Detailed explanation of the principle of monitoring of balanced vehicle sensors
It is understood that the working principle of smart balance car is called the principle of dynamic balance. This principle uses a motion compensation algorithm, which uses its internal gyro and acceleration sensors to accurately detect small changes in the attitude of the vehicle body, and uses a precise servo control system to sensitively drive the motor and adjust accordingly to maintain the entire body of the vehicle. Stability and balance.
At present, the unicycle smart balance car mainly achieves balance through three parts: a smart chip controller, an attitude sensor, and an electric motor. In general, the overall principle of the balancing method of a balanced car is similar to that of drones and robots.
The balance of car operation mainly depends on the dynamic balance principle associated with its built-in sensors.
When the user tilts the body, the gyroscope and the acceleration sensor will output the corresponding posture information. After the controller senses this information, the two motors are commanded to rotate in the corresponding directions. The gyroscope and the acceleration sensor continuously measure the attitude of the vehicle at a certain frequency and output the attitude information to the controller. The controller constantly adjusts the rotation direction and the rotation speed of the motor, thus maintaining a dynamic balance.
It is not uncommon for safety accidents caused by balancing vehicles to be reported.
The survey found that, like electric bicycles, smart balance cars, driven by motors, have almost no sound during driving, and the speed is very fast. This poses a great potential safety hazard for pedestrians in front of them, especially for the elderly and children. Although many cities have established a number of restrictions on the balance of vehicles on the road, they still cannot completely avoid the related security risks.
