Abstract: A turbocharger controller includes a turbocharger compressor temperature module having a compressor inlet air temperature input, and a turbocharger compressor pressure module including a compressor inlet pressure input and a compressor outlet pressure input. A memory module includes a compressor outlet temperature calibration map and a compressor pressure ratio look-up table. A turbocharger boost pressure ratio control module is operatively connected to the turbocharger compressor temperature module, the turbocharger compressor pressure module, and the memory module. The turbocharger boost pressure ratio control module is configured to selectively compare compressor outlet pressure and compressor inlet pressure with values in the compressor ratio look-up table to determine a turbocharger boost pressure set point establishing a desired compressor outlet 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.
