摘　　要：通过对液力自动变速传动系统进行建模仿真,建立了传动系统的换挡规律和油门控制规则,开发了基于Simulink仿真程序的dSPACE控制程序,并以dSPACE作为中央控制器,进行了液力自动变速传动系统动力性匹配控制试验,结果表明,应用所制订的控制策略实现了液力机械自动变速传动系统的良好匹配控制。By establishing models and making simulation of hydraulic automatic transmission system, the shift rule of transmission system and throttle control regulation is made, a dSPACE control program based on Simulink software is developed, using dSPACE as the centre controller. The power performance matching control experiment of hydraulic automatic transmission system is carried out. The result shows that well matching performance of hydraulic automatic transmission system can be realized by using the control strategy proposed in this paper. It provides a fast and efficient approach for researching and developing the hydraulic automatic transmission system.
