The embodiment of the invention provides a self-adaptive cruise control method and system based on self-vehicle calibration and fuzzy control. The longitudinal characteristics of a local vehicle are calibrated by using a least square identification mode; a driving mode close to an actual driver is achieved by means of a fuzzy PID control method; and therefore, the longitudinal control performance can be improved, the comfort and the fuel economy can be improved, the burden of the driver is relieved, traffic accidents are reduced or avoided, unnecessary vehicle speed changes are reduced, fuel can be saved to the maximum extent, exhaust pollution can be reduced, and the power performance and the riding comfort of the vehicle are improved.

    本发明实施例提供一种基于自车标定和模糊控制的自适应巡航控制方法和系统,利用最小二乘辨识的方式标定出自车的纵向特性,结合模糊PID的控制方法,达到接近实际驾驶人的开车方式,既能提高纵向控制性能,又能提高舒适性和燃油经济性;减轻了驾驶员的负担,从而减少或避免了交通事故的发生,减少了不必要的车速变化,可以最大限度地节省燃料,降低排气污染,提高汽车的动力性能和乘坐的舒适性。
