[0055](实施例4、导航装置的工作方法) [0055] (Example 4, the working method of a navigation device)

[0056] 见图5,本实施例的导航装置的工作方法中的导航装置,采用实施例3所得到的导航装置,该导航装置工作时包括如下步骤: [0056] Figure 5, the working method of the navigation device of the navigation device according to the present embodiment, the navigation device obtained in Example 3, comprising the steps of the navigation device operates:

[0057] ①在启动导航装置后,CPU单元1调出再运行程序数据库存储单元4中的导航主程序,而使CPU单元1处于不断接收GPS信号而计算出当前位置以及当前的行进速度的状态; 当由人工或系统对路径选择原则的优先次序和最接近的路口的距离的阈值进行选择,再由人工输入目的地点后,则引发CPU单元1调出再运行程序数据库存储单元4中的路径规划模块而计算出引导路径;CPU单元1计算出该引导路径后则在运行导航主程序的同时,从程序数据库存储单元4中调出再运行路线引导模块中的普通引导程序段,而按引导路径动态匹配从地图数据库存储单元3中取出的电子地图数据后进行实时导航:一是调出再运行程序数据库存储单元4中的地图显示模块,二是不断判断当前位置与引导路径上的前方的最接近的包括路口在内的提示点的距离是否达到所设定的阈值,三是判 [0057] ① after starting the navigation device, the CPU unit 1 to call up the main navigation run the program database storage unit 4, the CPU unit 1 in a state of constantly receiving a GPS signal and calculate the current position and the current traveling speed ; when the threshold distance manually or system selection principles path priorities and the closest intersection is selected, and then from the manual input destination point, the initiator CPU unit 1 to call path 4 run program database storage unit planning module calculates the guiding path; after the CPU unit 1 calculates the guide route navigation operation at the same time the main program, a database program transferred from the storage unit 4 run ordinary boot block route guidance module, and guided by the real-time dynamic matching route navigation map data taken from the map database in the storage unit 3: first run the program to call the map database in the storage unit 4 of the display module, the second is determined continuously on the front of the current position of the guide path the closest distance cue points, including junctions, including whether the threshold set, third sentence 车辆在行驶中是否偏离了上述引导路径; Running vehicle has deviated from the guidance route;

[0058] 若车辆在行驶中偏离上述引导路径,则CPU单元1重新调出再运行程序数据库存储单元4中的路径规划模块而计算出新的引导路径,然后调出再运行程序数据库存储单元4中的路线引导模块的普通引导程序段,按新计算出的引导路径进行实时导航。 [0058] When a running vehicle deviates from the guidance route, the CPU unit 1 recall the run the program database storage unit path planning module 4 calculates the new guide path and push the run the program database storage unit 4 the route guidance module ordinary boot block, calculated according to the new real-time navigation of the guide path.

[0059] ②步骤①中,在CPU单元1运行地图显示模块的过程中,先从地图数据库存储单元3中读取与当前位置相对应的电子地图数据,再将这些电子地图数据、车辆所处的位置数据以及引导路径的数据输送至显示单元7,显示单元7则在触摸显示屏上显示车辆当前所在位置、包括当前位置在内的电子地图以及相应的引导路径,且随着车辆的行进所显示的电子地图及引导路径做相应变动。 [0059] ② ① step, the unit operation in the CPU module 1 map display process, starting with a map database in the storage unit 3 reads the current position of the corresponding electronic map data, then the electronic map data, the vehicle in which the guidance route data and the position data conveyed to the display unit 7, the display unit 7 displays the location where the vehicle is currently on a touch screen, including the current location of the electronic map and including a respective guide path, and with the traveling of the vehicle electronic maps and route guidance display changes accordingly.

