Abstract: A steering assembly comprises a support structure designed to be coupled to a chassis of a road vehicle and extending along a longitudinal axis; a coaxial sleeve, slidingly movable with respect to the support structure; a steering column, coaxial and internal to the sleeve, comprising a portion capable of rotating with respect to the sleeve and slidingly movable, together with the sleeve, with respect to the support structure; and a retaining element, which is fixed to the support structure and to the sleeve at two ends, respectively, has a length such that it limits a sliding of the sleeve in a departing direction away from the support structure to a predefined limit sliding value and is flexible to allow the sleeve to slide in an approaching direction.

Abstract: An electric machine stator has a casing defining an internal cavity housing a core made of ferromagnetic material, arranged axially between two chambers communicating respectively with an inlet conduit and with an outlet conduit, to receive and discharge a heat exchange liquid; the core consists of a plurality of teeth arranged about a longitudinal axis and circumferentially defining between each other a plurality of slots engaged by coils made of electrically conductive material, wound around the teeth; the two chambers in the stator communicate with each other through the slots and through a plurality of channels formed in the teeth; the stator also has an adjustment device configurable to achieve a first configuration, in which it allows passage of the heat exchange liquid in the channels, and a second configuration, in which it prevents passage of the heat exchange liquid in the channels.

Abstract: An electric motor comprises a stator and a rotor rotatable around a rotor axis fixed with respect to the stator. The rotor comprises a phase change material solid or semi-solid at ambient temperature and adapted to liquefy at a liquefaction temperature within a range of operating temperatures of the electric motor.

Abstract: A road vehicle includes a frame and four wheels. For each wheel there is a suspension unit connecting the corresponding wheel to the frame. At least one of the suspension unit is an active suspension unit comprising: a rocker arm coupled to the frame in a rotary manner around a pivot with an axis A substantially parallel to the longitudinal direction of development of the vehicle; a suspension rod having a first end coupled to the rocker arm on the wheel side and a second end coupled to the wheel; a rod damper with a variable length along an axis A? having a first movable end coupled to the rocker arm and a second fixed end coupled to the frame; an electric motor configured to generate a rotational torque to rotate the rocker arm around the pivot; wherein the electric motor acts directly upon the rocker arm at the pivot.

Abstract: Road vehicle having a longitudinal direction parallel to the direction of travel and a transverse direction perpendicular to the longitudinal direction; the road vehicle comprises a steering wheel inside the passenger compartment on the driver's side; a dashboard and a steering column on one side connected to the steering wheel and on the opposite side connected to the dashboard; wherein the dashboard comprises: a supporting plate behind the steering wheel that supports human-vehicle interface controls and a first information display screen; a central information display screen along the transverse direction at the side of the supporting plate toward the passenger; wherein the plate and the central screen are integrated with each other in a single structure.

Abstract: A body part for a road vehicle comprising an outer portion configured to be arranged on the outer side of a road vehicle and defining a first side of the roof panel; an inner portion configured to be arranged, with respect to the outer portion, towards a passenger compartment of the road vehicle and defining a second side of the roof panel; wherein the outer portion comprises one or more first composite material layers, each comprising a reinforcement texture; wherein the outermost layer of said one or more first composite material layers, i.e. the one visible, in use, from the outside of the road vehicle, comprises a plurality of metal filaments woven into the reinforcement texture.

Abstract: There is described a seat for a motor vehicle comprising a backrest, a seat cushion and a first bellows interposed between the backrest and the seat cushion, so as to allow the relative position between the backrest and the seat cushion to be adjusted.

Abstract: A vehicle has at least one axles with wheels operated by at least one electric motor; a sound transmission system transmits a sound indicative of the operation of the axle inside the passenger compartment; said sound transmission system has at least one acoustic conduit provided with an inlet mouth arranged in the area of the axle and/or of the electric motor and with an outlet opening arranged in the area of the passenger compartment.

Abstract: Method for controlling the injection of a coolant into a combustion chamber (of an internal combustion engine of a motor vehicle. The method comprises the steps of: acquiring at least one electrical signal, determining a corresponding quantity indicative of the rate of the combustion reaction within the internal combustion engine based on the acquired electrical signal associated with the operation of the injectors, verifying that the quantity indicative of the rate of the combustion reaction within the internal combustion engine meets a control criterion. If the quantity indicative of the rate of the combustion reaction within the engine meets the control criterion, performing first actions to control the injection of coolant into the combustion chamber. If the quantity indicative of the rate of the combustion reaction within the internal combustion engine does not meet the control criterion, performing second actions to control the injection of coolant into the combustion chamber.

Abstract: A hydrogen internal combustion engine is provided with at least one cylinder (having an inlet to feed oxidizing air into the cylinder and with an outlet to let combustion gases out of the cylinder, at least one piston engaged in a sliding manner in the cylinder, and an injection unit to feed fuel hydrogen into the cylinder; the injection unit having a feeding manifold, which extends around at least part of a side wall of the cylinder, and communicates with the cylinder through a plurality of feeding holes obtained through the side wall of the cylinder.

Abstract: Method for determining the drowsiness/attention level of the driver of a road vehicle; the method comprises the steps of: detecting at least one steering parameter related to the kinematics of a driver-operated device for steering; where the steering parameter is related to the steering angle and/or the steering speed of the road vehicle; elaborating a steering index as a function of the at least one steering parameter detected; detecting at least one line parameter related to the position of the road vehicle within a lane; processing a line index as a function of the at least one line parameter detected; computing a driver drowsiness/attention index as a function of a combination of the steering index and the line index.
