Design and Implementation of an Around View Image Storing System Based on Car PC

The automotive electronic systems for effective driving include a navigation reflecting real-time traffic information, a blind spot camera for accident prevention, a black box for recording driving image prior and after accidents, an around view monitoring system enabling all the sides to be seen, etc. The existing around view monitoring system among them was developed based on the embedded system in order to provide real-time information around a car in blind spots and narrow spaces. In this paper, we have implemented an around view monitoring system which enables image storing by combining the strong points of the around view monitoring system and those of the black box. In this system, location information which is not provided by the existing AVM systems of automotive companies is added to the around view monitoring system based on Car PC by way of using a USB GPS receiver with which location information and speed can be detected. This study has implemented an image storing system in which latitude, longitude and speed information are detected by using the RMC sentence summarizing the minimum data of GPS through the GPS receiver, and images from four cameras are input and synthesized and then, saved altogether with location and speed information in the storing device.

Design and Implementation of a Diagnostic System for MOST Network using Wireless LAN

According to increase of the number of electronic devices for user comfort and safety, electronic systems are being constructed by using network to effectively control the devices. In this paper, we design and implement the MOST network diagnostic system by using wireless LAN to diagnose MOST network and the devices connected by the network and to effectively manage them. MOST, which is a vehicle multimedia network standard for the next generation, is being used for construction of car infotainment systems, and enables to develop various devices which are required for them. The wireless diagnostic system implemented in this paper enables to self-diagnose MOST network and also to check errors by diagnosing status of MOST electronic devices. We also can check and manage status of a in-vehicle MOST network system using mobile devices based on wireless LAN.

Design and Implementation of Channel Allocation Module of Synchronous Area in MOST Network

While MOST is an in-vehicle network which transfers concurrently synchronous data, asynchronous data and control data, it provides high bandwidth synchronous section which can transfer video and audio without buffering. To transfer real time data using synchronous section, connections between source node and sink node, and channel allocation for connections are required. In this paper, we proposed synchronous data transfer method and channel allocation method by constructing MOST network after designing and implementing channel allocation module for using synchronous data section.
