The invention relates to a system and a method for improving vehicle driveline operation. Provided are methods and systems for operating a hybrid driveline. The hybrid driveline includes an engine andan electric machine are presented. In one non-limiting example, the engine and electric machine are operated according to a solution of a Hamiltonian that includes a first co-state and a second co-state, an engine fuel flow parameter, a rate of change of battery state of charge parameter, and an emissions flow rate parameter. 本申请涉及用于改进车辆传动系运转的系统和方法。提出用于运转混合动力传动系的方法和系统，该混合动力传动系包括发动机和电机。在种非限制性示例中，根据汉密尔顿函数的解运转发动机和电机，所述汉密尔顿函数包括第协态和第二协态、发动机燃料流动参数、电池荷电状态的变化速率参数以及排放物流动速率参数。
