-board computer is a highly integrated automotive multimedia entertainment center, BMW, Audi and other top models at present only in foreign countries only with a similar smart car system, its main features include all-around car multimedia entertainment, the most clear detailed GPS satellite navigation, car information and professional fault diagnosis, office and industrial applications of mobility. It motherboard, power supply, as the main display mounted on a vehicle in the form of distinction, a dedicated application software platform, a car multimedia message. Hyundai Motor on many devices each major system of the engine, chassis, transmission, electrical system, such as safety and comfort, the use of computer-controlled increasingly common.
1-board computer functions
binding navigation onboard computer, entertainment, and other needs of daily transaction processing, the appearance of small, high integration. As a new product used in high-end vehicles, vehicle achieve top-five PC functionality, and powerful scalability: navigation, networking capabilities, information indicates, entertainment, security functions.
cars as a pure means of transport is the development of a single function to multi-functional direction. The IT loadTo the car, it has become an important value-added solutions in Europe, America, Japan and other countries to achieve differentiation automotive products, and enhance market competitiveness. From a single radio to tape, CD, VCD, and then to develop common now appear on the market DVD, navigation, Bluetooth and other multi-functional integrated products, infotainment devices along the Chiang Kai-shek multifunctional, networked, intelligent trace the evolution, and more and more highly integrated. .
2-board computer having
1, the reference voltage regulator: providing a lower voltage and sensors to the computer.
2, an amplifier: the input voltage and current to improve the signal to the computer for use.
3, or converter, said controller: is an interface, perform switching signal supplied to the computer.
4, the housing: the housing is used to protect the metal of each electronic component.
5, the microprocessor: IC chip-based, for the computer to do calculations or decisions.
6, memory: based IC chip microcomputer for storing data.
7, clock, also known as Timing: IC means a certain pulse frequency, to tune action in the computer.
8, the output of the driver: a power transistor to increase the current, the actuator action.
9, the printed circuit board: holding and positioning the connection.
10, outlet: sensors and actuators and other connections.
3. The on-board computer to buy elements
1. The ability to navigate
job is GPS navigation, so we first see is the ability to navigate , navigation capability mainly to see two areas: hardware and software, hardware refers to the processing power of the processor, GPS chip is currently used by almost all SiRF hand, is divided into several files, and according to the same principles of computer clock speed difference, bring a lot of benefits clocked fast, first of all fluency and speed are promoted a lot, especially in the star search speed is greatly improved, this is due to the increase in the number of channels and improve the internal operation mode, the signal in good state , the basic orientation can in 20 seconds or less, the performance in weak signal is also very good, is not currently available using a multi-level chip PRIMA, ACCOQ7 be an early adopter of this chip on-board GPS, in addition the chip also supports 64 channels the GPS processing power.
storage systems, memory and use large 128MBDDR 8GB body storage system. Software refers to the map, the current mainstream map has Cn, Kay Rucker, etc., they have their own strengths, and that is true-ACCOQ7 using genuine map, and has recently upgraded to version 2.0, and compared to the previous version, version 2.0 Cn map the picture is more beautiful, the latest version of the 2.0-point information (POI) data has exceeded 13 million, far ahead of other competitors, is currently the most complete electronic information point map.
Cn version 2.0 not only is very rich in information, maps, route planning function is quite good, in planning the country’s northernmost to the southernmost route, much faster than other similar software, The reasonableness of the planned route, and it is unparalleled. In addition, Cn version 2.0 interface, operation, function and other aspects of the design also incorporates many user-friendly design.
2. The audio and video playback capability
GPS is moving in the diversified multi-functional development, like many GPS support CMMB video or audio playback, the current GPS to achieve this resolution in-car GPS rare, whether watching movies or photos are a treat.
3. The added value
In addition to film music these features, GPS also adds some interesting can expect to find features such as online stock, CE operating system, simulation games, etc., ACCOQ7 WINCE6.0 system is built-in Microsoft, which makes the product’s scalability is greatly increased, after entering the system, we can use it the same as using a computer, OFFICE, PHOTOSHOP and other commonly used software with all GPS can be achieved, there are many resources on the network, and it’s free, we can instantly put GPS into a gaming machine.
4. The product differentiation
different manufacturers are using several chips, will inevitably be repeated in function, but there are also tight encirclement, find more product selling point, many people purpose of the Internet chat as QQ or MSN, ACCOQ7 can actually achieve these functions, Q7 itself using WindowsEmbeddedCE6.0 system that scalability is very strong, of course, also supports MSN online, Q7 itself is built MSN.
4. Trends onboard computer
With the development of computers, many people choose to install the computer in the car as a vehicle-mounted machine to use, so that is not only powerful, but also more familiar with the operating system, you can continue to change the program according to their needs and style. On-board computer is a fast growing emerging markets, particularly in the field of logistics management-board, on-board computer will undoubtedly become a trend, because the commercial and public vehicles (trucks, trailers, police cars, fire engines, ambulances, tub, tankers, etc.) require efficient fleet management, so that the team dispatched to achieve better energy efficiency and improved.
At the same time, on-board computer also contains a considerable market risk, mainly based on different roles in the value chain positioning vary. But different positioning are concerned about some of the same problems.
It is worth noting that the majority of currently installed car market after computer makers are from the general IT companies in transition or industrial computer manufacturers, most do not have the high-quality automobile industry background.
Lin Weizuo stressed the need to design and manufacture a real need for more consideration to be highly unstable in the computer environment used car vehicle battery power, vibration, shock problem, wide operating temperature problem, broad Storage temperature problems, as well as highly integrated wireless communications module technology and so on, to overcome more than a single problem is not difficult, but it is not easy to solve all the problems. Auto industry will take a long period of supply and warranty, these are the challenges.
