Electro-mechanical clutch-by-wire control for sport motorcycles

By-wire technologies are extremely appealing, as they allow a fully adjustable modulation of the actuation system, together with better potential performance than their wired counterparts. In this work, a novel electro-mechanical layout for a full by-wire management of a motorcycle clutch system is presented, and the related control problem is addressed. Comparing the new system with a more traditional electro-hydraulic setup that was previously studied, it results easier to control and it provides a better riding feeling. Experimental results on an instrumented vehicle demonstrate the effectiveness of the proposed approach.
