Engine Start/Stop button logic

[dzzr]

Hi all,

Does anyone have some tips or example on how to setup the logic for a single engine Start/Stop button on a keypad?

I have the start side of things working perfectly (press and hold button to start). I also have built in checks to the start function like running status using RPM input over CAN.

With the engine running I would like to momentary push the Start/Stop button which will set the ignition coils output to false, until RPM=0 for say 2 seconds, then switch the ignition coils back on automatically ready to start again.

Not sure if I should be using a toggle/set-reset on the ignition coil output or a combination of both with a Engine.Stop function?

Thanks!

Hi,

Can you post the current PDM config that you have thanks, this will make it easier for solutions to be offered.

With the coils, I would advise against having them powered if the engine is not running, especially if there is a chance that the ECU could be depowered with the coils still powered.

I haven't tested yet but, could this do the trick? Seems to make sense to me but might be missing something obvious

Hey all,

I never got this figured out. My attempt didn't work

Anyone got any ideas?

Give below a try. I changed your Engine Kill Function to pulse on the rising edge of the start button. The pulse is shorter than the delay of Engine Running so that when you are actually starting the engine it doesn't also trigger the stop.

There is an added Engine Kill Pulse function which pulses for 2 seconds when the Engine Kill function becomes true. This function is used in the output.

Thanks Adrian! It worked perfectly
