CA, APR. 26 ~ In an afte rnoon meeting on voluntary standards between officials of th e Specialty Vehicle Institu te of Am erica (SVIA ) ATV manufa cturers representat ives, and Consumer Product Safet y Commi ssion (CP SC) staff, a co ns u lting en g ineer pron ounced that " it is hard to find criteria" in esta blish ing test procedures to det ermin e th e sta bi lity o f three-wh eeled ATVs. Dr. Dav id Weir , Tech n ica l Director o f Dyn amic Research , In c., a so u thern Californiabased en gi neeri ng consultin g firm which ha s done vehicle studies for th e depart me nts o f T ra ns porta tio n (DOT) and Defen se (DO D), mad e this conclusion after presenting possible test ing procedures a n d criteria to m ea sure ATV stability a n d hand lin~ cha rac teristics. V. eir's presentation was m ad e a t the request of the C PSC, which plans to use some fo rm o f AT V h andlin g testing as part of th e vol untar y ATV sa fety sta n da rd that the federal agency is working o n with th e ATV ind ustry. Bu t, if C PS C s ta ff m ember s thought th at th ere wa s a cl ear-cut, esta blished method of determining th e ride -wo rt hi ness of ATVs, Weir's dissertation reveal ed otherwise. Even though there is already esta blish ed testing background wh ich can be ap p lie d to ATVs from both a u to mobiles an d motorcycles, Weir exp la ined that three-wheelers possess handling tra its wh ich a re unique to their design a nd where they o pera te, th us req u iring new testi ng criteria and proc;edures. The possible outlook is tha t i t may take many months, at least a year, before an ATV handling test staridard is developed; even then , it may not be what the CPSC is envisioning, nor may it produce the results th ey want. -At the top o f Weir's presentation, h e said that " th e technology exists to crea te testing procedures for ATVs, bu t th ere a re limits for what ca n be done in esta blish ing th em ." Weii1isted th e type s o f ta sks (ma n eu vers) whi ch would be used in esta blishing a cri teria fo r ATV handl in g testing. In cluded are turn s ("steady sta te", "s top steers"), sla lo m co urse, accelera tion. u phills a nd downh ill s. Weir a dded th at traversin g crossslopes (going across th e face o f a hi ll or sand d u ne ) is a task almost un ique to ATVs. Other u ni q ue ta sks woul d or cou ld include "disturban ce" (a com bina tio n o f a ll ta sks), " ride" (o perator co m fort ), "driveabili ty" (how th e ATV fun ct ions rel ative to engine pe rforma nce), a nd " u tility" (how th e AT V can ca rry .. load), " O nce eac h of thes e task s are understood," not ed Weir , "com bin ing tasks ca n be discu ssed. " Weir sta ted th at of th e h anding characteristics wh ich au tomobiles and mo to rcycles have, " ATVs are so me w here in between." H e sai d th a t au to s rely on steerin g a ng le for turn s. vehi cle ro ll is described as a " n u isance" trai t, a n d driver posi tio n ing is irre levan t. Other factors incl ud e sig nificant lateral (sideways) acceleratio n , a nd m inima l "cou p ling" between lat e ra l a nd lon g itud in al (le ngthwise) dynamics (the way th e car m oves as it travel s). Mot orcycl es dep end o n steeri ng to rque for tu rn s; roll ing (ba n king in turns) is necessary, the ride r must work in th e bi ke's p la ne of symmetry (or stay in- line wi th bike), and there is negl igible la teral accelera tio n. Weir states that motorcycles have "significant" lateral and longitudi na l coup li ng. T hree-wheeled ATVs, Weir expla in ed , incl ude some handl in g ch ar acteristics fro m both . Steering angle is rel ied upon mos tly a t low speeds; stee ri ng torq ue m ostly a t h igh er speeds. T h ree -w hee lers are n o t banked -turn vehicles; so ro ll is a nuisance. Rider movem ent is a sign ifica nt in p ut o n th e vehi cle . There is so me lat eral acce lera tio n, a nd th ere is so me la teral a nd longitudin a l co upling , especia lly wh en used with the brakes a nd th rottle. Weir sta ted that factors to co ns ide r in ATV hand ling testing would in : c1 ude: veh icle co n fig u ra tio n , initial speed, and co ntrol inpu t. Facto rs un ique to ATVs in th e tes t would be ride r size a nd weigh t, soi l properties, and terr a in contour. Wei r said th a t da ta th at co u ld be recorded from a typical th ree-wh eeler handl in g test wo u ld incl ude ride r inpu ts, vehicle a tti tu de , vehi cle velocity an d acce ler- ari on, pa th measures (such as how well it stays travelling in a stra igh t . lin e; sto p pi n g distance), and subjec• rive rider ratings a nd co m mentary. Add itiona lly, to a ll o f th e a bo ve, Weir noted th at conducting such tasks to record data wo u ld be " more com o. plicated in a n off-road envi ro n ment." This, he later explained, is due ma inl y to rider input an d differences in terrain a nd so il mak eup, all of which h ave " p ro fo u nd effects" o n th e dyna m ics o f ATV handling. Weir mentioned that even though there have been severa l stud ies made over the yea rs on soil and tire traction, all ha ve yielded inconclusive results. " Yo u will have to determine (the vehicle's ) good and bad limits and what to include, to determine yo ur testing criter ia ," said Weir. "And that' s tough to determin e. You can draw u pon past automobile and motorcycle testin g procedures to apply to ATV s, but it's hard to find th e criteri a (for testing) . . . it's a complicated problem." When asked by CPSC ATV Task Force Cha irman Nick Marchica where to start deve loping an ATV safet y sta ndar d, Weir replied , " Yo u shou ld get a better understanding of the veh icle and how it behaves." "T he industry is interested in meetin g th e testing tim e sched u le," said H onda 's Ed Gl ynn . "Can it be ac hieved?" " Yes," rep lied Weir, addi ng "it's a ma tte r o f what can be don e, but no ha rd n u mber ca n be ac hieved overn igh t." After Weir's p resentation, th e su bjec ts o f age-labeling, traini ng co urses and co ntrol sta ndards were di scu ssed . T he SVIA will draft a sta ndard for three-wheeled ATV dynamic stabi lity, and th e CPSC will dr aft a " discussio n paper" o n age label in g . Both documents a re expected to be ready for the nex t voluntary sta ndards meeting, wh ich will be h eld at CP SC staff headquarters in Bethesda , Maryl and. Also on th e age nda will be furth er d iscu ssion o n train in g a nd eq u ipment a nd co ntrols. T he next ATV ind us try-C PSC voluntary sta ndards m eeting is ten tatiyely sched u led for May 22-23. • , CPSC sets public hearings . WASHINGTON, D.C., APR. 30 The U .S.
