The invention discloses an early warning method, an early warning device, a vehicle and a nonvolatile computer readable storage medium. The early warning method comprises the steps of collecting a scene image in front of a current vehicle; detecting the position of a vehicle in the scene image based on a preset target detection model, and calculating the relative distance between the current vehicles according to the position; the fatigue state of a driving object of the current vehicle is obtained, and the braking distance is determined according to the fatigue state; and early warning the current vehicle according to the relative distance and the braking distance. According to the early warning method, the early warning device, the vehicle and the non-volatile computer readable storage medium, due to the fact that the fatigue state of the driving object of the current vehicle is considered, the early warning grade of the current vehicle can be graded more accurately, and driving safety is guaranteed. In addition, a device for distance measurement does not need to be installed in the current vehicle, so that the manufacturing cost of the vehicle is reduced.
本申请公开一种预警方法、预警装置、车及非易失性计算机可读存储介质。预警方法包括采集当前车辆前方的场景图像;基于预设的目标检测模型检测场景图像中车辆的位置,并根据位置计算当前车辆与车辆的相对距离;获取当前车辆的驾驶对象的疲劳状态,并根据疲劳状态确定制动距离;及根据相对距离和制动距离对当前车辆预警。本申请实施方式的预警方法、预警装置、车及非易失性计算机可读存储介质中,由于考虑到当前车辆的驾驶对象的疲劳状态,从而能够更准确的对当前车辆预警等级进行分级,以保证行车安全。此外,免去了在当前车辆中安装用于测距的装置,以降低车的制造成本。
