A trunk latch module for a vehicle may include a base plate, a first locking groove for insertion of a striker into the first locking groove, a main gear rotatably combined with the base plate at a position above the first locking groove, the main gear being supplied with power of a motor, a claw rotatably combined with the base plate, with a second locking groove provided at a first end of the claw, and with a stop protrusion provided on an outer surface of a second end of the claw, a link assembly combined with the main gear, the link assembly transmitting power to the claw by operating in conjunction with rotation of the main gear, a claw-locking assembly locking or releasing the claw by using power transmitted from the link assembly, and a guide lever guiding rotation directions of the link assembly and the claw-locking assembly.

A mobile body moving device includes: a mobile body; an engaged portion; a lock mechanism including an engaging portion, a driving section, and a position detection section; a control section calculating a reference electrical quantity by multiplying time taken for movement of the engaging portion from a movement start position to a predetermined position by an initial voltage for the movement; and a voltage detection section When determining that the position detection section is abnormal, the control section calculates a necessary driving time from the reference electrical quantity and a movement initial voltage for the movement from the movement start position during the movement, and drives the driving section only for the necessary driving time. Thereby, it is possible to perform control such that the engaging portion of the lock mechanism driven by the driving section is positioned in the predetermined position even when a voltage changes.

A wireless-based system is provided for opening the hood of a motor vehicle. That wireless-based system includes a wireless latch release actuator. Further, the wireless-based system also includes a controller. The controller is configured to release a secondary hood latch when (a) the wireless latch release actuator is activated, (b) a primary hood latch has already been released and (c) a motor vehicle wheel is stationary whereby the hood may be opened. A related hood opening method is also disclosed.

A tailgate opening/closing device has a simplified tailgate opening/closing structure, reduced manufacturing cost, reduced weight, and improved quality. The device includes a release gear configured to be rotated forwards and backwards by a rotational force from a motor, a cinching gear engaged with the release gear, a linkage mechanism configured to receive force from the cinching gear to rotate toward a claw, the claw being caught by the linkage mechanism to rotate together therewith so as to be engaged with a striker, and a pawl unit configured to be caught by the claw in the state in which the claw is engaged with the striker so as to restrict rotation of the claw and configured to allow rotation of the claw in a release operation direction only when the release gear rotates in the release operation direction.

The present invention aims to reduce the operation noise of a latch device for a vehicle trunk lid when the lid is opened. A latch device for a vehicle trunk lid includes: latch 16 that is engaged with a striker; ratchet 18 that is engaged with latch 16; opening lever 43 that causes ratchet 18 to rotate in a direction in which ratchet 18 is disengaged from latch 16; output member 39 that rotates opening lever 43 in the release direction. Opening lever 43 is rotatable between an unblocked position where it is rotatable in the release direction and a blocked position where it is prevented from rotating in the release direction by colliding with the output member. When driven and rotated, output member 39 abuts against opening lever 43 that is in the unblocked position and rotates opening lever 43 in the release direction to the blocked position, and opening lever 43 is further rotated a predetermined angle by colliding with output member 39 in the blocked position.

A bumper for a closure, such as a tailgate, acts between the tailgate and a frame to bias a striker in to engagement with a latch. The bumper is moved to a retracted position during closing to reduce the force needed to close the tailgate. After latching, the bumper is conditioned to an extended position to assert the bias between the tailgate and frame.
