摘要
针对通用全液压转向系统工作过程中存在的方向盘归零偏差,开发一种新型电比例主动控制液压转向系统。在对其原理分析的基础上,进行了电比例主动控制液压转向系统的硬件设计,并提出了相应的软件控制算法。以叉车为实验平台,通过实验验证所设计系统的有效性。实验结果表明,本系统明显改善了工程车辆的转向性能,提高了转向精度。
In order to eliminate the zero adjustment error exiting in ordinary full-hydraulic steering system, we de- velop a new type of electro-proportional active control steering system. The hardware and software algorithm designs are accomplished respectively on the foundation of principle analysis. Besides, we conduct the experimental test based on forklift truck, which proves that the electro-proportional active control steering system could imProve the vehicle＇ s steering performance effectively, as well as steering precision.
