| Abstract;HILS has been introduced to the CVT ECU development process in an attempt to increase efficiency. To create HILS, it was necessary to develop a CVT HILS model capable of simulating transient states in a CVT shift mechanism, including a hydraulic control system. The calculation burden of the model was required to be low enough to enable real-time simulation. The aim of this project was to develop an experimental model capable of calculating the transient characteristics of the pulley ratio on the basis of pulley ratio, the torque input to the pulley, and the speed of revolution of the pulley; in order to enable simulation of transient states, in particular in kick-down shift. Given the high calculation load of the hydraulic control system model, test data was employed to enable the higher order simultaneous equation model to be replaced by a lower order transfer function model. The newly developed HILS has been successfully introduced to the development process for CVT ECU, resulting in a 30% reduction in the number of procedures required for verification of functioning and setting parameters for programs.
