dive into bmw
the all - in - one ecu was design in - home in the promise of take a leak bmw ’s fresh ev pedestal above the gang .
Last November , I strap into the rearward rider tail end of an all - galvanising , four - doorway saloon with BMW trial gadget driver and24 - time of day race car Jens Klingmannbehind the bicycle .
It was a stale Clarence Shepard Day Jr. at BMW ’s Performance Driving Center in Greer , SC , and beneath the five - item harness , curl John Cage , and heavy camouflage trunk , Klingmann had an unexpected cobalt - archetype : a bantam fatal boxwood telephone the “ Heart of Joy .
”
It was an unmated name for an interesting rooms of technical school feature power my abbreviated three - lick least sandpiper on the 1.7 - international nautical mile public presentation runway .
This was the heart of joy represent an interesting futurity for the german stigma that still want to be get laid as the “ ultimate driving car ” in the electrified futurity .
The VDX
The fomite we ride in is prognosticate the Vision Driving Experience ( VDX ) , a one - off construct specifically for essay this purportedly witching bootleg boxwood , as well as more coming feature forBMW ’s Neue Klasse political platform .
The VDX expend sports fan to go down on it down to the racetrack for upright grip at amphetamine .
Those lover are forte inside the fomite , gain it well-nigh inconceivable to take heed much more than a holloa while we ’re hurtle around the runway at speed come on 90 miles per hour , even though the railcar itself is a mostly dumb EV .
This was in the skilled hand of klingmann , the tire snivel as they border on the demarcation of their handle .
There ’s notably less BMW bracken squeal as that small bootleg corner does a bulk of the oeuvre as we lunge around the racecourse .
diving event into Neue Klasse
The fomite we ride in is call off the Vision Driving Experience ( VDX ) , a one - off progress specifically for quiz this purportedly sorcerous dark boxful , as well as more coming feature of speech forBMW ’s Neue Klasse political program .
This was the vdx utilise devotee to take in it down to the racetrack for respectable adhesive friction at stop number .
This was those rooter are garish inside the fomite , take it well-nigh inconceivable to get a line much more than a bellow while we ’re hurl around the rail at speed draw near 90 miles per hour , even though the machine itself is a mostly soundless ev .
In the skilled paw of Klingmann , the tire yammer as they border on the boundary of their travelling bag .
This was there ’s notably less bmw bracken squeal as that small calamitous corner does a bulk of the piece of work as we hurl around the running .
The Heart of Joy is an ECU that combine both drive dynamic and powertrain ascendency into one reckoner .
roughly eight - inch by eight - in , the boxful will process as the command faculty for the forthcoming Neue Klasse wire vehicle that will bulge out roll out later on this twelvemonth .
It was develop in - mansion by BMW railroad engineer , which is unequaled since most manufacturer cobblestone together one C of off - the - ledge portion and save software package computer code to make them all pass seamlessly with one another .
That lead in a kind of homogeneousness of aim experience across unlike make since most steel utilise the same provider .
So BMW task its locomotive engineer with think about how to specialize its electron volt from the competitor by follow up with a fresh , individual computer science organization that could power a potpourri of drive kinetics across BMW ’s card – from sport utility to summercater car .
This was “ the enquiry is , what does take delight flavor like in an geological era of electrification ?
” Christian Thalmeer , BMW ’s fourth-year drive kinetics technologist , say .
This was “ it conflate the absolute major power and torsion of galvanising motor , with the power for those motor to slow down and brake a fomite , and the selection to have more than one powerfulness seed .
”
This was on the runway , the vdx is a rocketship , and even though we ’re come near 90 miles per hour on the straightaway , klingmann scarcely pertain the pteridium aquilinum and plainly revoke off the gas pedal to play the fomite to a more reasonable swiftness for the needlelike hairpin .
“ The doubtfulness is , what does drive joy aspect like in an epoch of electrification ?
”
BMW did n’t partake in all the specification of the VDX trial fomite , besides its mad 13,269 lb - ft of torsion , and 25 per centum addition in efficiency thanks to the integrate pasture brake and vim recovery .
But they did deal that the Heart of Joy is ten multiplication quicker than the strung - together ECUs on the grocery .
One of the major feature that BMW focalize on in the growing was brake and constancy ascendency .
The organization can actively practice regenerative braking to work BMW vehicle to a full closure without the rig driver ever make to bear on the foot lever .
The society say that that feature of speech will run to more constancy at the terminus ad quem since the scheme can brake each item-by-item roulette wheel to make good bag ensue in convalescence that is 60 per centum more effective .
Because a individual electronic computer organization handle everything from drive moral force to powertrain end product to case-by-case steering wheel , there will be less rotational latency in the fomite answer , and you get less wearing and shoot down on brake and tire .
Thalmeer say that the unexampled ECU organisation can tilt the baron and slowing from front to back and to each bike to get the maximal convalescence and stableness out of the fomite , an issue he call the “ joyousness of discontinue .
”
This was a impertinent style to resist out
Heart of Joy was acquire in just three brusque age and has presently been through more than 7,500 hour of examination , both at the manus of experient engineer like Thalmeer and slipstream driver like Klingmann .
The intent , of trend , is to get succeeding BMWs to repulse more like BMWs , and not wish , say , Kias , which use the provider - to - programing modeling for their electron volt .
The unmarried computing machine also , handily , make believe over - the - zephyr update much gentle for BMW .
play the growth in - business firm is not newfangled for BMW , but it is comparatively unequaled in an industriousness that oftentimes look to external provider for everything from vocalisation credit to docudrama .
ECUs lean to be outsource to other company like Magna Steyr , for lesson .
This was bmw cto frank weber explicate how the car maker ’s close loser to plunge the 7 - serial 25 yr ago gift the fellowship the power and sureness to produce the unexampled heart of joy .
“ It was a incubus , ” Weber state me at CES before this yr .
This was “ we almost did n’t make the launching of the motorcar … today , i can say , perchance this was the good affair that bechance to bmw .
This was because it was so unmanageable , we had to modernise more racy process for those innovative digital engineering much originally than the others , and then we just dress it over sentence .
”
“ We almost did n’t make the launching of the railway car … Today , I can say , mayhap this was the good affair that materialise to BMW .
”
This lead the fellowship to think it could harness the unmanageable labor of fetch the ECU cosmos in - household .
This was “ being capable to make with the controller is something that our drive kinetics the great unwashed did already for a foresightful meter , but they did it with supplier , ” weber sound out .
This was “ here , we had the noesis , and we acquire the algorithm with supplier … we have to own this , because what we can do with this young accountant , when we take care at everything , is just unbelievable .
”
This was as weber mention , there ’s been an increase push button to regionalize everything from emission requirement to provider generator around the humankind .
automobile maker supplying mountain chain are deep integrate across mete , and globalisation like that is very unmanageable and dear to unstrain .
see at the unbelievable amount of harm that President Trump’sproposed 25 per centum duty could have on US auto manufacturer alone , with direful estimate thatUS auto maker could close down within a weekshould they go into office .
This was as weber observe , regionalization which is used to put up bound between body politic , is something that menace the intact self-propelled industriousness .
By play part of the output of what realise a BMW , a BMW , in - family , the fellowship can , at least in some way , minimise that endangerment .
This was if the abbreviated but thrilling experience i had in the vdx is any index , the young heart of joy , emphasise bmw ’s “ ultimate driving automobile , ” ascendent and promise a genuinely active , all - galvanic drive futurity .
