Description
Technical field
The present invention relates to a kind of device be used to enriching road data, it has the orientation receiving element that is configured to determine the orientation (Position) on traffic route.In addition, the present invention relates to a kind of be used to utilizing this device to enrich the method for road data and computer program for this reason and computer program.
Background technology
Known such navigator, that is, it has the orientation receiving element, and via satellite or for example receive as the bearing data of the form of gps data, GALILEO data by the mobile wireless remote sensing technology and navigate on traffic route being used for.In known manner, road data relates to the geographic position of traffic route, and can utilize so-called point of interest to enrich this road data or utilization is that remain unchanged for a long period of time or this road data is enriched in traffic prompting real-time update or traffic indication.
In addition, known stored is about the altitude information of the landform height above sea level of traffic route, if and for example motor vehicle moves, can together with road data, this information be offered driver or driver assistance system equally by the altitude information that is stored on traffic route.At this, obtain the position of geography of road and relevant altitude information cost very high and realize by crossing traffic route, wherein, use point-device GPS measuring system.Yet, although use this accurate system, at the height above sea level of its corresponding measurement of bearing traffic route still with very high error.Known in addition, also can provide altitude information by the orientation receiving element by GPS navigation, yet this altitude information is not accurate enough equally.
In order to save energy in road traffic, known such method, that is, it is based on the velocity distribution of the gradient distribution calculation optimization of the traffic route in the place ahead, and this velocity distribution is given to the driver of motor vehicle or is arranged in opertaing device place in motor vehicle.Yet when realizing the method, the gradient distribution of known traffic route is necessary exactly.Derive this gradient distribution in can the altitude information from be stored in map datum, however thus for the driver assistance system at the opertaing device place that is used for for example energy-conservation driving mode being provided to driver or motor vehicle can with gradient distribution obtain equally very large inaccuracy.
Same known such method namely, utilizes these methods will be from the communication of destination guidance system to the central server place, to be used for gathering these information at this place.For example, can be collected in the spended time on road interval and it is transferred to the central server place in navigational system, can calculate passage rate thus.
For example, the method that becomes known for calibrating the height above sea level measuring instrument from file US 6,381,540 B1, wherein, the height above sea level that calculates is based on the pressure survey of air pressure, and wherein, the height above sea level that calculates is also based on gps system, wherein, in the time should not relying on the pressure survey of air pressure, when calculate differ certain value based on the height above sea level of the pressure of air pressure and the GPS height above sea level that calculates the time, the height above sea level based on the pressure of air pressure that calculates is compared with the height above sea level that calculates by gps system.In order to determine the gradient distribution of traffic route, the measurement of the height above sea level of air pressure and really establish a capital inaccurate based on the height above sea level of GPS information.Usually, two height above sea level that record with certain each interval are compared, thereby can determine the gradient of traffic route from height above sea level is poor.Yet in order to make thus the person's of sailing backup system operation at the opertaing device place that energy-conservation driving mode should be provided to driver or motor vehicle, the method obtains is used for determining that the accuracy of gradient distribution of traffic route is not enough.
Become known for utilizing altitude information to enrich the device of road data from document JP 2,007 003 195 A, this device is based on the GPS location of three-dimensional.Be known that thus the altitude information based on gps data combines with road data and for example is stored.Yet for the energy-conservation driving mode that will work in a satisfactory manner offers driver assistance system, the method is also accurate not.
