The National Highway Traffic Safety Administration (NHTSA) of the US Department of Transportation also issued two documents to solicit opinions on the vehicle-to-vehicle (V2V) technical standards. One of the documents is the Notice of Advance Notice (ANPRM) and the other is the research report entitled “V2V Technology Application Readyâ€. The two reports mean that after more than 10 years of research on vehicle-to-vehicle (V2V) communications, the US automotive safety regulator has finally taken a critical step forward.
So far, the cars on the roads are still independent transportation devices, and there is no communication between them. The emergence of V2V communication technology is to change this situation, let the vehicle become a mobile communication terminal, let all vehicles network, exchange information with each other. In this way, safety information such as position, speed and direction of travel can be issued to each other, thereby greatly reducing the occurrence of automobile collision accidents and alleviating traffic congestion. In conjunction with other high-end driver assistance systems, this technology alerts the driver in all dangerous situations to start the steering and braking system in an emergency.
The V2V communication technology is very beautiful, but it has not been widely used for various reasons. The two documents of NHTSA have seen the application of this technology. Suppliers at all levels have been gearing up and waiting. NXP Semiconductors, a global technology leader in the field of secure connected vehicles, today announced that its RoadLINK TM chipset, which enables V2V and vehicle-to-infrastructure (V2I) communications, has been mass-produced and supplied to Delphi Automotive. The chipset will eventually be used on GM's 2017 Cadillac CTS model.
According to Drue Freeman, senior vice president of sales and marketing for NXP's global automotive electronics business, RoadLINK TM enables wireless communication of vehicle-to-vehicle and vehicle-to-traffic infrastructure, enabling vehicles to exchange data on position, speed and direction for the driver to own. 360-degree sensing capability enhances road safety by reducing collisions, alerting for potential hazards, and avoiding traffic jams. The V2X chipset is beginning to be mass-produced, and it means that NXP is the world's first supplier of V2X chipsets for secure connected cars.
More importantly, the chipset communication method is based on the 802.11P wireless communication protocol, which is an open WIFI communication standard, so any vehicle using the same frequency band can communicate, and is not limited to vehicles using the RoadLINKTM chipset. This interoperability and open communication methods are critical to the popularity of V2V.
In addition, the reason why this RoadLINK TM chipset is favored by the OEM is that it contains important security features.
"The world of car networking is very good on the one hand. On the other hand, it has many weak points. We need to strengthen its security. For example, any radio frequency connecting the car and the outside world will become a weak point that hackers may use. Said Freeman. "Once the hacker breaks it, the consequences are very serious."
In some applications, security can also be achieved through software, but when it comes to life-and-death applications such as driving safety, software security is not enough. "In such an application, a hardware security policy is required. In the hardware security policy, it must also be ensured that the hacker cannot reverse the security by reverse engineering," Freeman pointed out.
NXP's IC products are widely used in the banking and government sectors, and their safety has been tested for a long time. In the automotive industry, NXP's security chips are used in automotive security systems, including in-vehicle networking, communications in the B2B, B2X, and entertainment systems and key management.
Such a secure tamper-resistant security chip is included in the RoadLINKTM chipset. It is certified to ensure that any piece of information received by the vehicle comes from a real, reliable and trusted source, ensuring the safety of in-vehicle information and driving.
Regarding the future development of V2V, Freeman said: “In 2016, vehicle-to-traffic facilities can be exchanged, especially in front of road hazard warnings. Vehicle-to-transportation facilities will be the earliest application. By 2025 or 2020 to 2025 In the year, all the functions of V2V will be realized, including blind spot detection and warnings to other vehicles during steering, which will be implemented one by one."
However, he also pointed out that the power of the government also plays an important role in such a process. For example, the rules on V2V communication technology that NHTSA will introduce will speed up the development of this process.
