As traffic to o ls o f the mo d ern izat io n and ab so lute nu mb er increase sharp ly,traffic accid ents are also increasin g.C ar accid ent has beco me severe glo b al so cial issues. Und o ub ted ly,ad vanced auto safety facilit ies are the d riv in g safety ind isp ensab le safe guard.

ABS tasseled fo r the car in var io us d riv in g co nd it io ns b rak in g perfo r mance and b rak e safety p articu lar ly imp o rtant,esp ecia lly is emergency b rak ing,can make fu ll use o f the peak b etween t ire and ro ad surface ad hesio n p ro p erties, imp ro ve p er fo rma nce and red uce auto mo b ile fight sid es lip b rak ing d istance,give fu ll p la y to the b rak ing perfo r mance, b ut a lso increase the auto mo b ile b rak ing p ro cess co ntro l. So as to red uce the p o ssib ilit y o f car accid ents.

No installat io n ABS car,if the d riv in g fo rce tramp le b rake p edal, wheel w ill rap id ly lo wer sp eed,and finally wheels stop turn ing,b ut bo d y because o f inertia rema ins fo rward slid ing.T h is p heno me no n was at the whee l and p aveme nt o ccur b etween larger "s lip", app ear this k ind o f sit uat io n, the c ar tires o f auto mo b ile lateral sp read s almo st d isap pear, so po o r fo rce will app ear the fo llo w in g p heno mena:
