Embodiment one

Such as Fig. 1, in the embodiment of the present invention one, there is provided a kind of generation method of running data, comprise the steps：

S111:Obtain driving information；

In the method for obtaining driving information, can be recorded by external equipment, be transmitted, it is also possible to directly be set by navigation The standby data for obtaining.

S112:Obtain positional information represented when driving information is produced；

S113：The positional information that will be obtained in S112 matches with map datum, obtains the corresponding road information in the position；

The road information is the section letter in the corresponding map datum of positional information represented when the driving information is produced Breath.

S114：Road information and driving information associated storage will be obtained, that is, will make and store running data；

S115：Set up the index relative of running data and map datum；

Preferably, this method is applied in guider, and the map datum described in S113 steps is map datum in navigation.

It is not limited in the specific implementation this method indexed in S115 steps, is set forth below two kinds and preferably implements mode：

Mode 1：With known in industry, map datum is stored using piecemeal, and the mode of multiple index, running data can also be adopted Running data is managed with the index relative as map datum used by navigation equipment.

Mode 2：Navigation map data is associated with the relation of running data by road markings, by setting up road markings Index is completed with the relation table of the specific storage location of running data, concordance list is ranked up according to road markings numerical values recited. In certain running data of road is read, as long as searching concordance list, it is possible to obtain the particular location of data, due to index Table in order, very big lifting is had using binary chop performance according to road markings, by this way to the access of data Performance can be receiving.

The data form of the running data generated by this method corresponding with the electronic map data foundation in navigation equipment can be closed System, and establish the index relative of road and running data associated there in map datum.Traveling is lifted by indexing The reading performance of data, solves the performance issue of a large amount of traveling digital independents of storage, improves the speed for reading.

Further, vehicle is during traveling, matches (step during determination vehicle running section with map datum Rapid S113), when in vehicle location to specific section, section unique mark is obtained from map datum, preferably judge current Whether section needs to divide, and for being capable of one section of road of unique mark in map datum, some road distance length can be very long, As some sections can be more than tens kms, it is clear that distance so long is unlikely to be a same speed, it is desirable to accomplish Running data to each section does the record that becomes more meticulous, it is necessary to some specific road sections in the light of actual conditions, using one A little technical methods are divided.

Such as Fig. 2, preferably partiting step is as follows in the present invention：

S121:The details in the section that road information is uniquely determined in acquisition S113；I.e.：Corresponding road is obtained from map datum The details of section, main some characteristic values comprising road are such as：Length, road shape information, altitude information, gradient letter Breath, bridge, tunnel is overhead, rotating disk etc..
