Consumers have chosen cars, and they have begun to shift from external hardware comparisons such as the appearance, engine performance, and speed, to the emphasis on interior equipment, texture, and other soft enjoyment. They have even stepped into value-added services and after-sales services. The multimedia audio host, digital television, and satellite navigation have all started to integrate into the car. The in-vehicle communication and entertainment system has gradually received attention. Therefore, the difference brought about by the software has brought about the vigorous development of automotive electronics. Of course, it is the automobile, Computers and semiconductors are coming together.
Automotive Aftermarket Status
The new car is hard to satisfy, so many owners are looking for modifications and retrofits; the older models are less computerized and less difficult in terms of electrical systems. However, the new car models are becoming more and more completely computerized. The degree has also increased the technical threshold. Take the car audio and video system as an example. Many domestic car models have almost no difficulty in installation. However, many premium car models or imported models have increased their compatibility due to the use of a nearly closed system and low compatibility between different brands. Subsequent difficulties in upgrading space.
For example Mercedes Benz, BMW, Lexus cars, using HarmanKardon, Mark Levinson brand products, no problem to change the horn, but integrated in the center console multi-function audio host, combined with a variety of information and control functions, if you want to add extra For digital products such as digital television and satellite navigation, if the restrictions on the blockade of the original audio system are not broken, it will be difficult for consumers to add extra audio/video devices. In addition to the audio and video system, other modifications have also been affected. The European-style cars have adopted seemingly closed traffic computer systems. The degree of computer integration is high, and there are also many difficulties and technical barriers for Japanese-related modifications.
For example, Civic8's audio console is integrated in the center console, built-in MP3 and WMA format reading capabilities, coupled with integrated design, the owner is slightly more difficult to modify. And FordFocus also integrated the audio host in the center console, which is almost a common trend of the new car models, and the multimedia format of the reading function is becoming more and more popular, it is no wonder that the conversion industry sigh business hard to do.
New car integrated audio and video system
In view of consumer supreme considerations, modern car models not only have become more streamlined in appearance, but have made great progress in interior decoration, among which the integration of various electronic products is the most complete. Now the original audio console, multi-slot CD player, MP3/WMA format function, AUX external input and other functions; plus the trend of promoting leisure and family, the surrounding products are also on the train. Even many car manufacturers have been listed as standard equipment, such as digital television, satellite navigation, etc., and are integrated into the large screen on the center console under the premise of a beautiful cabin.
Not only that, the operation also strives to be convenient and convenient. Therefore, at the steering wheel's fingertips, the quick keys for designing and placing the operation can not only control the main functions of the audio host, but also combine the communication equipment to get one finger, even in the mobile phone. The phone book can also be uploaded to the host computer. After the car is accessed, the host computer on the car will do the communication. In addition to the convenience, the driver of the conversion industry may suffer. The control function of the steering wheel needs to be connected with the adapter developed by the manufacturer after the host is replaced. The general audio store cannot connect the reservation control function in the traditional way. The imported cars mentioned in the preceding paragraph must be added after a decoder called the black box, in order to add the products that consumers want to install, and each system is different, which increases the difficulty and the threshold.
Many old car models use their own independent designs. The degree of integration and aesthetics are certainly not new. However, many traditional car owners still have room to survive.
Car platform operating system advantages and disadvantages
Vehicle operating platforms are not as good as home computers. They require complicated and many different purpose instructions, which are much simpler, but also because of the relatively hot operating environment, humidity, vibration, power supply and other factors, they are simple and durable, and have high reliability. On the contrary, it is the most important consideration.
The current hot CarPC (operating OS for Windows Automotive 5.0 or Windows CE), mainly for the control of audio-visual systems, is equivalent to a small notebook computer on the move, of course, the operation is also like home computer-like mode, It should be quite familiar to consumers.
However, it also has the same disadvantages as the home computer, and it has a high degree of openness and adaptability. It has the characteristics of low cost, low memory requirements, etc. The Linux product of the embedded system provides fast and The flexible development environment has become the best choice for a new generation of automotive operating platforms. To put it more plainly, the work of the on-board operating platform is not particularly complicated. Some instructions are even simple detection and feedback actions. From a certain point of view, it is very much like executing a large-scale program. Close to the average consumer's Windows system, has the advantage of easy to use, easy to operate, but in the face of automotive environmental requirements, the reliability of the Linux system and high reliability can not be ignored; therefore, the structure of the vehicle operating platform, its constitution The superiority or inferiority is extremely important.
