摘要 随着生活水平的不断提高，人们对于汽车的操控性和告适性有了更商的要求。这其中， 车辆碱振系统起着至关重要的作用，而采用被动直架很难仇到了两全其美，于是，适应能力更 强，感受更完美的电控悬加系统就证生了。随着电子技术的迅帮发展，车用微机、各种传感 器执行元件的可靠性和寿命都大幅度提高了,为满足人们对汽车舒适性的要求，20 世纪 90 年代以来，各大汽车公司相继研发了提高汽车合适性的电控悬架系统 ECS 【Electronic control suspension)。在汽车上装备了电控晤架系统，当汽车急转索、急加速或紧急制动时 车上人员能够感觉到悬间较为坚硬， 而在正常行驶时能够感觉到县架比较柔软。电控县架还 能平衡地面反力,使其对车身的影响减小到最低程度。 因此, 随着汽车电子技术的快速发展， 许多中高档轿车、大客车以及越野汽车上都装备了电控悬架系统- 关负词，电控县扣 ”检修“注意事项  Abstract With the continuous improvement ofliving standards, peoplefor the control of the car and comfort have higher requirements. Among these the vehicle vibration reduction system plays a very important role, and the passive suspension is very difficult to satisfy both sides, therefore, stronger abiity to adapt to feel more perfect electronic control suspension system was born With the rapid development of electronic technology, computer sensors perform vehicle reliability and service life of components is greatly improved,to meet the requirements on car comfort, since the nineteen ninties, each big car companies have developed to improve the comfort of automobile electronic control suspension system ECS (Electronic control suspension)，Equipped with electronic control suspension system on the vehicle when the vehicle tums, rapid acceleration or braking, the personnel on the car can feel suspension are more rigid, while in normal driving can feel softer suspension, Electronic control suspension can balance the ground reaction force, makes its effects on the body reduced to the lowest degree. Therefore
