【摘要】 从实用的角度提出影响AMT轿车换挡品质的评价指标,并以这些指标和换挡时的主观评价等级构成的样本向量训练并测试神经网络。利用Matlab/Simulink搭建AMT整车模型和换挡品质客观评价模型,通过仿真验证整车控制算法和评价指标提取算法的正确性,为AMT开发前期的性能提供预测。换挡品质评价实验表明开发的评价体系不仅可以实现换挡品质的客观评价,而且对AMT车辆参数标定也起到参考和指导的作用。更多还原

【Abstract】 The evaluation indices which affected shift quality of AMT-Cars are proposed from a practical point of view in this paper.The Neural Network(NN) is trained and tested with sample vectors comprised by the evaluation indices and subjective evaluation rates.A vehicle simulation model and an objective evaluation model of AMT are designed in Matlab/Simulink.The correctness of the vehicle control algorithms and algorithms extracted evaluation index are validated by simulation,and the per-development performance of AMT is predicted successfully.The experimental results show that the evaluation system cannot only be used to realize the objective evaluation of shift quality,but also be used as a reference and guidance role for the calibration vehicles equipped with automated manual transmission.更多还原
