Abstract: A method for estimating the end-of-stroke positions of moving members of electromagnetic actuators for the actuation of intake and exhaust valves in internal combustion engines in which an actuator is coupled to a respective intake or exhaust valve and comprises a moving member actuated magnetically in order to control the movement of the valve, a sensor supplying a position signal representative of a current position of this moving member and a first and a second electromagnet disposed on opposite sides of the moving member, wherein this moving member can move between a first end-of-stroke position in which it is disposed in contact with the first electromagnet and a second end-of-stroke position in which it is disposed in contact with the second electromagnet. The method comprises the stages of checking whether the condition of stationary contact of the moving member exists and determining a magnitude correlated with this current position, if the stationary condition is verified.

Abstract: An electric motor including a rotor, rotating about an axis of rotation, and a stator, coaxial to the rotor. The stator has a casing. A body incorporates a controller of the electric motor. The body is placed outside the stator and parallel to the axis of rotation in a position substantially tangent to the casing of the stator. The rotor includes a first and second cooling fan, keyed on respective first and second axial ends of the rotor, opposite along the axis of rotation. The first and second cooling fans generate respectively, with the rotation of the rotor, a first and a second flow of cooling air independent of each other. The first flow of cooling air is directed toward the first axial end of the rotor, and the second flow of cooling air is directed towards the body so as to cool down the controller.

The main electronic switch M1 has a first electrical terminal D1, a second electrical terminal S1, and a main driving terminal G1. The main electronic switch M1 is adapted to take, based on a driving signal DRV, depending on the command signal CMD and on an enabling signal ENB, a closed condition or an open condition, wherein the first electrical terminal D1 is respectively connected to or disconnected from the second electrical terminal S1. The pre-charge electrical circuit is adapted to carry out, based on the command signal CMD, a pre-charge operation, aimed at equalizing the electric potentials (V1, V2) of the first and second terminals of the device, before the main electronic switch M1 takes a closed condition, upon of a transition from the open condition.

Abstract: A method for recognizing the driving style of a driver of a land vehicle, of the type that envisages acquiring information on the dynamics of the vehicle from sensors and calculating, as a function of said information on the dynamics of the vehicle, a class of membership of the driving style of the driver. The method comprises the steps of analysing information on the dynamics of the vehicle to start a procedure of recognition of the event that comprises: reconstructing a manoeuvre performed by the driver; identifying the manoeuvre performed, by comparing said displacement time series with models of time series corresponding to pre-determined manoeuvres stored in a database; defining regions in a cartesian plane having as axes a lateral acceleration and a longitudinal acceleration, in particular manifolds; computing cost functionals for the three driving styles; and recognising the driving style, on the basis of said cost functionals.
