Navigation devices, methods, and programs set a destination, find an on-street parking zone that is in the vicinity of the destination, and find a route, by modifying a search cost for a road, that will arrive at the destination by way of a road having the on-street parking zone. The devices, methods, and programs acquire parking information that pertains to the on-street parking zone and find the route by modifying the search cost based on the parking information. The devices, methods, and programs find the route when the vehicle has reached a specified distance from the destination.

Navigation devices, methods and programs

A method is provided, for manufacturing a stator for a rotary electric machine by shrink-fitting an outer cylinder to a core assembly where a cage-shaped wound coil is assembled with segment cores. The assembly is inserted into the outer cylinder having a diameter increased by thermal expansion caused by the heat from a heating unit, while the outer diameter of the assembly is being reduced by permitting the assembly to pass through a tapered guide unit. The guide unit has a portion whose diameter is larger than an outer diameter of the assembly, and a portion whose diameter is larger than an inner diameter of the outer cylinder and smaller than an inner diameter of the cylinder in the thermally expanded state, and a tapered through hole vertically passing through the guide unit. Thus, the size of the assembly is radially reduced, with a uniform diameter being obtained throughout the assembly.

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.

In a multi-phase rotary electric machine, each of phase windings is composed of a pair of semi-phase-windings having a starting end portion, a plurality of series-connected wave-coil units, and a connecting end. Each of the wave-coil units is composed of a pair of in-slot-portions and a pair of crossing portions. One of the pair of semi-phase-windings is disposed on top of the other in the radial direction in the same slots, thereby forming a pair of coils each the magnetic pole. Each of the crossing portions of one of the pair of semi-phase-windings has a flat U-shaped-folded-portion disposed on top of one of the crossing portion of the other in the radial direction so that the U-shaped-folded-portions of the pair of semi-phase-winding can be aligned in the radial direction.

Lane change guidance information is output based on data for the next guide intersection on a route calculated in advance and on detection of the driving lane in which the vehicle is currently driven. The system includes present position detection, direction of advance determination for guide intersections along the preset route, driving lane determination, and guidance information output for instructing the driver when direction to be taken at a guide intersection does not match the current driving lane, whereby adequate guidance information is provided the driver regarding lane changes when the vehicle is driven on a road having two or more lanes.

Navigation system for vehicles

A structure configuration map display system includes a controller for depicting and displaying a structure configuration map based on structure configuration map information. The system provides for searching and guidance relative to a structure designated as a target point. A display form corresponding to the structure information for the target point is determined and the display form of the target point is changed based on the results of that determination and is displayed so that a user can easily recognize the desired facility by its display form which corresponds to stored structure information. Also, the user can easily identify a facility as the desired facility and can obtain reliable guidance to that target point by the display form which indicates the type of the structure.

Information guidance system based on structure configuration map

In a navigation apparatus for a vehicle, after the present position of a vehicle is obtained, a position on a map which corresponds to the present position of the vehicle is obtained. Subsequently, the heading direction of the vehicle is detected. When the vehicle is traveling on the left-hand lane, coordinate conversion is performed such that a present position mark is shifted leftward from the center of the road by 1/4 of the road width. This makes it possible to display a route while preventing the route from overlapping with the centerline of the road. In another navigation apparatus for a vehicle, a structure-profiled map on which a structure-representing shape and a road are drawn is displayed so as to provide road guidance, wherein a route is displayed on the structure-profiled map along a road which is displayed for guidance. The display of the route is performed such that the route is shifted from the center line of a road toward a lane on which the vehicle is traveling. The route is displayed by using a pattern having a width corresponding to the width of the road in accordance with the lane of the road to be guided.

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.

Road or other guidance is provided by displaying a structure-shape map showing building shapes and roads. Drawing of building shapes on the map is restricted according to a specific condition, e.g. the travel condition of the vehicle, or the screen scroll mode, by setting the display color for building shapes to the same color as that for a background, or by not drawing any of them, thereby preventing the screen from becoming difficult to see even during scrolling. For the structure-shape map, a storage device (3) stores map data having a name and a coordinate string for each shape of various structures and information belonging to each structure. A guidance controller (4) decides colors, color densities, patterns thereof, etc. for shapes as display modes on the basis of information belonging to the structures, e.g. the classification and height of each structure, and other detailed information (e.g. scale of construction), retrieves information belonging to a structure concerned, together with information regarding surroundings, and displays, on a display (12), shapes and names according to the decided display modes, thereby giving guidance. The structure-shape map may be displayed centered on a structure having a telephone number retrieved by entry of the telephone number.

Navigation system for displaying a structure-shape map

Upon recognizing the shapes of buildings or facilities, the buildings or facilities can be identified and destinations can be designated simply and easily. The display of a house map and a road map is changed over depending upon predetermined conditions. This makes it easy to navigate to the destination. When the destination is shown on the house map, a guide route is identified on a road adjacent to the building at the destination. This makes it easy to see where in the vicinity of the destination the car arrives.

Map indication device and navigation device

An alternating current generator for a motor vehicle includes magnet type field cores, i.e., field cores with claw poles on which permanent magnets are interposed in the spaces between the claw poles, where the generator has a ratio of number of claw poles/outside diameter of the field core that allows generation of a large output current. The alternating current generator includes permanent magnets disposed in spaces between peripherally adjacent claws which reduce the magnetic flux leakage caused by the field coil occurring in the spaces. When a residual magnetic flux density higher than 0.25 tesla is applied in advance in a direction that reduces magnetic flux, a large output current is obtained when the above-noted ratio is in the range of from about 1.6.times.10.sup.-1 to 2.0.times.10.sup.-1 (1/mm).
