The invention discloses a self-adaptive PID automobile driving cruise control method. The method comprises the following steps of: 1, defining a vector class; 2, acquiring information of surrounding vehicles; 3, avoiding collision; and 4, controlling the acceleration and deceleration of the vehicle through a PID algorithm. Compared with a driver, the algorithm has shorter response time, can respond faster for the change of the speed of the front vehicle, and reduces the change of the speed of the vehicle as much as possible, so that the traffic is more stable. Software is used for simulating and testing the algorithm, and the result shows that acceleration and deceleration of the vehicle are well controlled due to addition of the PID algorithm in the self-adaptive PID vehicle driving cruise control method, and the speed of the vehicle can reach an expected target faster due to a feedback mechanism of the PID algorithm.

    本发明公开了一种自适应PID的汽车行驶巡航控制方法,包括如下步骤:步骤一,定义向量类;步骤二,获取周围车辆的信息;步骤三,避免碰撞;步骤四,通过PID算法来控制车辆的加速、减速。相比驾驶员来说,这一算法具有更短的反应时间,对于前方车辆速度的改变,也能反应更快,并且尽量减少本车车速的改变,使交通更加稳定。本发明使用软件来模拟测试这一算法,结果表明,本发明所述的自适应PID的汽车行驶巡航控制方法中PID算法的加入使车辆的加速和减速得到了很好的控制,它的反馈机制能够使车辆的速度更快的达到预期目标。
