'Yang Jian' chip: a key breakthrough in NIO's intelligent driving system

According to news on September 21, NIO Auto held the NIO IN in Shanghai today. On the 2023 NIO Innovation and Technology Day, they officially released their first self-developed lidar main control chip - "Yang Jian". This chip is scheduled to start mass production in October this year, which will bring significant improvements to Weilai's intelligent driving system.

According to NIO's introduction, the "Yang Jian" chip is an important achievement of NIO's intelligent hardware team. It is equipped with a powerful 8-core 64-bit processor, which provides powerful computing support for lidar sensors. . In addition, it is equipped with an 8-channel 9-bit ADC with a sampling rate of up to 1GHz, which can efficiently capture the raw data of the lidar sensor and reduce power consumption by 50%

By optimizing the point cloud processing delay, the "Yang Jian" chip has demonstrated the powerful ability to process point cloud data up to 8 meters per second. At the same time, it also has the ability to receive dual input of raw data and point cloud data, providing better closed-loop iteration of data for the entire system, thus improving the accuracy and reliability of the sensing system. Another aspect of the "Yang Jian" chip An important feature is that it defines richer point cloud features, an innovation that further improves the accuracy and reliability of the perception system. The chip has an effective ROI coverage of 120 degrees horizontally and 9.6 degrees vertically. Coupled with 8 echo processing capabilities, the "Yang Jian" chip can support more complex and even harsh driving scenarios

In view of the point Cloud data processing is important to driving safety, and the "Yang Jian" chip will play a key role in the realization of vehicle anti-collision, early warning, lane departure and other safety functions. With the widespread application of "Yang Jian" chips, we have reason to believe that it will bring more innovation and improvement to vehicle safety systems
