TECHNIQUES FOR BLENDING IN MECHANICAL FRICTION BRAKES DURING DECLERATION FOR HYBRID VEHICLE WITH ELECTRIC MOTOR MECHANICALLY COUPLED TO TRANSMISSION GEARS

An electrified vehicle includes a transmission having shiftable gears, an electric motor coupled for common therewith, and a synchronizer controllable for coupling the transmission to a driveline; friction brakes; a control system including a hybrid control unit, a brake control unit and a transmission control unit, wherein the hybrid control unit functions as a supervisory controller over the transmission control unit and the brake control unit and wherein the hybrid control unit is configured to coordinate control among the transmission control unit and brake control unit to compensate for unavailability of electric motor regeneration torque during an upcoming transmission gear shift event and blend in the friction brakes to provide a continuous and smooth deceleration of the electrified vehicle during the transmission shift event.
