Semi-automatic transmission is a
system that makes use of electronic sensors, processors and actuators
for gear shifting. The system removes the need of a clutch pedal
required for gear changing. This system is widely used in the automobile
industry.
Types of Semi Automatic Transmission
- Direct Shift Gearbox
- Dual Clutch Gearbox
The system allows for only forward and backward shift into higher
and lower gears. It does not make use of the traditional H-pattern,
normally used in automobiles. The system is also equipped with sensors
that sense the direction of the shift. The input combines with the
sensor placed in the gearbox and senses the current speed and selected
gear. The unit also determines the torque required for smooth
functioning. The system also reduces fuel consumption significantly.
