    Abstract: A method for operating an automobile vehicle pedestrian sensing system includes: embedding multiple piezoelectric sensors in a vehicle bumper fascia, each generating a voltage in response to an impact of an object with the fascia; retrieving multiple threshold values from a memory, each assigned to one of the sensors; reading the voltage from each of the sensors; grouping individual sensors into multiple different logic circuits, each including at least two of the sensors; determining for each sensor in each of the logic circuits if the voltage is greater than the assigned threshold value; creating a positive signal following any one of the logic circuits when the voltage is determined to be greater than the assigned threshold value for the sensors grouped into the one of the logic circuits; and generating a hood deployment system deployment signal when the positive signal is output from all of the logic circuits.

    Abstract: A vehicle hood covering an underhood object includes an inner surface of the vehicle hood facing the underhood object and spaced from the underhood object, and an outer surface of the vehicle hood opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the vehicle hood. The local energy absorber is a multiply-connected structure. The local energy absorber includes a wall defining an interior surface having symmetry about a central plane normal to the inner surface of the vehicle hood. A plurality of apertures is defined in the wall symmetrically about the central plane to initiate buckling and fracture in the wall during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.

    Abstract: An approach to designing lightweight metal-polymer composite structures in a manner that decomposes the structure into at least two parts. In one specific embodiment, the approach is a manufacturing process for a vehicle that includes attaching an impact beam to a vehicle structure. The process includes providing a vehicle structure including a back plate of the impact beam being made of a suitable material, such as a metal, that can withstand high temperature processes. A front part of the impact beam including a front plate and a polymer core is attached to the back plate. The back plate is designed to provide structural integrity that allows the vehicle structure to go through the high temperature processes and/or the vehicle structure provides structural integrity that allows the back plate to go through the one or more processes. The back plate is also designed to provide desired functional characteristics of the beam.

    Abstract: A vehicle includes a first vehicle component having a shape memory polymer (SMP) including a first modulus of elasticity in a first state and a second modulus of elasticity in a second state, the second modulus of elasticity being less than the first modulus of elasticity, a heating element selectively movable from an OFF state to an ON state to supply the SMP with heat, the SMP moving from the first state to the second state in response to the heating element moving from the OFF state to the ON state, and at least one sensor attached to the vehicle and configured to generate an electric signal in response to a force of a predetermined magnitude being applied to the vehicle to move the heating element from the OFF state to the ON state.
