碩士 === 國立屏東科技大學 === 車輛工程系所 === 101 === Taiwan Environmental Protection Administration (EPA) has been released a policy for scooters, in which certain percentage of scooters manufactured or sold in Taiwan have to achieve zero idle emission, i.e. CO=0% and HC=0ppm. According to the policy, electric scooters, hybrid electric scooters, and gasoline engine scooters with automatic Idle Start-and-Go system (ASG) are all acceptable. One of the important technology for the development of Taiwan's scooter Industry, ASG control system can automatically order the engine stalling and re-starting command by according to the signals of sensors mounted in vehicle. This study investigated the feasibility of ASG system without human intervention, The objective of this study is that using CPLD chip as the control core, design can be applied to the controller on real road. Develop the control logic algorithm and peripheral circuits of ASG control module by means of analysis of driving behavior on scooter and security. The results of this study to CPLD chip to control the core of ASG module. ASG modules installed on a four-stroke EFI 50c.c engine scooter, proceed actual road test for verifying the feasibility and reliability of ASG control technology. Experimental results show that：(1)The ASG system can according to the sensing signal automation stop and start command.(2)The ASG system supported by robust ,there will not be the mistake of start or stop resulted from the driver’s incorrect operating (3)With the control logic,the situation of repeated start and stop caused by the traffic in urban areas can be avoided.(4)The start-up time compared with the origin was improved by 21%,since quick start strategy is added into the ASG system.
