When it debuted two months ago, the new BMW i3s brought to market an 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), 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.
The control system has a 50-times-faster routine, thanks to the control process being calculated directly in the powertrain instead of in a remote unit requiring long signal paths.
“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 optimizes 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.
