碩士 === 國立臺灣海洋大學 === 電機工程學系 === 104 === Mobile broadband network, smart device technologies, and the concept of cloud computing have become growingly mature. As a result, software requirements of connected car systems are no longer limited to monitoring and static scheduling and dispatch, and now involve the integration of multiple information systems, including dynamic scheduling, dispatch, information exchange, and interactive services added to the background management system and the in-vehicle system. This massive and complex system requires a good framework and system approach; otherwise severe issues might occur with the overall performance or program architecture. At first, this might cause system overload and failure, impacting the operation of the entire fleet. Even worse, it might cause the fleet to sustain loss, which is the least desired outcome when designing the system. This study mainly implements a front-end management system for connected cars, and combines it with a background webpage management system, integrating the system with Dropbox for multimedia streaming, so as to provide image browsing, music, and video functions. The connected car system not only provides more entertainment functions for the in-vehicle system, but also has smart mobile computing and sensor functions for information on orders, vehicle status, and traffic conditions. The front-end management system uses GPS to gain information on the current location and speed, and provides the information for the background system to update vehicle information and location. This allows the background system to analyze the status of the entire fleet and more efficiently dispatch vehicles. Once a connected car receives the location it is being dispatched to, it uses Google Maps to plan an accurate route to the destination, also providing traffic broadcasting, speeding warning, time warning, and video recording of inside the vehicle. These functions mainly serve to make vehicles drive more efficiently and safer. In the past, the Internet of Vehicles emphasized vehicle dispatch, but new services were gradually developed following technological developments. Besides improving the existing dispatch function, vehicle status monitoring, warning and reminders, and multimedia functions were added to make the connected car system more complete.
