This blog documents the restoration, and conversion, of a 1965 Humber (Singer) Vogue to a fully electric vehicle. The Vogue will be powered by an 11kW(modified), 3 phase industrial AC motor, controlled by an industry standard Variable Speed Drive (VSD) or Inverter. To be able to produce the 400 volts phase to phase the VSD will need about 600 VDC of batteries. A big thanks to the contributors on the AEVA forum:

Accelerator Pedal Mounting

Some time ago I completely ripped out the original accelerator system in the Vogue with the intention of replacing it with a modern "fly-by-wire" pedal. That hasn't been as easy as I thought it would be. I have been fussing with ideas for a week or so. I actually have two pedals, one from an Audi A4 and one from a VW Polo. I bought the Polo one after the Audi one because it seemed a bit more compact.

This is the Polo pedal. This is most likely the one I will use. (Later edit: I didn't - I used the Audi one - modified a little.)
And this is the Audi pedal. The rod is too long and the pedal is biased about 100mm to the right of where it mounts.

One of the problems is that the Vogue has two metal panels in the front mudguard area - inner and outer. The red circle is where I have to add an extra bolt but it will not be accessible in the wheel area on the other side. (Very old picture shown here.)
More as it evolves...

I've been following this build for a while now and am interested to see how you interface the pedal to the VFD. What sort of signal to they give you to work with?

Hi Vincent
These 2 pedals have two potentiometers in them. One gives 0.7 to 4.7V and the other 0.35 to 2.35 V - from a 5V supply - they track. I'll just use the one output for 0.7 to 4.7 V. The VFD can do anything I like with the signal - offset, amplify etc.
