A control device of an active direction.

The invention relates to a device (1) for controlling an active direction. This device comprises a differential (2) for driving which is interposed between a flywheel (3) and means (4) for steering control. This differential (2) also receives at a first input (8) against a control steering provided by a motor (9) for correcting curve. It is characterized in that the flywheel (3) is connected to a second input (15) of the differential (2) by a non-return means (16) for preventing a stress differential lift (2) towards the steering wheel (3).
