Discussion on: 'Experimental Identification of the Engine-to-Slip Dynamics for Traction Control Applications in a Sport Motorcycle'

摘要

The paper by Corno and Savaresi considers the problem of modelling the engine-to-slip dynamics and presents a protocol for their identification on a sport motorcycle. These dynamics are important for a proper design of traction control (TC) as well as to estimate its performance and feasibility. These dynamics were not properly investigated in the open scientific literature and therefore the experimental identification carried out in the paper represents an interesting contribution. Anyway, because of the black-box approach the work does not correlate the properties of the identified describing functions (frequency and damping of resonances, phase lag, etc.) to the physical characteristics of the vehicle such as engine inertia, tyre geometry, etc. Even if this is not the goal of the paper, in our opinion this correlation is essential to extend the results to other vehicles, different motion conditions and to give TC designers helpful hints. In other words, to make the results more general and not limited to the tested vehicle and tested condition only.
