| 摘 要： | 介绍了自行研制的汽车巡航控制系统，其主要由控制及调整开产、传感器、控制单元和执行机构组成；采用变参数ＰＩ控制算法，根据系统判别的汽车行驶状况（节气门开度和车速）和目标车速与实际车速之间的偏差大小来调整控制参数。该系统可以在汽车行驶过程中实现车速的自动控制，具有车速保持、微调以及恢复功能，有助于减轻驾驶员的疲劳程度，提高驾驶舒适性。

| Abstract: | The paper presents a self developed automobile digital cruising control system which may reduce degree of fatigue and offer good comfort to driver in the course of driving because of its automatic speed control ability and speed maintaining, microadjusting and recovering functions. Main constituent of the system includes: control and adjustment switch, sensor, control unit and executive mechanism. The PI control algorithm is utilized with variable parameter which is adjusted by the automobile driving condition (throttling valve opening and driving speed) and size of difference between objective speed and practical speed judged by the system. |
