    摘要: A motor-vehicle engine suspension elastic device has a main body of metal and/or composite material elongated in a direction parallel to the longitudinal direction of the motor-vehicle. The elastic device has a first end that can be connected to a structural connecting element of a motor-vehicle, and a second end that can be connected to a motor-vehicle engine. The main metal body of the elastic device includes at least one portion elastically deformable in the aforesaid longitudinal direction.

    摘要: An actuating system of an engine valve comprises a movable member, for example, in the form of a master piston controlled by a cam of a camshaft. A slave piston is hydraulically controlled by the master piston by means of a volume of pressurized fluid, to open said engine valve against the action of a return spring. The system also comprises an auxiliary device for applying an additional force to the engine valve to keep the engine valve in a closed position. The auxiliary device is configured or controlled in such a way that the total force tending to keep the engine valve in its closed position varies during each rotation cycle of the cam. The total force is higher at least in one part of the rotation cycle of the cam wherein the engine valve must remain in its closed position, and is, instead, reduced at least in one part of the rotation cycle of the cam wherein the engine valve is not in its closed position.

    摘要: In a method for detecting corrosion of a surface not exposed to view of a metal piece, radiant thermal energy is directed against the piece by pulsed laser beam illumination thereby causing heating of said piece. Infrared radiation emitted by the piece is detected by a thermographic camera so that corroded portions of said surface are detected due to a different thermal response as a function of time relative to non-corroded portions. The laser beam is directed against an exposed face of a wall of said piece whose opposite face is the surface on which corrosion must be detected. The thermographic camera is provided on a same side where a laser head for emitting said laser beam is provided and has a control system for performing “Lock-in” thermography. Detection of the surface corroded portions is carried out by comparing a response of different surface portions during cooling of the piece.

    摘要: An automotive electronic control system configured to detect and signal the presence of a passenger left unattended in a motor vehicle based on signals from an automotive sensory system comprising: one or more radar sensors arranged in the passenger compartment of the motor vehicle to allow the presence of one or more passengers sitting on one or more seats of the motor vehicle to be determined, one or more door sensors associated with one or more doors of the motor vehicle to allow locking and unlocking, and opening and closing, of one or more doors of the motor vehicle to be determined; one or more seat sensors associated with one or more seats of the motor vehicle to allow the presence of one or more passengers sitting on one or more seats of the motor vehicle to be determined; one or more safety belt sensors associated with one or more safety belts of the motor vehicle to allow fastening and unfastening of one or more safety belts to be determined; the automotive electronic control system is configured to: receive signals from the automotive sensory system; determine when the doors of the motor vehicle are unlocked; when the doors of the motor vehicle are determined to have been unlocked, determine whether a door of the motor vehicle has been opened for a sufficient length of time compatible with a passenger getting in the motor vehicle; if a door of the motor vehicle is determined to have been opened for a sufficient length of time compatible with a passenger getting in the motor vehicle, signal a potentially hazardous situation due to the presence of a passenger in the motor vehicle according to a first signalling mode or by means of a first signalling device; determine when the door of the motor vehicle has been closed; when the door of the motor vehicle is determined to have been closed, determine occurrence of a switch from a key-on state to a key-off state of the motor vehicle; if no switch from a key-on state to a key-off state of the motor vehicle is determined to have occurred, activate one or more radar sensors to check for the presence of the passenger in the motor vehicle; if the passenger is determined not to be on the motor vehicle based on the radar sensors, interrupt the signalling of the presence of the passenger in the motor vehicle; if instead the passenger is determined to be on the motor vehicle based on the radar sensors, signal the presence of the passenger in the motor vehicle according to a second signalling mode and/or device different from the first signalling mode and/or device.

    摘要: A fuel saving-aimed motor vehicle driver assistance system configured to receive and process motor vehicle-related data and motor vehicle position-related data to identify recurrent routes of a motor vehicle and to provide a motor vehicle driver, via an automotive human-machine interface, with motor vehicle driving assistance recommendations for fuel saving along the routes. The motor vehicle driver assistance system is configured to identify recurrent routes of the motor vehicle by determining a succession of geographic points, referred to as Waypoints, along a route of the motor vehicle, at which values of a series of physical quantities are determined and recorded, which define the attributes of the Waypoints. The Waypoint attributes are then updated when the vehicle travels through them. For each current motor vehicle position, a search is made for the Waypoint spatially closest to the current motor vehicle position and having certain characteristics, such that if such a Waypoint is not found, then a new Waypoint is defined, or else, if such a Waypoint is found, then variable Waypoint attributes are updated. The so-defined Waypoints are then concatenated so as to form an ordered list of Waypoints belonging to the same recurrent route. The characteristic points of the routes, such as bends, roundabouts and traffic lights, are identified and optimal speed profiles and primary controls for the motor vehicle at the characteristic points are computed. Based on the computed optimal speed profiles and primary controls and by means of the automotive human-machine interface, the motor vehicle driver is then provided with motor vehicle driving recommendations for fuel saving along the routes.
