    Abstract: A computer-implemented tool for developing electric or hybrid electric vehicle electrical components systems. Embodiments comprise a database component, a user interface component, and a processing component. The database component may store drive train components information associated with each of a plurality of drive train components, and accessory components information associated with each of a plurality of accessory components. The user interface component may be configured to enable a user to select, display and interconnect icons representing one or more of the drive train components and one or more of the accessory components as an electrical components system, to input vehicle parameters, and to display computed specification analyses. The processing component may be coupled to the database component and the user interface component, and configured to compute specification analyses for the electrical components system based on the associated drive train components information, accessory components information and the vehicle parameters.

    Abstract: An apparatus includes an input module structured to interpret a fuel pressure command indicative of a target fuel pressure within an accumulator and a target fuel injection characteristic, a pump module structured to control a pump assembly to provide fuel to the accumulator to maintain the target fuel pressure within the accumulator, an injector module structured to control a plurality of fuel injectors to inject fuel into an engine based on the target fuel injection characteristic, a pressure module structured to interpret pressure data regarding an actual fuel pressure within the accumulator and to determine a pressure difference between the target fuel pressure and the actual fuel pressure, and a modulation module structured to determine a final fuel injection command responsive to the pressure difference exceeding a first magnitude threshold where the final fuel injection command is based on the pressure difference and the target fuel injection characteristic.
