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.
