This paper is an introduction to the opportunities, challenges and technical solutions chosen for implementation of an electronic throttle control (ETC) system on a 50cc 2-stroke scooter.
The paper outlines the selection of the ETC motor and the choice of the throttle position sensing (TPS) system along with the development of a new twin sensor throttle demand (TDS) twist grip, and briefly describes the benefits achieved in fuel economy, electronic vehicle speed control, improved start-up and idle stability.
The ETC software operational strategy; including start flare, idle speed control and vehicle speed control are presented as real world strategies to achieve 22% improvements in fuel economy and accurate electronic vehicle speed control.
