Automatic door latching system

摘要

Herein disclosed is an automatic door latching system for a motor vehicle having a vehicle body and a door. The automatic door latching system comprises a door lock device carried by the door to move therewith, the lock device having a latch plate which is pivotal to assume a full- open position wherein the latch plate releases a striker secured to the vehicle body, a half-latch position wherein the latch plate is halfly engaged with the striker and a full-latch position wherein the latch plate is fully engaged with the striker; a driver lever integrally connected to the latch plate to move therewith; a closing lever which is pivotal to assume a rest position and an operative position, the closing lever pushing the driven lever in a direction to cause the latch plate to pivot from the half-latch position to the full- latch position when pivoting from the rest position toward the operative position; an electric drive means mounted to the door to drive the closing lever when energized; a half-latch detecting means for detecting the half-latch condition of the latch plate; a full-latch detecting means for detecting the full-latch condition of the latch plate; a rest position detecting means for detecting the closing lever being at the rest position; and a first control unit mounted to the door for controlling operation of said drive means in accordance with information signals issued by said half- latch, full-latch and rest position detecting means.
