Post All Future BMW to Get i3S Traction Control System That's 50x Faster

BIMMERPOST
     Featured on BIMMERPOST.com
The new system is 50 times quicker.

Press Release:

January 3, 2018

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.

On blizzard days like today (North East Coast), there are hundreds of ENTHUSIASTS that wish the traction/stability control system was 50x faster.
Some even complain that their BMW's aren't as good in the snow as they thought (mostly because of poor tire choices), but a quicker system would definitely help across the board.

The "OFF" button is always there.

Hopefully the system will be programmed to also STOP intervening 50x faster. The main thing that annoys me with current BMW traction control programming is that it will continue to hold back your power way, way after you no longer need it do. Because the system can react so quickly, they would not need to be so conservative with the way they set it up.

I like it. Very smart for them to do this.

As for those who don't want it and think they are a great driver I'm sure the off button will be provided. We'll see you guys who think you are awesome drivers on the side of the road, up a curb or smashed into a tree. Most people are not quite as good as they think they are.

Actually... not new... unless you are driving an E30, E28, or E24 or previous... but a 50% better nanny...

now if the electronic steering algorithm will only get 50% better... we might get our whole Bimmer back!

I thought the "off" button was just the DSC completely off, no? We already have a way to turn off all traction assist by holding the DSC button for 2 seconds.

I agree 100%. Most people don't know how annoying and condescending they are either!

If we are talking about an electronic system and not a mechanical one, how would the signal path length make any significant difference in the system speed?

It may be that it can now run at a higher sample rate / control loop rate because there was a bottleneck somewhere before.

This will be tremendous if it works anything like Tesla's traction control. You always get maximum acceleration without wheelspin in a Tesla. No power cut, no blinking lights, no burning rubber. It would greatly help the M2/M3/M4 in normal mode.

Maybe BMW should spend less money on bloviation and more on proofreading:
