抄録(英) | Introduction of 2-speed transmissions into EVs can improve cruising range and driving performance. There are two requirements for 2-speed transmissions in EVs; 1) large step ratio to maximize cruising range and 2) compactness to be comparable to fixed-ratio eAxle in mountability. Shifting in large-step-ratio transmission causes severe shock deteriorating driving comfort. This paper proposes a 2-speed transmission with a magnetostrictive torque sensor for robust seamless shifting. Feedback control with the output torque sensor makes seamless shifting possible without tuning of controller parameters. Moreover, we propose a multifunctional shifting device using a single electric actuator to downsize 2-speed eAxle. The advantages of the developed 2-speed transmission are verified through seamless shifting experiments. 翻訳 |
