Study of Optimum Gear Ratio Selection and Gear Shift Strategy for Automated Manual Transmission for Two Wheelers 2015-01-1089
Transmission is the drive line of a vehicle. Road load requirement are fulfilled by transmission system. Selection of gear ratios in early stage of design based on simulated vehicle performance reduces the cost and time in product design cycle. Selection of gear ratios based on acceleration performance in 1st and 2nd gear, maximum speed of vehicle achieved in last gear and grade-ability in first gear is explained in this paper for AMT. Automated manual transmission is a recent trend in two wheelers that fulfills fuel economy requirement and increases driving comfort. Gear shift strategy for AMT is derived based on fuel economy or drivability. This paper addresses the shift strategy that targets drivability of vehicle. Simulation done in GT power is done with India driving cycle to derive gear number against vehicle speed.
