System and Method of Blockage Detection During an Automatic Adjustment of a Movable Vehicle Part in a Motor Vehicle

摘要

A system and method are provided for detecting blockages during an automatic adjustment of a movable vehicle part in a motor vehicle equipped with an electric motor drive and an electronic control unit. The drive current as well as the movement speed of the drive are detected by the electronic control unit. When the movement speed increases above the normal level, the control unit suppresses the detection of a blockage event if a drive current increase required for the movement speed increase cannot be ascertained.

主权项

1. A system for detecting blockages during an automatic adjustment of a movable vehicle part in a motor vehicle, comprising:
an electric motor drive configured to move the movable vehicle part in the motor vehicle; an electronic control unit in communication with the electric-motor drive, wherein
the electronic control unit detects a drive current and a movement speed of the electric motor drive, andthe electronic control unit suppresses detection of a blockage when the movement speed increases above a normal level but an associated increase of the drive current for the increased movement speed cannot be determined.
