A Study on Speech-Controlled Real-Time Remote Vehicle On-Board Diagnostic System

This paper proposed a speech-controlled real-time remote vehicle on-board diagnostic (OBD) system for telematics applications. The proposed system contains three main parts. They are OBD embedded global position system (GPS-OBD) module, speech-controlled interface, and vehicle surveillance server. In addition to the real-time vehicle time-location information including date, time, longitude, and latitude obtained from GPS receiver, the GPS-OBD module can also record the real-time vehicle operation information including vehicle speed, engine rpm, coolant temperature, battery voltage, fault code number, and others from OBD system. These real-time vehicle data, i.e., vehicle time-location and operation information, will be uploaded to the vehicle surveillance server via 3.5G network. Meanwhile, the GPS-OBD module can be operated through the speech-controlled interface. The derivers therefore could safely operate the proposed system via speech commands and keep their eyes on the road. The vehicle surveillance server is designed to provide real-time vehicle information retrieve service for authorized supervisors or servicemen. One can use a specific browser co-operated with Google Maps to retrieve real-time vehicle information, e.g., date, time, speed, vehicle location, and etc of the monitored vehicle. The proposed system is very useful for the detection of vehicle pollution, warning of vehicle malfunction, remote diagnosis, and roadside repair.
