碩士 === 華梵大學 === 機電工程學系博碩專班 === 98 === The principle of this essay mainly focuses on applying ultra-sonic sensors and voice notifying techniques to design and build a feedback control system, which is intended to assist drivers in parallel parking vehicle properly. The mainframe of this system integrates an ultra-sonic sensing module, a module of voice-notifying circuits and a micro-processor, namely AT89C51ED2, to monitor the whole parking actions. In this study, we adopt feedback control mechanisms and apply ultra-sonic devices to measure the distances between the vehicle and the surroundings. Through fuzzy control theories, we implemented fuzzy control procedures, and then enhanced the reference mechanism with practically acquired data to construct an expert database. Therefore, via testers’ driving experiences and tests, we replace the fuzzy control approach with the expert database and accomplish the feedback control mechanism for the voice-assisting parallel parking system. Keywords: Ultrasonic sensors, parallel parking system, fuzzy control, expert system, voice-assisting.
