The invention relates to a vehicle following time interval control method and device of a vehicle cruise system, a vehicle and a medium, and the method comprises the steps that when the cruise system is in an activated state, whether a target following vehicle meeting a preset speed condition exists in front of the vehicle or not is detected; if a target following vehicle meeting the preset speed condition exists in front of the vehicle, under the condition that at least one set of following vehicles meeting the preset reference condition exist, the target vehicle following time interval of the vehicle is calculated, the longitudinal vehicle speed of the vehicle is adjusted according to the target vehicle following time interval, and otherwise, the longitudinal vehicle speed of the vehicle is adjusted. And adjusting the longitudinal vehicle speed of the vehicle based on the current vehicle speed of the target following vehicle and the preset vehicle following time interval so as to drive along with the target following vehicle. Therefore, the technical problems that in the related technology, the vehicle following time interval is a fixed value, does not conform to the driving habit and expectation of a driver, and is difficult to meet the safety requirement in a special scene, so that the use scene of a cruise system is limited, and the function applicability is low are solved.

    本申请涉及一种车辆巡航系统的跟车时距控制方法、装置、车辆及介质,其中,方法包括:在巡航系统处于激活状态下,检测车辆的前方是否存在满足预设速度条件的目标跟随车辆;如果车辆的前方存在满足预设速度条件的目标跟随车辆,则在存在满足预设参照条件的至少一组跟随车辆的情况下,计算车辆的目标跟车时距,并根据目标跟车时距调整车辆的纵向车速,否则,基于目标跟随车辆的当前车速和预设跟车时距调整车辆的纵向车速,以随着目标跟随车辆行驶。由此,解决了相关技术中,跟车时距为固定值,不符合驾驶员的驾驶习惯和预期,难以满足特殊场景下的安全性要求,导致巡航系统的使用场景受限,功能的适用性较低的技术问题。