[0060] ③步骤①中,在CPU单元1运行路线引导模块中的普通引导程序段的过程中,当CPU单元1判断当前位置与引导路径上的前方最接近的路口的距离为设定阈值或小于设定阈值(本实施例为200米,其他实施例中可以是100、150、300或400米等)时,则CPU单元1从与引导路径相匹配的电子地图数据中读取该路口的模型编号的地址码,再由该地址码从地图数据库存储单元3中读取该路口的模型编号;对该模型编号进行识别后,而判断该路口是简单路口还是复杂路口;若是复杂路口则在运行路线引导模块的普通引导程序段的同时,从程序数据库存储单元4中调出再运行路线引导模块的路口引导程序段:根据引导路径通过该复杂路口时的行驶路线,而得到进入路口的道路的编号和离开路口的道路的编号,将这两个编号进行组合后则得到了附加编号,从而也就得到了本次 [0060] ③ step ①, the normal boot process block in the CPU unit to run a route guidance module in the CPU unit 1 determines when the distance forward of the current position of the intersection closest to the guidance route to the set threshold or less than a set threshold value (200 m in this embodiment, other embodiments may be 100,150,300 or 400 meters, etc.), then the CPU unit 1 reads the intersection data from the electronic map and guidance route that matches the model number address code, and then read by the address code from the storage unit 3 in the map database model number of the intersection; after identifying the model number, and determines whether the intersection is a simple or complex intersection junctions; complicated if at junctions while block general booting operation of route guidance module, transferred from the program database storage unit 4 and then running route guidance module intersection boot block: the guidance route through the traveling route when the complex intersection, to give a road entering the intersection of the number and exit the intersection of the road number, after combining the two numbers to get the additional numbers and, thus, get this 驶通过该复杂路口的总编号。 The total number of the drive through the complex intersection. 所述设定阈值可根据不同的道路类型而采用不同的值,例如在普通公路上为150米,在高速公路上为400米;也可以由用户设定。 The set threshold value may be different depending on the type of road, ordinary road, for example, 150 m, 400 m on the highway; may be set by the user. 当两个路口之间的距离小于设定阈值时,因为程序设定导航装置只对前方最接近的路口的距离用设定阈值进行对比,即便前方非最接近路口的距离也等于或小于设定阈值,CPU单元1也不会对此进行理睬。 When the distance between the two intersections is smaller than the set threshold, the navigation device programmed because only the closest distance in front of the intersection are compared with the threshold value, even if the distance in front of the closest non-junction is also equal to or less than a set threshold value, CPU section 1 not conduct ignored. 但是若车辆一旦通过当前路口,则此时在前方存在距离小于设定阈值的路口的情况下,才即刻对该路口运行路线弓I导模块的路口引导程序段。 However, in the case when the vehicle once the current through the junction, intersection exists at this time distance is smaller than the set threshold at the front, immediately before the guide intersection crossing the path of travel block I bow guide module.

[0061] ④步骤③中,在CPU单元1运行路线引导模块的路口引导程序段而判断前方最接近路口为复杂路口,然后得到了复杂路口的模型编号和表示通过路口的行驶路线的总编号的情况下, [0061] ④ step ③, the unit is operating in the CPU module 1 route guidance intersection in front of the guide block closest to the intersection is judged as a complex intersection and the complex intersection to give the model number and the total number is represented by the intersection of the travel route the case,

[0062] 一方面CPU单元1继续运行地图显示模块而使显示单元7的触摸显示屏显示车辆当前所在位置以及包括当前位置在内的电子地图以及引导路径,同时继续运行路线引导模块的路口引导程序段,而根据模型编号在复杂路口模型库中调出该复杂路口模型的标注有道路编号的路口图案数据,根据总编号在复杂路口模型库中调出相应的箭头图案数据,再将这些调出的数据输至显示单元7的显示屏,在触摸显示屏上叠加显示标注有道路编号的路口图案,以及在该路口图案上叠加显示表示行驶路线的箭头图案。 [0062] In one aspect the CPU unit 1 continues to operate the map display module touch screen display unit 7 to display the current location of the vehicle and comprising an electronic map including the current location and a guide route, while continuing to run the route guidance intersection guidance program modules section, while crossing the road number pattern data according to the model number to call this model the complex intersection model library labeled complex intersection, based on the total number of complex modulation intersection model library pattern data corresponding arrows, then the recall the data input to the display unit 7 is a display screen, the touch screen display is superimposed on the road number of intersections marked with a pattern, and the crossing pattern is superimposed on the travel route represented by an arrow display pattern.
