Control circuit for a drive motor of a movable element of a motor vehicle

Abstract

Abstract 1. A circuit controlling the driving motor of an opening panel of a motor vehicle, such as a window glass or the openable roof, comprising means (4, 7D, 7M, 9D, 9M, 12D, 12M, 5, 19D, 19M, 24D, 24M) for supplying power to the motor in both directions of operation by means of a selector (2) having two sections (3D, 3M) respectively pertaining to these two directions means (37, 40, 44, 49) for generating a signal representing at the end of the closing travel of the panel, the engagement of the latter in a sealing element, and means (32M, 27M, 10M, 9M) which in response to this signal, are capable of stopping the operation of the motor in the closing direction, characterised in that it further comprises means (60, 61, 62, 63, 24M) which following on the delivery of said signal, ensure the supply of power to the motor (I) in this same direction during a predetermined brief period of time by inhibiting the action of said stop means (32M, 27M, 10M, 9M).
