碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 99 === In recent years, to enhance automotive performance, safety and comfortableness, automotive electronics manufacturers have continued to thoroughly develop various electronic control devices, CAN Bus data communications can perform data transmission issues among devices, and simplify signals or transmission wiring. This paper presents a driving recording system (or tachograph) to coordinate with the trend in vehicle network systems and driving recording system into CAN Bus. It could record on-road driving data and meet the requirement in all commercial vehicle families. The tachograph main controller NXP LPC1768 is a 100-Pin TQFP package that includes data acquisition module (impulse signal and CAN-Bus data), LCD display module (LCD and button), data record module (EEPROM and IC card), beeper and M-150Ⅱ micro-printer module then output the driver and driving information. The driving recording system developed in this study can capture, store and protect the related information, provide the driver and automobile management system to perform analysis. The driving recording system developed in this study may serve as a reference to the driving recorder manufacturers. This system can record any driving information when the car accident occurred. It also can be an evidence for judging the accident. This system is worth to develop and apply widely. Hence, due to its simplicity in hardware structure, low cost, customized installation and reconfiguration, and excellent feasibility, the tachometer is expected to offer a significant contribution to vehicle communication and information system.
