The embodiment of the invention relates to the technical field of intelligent traffic, in particular to a preference-based anthropomorphic automatic driving model design method and system, and the method comprises the following steps: converting the information of an automatic driving vehicle into an aerial view through employing an aerial view perception method, and obtaining the state information of the environment around the automatic driving vehicle; a deep reinforcement learning method based on preference selection is adopted, the aerial view is mapped to continuous actions of a bottom layer, and a driver model is generated; setting different action preferences to represent driving styles of different drivers, and training the driver model based on the different driving styles to generate a plurality of alternative actions; and selecting an alternative action which is close to the set action preference as a final action, and obtaining a preference-based personification driver model. The technical problem that an existing automatic driving model deviates to be homogenized and cannot provide different preferred driving styles is solved.

    本申请实施例涉及智能交通技术领域,特别涉及一种基于偏好的拟人化自动驾驶模型设计方法及系统,该方法包括以下步骤:采用鸟瞰图感知方法,将自动驾驶车辆信息转化为鸟瞰图,并得到自动驾驶车辆周围的环境状态信息;采用基于偏好选择的深度强化学习方法,将鸟瞰图映射到底层的连续动作,生成驾驶员模型;设定不同的动作偏好来表示不同驾驶员的驾驶风格,并基于不同的驾驶风格,对驾驶员模型进行训练,生成多个备选动作;选择与设定的动作偏好接近的备选动作作为最终动作,得到基于偏好的拟人化驾驶员模型。本申请解决现有的自动驾驶模型偏向于同质化,无法提供不同偏好驾驶风格的技术问题。
