Abstract: Mode transitions are significant events in the operation of a hybrid electric vehicle with dual clutch transmission (HDCT). Owing to the friction induced discontinuity of the clutch torque, seamless transition is difficult to achieve. First, this paper presents mathematical equations for the nonlinear system. Then it presents the linearised model for the proposed system. The control objective of the model reference adaptive controller (MRAC) considered in this paper is to minimise fuel consumption and reduce torque interruption in a hybrid electric vehicle (HEV). The simulation and experimental results from an HDCT demonstrate that the MRAC achieves reduced torque interruption and less vehicle jerk compared to the conventional operation method, in addition to smooth and fast transition from pure electrical driving to hybrid driving.

Keywords: HEV; hybrid electric vehicle; HDCT; hybrid electric vehicle with dual clutch transmission; mode transition; MRAC; model reference adaptive control.
