Abstract:

The control objective for Extended Range Electric Vehicle (EREV) is to control battery State of Charge (SOC) to reach the lower bound as the vehicle arriving at charging station. First, the minimum fuel consumption and SOC varying along target curve were added in cost-function, then, Dynamic Programming (DP) algorithm was adopted to solve the optimization problem. To achieve real-time control performance, a neural network framework was applied to train the optimal results and generate control model. Simulation results show that the generated model has better learning performance that the difference error is within 3%. Since the control model is only fit for special driving cycle and driving distance, an adaptive energy management controller was proposed. It consists driving pattern recognition module, control model library and control model selection module, etc. Hardware-in-Loop test was conducted to validate the controller performance. The results show that the proposed controller can control battery SOC just dropped to lower bound at the end of driving cycle, and it improves fuel economy for 9.2% compared to CD/CS algorithm under HWFET driving cycle.

Key words: vehicle engineering, extended range electric vehicle, dynamic programming, neural network, energy management strategy
