HEV ENGINE START VIBRATION REDUCTION SYSTEM
20190031178 · 2019-01-31 ·

A hybrid electric power-split vehicle, equipped with a continuously variable transmission coupling an electric motor/generator (EM) with a combustion engine (CE), includes systems and methods that reduce possible resonant noise and vibration during CE startup, by improved EM control, to generate compensating EM torque to counter act such possible resonant noise and vibration. The systems and methods include predetermined baseline CE operating condition (OC) cranking torque profiles stored as OC grids (SOCGs). A start profile is generated from selected cranking torque SOCGs, and also from selected historical start OCGs (HOCGs) of prior engine and/or CE starts, which include prior start noise and vibration metrics along with prior start OCs and related parameters. The start profile is calibrated using a blend factor that is generated from comparisons of SOCGs, and utilized to generate a feed-forward torque signal that adjusts EM torque to reduce the startup noise and vibration resonances.

Power transmission device for vehicle

A tolerance ring is interposed between an output side rotary shaft and a rotor shaft. For this reason, even in a case where a backlash formed in a spline fitting portion between the output side rotary shaft and the rotor shaft is not eliminated, the rotary shafts of both of the output side rotary shaft and the rotor shaft are held by the tolerance ring without a backlash, and rattling noise can be suppressed. An oil supply groove for supplying a lubricant between an annular portion of the tolerance ring and the output side rotary shaft is provided inside an annular groove formed in the output side rotary shaft. With this, it is possible to suppress degradation of the durability of the tolerance ring without performing special processing on the tolerance ring.

Front vehicle-body structure of vehicle

A front vehicle-body structure of a vehicle comprises a hinge pillar, an apron reinforcement, a suspension housing, a side sill, and a connecting member which connects the apron reinforcement to the hinge pillar in a brace shape and connecting the apron reinforcement to a front portion of the side sill. The connecting member includes first and second bending portions which are positioned between a rear face portion and a side face portion and between a forward flange and the side face portion, respectively, and the apron reinforcement and the side sill are continuous to each other via at least one of the first and second bending portions.

AIR PASSAGE TYPE WHEEL DEFLECTOR AND VEHICLE HAVING THE SAME

An air passage type wheel deflector applied to a vehicle may include a deflector body 10 fastened to the floor panel by screws 40 and mounted at the rear wheel 120 side, an air duct 20 forming an air passage 20-1 for forcing the air introduced externally to flow downward and discharge in a state of being covered by the deflector body 10 coupled to the air duct, and a plurality of ribs 30 disposed in the deflector body 10 at a certain rib spacing and positioned in the space of the air passage 20-1 so that robustness against strike by chipping is maintained and at the same time aerodynamic performance is improved resulting from improvement of the kick-up function by the air passage 20-1.

Foot-operated parking brake operation device
10160425 · 2018-12-25 · ·

A solution to reduce the ratcheting sound that occurs at the start of braking when an operation pedal is operated by foot. Because a mounting seat as a flat part and base plate are provided between a ratchet member and support axial center S of an operation pedal, there is a possibility that the ratchet member's vibration will propagate to the adjacent mounting seat and base plate, amplifying the ratchet sound. However, the adjacent mounting seat and base plate are provided with beads, having cross-sections that bend convexly in a direction substantially orthogonal to the vibration waveform of the ratchet sound produced by a pole coming into contact with serrations when the mounting seat and base plate maintain a flat plate shape; i.e., in a circumferential direction about support axial center S. Therefore, rigidity against the vibration is increased, propagation of vibration is minimized, and ratchet sound is effectively reduced.

DRAIN PLUG MASS DAMPER

A truck bed of a vehicle includes a sheet metal panel defining a drain opening, a mass damper plug disposed within the opening and including a mass casting having a predefined mass configured to tune a frequency of a sound wave of the panel and plug into a predefined range, and defining bolt threads, and a bolt engaged with the bolt threads and configured to secure the plug with the panel.

WEBBING TAKE-UP DEVICE

A webbing take-up device includes a spool that is rotated in a take-up direction to take up webbing worn by an occupant and that is rotated in a pull-out direction by the webbing being pulled out, and a frame that rotatably supports the spool. The frame includes a fixed stay portion that is fixed to a vehicle body, and a rotation stop stay portion that is disposed spaced apart from the vehicle body and that by being engaged with the vehicle body is restricted from rotational displacement relative to the fixed stay portion.
