Power Management Strategy

In this article, a novel system configuration with multiple energy sources is proposed for a hybrid truck in order to reduce fuel consumption and overcome the drawbacks of using a single energy source. The energy-saving characteristics of the hybrid system can be displayed after analyzing its system structure and performances. In order to validate the advantages of this presented system, the dynamic models of the system components are established in a MATLAB/Simulink environment, and initial and improved power management strategies with rule-based algorithms are developed. Then, the hybrid system is simulated based on the models and control strategies over the urban dynamometer driving schedule driving cycle. The simulation results show that the fuel consumption employing the initial power management strategy is 12.49 L/100 km, and there is a significant decrease with around 13.6% based on the improved strategy. The results also verify that the better fuel economy can be achieved by the proposed multi-source system compared to the counterparts under the same operating conditions.

Optimization of gear ratio with the objectives of fuel consumption reduction and vehicle longitudinal performance improvement has been the subject of many studies for years. Finding a strategy for changing gears with specific control objectives, especially in the design of vehicles equipped with Continuously Variable Transition system (CVT), which has advantage of arbitrary selection of gear ratio, has been the aim of some recent researches. Optimal control theory has rarely been used in the previous control approaches applied to such systems due to the limitations in the use of fast computational systems. The aim of this study is to design the aforementioned gear ratio change strategy and related control rules on the basis of optimal control. A driver model is also designed for the simulation of driving cycle using MATLAB Simulink Toolbar. Results of implementing optimal control rules in vehicle longitudinal movement simulation with the aim of fuel consumption reduction are finally represented. The presented method has the remarkable advantage of considerable fuel consumption reduction in comparison to other proposed approaches for gear ratio change strategies.
