New possibilities for car networking technology

At the 2014 SAE (Society of Automotive Engineers) World Congress, which began on April 8, a professional seminar titled "New possibilities for car networking technology" explored many technical and social issues. The highlights of the Cheung Yee Finishing Conference are as follows:

Connected cars change the pattern of future life

John Robb, senior manager of electronic systems development at Hyundai Group's American Technology Center, said:

With satellite and Internet radio, AM/FM frequency modulation, cellular communications, and car networking technology, cars have formed a new ecosystem of data that can be freely circulated from a relatively closed state, and the speed of onboard technology in the future will be very fast. For consumers, this is not just about networking, they are even more looking forward to the future of the car can become a continuation of their living space.

Internet cross-border to insert the automobile circle

As social media and consumer electronics technologies become more and more important, technology giants like Apple and Google can't help but get into the auto industry. For them, networking not only means that the contents of the car entertainment system will be more abundant and the functions will be more personalized. At the same time, derivative products such as online shopping cars are also the focus of Internet companies.

Meredith Guerriero, Google’s global business director, said:

The world's largest car dealership can attract 2 million customers each year to shop inquiries, but the number of people visiting its website can reach 10 million every year. From the start of baby boom, a new generation of car users not only has extremely strong purchasing power, but also has a long-term impact. Although there are many opportunities for car companies, this has brought severe challenges to OEMs in many aspects.

Caring service can catch the user's heart

Many experts said that major OEMs that develop and produce different system platforms should unite to cope with increasing external pressure. However, the abuse of auto user data has become one of the challenges faced by the current networking market.

OnStar CTO Timothy Nixon:

If there are any internal faults in the car, then the data information will be uploaded to the network through the communication bus, and then the relevant system will send the next instruction to tell the user how to operate. So it is not difficult to see that the interaction process like this is very complicated. For example, when the driver sees that the engine fault light is on, he will certainly be very crazy in his heart. However, we have a lot of APP applications that can help users interpret the meaning of this type of information, so as to assist the driver in the detection of the vehicle condition and ensure the safety of driving.

V2V, security precautions have to be awake

The human-vehicle interconnection is only part of the future roadmap for networking technology, and V2V (vehicle communication technology) is expected to gain social recognition in the coming years. At the same time, it is not difficult to find that V2V is an essential element of autonomous driving technology.

When a car communicates with a car, a car, or a utility system, the data transmitted by the authorized transmitter is not intercepted by hackers or other "bad intentions". This is critical. With the maturing of V2V and V2X technologies, necessary preventive measures become more and more important when the interconnection technology enters the field of security.

"Security is an important aspect of V2V communication technology that cannot be ignored," said Bruce Belzowski, Automotive Analyst, director of the University of Michigan Transportation Research Institute (UMTRI). "Although according to current testing, the security of V2V technology is very reliable." However, we are still working hard and we hope that the future V2V will become more secure."

As the degree of interconnected technology becomes more and more complex, the interaction between systems is also becoming more frequent, so conventional testing is also quietly undergoing transformation. At the same time, digital modeling and process simulation have also been widely used in practice.

Stephan Tarnutzer, Chief Operating Officer, DGE Inc:

Uninterrupted testing is necessary. In the product design cycle, we must test while designing, and we can't wait until all the design is completed before executing the diagnostic program. In other words, testing and verification need to be carried out in the early stage of production, and it should not be reversed. In addition, the hardware in the computer loop plays a crucial role in the testing of the complete equipment.

summary:

With more and more functions and features of automobile integration, how to ensure the convenience of the user's operation and the safety of driving at the same time can be fully guaranteed. This is the key to the success of the car networking technology in the future.

The experts participating in the seminar believe that safety is always the key to automotive networking technology. Just as any new features added to the product must first consider the cost, before connecting the car to the Internet, WLC technology will affect vehicle safety. It needs more careful consideration than any other issue.
