    Abstract: A vehicle is described, and includes a drivetrain system including an internal combustion engine and a geartrain, an accessory device, and a route monitoring system. A controller includes an instruction set to monitor operation of the accessory device, and a request to operate the accessory device. When the request to operate the accessory device includes a request to activate the accessory device based upon not exceeding a limit for an operating parameter of the accessory device, the instruction set executes to determine a horizon for the vehicle based upon the projected path for the vehicle, determine a projected road load and a speed constraint based upon the horizon for the vehicle, and determine a projected axle torque command based upon the projected road load. A first routine determines a first command for operating the accessory device that minimizes fuel consumption and meets the projected axle torque command.

    Abstract: A battery monitoring system for a vehicle includes a processor and a memory. The memory stores instructions for causing the processor to estimate a state of charge of a battery based on a current cell pressure of the battery while the state of charge of the battery is below a threshold state of charge and to estimate a state of charge of the battery based on a voltage output by the battery while the state of charge of the battery is greater than or equal to the threshold state of charge.

    Abstract: A vehicle includes a pressure control device for controlling a pressure at a battery of a vehicle and a method of controlling the pressure of the battery. A support plate is disposed at a first side of the battery. A pressure plate disposed at a second side of the battery opposite the first side. The pressure plate movable with respect to the support plate to control the pressure of the battery. A cam disposed at the pressure plate is configured to rotate to move the pressure plate with respect to the support plate. A cam shaft rotates the cam to move the pressure plate. A motor generates a rotation at the cam shaft.

    Abstract: A vehicle, system and method of operating a battery having a plurality of modules, each module having a plurality of strings. The vehicle includes the battery. A processor operates the plurality of modules in a first phase of a mode of operation, calculates a model-predicted path vector for the first phase based on a time for reducing a difference between states of charges of the plurality of strings, selects between the model-predicted path vector and a default path vector based on an operating parameter of the battery, and switches operation of the plurality of modules from the first phase to a second phase using the selected one of the model-predicted path vector and the default path vector.

    Abstract: In various embodiments, systems, apparatuses and methods are provided to distribute coolant to an electric motor. The apparatus includes a pan configured with a set of holes for coolant flow; an assembly including a set of bar linkages, a set of discs, and a single actuator motor wherein the assembly is attached to the pan wherein the single actuator motor is linked via bar linkages to discs that enable configuring a planar angle of the pan to obtain an optimum hole location of holes for coolant flow; and in response to external disturbances to the apparatus that redirect the coolant flow from the target region of the electric motor, the single actuator motor is controlled by an algorithm to change the planar angle of the pan to obtain the optimum hole location to direct coolant flow to the target region of the electric motor.
