In the technical scheme, in the navigation moving process of multi-screen terminal 600, by the position for calculating multi-screen terminal 600The time spent with the mobile distance with the distance between starting point of navigating is put, the translational speed of multi-screen terminal 600 is determined.IfIn the predetermined period of the renewal navigation information determined according to navigation way, detect the translational speed of multi-screen terminal 600 more than etc.When default translational speed, reduce and the moment for updating navigation information next time is determined after the predetermined period, detect multi-screen endHold 600 translational speeds be less than default translational speed when, increase determine after the predetermined period next time update navigation information whenCarve.So, according to the translational speed of multi-screen terminal 600 time for updating navigation information is increased or is reduced, can be morePredetermined period is reasonably adjusted, such as in the case of traffic congestion, vehicle mounted guidance is updated always to navigation way, it is not necessary that pressNavigation information is updated according to predetermined period, flow is in turn resulted in and is wasted and power consumption penalty, therefore in translational speed more than default movementDuring speed, reduce and the moment for updating navigation information next time is determined after predetermined period, when translational speed is less than default translational speed,The moment for updating navigation information next time is determined after increase predetermined period.
Locating module 606 is additionally operable to：Matching degree between detection motion track and navigation way；Detecting motion trackWhen matching degree between navigation way is spent less than or equal to preset matching, information is generated, to prompt the user whether adjustmentNavigation way.
In the technical scheme, if detecting the movement between the position of multi-screen terminal 600 and the starting point of navigation wayTrack will reduce departing from the matching degree between navigation way, with navigation way, if decreased below equal to preset matchingDegree, then generate information, to prompt the user whether to adjust navigation way, according to the current location of multi-screen terminal 600 and leads againBoat terminal generates navigation way.So, road is changed if as occurring in that fortuitous event or user's reason in navigation wayLine, can in time remind whether user changes navigation way, to improve the experience of user.
Locating module 606 is additionally operable to：When the positional information for detecting multi-screen terminal 600 overlaps with navigation terminal, extinguishInk screen 604.
In the technical scheme, if the positional information for detecting multi-screen terminal 600 overlaps with navigation terminal, then it is assumed that thisWhen user have arrived at destination, now navigation terminates, and extinguishes the navigation information shown on ink screen 604, and ink is closed in timeScreen 604, reduces the power consumption penalty of multi-screen terminal 600.
