Abstract: This paper presents a multi-mode transmission (MMT) for a hybrid electric vehicle (HEV) using a
single electric machine (EM) and validates its performance. The MMT uses two planetary gear sets and four
clutches to combine an engine and an EM with the vehicle, with the EM operated as a motor or a generator.
This HEV realizes five power flow modes, which are developed into sixteen operation modes, including various
driving, braking, and charging while parking modes. Fuel economy simulations of the vehicle were performed
in Chinese General Driving Cycle, Japan Urban and Highway Cycle, New Europe Driving Cycle, and Federal
Test Procedure 72, respectively. Comparable simulations were obtained with a benchmark vehicle which has a
planetary gear set, two EMs and no clutch. The results indicate the application potential of the proposed single
EM HEV, as the proposed HEV does not use extra electric machines and extra power electronics.

Key words: hybrid electric vehicle (HEV), single electric machine, multi-mode transmission, planetary gear set
