Hello everyone !
I have as a project to create a car simulation inside of UE4. So far so good, I have suspensions working, alongside with wheels spining & direction.
I would like to know what would be the most realistic way of making the car accelerate. I have read a bunch of post all around the internet, but never found answers to my questions. So here I am. Basically, I know that I can approximate acceleration with my 0-1 value of throttle (1 being maxium RPM the engine can handle), but, correct me if I'm wrong, in a real car, pressing the pedal to the max does not, in fact, make the engine rev at it's highest point. It increase the speed at wich the engine rev. If my gas pedal is pressed at 1/10 of it's full course, with no gear engaged, it will make the engine go to it's highest point, but slowly. Instead, if i pressed my gas pedal to 8/10 of its full course, I will "accelerate" my engine faster.
So my question is how to simulate this the most accuretly possible ? Let start with this, without speaking about gear, friction and loss. Basically, I'm in neutral, and press my gas pedal. How would you simulate this behavior ?
If anyone is interested in seeing how this project goes, i'll post updates on my youtube channel, and a quick preview of what I already have can be found here : https://youtu.be/dCdARHeV3Tk.
