The invention relates to a decision-making method and device for an automatic driving vehicle, and belongs to the technical field of automatic driving. Driving scene information and current vehicle operation information are acquired in real time, scene feature information is extracted, decision model matching is performed from a scene feature-decision model database by using the scene feature information, and decision models corresponding to various scenes are stored in the scene feature-decision model database. And when the decision model is successfully matched and the decision strategy of the decision model contains danger alarm information, comparing the current decision strategy with the decision strategy in the successfully matched decision model, and selecting the strategy with the highest vehicle safety to control the vehicle. According to the method, a safer decision-making strategy can be quickly made under the condition that the vehicle encounters danger, and the safety performance of the automatic driving vehicle is improved.
本发明涉及一种自动驾驶车辆的决策方法及装置,属于自动驾驶技术领域。本发明实时获取行驶场景信息及当前车辆运行信息,提取场景特征信息,利用场景特征信息从场景特征‑决策模型数据库内进行决策模型匹配,所述场景特征‑决策模型数据库中存储有与各类场景对应的决策模型,当有决策模型匹配成功且该决策模型的决策策略中包含有危险报警信息时,则比较当前决策策略与匹配成功的决策模型中的决策策略,选择车辆安全性最高的策略控制车辆。该方法能够在车辆遇到危险的情况下,迅速做出更为安全的决策策略,提高了自动驾驶车辆的安全性能。
