CONTROL DEVICE FOR AUTOMATIC TRANSMISSION Russian patent published in 2018 - IPC B60W10/10 B60W10/02 B60W10/08 B60W10/115 

FIELD: transportation.

SUBSTANCE: device comprises: a friction engagement element, an engagement start identification means, an identification prohibition means for prohibiting the identification by the engagement start identification means. The engagement start identification means is to identify that the friction engagement element has started the engagement. In case the electric motor load is increased by a predefined value, while controlling the number of revolutions, in which the number of the automatic transmission input shaft revolutions is controlled up to a predefined target number of revolutions, and when the motion range is selected, and the friction engagement element in the disengagement state is engaged. The identification prohibition means for prohibiting the identification by the engagement start identification means before identifying that the friction engagement element has started the engagement. In the event that a switching from the HEV-mode occurs, in which the driving forces from the engine and the electric motor are input to the input shaft, into the EV-mode, in which only the driving force of the electric motor is input to the input shaft.

EFFECT: error-free identification of the electric motor load variation, resulting from switching from the HEV-mode to the EV-mode.
