Patent number: 8754600Abstract: In a method and a device for identifying a reversing operation in an electric actuating unit of a vehicle, once a trapped object is detected, the rotational direction of the electromotive drive is commutated. Sequential pulse interval counter values, derived from a sensor system or data derived from the values is or are written to a ring buffer store and compared with pre-defined reference data patterns. If a match is found, the counter reading of the position counter is corrected in accordance with the pre-defined reference data pattern. This ensures that the counter reading of the position counter is correct even after a reversing operation.Type: GrantFiled: September 11, 2008Date of Patent: June 17, 2014Assignee: Continental Automotive GmbHInventors: Stefan Holzmann, Wolfgang Köllner, Roman Moraweg
