Description

A kind of navigation map update method and device thereof based on the GPS navigation instrument
Technical field
The present invention relates to the GPS navigation device, relate in particular to a kind of navigation map update method and device thereof based on the GPS navigation instrument.
Background technology
The GPS navigation system is more and more universal, but existing navigational system can only be navigated according to built-in electronic chart.In the Vehicle Driving Cycle process, because the GPS navigation system do not upgrade in time, can't reproduce strange route, can not be driver's efficiently information of providing convenience.Because the town and country construction of China is maked rapid progress, urban and suburban roads annual rate of change is larger, the product that China's map of navigation electronic market renewal frequency is the highest also can only be accomplished to upgrade 2 times in important city year, upgrade in provincial capital and general city year and only have 1 time, road data upgrades and is difficult to guarantee on a large scale, causes a large amount of misguidances.
Open day be that on 01 19th, 2011, publication number are that the patent documentation of CN101949706A discloses such technical scheme, a kind of navigating instrument with memory function, relate to navigating instrument, relate in particular to and a kind ofly start the navigating instrument that the memory navigation can be guided route with memory module for the second time going to same local time; Comprise shell, GPS display terminal and GPS chip, the GPS display terminal comprises display and loudspeaker, and the GPS chip is arranged on enclosure, and display is arranged on case surface, and loudspeaker is located at case back; Also comprise memory module, mileage tracking module, mileometer circuit and microprocessor; Its beneficial effect is: when the second time, same departure place left for same destination, only need to open memory navigation starting button, even when not having navigation signal, navigating instrument still can be made correct navigation for the driver.The weak point of this scheme is: memory module has only recorded navigation information and mileage on the route that has existed on the navigation picture, Vehicle Driving Cycle is crossed, and for secondary this route that travels is provided convenience, can not carry out route to existing navigation picture and augment renewal.
Summary of the invention
The present invention solves the existing navigation map route of prior art to augment, upgrade the technical matterss such as untimely, and a kind of navigation map update method and device thereof based on the GPS navigation instrument is provided.
The present invention is directed to the prior art problem and mainly solved by following technical proposals, a kind of navigation map update method based on the GPS navigation instrument comprises the steps:
A, a vehicle-mounted GPS navigator communicate with a route processing unit and are connected, and route processing unit practical function comprises latitude and longitude information, the processing of route track of reading in real time current location;
B, when in vehicle-mounted GPS navigator, can not find out the destination, then open the route processing unit, longitude and latitude sampling and record are carried out in institute's route via pointwise from origin to destination, arrive add the departure place title behind the destination, the destination title together is stored as the specified format file;
C, route processing unit be according to described specified format file, and it is a new navigation way that the sampled point with longitude and latitude is carried out successively from first to last that track is formed by connecting, and this new navigation way is sent to vehicle-mounted GPS navigator.
The method increases a route processing unit on existing vehicle-mounted GPS navigator basis.After the title of vehicle-mounted GPS navigator input destination, if can retrieve this destination, then allow the vehicle-mounted GPS navigator navigation feature of bringing into normal play, travel by navigation way; If retrieval is less than the destination, illustrating that existing navigation map does not upgrade can't provide navigation, this moment, the driver travelled by rule of thumb or from the information that other approach are known, behind vehicle launch, open the latitude and longitude information that reads in real time current location in the route processing unit travel route is carried out the longitude and latitude sampling, finish sampling after arriving the destination, input departure place title and destination title and longitude and latitude sampled data together are stored as a file by specified format; The route processing unit is by this specified format file, it is a new navigation way that sampled point with longitude and latitude is carried out successively from first to last that track is formed by connecting, and this new navigation way is sent to vehicle-mounted GPS navigator, for this navigating instrument has increased again a new navigation way.
