Abstract: A system and method for routing based on a predicted connectivity quality is disclosed. The method includes receiving, by a controller, map information corresponding to a geographical area. The method also includes receiving, by the controller, wireless connectivity information corresponding to the geographical area. The method also includes generating output data of at least one route between a starting location and a destination location within the geographical area. The generating is based on the wireless connectivity information.

Abstract: A direct-injection internal combustion engine is described and includes a pressure sensor that is disposed to monitor in-cylinder combustion pressure. A method, executed as a control routine in an attached controller, includes monitoring engine speed, engine load, temperature and combustion pressure. Combustion variation parameters are determined based upon the combustion pressure. A desired state for a combustion parameter can be determined based upon the engine speed, the engine load, and the temperature, and an adjustment to the desired state for the combustion parameter can be determined based upon the combustion variation parameters, wherein the adjustment to the desired state is selected to achieve acceptable states for the combustion variation parameters. Operation of the internal combustion engine is controlled based upon the desired state for the combustion parameter and the adjustment to the desired state for the combustion parameter.

Abstract: An internal combustion engine includes an air charging system. A method to control the air charging system includes providing a desired operating target command for the air charging system, and monitoring operating parameters of the air charging system. An error between the desired operating target command for the air charging system and the corresponding one of said operating parameters of the air charging system is determined, and scheduled PID gains are determined based on the error utilizing a PID controller. An adaptive algorithm is applied to modify the scheduled PID gains, and a system control command for the air charging system is determined based upon the modified scheduled PID gains. The air charging system is controlled based upon the system control command for the air charging system.
