Specifically, in the present embodiment, the navigation object is to be mounted with that the embodiment of the present invention is provided on automobile, the automobile
Guider, for user driving navigation way is provided.In actual applications, after user opens the guider,
The guider will obtain the position that automobile (i.e. described navigation object) is currently located automatically by built-in gps receiver,
The usual position can be used as departure place.Then, user inputs destination on the display of guider, wherein the purpose
Ground can be specific road name and guideboard number (such as crossdrift No. 211 all the way), can also be specified place (such as Four Seasons Hotel).
It should be noted that in the present embodiment, the guider is according to the departure place of above-mentioned determination and purpose
Ground has calculated a bar navigation route.Further, guider will be drawn according to departure place and destination on the electronic map
One reference route, the reference route be one using departure place and destination as the straightway of two-end-point, identify from starting point
The direction (i.e. step S1) of the navigation way is indicated to the direction of destination, that is, the reference route.As can be seen that this
In reference route be not that guider calculates the obtained navigation way from the departure place to destination, the reference route
What is actually represented is the direction of navigation, i.e., the direction arrived at from departure place.In actual applications, guider is shown
The colouring discrimination of the reference route shown on device is in navigation way, in order to the user discrimination reference route.
Then, the satellite of known location is measured by the gps receiver built in guider to the gps receiver
The distance between (i.e. navigation object), then the data in conjunction with multiple satellites be assured that the specific position of the navigation object
Put, then shown the current location information of the navigation object on the electronic map by the display of the guider
(i.e. step S2).Wherein, the operation principle of the gps receiver is known to the skilled person technology, will not be repeated here.
Further, in the present embodiment, the current location information includes the seat navigation object on the electronic map
Mark information.It will be appreciated by those skilled in the art that the current location of the general navigation object got by gps receiver is logical
Cross gps coordinate to represent, the gps coordinate is built upon in the coordinate system of real world, by two parameters of longitude and latitude
To represent.Guider needs the gps coordinate being converted into local Gauss plane coordinate, to realize gps coordinate electronically
Correct matching in figure.The process that specific gps coordinate is converted into local Gauss plane coordinate is as well known to those skilled in the art
Technology, will not be described here.
Then, the current location information based on the navigation object determines the navigation object relative to the reference route
Angle offset parameter (i.e. step S3).
This step includes：First, according to the current coordinate information on the electronic map of the navigation object, institute is determined
State the angle angle between navigation object and the line and the reference route of the departure place.
Specifically, with reference to Fig. 2, it is assumed here that A points are that departure place, B points are destination；AB straightways 00 are the departure place
The navigation way that reference route, AB curved sections 01 to destination are the departure place A to destination B.Navigation object (does not show
Go out) it is current by way of C points from A points, i.e., described C points are the current location of the navigation object, on the electronic map can be true
The coordinate information of the fixed C points.Now, the folder between the C points and the line AC and the reference route of the departure place A points
Angle angle is α.Because each Points And lines section on the electronic map all has coordinate information, and utilize the goniometer of guider
Function is calculated, those skilled in the art can calculate the angle angle [alpha], and therefore not to repeat here for its calculating process.
Then, the angle based on navigation object described in the angle angle-determining relative to the reference route offsets ginseng
Number.In a present embodiment, it is preferred that directly the angle angle [alpha] that obtains above-mentioned calculating as the navigation object relative to institute
The angle offset parameter of reference route is stated, but in actual applications, however it is not limited to this.Because the coordinate information on electronic map exists
It is possible that error in calculating process, therefore can also be described to determine based on obtained angle angle [alpha] plus-minus error is calculated
Angle offset parameter.
Correspondingly, in step s 4, when the angle offset parameter is more than angle threshold, time parameter is recorded, wherein,
The time parameter identifies the angle offset parameter and is more than angle threshold duration.
In the present embodiment, it is right angle to set the angle threshold, i.e., when the navigation object current location (i.e. C points) and
When angle angle [alpha] between the line AC and the reference route of the departure place A is more than 90 degree, it is determined that presently described navigation
Object deviate from the direction (direction of destination in other words) of the reference route, but now the navigation object may have must
The direction of the reference route is temporarily deviate from, in practical situation, navigation object may need to enter neighbouring high-grade road
Road, such as highway, it is overhead section.Accordingly, it would be desirable to further consider time factor, determine that the navigation object starts partially
Play duration in direction from the reference route.
