基于混合体系结构的无人驾驶车辆系统

摘要

从无人驾驶车辆系统的自主性、实时性、适应性要求出发,建立了基于功能和行为相结合的无人驾驶车辆混合式体系结构,基于功能的分解结构满足无人驾驶车辆的自主控制要求,基于行为的分解结构则满足由于行车环境复杂性以及多变性带来的对无人驾驶车辆车系统局部路径规划要求的反应能力和适应能力.实验结果表明,基于混合式体系结构的无人驾驶车辆系统具有自主性,且在环境发生变化时满足实时性及适应性要求.%Hybrid architecture of autonomous vehicle system was built based both on function and behavior so that requirements in autonomy, real-time and adaptability could be met. Functional decomposition architecture was used to automatically control the vehicle while behavioral decomposition architecture was used to handle the complexity and variability of environment which highly challenged responsiveness and adaptability of vehicle' s planning system. Experimental results showed that a hybrid architecture based system enabled the vehicle to drive autonomously while having sufficient adaptability and real-time as the environment changes.
