Intuitively I thought that that SHOULD be the case but wasn't 100% sure. Now, form engineering standpoint, how is this accomplished, are the brakes "fly by wire" so to speak and the car engages them after max regen is reached and when you ask for more braking, or the brake system is basically the same as any other car with direct mechanics (pedal) to hydraulics action and regen is a stand-by function and even a slight touch of the pedal does lead to SOME mechanical braking + give a computer OK for more regen? Any Nissan engineers here that could confirm or disprove or correct my assumptions?garygid wrote:Generally you ask for some braking "force" with the brake pedal.
When Regen is activated by the car itself, it is pure Regen, limited
to what the car requests, what it could produce, and what it is
allowed to produce.
With braking requests from team brake pedal, the car usually/often
first generates a very little braking force mechanically, by getting the
brake pads to just barely touch the discs, so that they will be
"instantly" ready to supply a lot more braking force, mechanically.
Owever, the car tries to provide as much of the braking force as it can
with Regen, only applying more mechanical braking force when needed.

Once you cross a certain threshold that friction is applied, regen is backed off even if it was already being applied.
I love my chirp mod on my SOC meter. I doesn't chirp much anymore now that I am trained but occasionally I start to slide and it's there to remind me.
They are conventional mechanical-hydraulic brakes like you find in most power brake setups, except the boost is provided by an electrical servo in place of a vacuum booster. Regen is "fly-by-wire"BestPal wrote: "fly by wire"
I guess the definition of "fly by wire" could be argued, but this thread says brakes are fly by wire, with mechanical fail safe.Herm wrote:They are conventional mechanical-hydraulic brakes like you find in most power brake setups, except the boost is provided by an electrical servo in place of a vacuum booster.

At this time no easy way to determine exactly when mechanical brakes kick in.BestPal wrote:Sorry if this had been discussed and cleared before, the search didn't return anything. I want to understand optimal regen performance under normal braking. Is it safe to assume that brakes only engage after max regeneration has been reached (all circles on regen meter)? In other words, if i'm coasting to a stop in eco mode and seeing 2 circles on regen meter, if I slightly touch the brakes will the Leaf increase regen to 3 then then to 4 circles (max it out) before applying mechanical brakes or does the brake pedal automatically actuate hydraulics and more regen is just added on top of that?
