摘要： A navigation apparatus reduces route search time while providing guidance in conformity with drivers' preferences, by selectively conducting either a full-range route search or a more limited, local area search, in accordance with detected conditions and responsive to occurrence of an off-route event. For example, the full-range route search is conducted pursuant to a determination that the vehicle has gone straight at a predetermined number of certain intersections where current guidance has directed a turn.
摘要翻译：导航装置通过根据检测到的条件选择性地执行全范围路线搜索或更有限的局域搜索，并根据驾驶员偏好的出现来减少路线搜索时间，同时提供与驾驶员偏好相关的指导。事件。例如，全程路径搜索是根据车辆在当前引导已经转向的某个交叉点的预定数量已经直线的确定进行的。

摘要： A navigation apparatus has an input unit (1), a CPU (2), a display unit (3) and a memory unit (4), the memory unit (4) being a memory such as a CD-ROM in which network data of geographical points, namely destinations and present locations, and information are stored in advance. Also stored are map data (10), an intersection list (11), a destination list (12), road data (13) and a region name list (14), etc. When a destination is designated by an input from the input means (1), the CPU (2) performs an exchange with a program, stored in a ROM (9a), in order to set information for travel to the destination by course exploration in accordance with each geographical point stored in the memory unit (4). This information is stored in a memory such as a RAM (9b). In an embodiment, the RAM (9b) is provided with a non-volatile area for storing departure-point data (east longitude, north latitude, etc.). When an input is made by a reset switch in entering a departure point, the data in this non-volatile area can be rewritten. Data written in are preserved until the reset switch is pressed again and a geographical point is entered. Data will not be erased even if an ignition switch is turned off.
摘要翻译：导航装置具有输入单元（1），CPU（2），显示单元（3）和存储单元（4），存储单元（4）是诸如CD-ROM的存储器，其中网络数据的地理位置，即目的地和当前位置，并且预先存储信息。还存储地图数据（10），交叉路口列表（11），目的地列表（12），道路数据（13）和区域名称列表（14）等。当通过输入的输入指定目的地时（1）中，CPU（2）执行与存储在ROM（9a）中的程序的交换，以便根据存储在存储单元中的每个地理位置通过课程探索设置到目的地的旅行信息（ 4）。该信息存储在诸如RAM（9b）的存储器中。在一个实施例中，RAM（9b）设置有用于存储起点数据（东经，北纬等）的非易失性区域。当输入起点的复位开关进行输入时，可以重写该非易失性区域中的数据。写入的数据将保留，直到再次按下复位开关并输入地理点。即使点火开关关闭，数据也不会被擦除。

摘要： A navigation system provides road guidance by displaying information relating to roads on a structure shape map, together with landmark information, in such a manner that only information around the present position is highlighted. The system retrieves road information in the direction of travel from the present position according to the vehicle speed, or road information within a predetermined angular or distance range in the direction of travel. Information relating to roads includes information indicating a one-way road, information indicating a road into which entry is prohibited, and information indicating a pedestrian crossing and a railroad crossing. These items of information are displayed by using marks, and the landmark information is displayed by using landmarks, thereby displaying information necessary for travel in a readily perceivable manner according to the travel conditions. When the vehicle enters a parking lot in the middle of the guidance for a route to a destination, the system searches for a route from the parking lot to the destination and outputs the found route by using a structure-shape map. The parking lot in this case is one within a predetermined walking distance from the destination. If the parking lot is in close proximity of the destination, further guidance is not necessary and the guidance is terminated.
摘要翻译：导航系统通过在结构形状图上显示与道路相关的信息以及地标信息，以仅使当前位置周围的信息突出显示的方式来提供道路引导。该系统根据车速，或行进方向上的预定角度或距离范围内的道路信息，从当前位置的行进方向检索道路信息。与道路有关的信息包括指示单行道路的信息，表示禁止入境的道路的信息，以及表示行人过路处和铁路道口的信息。通过使用标记显示这些信息项，并且通过使用地标显示地标信息，从而根据行驶条件以容易察觉的方式显示行驶所需的信息。当车辆在到目的地的路线的引导中间进入停车场时，系统搜索从停车场到目的地的路线，并通过使用结构形状图输出找到的路线。这种情况下的停车场是距目的地预定步行距离内的停车场。如果停车场靠近目的地，则不需要进一步的指导，并且指导终止。

