Electronic applications in automotive systems have become a major part of new automotive platforms. "Safety, entertainment, energy saving" has become the three main directions of automotive electronics development. For the above three characteristics, cars must be combined into a scalable connection backbone architecture through wired and wireless devices, and the above functions are implemented in a centralized system. And "Internet of Vehicles" applications. On the whole, the average number of IC devices in every car is increasing. According to data provided by Strategy AnalyTIcs, in 2011, the total size of the automotive chip market was about 23 billion US dollars. In 2011, approximately 75 million vehicles were produced globally, of which 20 million were produced in Europe. At present, each car uses about 300 US dollars worth of chips.
Energy saving, safety and entertainment are still the three major directions of the automotive electronics market
In recent years, driven by market growth and changes in consumer buying habits, automakers have increasingly tended to use more complex electronic components to add new comfort features, while achieving higher safety and energy-saving emission reductions. demand.
In order to meet the needs of automobile manufacturers, chip manufacturers are also constantly developing new products and solutions. Infineon is one of the world's largest chip manufacturers in the automotive electronics field, with a 10% market share in this market. In addition, Infineon is the largest chip maker in Europe (with a 15% market share). In the field of single-chip microcomputers used in engine management and transmission control units, Infineon has more than 30% of the global market share. Recently Infineon just delivered its 100 millionth TriCore microcontroller. This makes TriCore MCU one of the most successful MCUs in the automotive electronics field and is used by more than fifty automotive brands. From a statistical point of view, this means that almost one in every two vehicles uses TriCore microcontrollers. This MCU is responsible for reducing fuel consumption and exhaust emissions as much as possible.
In terms of in-vehicle infotainment applications, vehicle and traditional vehicle machine companies are facing the challenges of handheld mobile terminals such as smartphones and tablets. The car is integrating more and more complex functions, with more human-machine interaction and more intuitive driving assistance. Experience, more media audio-visual entertainment projects, etc. For emerging countries such as China, some of the configuration of high-end cars in the past is showing a trend of shifting to low-end cars, such as higher-quality audio, graphic display dashboard, rear seat entertainment video, and more intuitive 3D navigation technology , Fully automatic air conditioning, parking assist system, etc. Of course, for many small cars in emerging markets, including China and India, low-cost car audio still has a lot of market space.
In terms of safety, products related to vehicle safety systems have grown rapidly in recent years. Among them, high-growth products include lane departure warnings, steering headlight lighting systems, integrated generators and controls, workshop distance warning devices, and tire pressure monitoring systems. With electric parking brake. Li Dan, a senior product engineer at Fujitsu Semiconductor, believes that compared with developed countries, China's automotive electronics market has a higher growth rate and potential, but China's automotive electronics market is still at a relatively preliminary stage, and Chinese local system manufacturers are better at The field is mainly focused on applications such as car audio, navigation, centralized body controllers, traditional instruments, etc., but rarely involves core technologies such as powertrains and safety systems.
"Intra-vehicle network" and "Internet of vehicles" become a new trend in the development of automotive electronics
In order to achieve the above three major characteristics of safety, entertainment, and energy saving, cars must be wired and wireless devices combined into a scalable connection backbone architecture, in a centralized system to achieve high-bandwidth intelligent applications and infotainment and advanced driving safety functions . One of the core technologies is Network.
TImothy Lau, Senior Product Line Manager, Automotive Network Products, Broadcom Corporation Infrastructure and Networks
By combining cost-sensitive Ethernet technology with high-resolution images collected from economical CMOS image sensors, Broadcom is enabling automotive OEMs to extend advanced parking assistance systems from luxury vehicles to non-luxury vehicles. Standardized IP technology has the ability to promote audio and video data display, infotainment, seat control management, passive restraint and more applications throughout the vehicle.
TImothy Lau, Senior Product Line Manager, Automotive Networking Products, Broadcom ’s Infrastructure and Networking Division, said Broadcom is working with many automakers to easily and cost-effectively integrate award-winning BroadR-Reach products into cars to Drive the latest and most advanced infotainment, navigation and Security systems. 2013 BMW X5 will be the first car to adopt Broadcom BroadR-Reach Ethernet technology. The car is equipped with the world ’s first 360-degree panoramic parking assist system, which is jointly developed by Broadcom, Freescale and OmniVision. developing.
In addition to in-vehicle interconnection, IoV applications have also become a new development trend in the field of automotive electronics, and may further subvert the traditional automotive industry. NXP brings telematics and car-to-x communication technology, as well as wireless technologies for car access control, near field wireless communication (NFC) and multi-standard digital broadcast reception, to the automotive industry. Extend the in-vehicle network system to the traffic infrastructure through a secure wireless connection. Road signs and vehicles can talk to each other to regulate traffic flow or warn drivers of danger ahead.
Taking the NFC technology as an example, one such application is an NFC-enabled connected car key. "As a smart device used in conjunction with a smartphone, the connected key allows you to easily find your car in a large parking lot or a strange city, and can automatically personalize your car settings and your favorite entertainment content. At the same time The interconnection key also allows automotive companies to simplify maintenance tasks and obtain vehicle diagnostic information even before opening the engine hood.
