The vehicle acceleration performance, the accelerator pedal controllability etc. have influence on the engine sound evaluation besides the sound level and quality. Subjective evaluation of the engine sound by the design of experiments was conducted with a driving simulator. As a result, the effects of the vehicle performance and the accelerator pedal controllability for the engine sound evaluation were measured quantitatively. It became clear that these factors could improve both “quiet feeling” and “sporty feeling” which show the evaluation of engine sound. 相似文献

Torque control of engine clutch to improve the driving quality of hybrid electric vehicles 总被引:1,自引:0,他引:1

As a powertrain for hybrid electric vehicles (HEVs), the automatic transmission (AT) is not only convenient for the driver
but also reduces hybridization costs because the existing production line is used to produce the AT. However, it has low fuel
economy due to the torque converter. To overcome this disadvantage, this paper studies HEVs equipped an AT without a torque
converter. In this case, additional torque control is needed to prevent the driving quality from deteriorating. This paper
suggests three different torque control methods and develops a simulator for an HEV that can simulate the dynamic behaviors
of the HEV when the engine clutch is engaged. The HEV drive train is modeled with AMESim, and a controller model is developed
with MATLAB/Simulink. A co-simulation environment is established. By using the developed HEV simulator, simulations are conducted
to analyze the dynamic behaviors of the HEV according to the control methods. 相似文献

This paper focuses on the dynamic modeling and control of engine starting for a Full Hybrid Electric Vehicle (FHEV) consisting of an Integrated Starter Generator (ISG) and Dual Clutch Transmissions (DCTs). The dynamic characteristics of the engine, the ISG motor and the main clutch are analyzed respectively. The dynamic models of the main components of the powertrain system are also established taking the system dynamic characteristics into consideration. The FHEV dynamic model of engine starting during electric driving mode has been investigated in detail. The coordinated control strategy of engine starting has been proposed based on the powertrain system dynamic characteristics. The simulation for the engine starting control during electric driving mode has been performed based on the Matlab/Simulink platform. The simulation results show that the proposed control strategy satisfies the requirements of response and smoothness during engine starting process. Furthermore, a bench test has been carried out to analyze the system characteristics during engine starting process. The test data is highly agreeable to the simulation data and the effectiveness of engine starting control strategy is validated by the comparison between simulation results and the test data. 相似文献
