摘要
针对车辆通过典型路面时悬架控制系统的延迟问题,通过系统建模和机器视觉的方法研究了一种采用完全预瞄的悬架控制系统。该系统首先基于OpenCV对前方典型路面进行检测,通过对典型路面特征的识别、跟踪和测距完成预瞄操作,并融合车辆实时信息对悬架进行理想化控制。通过试验结果表明,基于视觉处理的预瞄方法可以准确检测典型路面的特征信息,采用预瞄后的悬架控制系统可以使悬架发挥更优的减振性能。在特定情况下解决了悬架控制系统的响应时间延迟问题。
A suspension control system using preview is studied by means of system modeling and machine vision for the delay problem of the suspension control system when the vehicle passes the typical road surface.The system firstly detected the typical road surface in front based on OpenCV,through the recognition,tracking and ranging of typical pavement features,and integrated the real-time vehicle information to ideally control the suspension.The test results show that the visual processing-based preview method can accurately detect the characteristic information of typical road surface.The suspension control system after preview can make the suspension exert better vibration absorption performance.The response time delay problem of suspension control system is solved under certain circumstances.
