    Abstract: Systems and methods for autonomous vehicle control are provided. A remote computing system includes a communication interface coupled to a network, a map database storing centralized map data, a processor, and a memory storing instructions that, when executed by the processor, cause the processor to perform operations. The operations include: receiving a transport request including a first location and a second location; selecting a first vehicle of a plurality of vehicles for the transport request based on at least one of the transport request and a vehicle status; transmitting the centralized map data to the first vehicle; causing the first vehicle to complete the transport request, including causing the first vehicle to autonomously transport from the first location to the second location and causing the first vehicle to collect first sensor data; receiving the first sensor data in real-time; and, updating the centralized map data with the first sensor data.

    Abstract: A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.

    Abstract: A system and method for measuring fuel pressure decreases in a fuel accumulator of an internal combustion engine is provided. The system includes the ability to stop a fuel flow to a fuel accumulator of the engine. Pressure signals are transmitted to a control system of the engine until the fuel pressure in the fuel accumulator drops by a predetermined amount, at which time fuel flow is re-enabled. The pressure signals are then analyzed to determine the amount or quantity of fuel delivered by each fuel injector. The system and method maintain engine and emissions performance by limiting the amount of fuel pressure decrease in the fuel accumulator.
