An apparatus and method for improving the safety and performance of an automobile in crash events is disclosed. The apparatus includes a front crash pad, rear crash pad, and a connection beam. Both crash pads and the connection beam are coupled to an automobile in such fashion as to absorb and dissipate energy by converting kinetic energy into strain energy.

Deflector are disposed below, in a vertical direction of a vehicle body, right and left ends of a front bumper to suppress flowing of traveling air from the from side into wheel houses. Splash shields are disposed between a pair of front side frames and a sub-frame to suppress flowing of the air from an engine room into the wheel houses. Ducts are provided at right and left ends of the front bumper. Each of the ducts includes an intake port that takes in the traveling air from the front side, and a discharge port that discharges the traveling air taken in from the intake port into the wheel houses.

A method for diagnosing the absence of an under-engine protection of a motor vehicle, includes: estimating a temperature of air external to the vehicle, estimating an under-hood temperature, determining whether the external-air temperature value is below the under-hood temperature value, in the affirmative, calculating an absolute value of a difference between the external-air temperature measurement and the under-hood temperature measurement, determining a diagnostic criterion by calculating a difference between the absolute value and a predetermined absolute value, obtained in the presence of the under-engine protection, comparing the diagnostic criterion against a predetermined diagnostic threshold, and emitting a diagnostic signal dependent on the result of the comparison.

The present invention discloses an integrally molded vehicular undercover having air permeability includes a base material layer containing inorganic fibers and a first solidified thermoplastic binder, the base material layer having a road side surface and a vehicle body side surface, an outer layer containing synthetic resin fibers and a second solidified thermoplastic binder, the outer layer being integrated with the road side surface of the base material layer, and a synthetic resin layer having air permeability, the synthetic resin layer being integrated with the vehicle body side surface of the base material layer.

A wheel resonator, which is provided by integrating a first member having a first welding surface with a second member having a second welding surface and includes a volume chamber and a communicating tube. The volume chamber has a flat shape and is configured to extend along an outer surface of a vehicle wheel when the wheel resonator is attached to the vehicle wheel. The first welding surface and the second welding surface are welded to each other, and are provided on a single welding plane. The welding plane extends in a circumferential direction and a width direction of the vehicle wheel when the wheel resonator is attached to the vehicle wheel, is a plane on which the volume chamber is divided into two volume portions, and is a plane on which the communicating tube is divided into two communication portions. The communicating tube extends along the welding plane.

A planar motor vehicle lining component made of a plastic-containing material, having a liner portion of predetermined shape which is embodied to cover, in the completely installed state, a predetermined area on a motor vehicle, the lining component includes at least one reinforcing portion that is connected to the lining portion and is connected by means of a hinge portion to the lining portion foldably in such a way that a supporting surface region of the reinforcing portion is conveyable, by folding over the reinforcing portion, into abutting engagement with an abutting surface region of the lining portion.

The present invention relates to non-woven fabric with enhanced hardness and sound absorption, more specifically to non-woven fabric that includes two or more kinds of polyester-based materials and non-circular cross-section fiber, and thus has enhanced hardness and sound absorption as well as improved formability, and that can be applied for an automotive undercover.

The present invention aims to provide a sound-absorbing material having sound absorption performance with an average sound absorption coefficient of 0.65 or more in the frequency domain of 800 to 2000 Hz. The present invention relates to a sound-absorbing material including: a fiber layer including a plurality of holes open to a surface thereof and having a thickness of 3 mm or more; and an inorganic material layer formed on the surface of the fiber layer, the holes being blind holes each penetrating through the inorganic material layer and having a bottom inside the fiber layer.

An automotive vehicle includes a body with a front portion, an underbody portion, a wheelhouse disposed in the underbody portion, and a front fascia disposed at the front portion. The wheelhouse is provided with a liner. A movable member is disposed between the wheelhouse liner and the front fascia. The movable member has a venting position and a barrier position. In the barrier position the front fascia, movable member, and wheelhouse liner define a generally contiguous surface, and in the venting position the movable member is displaced at least partly away from the body relative to the barrier position. An actuator is coupled to the movable member and configured to actuate the movable member between the venting position and the barrier position. A controller is configured to control the actuator to move the movable member to the barrier position in response to a first operating condition being satisfied.