With continued reference to Fig. 2, navigation object it is current by way of C points when, the angle angle [alpha] is more than 90 degree, now starts to remember
Record time parameter.Then, the navigation object continues on arrival C ' points, now, line of the C ' points with departure place A points
Angle angle between AC ' and the reference route is α ', it is assumed that the angle angle [alpha] ' also greater than 90 degree.Can be with from Fig. 2
Find out, when navigation object is from during C points advance to C ' points, the navigation object and departure place A line and the benchmark
Angle angle between route is greater than 90 degree all the time, i.e., in this period parameter t, the angle offset parameter is both greater than
Angle threshold.It should be noted that the angle threshold (90 degree) set by the present embodiment is only reference value, in actual applications,
Other angle values can also be set as the angle threshold.
Then, when the time parameter is more than very first time threshold value and less than the second time threshold, instruction is issued the user with
Information, wherein the configured information is used for direction (the i.e. step for indicating that the navigation object revert to the reference route
S5)。
In the present embodiment, the very first time threshold value and the second time threshold can the length based on the reference route
To determine.Generally, if the distance between departure place and destination are more remote, i.e., the length of described reference route is longer, then can be with
Determine that the time of the very first time threshold value and the second time threshold is longer.And if the distance between departure place and destination compared with
Closely, i.e., the length of described reference route is shorter, then can determine time of the very first time threshold value and the second time threshold compared with
It is short.In other embodiments, the very first time threshold value and the second time threshold can also the length based on navigation way come really
It is fixed.Further, the very first time threshold value is less than second time threshold,
The time parameter t obtained according to above-mentioned steps S4, if the time parameter t is more than the set very first time
Threshold value and less than the second time threshold, it is believed that although the navigation object has deviateed the direction of reference route, offset is not
Greatly, therefore by issuing the user with configured information the direction for guiding user to make the navigation object revert to reference route again
On.Wherein, the mode for issuing the user with configured information can be that the configured information directly is included into the display in guider
On device, or by configured information described in player voice broadcast, but not limited to this.
In the present embodiment, the configured information can be turn information, and navigation object is to the left or to the right as described in indicating
Turn to be returned on the direction of reference route；Can also be directional information, indicate as described in navigation object along West Nanjing Road to
Head west and sail etc. to be returned on the direction of reference route；Or information of place names is can also be, before indicating that the navigation object reaches
Four Seasons Hotel etc. at 500 meters of side is to be returned to the direction of reference route, but the configured information not limited to this.Configured information can
To guide navigation object to come back on the direction of the reference route (the AB straightways 00 in such as Fig. 2) in time, thus not
Navigation way must be recalculated, so as to reduce the amount of calculation of guider.
Further, as described in step S6, when the time parameter is more than second time threshold, based on the navigation
The current location information of object redefines navigation way with the destination.
In the present embodiment, specifically, now think that the navigation object much deviate from the reference route, at this
Plant under situation, if can on the direction of reference route by guiding user the navigation object is revert to again by configured information again
It can need to take a long time.
Therefore, in the present embodiment, when it is determined that the time parameter t is then led more than second time threshold according to
Navigate the current coordinate information on the electronic map of object and coordinate information weight of the destination on the electronic map
It is new to determine navigation way.In other words, as guider is by using the current location of the navigation object as starting point, with described
Destination (i.e. original destination B) is that terminal recalculates a bar navigation route.Wherein, the navigation way of recalculating
Process is known to the skilled person technology, will not be described here.
It should be noted that in actual applications, when the time parameter is more than very first time threshold value and is less than second
Between threshold value, guider will send configured information, and indicate that the navigation object will be revert on the direction of reference route.But if with
When family does not follow the guide of the configured information, it may result in the navigation object and further offset from the reference route
Direction, so that away from destination.Now, will be according to the current of the navigation object according to technical solution of the present invention guider
