20170306870 | APPARATUS AND METHOD FOR CONTROLLING EGR VALVE - An apparatus for controlling an EGR valve, includes: a measurement unit to measure at least one operation condition of an engine system; a fresh air amount setting unit to set a target amount of fresh air based on the operation condition; a fresh air amount sensor to measure a current amount of fresh air introduced through an intake line; a control calculation unit to set a signal for controlling an opening degree of the EGR valve so that the current amount of fresh air follows the target amount of fresh air; and an identifier to simulate an input and an output of the engine system, and output engine system input-output sensitivity which is a ratio of a change rate of the current amount of fresh air to a change rate of the opening degree of the EGR valve. | 2017-10-26 |
20170306871 | CONDITION-BASED POWERTRAIN CONTROL SYSTEM - A system and approach for development of setpoints for a controller of a powertrain system. The controller may be parameterized as a function of setpoints to provide performance variables that are considered acceptable by a user or operator for current operating conditions of the engine or powertrain. The controller may determine set point trajectories in real time during operation of the powertrain system and determine positions of manipulated variables do drive controlled variables to associated and determined set point trajectories. The present system and approach may determine set point trajectories for powertrain conditions on-line and in real time, whereas set point trajectories have previously been determined off-line for powertrain control. | 2017-10-26 |
