Regenerative Braking Setting

[wmras]

Yep, same. Really wish I could set it standard. I can set it in the individual drive profile, but the car always starts in normal, right?

Our 2020 TS locks the Auto Regen in the Individual mode. We get all our favorites by turning to Individual immediately.

Coasting on the highway & recup in traffic. I rarely use the Auto Recup but I should give it a try

Yes, you should. it is a hoot! Tried it this week during a Porsche club 125-mile route. It slows down to track the car in front of you when they slow down for curves. Gets a little too close to avoid stone chips, but definitely puts the car in a race mode.

Auto regen is also easy on the passenger's stomach, unlike one-pedal driving, it gracefully moves from throttle to coast to braking.

There were a couple of threads previously about brake lights and recoup/regen. This is one of them

Without muddying the waters (and I admit I haven't read all the posts in this thread!) I use the auto regen after reading somewhere (Porsche magazine?) that coasting is most efficient and the auto setting coasts wherever possible and uses regen as necessary.

Where we are in this current thread is that we've established that there are international regulations that require brake lights to be activated at and above a specified rate of deceleration, regardless of use of brake pedal or recup.
That rate is a surprisingly (to me at least) low 1.5 to 2 mph per second (converting from the regulated 0.7 to 1.3 m/s^2- the reason for the range of values is the lights may come on at the lower end of the range and must come on by the upper end).
But we don't (I think) yet have confirmed evidence that our Taycans comply. We could do with a forum convoy to test it out ?

I appreciate the potted recap Mr Wuff Trips.
*I have no further meaningful evidence to add to this thread your honour.

*Although I could ask one of my staffers to look into it next time I am chairing a UN summit.

curious to know if anyone drives with regen braking on all the time…or are there more appropriate times to turn it on vs other situations…thanks

I have to turn mine on every time i start the car. If i select Auto in the PCM it doesn’t seem to make a difference? I would like to keep it on all the time as it helps with range.

Funnily, the second post of that thread says: "There is another thread here about that." ?
(You did say "one of them"; still funny.)

Most of the time is auto on my car.

There is no way as far as I know (someone correct me if I'm wrong, of course). I believe for the same reason that the car is back on NORMAL with practically every driving-related setting back to default when you start: So that a person driving the car from parked, which may or may not be the person who has driven it last, can expect the same behavior from the car without surprises.

What I, and lots of others, have done, is activate Regen or Auto Regen in INDIVIDUAL, and flip the sports chrono wheel to INDIVIDUAL after starting.

I’ve only had mine a few months I tend to hit the button only when I want the car to slow down on its own. If you use the adaptive cruise control it will turn it off. Not sure that you really get much juice from doing it on the plus side it kind of feels like downshifting.

I always drive with mine on the highest mode A it gives you a extra safety warning when you are to close to a car and auto slows the car just a little, see no reason not to be as safe as you can.

Optimum for range is the standard coast setting it defaults to in "Normal" mode.

I believe some government regulation specifies that the car has to start in the mode used to certify the car - not sure which country but it seems that is why all Taycans start in Normal mode.

Conveniently (for me) Normal is the most efficient mode that is comfortable, since range lowers and stiffens the suspension, so it suits me to start and stay in Normal almost all the time.

I can't believe I've read through this thread 3 times now and still don't understand how this works. I didn't understand the concept way back when I first entertained the thought of this car (or any EV) either, try as my husband did to explain it. Now I've driven about 500 miles (that's what the car says, but it feels like so much less!) and every time I get in I try a different brake setting in a different scenario and still don't know what the &*#^! is going on half the time. I experienced the slow down at a traffic light the first time yesterday, but maybe that was an assistance thing I left on.

I drove this super cool TSD Rally last weekend and didn't touch the regen because I was focusing entirely on testing different Innodrive and Limiter settings (and learned how to reset the trip odometer, oops). So basically, this car has Always on, Sorta Always on, and REALLY Always on? I'm just hoping it'll click eventually with more experience driving. I just love this car so freaking much I want to understand every itty bitty thing about it and give it all the attention and proper use it deserves.

Since I'm lazy, instead of wasting the diamond button on sport sound and having to press and hold the recuperation button (I like auto recuperation btw), I just assigned all that stuff to individual mode.

Much easier to just turn the knob on startup then pressing multiple buttons.

My individual mode is based on normal so it retains the auto lowering features that normal mode has.

My brake regeneration kicked in at exactly 600 km. It makes you relearn the braking as it feels very different from when you only rely on mechanical braking.

Do you, like, not drive the car? You've had it for a while now, and 500 miles is more like "running out for groceries". (Why do you hate your Taycan?) ?

Lemme try:
- (preamble) The car has 2 mechanisms for slowing down - hydraulic brakes (friction pad on disc), and "motor" braking (regenerative), whereby the electric motors "resist" the spinning/rotation of the axles, and convert that into electric energy. Sometimes these 2 mechanisms work together, in other cases they are actuated individually.
- brake pedal braking: this is just you, and only you, no settings/knobs/controls. (Kinda, getting there.) This mode of braking combines the 2 mechanisms, according largely to the following algorithm:

* below ~600mi, pedal braking is only friction/hydraulic; (the remainder applies after this point​

* upon starting the car, the first 3-4 actuations (might depend on time or distance spent braking) of the pedal produce hydraulic braking only​

* in general, at speeds over 6-7mph, pedal braking is regenerative braking - and much stronger. This is indicated by the green arc in the center dial. Continuing to brake below 6mph transitions to hydraulic braking, sometimes with a noticeable reduction in pedal feel and/or rate of deceleration. (Watch out for this in stop-n-go traffic.)​

- recuperation: this is another way of slowing down the car. It's actuated from a button on the left arm of the steering wheel, and has 3 stages: off (default), on (first/short press), auto (long press)

* in off mode, lifting off the electron pedal means the car will coast (it actually feeds just a tiny bit of current to the motors). Slowing down requires explicit braking.​

* in on mode, lifting off means the regenerative braking is triggered to a small, fixed amount: the car recoups some of the energy, insufficient for stopping except on an incline at slow speed. This is more of an "ICE/engine braking" feeling, useful to modulate speed in moving traffic.​

* in auto mode, lifting off means the car uses its cameras to figure what's the optimal response: if no obstacles are detected, it will coast (like in the off mode); otherwise it will increase the rate of deceleration as needed - beyond the 'on' mode but not sufficiently to stop safely. This is useful in high speed traffic that may encounter a rare slowdown (say, around exits/merging points).​

InnoDrive/assisted driving will obviously override the above. There's also the 'basic assist' which may slam on the (hydraulic) brakes if the car detects what it perceives to be an imminent collision.

(Homework: add 500 miles by EoW.)

Edit: my hand-crafted indentation of bullet points is crap.
