Abstract: A method for selecting an engine operating point in a multi-mode powertrain system includes monitoring a desired axle torque based on an operator torque request and vehicle speed. For each available combustion mode of the diesel engine, engine torque and speed ranges are received and a plurality of fuel losses and a plurality of emissions losses are retrieved, each fuel and emissions loss corresponding to respective ones of a plurality of engine operating points within the engine torque and speed ranges. The respective fuel and emissions losses are compared at each of a plurality of potential engine operating points within the engine torque and speed ranges of the available combustion modes. A desired engine operating point within one of the available combustion modes is selected that corresponds to one of the potential engine operating points having a lowest power loss based on the compared respective fuel and emissions losses.
Abstract translation: 一种用于在多模动力系统系统中选择发动机工作点的方法包括基于操作者扭矩请求和车辆速度来监测期望的轴转矩。 对于柴油发动机的每个可用燃烧模式，接收发动机扭矩和速度范围，并且检索多个燃料损失和多个排放损失，每个燃料和排放损失对应于内燃机的多个发动机工作点中的各个 发动机扭矩和转速范围。 在可用燃烧模式的发动机扭矩和速度范围内的多个潜在发动机工作点中的每一个处比较各自的燃料和排放损失。 基于所比较的相应的燃料和排放损失，选择对应于具有最低功率损耗的潜在的发动机工作点之一的可用燃烧模式之一内的期望的发动机工作点。
