Embodiment Construction

[0020] figure 1 A block diagram is shown which, for the understanding of the invention, shows the main components of a device for reversing detection in an electrical control unit of a vehicle. The electrically operated unit is a window regulator of the vehicle. The window pane is raised and lowered by means of an electric drive with a stator and a rotor, wherein the rotor contains the rotor shaft 1 .

[0021] The rotor shaft 1 is connected to the sensor wheel 1a in a rotationally fixed manner. The sensing wheel has equidistant encoded segments or poles. During the rotation of the sensor wheel 1a, a pulse signal is detected by the sensor device 2 and transmitted to an evaluation unit 3 formed by microcomputing. The evaluation unit 3 increments the position value stored in the position counter 4 upon receipt of each pulse, so that the counter reading of the position counter 4 accurately describes the current position of the window pane.

Abstract

The invention relates to a method and a device for identifying a reversing operation in an electric actuating unit of a vehicle. According to said method, 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 said 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.

Description

technical field [0001] The present invention relates to a method and a device for reversing detection in an electrical control unit of a vehicle. Background technique [0002] Electrically operated units in vehicles, such as sliding sunroofs or window regulators, are equipped with positioning means. Said positioning means are necessary so that each window or sliding roof can be stopped precisely in the desired position. Furthermore, the positioning means are necessary in order to ensure legal requirements regarding anti-pinch protection. [0003] In the known positioning devices in window regulators, the first initialization is carried out within the scope of manufacture by running the window pane to its upper mechanical stop. This is detected by the control unit and used as a reference for later position counting processes. The position counting process is carried out by counting Hall sensor pulses associated with the rotation of the respective drive motors during the up...
