Beijing Institute of Technology)【Abstract】The calculation of driving wheel slip ratio by using rear wheel speed as reference speed could lead to a calculation error and wrong intervention of acceleration slip regulation (ASR) when vehicle was turning at low speed, therefore a modified algorithm was introduced for calculating driving wheel slip ratio under cornering situation. In the algorithm, the yaw rate and the steering wheel angle of vehicle are firstly estimated by two driven wheels without corresponding sensors, then the front wheel reference speed was obtained, and driving wheel slip ratio was amended with front wheel reference speed replacing vehicle speed finally. Experimental results showed that the calculation error of slip ratio was eliminated, and wrong intervention when the vehicle is accelerating on highadhesion road surface disappeared after the modification.

A new type electroniccontrolled pneumatic adjustable shock absorber which adopts solenoid valve and swing pneumatic cylinder as driving mechanism is designed, and damping characteristic of the shock absorber is analyzed by putation and analysis. Specimen of the adjustable shock absorber was developed and was subjected to damping performance bench test. It is shown that the average deviation of the damping force test values from simulation is less than 7%, except for the pression resistance of the rear shock absorber, proving validity of the simulation model. Road rid test with the adjustable damping shock absorber fitted on board indicates that rid fort of bus equipped with the damping adjustable shock absorber is better than the one with passive shock absorber.Key words: Air suspension。設(shè)計(jì)了以電磁閥和擺動(dòng)氣缸作為驅(qū)動(dòng)機(jī)構(gòu)的電控氣動(dòng)式可調(diào)阻尼減振器，通過(guò)仿真計(jì)算分析了該減振器的阻尼特性。試驗(yàn)結(jié)果表明,采用本文提出的起步質(zhì)量控制策略與控制算法，、。 Windows CE基于環(huán)模型的輪胎有限元建模與仿真研究邱恩超1 郭孔輝2（ 汽車(chē)安全與節(jié)能?chē)?guó)家重點(diǎn)實(shí)驗(yàn)室； 汽車(chē)動(dòng)態(tài)模擬國(guó)
