The invention provides an adaptive cruise method and device, equipment and a medium. The method comprises the following steps of acquiring an expected driving track of a vehicle in real time; determining an ACC virtual channel based on the expected driving track; determining a target vehicle on the ACC virtual channel as a vehicle following object to perform vehicle following; wherein the width value of the ACC virtual channel is increased along the driving direction of the vehicle. An ACC virtual channel in self-adaptive cruise is widened, and the farther the ACC virtual channel is in the driving direction, the larger the width value of the ACC virtual channel is, so that a target close to a predicted track of a vehicle at a long distance is easier to select, and the vehicle responds to the target earlier; situations of missing selection and too late braking of the target can be avoided to a great extent, the remote target recognition capability is improved, and driving safety is improved.
本发明提供一种自适应巡航方法及装置、设备及介质,该方法包括实时获取自车的预期行驶轨迹;基于所述预期行驶轨迹确定ACC虚拟通道;确定所述ACC虚拟通道上的目标车辆作为跟车对象进行跟车;其中,所述ACC虚拟通道的宽度值沿自车的行驶方向增大。通过将自适应巡航中的ACC虚拟通道进行拓宽,沿着驾驶方向,越远的位置ACC虚拟通道的宽度值越大,从而使得远距离处、与自车预测轨迹相近的目标将更容易被选取,自车将更早地对该目标进行响应,可以很大程度上避免对目标的漏选和制动过晚的情况,提升了远距离目标识别的能力,提高驾驶的安全性。
