Ningbo Yiheng Intelligent Technology Co., Ltd. successfully designed, developed and produced AI voice interactive control board system for smart cars. With the rapid development of intelligent network and voice control technology, the application of voice control in automobile driving is increasingly pursuing fast, safe and accurate, and intelligent voice AI assistants with learning ability have emerged as the times require.
In today's Internet of Vehicles industry, voice interaction relies more on cloud computing power processing and feedback, while data transmission between cloud-to-device and cloud-to-cloud-to-device invisibly produces more information delays, and in many network environments In an unsmooth scene, the dialogue feedback and operation speed of the intelligent voice AI assistant will be affected, resulting in incomprehensible, incomprehensible, and wrong answers.
In order to adapt to the human-machine communication that can be realized in different environments and situations, independent computing chips are required to meet the product requirements and the ability to process data. The car-grade chip used, recently, YHTECH Technology officially announced the success of tape-out of the industry's first car-grade full-stack voice AI chip. Create a full-stack in-vehicle voice solution integrating cloud, device and core.
Take the first AI car voice control board launched by YHTECH Intelligent Technology as an example. The micro-control unit in the control board mainly processes CAN bus information and control logic, ensuring that the control unit is compatible with the vehicle CAN bus protocol and vehicle wiring harness while running. And meet the EMC electromagnetic compatibility test, the chip, equipment and system placed in the electromagnetic environment will not be disturbed by the surrounding electromagnetic environment, to ensure that the normal operation of the equipment or system is not affected by the outside world.
Vehicle-grade control boards have very strict requirements on functions, reliability, and operating temperature, second only to military-grade chips in the fields of aerospace, weapons, and ships. Their operating temperature ranges from -40°C to 125°C. The definition of car-level is actually a set of hardware specifications. Those that meet the above standards can be called vehicle regulation grade.
YHTECH car-level intelligent AI voice control panel is online at all times. At present, most of the car-machine systems equipped with vehicles need to be connected to the network. For the recognition and processing of real-time voice information, from the driver's instruction to the receipt of the instruction and analysis and processing, the delay inherent in the cloud has a great impact on the acquisition, processing of real-time data and rapid response. Technical bottlenecks, users hope that the response speed of human-computer interaction is fast, and the computing power of the cloud is far from enough for in-vehicle products. Therefore, the Yiheng smart car-level intelligent AI control board increases the computing power of the edge side in the car-machine system. For example, when the car is driving in an uninhabited area or in a mountainous area, the signal cannot be fully received, so the computing power of the edge side is improved. Some deep learning engines can be made to operate locally. The basic design of the intelligent AI vehicle control panel meets the iterative upgrade and learning capabilities during the service period. At the same time, the car-grade chip can effectively protect the privacy of users. When users use some privacy functions, they are all operated by local computing power. It will not be uploaded to the cloud through the vehicle network. Therefore, the car-level intelligent AI smart chip control board facilitates the driver's barrier-free man-machine communication, increases calculation stability, solves the delay of the vehicle network, effectively releases the computing power of the main chip CPU, and improves the accuracy of speech recognition. The clarity and response speed of the navigation map, and the in-vehicle entertainment information can be read more quickly.
Speech recognition is a very important function in the smart car system. It seems very difficult from a technical point of view to realize local speech recognition without network data. Yiheng Technology Company said: "We input part of the speech recognition information locally. For example, practical functional instructions such as opening car windows and air conditioners. In addition, information such as weather forecasts, stocks, and news can also be queried offline. How to realize offline real-time information such as our regular and immediate information? Take weather forecasts as an example. The weather in a day is changeable, so the real-time weather is not necessarily accurate. When the system is connected to the network, the weather information is cached as forecast data. The same is true for other information using the cache. After the relevant information is updated, the car system will Actively update data through the network".
