  • Method of calculating a route based on estimated energy consumption
    Patent number: 7493209
    Abstract: A method of calculating a navigation route based on an estimated energy consumption value that assigns a distance weight coefficient for each of the plurality of potential routes that corresponds to an estimated distance energy consumption value. The method also determines a cumulative interference weight coefficient for each of the plurality of potential routes corresponding to an estimated interference energy consumption value based on traversing at least one interference event in the potential route. Each cumulative interference weight coefficient may include a fixed event interference weight coefficient, a probable event interference weight coefficient, and a scheduled event interference weight coefficient.
