Embodiment Construction

[0020] figure 1 A motor vehicle 100 is shown. Motor vehicle 100 includes internal combustion engine 105 , which is connected to engine control unit 110 . The engine control unit 110 controls the supply of liquid fuel, such as diesel or gasoline, to the internal combustion engine 105 . In other embodiments, other types of engines can also be used, the fuel of which is metered by means of the engine control unit 110 , for example an electric motor, wherein the fuel is electrical energy. Motor vehicle 100 also includes navigation device 115 , which includes processing device 120 , GPS antenna 125 , TMC antenna 130 , map memory 135 and interface 140 .

[0021] The processing means 120 is preferably a digital microcomputer. Map memory 135 contains information about the road network on which a route between a starting point and a destination can be determined. This information contains segments of roads on the route network, to which attributes are assigned to each. These prope...

Abstract

A navigation method for determining a fuel-efficient route of a motor vehicle between a start point and a destination point comprises on a predetermined path network steps of determining the consumption value of the vehicle on a section of the road network on the basis of another on a section of the road network collected consumption value of the vehicle and determining the fuel-efficient route based on the specific consumption value.

Description

technical field [0001] The invention relates to a navigation method and a navigation device for determining a route of a motor vehicle, more particularly to a navigation method and a navigation device for determining a consumption-optimized route. Background technique [0002] Navigation systems for determining a route of a motor vehicle between a starting point and a destination are generally known. Some of these navigation systems allow the route to be determined as optimized with respect to the road traveled between the origin and the destination, or as an optimization of the time required to travel a road segment. In addition, known navigation systems provide routes determined in such a way that the fuel consumption of the motor vehicle or the accompanying fuel consumption, such as CO 2 Emissions of pollutants, usually based on the speed curve of the motor vehicle to obtain an estimate of the consumption on the route. Technical parameters of the motor vehicle, such as ...
