Looking for the third picture, first, the acquisition-guide path (step (10), succeeding in extracting the electronic map from an electronic map database (step 320), ^ and the electronic map to obtain the turn information, wherein each turn information is Γ丨Direction (step 33Q), and calculate the distance between the current position and the closest, number (ie, closest to the current position) (step 340), and the outer ^^^^〇fL) to - comparison result = distance _ - the established range is compared with the pair, in order to obtain (the first step 350), according to the comparison result and the direction of the subject, the first 13 1280403 my brother trigger signal, so that the first or second indicator light emits light in response to the trigger signal (γ) Step: > 60), wherein each electronic map includes a number of relevant features of the map features, such as road shapes, road names, road intersections, attributes, two-dimensional coordinates or other related traffic information, etc. Step 310", the guiding path is the shortest line from the starting point to the destination obtained according to the starting point and destination selected by the user and the electronic map, and the L-way can's According to the destination selected by the user, • The current position (ie, the current position detected) and the electronic map to obtain the shortest travel distance from the starting point to the destination. Here, the user can input through various human-machine interfaces. The starting point and destination of the travel. The current position is detected by a positioning module according to the satellite signal; here, the positioning module can be Z-GPS receiver. , \... in "Step 360" For convenience of explanation, it is assumed that the first and second trigger signals respectively correspond to the guiding directions of the left turn and the right turn, and the first and second indicator lights are illuminated by the first and second trigger signals. The fourth item, when the distance = into Wei Ding Fancai and the direction of the correction is left turn, send (four) - riding signal (4 362), so that the _ indicator light shines in response to the first trigger signal, and then does not use The user will turn left to the message (step 372); in addition, when the calculated distance range and the guiding direction is right turn, the second touch _ sudden collapse is issued, and the second indication is turned _ two_峨 secret light, and then lift the purpose of the right turn message (step 374); however When the calculated distance is not within the established range, no trigger signal is issued. 14 1280403 Although the preferred practice of the present invention is as described above, the invention of the present invention, any _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Enclosed in this specification, the application for patents _ define the scales.干 围 【 图 图 图 面 面 面 面 面 面 面 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要 概要A schematic diagram of the appearance of a navigation system of a navigation device of an embodiment; and a schematic diagram of a navigation system having a device according to another embodiment of the present invention; (10) a direction flow chart; And FIG. 3 is a diagram showing the method of prompting the navigation direction of the present invention.
