| Summary: | 碩士 === 國立臺北科技大學 === 機械工程系機電整合碩士班 === 106 === The volume of transportation is booming as large quantities and different kinds of vehicles moving on the road to fulfill the needs so that importance of transportation safety and protection becomes an issue in modern society. The causes of most traffic accidents on the road can be identified as diversion of drivers fatigue, intoxication or ignorance, which renders the vehicle safety augmentation systems as inevitable and important functions for the development of modern vehicles. While improving the efficiency of developing the fore-mentioned vehicle safety systems, to lower the cost and risk of development and testing, this study utilizes a vehicle driving simulator to design an active or augmented safety system. That is, to analyze the vehicle dynamics and the lane keeping assist system with the help of virtual reality and simulation. To accomplish the design, testing and simulation in this study, besides the existing vehicle simulator, a micro-controller based torque sensing and torque servo control is developed along with the simulation facility to validate the developed lane keeping assist system. This study also established the functionalities and procedures for developing the advanced driver-assistance systems(ADAS) in the real-time vehicle driving simulator which will be a safe and cost-efficient testing environment for practical system development as well as theoretical verification. In this study, the lane keeping assist system developed with driving simulation was been tested in straight road.The augmented LKAS vehicle control system achieves a steady-state lateral error of less than 5 cm and a transinet lateral G value of less than 0.2G.
