The invention discloses a background traffic flow model construction method and system based on automatic driving, and relates to the technical field of automatic driving testing. The method comprises the following steps: acquiring driving data of a test vehicle and a lane changing vehicle; based on the viscoelastic-plastic constitutive relationship, respectively calculating the stress relationship of the test vehicle in the lane changing process, wherein the stress relationship comprises driver self-driving force, vehicle interaction force and lane force; and establishing a motion trend model of the vehicle according to the stress relationship. The method is based on mechanics and is combined with the viscoelastic-plastic constitutive relation, and the displacement, the speed and the acceleration of the vehicle can be accurately represented through simulation verification of a public data set, so that the accuracy of characteristic parameter extraction in the testing process is ensured.

    本发明公开了一种基于自动驾驶的背景交通流模型构建方法及系统,涉及自动驾驶测试技术领域。本发明包括以下步骤:获取测试车辆和换道车辆的行驶数据;基于粘弹塑性本构关系分别计算测试车辆在换道过程中的受力关系,受力关系包括驾驶员自驱力、车辆交互力和车道力;根据受力关系建立车辆的运动趋势模型。本发明以力学为基础,与粘弹塑性本构关系相结合,通过对公开数据集的模拟验证,该方法能够准确地表示车辆的位移、速度和加速度,从而确保了在测试过程中特征参数抽取的准确性。
