Solved How to find gearbox RPM?

I know that a gearbox has its own distinct RPM value, but how can this value be obtained and used in lua?

 

Gearbox RPM is dependent on the gear and ratio I believe. It's the RPM that the transmission is rotating at, unlike engine RPM which is the RPM the crankshaft is rotating at.

 

pretty sure it's engine RPM/gearRatio
wheel RPM would be gearbox RPM/finalDrive

 

Have you looked into steamapps\common\BeamNG.drive\ui\modules\apps\PowerTrainDebug\app.js ?

That is responsible of showing gearbox rpm in powertrain app I believe.

 

This is what I found:

Code:

        var textItems = []
        if(e && e.av) {
          textItems.push('RPM: ' + Math.round(e.av * 9.549296596425384)); // AV to RPM: 9.549296596425384
        }

This is a general code, used for everything (engine, gearbox, and so on).

I'm not sure how to directly obtain the RPM of the gearbox.

 

Gearbox RPM, like output of TC or Clutch or RPM like Output?

Sadly I don't know such, but writing dump(powertrain) to console gives me quite a lot of all kind of words and numbers, from log file one might be able to find some new things to try, maybe?

Code:

 90.23750|A|libbeamng.lua.V.lua.utils|            inputAV = 73.813966487609,

 90.23753|A|libbeamng.lua.V.lua.utils|            isPhysicallyDisconnected = false,
 90.23754|A|libbeamng.lua.V.lua.utils|            isPropulsed = true,

 

So from dump above I can see:
90.23718|A|libbeamng.lua.V.lua.utils| name = "gearbox",
90.23734|A|libbeamng.lua.V.lua.utils| outputAV1 = 35.127011032104,

I guess logic to get unknown is like this:
powertrain.getDevice("gearbox").outputAV1

So with same logic wanting to know torque of box would be:
powertrain.getDevice("gearbox").outputTorque1

Maybe that bit is useful for someone at sometime in a future.

 

Thanks for the help, it worked
