This paper present the unified gateway for in-vehicle network using LIN, CAN and FlexRay. The presented gateway uses MPC5567 MCU including LIN, CAN and Flexray communication controllers. In this paper, we propose the reliable gateway algorithm and architecture. Also, an embedded system for gateway is developed and gateway function is implemented. The proposed system is evaluated by several experiments under a HEV test-bench environment.

Korean households are gradually changing from a large family to a single family. The way in which products are sold according to the characteristics of one person is also changing. However, IoT products still do not reflect the characteristics of a single licensee. In particular, the younger generation is at a higher risk of fire due to the shorter residence time of the family. In this study, we designed IoT gas valve to detect gas and flame using RaspberryPi2.

As increasing the number of Electronic Control Units in a vehicle, the proportion for reliability and stability of the software is going increasingly. Accordingly, the traditional CAN network has occurred the situation that the requirement of developing vehicle software is not sufficient. To solve these problems, the FlexRay network which is ensured the high bandwidth and real-time is generated. However it is difficult to implement FlexRay based application software because of complex protocol than traditional CAN network. Accordingly the system for analysis and verification of network state is needed. Also vehicle vendor develops application software using Matlab/Simulink in order to increase productivity. But this development method is hard to solve the network problem of node to node. Therefore this paper implements Matlab/Simulink based FlexRay network system and verifies it through comparing with existing embedded system.

This paper deals with an embedded system that are based on Electronic Control Unit(ECU) course for an automotive engineer. The embedded system that uses the Freescale HCS12 microcontroller that is currently used for body control ECU. It is made for practical training and includes various peripherals, such as LED, sensor, motor, communication port. The students of this course can learn the various functions of HCS12 and the way of using the peripherals. Moreover, this course deals with the in-vehicle networks which are Controller Area Network (CAN), Local Interconnect Network (LIN). Therefore the students can apply the experience of practical training to real application that used ECUs and in-vehicle network. This paper described a schedule of the course and the contents of practice. As the survey of students’ opinion, we propose more advanced embedded system course for automotive engineers than this course in order to help the automotive engineer to make the based knowledge for applying to real automotive application.
