FIELD: motor vehicle industry.

SUBSTANCE: invention relates to a door check of a vehicle, namely, to an automobile door system, a smooth door check and to a method for limiting a door opening. Car door system includes a hinge supporting the door and a door check module connected to the vehicle or to the door by means of a linkage. Output shaft is connected to the linkage and is rotatably connected to the housing of the door check module. Output shaft generates torque to limit the opening of the door in the required position. Shaft rotation is detected by a sensor that produces a signal in response to the rotation of the shaft. Brake assembly includes a shaft-shaped element operatively connected to the output shaft. Brake assembly has a normally closed position in which the shaft-shaped element in the door opening restriction mode is short-circuited to the frame, and an open position corresponding to the door closing or opening mode. In response to this signal, the brake assembly is moved from the normally closed position to the open position.
