Abstract: This article invites industry leaders and market-adjusting companies to talk about technology trends and new solutions for ADAS or V2X that companies are concerned about. This article refers to the address: http:// CCID Consulting: Although the domestic auto industry is huge, the level is low. Han Xiaomin, an analyst at CCID Consulting's Semiconductor Industry Research Center: Although China's auto industry is large, the overall market level is still low. From a technical point of view, the current ADAS system has been mature in bicycle-based applications, such as adaptive cruise control, while autopilots and car networking are still in the technical field, mostly from groping and trial, from mature markets. There is still a distance in the application; from the market level, the ADAS system based on improving vehicle safety and comfort will have a faster development, and the application of V2X, especially in the V2I field, is limited to the current consumption level, infrastructure level and related. Restrictions such as laws and regulations will be quite lagging in market applications. IHS: ADAS attracts attention in the driving force of future automotive electronics development In the past 2014, China’s total auto semiconductor revenue was $5.5 billion. IHS expects revenue to climb to $6.2 billion in 2015, compared to 11% in 2014, with 10% growth in powertrain, automotive infotainment systems and body/ Convenient electronic systems will be the main contributors to this market. Although China's auto sales growth will gradually decrease in the next few years, the pursuit of energy efficiency and green energy, higher security and better driving experience will enable more and higher performance semiconductors in the next few years. Requires application in a car. High-performance engines, including safe ADAS applications, automotive entertainment and comfort electronics, will require more controllers, network connections, driver ICs and sensors. Over the next five years, IHS expects the fastest growth in sensor chips – 14% CAGR, followed by microcontrollers and analog ICs. Among the driving forces behind the future development of many automotive electronics, ADAS is compelling. ADAS technology is seen as the only way to future automated/semi-automatic driving. In the most recent phase, the application of ADAS will also bring safety and comfort to the driver, while at the same time making the power system more efficient. The current use of ADAS in the market is mainly concentrated in high-end cars such as BMW and Mercedes. Some domestic manufacturers have also introduced such as LDW, BSD, and surround view in some high-end models. Considering cost and technology maturity, IHS believes that some applications based on camera sensor will develop rapidly in recent years, such as looking around for automatic parking and forward monitoring. Broadcom: ADAS and HEV/EV are the fastest growing in automotive technology trends Internet of Vehicles (IoV) consists of two parts. The first part is to solve the interior interconnection through wired connection, and the second part is to solve the task of communication between tablet, wearable and other vehicles through wireless connection. From the trend of the entire automotive technology, the fastest growth is two large blocks (Figure 1), the first is ADAS (Advanced Driver Assistance System); the second is HEV / EV (hybrid / pure electric vehicle) . Car Ethernet is mainly based on people and cars because it is very suitable for the backbone of the car. The vertical axis data shown in Figure 2 refers to the number of Ethernet nodes carried on the car. It is expected that more than 100 million Ethernet nodes will be used in a moving car by 2019. And in 2021, it quickly grew to 200 million. In terms of wireless connection, according to the left side of Figure 3, the wireless connection modes in the car are divided into four categories. The first category is traditional Bluetooth headset communication; the second category is relatively new is in-vehicle Wi-Fi/BT; the third category is NFC (Near Field Communication); the fourth category is more familiar GPS. The right side of Figure 3 is the growth rate. Why is NFC having a very high growth rate? The main reason is that today's NFC application in the car is basically zero, so the compound growth rate is very high. In addition, although we see that 60% - 70% of cars are equipped with GPS and Bluetooth as standard, the combined sales of Wi-Fi and Bluetooth (BT) currently have a lower share. So in the next five or six years, Wi-Fi and Bluetooth chip growth rates are very high in the entire automotive sector, with a compound annual growth rate of nearly 40%. In the car, four wireless domain connections are mentioned in the front, and LTE is the most important part of the networking in the car network. Various wireless technologies can be widely used in various parts of the vehicle body to achieve different functions: for example, V2V is the communication between the vehicle and the vehicle, and V2I is the distribution between the vehicle and the traffic management system; including the use of a key, similar to a Bluetooth key, The concept of NFC keys provides car networking products, including other FM Wi-Fi, including GPS, a conventional satellite positioning function. Dr. Ali Abaye, Senior Director, Auto Network and Physical Layer Products, Broadcom: We believe Wi-Fi will grow at 8x in the car, mainly because Wi-Fi is basically on mobile phones and consumer electronics. Becoming a standard, in fact, this is the trend. One way is to realize multi-screen interaction through Wi-Fi. For example, if you have pictures or videos on your mobile phone and want to share them with others, you can use your