Abstract:

In view of that the most existing studies on eco?driving control are based on fully intelligent network connected environment, which may not be suitable for the mixed traffic scenes covering traditional human?driven vehicles (HDVs) and network connected vehicles (CVs), a hierarchical eco?driving control method for hybrid electric vehicles platoon consisting of HDVs and CVs is proposed in this paper with consideration of the operation error of drivers. The upper layer controller is designed by using stochastic model predictive control algorithm to fulfill the multi?objective optimization of the mobility, fuel economy and comfort of the platoon, while the adaptive equivalent consumption minimization strategy is adopted to design the lower layer controller for optimizing the power assignment between vehicle engine and battery. Simulations results show that the method proposed can effectively reduce the speed trajectory deviation of hybrid electric vehicles in the platoon caused by the driver operation error, with its average fuel consumption lowering by 2.82%.
