AUTOMATIC DOOR LATCHING SYSTEM

摘要

Herein disclosed is an automatic door latching system for a motor vehicle having a vehicle body (2) and a door (1). The automatic door latching system comprises a door lock device (38) carried by said 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 driven 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 said driven lever in a direction to cause said latch plate to pivot from the half-latch position to the full-latch position when pivoting from the rest position toward said operative position; an electric drive means (21) mounted to the door to drive the closing lever when energized; a half-latch detecting means for detecting the half-latch condition of said latch plate; a full-latch detecting means for detecting the full-latch condition of said 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.
