In the method for the present invention, personal navigation apparatus first cooks up some bar navigation paths of current position to point of destination according to the algorithm (algorithm) preset. Personal navigation apparatus, according to the point of interest on some bar navigation paths of planning, calculates the weight in this some bar navigation path. For example, if a default point of interest is present on one first guidance path in this some bar navigation path, personal navigation apparatus adjusts the weight of the first guidance path.Personal navigation apparatus can set different point of interest of presetting to the influence degree of the weight of the guidance path that personal navigation apparatus is planned, the mark of this influence degree and each point of interest, and the method for the present invention is according to the mark of the point of interest on some bar navigation paths of planning, calculate/adjust the weight in some bar navigation paths. Personal navigation apparatus is again according to the weight in some bar navigation paths, therefrom selecting a guidance path to navigate user to point of destination from current position, such as personal navigation apparatus can select a guidance path with highest weighting (or having other grade such as the guidance path of the weight of minimum or intermediate value) with the user that navigates from some bar navigation paths of planning. Owing to personal navigation apparatus first can cook up some bar navigation paths according to the algorithm preset, more therefrom adjustment has the weight of the guidance path of default point of interest. Therefore, when user is directed through the guidance path of default point of interest by the method for the present invention, the sensation on user You Rao road can't be allowed.
Please refer to Fig. 2. Fig. 2 is that the method for the present invention is according to the schematic diagram of weight of the point of interest adjustment guidance path on guidance path. As shown in Figure 2, when user is for going to a point of destination B from a starting point A, personal navigation apparatus draws guidance path R1 and R2 according to the algorithm rule preset. Assume that personal navigation apparatus stores one and presets point of interest M, such as McDonald. When personal navigation apparatus judges to there is a McDonald branch on guidance path R2, the weight of personal navigation apparatus adjustment guidance path R2, to select guidance path R2 and be supplied to user, so that user is navigated to point of destination B from starting point A, and user can through presetting point of interest M and McDonald in guidance path R2 way.
Some bar navigation paths that the method for the present invention is planned can comprise some different default points of interest. Personal navigation apparatus can according to different default points of interest, the weight of the different guidance path presetting point of interest place of adjustment to some extent. Please refer to Fig. 3. Fig. 3 is the schematic diagram that the method for the present invention carrys out the weight of corresponding adjustment guidance path according to different point of interest. Assuming that personal navigation apparatus stores two and presets point of interest M, K, for example, presetting point of interest M is McDonald, and default point of interest K is KFC. The weight correspondence of the guidance path at default point of interest M, K place is made adjustment in various degree by personal navigation apparatus respectively; For example, the weight of the guidance path at default point of interest M place is increased " 7 " individual unit by personal navigation apparatus, and the weight of the guidance path at default point of interest K place is increased " 5 " individual unit. As shown in Figure 3, when user is for going to a point of destination B from a starting point A, personal navigation apparatus first draws guidance path R1 and R2 according to the algorithm rule preset. When personal navigation apparatus judges to there is a KFC branch (namely presetting point of interest K) on guidance path R1, and when there is a McDonald branch (namely presetting point of interest M) on guidance path R2, personal navigation apparatus adjusts the weight of guidance path R1, R2 respectively simultaneously. For example, the weight of the guidance path R1 at KFC branch (namely presetting point of interest K) place is increased " 5 " individual unit by personal navigation apparatus, and the weight of the guidance path R2 at McDonald branch (namely presetting point of interest M) place is increased " 7 " individual unit. In the present embodiment, personal navigation apparatus selection one from some bar navigation paths of planning has the guidance path of highest weighting with the user that navigates; " 5 " individual unit is added and the weight of guidance path R2 adds " 7 " individual unit due to the weight of guidance path R1, therefore, personal navigation apparatus provides guidance path R2 to user, so that user is navigated to point of destination B from starting point A, and user can through particular point of interest M and McDonald in guidance path R2 way.
In another embodiment of the present invention, personal navigation apparatus also simultaneously according to the category of roads of the point of interest (mark of such as point of interest) on some bar navigation paths of planning and this some bar navigation path, can calculate the weight in this some bar navigation path.
