New BMW i3s traction control system for all future BMW and MINI models.

Munich. The BMW i3 sets standards worldwide for
driving pleasure in a purely electrically-driven vehicle. Key factors
here are not only the increased output of the motor in the new BMW
i3s, but also the innovative traction control system adapted
specifically to the instantaneous power deliver of the BMW eDrive
system. Presented for the first time in the new BMW i3s (270 Nm at 0
rpm, 135 kW / 184 HP, power consumption combined in European NEFZ
test-cycle*: 14.3 kWh/100 km; CO2 emissions combined: 0 g/km), the
system improves traction and driving stability in adverse weather and
road conditions when pulling away, in active Brake Energy Regeneration
phases and when accelerating out of tight corners. At the heart of
this innovation is the control system’s 50-times-faster routine, made
possible because – unlike conventional driving stability systems – the
control process is now calculated directly in the powertrain instead
of in a remote unit requiring long signal paths. This development
provides further evidence of BMW i as a pioneer of innovative
technology within the BMW Group.

“With their high levels of torque and instantaneous responses to
every movement of the accelerator, electric motors already make
significantly higher demands on driving stability systems than
conventional power units,” explains Peter Langen, Head of Chassis
Development at BMW.

That’s why the BMW engineers developed a new type of system
geared squarely to the demands of electric mobility.
The
positive impact of these shorter control cycles is not reserved for
purely electrically driven cars; indeed, this innovative traction
control system also optimises traction, driving stability and driving
dynamics in vehicles with combustion engines. It will therefore be
fitted in BMW and MINI models with front-, rear- and all-wheel drive
to deliver noticeably greater assurance and driving pleasure when road
conditions make pulling away difficult.
