Abstract
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).
Claims18
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);
- a clock;
- and
- a processor containing a function executing therein that controls the internal combustion engine based on a GPS fix.
A method 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:
- receiving a global positioning system (GPS) fix;
- receiving map data;
- determining a horizontal dilution of precision (HDOP) of the GPS fix;
- for a given internal combustion engine control function, determining when the HDOP exceeds a predetermined threshold;
- when the HDOP does not exceed its predetermined threshold, enabling or maintain enabled the internal combustion engine control function.
