Research On Application Of Infotainment System For Vehicle Base On MOST150

With the development of society, the vehicle has become a necessity. Meanwhile, thevehicle electronic technology has also been fully applied. Application of electronictechnology can make the vehicle easier to drive, and you can make vehicle driving safer,and you can work on the road, although in the vehicle infotainment system is only anauxiliary device, with the increase in vehicle infotainment system of additional features; itis now also one important indicator of automotive comfort. Meanwhile, importanthighlights various automobile manufacturers to pursue new models. It allows the driver toenjoy high-quality audio-visual feast in driving the process, and can provide a comfortableservice function for the driver. It makes our journey driving easier and more enjoyable.With the increasing demand for vehicle infotainment, and the traditional automobilenetwork which has low bandwidth, has been unable to meet the requirements of datatransmission media. MOST150network as dedicated infotainment media network, has thefeatures of high bandwidth and low interference, and so on, and has become the focus ofmajor vehicle manufactures attention. This paper basing on the MOST150standard, designand realize the main controller of MOST150network, and use it for in vehicle infotainmentsystem.This paper analyzes the principle of MOST150network transmission, and fromMOST150network structure and network protocol two aspects in detail. Based onfunctions description for2016infotainment system, structures infotainment systemarchitecture, network topology and control processes, which is based on MOST150, andcomplete infotainment system as a whole system framework design, and designprototype of MOST150network, basing on network interface controller OS81110, andconnect the prototype of main controller and other nodes with the fiber, and form aMOST150network. This paper gives the connection circuit of network interface controllerOS81110, CPU Freescale-I.MX6Q, a photoelectric converter and other components; andexpounds the main controller prototype software structure, message processing, and therelated program flow chart particularly; finally, described and summarized the MOST150network infotainment system test.In this paper, design the MOST150network controller prototype successfully, so that all nodes in the network work coordination, and validate the MOST150network high-speed,real-time, reliable, small interference characteristics. For the application of MOST150network in automotive electronics, intelligent Home Furnishing field, it provides the baseof theory and practice.Infotainment system is moving in depth. Major automobile manufacturers and partsmanufacturers are also actively explore and bring more driving fun and enjoyment fordrivers.
