Abstract

Currently, with the advancement of dual-clutch transmission (DCT) control systems and vehicle performance, it is necessary to develop better objective evaluation methods for DCT vehicles. The starting process is a critical element affecting the driving and riding experience of DCT vehicles. Therefore, it is crucial to establish and improve a starting process evaluation model for the objective evaluation to DCT vehicles and optimization to DCT control strategies. This paper proposes a new method to evaluate the DCT vehicle starting process objectively. The method analyzes and models the time-series signals of the driving data using the LSTM neural network and uses the attention mechanism to improve the evaluation performance and enhance the interpretability of the evaluation results. Taking the dynamic performance evaluation as an example, the evaluation results indicate that the proposed model is better than the conventional methods, showing notable efficacy and preponderance.

基于注意力机制的 LSTM 神经网络的 DCT 车辆启动过程评估研究
目前,随着双离合变速器(DCT)控制系统和车辆性能的发展,有必要为双离合变速器车辆开发更好的客观评价方法。起步过程是影响 DCT 车辆驾驶和乘坐体验的关键因素。因此,建立和改进起步过程评价模型对于客观评价 DCT 车辆和优化 DCT 控制策略至关重要。本文提出了一种客观评价 DCT 车辆起步过程的新方法。该方法利用 LSTM 神经网络对驾驶数据的时间序列信号进行分析和建模,并利用注意力机制提高评价性能,增强评价结果的可解释性。以动态性能评估为例,评估结果表明所提出的模型优于传统方法,显示出显著的有效性和优越性。
