Electronic Gear Control Unit For Automated Manual Transmission (AMT)

An electronic gear control unit allows a fully automatic gear change to be made with a manual gearbox; the unit is usually directly mounted on top of the gearbox. The electronic gear control unit is a combination of mechanical components (e.g. pneumatic cylinders) as well as electrical components (e.g. solenoid valves, cables, electronic control units).
Due to the integration of several functions, today�s automated manual transmission (AMT) modules reach an enormous degree of complexity. An AMT is the basis for the improvement of the driving comfort and the reduction of the load of the driver. The driver is able to focus his attention on the road traffic; there is no need to concentrate on the gear selection and gear shift process any more. The use of an optimized gear shift strategy (selected by the system and based on the driving situation), means that AMT can significantly reduce fuel consumption and mechanical wear in e.g. tractortrailer couplings when compared with conventional manual gear box operation.
