Abstract

This paper proposes a remote diagnostic protocol and system for U-Car, which has same functionality of conventional scanners, automobile diagnostic instruments. It consists of a remote server, mobile handsets with an application and a connecting device. The remote server has vehicle diagnostic database. The application program on mobile handsets relays diagnostic signals and controls the flow of data packets based on the dedicated protocol. The connecting device is used for converting the signal level and protocols between automobiles and handsets. Since the remote server diagnoses vehicle directly, diagnostic history can be accumulated automatically. Therefore, value added services such as connecting service-shop directly based on diagnostic results are possible. New automobile systems can be easily dealt only by changing diagnostic database of the remote server. Although the proposed system is constructed based on mobile handsets, it can be easily extended to car-PCs and other systems for U-car.
