In the past 10 years, the automotive industry has undergone two significant changes. First, the growth base is shifting from the European and American markets to the developing markets dominated by Asian countries. Data show that in 2007-2012, Asia and Europe will dominate 89% of global vehicle production; second, in the mature European and American countries, the performance of cars is more dependent on electronic technology. Studies have shown that from 1989 to 2010, the proportion of electronic equipment in manufacturing costs increased from 16% to more than 40%. At present, the IC cost of each new car is about $310, and it is estimated that it will grow to around $400 by 2015. Whether the market focus shifts to developing countries or the focus of technology is tilted toward electronic technology, it will inevitably affect the direction of automotive electronics development. Moreover, the technology itself will face stringent requirements from performance, safety and environmental regulations. The next 10 years, electronic technology in the automotive industry plays a significant role in how much, how it should assume the task of electronic automobiles? In this paper, expert analysis on a number of global professional body of the car manufacturers and spare parts manufacturers, looking ahead 20 years Automotive The development trend of the electronic direction.
Green, security and communication are the future of automotive electronics
Delphi's comprehensive investigation and research into global trends driving new technologies, products and markets around the world reveals that the future of the automotive electronics industry is green, environmentally friendly, secure and connected.
(1) Environmental protection. The most important development trend in the global automotive industry is the development of engines with high efficiency and low carbon emissions. There are many options, one is the advanced diesel engine and electronic control system. When driving on the road, its fuel economy is 30%~40% higher than that of gasoline engine. The second is electric power system or hybrid electric vehicle (HEV). . Hybrid automotive technology has many structures, but all involve a small battery pack, an electronic controller, and an electric motor that allows the car engine to automatically shut down when parked and re-accelerate the car before it automatically restarts. Hybrid vehicle systems can improve vehicle fuel economy by 30% to 40% and reduce carbon emissions by up to 60%.
The research and development of pure electric vehicles continues, and the scope has been extended to electric vehicles or plug-in hybrid vehicles. These cars use larger battery packs that can travel longer distances with purely electric drives. Finally, suppliers and automakers are developing systems such as cylinder pressure sensing and homogeneous charge compression ignition (HCCI) to make greater progress in terms of economy and gasoline engine emissions. All of these innovative powertrain technologies will add a lot of electronic content to cars around the world in the next 5-15 years.
(2) Security. The second major trend in the development of automotive electronics is safety. The market has a huge demand for technologies and products that ensure safer driving. Significant advances have been made in passive safety technology – technologies and products that provide protection for drivers and passengers in the event of a collision, such as crash sensors, airbags, seat belts, follow-up steering structures, and metal plate collision zones. Other products and technologies have saved many lives and reduced personnel injuries in car crashes. However, the latest development direction is active safety, measuring cars and surrounding objects by using radar, optical and ultrasonic sensors. Distance and speed when approaching an object. This data can be used to alert the driver to the driving speed of the car and to avoid possible collision events. This information can also be used to control the brake or steering system to automatically avoid collisions. The collision avoidance system can reduce the global accident rate as well as the costly cost of car accidents.
(3) Connected communication. The third major trend in the development of automotive electronics is the communication connectivity of automobiles. Today, consumers around the world can enjoy the benefits of digital electronics and wireless infrastructure at home and in the office, such as digitally compressed music and video on mobile phones, hard drives, digital TV playback, Wi-Fi, audio and TV satellite broadcasting (XM/Sirius, DirecTV) and GPS. Now, consumers are beginning to want the same technology and communication convenience in their cars and trucks to make the driving process more efficient, convenient and fun. Products and technologies such as GPS navigation, in-vehicle information services (automated telecoms from embedded mobile phones and other two-way wireless links), satellite radio and rear-seat television are the best examples of this trend.