mobile phone or tablet to connect with the central control system on the car, and upload the information to P2P or through the media. The second way is that everyone is more familiar with the home wireless router, and the whole car is installed as a hotspot, so that the car device can connect to the network through WiFi. Most cars can now be equipped with a Bluetooth phone, which can be called from a mobile phone or through a car phone on the car. The Bluetooth (BLE) system mentioned here, especially the low-power Bluetooth system, is more suitable for interaction between the wireless wearable device and the car. Regardless of China or the United States, everyone pays attention to monitoring the safety of drivers inside the car. If there is an emergency that can cause a major accident, with a BLE4.0 or BLE low-power system, it is easy to monitor the driver's condition through the wearable device. The vehicle can be braked or some other deceleration operation through the Ethernet ADAS system in time to avoid vehicle accidents. Broadcom provides the technology needed for a complete set of car networking, including wired Ethernet technology, wireless Wi-Fi, GPS, Bluetooth, NFC and other wireless technologies, which can greatly improve the progress of the Internet of Vehicles. At the wired end, Broadcom introduced BroadR-Reach, whose core is to achieve 100Mbps data through a single pair of twisted pair cables, mainly to solve the relevant signal processing on the physical layer, ie, the transmission medium, and all the car-based Ethernet in the Layer 2 or higher protocol. The protocol stack is the same as that used on mobile phones and computers, so there is no need to worry about what network to use for the underlying development when developing programs. At the end of 2013, the BMW X5 SUV became the first model to use BroadR-Reach automotive Ethernet technology, which uses BroadR-Reach Ethernet to form a surround view system. Regarding the driverless system, on the one hand, it is necessary to match the data based on the ADAS model provided by the Ethernet, and on the other hand, the GPS needs to provide the position data, and some very good algorithms are needed in combination to realize the unmanned function. Renesas: The application of ADAS helps to achieve autonomous driving or driverless driving ADAS is currently a hot and fast-developing automotive application. ADAS systems can be divided into two categories: high-speed applications are mainly integrated into ECUs (electronic control devices) through sensors (such as radar) and smart cameras; low-speed applications are The camera collects relevant information to the ECU, which is the 360° panoramic viewing system. As automakers become more demanding on security encryption and functional security. Driver assistance systems have been used in automotive safety systems and are becoming increasingly sophisticated. The application of ADAS will contribute to the growth of the company's future business and ultimately achieve autonomous driving or driverless driving. The key to implementing an ADAS system is that it is closely related to semiconductors, from sensors to cameras to ECUs. In particular, it has extremely high requirements for its high performance, high speed, large capacity, low power consumption and safety functions. Lin Zhien, Vice Minister of Automotive Electronics, Renesas Electronics Application Technology Center: Renesas Electronics' SH7766 solution is a 360° panoramic viewing system for ADAS systems. The SH7766SoC integrates multiple hardware engines and is equipped with 2D graphics and optional Equipped with a 3D graphics engine function, it can stack high-precision graphic elements on the camera video, which can form a more advanced user interface. Infineon: Focus on car networking security Automotive technology innovation is inseparable from semiconductors, and semiconductor technology must be at the forefront. Infineon has already started market research and new product development in automotive intelligence. There are four major links in the application of automotive safety technology. From the identification, prediction, prevention and protection, in the first three links, the ADAS system is essential to prevent accidents, improve vehicle safety, and increase driving. Comfort. In recent years, in the advanced assisted driving system ADAS, the three technologies of adaptive cruise control system (ACC), lane departure warning (LDW) and side object detection (SOD) are currently growing rapidly. The implementation of ADAS's functions is based on different sensor technologies and relies on a highly integrated, high-security information processor. Xu Hui, Senior Director of Automotive Electronics Business, Infineon China: Traditionally, the car is a closed system. The realization of the car network makes the car an open system, which makes it easier to upload and download various data and information. However, due to the disclosure of information, it also brings the risk of hacking. The security of the Internet of Vehicles, or data security, is the focus of Infineon. The Internet of Vehicles includes car and car, car and infrastructure, car and cloud, and the integration of cars and consumer electronics such as smart phones and tablets. The application scenarios are very wide, such as predicting traffic congestion and accidents, Internet services, Payment services, emergency calls, repair site services, software upgrades, remote diagnostics, and more. Any channel that is maliciously invaded, data is abused or stolen, viruses, etc., will bring immeasurable losses to vehicles and personal safety. Xilinx: Car camera systems have become an important differentiating factor In today's automotive market, government safety