"The annual CES (International Consumer Electronics Show) is about to open in Las Vegas. Qualcomm held a press conference the day before the official opening. Unlike in the past, Qualcomm has spent a lot of time on mobile phone chips, leaving more time on the stage for automotive related content.
More than 30 5g devices will be available this year, most of them smartphones
Before that, let's take a look at the short content related to mobile phones.
At the press conference, Qualcomm said that at present, the company has obtained more than 30 5g terminal devices, most of which are smartphones equipped with Xiaolong 855 mobile platform and Xiaolong X50 5g modem series from Global OEMs.
This sounds more than the first batch of 4G devices launched in 2011. According to the list of OEM partners revealed by Qualcomm on 5g last year, it should include 18 mobile phone manufacturers such as ASUS, Nokia (HMD), HTC, LG, Sony, vivo, oppo and Xiaomi.
Qualcomm Xiaolong 855 is the first mobile platform launched by the company for 5g commercial terminal equipment. According to Qualcomm, the terminal equipment equipped with Xiaolong 855 can support both below 6GHz and millimeter dial-up frequency band in combination with Xiaolong X50 5g modem and Qualcomm RF front-end solution, so as to realize thousands of megabits connection rate and low delay.
The third generation Xiaolong automobile digital cockpit Series platform
At the press conference, Qualcomm launched a new generation of Xiaolong automobile digital cockpit Series platform (Qualcomm) ® Snapdragon ™ Automotive cockpit platforms), which covers chips, a series of wireless connection functions (4G / 5G, Wi Fi, Bluetooth, etc.) and some software functions, aims to improve the in car experience and meet the higher-level computing and intelligence needs of the next generation.
According to Qualcomm, the new generation of Xiaolong automobile digital cockpit Series platform is based on the technical basis of Xiaolong 820a platform, supports immersive graphics and image multimedia, computer vision, AI and other functions, has heterogeneous computing functions, and integrates artificial intelligence engine and tensor accelerator HTA (hexagon tensor accelerator) for AI computing.
It can realize, for example, the experience of intelligent AI assistant, the interaction between cars and people, various situational security application examples, etc. the whole experience of Xiaolong automobile digital cockpit platform includes:
Highly intuitive AI experience: support personalized settings of drivers and passengers, in vehicle virtual assistant, natural voice control, language understanding and adaptive man-machine interface
Situational safety: for intelligent driving assistance system, including in vehicle monitoring and ultra-high definition look around monitoring
More intelligent navigation: support vision assisted positioning and multi frequency GNSS Lane level navigation to realize augmented reality based navigation system
Rich visual experience: support multiple displays in one vehicle, including ultra wide panoramic display, reconfigurable 3D digital dashboard, augmented reality head up display (HUD) and ultra-high definition media streaming
Immersive audio: provide excellent audio experience, including personalized multi sound zones customized for each user, clear in car conversation, and active noise reduction and echo cancellation with engine noise suppression
This time, Qualcomm will divide the platform into three levels according to different positioning, including performance series for entry-level, premiere series for midrange and paramount series for Supercomputing platform, so as to provide different levels of computing power and functions. According to Qualcomm, the new generation of Xiaolong automobile digital cockpit Series platform (subordinate to the third generation) has modular architecture design and can provide diversified solutions according to the needs of automobile manufacturers.
AI vehicle experience display based on Amazon Alexa
Qualcomm also uses the language processing and speech recognition functions provided by Amazon Alexa to create the on-board experience of the next generation of vehicles based on artificial intelligence technology, such as natural interaction between vehicles and drivers, interaction between on-board systems and passengers, etc.
As part of the on-board experience demonstration, the on-board system also integrates services such as Amazon music, prime video, fire TV and audible. Basically, relying on natural voice commands, people in the car can interact with the car to realize the required entertainment and car auxiliary functions such as navigation.
According to Qualcomm, the smart audio platform behind it provides the basis for the Alexa voice service (AVS) development kit launched in 2018. It can provide real-time wake-up word monitoring, achieve high response and accurate voice activation, and significantly improve the car experience. In this regard, nakul duggal, senior vice president of product management of Qualcomm, said:
The vision behind these Qualcomm automotive solutions is to continuously improve and expand the possibilities of the in car experience, and it is also a solution to provide drivers with safety awareness.
C-v2x technology enables the vehicle to have independent communication capability
For a long time, automobile manufacturers have been talking about how to make cars have communication ability, so that vehicles running on the road can collect enough information, so as to reduce the probability of traffic accidents.
In this regard, Qualcomm has introduced a new c-v2x (cellular vehicle to everything) technology, which aims to enable cars to have autonomous communication capability. It is based on cellular radio communication technology, but it can operate without using cellular network and relying on base station and server communication.
Ideally, Qualcomm hopes that cars, traffic lights and zebra crossings running on the road are equipped with corresponding chips. In such a scenario, vehicles can sense the information on the road, so as to achieve safer travel, improve road traffic efficiency, and even lay the foundation for automatic driving.
According to nakul duggal, senior vice president of product management of Qualcomm, c-v2x technology does not have the initiative in a sense. It will not suddenly brake your car, but will only remind owners at critical moments.
It is understood that Qualcomm will try c-v2x technology with the regional transportation committees of Las Vegas and South Nevada, while automobile and motorcycle manufacturers such as Audi, Ford and Ducati will participate in the on-site demonstration, and the subsequent test will be carried out in other countries and regions.
