摘　　要：提出一种基于传统机械模型的自动变速器换档最优化方法。将自动变速器中的离合器压力和发动机的降扭量作为优化参数,优化的目标是确定最优的控制数据,改善自动变速器性能,提高乘坐舒适性和减少换档的时间。采用序列二次规划算法,求解非线性优化问题。结果表明在不同负荷情况下,优化参数有明显的改进。It presents an optimization of shifting process for automatic transmission based on traditional mechanical model. The clutch pressure in AT and the engine load-reduction are used as optimal data. The objective of the optimization is to determine optimal control parameters, to improve the performance of AT, to enhance passenger's comfort and to reduce shift duration. The nonlinear optimization problem is solved with a sequential quadratic programming algorithm. The results show a great improvement in terms of optimization criteria for different load cases.
