A Study on the Energy Management Strategy Based on the Accuracy of Speed Profile of Hybrid Electric Vehicle

The energy management control strategy of the vehicle has a great influence on the improvement of the fuel efficiency of the vehicle. DP(Dynamic Programming) is used as an optimization theory in energy management control strategy. DP is used to optimize fuel consumption of the vehicle based on driving cycle information and rule-based control strategy. In this paper, we propose a new energy management control strategy and its significance is to verify sensitivity of the information of the driving cycle predicted according to the accuracy, and what level of information should be provided for securing reliability.
