Validation of Mechanical Transmission with Clutch using Hardware-In-the-Loop Simulation

A hardware-in-the-loop (HIL) simulation of a conventional vehicle system is developed for experimental validations of clutch modelling. Two different states have to be taken into account in this system: clutch locked and slipping. Two different models are then used and a specific condition defines the commutation between both models with respect to the physical energy flow. Energetic macroscopic representation (EMR) is used to organize the numerous blocks required. A Petri net is employed to activate a model according to clutch state (lock and slip). The HIL is based on a controlled IM drive, which imposes the same behaviour of the mechanical power-train to the clutch. A flexible and dynamical model of the whole system is used and simulation results are provided with regard to the experimental results.
