摘要: An active material hood impact mitigation mechanism is activated in response to a signal generated from an impact sensor or pre-impact sensor or manually. The mitigation mechanism is capable of changing either reversibly or irreversibly the stiffness, shape, location, orientation, or displacement force of the hood either globally or locally, before an impact against the hood. The active material mitigation mechanism is held in a device designed to be installed in operative communication with the hood surface. The active material is characterized by a first shape or stiffness and is operative to change to a second shape or stiffness in response to the activation signal. Such active materials include shape memory alloys, electroactive polymers, shape memory polymers, magnetic shape memory alloys, magnetorheological fluids, magnetorheological elastomers, electrorheological fluids, and piezoelectric materials.

摘要: A wet road surface detection system is provided for a vehicle driving on a road. The wet road surface detection system includes a sound sensing device coupled to the vehicle for capturing noise of the vehicle tires as the vehicle drives on a road surface. A processor processes sounds captured by the audible sensing device. The processor quantifies a variable sound level of the captured noise between a first frequency and a second frequency. The processor determines whether each quantified sound level between the first frequency and the second frequency is above a predetermined sound level threshold below the sound level at the first frequency. The processor determines that the vehicle is driving on a wet road surface in response to each quantified sound level between the first frequency and the second frequency being above a predetermined sound level threshold below the sound level at the first frequency.

摘要: An energy absorbing device is provided that includes a damper assembly having inner and outer concentric tubes and a piston movable within the inner tube. The damper assembly is configured to form bi-fold valve-type cavities to operatively connect an inner chamber of the inner tube with an outer chamber formed between the inner and outer tubes. A magnetorheological fluid fills the chambers and the bi-fold valve-type cavities. The magnetorheological fluid preferably contains coated magnetic particles at about 10 to 60 percent by volume. Electrical coils adjacent the bi-fold valves are selectively energizable to such that the energy absorbing device provides a tunable damping force, preferably over the entire range of velocities of the piston, especially in automotive applications.
