Because of the high efficiency in the MT system, MT systems are popularly used in vehicles. But it is found that power shock exists due to shifting with incorrect timing while a MT system is shifting. Such a problem makes drivers exhausted in driving. Therefore, automatic transmission system has gradually replaced MT system in passenger cars and some other vehicles. However, an AT system generally has 7% less transmission efficiency and 30% higher cost than those for a MT system. Thus an automatic manual transmission (AMT) system is the key to solve such problems. AMT system is adding functions of automatic clutch and gear-shifting to the traditional manual transmission system. The main parts in AMT system include automatic clutch, gear box and electric control system. The transmission control unit (TCU) in AMT system controls the functions of clutch engaging, gear shifting and fuel throttling by electrics or hydraulics. TCU also decides the optimal gear-shifting by vehicle speed and throttle opening to make the vehicle having smooth speed and power output in the transition of gear shifting. With the aid of AMT system, a vehicle can have higher transmission efficiency, lower fuel consumption, and higher driving comfort. 蕭耀榮 2007 學位論文 ; thesis 82 zh-TW |

The main parts in AMT system include automatic clutch, gear box and electric control system. The transmission control unit (TCU) in AMT system controls the functions of clutch engaging, gear shifting and fuel throttling by electrics or hydraulics.

With the aid of AMT system, a vehicle can have higher transmission efficiency, lower fuel consumption, and higher driving comfort.
