Automotive circuit diagram is considered as the revolution in automotive technology development process, and the degree of automotive circuit diagram is counted as weighing the important symbol of Hyundai Motor level, is used to develop new model, improves the most important technical measures of automotive performance.Automaker thinks increases the quantity of vehicle electronics, promote that automotive circuit diagram is the important effective means capturing future automobile market.
According to statistics, from 1989 to 2000 years, the ratio that averagely on each car, electronic installation is shared in whole automobile making cost is increased to more than 23% by 16%.On some limousines, using the quantity of one chip microcomputer to reach 48, electronic product accounts for more than the 50% of integral vehicle cost, and the application of current electronic technology has been deep into all of system of automobile.
According to the impact division on 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 to be carried out with the use of, the auto electroincs of i.e. so-called " electric-mechanic control system " with mechanical system on car；They include 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 include vehicle information system (car running computer), navigation system, automobile audio and tv entertainment system, Vehicular communication system, equipment for surfing the net etc..
Automotive player has been requisite equipment on Hyundai Motor.
Existing automotive player does not all have and speed is associated.
Total well known, during car speed difference, the noise level in automobile is also different, and often when car speed is slow, the volume of player be can't hear when automobile is fast, and when automobile is fast the volume of player to car speed slow down time the most noisy, driver has to the volume regulating automotive player frequently, on the one hand, Consumer's Experience extreme difference, on the other hand, need driver ceaselessly to adjust volume, disperseed the notice of driver, easily caused traffic accident.
Patent " automobile player based on velocity measuring " (application number: 201510443345.9 applyings date: 2015-07-27) discloses a kind of automobile player based on velocity measuring, comprises velocity sensor, control module, signal input module, image processing module, acoustic processing module, display module and loudspeaker；Described control module is connected with signal access module, velocity sensor, image processing module, acoustic processing module, display module, loudspeaker respectively, and described image processing module is connected with display module, and described acoustic processing module is connected with loudspeaker；Described velocity sensor is for sensing the travel speed of vehicle, and passes it to described control module；Described signal access module is for accessing the signal of media to be play；Described image processing module is used for processing picture signal, and the picture signal after processing is transferred to described display module and shows；Described acoustic processing module is used for processing voice signal, and the voice signal after processing is transferred to described loudspeaker and plays out；Described control module controls display module and the duty of loudspeaker for the travel speed according to vehicle.
This patent is only at security consideration and speed and volume is linked together rigidly, does not solve the problem that driver needs not stop to adjust volume.
