Under, step 404 is executed, in the case where judging that arcuate distance is greater than threshold value, executes step 405.
Server calculate the camber line between the first coordinate points and the second coordinate points distance after, it can be determined that the radian away from
From whether threshold value is greater than, in the case where judging arcuate distance no more than threshold value, execute step 404, judge radian away from
In the case where being greater than threshold value, step 405 is executed.
404, server determine arcuate distance be traveling of the trailer between first time information and the second temporal information away from
From.
In the case where judging arcuate distance no more than threshold value, show between first time information and the second temporal information
Operating range it is smaller, more accurate using above method calculated distance, therefore, server can determine arcuate distance
The operating range for being trailer between first time information and the second temporal information.
405, server determines trailer first according to first location information, second location information and history driving trace
Operating range between temporal information and the second temporal information.
In the case where judging that arcuate distance is greater than threshold value, show between first time information and the second temporal information
Operating range is larger, and using above method calculated distance inaccuracy, therefore, server can be believed according to first position
Breath, second location information and history driving trace, determine traveling of the trailer between first time information and the second temporal information
Distance.Can first from all driving paths chosen in history driving trace between first location information and second location information,
The most driving path of access times in the driving path of selection is determined as the trailer in first location information and the second position
Driving path between information calculates the length of determining driving path later.History driving trace can be all of storage
The history driving trace of trailer.The length that determining driving path can be calculated by electronic map, can also pass through other
Mode calculates the length of determining driving path, is not limited thereto.
The distance described in Fig. 4 determines in method, two it is adjacent report time interval shorter in the case where, server
Can directly according to the information that trailer reports determine trailer in the operating range of this section, two it is adjacent report time interval compared with
In the case where length, it can be hung according to the driving trace of this section of history driving trace completion trailer so as to accurately determine
The operating range of vehicle.
