摘要
以某混联式混合动力汽车为对象,研究了3种驱动模式下车内噪声的分布规律及特征。分析了混联式HEV结构布置形式及整车控制策略对HEV车内噪声的影响机理,得到了多驱动模式下车内噪声分布规律与HEV控制策略的相互关系。对比分析了3种驱动模式下HEV车内噪声分布特征与传统内燃机轿车及纯电动车车内噪声分布规律的异同之处,发现电动机产生的电磁噪声对HEV车内噪声影响较大。
We select a series-parallel HEV as research object to study the interior noise distribution rule and characteristic under 3 different driving modes. The mechanism how the series-parallel HEV structural layout pattern and vehicle control strategy affect HEV interior noise is analyzed, and the correlation between interior noise distribution rule and HEV control strategy in multiple driving modes is obtained. In addition, the similarities and differences of interior noise distribution characteristic between HEV, conventional ICE car and BEV in three drive modes are analyzed, and it reveals that electromagnetic noise generated from E-motor affects HEV interior noise greatly.
