Safety and interconnection are the key to realizing V2X and automatic driving

How will automotive electronics develop in the next 10 to 20 years? Maybe we will enter the era of autonomous driving, our cars will be smarter, drivers can enjoy food on the way, cars can communicate with transportation facilities to avoid congestion. “The automotive world is experiencing changes. The industry generally expects that there will be 50 billion devices worldwide connected by 2020. I would add that 10% of the 50 billion devices are more or less related to automobiles. That is to say, there will be 5 billion automotive-related devices connected by 2020.” Drue Freeman, vice president of global sales and marketing for NXP’s Automotive Electronics Division, said, “Which ensures secure information and secures interconnections. The driving safety of driving is also crucial. The back of autonomous driving is inseparable from the support of first-class connection technology and safety technology."

In the context of the Internet of Things and the Internet of Vehicles, NXP’s brand focus has also quietly changed. NW Semiconductor's global sales and marketing executive vice president Steve Owen said: "A year ago, NXP's brand focus has changed, from a manufacturer who attaches great importance to consumer electronics to become a company that attaches great importance to security technology. The car environment is becoming more and more clouded, and the car-to-vehicle and car-to-infrastructure connections make security issues increasingly prominent. Introducing non-contact RF technology into the car environment, building the car network (V2V, V2I) and ensuring safety is NXP One of the key directions currently considered in the field of automotive electronics."

V2X: Driving to a more advanced ADAS

For the realization of autonomous driving, Drue Freeman said: "The reason why the world of autonomous driving makes the road safer is because the quality of the decision made by the car itself through the Internet of Vehicles and other technologies is much higher than the quality of the driver's own decision. These decisions can come from the analysis of road conditions by transportation infrastructure or vehicle sensing devices. Currently, vehicle networking solutions are recognized by traffic management experts as the best solution to the challenges of increasingly serious road congestion and traffic accidents. V2X Including automotive-vehicle (V2V) and automotive-infrastructure (V2I) technologies, V2X enables seamless connection between vehicles (including drivers) and urban intelligent transportation systems, while relying on security technology to ensure information and transmission security, anti-hacking Attack or manipulation."

Recently, NXP announced that it will supply Delphi Automotive with a RoadLINK chipset that enables vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. This means that NXP has become a supplier of V2X chipsets for secure connected cars, and it also indicates that V2X chipsets are beginning to be mass-produced. The NXP RoadLINK chipset enables wireless communication between the vehicle and the vehicle to the transportation infrastructure, allowing the vehicle to exchange data such as position, speed and direction, giving the driver 360-degree sensing capabilities. Drue Freeman said, "This collaboration combines Delphi's platform, NXP chip technology and Cohda Wireless's application software to allow warning messages from surrounding vehicles and infrastructure to be delivered to the vehicle, alerting the driver to potential traffic hazards such as sight. Traffic lights and signs in the blind spot can be the best complement to the Advanced Driver Assistance System (ADAS), where road warnings can cover blind spots at intersections, road hazards, road construction, emergency vehicles, static or slow moving vehicles. Avoid reminders, traffic jams and accident warnings, and traffic signals or signs."

It is reported that the V2X solution is based on the wireless communication standard IEEE 802.11p (also known as WAVE, Wireless Access in the Vehicular Environment) designed for intelligent traffic needs. Unlike the home Wi-Fi standard, IEEE 802.11p ensures real-time transmission and information security in high-speed sports environments. According to Drue Freeman, "The RoadLINK chipset provided by NXP is based on a one-stop package solution. The chipset includes baseband chips, RF front ends, 802.11P protocol stations, middleware, etc., as well as independent hardware security modules. It can prevent illegal attacks or data theft. At the same time, in the test scenarios with very complicated road conditions and high speed, the test performance of the RoadLINK chipset is better than other manufacturers. This is the main reason why NXP beat the competitors. "For the application prospects of this technology, Drue Freeman added, "The V2X solution based on the RoadLINK chipset will be the first to be commercially available on GM models. I believe there will be more and more car manufacturers in the near future." Chinese manufacturers) announced the launch of a similar V2V vehicle project."

NFC: Application in the car environment

As a co-inventor of NFC technology, NXP leads NFC and security technologies in applications such as banking and mobile communications, and also hopes to bring this technology to the automotive industry, making NFC a key technology for seamless connectivity. .

According to Drue Freeman, “Looking ahead, NXP hopes to make automotive interconnect technology even better on an existing basis. In particular, NFC near-field communication technology enables consumer electronics, including smartphones, to seamlessly interface with in-vehicle networks. Since the related product technology has not been officially listed in the European and American markets, this will be a forward-looking introduction. According to reports, in the field of automotive NFC interconnection, NXP has launched a full range of NFC products, including automotive-grade NCI-based specifications. The NFC controller mainly supports NFC read/write functions and point-to-point functions. “NFC technology can realize the following applications in the car, such as simple pairing of Bluetooth or WiFi on the car, identification of the driver, activation of the car engine with a NFC-enabled smartphone, and help the driver to automatically adjust the comfort of the car. Such as the realization of memory air conditioning settings, seat settings, rearview mirror related settings, etc.," Drue Freeman said, "typical applications, such as in the car rental industry, car rental customers do not need to take the keys, can pass The authorized mobile phone opens/locks the door."

When these forward-looking technologies are used in the Chinese market, Chen Weijin, general manager of NXP Semiconductors Greater China Automotive Electronics, said: “Foreign car companies also have relevant R&D departments in China, and they are also thinking about in-car entertainment or other systems. Can you add NFC interface, let more information be converted through NFC interface. These Chinese car manufacturers also have great interest, such as NFC can quickly realize Bluetooth pairing, and automatically match the height of the body seat, the mirror and the temperature at the same time. Adjustments, these are applications that Chinese customers are very interested in. Some of our projects are already underway and I believe they can be seen in the near future."

Of course, Drue Freeman concludes: "In the future connected car world, security is becoming more and more important. Whether it is car networking or NFC, there may be security issues in any place where RF exists, so security vendors will play an increasingly important role. character of."
