Need an On/Off Switch That Will Operate Only When the Vehicle is in Motion

[BBShark]

I am working on door panels that "merge" C6 panels to work on a C3. The C6 panels have an electric latch for the door that is operated by a push button. I have the electric latch worked out.

I assume (could be wrong), that the C6 has some type of motion activated switch that that disables the door latch switch. Although I think the chances are remote, I'm kind of concerned that a passenger could push the button while the car is in motion.

The requirements for this switch is that it has to be able to sense that the car is in motion but not stopped (or coasting in idle). So probably no vacuum switching. I'm thinking a RPM switch? I do have a VSS but it controls the speedometer and you can't split the signal.

Speed Switch Relay - Can Bus Interfaces

The Speed Switch Relay de-activates front park sensors above a set speed. It gets around this problem by switching a 12 volt or 24 volt device on or off at a preset speed.

Been thinking about this. The power to the doors has to be on at all times because I have electric latching. So I would need a passive switch (no current draw). And I would have to have 2 (one for each door). And whatever device it is would have to be in the door. I would have to bypass this for the window motor.

This is looking like one of those things that I don't really need to do (the kind of stuff that I do that keeps me from finishing this car)!
