The new BMW i3s, unveiled in August last year, features an innovative traction control system that is adapted specifically to the instantaneous power delivery of the eDrive system. The system will make its way to all the future BMW and Mini models, the company said.
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, BMW said.
“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, the company added.
