[Ovmsdev] Twizy45 testing needed

[Michael Balzer]

Hi Julien,

thanks :-)

Great to read everything works as designed :-)

Supplementing the POWER command, you should also try

RAMPS 100 100
+
SMOOTH 0

-- this sets start and acceleration ramps to maximum speed and disables 
smoothing. This makes the Twizy much more responsive to the throttle and 
can make more difference than the 11% torque increase (120% will be cut 
down internally to 111%).

For RECUP, take a look at docs/Twizy-Torque-Speed-Profiles.ods: you can 
shape the braking recuperation strength per speed. Try:

TSMAP B 80 100 60 40

-- this is from sheet 2 "Recup1" and will shift the braking recup max to 
~39 kph. This works pretty well on the T80 with 40% braking recup level.
Btw: the TSMAP speed points are at the same for the T45.

Regards,
Michael

> 42 on brake is scary: you’re already at 27, once you barely touch the brake, 42% recuperation kicks in after half a second, so you get your expected friction-brake slowdown and boom, an extra slow down from recuperation… 42 is really too agressive, making an in between/modulated foot controlled slowdown nearly impossible…
