This paper presents the method of designing the plug-in hybrid powertram with planetary transmission. The simulation results which are based on simulation in MATLAB/SMULINK environment show that Compact Hybrid Planetary Transmission Drive (CHPTD) is a suitable configuration for plug-in hybrid application. The advantage of planetary transmission is obtained by proper design and control of a new electromagnetic clutch-brake system. Control strategy influences the performance of hybrid powertram significantly. With the proper control strategy, the plug-in hybrid powertram could achieve good performance on fuel consumption and battery state of charge (SOC) management. With optimized gear ratio and control strategy, the implementation of 4-speed gearbox increases the fuel efficiency in different driving conditions. According to the simulation results, the fuel consumption of hybrid powertram with 4-speed gearbox is decreased by 14 8% compared to that without gearbox. Generally, with equipping 4-speed gearbox, it also increases energy efficiency of regenerative braking by 8 8%. Anyway, additional speeds of gearbox can allow plug-in hybrid electric vehicle (PHEV/EV) to pass some steeps which would be not possible for constant ratio reducer applied if the maximal vehicle speed has to be the same.
