Problems solved by technology

However, if the actual destination of the vehicle is not the same as the predicted destination of the server, especially when the direction of the two is very different, the diversion point information may not be helpful for vehicle driving
Moreover, although the existing standard traffic information provides information on diversion points, there are many paths through these diversion points, and the existing standard traffic information does not provide corresponding route exploration and best route suggestions

Embodiment 1

[0083] The following is attached Figure 4 The navigation process performed by the navigation device of the present invention will be described. Figure 4 It is a flowchart of Embodiment 1 of the navigation apparatus of this invention.

[0084] After starting the navigation device, first, the current position detecting device 33 detects the current position of the vehicle (step 101). Then enter step 102, input the destination. Specifically, the driver enters the destination setting menu on the display of the navigation device, and inputs the destination through the destination input device 34 . The input method can be input by typing on the user's touch screen or remote controller, or by selecting input from an existing list on the display. Then, in step 103, the route searching device 35 calculates the route to the destination according to the input destination and the map data stored in the storage device, and obtains the current guiding route. And in step 104, start pat...

Embodiment 2

[0099] In Embodiment 1, a new guiding route is recalculated according to the distribution point information provided by the server. However, for the same congested road section, there may be multiple predicted destinations provided by the server, and there may be multiple diversion points, so there may be multiple diversion paths through these multiple diversion points.

[0100] Figure 8 A schematic diagram showing a guide route according to Embodiment 2 of the present invention. exist Figure 8 , assuming that the current position of the vehicle is A and the destination is D, there are two predicted destinations for the acquired congestion information (black thick line in the figure): O1 and O2, and the diversion points are B1, B2, B3 and B4 respectively . The route to destination D may pass through B1, B2, or B1, B2, B3. Thus, there may be multiple recalculated guidance paths, so it needs to be determined how to select these guidance paths. In this embodiment, the guid...

Embodiment 3

[0112] The following is attached Figure 10 , 11 Embodiment 3 of the present invention will be described.

[0113] In this embodiment, there are multiple traffic information received from the server, that is, there are multiple predicted destinations. As for how to use the diversion point information, this embodiment uses at least one diversion point information contained in multiple traffic information. .

[0114] Figure 10 A schematic diagram showing a guide route according to Embodiment 3 of the present invention. like Figure 10 As shown, assume that the current position of the vehicle is A, the destination is D, and there are two predicted destinations: O1 and O2, where the diversion points passed by the predicted destination O1 are B1, B2, B3, and B4 respectively; The distribution points passed by the destination O2 are respectively B1, B2, B3, and B5. In this embodiment, two diversion points ( B1 , B2 ) commonly included in the two predicted destinations are used...

Abstract

The invention provides a navigation device capable of effectively keeping away from congestion road sections or prohibition road sections according to traffic information provided by a server to improve running efficiency. The navigation device comprises a display device, an information acquiring device and a control device, wherein the display device is used for displaying road maps around a car position; the information acquiring device is used for acquiring the traffic information comprising a forecasted destination, the positions of congested places or running-prohibited places and shunting points for bypassing the congested places or the running-prohibited places; and the control device is used for searching a new running track when the positions of the congested places or the running-prohibited places are on the set running tracks and the position of the forecasted destination accords with the traffic information of the destination direction from the current position so that the new running track passes through the shunting points.

Description

field of invention [0001] The present invention relates to a navigation device and a route search method of the navigation device, in particular to a navigation device and a route search method of the navigation device which can correctly detour to a congested place and a travel-restricted place and explore a walking route that can reach a destination. Background technique [0002] In recent years, with the advancement of digital technology, various technologies have been developed to improve the convenience of automobiles. For example, according to the current location and driving direction of each vehicle that can communicate wirelessly with the server, the server predicts the destination of each vehicle, and sends different driving advice information (such as diverting traffic) to each vehicle facing the same predicted destination direction. Suggestion information), so that these vehicles do not concentrate on one road, thus achieving the purpose of alleviating traffic ja...
