A system and method for power management of a hybrid vehicle is provided. In some implementations, a plug-in series hybrid vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG to control operation of the engine and the MG such that a state of charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during stroke and maintains an average engine power (AEP) above a threshold. In some cases, maintaining the AEP above a threshold supports emissions control of the vehicle.
提供了一种对混合动力车辆进行电力管理的系统和方法。在一些实现中,插电式串联混合动力车辆可以包括:发动机、电动机/发电机(MG)、牵引电动机、储能装置、以及控制器。该控制器被联接至发动机和MG,以控制发动机和MG的运行,使得储能装置的荷电状态(SOC)在行程期间跟踪动态参考SOC分布曲线,并且使平均发动机功率(AEP)维持在阈值之上。在一些情况下,使AEP维持在阈值之上支持车辆的排放控制。
