Method and systems for emissions compliant use of telematics inputs to a propulsion control system for function enablement

摘要

Systems and methods are provided to allow for reliable consumption of GPS and Map information into a Control System, for such uses as improving off cycle fuel economy in a plug in hybrid vehicle with an electric motor, and an internal combustion engine using a global position system (GPS) is provided. The system comprises a global position system (GPS), a clock, and a processor containing a function executing therein that controls the internal combustion engine based on a GPS fix and its Accuracy Information (VDOP/HDOP/Satellite Quantity).

1. A system for improving off cycle fuel economy or other emissions in a hybrid vehicle with an electric motor and an internal combustion engine using a global position system (GPS) comprising:
a global position system (GPS); and a processor containing a function executing therein that controls the internal combustion engine based on a GPS fix, wherein the processor is configured to:
receive a horizontal dilution of precision (HDOP);determine when the HDOP is below a predetermined threshold associated with the function;disable or maintain the function disabled when the HDOP is not below the predetermined threshold; andenable or maintain the function enabled when the HDOP is below the predetermined threshold.
