The invention discloses an unmanned vehicle intelligent decision-making method based on motivation and risk assessment. The method comprises the following steps: firstly, surrounding environment conditions and motivation are analyzed when a vehicle needs to be subjected to state change in a high-speed environment; on the basis, the motivation for changing the driving state is extracted and servesas the core of behavior decision making, decision making is conducted only when the motivation is triggered, and the current driving state is still kept under other conditions. And meanwhile, an unmanned vehicle surrounding environment risk assessment model is established to dynamically verify the decision result, the decision rationality is judged, and the optimal decision target point is calculated. According to the method, excessive meaningless decisions of a decision-making system in the driving process of the driverless automobile can be avoided, the calculation efficiency is improved, and real-time, efficient and safe driving decisions of the driverless automobile in a dynamic uncertain environment are realized.

    本发明公开了一种基于动机与风险评估的无人驾驶车辆智能决策方法,首先对高速环境下车辆需要进行状态改变时的周围环境条件、动机进行分析。在此基础上,提取了改变驾驶状态的动机,并将其作为行为决策的核心,在有动机触发时才进行决策,而其他情况下仍保持当前行驶状态。同时,建立无人驾驶车辆周围环境风险评估模型对决策结果进行动态验证,判断决策合理性、计算决策最优目标点。本发明能避免无人驾驶汽车行驶过程中决策系统过多无意义决策,提升计算效率,实现在动态不确定环境下的无人驾驶汽车实时、高效、安全的驾驶决策。
