Gear Shifter
Automatic Gear Shifter Component
The Gear Shifter component automatically changes the gear for use with various gearboxes in the Driveline Component Library. The gear number (output) is incremented by 1 when the engine RPM (input) passes the upper threshold (). Similarly, when the engine RPM goes below the lower threshold (), the gear number is decremented by 1.
Note: To avoid multiple gear shifts due to small variations in the engine RPM, pass the input signal through a Lowpass Butterworth filter first.
