Navigational method for determining consumption-optimized route of motor car, involves determining consumption value of motor car on portion based on another consumption value detected on another portion of road network

摘要

The method involves determining a consumption value (230) of a motor car on a portion of a road network. A consumption-optimized route is determined based on the determined consumption value. The consumption value of the motor car on the portion is determined based on another consumption value (240) detected on another portion of the road network, where the geographical attributes (220) of the portions comprise comparable values. Deviation of the determined consumption values is minimized by a mathematical model. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions for performing a method for determining a consumption-optimized route of a motor car between a start point and a target point on a road network (2) a navigation device for determining a consumption-optimized route of a motor car between a start point and a target point on a road network.
