Abstract: In the application development of continuously variable transmission (CVT) project, system-level durability test is one of the essential product design verification.This paper briefly introduces structure and working principle of CVT, and establishes a durability test method for CVT based on dSPACE DS1006 real-time platform, and the database is imported through MATLAB, the real-time control models are established by Simulink, and the automatic operation of the test is realized by Python. Examples are given to illustrate the method of monitoring the limit value of important parameters of the transmission during the test. This control system has high control accuracy and improves verification quality.
