摘　　要：在分析传统的汽车制动力检测数据拟合方法存在不足的基础上,提出了采用三次B样条函数拟合与优化的新方法,并对该方法进行了深入的理论分析。试验结果和应用情况表明:该方法很好地解决了汽车性能检测中难以解决的制动力检测数据的分析与处理问题,使其检测精度、数据重复性乃至整个检测系统的稳定性与可靠性都大为提高。最后,对该方法的软件实现技术作了简单介绍。By giving an analysis to weak points existing in traditional auto braking testing data quasiharmony method, authors set forth the new method of application of cubic B spline quasiharmony and optimization. A thorough analysis of the method is made in theory. The experimental result and actual practice show that the method has made available a better way for the solution to braking data analysis and treatment which is challenging in auto function test. And in this way, the testing accuracy, data repetition and the whole reliability and steadiness of the testing system can be greatly improved. The software designing technique for this method is also introduced in the paper.
