摘要 为了合理制定轮毂电机直驱赛车的行驶策略,缩短完赛时间,提出了基于改进BB-BC算法的策略优化方法。在分析传统BB-BC算法不足的基础上,通过引入混沌逻辑映射的方法,形成改进的BB-BC算法。利用Matlab/Simulink建立了轮毂电机直驱赛车整车优化模型并进行了实车验证,进一步对行驶策略进行优化研究。结果表明,改进的BB-BC算法不仅收敛速度快,而且可有效避免算法陷入局部最优解,优化后的行驶策略缩短了完赛时间,为后续实时策略的制定提供了基础。 In order to formulate the driving strategy for in-wheel-motor racing cars and to shorten the completion time of the race,an optimization method based on the improved BB-BC algorithm was proposed.The traditional BB-BC algorithm was analyzed and the improved BB-BC algorithm was formed by integrating the chaotic logic mapping.A model of the in-wheel-motor racing car was established by using Matlab/Simulink and the experiment on real car was carried out for driving strategy optimization.The results show that the improved BB-BC algorithm not only has a fast convergence speed,but also can effectively avoid falling into the local optimal solution.The optimized strategy shortens the completion time and provides a basis for the subsequent real-time strategy formulation.
