Summary:

In order to obtain the information of vehicle response which was hard for the driver to perceive, an integrated driving-intention (IDI) method of analyzing and evaluation for powertrain objective drivability was proposed herein. First, the objective evaluation indexes of drivability were studied with the vehicle longitudinal dynamic theory, an intelligent drivability objective evaluation tools (I-DOET) was designed and the software and hardware platform were introduced. Besides, the vehicle acceleration signal was processed by combining power spectral density(PSD)，time-frequency diagram and low-pass filtering algorithm because of its nonlinearity and strong interference. What's more, driving cycle identification with multi-source signal fusion can be implemented based on data layer. Finally, the IDI was identified by multi-source signal fusion, and the feature quantity of objective drivability was extracted according to steady state response ability, transient performance, ride comfort and synchronization. The results show that this IDI analyzing and evaluating method and test analysis platform of powertrain have good reliability and accuracy.In addition, this research can not only be used for the objective evaluation of drivability, but also provides a reference method for the objective evaluation of vehicle comfort and handling stability
