Described path-calculating element 12 can calculate described new guidance path according to the path chain at least, and described path chain is the road chain that filters out when calculating described current guidance path.Current guidance path runs into the front acquisition of blocking up, and has filtered out some path chains during calculating, if these path chains can avoid automobile to continue to block up, path-calculating element 12 can count these path chains when obtaining new guidance path.
The described mobile unit of the present embodiment can be when running into congestion, initiatively recomputate guidance path, obtained timely the new guidance path different from current guidance path in short time, improved the navigation efficient of mobile unit, and the mode that need not manually to input has guaranteed traffic safety.The raising of described navigation efficient comprises the generation time that has shortened guidance path, has begun in time new navigation.
As shown in Figure 2, the mobile unit of the embodiment of the present invention can also comprise: road conditions acquiring unit 13.Described road conditions acquiring unit 13 can be take second schedule time as interval timing acquisition real-time road condition information; Path-calculating element 12 calculates new guidance path based on the real-time road condition information that the last timing acquisition arrives at least.Described road conditions acquiring unit 13 can obtain real-time road condition information from external server.Described external server can be the private server of described mobile unit, can be also third-party server.Described second schedule time can be 3-5 minute.
Mobile unit can also comprise: time calculating unit 14.Described time calculating unit 14 can be at described average velocity during less than described threshold speed, calculates current time distance mistiming of timing acquisition real-time road condition information next time.Road conditions acquiring unit 13 is the timing acquisition real-time road condition information not only, also obtain immediately real-time road condition information at described average velocity less than described threshold speed and the half of not enough described second schedule time of described mistiming, path-calculating element 12 calculates described new guidance path based on the up-to-date real-time road condition information that gets at least.That is, the half of second schedule time of mistiming less than obtains real-time road condition information at once, and path-calculating element 12 calculates new guidance path based on this real-time road condition information that newly gets; The half that mistiming surpassed for second schedule time can not obtain real-time road condition information again, and path-calculating element 12 calculates new guidance path based on the real-time road condition information that the last timing acquisition arrives at least.So both can guarantee that the real-time road condition information that new guidance path uses when calculating upgraded in time, the communication resources that can avoid the real-time road condition information frequent updating to cause again take excessively.
Described road chain information can also comprise: road chain average velocity and road chain length.Do not consider in the situation of real-time road condition information, path-calculating element 12 can be according to road chain average velocity and road chain length obtain the to travel average required time of this road chain, then obtain to travel current location to the average required time in all paths of objective according to the average required time of every the road chain that travels, select the path of average required time minimum of driving path as guidance path.
Real-time road condition information can comprise real-time road chain average velocity.When path-calculating element 12 calculates new guidance path based on real-time road condition information at least, utilize road chain length and real-time road chain average velocity to calculate the average required time of this road chain that travels.The road chain average velocity of road chain or jogging road chain of blocking up is not identical with real-time road chain average velocity.
For example, current location has two to the path of objective, and article one path comprises: road chain number number is the road chain of link3 for the road chain of link1, road chain number for the road chain of link2 and road chain; The second path comprises: road chain number number is the road chain of link3 for the road chain of link1, road chain number for the road chain of link4 and road chain.Wherein, road chain number comprises for the road chain information of link1: road chain average velocity is that 10 meter per seconds and road chain length are 200 meters; Road chain number comprises for the road chain information of link2: road chain average velocity is that 16 meter per seconds and road chain length are 90 meters; Road chain number comprises for the road chain information of link3: road chain average velocity is that 22 meter per seconds and road chain length are 110 meters; Road chain number comprises for the road chain information of link4: road chain average velocity is that 5 meter per seconds and road chain length are 50 meters.
Do not consider in the situation of real-time road condition information, path-calculating element 12 obtain to travel road chain number is 20 seconds for the average required time of road chain of link1, the chain number of travelling is 5.625 seconds for the average required time of road chain of link2, the chain number of travelling is 5.625 seconds for the average required time of road chain of link2, and the chain number of travelling is 5 seconds for the average required time of road chain of link3; The road chain that travels number is 10 seconds for the road chain of link4 on average needs the time.Path-calculating element 12 is 36.625 according to the average required time of every road chain obtain the to travel average required time in article one path, and the average required time in the second path of travelling is 35 seconds.So in this situation, path-calculating element 12 can directly adopt the second path to navigate as the guidance path of current location to objective.
If real-time road condition information comprises: the road chain is number for the real-time road chain average velocity of link4 becomes 2 meter per seconds, path-calculating element 12 can according to road chain number for the road chain length of link4 be 50 meters and in real time road chain average velocity be that 2 meter per seconds acquisitions travel that number on average the needs time is 25 seconds to the road chain for the road chain of link4.Accordingly, path-calculating element 12 obtain the to travel average required time in second path becomes 50 seconds.So in this situation, path-calculating element 12 can directly adopt article one path to navigate as the guidance path of current location to objective.
