Disclosed herein is a composite panel for sound absorption that may absorb and block noise. The composite panel may include: a first perforated panel comprising first embosses and first perforation groups formed in a predetermined pattern, wherein the first embosses are formed by forming a plurality of cells and the first perforation groups are formed by collecting a plurality of first perforated holes; an embossed panel comprising second embosses formed by forming the plurality of cells and coupled to the first perforated panel wherein the embossed panel is laminated with the first perforated panel; and a sound absorbing and insulating material inserted between the first perforated panel and the embossed panel.

A vehicle panel assembly for a motor vehicle and carrier module therefor are provided. The vehicle body panel assembly includes a structural panel body defining an internal cavity with the carrier module secured to the structural panel body at least partially in the internal cavity. The carrier module has a carrier with an actuator attachment region integrally formed thereon and providing a first attachment feature. A latch assembly is secured to the carrier module and an actuator is configured in operable communication with the latch assembly to selectively cinch the latch assembly. The actuator has a housing providing a second attachment feature, wherein the first and second attachment features are configured for attachment to one another.

A sound control method includes altering at least one characteristic of power delivered within an electrified vehicle powertrain to cause at least one component of the electrified vehicle powertrain to emit different acoustic tones that follow a predetermined sequence. A sound control assembly includes a power characteristic control system that alters at least one characteristic of power delivered within an electrified vehicle powertrain to cause at least one component of the electrified vehicle powertrain to emit different acoustic tones that follow a predetermined sequence.

A fuel cell system includes a fuel cell, an air pump which supplies air to the fuel cell, a passenger presence or absence determination unit which determines the presence or absence of a passenger in a vehicle in which the fuel cell and the air pump are installed, a discharge flow rate determination unit which determines a discharge flow rate of the air pump when the fuel cell is warmed up, in accordance with the presence or absence of the passenger in the vehicle, and a control unit which controls the air pump on the basis of the discharge flow rate determined by the discharge flow rate determination unit.

A splitter system for a vehicle having a vehicle body including a first vehicle body end configured to face oncoming ambient airflow when the vehicle is in motion includes first and second splitter portions. The first splitter portion is configured to be fixed to the vehicle body. The second splitter portion is mounted to the first splitter portion. The first and second splitter portions together are configured to generate an aerodynamic downforce on the vehicle body when the vehicle is in motion. The splitter system also includes a mechanism arranged between the first and second splitter portions. The mechanism is configured to vary position of the second splitter portion relative to the first splitter portion to thereby control movement of the oncoming ambient airflow relative to the vehicle body and vary a magnitude of the aerodynamic downforce.

A sound control method includes altering at least one characteristic of power delivered within an electrified vehicle powertrain to cause at least one component of the electrified vehicle powertrain to emit different acoustic tones that follow a predetermined sequence. A sound control assembly includes a power characteristic control system that alters at least one characteristic of power delivered within an electrified vehicle powertrain to cause at least one component of the electrified vehicle powertrain to emit different acoustic tones that follow a predetermined sequence.

The present disclosure provides an engine mount for a vehicle. The engine mount includes a rubber assembly that is connected between a vehicle body and an engine. A fluid sealing assembly is detachably assembled to the rubber assembly, allowing tuning of the engine mount to be performed by detaching the fluid sealing assembly while the engine remains connected to the engine mount.

A system for controlling noise of a vehicle includes: an engine speed sensor configured for detecting a speed of an engine of the vehicle; a microphone detecting noise of the vehicle; an engine state sensor configured for detecting an operating state of the engine; a signal processing controller receiving the speed of the engine, the noise of the vehicle, and the engine operating state and generating amplified noise based on at least one of the received engine speed, the received noise of the vehicle, and the received engine operating state; a signal processing amplifier receiving the engine speed and the amplified noise and generating output noise by amplifying the amplified noise as much as amplification degree based on the speed of the engine; and a sound transmitting device receiving the output noise and transmitting the output noise or a separate sound source corresponding to the output noise to the vehicle.

A hydraulic mount for a vehicle includes: a core bush coupled to a bolt; a main rubber formed on an outer surface of the core bush; an orifice portion coupled to a lower portion of the main rubber so as to divide an upper fluid chamber and a lower fluid chamber, the orifice portion including a lower plate and an upper plate; and a membrane mounted between the lower plate and the upper plate. A fluid path is formed on an upper surface portion of the lower plate, a lower inlet and outlet port is formed on a predetermined position of the fluid path, an upper inlet and outlet port communicating with the fluid path is formed on the upper plate, a concave groove portion and a fixing end are repeatedly and uniformly formed along a circumference of the upper plate so as to cover the fluid path on the lower plate and be coupled thereto, and the membrane is exposed through the concave groove portion.

An outer mirror for a vehicle according to the technology of the present disclosure includes a mirror stay, a mirror visor, and a mirror for checking behind the vehicle. The mirror stay is provided at a vehicle body side face. The mirror visor is supported by the mirror stay and includes an opening portion at a vehicle rear side. The mirror is provided in the opening portion. In a horizontal section cut through the mirror visor, a distance between a vehicle width direction inner side face of the mirror visor and the vehicle body side face decreases toward the vehicle rear from a front end portion of the mirror visor.
