Four concepts of strong hybridization powertrains on all-wheel-drive sport utility vehicles (SUV) are presented. These concepts enable conversion of conventional powertrains into strong hybrid powertrains with minimal tear-up to the existing architecture. The first concept incorporates an electric machine attached to the output side of a conventional transmission. The second concept is a strong input power-assist system, where the motor is packaged between the torque converter and the transmission. The third concept is similar to the second one, but the torque converter is replaced by a starting clutch. The fourth concept is a compound-input, power-split, electric-variable transmission (EVT). These concepts provide extensive hybrid functionality, such as motor-only drive, launch assist, and energy recuperation. Simulation results indicate that proposed strong hybrid concepts can result in fuel economy gains of 19-26 per cent over conventional powertrains.
