Anybody know if AP is smart enough to use regen braking or does it just apply the actual brakes anytime it needs to slow down? Curious to see if my driving with manual regen is more efficient than AP driving.
Yep, it uses regen when slowing and balancing stopping power. Depending on wether the stoping speed senses enough regen capacity is available to stop within its (rather over sensitive) stopping/slowing distance, it will mix in calipers as needed. It will use slightly more physical breaking than the human with more experience with regen.
2019.36.x improved this to allow for more balance towards regen than pads for AP I believe.
