Abstract: A method of controlling one or more vehicles of a platoon of vehicles includes determining in response to information of forward route conditions of the platoon an opportunity to mitigate braking losses, performing regenerative braking in response to a deceleration output of an cooperative adaptive cruise control (CACC) system, adjusting an inter-vehicle distance of the CACC system, and performing at least one of the regenerative braking and the adjusting the inter-vehicle distance.

Abstract: Systems and methods to extend a life of a component of a cylinder deactivation system are provided. A method includes generating, by a controller, an initial life factor for the component; initiating, by the controller, a CDA mode for an engine; determining, by the controller, an actual life factor for the component, the actual life factor determined by comparing a number of switching events of a cylinder in the CDA mode to a number of cycles of the cylinder in the CDA mode; comparing, by the controller, the actual life factor to the initial life factor; and modifying, by the controller based on the comparison, operation of the engine in the CDA mode to adjust the actual life factor.

Abstract: Adaptive cruise control apparatuses, methods, and system are disclosed. In one embodiment, an electronic control system of a following vehicle detects a preceding vehicle, the following vehicle is controlled to follow the preceding vehicle at an initial following distance, the initial following distance is perturbated, and the following distance is modified if the perturbated following distance offers a fuel or energy benefit.

Abstract: This disclosure provides a system and method for controlling internal combustion engine system to reduce operation variations among plural engines. The system and method utilizes single-input-single-output (SISO) control in which a single operating parameter lever is selected from among exhaust gas recirculation (EGR) fraction and charge air mass flow (MCF), and a stored reference value associated with the selected lever is adjusted for an operating point in accordance with a difference between a measured emissions characteristic and a pre-calibrated reference value of the emissions characteristic for that operating point. Adjusting the selected operating parameter lever towards the theoretical pre-calibrated reference value of the operating parameter lever for each of plural operating points can reduce engine-to-engine variations in engine out emissions.
