摘要

由於機車的後裝市場近幾年推出全取代/外掛式供油電腦，讓有特殊需求的駕駛可以進一步的提升車輛的性能。但目前不論是全取代還是外掛式供油電腦，其設定的介面均透過有線方式(Recommended Standard-232, RS232)設定供油模式。換句話說，每次設定都被限制在一定距離內，也無法即時得知正在行駛的車況，與其細部的引擎狀態工作狀況。此外，在道路行駛時，若是發生突發狀況，亟需一些車上維修資訊或是當地資訊的迫切服務。

因此，本研究於機車加裝外掛式供油電腦與OBDII(On-Board Diagnostics-II)車輛檢測單元，並從CAN(Controller Area Network)車載網路中獲取車輛資訊。此外，以智慧型平板電腦為使用平台開發一款應用程式來設定供油模式與了解車況。當機車在外地沒油或故障時，系統透過G3(GPS、GIS、3G)與LBS(Location-Based Service)尋找最近的維修站/加油站，並請求協助。其中，G3為本研究同時採用GPS、3G與GIS(Geographic Information System)等協定所整合出的系統功能，並提供使用者最佳的車輛診斷與適地性服務。

最後，經實際道路測試，本研究不僅可以整合與改變原廠噴油時間、車輛故障原因與車輛即時狀態，更能提供駕駛更完整的診斷服務與駕駛樂趣。

In recent years, the reconstruction of motorcycle market has launched a full replacement / Plug-in Fuel & Ignition Sub-computer system for improving riding performance and meeting drivers specific needs. No matter it is a full replacement or a Plug-in Fuel & Ignition Sub-computer system, its settings are made with a wired interface (RS232) to set its fuel injection duration. In other words, each set is confined within a certain distance and can not readily sense vehicle’s conditions or detail information of the engine operating condition when a vehicle is moving.
In this study, the main purpose is to develop the plug-in fuel & ignition sub-computer and the OBDII (On-Board Diagnostics-II) vehicle detector on scooters so that both drivers and technicians’ can get the information concerning the vehicle conditions from the CAN Bus network(Controller Area Network). Moreover, with a further developed tablet app, drivers can set the fuel injection duration and acquire the immediate vehicle conditions. When the scooters were running out of fuel in strange places, the system can provide the nearest service station / gas station for drivers to ask for assistance via the G3(GPS、GIS、3G) and the LBS(Location-Based Service). G3 is a designed network system that integrated GPS、3G and GIS(Geographic Information System) protocols to assist riders to diagnosis the real-time vehicle condition and to provide a useful and adaptive location-base service.
The designed embedded vehicle diagnosis system with G3 and location based service not only provide real-time vehicle operation condition for users, but also enhance the drivers convenience with location-based service information.
