摘要

本研究針對傳統車輛使用的整車線路，提出一個整合型控制模組的概念；此模組包含了車輛燈光、喇叭、起動、故障診斷、CAN Bus通訊系統。整合型控制模組的概念是將車輛燈光、喇叭、啟動開關信號與作動器集中整合，經由微控制器控制各組件的作動。並加入故障診斷系統與控制器區域網路匯流排通訊協定，作為模組監測及系統間資料傳輸之用途，藉此提升系統的安全性及達到整車線路精簡化的目的，減少車輛的製造成本與車體重量。系統實驗平台部分，本研究以Microchip微控制器(Micro Control Unit簡稱MCU) PIC18F66K80來設計，透過微控制器的可程式化與高應用性來設計本控制模組。將開關信號集中至整合型控制模組，並使用MCU PIC18F66K80於控制器中做控制，透過整合型控制模組做電源輸出，使電路不須再經由開關輸出，以減少電線的使用量。電源控制採用半導體取代傳統繼電器，減少模組體積與成本並延長使用壽命。並加入燈泡診斷電路，讓駕駛者隨時掌握車輛狀況，增加行車安全。最後，採用控制器區域網路匯流排通訊協定作為通訊介面，並符合SAE J1939的規範，讓此模組能透過控制器區域網路匯流排通訊系統與符合相同規範的設備與系統，相互傳輸資料或診斷、控制此模組，藉此達到系統整合及精簡線路之目的。

It is mainly for conventional vehicle harness, this thesis proposes a concept of the integrated control module. This module contains vehicular lights, horn, starter, fault diagnosis and CAN BUS communication system. This concept is that a module integrates the switching signals and actuators which are controlled by a microcontroller. Furthermore, the fault diagnosis and the CAN Bus protocol are used in this system to transmit/receive data between each device and the fault diagnosis. In this study, a Microchip MCU (Micro Control Unit) PIC18F66K80 is used in this system to implement the integrated control which integrates switching signals and actuator assembly to the module. In this system, the relays are replaced by the MOSFETs to reduce harness, volume and extend lifetime. Besides, the lamp fault diagnosis circuit is included in this system which the driver could handle the vehicular states at any time. Finally, this system uses the CAN Bus protocol to meet SAE J1939 regulation. By the CAN Bus communication, this system could transmit/receive the data to the equipment; the equipment could diagnose and control this system. In this study, the purpose of integrated and reduction of harness could be reached by the implementation of this system.
