摘要： A method of controlling a pickup manoeuvre of a hybrid vehicle is actuated with an engine off, an electric motor active and a first clutch being open. In a first phase of the manoeuvre, vehicle advancement is obtained by progressively closing the second clutch so that the input shaft is set in rotation with an increasing speed, while the motor rotates at an increasing speed higher than a speed of the input shaft with the second clutch in a slip condition. Upon a request for starting the engine, the first clutch is progressively closed so that the engine starts to be driven by the motor, while the second clutch is kept in the slip condition, which is maintained until the engine and motor rotate substantially at a same speed, higher than the speed of the input shaft, and once this condition is reached, closing of the second clutch is started.

摘要： A light duty vehicle includes a vehicle frame, including a pair of vehicle longitudinal beams connected to each other by a plurality of cross-members and a cabin frame, having a pair of cabin longitudinal beams rigidly connected to front ends of the vehicle longitudinal beams. A supporting structure for auxiliary units, such as gaseous fuel tanks or electric batteries, which is carried by the vehicle frame, and includes an auxiliary frame extending between the vehicle longitudinal beams and having connection plates arranged in vertical planes parallel to a longitudinal direction of the vehicle frame and which are in contact with mutually facing inner lateral walls of the vehicle longitudinal beams and are rigidly connected to these longitudinal beams. The auxiliary frame fulfills a structural function equivalent to the structural function of one or more cross-members at an area of the vehicle frame where the cross-members are omitted.

摘要： A connection system for connection of two or more overlapping layers of material includes: a rivet having a head and a stem, the head being configured to bear upon a surface of a first layer of the layers of material, the stem having an outer surface that includes a surface sculpturing and being configured for passing through the layers of material and projecting beyond them; and a washer configured to fit on the stem and configured to bear upon a surface of a last layer of the layers of material, the washer being deformable by axial compression from an undeformed condition where it fits on the stem with play, to a deformed condition where it fits on the stem in a condition of interference with the outer surface of the stem. Moreover described is a corresponding method for joining the layers of material using the connection system.

摘要： A method for moulding a sheet into a component of complex shape having areas with different mechanical properties, particularly a motor-vehicle component, includes a first heating step of the sheet carried out by a kiln, prior to forming the component. The kiln has a main body with a roller shape, having a plurality of sectors extending along a radial direction with respect to a longitudinal axis of the roller body. The sectors are configured to each receive a sheet, so that the main body with a roller shape is arranged to simultaneously carry a plurality of sheets. The kiln includes a plurality of heating elements incorporated in the roller-shaped main body, so as to heat the sheets in contact with the roller body. The kiln includes at least one electronically-controlled drive motor, arranged to rotate the roller-shaped main body around the longitudinal axis of the kiln, so as to vary the position of the sectors with respect to the inlet and outlet ports. An additional heating step follows extraction of the sheets from the kiln, wherein the sheets are locally heated only at one area, so as to obtain sheets with areas heated to different temperatures.

摘要： A hinge of a motor-vehicle mobile part includes a first and a second hinge element mounted articulated with respect to each other about a hinge axis. The second hinge element is articulated to the first hinge element by an articulation portion having two pins defining the hinge axis, and projecting in opposite directions from two sides of the second hinge element. The first hinge element and the second hinge element are obtained by an additive manufacturing technique in an already reciprocally articulated condition, with the pins mounted with clearance within respective articulation seats formed on two flanges of the first hinge element adjacent to the sides of the second hinge element. The hinge also includes two bushing-shaped members, each interposed between one of said two pins and the respective articulation seat.

摘要： A deformation detecting device includes weft yarns and warp yarns woven together. At least some of the weft yarns, or some weft yarns, and some warp yarns, are electrically conductive. The weft yarns include a flocking made up of non-electrically conductive fibers protruding substantially radially from the weft yarns. The electrically conductive yarns are connected to conductive ends for applying an electrical voltage, such that yarns that are connected to conductive ends with different polarities define respective plates of a capacitive sensor, while the fibers of the flocking of the weft yarns define a dielectric material interposed between the capacitive sensor plates. The device comprises an electronic control and processing unit configured to detect a deformation of the fabric based on a capacitance variation of the capacitive sensor.

摘要： An advanced driver assistance system designed to receive and process motor-vehicle position-related data and motor-vehicle motion-related data of a host motor vehicle and of neighbour motor vehicles detected in the vicinity of the host motor vehicle and which have been determined as entering the same roundabout in which the host motor vehicle will enter, to provide assistance to the driver of the host motor vehicle for negotiating the roundabout. A degree of proximity of the host motor vehicle and the neighbour motor vehicle to the roundabout based on motor-vehicle position-related data is determined and a determined alert level is provided the driver.

摘要： A sealing and/or guiding seal for a motor-vehicle window or other movable part of a motor-vehicle, includes at least one body formed of polymeric elastomeric material supplemented with carbon-based nanofillers. The body includes an outer surface with one or more piezo-resistive areas where the polymeric material supplemented with carbon-based nanofillers has been made locally piezo-resistive by laser irradiation. One or more electric deformation sensors are defined so as to detect an interference with an unrelated body during the movement of the movable part of the motor-vehicle. The body also includes one or more conductive paths where the polymeric material supplemented with carbon-based nanofillers has been made locally electrically-conductive by means of laser irradiation, so as to define one or more electrical connection lines of the piezo-resistive areas with electrodes associated with the seal.
