Turning angle disabeling regen?

[thomas.rueesch]

Hi Together
Just wanted to confirm if this is a normal behaviour of the Roadster:
When turning at a very tight corner (tight hairpin curve) where you go to a max turning point the regen turns off...as soon you go straighter again everythings back to normal.

Is this a normal thing?

many thanks

The regen turns off when some rear wheel slippage occurs. So if you are going around a sharp corner fast while braking, the inside wheel might start to lock up and activate the ABS and disable regen. If you are not braking, I dont think the regen will turn off unless you hit some loose surface. How fast are you going?

Hi, thanks for your reply and thanks for your confirmation
that this is a intentional behaviour you have to be aware of, when driving downhill (that you do no get surprised in a negative way...going from oversteering to understeering in a split second due to the sudden drop of regenarative breaking.
But I have also experienced this in a parking garage (spiral down)...and I did't have the feeling that there was any slipage (but a very narrow turning circle).

I did't have the feeling that there was any slipage (but a very narrow turning circle).

My understanding is that the Roadster detects slippage by observing a speed differential between the 2 rear wheels. It isn't hard to believe that the differential speed during a tight turn could exceed the same threshold as slippage.
I haven't noticed it but certainly can believe it.
