Throttle body modeling and simulation

AI Thread Summary
The discussion focuses on modeling a throttle body in Simulink and how to connect the gas pedal's position to the throttle actuator. The user seeks guidance on converting the gas pedal's push force into a position that can be translated into an angle for the ECU. Suggestions include using the "ANGLE TO VOLTAGE" block and exploring methods like look-up tables or signal generators for variable input. Resources from MathWorks are recommended for further assistance. The conversation emphasizes the need for a clear connection between the gas pedal input and the throttle response in the simulation.

I modeled a throttle body in Simulink. How do I model the position of the gas pedal so that if the position of the gas pedal changes the input voltage to the throttle body actuator will change and open the throttle? why should i give on the left side to get position of the gas pedal from the potentiometer sensor?

Yes. Using a HUGE font is screaming.
 
The signal you are asking about connects to the block "ANGLE TO VOLTAGE." Look at the documentation for that block and use what it says is expected for input.

yes I understand that. my question was how do I model the gas pedal to be an input? that means the position change of the gas pedal by the press from the driver will be converted to angles and sent to the ECU. then the ECUwill sent a voltage equivalent to it to the throttle actuator. so to be specific I need how the push force of the driver to be changed to position of the gas pedal...
 
Ahh, OK.

Unfortunately I'm not familiar with Simulink, but there is probably a way of telling it to 'Sweep' a variable over a range. Their method may be a look-up table, or a signal generator, or a loop construct of some sort as in a 'For Loop.'

I found this page at the Simulink supplier (mathworks.com) that may help find the answer.

If that doesn't work try this.
