Modeling and Performance Analysis of a 10-Speed Automatic Transmission for X-in-the-Loop Simulation

Abstract Details

2018, Master of Science, Ohio State University, Mechanical Engineering.
Vehicle integration testing has been increasingly front-loaded in the automotive development cycle to reduce prototyping and testing costs. One method of performing these tests is X-in-the-loop integration, which allows a verification and validation workflow from the design of control algorithms in offline high-fidelity models (MIL) to the online integration verification with prototype control hardware (HIL). A 10-speed automatic transmission is used as an example to traverse the gap between an offline high-fidelity model and a real-time capable online model. The model is split into three subsystems and each is built up from the component level using one-dimensional mechanics and zero-dimensional hydraulic fluid flow. The high-fidelity model parameters are perturbed to judge sensitivity of output performance metrics. The model is reduced by removing higher-order derivatives and faster dynamics at the component level. Multiple reduced models were generated and tested for errors relative to the high-fidelity version and increases in model execution speed. After reduction, a full automatic transmission model with hydraulic actuation circuit and dynamic torque converter has been implemented on a dSpace HIL simulator for real-time testing without control hardware in the loop.
