Matlab: computeThreshold(engine speed, throttle)

https://www.mathworks.com/help/simulink/examples/modeling-an-automatic-transmission-controller.html

Engine speed: RPM 

Throttle position: % 

Upper threshold: cross point between this and next gear final torque (usually redline, if for maximum acceleration) 

Lower threshold: least final torque drivability required

DP: 

  • Fuel optimal

  • Drivability optimal

Key concepts: 

  • Engine Torque Map

  • Drivability: torque reserve
