Tesla parking brake

Hello everyone, how did you do it with the electronic parking brake? I have installed the entire Tesla rear axle, now I control the parking brake via an Arduino and a button, since when the inverter is switched on there are problems and the parking brake reacts, I have done it for safety reasons so that you can only control the brake when the inverter is off, is there a better solution?

What problems and what kind of reaction?
These should be two separate and independent systems.
In my view one could want to enable the parking brake and yet leave the car on.
I'd say 'bake pedal pressed' is a nice prerequisite of operating the electric parking brake.
That's how I do it in my parking brake controller.

Hi, so I use the Pololu VNH5019 shield on Arduino Uno, when I use the parking brake with the ignition and then start the inverter, the parking brake motors rotate for a short time, which is why I switched the power supply of the Pololu so that it is only supplied with power when the main relay to the inverter is open, for safety reasons, so that the parking brake does not trigger due to possible faults, which controller do you use, the idea with the brake pedal is pretty good, so the controller would only be supplied with power when the brake pedal is pressed, which is also the case when driving, the best solution would of course be a standalone controller with a CAN bus connection, and then control it via VCU, since the status is available and can only be operated when the vehicle is stationary
