Abstract
The technology described herein provides a system and method for automatically increasing the remaining driving range of a vehicle when a low fuel or other condition is detected by altering the operating parameters of one or more vehicle systems to improve propulsion system efficiency and thereby lower fuel consumption. The vehicle range extending system is capable of altering the operating parameters of any vehicle system, including for example variable displacement settings, start-stop technology settings, and HVAC operation. The disclosed technology can also provide information to the driver, suggesting which system operating parameters should be altered to reduce the fuel consumption rate.
