Abstract: As a polymerization solvent for use in the polymerization of monomers for a hydrocarbon-based electrolyte polymer, a mixed solvent containing a first solvent, such as dimethyl acetamide, N-methylpyrrolidone or dimethyl sulfoxide, and an alcohol as a second solvent is used instead of a dimethyl acetamide/toluene mixture or dimethyl acetamide alone according to the related art. By using the mixed solvent, it is possible to obtain a molecular weight of polymer equal to or higher than the molecular weight of polymer obtained from the method according to the related art, even when the reaction time is reduced. Therefore, the disclosed method and polymerization solvent is very useful for a mass production of a hydrocarbon-based electrolyte polymer.

Abstract: A switching module switches between receiving a first output from a sensor and a second output from a sensor-less position detection module each indicating a rotor position error of a motor. A position determining module determines a rotor position of the motor based on an output of the switching module and generates a control signal to control a parameter of the motor. A sample and hold module operates on a sum of the output of the switching module and an output of the sample and hold module from a prior instance of switching between the first and second outputs. The position determining module scales the output of the sample and hold module using first and second gains to generate first and second scaled outputs, and generates the control signal based on the output of the switching module and the first and second scaled outputs.

Abstract: Presented are model-based control systems for operating parallel hybrid powertrains, methods for making/using such systems, and motor vehicles with parallel hybrid powertrains and model-based torque and speed control capabilities. A method for controlling operation of a hybrid powertrain includes receiving a command signal for a hybrid powertrain operation associated with a driver input and a current operating mode of the powertrain. A desired output torque for executing the powertrain operation is then determined. The method determines if a speed differential between an engine speed of an engine and a torque converter output speed of a torque converter is less than a calibrated threshold; if so, the method responsively engages a clutch device to operatively connect the engine's output member to the transmission's input member. Engine torque is then coordinated with motor torque such that the sum of the engine and motor torques is approximately equal to the desired output torque.
