论文摘要
本文提出了一种自动停车的新方法。由于其便利性,自主停车场引起了很多关注,但是由于环境复杂和车辆的非自主限制,很难在短时间内获得无碰撞和可行的道路。为了解决这个问题,本文介绍了一种新型算法,称为多效力杂种A*(MHHA*),该算法结合了多螺旋a* and Hybrid a*的特征。因此,它可以提供保证,以避免局部最小值和次级临时性,并在短时间内产生可行的路径。本文还提出了一种基于坐标转换的新碰撞检查方法,该方法可以提高计算效率。在模拟实验中,将所提出的方法的性能与杂化A*进行了比较,并且已经证明了其优越性。
This paper proposed a novel method for autonomous parking. Autonomous parking has received a lot of attention because of its convenience, but due to the complex environment and the non-holonomic constraints of vehicle, it is difficult to get a collision-free and feasible path in a short time. To solve this problem, this paper introduced a novel algorithm called Multi-Heuristic Hybrid A* (MHHA*) which incorporates the characteristic of Multi-Heuristic A* and Hybrid A*. So it could provide the guarantee for completeness, the avoidance of local minimum and sub-optimality, and generate a feasible path in a short time. And this paper also proposed a new collision check method based on coordinate transformation which could improve the computational efficiency. The performance of the proposed method was compared with Hybrid A* in simulation experiments and its superiority has been proved.