摘要： In a navigation system, user preferred road data is determined and stored during travel to supplement fixed road data such as map data, intersection data, node data, and destination data stored in CD-ROM for subsequent use in providing route guidance in accordance with user road preferences. The user preferred road data is the data of actual trips, and the preference of the user is reflected in the user preferred road data. To determine user preferences, either the user preferred road data is compared to the fixed road data or a searched route calculated from the user preferred road data and CD-ROM data is compared with the searched route calculated from CD-ROM data. By using the determined user preferences in route searching, it is possible to provide more elaborate route searching and route guidance in accordance with the preference of the user.
摘要翻译：在导航系统中，在旅行期间确定并存储用户优选的道路数据，以补充诸如地图数据，交叉路口数据，节点数据和存储在CD-ROM中的目的地数据之类的固定道路数据，用于随后用于根据用户提供路线引导道路偏好。用户优选的道路数据是实际旅行的数据，并且用户的偏好被反映在用户偏好的道路数据中。为了确定用户偏好，将用户优选道路数据与固定道路数据或从用户优选道路数据计算的搜索路线进行比较，并将CD-ROM数据与从CD-ROM数据计算的搜索路线进行比较。通过在路由搜索中使用确定的用户偏好，可以根据用户的偏好来提供更复杂的路由搜索和路由引导。

摘要： A navigation system calculates a route from a present position of a vehicle to a destination and provides guidance based on the calculated route. When the vehicle is within a given distance from a next approaching branch point requiring guidance, branch points existing within a given distance from next approaching branch point are determined and direction information for the branch points is acquired. The acquired direction information is compared with direction information at the next approaching branch point, and a common direction information is displayed based on the result of the comparison. Also, the navigation system according to the present invention detects a name of an interchange where the vehicle is to exit from the course and a distance to said interchange based on the present position of the vehicle in case the road where the vehicle is currently driven along is an expressway or a toll road. The navigation system according to the present invention calculates a route from the present position to the destination and properly calculates and provides guidance for the expected time of arrival at the destination as the vehicle moves.

摘要： A vehicle navigation system includes a simulated run mode along with a normal navigation mode. In the simulated run mode, a simulated present position is calculated to move in accordance with simulated motion so that route guidance information is presented to the viewer in the same manner as during actual navigation. The simulated motion may be increased or decreased, may be stepped or continuous, and/or may be controlled in accordance with stored speed information on the roads of the route.

摘要： A navigation system including a present-position sensing system for sensing a present position; information storage medium for storing map information; an input device for entering into the system the destination, a roundabout point, a bypass, and the location desired to be traversed for entry of input indicating the execution of a route search from the present position sensed by the present-position sensing system to the destination; an output device for outputting information route guidance; and a central processing unit including a route searching capability for searching for a route to the destination; a route storage capability for provisionally storing the identified route; and route guidance control for sending a signal for performing route guidance to the output device. When the roundabout point or bypass is entered in the system, a search cost for roads and intersections near to the roundabout point or bypass is raised so that route search processing can be performed. When the location desired to be traversed is set, roads near to the location desired to be traversed are retrieved for search purposes. In travel guidance, a present-position mark is displayed in either a continuous mode or a blinking mode depending on the state of travel.

摘要： A vehicular navigation system includes: a current position detection unit for detecting the current position of the vehicle; an information storage unit for storing map information for conducting route searching and for providing route guidance; an input unit for inputting a destination and inputting instructions for executing a search of the map information for a route from the current position detected by the current position detection unit to the destination; an output unit for outputting information for route guidance; and a central processing unit for temporarily memorizing a route detected by the route search and for outputting a signal to the output unit to provide route guidance according to the memorized route. The central processing unit judges whether or not one information storage unit has been replaced by another and, when replaced, if the destination has not been reached, conducts another route search from the current position to the destination.
