in the UK i believe brake lights should illuminate when deceleration >= 0.7 metres per second squared. About 0.07g. So 0.2g (in the video) should definitely be triggering it.
As much as I agree with that concept the problem will be cruising along. anything other than 0 Regen the car actually bounces from power to Regen to power quite a bit. It would drive people behind you crazy and be beyond annoying. Blinking when the car is not even altering speed by 1mph...I seriously can't believe hyundai/Kia decided that this was the best way for the brake lights to operate.
Yes, I understand that the regen rate varies depending on how fast the car is going even when keeping the regen level the same but who cares? Just have them activate anytime there's regen.
Use one of the accelerometers to sense an elevated slowing rate. Several systems have them....the car actually bounces from power to Regen to power quite a bit. ...
Right. Brain fart, since corrected.Alec is the guy that hosts technology connections FYI
The issue is very much there, but I'm curious if the SA533 bulletin that came out at the start of April changed the behavior somewhat so, time to test
Watching the video now....
Great argument for Regen1, which I find very similar to automatic transmissions. Slows a little if I lift in a curve, but still needs the brake pedal to stop.

I've noticed that adaptive cruise, according to my brake light monitor LED, illuminate the brake lights far more than necessary on hilly terrain. If I'm on a downhill (not a steep mountain downhill, just a middling downhill that one frequently encounters on the deep interstate) when regen is simply preventing the car from gaining speed.As much as I agree with that concept the problem will be cruising along. anything other than 0 Regen the car actually bounces from power to Regen to power quite a bit.

They don't even need to do that. Thanks to the high gear ratio on the motor, they can already discern very minute changes in speed by monitoring motor speed. It's pretty simple math to calculate and monitor acceleration and deceleration rates. All they need to do is program it.Use one of the accelerometers to sense an elevated slowing rate.

Thanks for locating the exact regulation.FMVSS 108
Not sure I'd agree. Schedule 12 of the UK Road Vehicle Lighting Regulations is not really very clear either and basically surmounts to when the brake pedal is pushed and not much more.Europe has much clearer regulations. They are written the same way I would write a requirement in my job.
I don’t always agree with them, but they are clear and unambiguous
Thanks, was getting lost in stradalex ...For EU it’s
Regulation No 13 of the Economic Commission for Europe of the United Nations (UN/ECE) that covers braking
So in our case these somewhat might cancel each other out since the 'propulsion system' can continue to operate.18.104.22.168. All stop lamps shall be switched ON simultaneously when the braking system provides the relevant signal
defined in UN Regulations Nos. 13 and 13-H.
22.214.171.124. The stop lamps need not function if the device, which starts and/or stops the propulsion system, is in a
position that makes it impossible for the propulsion system to operate.
Does anyone know if the Canadian transport regulations allow this to happen as well? I know there are differences between Canadian and US regulations, eg the theft defeat issue. I have been trying to find it on the government website but my search 'Kung Fu' is not what it used to be.
