The method according to this invention can be effectively determined the road of one or more snippets obstruction of existing in road ahead in the process of moving, and the whole jam situation of road.
Fig. 2 has illustrated the method flow diagram that a kind of congestion information that obtains according to the present invention navigates, and wherein, described method comprises step S8, step S9, step S10, step S11 and step S12.
In step S8, when satisfying trigger condition, navigator is according to described whole traffic information and described route guidance information and executing analysis operation, to obtain congestion information.
Wherein, described trigger condition comprise following any:
1) schedule time condition; For example, trigger execution every the schedule time.
2) predetermined instruction condition; That is when receiving user instruction executable operations.For example, when receiving user's request.
3) scheduled event trigger condition, that is when scheduled event occurs trigger action.For example, when traffic information is updated, again for example, when this mileage during greater than predetermined mileage threshold value etc.
Wherein, described congestion information comprises whole congestion information and one or more navigation congestion information.
Wherein, the mode of obtaining navigation congestion information and whole congestion information is described in detail in aforementioned reference embodiment shown in Figure 1 and preferred embodiment thereof, and is contained in this by reference, repeats no more.
Then, in step S9, when described congestion information satisfies predetermined acceleration environment, the described congestion information of navigator prompting.Wherein said predetermined acceleration environment is used for judging the current acceleration operation of again planning navigation way of whether can carrying out.
Wherein, described predetermined acceleration environment comprise following any:
When 1) the corresponding highway section that blocks up of navigation congestion information can be evaded;
2) when having whole congestion information.
Preferably, this moment, described navigator also was provided for obtaining the function of the navigation way of acceleration to the user.
For example, present the information of " the place ahead XXX kilometer is found the XXX rice highway section that blocks up to click and to attempt accelerating " to the user, and the action button corresponding with " acceleration " function in this information is provided, select for the user.
Then, in step S10, navigator waits for that the user is based on the command information of described congestion information.
Preferably, navigator waits for that in the given time the user gives the command information of described congestion information.
In step S11, after receiving described user instruction information, again plan navigation way based on described congestion information.

In step S12, navigator provides the described navigation way of planning again to the user.
Preferably, described navigator is also pointed out this information such as time that navigation way of again planning is saved with respect to former navigation way to the user.
Then, after navigator is completed the operation that this time plan again, restart to detect whether satisfy preset trigger condition, to determine whether restarting execution in step S9 to step S12.
During Fig. 8 a had illustrated according to one embodiment of present invention, navigator and user carried out mutual a plurality of states.
Under normal condition, navigator detects whether satisfy preset trigger condition, and when satisfying preset trigger condition, according to described whole traffic information and described route guidance information and executing analysis operation, to obtain congestion information.
For example, when detecting when travelling the schedule time, initiatively execution analysis operates to obtain congestion information, again for example, when receiving user instruction, responds this user instruction and comes execution analysis to operate to obtain congestion information.
When described congestion information satisfies predetermined acceleration environment, change alert state over to, point out this congestion information to the user.And change waiting status over to, wait for the command information that receives the user.
After receiving described user instruction information, change acceleration mode over to, again to plan navigation way according to described congestion information.
After the navigation way that obtains planning again, change the acceleration completion status over to, provide this navigation way to the user, and come back to normal condition.
When waiting status failed to receive in the given time user instruction information, navigator changed normal condition over to when navigator, again detected the current trigger condition that whether satisfies.
One of according to a preferred embodiment of the invention, when not satisfying described predetermined acceleration environment, described navigator is pointed out other information, and restarts to detect whether satisfy preset trigger condition.
For example, comprise the navigation congestion information in the congestion information that obtains, and road corresponding to this navigation congestion information be can't get around the time, navigator determines that this congestion information does not satisfy predetermined acceleration environment, and points out current jam situation.
Again for example, current when being in navigation congestion information corresponding jam road, determine that it does not satisfy predetermined acceleration environment, and point out current jam situation.
Fig. 8 b has illustrated that the navigator corresponding with the preferred embodiment and user carry out mutual a plurality of state conversion process.
In a plurality of states of Fig. 8 b, alert state comprises the first alert state and two sub-states of the second alert state.
When described congestion information satisfies predetermined acceleration environment, change the first alert state over to from normal condition, point out this congestion information and executable operation thereof to the user.
Otherwise change the second alert state over to, point out congestion information to the user, and get back to normal condition.
If do not receive the user about accelerating the instruction of operation in the first alert state, change waiting status over to, continue to wait for user's operation.
If receive the user about accelerating the instruction of operation in the first alert state or in waiting status, change acceleration mode over to, again plan navigation way according to described congestion information.
The method according to this invention can plan again that for the user navigation way is regional to dodge this obstruction according to the congestion information of determined road ahead, and the probability of waiting for is stopped up in minimizing, improves the efficient of driving a vehicle.
Fig. 3 has illustrated that a kind of congestion information based on calculating provides the method flow diagram of navigation information.Wherein, described method comprises step S13, step S14 and step S15.
