摘要: |
With the help of traffic information of the connected environment, an energy management strategy (EMS) is proposed based
on preceding vehicle speed prediction, host vehicle speed planning, and dynamic programming (DP) with PI correction to
improve the fuel economy of connected hybrid electric vehicles (HEVs). A conditional linear Gaussian (CLG) model for
estimating the future speed of the preceding vehicle is established and trained by utilizing historical data. Based on the
predicted information of the preceding vehicle and traffic light status, the speed curve of the host vehicle can ensure that the
vehicle follows safety and complies with traffic rules simultaneously as planned. The real-time power allocation is composed
of offline optimization results of DP and the real-time PI correction items according to the actual operation of the engine.
The effectiveness of the control strategy is verified by the simulation system of HEVs in the interconnected environment
established by E-COSM 2021 on the MATLAB/Simulink and CarMaker platforms. |
