Abstract: A device for controlling an exhaust sound of a vehicle includes a sound tunnel mounted near a muffler and an exhaust pipe so as to transmit exhaust sound to an interior of a vehicle, a sound introduction hole formed in the sound tunnel, and a catalytic assembly mounted in the sound tunnel so as to clog the sound introduction hole, the catalytic assembly functioning to reduce high-frequency noise and to filter exhaust gas, thereby reducing high-frequency noise included in the exhaust sound transmitted to the interior of the vehicle and thereby filtering the exhaust gas so as to prevent introduction of the exhaust gas into the interior of the vehicle.

Abstract: The present invention relates to an apparatus installed in a vehicle for recovering exhaust heat. The apparatus includes: a housing having therein a heat exchanger and having a front through hole through which exhaust gas is introduced and a rear through hole through which the introduced exhaust gas is discharged; a first tube installed in the housing and having a dual tube structure; and a second tube connected to the first tube and having a dual tube structure. A coolant introduced through the second tube passes through the first tube and exchanges heat with the exhaust gas in the heat exchanger in the housing. The coolant, which has exchanged heat, is discharged to an engine through the first tube and the second tube.

Abstract: An exhaust heat recovery apparatus includes: a housing having a first exhaust passage and a second exhaust passage, an exhaust inlet fitting, and an exhaust outlet fitting; a heat exchanger disposed in the first exhaust passage; and a switching valve having a slide gate which is movable in a longitudinal direction of the housing so as to allow a flow of exhaust gases to be switched between the first exhaust passage and the second exhaust passage, wherein the first exhaust passage is parallel to the second exhaust passage, and the slide gate is movable between the first exhaust passage and the second exhaust passage.

Abstract: A structure is provided for installing a pipe fixing clamp installed in a sound absorber. A part of a curved pipe portion of an internal structural pipe of the sound absorber is cut to form an exhaust gas flow space. The pipe fixing clamp having multiple holes is connected to the exhaust gas flow space.

Abstract: The present disclosure provides a rear wheel steering (RWS) control method and system for a cargo trailer. The RWS control method may include determining a driving mode of a vehicle connected to the cargo trailer, executing an RWS control logic of the cargo trailer based on the driving mode and an input signal from the vehicle corresponding to the driving mode, and performing RWS control for the cargo trailer based on the RWS control logic.

Abstract: An exhaust sound control system for vehicles includes an exhaust valve device that controls the volume of exhaust sound by controlling the amount of exhaust gas flowing through a muffler. In a sporty driving mode, exhaust sound is permitted to be transferred to the interior of the vehicle, and in a silent driving mode, the volume of exhaust sound transferred to the interior the vehicle is minimized. The volume of exhaust sound transferred to the interior of the vehicle is varied depending on the driving mode desired by the driver. Accordingly, the sensorial quality related to sound generated while driving is improved.
