Energy navigation map for e.g. hybrid vehicle, has gradient values measured and/or calculated along route and driving direction, where gradient values and sum value are utilized to display energy- and consumption-optimized routing

摘要

The map has topological gradient values (A-G) measured and/or calculated along a route and driving direction, where sum value is measured and/or calculated from the gradient. The gradient values and sum value are utilized to display and optionally convert energy-consumption-optimized routing. Additional break points are provided along the route and driving direction, and traffic jam information is processed to compute energy-efficient driving route and to display the energy-efficient driving route to a driver.
