Research on Parameters Matching Design Method for Planetary Hybrid Logistics Vehicle

Abstract This article applies planetary hybrid system to logistics vehicles, and parameter matching of key components for vehicle power source. In the matching of planetary rows, a method based on the optimal solution of the eigenvalues of the transmission system efficiency is used to optimize the selection of eigenvalues. Considering the full use of engine dynamics, the two motors are matched in the case of using the engine’s external characteristic strategy, and they are solved under the limit conditions and C-WTVC operating conditions respectively. When energy matching is performed on the super capacitor, the kinematics segmentation is performed on the operating conditions to analyze the energy variation in each segment. Finally, a logistics vehicle model is established in Cruise to simulate the dynamics and economy to prove the reasonable matching method.
