A hybrid electric vehicle includes: a dual clutch transmission having first and second sub-transmissions having respective first and second clutches and first and second synchronizers, and an electric motor rotationally coupled to the second sub-transmission for common rotation therewith; and a control system including a hybrid controller and a transmission controller with the HCP being a supervisory controller, wherein the control system is configured to execute an engine clutch start procedure using the electric motor, and wherein the procedure eliminates hard vehicle speed limits, provides smooth wheel torque during the procedure, and increases a number of transmission gears available for the procedure.

A hybrid electric vehicle (HEV) includes an internal combustion engine, an electric traction motor, a motor/generator, and a transmission. A launch control system includes a controller having one or more processors programmed to (A) operate the HEV in a vehicle launch preparation phase while the HEV is at a standstill, including (i) commanding the internal combustion engine to an engine speed launch target, (ii) performing a spark retardation on the internal combustion engine to limit wheel torque and generate an engine airflow torque reserve, and (iii) commanding zero torque to the electric traction motor; and (B) operate the HEV in a vehicle launch phase, including (i) reducing or removing the spark retardation, and (ii) commanding the electric traction motor to operate at a predetermined torque, to thereby utilize the engine airflow torque reserve in combination with the electric traction motor to provide increased vehicle acceleration.
