The reason why BYD does not use domestic chips may be:
Byd has been self-developing related chips, such as IGBT chips, car-level MCU chips, analog IC chips, etc., but before BYD put more energy into the technology improvement of new energy vehicles, and did not pay too much attention to the field of intelligent driving, so BYD has not invested too much money and energy in autonomous driving chips.
Byd cars require processors that prioritize safety over functionality, so they don't use high-end processors. The pursuit of the car is safety first, function second, high-end processors are too pursuit of function, often security is not as good as low-end processors.
Byd does not use domestic chips may be because the technical level and stability of domestic chips still need to be improved, and there is still a certain gap compared with the international leading chip manufacturers. In order to ensure the quality and performance of its products, BYD chooses to use products from internationally renowned chip manufacturers. In addition, the technology and service capabilities of international chip manufacturers are more mature and reliable, which can better meet the needs of BYD products. Therefore, BYD's choice not to use domestic chips is also due to product quality and user experience considerations.
As a Chinese automaker, BYD has been committed to technological innovation and improving product quality. Although domestic chips have made great progress in recent years, in the automotive field, the requirements for chips are more demanding, and they need to have higher stability, reliability and performance.
Therefore, in order to ensure the quality and performance of the products, BYD may choose to use foreign chips to ensure the stability and reliability of the vehicles, but also to remain competitive in the global market.
