Abstract:By analyzing the structure， working principle， and operation flow of the traditional synchronous gravel sealer vehicle， a series hybrid power system structure of the synchronous gravel sealer vehicle was proposed. Based on the basic parameters and power performance of a certain type of synchronous gravel sealer vehicle index， the parameter matching research and selection of the main power components in the hybrid power system of the synchronous gravel sealer vehicle were carried out. By combining energy flow characteristics and the transition and operation of the four working modes of the hybrid synchronous gravel sealer vehicle energy demand under working conditions， system energy management was researched， and energy management strategy between extended-range vehicle engine and auxiliary energy source were formulated. The Cruise simulation software was used to build the hybrid power system simulation model of the synchronous gravel sealer， and the proposed energy management strategy was imported into the Cruise simulation platform. Based on the combined simulation of Cruise and MATLAB， the dynamic performance of the hybrid synchronous gravel sealer was studied. Simulation results show that the parameters of each part of the hybrid synchronous gravel seal vehicle can be matched well to meet the working requirements. The engine can always work in the optimal range with small fluctuations. The fuel-saving rate of the hybrid synchronous gravel seal vehicle is 24.7%， and the energy recovery rate is 20.34%. Therefore， fuel economy performance has been greatly improved.
