基于联合仿真的纯电动客车制动控制策略对比分析与优化

Comparative Analysis of Braking Control Strategies for Electric Bus

纯电动客车的制动控制策略对其续航里程有着重要影响。本文针对串联式和并联式制动两种不同的控制策略,使用Matlab/Simulink与AVL Cruise进行联合仿真,通过对比分析相同工况下的仿真结果,确定串联式制动控制策略更优。接着分别采用实际公交路谱与等速路谱,并在并联式控制策略中引入电机扭矩map图,将仿真结果与监控平台的数据对比,进一步验证了模型的准确性。本文为纯电动客车制动策略选择、优化及验证提供可靠的参考依据。

The braking control strategy of electric bus has an important impact on its range.Aiming at the two different braking control strategies of series and parallel,this paper uses Matlab/Simulink and AVL cruise for joint simulation.By comparing and analyzing the simulation results under the same working conditions,it is determined that the series braking control strategy is better.Then,the actual bus spectrum and constant speed spectrum are used,and the motor torque map is introduced into the control strategy.The simulation results are compared with the data of the monitoring platform to further verify the accuracy of the model.This paper provides a reliable reference for the selection,optimization and verification of braking strategy of electric bus.
