Abstract: A system and method of operating an exhaust gas recirculation (EGR) system of a vehicle includes controlling an EGR valve actuable between an EGR enabled position and an EGR disabled position, such that with the EGR valve in the EGR enabled position a portion of exhaust gas emitted from an engine is directed through an EGR cooler for recirculation into the engine, and with the EGR valve in the EGR disabled position the exhaust gas is not recirculated through the engine. An EGR coolant temperature is predicted based on measured engine speed, vehicle speed, outside ambient temperature, and commanded fuel level of the vehicle. The EGR valve is actuated to the EGR disabled position when the predicted EGR coolant temperature is equal or greater than an EGR coolant temperature threshold. The EGR coolant temperature is predicted without direct measurement of engine coolant temperature.

Abstract: A vehicle includes an engine having cylinders in fluid communication with an intake air flow, a mass air flow (MAF) sensor positioned with respect to the intake air flow which outputs a pulse train signal describing the frequency of the intake air flow, and a controller. The controller includes a calibrated non-linear conversion curve recorded in memory. The controller executes a method to convert the frequency data into a corresponding mass air flow using the calibrated non-linear conversion curve, determines the instantaneous mass air flow value at each leading or trailing edge of the pulse train signal, and accumulates the instantaneous mass air flow values over a calibrated duration. A time-weighted average of the accumulated mass air flow values is then used to execute a control action. The controller includes a host computer device and memory storing the curve and instructions for executing the method.
