Embodiment Construction

[0020] generally refer to Figure 1-6 , illustrating a system for range calculation in a vehicle. The system is implemented in vehicle 10 . Vehicle 10 may be any hybrid vehicle including solar powered and electric powered vehicles, internal combustion engine and electric vehicles, plug-in hybrid vehicles with batteries that draw their charge from standard electrical outlets, or fully battery powered vehicles. In general, the vehicle 10 includes a body structure 13 having a frame that surrounds and generally encloses an interior space 12 referred to as a passenger compartment. In this example, the vehicle 10 may be a plug-in hybrid vehicle powered by an internal combustion engine 17 and a battery 15 operable to be charged off-board. Both the engine 17 and the battery 15 can be used as a power source of the vehicle 10 . Each power source may independently or in a cooperative manner provide power to vehicle 10 . Hybrid vehicles that use a series configuration (eg, an engine d...

Abstract

System for calculating the operating distance range remaining for a vehicle. The system includes a driver input sensor for sensing predetermined vehicle operating condition data, an energy storage sensor for sensing energy storage capacity data of a corresponding energy supply mechanism, a controller in communication with the driver input sensor and the energy storage sensor. The controller includes a memory and a processor. An executable range calculation software program is stored in the memory of the controller which uses sensed vehicle operating condition data from the driver input sensor and sensed energy storage capacity data from the energy storage sensor to determine range by determining a mean of energy storage capacity data, determining a slope of the energy storage capacity data, determining an intercept of the energy storage capacity data, and applying a least square linear regression to the determined mean, determined slope and determined intercept to find the remaining range.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 319,553, filed March 31, 2010, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates generally to vehicles, and more particularly to systems and methods for calculating the range by which stored energy in a vehicle will be depleted and the total range of the vehicle. Background technique [0004] Vehicles (eg, motor vehicles) use energy sources to provide power to operate the vehicles. While petroleum-based products (eg, gasoline) dominate as energy sources in conventional internal combustion engines, alternative energy sources are available, such as methanol, ethanol, natural gas, hydrogen, electricity, solar energy, or the like. Hybrid vehicles (referred to as "hybrid vehicles") use a combination of energy sources to power the vehicle. For example, batteries may be us...
