Performance Analysis of an Automated Manual Transmission Controller for Two-wheeler 2019-28-0125
This research paper presents controller development and performance analysis for the two-wheeler. The comparison for different performance parameters is carried out with and without automated manual transmission (AMT) controller. The AMT considered, in this case, includes a conventional manual transmission gear-box with a conventional clutch pedal. It is equipped with clutch actuation with the help of linear actuator and the gear shifting using a servo motor. The upshift and downshifting of the gears and the clutch actuation is done through the decisions of the controller. The results generated during the engine dynamometer test are used as input creating a two-wheeler vehicle model using AVL cruise software. This vehicle model is used to predict vehicle performance. These vehicle performance results are validated with chassis dynamometer test data. The vehicle model is modified for the generation of gear shifting plot. AlsoGear shift program (GSP) is generated using the GSP generation module of AVL cruise software. The two criteria used for GSP generation are fuel economy and vehicle acceleration performance. The simulation results include generation of gear shifting graph which covers range from 0-120 kmph. The hysteresis zones are established during upshift and downshift, based on actuator and sensor limitations. The automated manual transmission control algorithm has used the input of two parameters which are vehicle speed and throttle position.
