摘要
以整车燃油经济性和排放性能为控制目标,提出一种模糊逻辑转矩分配策略,在MATLAB/Simulink中建立整车仿真模型,并选用国家标准工况进行整车性能仿真研究。仿真结果表明,所建模型可实现需求转矩在发动机与集成起动发电机(ISG)之间动态协调分配,达到系统能量流的多样性,从而提高了整车的燃油经济性和排放性。
Aiming at fuel economy and emission performance as major control objects,a fuzzy-logical torque distribution strategy was proposed.A vehicle simulation model was built to analysis the performance of the vehicle under the national standard drive cycle by MATLAB/Simulink software.The results showed that the model built could achieve the required torque dynamic coordinative distribution,raise the various of the energy flow in the vehicle,finally it lowed the flue consumption and exhaustion.
