires a relatively high control accuracy, Suitable for the equipment with relatively high speed control requirements.
