Can anyone help me to interpreter the raw CAN bus data for the following items?
• Brake pedal pressure
• Gas pedal pressure
• Steering wheel angle
• Steering wheel momentum
every vehicle is going to be unique. Car mfg’s dont use universal CAN message framing for non-EPA/SAE stuff…
You’ll have to find all that stuff by yourself.
Plug the Macchina in and log the bus…actuate the accelerator pedal, steering, etc, and see which bytes move in unison…
Thanks! Now I know which bytes are representing which value. I am wondering how to interpret HEX to decimal and what would be the conversion rate and unit.
Again, completely depends on the manufacturer and how they decided to setup the CAN framing…
Could be an 8-bit value, could be a 16 bit value, etc.
You’ll have to watch the bus readings, and do some math to figure it out.
