Abstract: Drivers are becoming more fatigued and uncomfortable as traffic densities increase, and so, can show slower reaction time. They then face the danger of traffic accidents due to their inability to cope with frequent shifting. To reduce this risk, some drivers prefer automatic transmissions to manual transmissions. However, automatic transmission requires both higher fuel consumptions and costs. For this reason, attention to automated manual transmission that can provide high efficiency, low cost and easy manufacturability has been increasing. In addition, the function and performance of the electronic control unit of automobiles has improved continually and rapidly with the growing electronics technology. The ECU is a representative embedded system in automobiles, which has to satisfy high performance and reliability under the constraints of size and cost. In this paper, the embedded system platform for automobiles is developed on the basis of MPC565, and a test rig is developed to perform the basic function test for automatic clutch actuation. The developed embedded system and clutch control algorithm are validated by the experimental results performed on the test rig.
