Problems solved by technology

However, when performing hardware-in-the-loop real-time simulation, since the clock frequency of the simulation hardware controller is fixed, the simulation model completed by using the modular modeling tool can only perform fixed-step simulation. The model (such as DCT transmission system simulation) is too complex. At certain moments when the simulation model completed by the modular modeling tool is running, there must be high-frequency components in the system, which may cause system oscillations, simulation results do not converge, and errors accumulate and magnify.

Description

technical field [0001] The invention relates to automobile development and testing technology, in particular to a method for building a simulation model of an automatic transmission drive system. Background technique [0002] At present, there are mainly two methods for developing and testing the functions of automatic transmission controllers: road test and simulation analysis. The road test consumes a lot of manpower and material resources, increases the development cost, and eventually leads to the delay of the development cycle of automatic transmission controllers. increase. The use of simulation technology can verify the effectiveness of the control strategy and detect defects in the controller software at an early stage, improve the quality of software development, and speed up the development progress. The use of simulation technology to assist the development of automatic transmission controllers is based on the simulation model of the automatic transmission transmi...
