This work is focusing on the extension of the well-known equivalent consumption minimization strategy (ECMS) for analysis of new hybrid electric vehicle (HEV) concepts featuring two traction motors. Given the contribution to advanced systems engineering, the control algorithm is derived under consideration of causality and practicality. Having more than one traction motor, a two-dimensional torque-split allowing full parallel operation of the HEV powertrain is required. Furthermore, this HEV enables series operation mode, and an example of implementation is given as well. Since we define the capability of comprehensive system analysis as a major attribute of the energy management, we abstain from restricting the solution space via heuristics e.g. mode selection in advance. This gives birth to affect the control behavior only by applying constraints directly to the control problem and thus enables analysis based on the respective (sub)optimal solutions. In this paper, a brief example of implementing so-called soft constraints for reducing the number of engine starts is given. The practicality of the proposed 2D-ECMS is proven within a simulation study and control behavior is analyzed. Additionally, different effects of variable constraints and parameter settings are investigated. |
