Electric balance car, also called somatosensory car, thinking car, camera car. There are mainly two types of unicycle and dual-wheel in the market. Its principle of operation is mainly based on a basic principle called "Dynamic Stabilization" (Dynamic Stabiliza- tion), which utilizes the gyroscope and acceleration sensor inside the car body to detect changes in the attitude of the car body and to use a servo control system. Drive the motor precisely to adjust accordingly to maintain system balance.
The principle of operation is based on a basic principle called Dynamic Stabiliza- tion, which is the auto-balancing capability of the vehicle itself. The built-in precision solid-state gyroscopes are used to determine the posture of the vehicle body. After a precise and high-speed central microprocessor calculates an appropriate command, the motor is driven to achieve a balanced effect.
Most of the early stage of the market is using ST's MCU as the main control core of the balance motor control board, because ST design in this industry in earlier. TI also introduced C2000 series DSP master chips for balanced cars, which are more stable in performance than ST's MCU, lower power consumption, faster processing speed, and no jitter when the balance car is walking at a low speed or standing. TI's TI plans to promote the C2000 series of main control platform solutions on the balance car, and China Power Grid Information Technology Co., Ltd. is fully responsible for advancing the work.
In January 2015, China Power Grid Information Technology Co., Ltd. was designated by TI to be responsible for the full development of the balance car customers. After nearly five months of customer development, a total of 1,000 customers were involved in the balance car and the final confirmation of the production of balance car customers. A total of 437 companies, but of these 437 balanced car customers, there are a total of 102 customers with truly independent research and development capabilities, while the other 335 are buying back control panels and then assembling and selling finished products. For customers with research and development capabilities, the main push TI's C2000 series of main control platform and TI power management chip, as well as TI's Bluetooth and wireless chips and other related electronic components can be used in the balance car. For those who do not have research and development capabilities, buy a balance car customer for the control board, and then directly recommend the control board or plan that the R&D-capable customer has already designed to the customer who buys the board. This is equivalent to selling the board while selling the TI. The chip, with the customer to achieve double vision.
Finally, attach the schematic diagram of the balance motor control board and the physical map of the control board that has been successfully developed:
