Description
Technical field
The present invention relates to vehicle electric field, particularly relate to a kind of automobile player based on velocity measuring.
Background technology
Automotive electronics is the general name of car body electronic control device for vehicle and vehicular automotive electronic control device.Car body electronic control device for vehicle, comprises engine control system, chassis control system and electrical control unit system (body electronics ECU).The most notable feature of automotive electronics advances to control systemization, with the electric-control system of sensor, microprocessor MPU, actuator, tens of even up to a hundred electronic devices and components and parts thereof composition, just obtaining market extremely widely.Car body electronic control device for vehicle is just like human body that is bald-faced, that do not dress any clothing jewelry; Vehicular automotive electronic comprises vehicle information system, auto-navigation system and automotive entertainment system.Vehicular automotive electronic control device is just like clothing, the jewelry of the person.
Automotive circuit diagram is considered to the revolution in automotive technology development process, and the degree of automotive circuit diagram is counted as the important symbol weighing Hyundai Motor level, is used to develop new model, improves the most important technical measures of automotive performance.Automaker thinks that the quantity of increase vehicle electronics, promotion automotive circuit diagram are the important effective means capturing future automobile market.
According to statistics, from 1989 to 2000, the ratio that on average on each car, electronic installation is shared in whole automobile making cost increases to more than 23% by 16%.On some limousines, use the quantity of one chip microcomputer to reach 48, electronic product accounts for more than 50% of integral vehicle cost, and the application of current electronic technology has almost been deep into all systems of automobile.
Divide according on the impact of running car performance effect, automobile electronics can be summarized as two classes: a class is electronic control device for vehicle, electronic control device for vehicle will carry out with the use of, i.e. auto electroincs of so-called " electric-mechanic control system " with mechanical system on car; They comprise engine, chassis, electrical control unit.Such as electronic fuel injection system, braking anti-lock control, anti-sliding control, polling power controlling, electronic controlled suspension, electronic automatic transmission, electrical power steering etc., another kind of is vehicular automotive electronic device, vehicular automotive electronic device is the electronic installation that can independently use under automotive environment, and it there is no direct relation with the performance of automobile itself.They comprise vehicle information system (car running computer), navigational system, automobile audio and tv entertainment system, Vehicular communication system, equipment for surfing the net etc.
The electronic-controlled installation of present automobile has had very complete consideration to various situation, but, still there are some places not consider: existing automobile Play System generally only considered tonequality or the video quality problems of broadcasting, do not consider that automobile is taken sb's mind off sth unsafe problem in motion.
Patent " Vehicular video-audio player " discloses one and utilizes mobile hard disk (USB flash disk) as the Vehicular video-audio player of audio-visual carrier, it comprises USB flash disk, selection key, control panel, receiver circuit, volume control circuit, power amplifier, LCDs and loudspeaker, feature also comprises USB (universal serial bus) (USB) interface circuit, center-control and decoding circuit, storage inside circuit, center-control and decoding circuit are searched for by USB interface and are read the video compressed in USB flash disk, audio-frequency information, video, audio-frequency information is after center-control and decoding circuit decoding, be reduced into vision signal in liquid crystal display screen display, sound signal through power amplification is played back by loudspeaker.
This patent is owing to adopting USB flash disk as image and sound program carrier, USB flash disk, usb circuit, center-control and decoding circuit and existing automobile audio circuit are organically combined, therefore have that image and sound program memory space is large, source of sound enriches, not affected by vibration, play stable advantage, but it does not consider the safety problem of car steering, sometimes, resource is abundanter, attracts driver attention more, more dangerous on the contrary.
