    Abstract: 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.

    Abstract: Vehicles and related systems and methods are provided for managing energy consumption by resources associated with the vehicle. A power management service receives an abstract request for a resource from a software entity, obtains current status information for the vehicle from one or more systems associated with the vehicle, determines whether the requested activation of the resource associated with the abstract resource abstract request is permitted based at least in part on the current status information and a usage profile associated with the abstract resource request, and in response to determining the requested activation of the resource is permitted, the power management service automatically provides a concrete activation request to the resource.

    Abstract: Operating a subject vehicle equipped with an adaptive cruise control system includes setting initial states for control parameters, including setting a desired vehicle speed and determining a desired following gap range, wherein the desired following gap range is associated with a lead vehicle. Operation is controlled via the adaptive cruise control system based upon the initial states for the control parameters. Operation also includes monitoring for presence of the lead vehicle. Upon detecting presence of the lead vehicle, an actual following gap is determined between the subject vehicle and the lead vehicle, and the initial states of the control parameters associated with the adaptive cruise control system are adjusted based upon the actual following gap between the subject vehicle and the lead vehicle, and the desired following gap range. Operation is controlled via the adaptive cruise control system based upon the adjusted initial states of the control parameters.

    Abstract: A method of controlling a vehicle includes determining a current operating situation of the vehicle, and identifying a subset of a plurality of sensors of the vehicle needed to provide data to enable a vehicle control function for the current operating situation of the vehicle. A remainder of the plurality of sensors is disengaged to reduce electric energy usage by the vehicle while the vehicle is operating in the current operating situation of the vehicle. A sampling rate for the selected subset of sensors may be reduced to further reduce energy usage of the vehicle. Additionally, an energy reduction processing strategy may be implemented to reduce a processor frequency or a voltage of a computing device used to provide the vehicle control function to further reduce energy usage of the vehicle.

    Abstract: Methods of charging a vehicle battery pack are disclosed. Example methods may include determining a voltage imbalance between at least two parallel strings of a battery pack exceeds a threshold magnitude. Methods may further include electrically reducing the voltage imbalance between the at least two parallel strings using a series circuit including a first group of one or more of the battery cells of a first one of the parallel strings, and reconnecting the parallel strings in an electrical circuit in parallel to each other, in which configuration the strings of the battery pack may supply power to the vehicle.

    Abstract: A host vehicle includes an internal combustion engine, a turbocharger in fluid communication with the internal combustion engine, a communication system configured to transmit and receive a traffic-related message, and a controller in communication with the turbocharger and the communication system. The controller is programmed to: receive the traffic-related message via the communication system; and command the internal combustion engine to increase a power output to spool up the turbocharger in response to receiving the traffic-related message. The controller is programmed to determine a number of relevant vehicles. The number of relevant vehicles is a number of vehicles that are in front of the host vehicle and behind a traffic light and affect a movement of the host vehicle toward the traffic light. The traffic-related message is a one of a vehicle message from another vehicle and/or a traffic-light message from the traffic light.
