The invention discloses a vehicle lane changing safety detection method and device, a vehicle and a storage medium, and the method comprises the steps: detecting a driving intention of a user; when it is detected that the driving intention is a lane changing intention, generating a minimum safe distance from a vehicle to a front vehicle by using a pre-trained kinematics model, and generating an expected safe distance of a target lane by using a pre-trained car-following model; and comparing the minimum safety distance and the expected safety distance with the corresponding actual distance, and giving a vehicle lane changing warning when the minimum safety distance or the expected safety distance is smaller than the corresponding actual distance. Therefore, the technical problems that in the related technology, lane changing freedom and lane changing assisting models are calculated through a kinematic model containing weight coefficients, parameter setting is complex, engineering application implementation is not facilitated, and only insufficient safety of rear vehicles is considered are solved.
本申请公开了一种车辆变道的安全检测方法、装置、车辆及存储介质,其中,方法包括:检测用户的驾驶意图;在检测到驾驶意图为变道意图时,利用预先训练的运动学模型生成本车距离前车的最小安全距离,并利用预先训练的跟驰模型生成目标车道的期望安全距离;对比最小安全距离和期望安全距离与对应的实际距离,并在最小安全距离或期望安全距离小于对应的实际距离时进行车辆变道警示。由此,解决了相关技术中通过含有权重系数的运动学模型计算变道自由、协助变道模型,参数整定复杂,不利于工程应用实现,且仅考虑后方车辆安全性不足的技术问题。
