I think you've lost sight of the initial concern that was raised. There's still a common-mode failure of loss of control power.
Control power is different from actuation power, the latter of which is what you're addressing. And it's not "gross damage" because it's a common-mode failure, so you can't just ignore it like that.
- extrapickles 4y agoTo lose local regen braking derived power requires a failure of the cars systems similar in nature to one that would cause loss of hydraulic fluid or air in a traditional braking system. Edit: made more concise.
- linkdink 4y agoI see what you're saying now
- londons_explore 4y agoIt is trivial to derive control power from actuation power - at least enough for a few can-busses that run from each wheel to up-to-12 independent sensors on the brake pedal.
- linkdink 4y agoIt's trivial if you're doing an opportunistic design, but it's challenging to match the safety and reliability of a hydraulic system while beating the cost.
