    Abstract: Examples of techniques for controlling coolant flow in a vehicle cooling system for an internal combustion engine using a secondary coolant pump are provided. In one example implementation, a computer-implemented method includes receiving, by a processing device, engine operation data about the internal combustion engine. The method further includes detecting, by the processing device, a shutdown of the internal combustion engine. The method further includes calculating, by the processing device, an engine flow based at least in part on the block flow request and the head flow request. The method further includes, subsequent to detecting the shutdown of the internal combustion engine determining, by the processing device, an after-run condition based at least in part on the engine operation data. The method further includes activating, by the processing device, a secondary coolant pump based at least in part on determining the after-run condition.

    Abstract: A method for selecting an engine operating point in a multi-mode powertrain system includes monitoring a desired axle torque based on an operator torque request and vehicle speed. When an aftertreatment device used to purify regulated constituents within an exhaust gas feedstream output from the engine is determined to require an exhaust gas feedstream temperature to be increased to a predetermined temperature, an intrusive engine operation mode is enabled to increase the exhaust gas feedstream temperature to the predetermined temperature. A plurality of engine power is retrieved, wherein each engine power loss corresponds to respective ones of a plurality of intrusive engine operation points each achieving the predetermined temperature of the exhaust gas feedstream. A desired engine operation point is selected corresponding to one of the intrusive engine operation points having a lowest total power loss.

    Abstract: A system and method can control exhaust braking in a vehicle. The vehicle includes an engine system. The engine system includes internal combustion engine, an intake manifold, a control module, an exhaust system, and a variable geometry turbocharger (VGT) having a turbine. The turbine includes turbine blades and vanes movable with respect to the turbine blades. The method includes the following: (a) receiving an exhaust brake torque request; (b) determining target pumping losses in the internal combustion engine based on the exhaust brake torque request; (c) determining a target exhaust gas pressure within the exhaust system based on the target pumping losses; and (d) determining a target vane position of the vanes based on the target exhaust gas pressure, wherein the target vane position yields an exhaust brake torque in accordance with the exhaust brake torque request.
