The invention provides a vehicle adaptive cruise control method and system, a computer and a readable storage medium, and the method comprises the steps: collecting the actual distance between a current vehicle and a front vehicle, and obtaining the actual speed of the current vehicle and the initial cruise speed set by a user; calculating an expected distance corresponding to the current vehicle based on a preset algorithm, and calculating a first difference value between the expected distance and the actual distance and a second difference value between the actual speed and the initial cruising speed; the first difference value is input into a first preset PID controller, the second difference value is input into a second preset PID controller, and the target acceleration or target deceleration of the current vehicle is calculated through the first preset PID controller and the second preset PID controller; and adjusting the initial cruise speed of the current vehicle according to the target acceleration or the target deceleration. By means of the mode, the phenomenon that the distance between the car and the car is too large or the car collides with the front car can be avoided, and then potential safety hazards are eliminated.

    本发明提供了一种车辆自适应巡航控制方法、系统、计算机及可读存储介质,该方法包括:采集到的当前车辆与前方车辆之间的实际距离,并获取当前车辆的实际速度以及用户设定的初始巡航速度;基于预设算法计算出当前车辆对应的预期距离,并计算出预期距离与实际距离之间的第一差值、实际速度与初始巡航速度之间的第二差值;将第一差值输入第一预设PID控制器中,并将第二差值输入第二预设PID控制器中,以通过第一预设PID控制器和第二预设PID控制器计算出当前车辆的目标加速度或者目标减速度;根据目标加速度或者目标减速度调整当前车辆的初始巡航速度。通过上述方式能够避免跟车间距过大或者与前车发生碰撞的现象发生,进而消除了安全隐患。
