    The present invention relates to a method (100) for controlling the propulsion modes of a boat of the type comprising a power controlled motor (21), a group of sails (22) and a first plurality of sensors (23) of the wind conditions and of the motion conditions of the boat, the method being characterized in that it comprises the steps consisting in detecting (101) a plurality of typical parameters of the wind conditions through the first plurality of sensors (23), verifying (102) whether the plurality of typical parameters of the wind

    Coordinated lateral and longitudinal vehicle dynamics control of a scale RC vehicle

    This paper addresses the design, implementation and validation of a coordinated lateral and longitudinal dynamics control for a racing four-wheel driven RC vehicle. The coordination is achieved hierarchically: a wheel slip control loop stabilizes the fastest longitudinal dynamics, so that the outer lateral dynamics control can rely on non-saturated tires. Designing a wheel slip controller on a scale model requires the estimation of the wheel slip using a reduced set of sensors. The issue of estimating the wheel slip on such a small vehicle is addressed using a complementary filter. The presence of the inner wheel slip control enables the use of a simple gain-scheduled yaw-rate controller to stabilize the yaw rate dynamics and make the yaw rate gain velocity independent. The combined longitudinal and lateral controller is experimentally tested, using both repeatable tests with precomputed inputs and human-in-the-loop tests. The experimental results indicate that the controller is able to extend the operating envelope of the vehicle yielding an easier to operate vehicle

    A Planar Electric Vehicle with Differential Steering and a PlantarCommand

    This paper focuses on a new electric and compact vehicle with a differential steering and a sensitive plantar as driving command. The mechanical, electronic and software architecture are presented. A special focus is given to the sensitive surface of the vehicle chassis which allows the user to drive the vehicle by unbalancing his or her center-of-gravity (COG). The design of the plantar is herein outlined: the electronic system is described and the algorithm to estimate the COG position is proposed. Some experimental results about the sensitive plantar are reported
