The invention relates to the field of intelligent driving, and discloses a self-adaptive cruise control method and device, a vehicle and a storage medium. The method comprises the steps that the speed of a front vehicle and the speed of a vehicle at the current moment are obtained, and the relative speed between the two vehicles is calculated according to the speed of the front vehicle and the speed of the vehicle; respectively calculating a real-time headway and a target headway corresponding to the current moment based on the relative speed; and comparing the real-time headway with the target headway, and correspondingly controlling the real-time speed of the vehicle according to a comparison result. According to the embodiment of the invention, the relative speed is introduced to predict the speed change condition of the preceding vehicle, so that the real-time vehicle speed is controlled, the anti-interference capability of self-adaptive cruise control is improved, the dynamic performance of real-time vehicle head time interval control is effectively improved, and the driving safety and the vehicle following performance in a complex environment are ensured.

    本申请涉及智能驾驶领域,公开了一种自适应巡航控制方法、装置、车辆和存储介质。该方法包括:获取当前时刻下的前车车速和本车车速,并根据前车车速和本车车速计算两车之间的相对速度;基于相对速度,分别计算当前时刻对应的实时车头时距和目标车头时距;将实时车头时距与目标车头时距进行比较,根据比较结果来相应控制本车的实时车速。本申请实施例通过引入相对速度来预测前车的速度变化情况,进而实现对实时车速的控制,提高自适应巡航控制的抗干扰能力,有效改善实时车头时距控制的动态性能,保证复杂环境下的行车安全性和跟车性。