Countries around the world are developing the aforementioned environmentally friendly, safe and connected automotive electronics . However, there are differences in the timing of product launches and the technical standards used. Japan leads the world in many automotive electronics innovations such as navigation and hybrid vehicles. Europe is closely following the navigation system, but it is in a leading position in mobile phone technology and mobile phone information services. North America is closely following Japan and Europe in developing the navigation market, but it is the first to adopt in-vehicle information services and develop satellite broadcasting and video systems. Moreover, although Japan first developed hybrid automotive products, the North American market is now the fastest growing market for hybrid vehicles.
Many technical standards around the world are constantly evolving. The most typical examples are mobile standards such as GSM and CDMA. GSM and its derivatives are widely used in Europe, while North America allows the use of GSM and CDMA as the basis for competition between mobile service providers. Asian countries have chosen GSM or CDMA as the mobile phone standard, and some regions have chosen two standards. At present, the standard for digital terrestrial television in Europe is DVB-T; and the standard for HDTV in the United States is ATSC which is not mobile friendly. Wi-Fi has become a global standard and an ideal choice for car connectivity within a local network, such as connecting a car in a garage to a home multimedia system or retail outlet, a convenience store, or a local network around a gas station. WiMax is a broader metropolitan area network that has begun to be used as an update standard in some countries. China's development is also exciting, and China's local version of WiMax and digital terrestrial video systems have been established and adopted. Initially, the standard millimeter-wave frequencies of anti-collision radars vary from place to place, but most countries today use the W-band 76-77 GHz frequency for active safety.
Over the years, Delphi has manufactured and sold many AM/FM analog radios with CD playback capabilities that have been the entertainment and information center for cars for decades. In recent years, the digital electronics and wireless infrastructure revolutions have begun to change the traditional model that Delphi has led. First, with the introduction of the in-vehicle information service system, the embedded mobile phone module enables two-way location-based data and hands-free voice communication. Initially, the in-vehicle information service unit was a separate box, and today, the in-vehicle information service unit has become part of the “radio†in the center of the dashboard. The navigation section was originally a stand-alone unit, and navigation is now only one of the features of digital infotainment radios. Similarly, the original XM/Sirius satellite radio was a remote receiver, but today it is also part of the radio.
In the future, the "radio" will develop into a sophisticated, highly integrated infotainment server, or "connected car" computing and communication platform. At the heart of the future radio is the extremely fast 32-bit microprocessor with powerful storage for its flash and hard drives. The human machine interface will include a large, high-brightness flat-panel touchscreen display, as well as a speech recognition and steering wheel control system. The "front end" of the radio will integrate multiple unidirectional and two-way wireless receiving subsystems, including AM/FM, mobile, GPS, satellite audio and video, Wi-Fi, WiMax, digital terrestrial TV and other emerging wireless connections around the world. The connectivity platform will also enable consumers to use a variety of portable or "nomadic" consumer electronics devices (smartphones, iPODs, etc.) in their cars and seamlessly connect to infotainment servers via Bluetooth, Wi-Fi or direct USB connections.
In addition, the GPS navigation system will become one of the functions of this radio. Navigation data can be downloaded via wireless link or stored on a flash card for use in a car. Real-time traffic and traveler information data will be obtained via wireless links and can be updated frequently for dynamic navigation. Finally, drivers and passengers will have a variety of entertainment options, from real-time audio and video playback to large-scale entertainment files such as non-real-time downloads of movies via Wi-Fi and WiMax.
We expect that the fastest growing areas of the automotive electronics industry in the next 5 to 10 years will focus on advanced safety electronics, infotainment systems and power electronics for hybrid vehicles and other advanced engine controls that improve fuel economy and reduce carbon emissions. system. According to data from Strategy Analytics, a global market research firm, sales of hybrid vehicle systems will increase at a rate of 20% per year, depending on fuel prices and government regulation in each region. They also expect safe electronic products to grow at a rate of 11.7% per year, while infotainment systems will grow at a rate of 11.4% per year. China, India and Southeast Asia are the fastest growing regions, followed by South America, Europe and North America.
