Motorbetriebenes Fahrzeugtür-Schließsystem

摘要

A powered vehicle door closing system for producing an auto-closing action to automatically move a latch member from a half-latched position to a fully-latched position, comprises a reversible motor mechanically linked through a linkage to the latch member for powering a final, low-displacement/high-force movement of a vehicle door, a half-latch detection switch such as a limit switch, and a controller for controlling the motor. The controller comprises a full-latch detection section for detecting the fully-latched position of the latch member and a stand-by position detection section for detecting the stand-by position of the linkage. To detect the fully-latched position and the stand-by position, the full-latch detection section and the stand-by position detection section respectively utilize changes in load imparted to the motor.
