Recently, various services using road-vehicle communications have been put to practical use, and information on the running history and performancedata of the vehicle is uploaded to the roadside and expanded to services that use it in addition to the information delivery from the roadside to the vehicle. The "in-vehicle information terminal" interfaces with the car navigation system and the electrical equipment control system after it meets intelligent transportation system (ITS) on-board unit Dedicated Short Range Communication (DSRC) standards. This terminal also mounts functions for observing the state of the vehicle and controlling the vehicle remotelyfrom the roadside by DSRC. In this project, the protocol that connects the roadside with the in-vehicle network was developed. Additionally the in-vehicle information terminal and the roadside system were developed, whichachieved reading and writing of vehicle data via DSRC and Controller AreaNetwork (CAN). Moreover, "car security" was created as a DSRC applicationservice, an experimental system was developed, and the usefulness of the service was evaluated.
