It has only been a short period of more than 100 years since the invention of automobiles, but the development of automobile technology affects the development of social science and technology, and has a non-negligible impact on the development of human civilization. Therefore, the development of automobile technology should also be promoted with the purpose of benefiting mankind. The development of the world. From the most primitive transportation function of the car to the current smart car networking life, the development of car multimedia technology has given car users a convenient and rich car life experience. And back to the beginning of automobile multimedia technology, how many people know his history? Let’s take a look:

The development of automobile multimedia technology can be summarized as follows: car audio equipment, GPS positioning and navigation equipment, intelligent display system and intelligent transportation system.

Car audio equipment

Car audio equipment is the earliest electronic product used in automobiles. Although it is only an auxiliary device, it has no effect on the running performance of the car. However, as people’s requirements for enjoyment indicators are getting higher and higher, car manufacturers’ Increasingly attention is also paid to the application of. After more than 80 years of development, it has evolved from the original car radio into a comprehensive multimedia car electronic system integrating audiovisual entertainment, communication navigation, assisted driving and other functions. It has become an indispensable part and function of future cars. One of the basis for evaluating car comfort.

With the widespread application of multimedia storage media, NANDFlash-style virtual multi-disc CDRadio has begun to be promoted, and plug-and-play car audio such as USB and SD cards have appeared in the market, which is expected to replace CDRadio with mechanical movement structure. In order to improve the reception effect of car radios, the promotion of digital broadcasting (DAB, WordSpace, XMRadio, SiriusRadio, etc.) has made car radios an epoch-making revolution.

The development trend of automobile multimedia

In order to occupy the market share, domestic and foreign car audio manufacturers continue to introduce various products with advanced performance and unique functions to attract users, such as: unique anti-theft system, optical fiber transmission, holographic laser head, CD changer electronic shock, edge Rotating disc anti-scratch movement, ultra-low intermediate frequency digital tuner, high-quality satellite tuner, sliding open front operation panel, MASK new secret hiding mechanism, intelligent control dial, dynamic super bass, dynamic road noise control, three-dimensional audio and video system , Voice recognition system, driver's seat sound field simulation system, sound recording, etc.

GPS positioning and navigation integrated vehicle equipment

GPS is the abbreviation of English GlobalPositioningSystem (Global Positioning System), and its Chinese abbreviation is "ball position system". GPS positioning system equipment is also our common car navigation system. It is developed from the original car DVD equipment and integrates the global positioning system to facilitate car users to query and navigate to the destination. It is also a traditional stand-alone car navigation system. In car navigation, it is divided into two types: front loader and rear loader.