standards require the latest and most intelligent safety systems, such as the US's backup camera and the European NCAP's Automatic Electronic Brake System (AEB). For OEMs using Advanced Driver Assistance Systems (ADAS) technology, in-vehicle camera systems have become an important differentiator. The complexity of the ADAS system architecture is increasing, requiring: visual systems need to display video processing (such as image enhancement and distortion correction) and graphical information overlay to the driver; non-visual systems require image processing analysis; motion estimation The deep analysis capabilities used to describe the vehicle environment support continuous threat assessment and driving countermeasures. Now, the software code in a car system may reach hundreds of millions of lines, and the programmable electronic platform is undergoing a new revolution. The connection and interaction, understanding and communication between the car and the people represented by ADAS and V2X are the next frontier. The goal is to make the vehicle users safer, get timely and effective information, improve efficiency and enjoy the body and mind. This means that the system is more demanding for flexibility and processing power, and traditional software-programmable embedded processors have become unsatisfactory. Fixed hardware processors and application-specific devices are making way for fully programmable devices and systems. For system designers, the dynamic configuration and optimization of system hardware can be as easy as software. Performance requirements continue to grow, and OEM automakers and end consumers demand more and more features and functions. There are more and more cameras and sensors on the car, and the drive network architecture and bandwidth have changed dramatically. Functional safety and security features are another key factor driving the car to a semi-automatic and ultimately fully automated evolution. Kevin Tanaka, Senior Manager, Automotive Marketing and Product Planning, Xilinx: As early as 2004, Xilinx started the XA (Xilinx Automotive) project and is now the world's leading supplier of automotive-grade programmable logic devices. The flexibility and scalability of the XA product line allows customers to develop customized platforms to meet higher levels of product differentiation and innovation. With the Zynq 7000 All Programmable SoC joining the XA product line, the industry's first hardware and software programmable devices address the technical and business challenges of the fastest growing ADAS market in the automotive applications market. Micron: Storage bandwidth is often a performance bottleneck for ADAS systems Modern ADAS systems have multiple sensors, such as high resolution/high frame rate cameras, radar, laser scanners, and night vision devices. These sensors (especially video cameras) need to use high data bandwidth to write data into volatile storage. A digital signal processor (DSP) device reads sensor data from storage and performs complex ADAS algorithms. The algorithm will access the storage multiple times while processing each video frame, and requires a high storage bandwidth. This process often becomes a performance bottleneck for the ADAS system. In addition to bandwidth, another major issue facing automakers is size. For storage configuration, proper consideration of density, power, size, performance, temperature, reliability, cost, and support is required. Active security systems currently use MCP while significantly reducing storage footprint. Storage MCP can stack non-volatile storage (NVM, enabling boot/application, execution of operating systems and other important code/data) and volatile storage (RAM, which can be used as a scratchpad) into a single package . In addition to reducing space footprint, reducing ball count, and improving performance and density, MCP can also offload embedded memory from microcontrollers (MCUs) using industry-standard JEDEC interfaces and storage types to reduce design time requirements Factors to consider. The next goal for ADAS designers is to create an integrated system network that interfaces with other vehicles and roadside traffic monitoring stations. Vehicle-to-vehicle (V2V) communication anonymously exchanges vehicle data about azimuth, speed and position, allowing the vehicle to detect other vehicles and 360-degree visibility into the orientation of other vehicles and potential threats or hazards. It then calculates the risk and warns the driver or takes pre-action to avoid or mitigate the crash. Toshiba: Focus on the research and development of the ADAS system For advanced driver assistance systems, the most important thing is to provide a solution for safe driving without burdening the driver. The ultimate goal of this active research is driverless. It is hoped that future advanced driver assistance systems will continue to add functionality and improve processing power in applications. Toshiba is focused on the research and development of the ADAS system by adding the Visconti line of products. The ADAS system requires SoCs to support simultaneous identification of multiple targets, including lane lines, vehicles, pedestrians, and other targets, and requires fast and low power. Toshiba Electronics (China) Co., Ltd. Senior Manager Huang Wenyuan: Toshiba's CoHOG recognition technology further enhances its recognition capabilities. Due to hardware processing, Visconti allows the use of graphical features for fast and high-precision identification. The processor also has an image processing accelerator that enhances the stability of recognition in light and small deformation states and enhances the characteristics of human recognition, which also improves the performance of image recognition.
