Facts prove ESP electronic stability programs can effectively reduce the incidence of major traffic accident, thus saving a lot of peoples life, in order to further strengthen the safety car ride, global road experts agreed that ESP should become each a cars standard. Automobile Electronic stability device (Electronic Stablity, abbreviation ESP) - by A Benz company first used in its class A car. ESP is actually a traction control system, compared with other traction control system, ESP not only control the drive wheels, and can control the driven pulley. Such as rear wheel drive car too often appear of the steering wheel, now out of control and guy, ESP will brake to slow the outside of the car front wheel to stable; In turn, for correction followed had little tracing direction, ESP will brake slow, thus correction within rear wheel traveling direction. This paper introduces the automobile electronic stability system ESP work principle, components, function and its maintenance method. Keywords: electronic stability programs,；driving stability,；excessive steering,；understeer 目 录 引言 1 1.
