A few more tidbits learned this week. We know that 1cb:d2,d3 is Target Braking and 1cb:d0,d1 is Regen Braking. The latter, however, is the target regen braking - that is, it is what regen would be applied if it wasn't limited by other factors (such as being in neutral, at 100% charge,no regen bubbles,etc). It appears that 1d5:d0,d1 is actual regen braking. When I change my braking monitor to use this value instead, the braking monitor correctly reflects the true regen response to applied pedal. Furthermore, this value very closely track motor amps * 1.3 (when the motor is generating power) - which takes me to the second tidbit. The target and actual regen signals do not include regen during coasting(foot off both pedals, but not in neutral). If you let off the accel, we all know regen is engaged. This regen is not reflected in these messages. However, if I instead use motor_amps(1d4:d2,d3)*1.4, that signal almost perfectly tracks applied regen when the brake pedal is used but also responds to regen during coasting. I have updated CANary to use this instead so the brake monitor reflects the true braking force from regen. Need to test a little more but will publish soon.
