摘要:

提出了一种基于深度强化学习的多目标自主制动系统。该系统的设计是在一个连续的行动空间中制定的,旨在最大限度地提高行人的安全性和感知以及乘客的舒适度。车辆代理的训练对一个大型的自然数据集,其中包含行人过马路的试验,受访者在各种交通条件下,在一个互动的虚拟现实环境中走过一条道路。采用近端策略优化和深度确定性策略梯度两种强化学习方法,通过计算机模拟学习制动控制策略,并比较了两种方法的效率。结果表明,该系统能够在保持安全制动的同时,将对乘客舒适性的负面影响降低一半。

英文摘要:

A deep reinforcement learning based multi-objective autonomous braking system is presented. The design of the system is formulated in a continuous action space and seeks to maximize both pedestrian safety and perception as well as passenger comfort. The vehicle agent is trained against a large naturalistic dataset containing pedestrian road-crossing trials in which respondents walked across a road under various traffic conditions within an interactive virtual reality environment. The policy for brake control is learned through computer simulation using two reinforcement learning methods i.e. Proximal Policy Optimization and Deep Deterministic Policy Gradient and the efficiency of each are compared. Results show that the system is able to reduce the negative influence on passenger comfort by half while maintaining safe braking operation.
