FIELD: machine building.
SUBSTANCE: invention relates to vehicle transmissions. Vehicle transmission control device comprises controller performing control with feedback on rotation frequency relative to electric motor connected with engaging coupling during request for gear shifting. Also, the controller outputs the engagement instruction to the engaging clutch when the frequency of differential rotation of the clutch falls within the limits of the rotation speed range when determining synchronization, which is set equal to the specified differential rotation frequency, which is not zero rotation frequency. Control with feedback outputs feedback torque to bring the actual motor rpm to the target frequency corresponding to the frequency when determining synchronization. After performing feedback control, controller reduces efficiency of control with feedback by rotation frequency to start engagement of engaging coupling compared to moment before engagement.
EFFECT: increased ride comfort.
