    A path-planning algorithm for autonomous vehicles based on traffic stability criteria: the AS-IAPF algorithm by M. Zhao, M. Zhao, X. Li, Y. Lu, H. Wang, S. Ning

    Published 2024-11-01
    “…Secondly, based on the aforementioned threshold discriminant formula, a new AS-IAPF algorithm is proposed. The algorithm mainly includes two aspects: firstly, by pre-generating initial paths and introducing a Gaussian oscillation coefficient of force fields, it avoids the algorithm falling into local optima; secondly, by using the aforementioned driving stability threshold discriminant formula as a dimensional adjustment for adaptively improving and adjusting the strength coefficient of the AS-APF repulsive field, the algorithm further improves the efficiency of path planning. …”
