20150039223 | NAVIGATION DEVICE AND SERVER DEVICE - An object of the present invention is to provide a navigation device and a server device that are able to calculate an optimal route reflecting the user's intention in a case where a new site is added after a route to a destination is set. The navigation device of the present invention includes a route calculation unit. The route calculation unit is configured such that, in a case where the predetermined site is newly designated and the route calculation unit needs to re-calculate a new route under a situation that an existing route to an existing destination has been already calculated, and in a case where a section that is divided by via points included in the existing route is also included in the new route, a predetermined calculation condition at a time of route calculation is also applied to the section of the new route, the predetermined calculation condition being applied to the section of the existing route, so that the calculation is performed in consideration of a change in a traveling order of traveling the existing destination or an existing via point included in the existing route. | 02-05-2015 |
