Power-closing motor-vehicle door latch

A motor-vehicle door latch comprising:

• a pair of engageable parts one of which is movable between a pair of end positions and through an intermediate position between the end positions;
• a pair of end-position sensors and an intermediate position sensor operable when the parts reach the respective positions for generating respective outputs;
• drive means engaging at least one of the parts for displacing the parts from one end position through the intermediate position into the other end position;
• and
• control means connected to the drive means and to the sensors for operating the drive means to
• displace the parts from the one end position to the intermediate position only when travel of the parts from the one end position to the intermediate position takes place in less than a predetermined first time and
• displace the parts from the intermediate position to the other end position only when travel of the parts from the intermediate position to the other end position takes place in less than a predetermined second time different from the first time.
