Throttle Command to Torque Command

Hello Everyone,

I am setting up a longitudinal motorcycle model using the mapped engine available in the Powertrain Blockset. The engine maps that I have are in the form of X: RPM, Y:Throttle_Positition_% & Z:Torque.

The Mapped Engine block in Simulink requires Torque_commands instead of Throttle_Position.

How can I convert my Throttle_position based engine maps to Torque command based?

Many thanks.

Hi @Tamas

Can you possibly find out the formula or relationship between the Throttle_position and the Torque_command?

If you don't have that, then try:

kp             =   1;                   % Proportional Gain
Torque_command = - kp*Throttle_position;

The Proportional Gain should be a positive value that you can mathematically calculate it (if you understand the physics) or tune it according to some objectives (if you don't know what value to put in).
