Abstract
A method for determining an estimated driving range for a vehicle that uses battery power for vehicle propulsion, where the estimate is in the form of a range of values as opposed to a single value. In one embodiment, the method adds a positive offset value to an initial estimate value to determine an upper limit, and subtracts a negative offset value from the initial estimate value to determine a lower limit. The positive and negative offset values may be determined separately and on a real-time basis so that the extent of the overall estimated driving range may be influenced by the volatility in power consumption and/or power creation.
