Gear Shifting Control for Pure Electric Vehicle with Inverse-AMT

Abstract

In this study, the gear shifting control strategy for pure electric vehicle with inverse automated manual transmission (I-AMT) is proposed. Based on a new drive train system of pure electric vehicle, an AMESim model of vehicle drive-train system is set up. Through the precise control of sliding sleeve, clutch engagement and separating time, gear shifting process is realized without driving torque interruption. The results show that, during up and down shift process, the driving torque keeps more than 50%, obviously improve the pure electric vehicle accelerating performance and the ability to climb.
