According to the understanding of the design, the working principle of the smart balance car is called the principle of dynamic balance. This principle uses a motion compensation algorithm, uses its internal gyroscope and acceleration sensor to accurately detect small changes in the car body's attitude, and uses a sophisticated servo control system to sensitively drive the motor and make corresponding adjustments to maintain the entire car body. Stable and balanced.
At present, one-wheeled smart balance vehicles mainly achieve balance through three parts: smart chip controller, attitude sensor, and executive motor. In general, the overall principle of the balancing method of the balancing car is similar to that of drones and robots.
The operation of the balance car mainly relies on the dynamic balance principle related to its built-in sensors.
When the user tilts the body, the gyroscope and acceleration sensor will output corresponding posture information. After the controller senses this information, it commands the left and right motors to rotate in the corresponding direction. The gyroscope and acceleration sensor continuously measure the attitude of the vehicle at a certain frequency, and output attitude information to the controller. The controller constantly adjusts the rotation direction and speed of the motor, thus maintaining a dynamic balance.
Reports of safety accidents caused by balance cars are not uncommon.
The survey found that, like electric bicycles, smart balance bikes are driven by electric motors, so there is basically no sound during driving, and the speed is very fast, posing a great safety hazard to pedestrians in front, especially the elderly and children. Although many cities have formulated a number of restrictions on balancing vehicles on the road, related safety risks cannot be completely avoided.
