Abstract: Systems and methods for transmission gear shift management of a vehicle having cooperative adaptive cruise control (CACC) are provided. A method includes: enabling a cooperative adaptive cruise control (CACC) mode of a vehicle; updating a transmission shift map to adjust at least one threshold associated with a transmission shift event in response to enabling the CACC mode of the vehicle; receiving a torque demand from the vehicle in response to enabling the CACC mode of the vehicle; determining a transmission shift event based on the received torque demand and the updated transmission shift map; and implementing the determined transmission shift event.

Abstract: The present disclosure relates to the use of power-agnostic mobile vehicles, including internal combustion, hybrid, fuel cell, and battery electric vehicles, which can collectively transfer power back to the grid in ever larger and growing quantities of power. In other words, the present disclosure relates to the use of a network of vehicles to act as a grid.

Abstract: Systems and methods for data analysis of vehicle data, such as engine data, are provided. A provider computing system includes a communication interface structured to couple to a network, one or more processors, and at least one memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations. The operations include: receiving, from a user device and via the network, a first data packet comprising information associated with a vehicle. The operations also include analyzing the first data packet to output a second data packet comprising repair priority information. The operations also include transforming the second data packet into a human-readable message comprising the repair priority information. The operations also include transmitting, via the communication interface and the network, the human-readable message to the user device.

Abstract: A pressure-based piston top-dead-center (“TDC”) position measurement system is disclosed, comprising: a fuel injector configured to inject fuel into a combustion chamber bounded in part by the piston; and a controller configured to control the fuel injector to cause a fuel injection when the piston is at each of a plurality of different positions relative to TDC while ensuring fuel is provided to the fuel injector at a substantially constant pressure. The controller is further configured to estimate a pressure in the combustion chamber in response to each fuel injection, fit a curve to the estimated pressures, and determine a TDC position of the piston as correlating with a maximum pressure on the curve.

Abstract: A vehicle includes a powertrain with a prime mover, a transmission with a number of gears, and foundation brakes. The speed of the vehicle along a downhill route segment is automatically controlled toward a target speed by prioritizing the use of engine braking power and gear downshifting in the transmission over application of the vehicle's foundation brakes.

Abstract: A system is configured to store a relationship data set of a plurality of diagnostic estimators and a plurality of failure modes, each failure mode represents a type of failure that can occur with a sensor or a vehicle component of a vehicle system, each diagnostic estimator is associated with a respective subset of the failure modes, each subset defines a control space within the vehicle system that contains at least one of (i) one or more sensors or (ii) one or more vehicle components. The system is configured to store a healthy diagnostic vector regarding nominal operational parameters of the vehicle system; acquire diagnostic information regarding current operational parameters of the vehicle system to generate an error diagnostic vector; apply the error diagnostic vector to the healthy diagnostic vector to generate a ratio diagnostic vector; and apply the ratio diagnostic vector to generate a value for each failure mode.

Abstract: A system, method, and apparatus for decreasing harmful emissions is provided. The system includes an aftertreatment system configured to receive exhaust gas from an engine system; a heater coupled to the aftertreatment system and configured to provide heat; and a controller coupled to the heater. The controller is configured to: determine that the engine system is idling; in response to determining that the engine system is idling, determine whether a value regarding operation of the engine system is greater than a threshold value; in response to determining that the value is greater than the threshold value, determine whether a temperature regarding the aftertreatment system is greater than a threshold temperature; and in response to determining that the temperature of the aftertreatment system is greater than the threshold temperature, at least one of disable or partially disable the heater.
