Abstract:

This article presents a real-time torque distribution strategy for a single-shaft, plug-in hybrid electric vehicle (PHEV) and investigated the effect of multiple operating parameters by using three working conditions, namely, steady operating conditions, acceleration operating conditions, and brake operating conditions. The corresponding experiments were performed according to the earlier discussed three working conditions. The main conclusions of this study are given as follows: (1) Under steady operating conditions, the engine no longer offers torque to the motor for charging when the pedal degree is higher than 60%. (2) Under acceleration conditions, the engine startup is sensitive to the state of charge (SOC) decrement, maximum of 1%, and this decrement increases with an increase in the initial SOC. (3) Under brake operating conditions, the initial SOC may have a significant influence on the variation stability of motor torque, especially when the braking intensity is less than 0.1.
