If you ’ve expend any time on the r­oad , you ’ve probably spotted a few bumper dagger that make claims of divine driving intercession . While the most common varieties translate , " God is my co - pilot , " you may also bump the laurels fall to Jesus , Shiva , Barack Obama andSuperman’snemesis Gen. Zod , just to name a few .

car manufacturer still have n’t found a manner to offer customer driving guidance from the gods , but they have made inroad with therobotcommunity . Various troupe now feature such options as " figure dominance " and " electronic stability mastery . " If you own aSaab , you could proudly tell your friends and phratry thatpositive military group frame controlis your conscientious objector - pilot .

­It ’s easy to take vehicle stableness for granted , but m­any factor , such as inclement atmospheric condition or other drivers , can wrestle control of the roulette wheel from your hands . One 2d you ’re driving along a winter route , then one bike passes over an icy patch . The next matter you know , you’rebrakingand turn the roulette wheel to keep from going into the ditch . Once you think about those factor , it ’s no wonder so many driver are bully on letting the creator of the universe drive shotgun . Where human drive ability ( or common gumption ) fails , many put their fate in the hand of something great than themselves .

Computerizedstability organisation such as positive military unit anatomy restraint pop the question standardized protection . T­hey wo n’t protect you from deranged hitchhikers or magically steer you clear of an out - of - control vehicle , but they can keep an optic on ­road conditions and fomite performance , as well as make small adjustments to ensure better stability . If you ’re going to need to apply the brake to one steering wheel , a stability organisation can apply just the right press before you accredit there ’s a problem . Moreover , as is mutual with the work of invisible supreme beings , you often wo n’t even agnise the dominance organization did anything at all .

So just what does electropositive force form control entail ? Get to have a go at it your co - pilot on the next page .

Chassis Control: Enhanced Stability and Performance

Electronic stability control did n’t crop up overnight . Like any come out technology , it has evolved steadily from earliest advances . To find a exonerated ascendant to positive force chassis controller , you do n’t have to bet back any further than the introduction ofanti - lock brake systems(ABS ) in the late 1970s .

The trouble was simple : No matter how skilled a driver you bump to be , add up to a stop on a slippery surface was hard . If your bike started to skid , it was hard to steer or stop the vehicle than it was under dry conditions . To allow safer braking , ABS designers connected hurrying detector , pumps and valves to a central electronic accountant . If the sensors find the rapid steering wheel deceleration that signaled a wheel locking , the controller secern the ticker and valve to take turns brake pressure . This measure insure the wheels would slow at the same rate as the vehicle by allow the maximal braking power possible , just inadequate of a lockup .

Essentially , ABS designers put the finer points of braking on a slippy route in the capable hand of a car . Given the success of anti - lock brakes , it was only a issue of time before locomotive engineer applied the technology elsewhere on vehicles . In more sophisticated example , the onboard computer determine what the driver intends , feel what the vehicle is actually doing and , largely through the app of precise braking , makes minor fitting to bring about the safest , most realistic interpretation of the machine driver ’s wish . In this sense , it ’s much like the way word processors and Web web browser mechanically counterbalance spelling . The computer sense what you intend to type , produce the necessary department of corrections and , voila , you never even realize how regularly you fumbler " conciliate . "

Saab ’s confirming force chassis restraint system uses much of this same technology to improve driving constancy and provide a better drive overall . The essential parts of the system are as travel along :

Cross rack drive(XWD ): Developed in alignment with Haldex of Sweden , Saab ’s all - wheel drive system distributes drive torque equally between the two axle and between the two rearward wheel . This mean that fomite stability controls have even more room to o.k. - tune the driving experience through subtle braking adjustment .

Bachelor of Arts / ESP sensors : Yes , anti - lock brakes are n’t just the forefather of modern chassis control ; they ’re a vital portion . On top of the live engineering , Saab uses itselectronic stableness programto measure such factors as traction andvehicle yaw(the vehicle ’s rotation around its fundamental point during a turn or lane variety ) . This system , managed by the fomite ’s centralcontrol module , allows ABS technology to not only protect against wheel locking , but also help steer the vehicle through braking when stability begins to falter .

Electronic limited slip differentials(eLSD ): Differentials were originally intend to translate the torque of a vehicle ’s driveshaft to the axles . Over prison term , they ’ve come to stabilize the fomite on curves and turn , as well as help with slippery road conditions . On Saab vehicle , the eLSD system can redistribute 40 pct of the torsion between the rearward driveshaft to whichever wheel has the most adhesive friction on tricky roads . For an in - depth look at this engineering , readWhat is an eLSD ?

Lower chassis : incontrovertible force chassis control also imply the positioning of the vehicle chassis itself , by situating it nigher to the route with stiffer fountain and moistener to minimize dead body movement and ensure tight manipulation . Self - level dampersin the back of the vehicle study to maintain a constant drive tiptop .

Together , these component part augment the driver ’s skills , providing safer handling in vehicle such as the Saab Turbo X. Explore the links on the next page to pick up even more about the many technology that make our morning drive possible .
