By analyzing the parallel hybrid electric vehicle mode, the optimization of output power to fuel engine and electric motor is discussed. The fuzzy logical rules are proposed by fuzzy control theory. According to the system required power and battery SOC, the engine output power and the motor output power are optimized. The results show that the optimization method based on fuzzy logical can effectively reduces fuel consumption and can well control the battery SOC changes.

The Power Synthesizer of Parallel Hybrid Electric Vehicle (PHEV) has been the research object. It is composed of the differential gear train, in which its power distribution and sensitivity has been analyzed as main problems. The transmission ratio, torque and power distribution have been analyzed about the gear train. Whatever its structure is, if only the value of structure parameter K is same, then the corresponding relative kinematics relation and mechanics relation of the basic components are same absolutely. The calculation of power distribution among basic components has been introduced. The sensitivity has direct influence to the mobile performance of vehicle, so the angular speed response for output components to input components has been analyzed, and the connecting mode between engine or motor and differential gear train has been bought forward. The analytical results can be helpful for the parameters’ design of kinematics and dynamics of the vehicle, and for the vehicle’s control.

According to the Parallel Hybrid Electric Vehicle (PHEV) demands on powertrain systems, the dynamic models of PHEV are built in this paper. Base on the analysis of dynamical characteristics of both internal combustion engine (ICE) and electric machine (EM), the dynamic ability and fuel economy performance of PHEV is presented. The paper focuses on the parametric design of powertrain on vehicle performance, which provided the theoretical foundation for PHEV design. The paper also puts forward the control strategy of PHEV during the operating modes switching, which aims to solve the problem of the power distribution between the ICE and electric motor, which can effectively resolve process control problems of the complex PHEV system. By employing the dynamic model and performing MATLAB simulation, the results of simulation are given, which demonstrate that the PHEV improve performance well.

It is necessary for Parallel Hybrid Electric Vehicle (PHEV) to distribute energy between engine and motor and to control state-switch during work. Aimed at keeping the total torque unchanging under state-switch, the dynamic torque control algorithm is put forward, which can be expressed as motor torque compensation for engine after torque pre-distribution, engine speed regulation and dynamic engine torque estimation. Taking Matlab as the platform, the vehicle control simulation model is built, based on which the fundamental control algorithm is verified by simulation testing. The results demonstrate that the dynamic control algorithm can effectively dampen torque fluctuations and ensures power transfer smoothly under various state-switches.
