| 摘 要： | 根据并联混合动力汽车的特点,提出了以保证车辆动力性为前提的混合动力汽车最佳经济性三参数换档规律。升档规律和驱动模式的降档规律采用发动机转矩、电机转矩和车速作为换档参数。制动模式的降档规律采用电机制动转矩、机械制动转矩和车速作为换档参数。计算表明,与原有的沿袭传统汽车的两参数换档规律相比,混合动力汽车最佳经济性三参数换档规律在驱动模式下可以降低油耗,在制动模式下可以显著增加制动能量回收的比例。

| Abstract: | According to the characteristics of parallel hybrid electric vehicle,a three-parameter economy shift algorithm for hybrid electric vehicle was proposed without degrading the vehicle dynamic performance.In the upshift algorithm and driving mode downshift algorithm,engine torque,motor torque and vehicle speed were used as the shift parameters.In the braking mode downshift algorithm,motor braking torque,mechanical braking torque and vehicle speed were used as the shift parameters.Calculation results show that,... |
