基于ABS的ESP液压控制系统的设计

Design on the hydraulics loop of ESP based on ABS

设计了带ESP的ABS液压控制系统回路,并对液压控制系统的工作过程进行了详细的分析。ESP从提高汽车行驶稳定性的控制目标出发,通过调节作用在车轮上纵向力的大小,在车体上产生一个横摆力偶矩,从而纠正汽车的行驶姿态,改善汽车的转向特性,使汽车在各种行驶工况下都获得良好的行驶稳定性。

In this paper, the ABS vehicle hydraulics control loop with ESP is designed, the working process is analyzed in detail. ESP sets out from the control objective of raising the stability of autombile, and a yaw moment of couple is produced by adjusting the congitudinal force on wheel. Then the running gesture is corrected, the steering characteristic is improved, which makes the automobile more steady in all travelling situations.
