The invention relates to a front vehicle track long-time prediction method and device, electronic equipment and a storage medium, and the method comprises the steps: detecting the actual working condition of a current vehicle, and obtaining a plurality of vehicle driving parameter relational expressions of the current vehicle when the actual working condition is detected to be a following working condition; based on the multiple vehicle driving parameter relational expressions, a vehicle following mathematical model of the current vehicle is obtained, the vehicle following mathematical model and a preset intelligent driver model are fused, and an initial basic vehicle following model of the current vehicle is generated; and calibrating the initial basic car-following model to obtain a final basic car-following model, and predicting a front vehicle track of the current vehicle based on the plurality of vehicle driving parameter relational expressions and the final basic car-following model. Therefore, the problems that a traditional IDM model has defects under some working conditions, and the requirement for long-time accurate prediction of the front vehicle track is difficult to meet are solved.

    本申请涉及一种前车轨迹的长时预测方法、装置、电子设备及存储介质,其中,方法包括:检测当前车辆的实际工况,并在检测到实际工况为跟车工况的情况下,获取当前车辆的多个车辆行驶参数关系式;基于多个车辆行驶参数关系式,获取当前车辆的跟车数学模型,并融合跟车数学模型和预设的智能驾驶员模型,生成当前车辆的初始基础跟驰模型;标定初始基础跟驰模型,得到最终的基础跟驰模型,并基于多个车辆行驶参数关系式和最终的基础跟驰模型,预测当前车辆的前车轨迹。由此,解决了传统的IDM模型在一些工况下存在缺陷,难以满足前车轨迹长时精准预测的需求等问题。
