    摘要： A system includes a turbocharged engine, sensors, and a controller. The engine includes an engine intake manifold, air intake manifold, a compressor, a first aftercooler device, a throttle that admits cooled compressed air to the engine intake manifold, and cylinders. The sensors determine engine status signals and include a first manifold pressure (MAP) sensor positioned with respect to the first aftercooler device, a second MAP sensor positioned with respect to the engine intake manifold, a mass airflow (MAF) sensor positioned in the air intake manifold, a first manifold temperature (MAT) sensor positioned in the engine intake manifold, and a second MAT sensor positioned between the first aftercooler device and the throttle. The controller executes a method to calculate a cylinder air charge using an oxygen level of post-combustion gasses and the engine status signals, and controls an operation of the engine using the calculated air charge via engine control signals.

    摘要： A computer for an energy management system of an electric vehicle includes a processor. The computer further includes a memory including instructions such that the processor is programmed to determine a value function V based on a plurality of actions U in a plurality of states S. The processor is further programmed to select an action associated with a highest reward value at a current state S. The action U is an HVAC subsystem variable. The state S is a traction power drawn from a rechargeable energy storage system (RESS) to operate a traction subsystem, a base power input drawn from the RESS to operate an HVAC subsystem, a nominal reference cabin heat input set-point determined by the local HVAC processor, an acceleration of the electric vehicle, a current vehicle speed, an average vehicle speed, and a calibrated average vehicle speed estimate.

    摘要： A system and method are provided for operating a powertrain control system. The method includes receiving data measured from a plurality of sensors, the measured data relating to distance dependent speed values, and receiving information from one or more vehicle modules, the vehicle module information relating to distance independent speed values. The method further includes building a speed trajectory profile for a horizon window that includes a plurality of speed change regions represented by at least some distance dependent speed values or at least some distance independent speed values, and creating a synthesized speed profile for the horizon window by processing the speed trajectory profile. The synthesized speed profile optimizes efficiency of the powertrain control system at each of the plurality of speed change regions.

    摘要： Presented are intelligent vehicle systems and control logic for predictive route planning and adaptive control, methods for manufacturing/operating such systems, and motor vehicles with real-time eco-routing and automated driving capabilities. A method for controlling operation of a vehicle includes determining vehicle origin and destination information, and identifying candidate routes for traversing from the origin to the destination. Road-level data, including speed and topology data, is received for each candidate route. Total energy uses are estimated for propelling the vehicle from the origin to the destination across each of the candidate routes. This estimating includes evaluating respective road-level data of each candidate route against a memory-stored table that correlates energy consumption to speed, turn angle, and/or gradient. A resident vehicle controller commands a resident vehicle subsystem to execute a control operation based on one or more of the estimated total energy uses corresponding to one or more of the candidate routes.

    摘要： The method can control a powertrain in order to maintain the charge temperature at a desired value regardless of exhaust manifold pressure or altitude. The method includes the following steps: (a) receiving a torque request; (b) determining a desired air charge based, a least in part, on the torque request; (c) determining an actual air charge based, at least in part, on input signals from a manifold absolute pressure (MAP) sensor and a mass airflow (MAF) sensor; (d) adjusting an intake valve timing of the intake valve such that the actual air charge is equal to a desired air charge, and (e) adjusting throttle position and actuator positions of boosting devices such that the actual intake manifold pressure is equal to the desired intake manifold pressure.
