AMT Reverse Gear Engagement Dynamics and Control. 2019-26-0046

Now a day’s automated manual transmissions (AMT) are getting popular because of hassle-free gear shifting and improved fuel economy. OEMs are talking about converting their existing manual gearbox to AMT gearbox with solution like hydraulic or electric AMT kit, which just replaces the manual shift mechanism converting it to AMT. Generally, in manual gear box, the operational principal of reverse gear is sliding mesh. Due to sliding mesh, gear arrangement can creates interruption for gearshift. In this paper, reverse gear shift process and its operational difficulty at different operating condition has been studied and analysed in detail. Based on status of vehicle, to ease the gearshift, optimized flow process is proposed. The control method that increases probability of smooth and quick shifting in all operating condition is discussed in detail. The developed control model has been in implemented on real vehicle and it results are discussed.
