    Abstract: 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.

    Abstract: 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.

    Abstract: A method for generating energy-optimized travel routes with a vehicle navigation system includes generating candidate travel routes between a route origin and one or more route destinations, and then dividing each candidate travel route into a plurality of route segments. The method includes estimating expected travel speeds along each segment using cloud information and calculating an expected energy efficiency over each of the candidate travel routes using one or more vehicle-specific energy efficiency models. The travel routes are displayed via the navigation system, including a trace of the energy-optimized travel routes and an expected or relative energy efficiency along the energy-optimized travel routes. A vehicle includes the navigation system and a powertrain. A powertrain controller may control vehicle speed over a selected route to maintain an optimally energy-efficient speed.

    Abstract: A direct-injection internal combustion engine is described and includes a pressure sensor that is disposed to monitor in-cylinder combustion pressure. A method, executed as a control routine in an attached controller, includes monitoring engine speed, engine load, temperature and combustion pressure. Combustion variation parameters are determined based upon the combustion pressure. A desired state for a combustion parameter can be determined based upon the engine speed, the engine load, and the temperature, and an adjustment to the desired state for the combustion parameter can be determined based upon the combustion variation parameters, wherein the adjustment to the desired state is selected to achieve acceptable states for the combustion variation parameters. Operation of the internal combustion engine is controlled based upon the desired state for the combustion parameter and the adjustment to the desired state for the combustion parameter.

    Abstract: A system includes a processor and a memory storing instructions which when executed by the processor configure the processor to receive data from a plurality of sensors in a vehicle, the sensors including a Global Navigation Satellite System receiver, accelerometers, gyroscopes, and magnetometers; and to determine a location of the vehicle and a direction of motion of the vehicle based on the data and a history of locations of the vehicle in prior N seconds, where N is a number greater than 0. The instructions configure the processor to determine a permitted driving direction for the vehicle based on the location of the vehicle and a map database; and to detect whether the vehicle is moving in a wrong direction based on the permitted driving direction and the direction of motion of the vehicle.

    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.
