Series Hybrid Electric Bus Design And Simulation Research

Hybrid Electric Vehicle (Hybrid Electric Vehicle, or HEV) is the current solve the energy shortage and environmental pollution problems of practical technology. Urban public traffic congestion, bus stops, walking, slow traffic, pollution extremely serious. City Buses are generally fixed road, fixed-time operation, the total length of the daily operation of most of the 150 km-200km around. In such circumstances, the traditional internal combustion engine vehicle fuel consumption and emissions are poor, and hybrid system is to play to their strengths.This article carries on the re-equipping based on some traditional fuel oil public transportation, and unifies the present domestic and foreign mix power automobile the development survey, in view of the city mass transit and the city passenger train movement characteristic, carries on the parameter choice to the tandem Hybrid Electric transportation various key component to match and to complete the general arrangement;Establishes the entire vehicle travel dynamics, the electric motor, the wheel, the accumulator cell as well as the entire vehicle simulation model; Conducts the thorough research to the tandem Hybrid Electric public transportation control strategy; To mixes the power public transportation the power performance and the efficiency carries on the simulation analysis. And in this foundation, carries on the comparison to the entire vehicle power performance test result and the simulation result, has confirmed the simulation model rationality as well as the system design feasibility.
