A Practice Learning of On-Board Diagnosis (OBD) Implementations with Embedded Systems


This study presents the impact of embedded system on the development of on-board diagnostics (OBD) implemented by engineering students. The engineering students need professional skills in engineering design for their future related works. We design a practice course to train students to integrate discipline-specific components into embedded systems and learn the subject-matter deeper through a vertical integration. Focusing on a specific and multi-disciplinary design project gives the students a helpful train to apply design principles, but they have difficulties in absorbing what they have learned and applying their learning to other projects. This course encourages students to integrate different and related knowledge into experiments, and it provides students training on the design details of OBD, electric circuit design, and embedded system. We designs a practical implementation course to teach multi-disciplinary skills of vehicle electronics in the OBD implementation based on embedded system. The study uses pre-test and post-test to examine the impact of the experiments. Most graduate students in vehicle engineering participated in the whole of this exercise. From the results of test, we can see that students have significant improvement on every concept category in this course, and students’ responses are generally very positive.


The vehicle production is an important force to push automotive industry forward. With the growth of vehicle production and consumer electronics, vehicle electronics become a recently highlighted topic in the automotive industry and need more trained engineers. These engineers need both vehicle and electronic knowledge, and require hands-on experiences of embedded system. For this they need a solid basic research background, applied R&D basis, innovation of marketable products and services. However, the curricula of vehicle electronics have not kept pace with the demands for vehicle electronic engineers, especially OBD engineers. The practical training of OBD implementation based on embedded system is often insufficient for vehicle engineering students.

Over the past few years we have been engaging in the study of student learning on embedded processors since MOE Subsidy Operational Guidelines for Advance System on Chip. This idea came from a teaching request, which is a material of experiments in an embedded system course needed by one of authors. We developed a material of embedded system applied on vehicle electronics. The vehicle electronics course is difficult to be developed, because the knowledge of it is related to electric circuit, sensors, hardware, and embedded software.

To minimize the gap between theory and practical implementation, this study designed a practical implementation course by integrating discipline-specific components. In this study we have developed an OBD implementation courses that consist of OBD concept, interpreter circuit, and embedded system. The course provides students trainings on the OBD design and comprehensive hands-on practices on embedded system. The experiments of this course require students to build and analyze embedded systems, and ask students to combine various components from different concepts. The educational objectives are as follows:

• Enhance students' thinking skills.
