Research on fuel economy for HHV based on road and Traffic Information System

With the application of the information of road and traffic in a certain future predictive route provided by Board and Traffic Information System on board, and car current operating state model the HHV (hydraulic hybrid vehicle), build HHV for a prediction in the future the operation status of model route; To the accumulator loading state, for the system state variables for the second component torque decision variables, HHV equivalent fuel consumption minimum for optimization control target function, using the dynamic programming, a reverse algorithm moderate HHV predictive control mathematical model; Research the HHV torque distribution the optimal control method. This paper gives a HHV calculation example of the optimal control results.