Longer carriages increase inconvenience
Different OEMs use different operating platforms and audio/video system brands, which means that they are independently developed. However, the design and development of automotive electronic applications is time-consuming and costly, and it is also necessary to overcome the relatively closed environment of the traditional automotive industry, for any one manufacturer. All are extremely high challenges. Therefore, if all plants work together to develop a uniform standard operating platform, not only reduce research and development costs, but also under this premise, research and development of the plant's unique exclusive equipment, and ultimately beneficiaries or consumers. Moreover, the rear-end modified product development plants are also best able to form alliances with each other. After all, the combined alliance is more powerful than the spoilers.
In the United States, for example, a VIIC Vehicle Integration Infrastructure Consortium (VIIC) consisting of major automotive companies, consisting of BMW Automotive North America, DaimlerChrysler, Ford, GM, Honda North America R&D, Nissan Motors North America, Toyota North America Engineering and Manufacturing, Flowserve America, and other heavyweight automotive companies. This alliance cooperates with the US Department of Transportation and several state governments and hopes to build an industry-standard communication infrastructure through the OBE plan to support vehicle-to-road systems and automobile-to-vehicle communications to improve traffic safety and vehicle efficiency, even This architecture provides consumer or business services. Through this alliance, depots can develop value-added products or services for the cars they produce at an affordable cost and on a standard or platform that they can follow.
VIIC chose WindRiver's Linux system as the proof-of-concept development platform for On-Board Equipment (OBE). WindRiver is a global leader in embedded Linux systems. VIIC selected Linux as its operating system and selected WindRiver Linux as a platform for commercial distribution. It wanted to take advantage of the stability and scalability of Linux and the advantages of using a commercial Linux platform, such as a high degree of integration and a reduction in overall Development costs, accelerated time to market, etc. These are the challenges that manufacturers who are interested in the development of automotive electronics need to overcome.
The position of the software in the vehicle equipment has become more and more important. The open source software further provides great convenience for the development of the vehicle equipment, but it also brings a lot of trouble to the interaction between various technologies and equipment. To this end, leading car manufacturers and suppliers have jointly established GENIVI Llliance. The non-profit organization, together with industry-leading automotive, consumer electronics, communications and application software development companies, injects capital into the IVI market and promotes innovation in the industry. It is committed to promoting the development and popularization of the IVI open source reference platform. This will not only shorten the time to market, but also reduce the total cost of ownership.
Founding members of GENIVI Alliance are BMW Group, Delphi, General Motors Corp., Intel, Magneti Marelli, PSA Peugeot Citroen, Visteon Corp, and Wind River. Working together to create a G ENIVI sharing platform, a common software architecture that can be extended across the entire product line and product generation. The prototype runs through the Intel Atom processor and WindRiver Linux. The reference implementation will be launched in the form of open source code to promote developer innovation. It is worth noting that Intel and WindRiver originally participated in the establishment of GENIFILIlliance as two independent companies. Now that WindRiver has been acquired by Intel and become a wholly-owned subsidiary of the company, this new pattern will be more beneficial to the development of GENIVI LIIiance.
Smart guidance and active tips
In fact, the practical application of the above-mentioned functions has similar success stories in the car industry. GM developed the so-called OnStar system for its cars, providing additional services such as security, theft prevention, diagnostics, and emergency rescue; and these additional services will further develop simple, intuitive development and set up three directly in the car. Buttons, drivers can enjoy these services very easily.
Remember the new Volvo car ads? A professional woman stooped to collect the information on the floor. She did not notice that the distance to the vehicle was approaching. At this time, the ACC active distance control tracking system took the initiative to detect that the safety distance was not maintained, which in turn conveyed instructions to the control module for braking. This is the active safety protection of the car against the car. Once the above-mentioned OBE interface platform is unified, new technologies like Volvo cars can be used not only in vehicle-to-vehicle and vehicle-to-ground, but also in two-way initiative; combined with functions such as communication and entertainment, such as pre-prompting traffic conditions and traffic signs. Pre-display, combined with satellite navigation, local related information, etc., believe that it can provide the most complete and user-friendly driving information.
Technology always comes from human nature
Just think, when you want to go to a movie or travel with your car, you need to set your destination at home and use the satellite navigation voice to guide you; take the initiative to send signal messages along the road (or estimate the remaining seconds of the signal). ), can be judged after knowing in advance. Even before you reach your destination, guide to a nearby parking lot and provide local navigation information. Is this trip good enough? Don't forget to set a fixed speed while driving. The on-board computer can detect dynamic active protection at any time. Passengers in the car can enjoy the audio and video multi-media feast all the way to a happy arrival. Afterwards, driving can really be said to be extremely happy!
