    Abstract: A device for controlling a gearbox includes a transmission member that transmits movement of a control lever to a control cable. A locking member, having a first and second portions for locking the lever in respective park and neutral positions, is mounted in a device casing. An actuator causes the locking member to rotate when the lever must be unlocked from park position and when the lever must be locked in neutral position. The device includes an anti-locking pawl mounted on the transmission member, having an operative position preventing the second portion from being received in a transmission member seat for locking the lever in the neutral position. If the lever is freed from park position and moved through the neutral position while the actuator is active, the pawl is pushed by the locking member into its operative position, thereby preventing unwanted locking of the lever in the neutral position.

    Abstract: An automotive active brake noise damping system to actively damp braking noise perceivable in the passenger compartment of a motor vehicle comprising a braking system comprising a plurality of braking assemblies associated with wheels of the motor vehicle. The automotive active brake noise damping system comprises a sensory system to sense quantities that allow braking noise perceived in the passenger compartment of the motor vehicle and generated by the braking assemblies during braking to be estimated, an audio system to diffuse sounds in the passenger compartment of the motor vehicle, and an electronic control unit connected to the sensory system and the audio system, and programmed to control the audio system based on the quantities sensed by the sensor system to actively damp the braking noise perceived in the passenger compartment of the motor vehicle. The sensory system comprises vibration sensors, conveniently in the form of piezoelectric accelerators, which are applied to the braking assemblies to sense the amplitude of the vibrations generated by the braking assemblies during braking, and the electronic control unit is programmed to store a mathematical model, which correlates vibrations generated by the braking assemblies during braking with corresponding braking noise perceived in the passenger compartment of the motor vehicle and produced by the braking assemblies during braking, estimate the braking noise perceived in the passenger compartment of the motor vehicle and generated by the braking assemblies of the braking system during braking as a function of the vibrations generated by the braking assemblies during braking and sensed by the vibration sensors applied to the braking assemblies and of the stored mathematical model, compute an interfering sound to be diffused in the passenger compartment of the motor vehicle to damp the braking noise perceived in the passenger compartment of the motor vehicle and generated by the braking assemblies during braking, and control the audio system to cause it to diffuse the computed interfering sound.

    Abstract: A motor-vehicle floor panel structure comprises a front body sub-unit, a central floor sub-unit, and a rear body sub-unit. The central floor sub-unit comprises a front floor structure including a central longitudinal tunnel, a pair of lateral longitudinal beams, connected to the front floor structure and to the front body sub-unit and two intermediate longitudinal beams which connect the central floor sub-unit to the front body sub-unit and which extend at intermediate areas between the lateral longitudinal beams and the central tunnel. The intermediate longitudinal beams are connected to the upper surface of the front floor structure and have portions which extend in a cantilever fashion from the front edge of the front floor structure and which are connected to said front body sub-unit. Due to this feature the floor structure has a lower surface which is substantially close to a regular continuous surface, so as to reduce turbulences in the air flowing under the floor panel structure during travel of the motor-vehicle, with a resulting positive impact on fuel consumption.
