The invention is suitable for the technical field of vehicle automatic driving, and provides an environment sensing method for an automatic driving vehicle, and the method comprises the following steps: presetting a road database which comprises driving lane width standard data and emergency lane width standard data; obtaining road surface image data of a road where the vehicle is located and generating left-side distance data and right-side distance data, wherein the left-side distance data and the right-side distance data are distances between the vehicle and the guardrails on the two sides; comparing the left-side spacing data with the right-side spacing data according to a preset road database to obtain a comparison result; and generating a vehicle driving instruction according to the comparison result, so that the vehicle continuously drives according to the road width standard in a specified path under the condition that the road indication line does not exist. Auxiliary cooperation is carried out under the specific condition that road marking lines are not clear according to the existing automatic driving technology, so that the automatic driving applicability is wider.

    本发明适用于车辆自动驾驶技术领域,提供了一种自动驾驶车辆的环境感知方法,所述方法包括以下步骤:预设道路数据库,所述道路数据库包括行驶车道宽度标准数据和应急车道宽度标准数据;获取车辆所处道路的路面图像数据并生成左侧间距数据和右侧间距数据,所述左侧间距数据和右侧间距数据为车辆距离两侧护栏的间距;根据预设道路数据库对左侧间距数据和右侧间距数据进行比对得到比对结果;根据比对结果生成车辆行驶指令,使得车辆在没有道路指示线的情况下按照道路宽度标准以规定路径持续行驶。针对现有自动驾驶技术在道路标示线不清晰的具体情况下进行辅助配合,使得自动驾驶适用性更广泛。
