自主车辆计算资源的自适应优化以提高性能和能量

Adaptive Optimization of Autonomous Vehicle Computational Resources for Performance and Energy Improvement

Saurabh Jambotkar, Longxiang Guo, Yunyi Jia

摘要:

自动驾驶汽车通常会消耗大量的计算能力来进行操作,特别是使用人工智能算法进行传感和感知的任务。这样的计算不仅可能花费大量的能量,而且当机载计算资源有限时还可能导致性能问题。为了解决这个问题,本文提出了一种自适应优化方法,根据车辆所面临的情况的上下文,在多个车辆子系统之间在线分配自主车辆的车载计算资源。设计了不同的自动驾驶场景来验证所提出的方法,结果表明,与现有的计算安排相比,它可以帮助提高自动驾驶汽车的整体性能和能源消耗。

英文摘要:

Autonomous vehicles usually consume a large amount of computational power for their operations, especially for the tasks of sensing and perception with artificial intelligence algorithms. Such a computation may not only cost a significant amount of energy but also cause performance issues when the onboard computational resources are limited. To address this issue, this paper proposes an adaptive optimization method to online allocate the onboard computational resources of an autonomous vehicle amongst multiple vehicular subsystems depending on the contexts of the situations that the vehicle is facing. Different autonomous driving scenarios were designed to validate the proposed approach and the results showed that it could help improve the overall performance and energy consumption of autonomous vehicles compared to existing computational arrangement.
