ZEROSHIFT AUTOMATED MANUAL TRANSMISSION (AMT)

INTRODUCTION

The world is dominated by two forms of transmission, the manual transmission (MT) and the Automatic Transmission   (AT). The MT has a single dry clutch operated by the driver whilst the AT uses wet clutches that are automatically controlled. There are pros and cons to both transmissions. The MT is the most efficient trans6 or 7 speed AT6 or 7 speed AT6 or 7 speed AT transmission available. This lends itself to providing good fuel economy for the vehicles it is employed in. The efficiency of the MT is dependent on the load applied. Over a representative drive cycle its efficiency can approach 97% .   The MT is very easy to manufacture having very few parts. It is reliable and easy to maintain. Its main weakness is that it is less easy to drive than an AT especially in congested traffic as it requires the driver to operate the clutch for each gear shift. Gear shifts are sometimes not smooth which causes discomfort for passengers who will notice an interruption of engine torque to the wheels when the transmission is between gears. In severe situations the interruption of torque can cause dynamic instability of the vehicle resulting in loss of control. The AT has many advantages which include ease of driving and very smooth shift quality. The choice of gear is determined by a transmission control unit (TCU) and this will ensure that the...
