6.1.1.4. gear_box

It contains functions that model the basic mechanics of the gear box.

Sub-Modules:

thermal It contains functions to calculate torque losses and the gear box temperature.
at_gear It contains functions to predict the A/T gear shifting.
cvt It contains functions that model the basic mechanics of a CVT.
mechanical It contains functions that model the basic mechanics of the gear box.
