Automatic transmission control system of TCU performance directly affect the performance and fuel economy of the vehicle and driver experience, and these parameters are decided directly by the TCU application software, especially the control strategy, so the control strategy is the key to the electronic control system of TCU. TCU control system controlled by the clutch, shift control, engine to take over the control, coordination control and the top layer control and so on several parts, according to certain control law, realize the vehicle start, such as lifting gear closed loop control of the process.
ATMaster is in view of the automatic transmission model, control algorithm based on MATLAB/Simulink development, can realize the different actuator of the automatic transmission control, model adopts modular structure, hierarchical structure is clear, according to the different actuator increase or cut the corresponding function module, to achieve the goal of automatic transmission control requirements. ATMaster is a control algorithm model for automatic transmission TCU. The overall structure of the model is as follows:
The advantages of using ATMaster as an automatic transmission TCU application software solution include:
• An automatic transmission control algorithm based on the coordination control layer is presented.
• The algorithm is adaptable and can match the automatic transmission of different types of actuators
• Based on MATLAB/Simulink development, the model is hierarchical and readable
• Modular model structure, easy to reduce or add functional modules
