Rocket as­sis­tance to save mo­tor cy­clists

Motor Equipment News - - NEWS -

Mo­tor­cy­cling is great fun, and of­ten the fastest way to travel – but prob­lems arise when weather changes or the road gets slip­pery, and two wheels don’t give the grip of four.

So Bosch has come up with an in­no­vat­ing way to “lift” a bike that’s start­ing to lose trac­tion – by ap­ply­ing “rocket” power.

Of­ten a mo­tor­cy­clist will be able to right the bike by ap­ply­ing power, but it needs a lot of skill and road room to do so. An ad­di­tional lat­eral force, how­ever, could do the trick, and this is the idea be­hind the slid­ing mit­i­ga­tion Bosch is de­vel­op­ing in a re­search project. Like a magic hand, it keeps the mo­tor­cy­cle on track and con­sid­er­ably re­duces the risk of a fall.

A sen­sor de­tects side­ways wheel slip. If a cer­tain value is ex­ceeded, gas is re­leased from a gas ac­cu­mu­la­tor of the type used in pas­sen­ger-car airbags. The gas flows into the tank adapter and is vented in a cer­tain di­rec­tion through a noz­zle; this re­verse thrust keeps the mo­tor­cy­cle on track.

Yes, there are a few ques­tions to be an­swered, such as how much gas is needed and where there’s space on a bike, as well as recharg­ing, etc., but the fact it, is DOES work – Bosch has built a work­ing pro­to­type.

Bosch is also work­ing on other sys­tems. One is to give mo­tor­cy­cles radar as a sen­sory or­gan to en­ables new mo­tor­cy­cle as­sis­tance and safety func­tions while pro­vid­ing an ac­cu­rate pic­ture of the ve­hi­cle’s sur­round­ings. As a re­sult, these as­sis­tance func­tions not only in­crease safety, they also en­hance en­joy­ment and con­ve­nience by mak­ing life eas­ier for rid­ers.

One such func­tion is adap­tive cruise con­trol (ACC), as found in many cars to­day. Rid­ing in heavy traf­fic and main­tain­ing the cor­rect dis­tance to the ve­hi­cle in front takes a great deal of con­cen­tra­tion and is stren­u­ous over longer pe­ri­ods. ACC ad­justs the ve­hi­cle speed to the flow of traf­fic and main­tains the nec­es­sary safe fol­low­ing dis­tance.

This can ef­fec­tively pre­vent rearend col­li­sions caused by in­suf­fi­cient dis­tance to the ve­hi­cle in front. And not only does ACC of­fer rid­ers more con­ve­nience, it also al­lows them to con­cen­trate more on the road, par­tic­u­larly in high-den­sity traf­fic.

An­other is for­ward col­li­sion warn­ing sys­tem. In road traf­fic, even the briefest lapse in con­cen­tra­tion can have se­ri­ous con­se­quences. Bosch has de­vel­oped a col­li­sion warn­ing sys­tem for mo­tor­cy­cles to re­duce the risk of a rear-end col­li­sion or to mit­i­gate its con­se­quences. The sys­tem is ac­tive as soon as the ve­hi­cle starts and it sup­ports the rider in all rel­e­vant speed ranges.

If the sys­tem de­tects that an­other ve­hi­cle is dan­ger­ously close and the rider does not re­act to the sit­u­a­tion, it warns the rider by way of an acous­tic or op­ti­cal sig­nal.

Then there’s blind-spot de­tec­tion. This sys­tem keeps a look­out in all di­rec­tions to help mo­tor­cy­clists change lanes safely. A radar sen­sor serves as the blind-spot recog­ni­tion sys­tem’s elec­tronic eye, reg­is­ter­ing ob­jects in hard-to-see ar­eas. When­ever there is a ve­hi­cle in the rider’s blind spot, the tech­nol­ogy warns them by way of an op­ti­cal sig­nal – for ex­am­ple, in the rear-view mir­ror.

And, of course, there’s ABS. Since 1984, Bosch has been con­tin­u­ously per­fect­ing mo­tor­cy­cle ABS tech­nol­ogy in order to make this im­por­tant safety tech­nol­ogy avail­able for all ve­hi­cle classes in ev­ery mar­ket.

Ac­cord­ing to Bosch ac­ci­dent re­search, roughly one in four mo­tor­cy­cle ac­ci­dents in­volv­ing fa­tal­i­ties and in­juries could be pre­vented if all two-wheel­ers were fit­ted with ABS. World­wide, more and more coun­tries and re­gions, in­clud­ing the EU, Ja­pan, Tai­wan, and Brazil, are man­dat­ing mo­tor­cy­cle ABS.

Since April this year mo­tor­cy­cle ABS has been manda­tory in In­dia for all new two-wheeler types with an en­gine dis­place­ment above 125cc. ABS 10 was de­signed specif­i­cally to meet the re­quire­ments for mo­torised twowheel­ers in emerg­ing mar­kets.

Mo­tor­cy­cle sta­bil­ity con­trol is the world’s first all-in-one safety sys­tem for two-wheel­ers. By mon­i­tor­ing two-wheeler pa­ram­e­ters such as lean an­gle, the sys­tem can in­stan­ta­neously ad­just its elec­tronic brak­ing and ac­cel­er­a­tion in­ter­ven­tions to suit the cur­rent rid­ing sta­tus. In this way, the Bosch sys­tem can pre­vent the bike from low sid­ing or right­ing it­self sud­denly and un­con­trol­lably when brak­ing in bends, which is where the ma­jor­ity of mo­tor­cy­cle ac­ci­dents oc­cur. The new 6D sen­sor in the MSC sys­tem is the small­est and light­est de­sign on the mar­ket. It sig­nif­i­cantly im­proves mount­ing flex­i­bil­ity, and is less prone to vi­bra­tion.

Mo­tor­cy­cle-to-car com­mu­ni­ca­tion is an­other im­por­tant func­tion. By en­abling mo­tor­cy­cles and cars to com­mu­ni­cate with each other, Bosch is cre­at­ing a dig­i­tal shield for mo­tor­cy­clists. Up to 10 times a sec­ond, ve­hi­cles within a ra­dius of sev­eral hun­dred me­ters ex­change in­for­ma­tion about ve­hi­cle type, speed, po­si­tion, and di­rec­tion of travel.

Long be­fore a mo­tor­cy­cle comes into view, this tech­nol­ogy warns driv­ers and the sen­sors in their ve­hi­cles that a mo­tor­cy­cle is ap­proach­ing. This al­lows them to drive bet­ter and more de­fen­sively.

Side thrusters can help “lift” a bike if its low sid­ing be­cause of ice, gravel, or wet leaves on the road.

Con­nec­tiv­ity. These two are go­ing to meet – but if they’re con­nected it doesn’t have to re­sult in a crash!
