Abstract: A vehicle includes drive wheels, an energy source having an available energy, a torque-generating device powered by the energy source to provide an input torque, a transmission configured to receive the input torque and deliver an output torque to the set of drive wheels, and a controller. The controller, as part of a programmed method, predicts consumption of the available energy along a predetermined travel route using onboard data, offboard data, and a first logic block, and also corrects the predicted energy consumption using the onboard data, offboard data, and an error correction loop between a second logic block and the first logic block. The controller also executes a control action with respect to the vehicle using the corrected energy consumption, including changing a logic state of the vehicle.

Abstract: A method of controlling temperature of a coolant supplied to a battery pack includes detecting a request for charging the battery pack, and commanding, via the electronic controller, a rate of charge of the battery pack. The method also includes determining the dew point inside the battery pack during the charging. The method additionally includes commanding a supply of coolant to the battery pack while the battery pack is charging. The method also includes regulating a temperature of the coolant to maintain the battery pack above the determined dew point during the charging. The method may further include maximizing the rate of charge at the regulated temperature of the coolant. A battery system employing an electronic controller configured to perform such a method, and a motor vehicle using such a battery system are also within the scope of the present disclosure.

Abstract: A method for adapting a usage level of a battery pack includes measuring cell sense data for each respective battery cell using a cell sense circuit, the cell sense data including a cell voltage, current, and temperature. The method includes processing the cell sense data, for each respective battery cell, through multiple battery state functions of a controller to generate numeric cell degradation values (CDVs). The battery state functions are calibrated relationships of the cell sense data to predetermined battery fault conditions. Thereafter, the method includes automatically adapting the usage level of the battery pack during operation of the battery pack, via the controller, based on the numeric CDVs. An electric powertrain system includes the battery pack, cell sense circuit, a rotary electric machine, and a controller configured to execute the above method.

Abstract: A method of controlling a ground vehicle includes providing the vehicle with a first sensor configured to detect a vehicle position, a second sensor configured to detect a driven path of the vehicle, and a controller. The method also includes obtaining, via the first sensor, a plurality of vehicle position coordinates during a time interval of a drive cycle, and calculating, via the controller, a first path curvature parameter based on the plurality of vehicle position coordinates. The method additionally includes obtaining, via the second sensor, a second path curvature parameter based on the driven path during the time interval. The method further includes comparing, via the controller, the first path curvature parameter to the second path curvature parameter, and in response to a difference between the second path curvature and the first path curvature exceeding a threshold, automatically operating the controller according to a diagnostic mode.

Abstract: A vehicle including an energy storage device and a powertrain system configured to effect regenerative braking is described. A method for controlling the vehicle includes determining an expected increase in a state of charge of the energy storage device achieved through opportunity charging by employing regenerative braking during an anticipated next trip of the vehicle. A preferred setpoint for the state of charge of the energy storage device is determined based upon the expected increase in the state of charge achieved through opportunity charging, and charging of the energy storage device is controlled during a remote charging event based upon the preferred setpoint for the state of charge of the energy storage device.
