  Next, a basic operation of the navigation system having the above configuration will be described.

  First, when the operation unit 34 is operated by the driver and the navigation device 14 is activated, a current location reading processing unit (not shown) of the CPU 31 performs current location reading processing, and the vehicle position and the vehicle detected by the GPS sensor 15 are detected. Read direction. Next, the matching processing means (not shown) of the CPU 31 performs matching processing, based on the trajectory of the read vehicle position and the shape, arrangement, etc. of each road link constituting the road around the vehicle position, The vehicle position is specified by determining on which road link the vehicle is located.

  Subsequently, a basic information acquisition processing unit (not shown) of the CPU 31 performs a basic information acquisition process and acquires the map data by reading it from the data recording unit 16 or receiving it from the information center 51 or the like via the communication unit 38. And get. In addition, when acquiring map data from the information center 51 etc., the said basic information acquisition process means downloads the received map data to the said flash memory.

  A display processing unit (not shown) of the CPU 31 performs display processing and forms various screens on the display unit 35. For example, the map display processing unit of the display processing unit performs a map display process, forms a map screen on the display unit 35, and displays a surrounding map, a vehicle position and a vehicle direction on the map screen.

  Therefore, the driver can drive the vehicle according to the map, the vehicle position and the vehicle direction displayed on the display unit 35.

  Further, when the driver operates the operation unit 34 to input a destination, a destination setting processing unit (not shown) of the CPU 31 performs a destination setting process to set the destination. If necessary, the departure place can be input and set. It is also possible to register a predetermined point in advance and set the registered point as a destination. Subsequently, when the driver operates the operation unit 34 to input a search condition, a search condition setting processing unit (not shown) of the CPU 31 performs a search condition setting process to set the search condition.

  When the destination and search conditions are set in this way, the route search processing means (not shown) of the CPU 31 performs route search processing and reads the vehicle position, vehicle direction, destination, search conditions, etc. The search data is read from the data recording unit 16, and the route from the departure point to the destination represented by the vehicle position is searched based on the vehicle condition, vehicle direction, destination, search condition, etc. And route data representing the searched route is output. At this time, the route with the smallest total link cost assigned to each road link is set as the searched route.

  The information center 51 can perform a route search process. In that case, the CPU 31 transmits the vehicle position, the vehicle direction, the destination, the search condition, and the like to the information center 51 via the network 63. When the information center 51 receives the vehicle position, the vehicle direction, the destination, the search condition, etc., route search processing means (not shown) of the CPU 54 performs route search processing similar to the CPU 31 and searches the database 58 for search data, etc. , And a route from the departure point to the destination is searched based on the vehicle position, vehicle direction, destination, search conditions, and the like, and route data representing the searched route is output. Next, a transmission processing unit (not shown) of the CPU 54 performs transmission processing and transmits the route data to the navigation device 14 via the network 63.

  Subsequently, a guidance processing means (not shown) of the CPU 31 performs guidance processing and provides route guidance. For this purpose, the route display processing means of the guidance processing means performs route display processing, reads the route data, and displays the searched route on the map screen according to the route data.

  By the way, in the route guidance, when the vehicle needs to turn right or left at a predetermined intersection on the searched route, the intersection is set as a guidance intersection, and route guidance for turning the vehicle right or left at the guidance intersection is performed. Is called. Further, in toll roads dedicated to automobiles such as expressways, city expressways, and toll roads, intersections that merge with junctions or branch off are also set as guidance intersections. Further, when the vehicle passes a predetermined facility on the searched route, for example, a level crossing, the level crossing is set as a guidance facility, and route guidance for temporarily stopping the vehicle at the guidance facility is performed.

  For this purpose, the guidance point setting processing means of the guidance processing means performs guidance point setting processing and sets guidance points such as guidance intersections and guidance facilities according to the route data.

  Then, the voice output point setting processing means of the guidance processing means performs voice output point setting processing, and at least one of the main points is located at a distance of the set distance before the guide point on the search route. In the embodiment, when a plurality of audio output points are set and the vehicle reaches each audio output point, the audio output processing unit of the guidance processing unit performs audio output processing, and for each audio output point A voice phrase is output with a guidance phrase having a preset content.

  For this purpose, the guidance phrase is set in advance for each distance from the voice output point to the guidance point, and is recorded in the data recording unit 16 as a guidance phrase map. The voice output processing means reads the position of the voice output point and the vehicle position, calculates the distance from the vehicle position to the voice output point, refers to the guidance phrase map, and guide phrases corresponding to each distance. Is read out and the sound is output.

  The guidance point enlarged map forming processing means of the guidance processing means performs a guidance point enlarged map forming process, and before the vehicle reaches the guidance intersection, an enlarged view of the guidance intersection in a predetermined area of the map screen, that is, An enlarged intersection map is formed as an enlarged guide map, and route guidance is performed using the enlarged map. Therefore, a guide point enlarged map display point is set at a position that is a set distance away from the guidance intersection on the searched route (on the vehicle position side), and the vehicle reaches the guide point enlarged map display point. Then, the intersection enlarged view is displayed.

  In this case, in the enlarged view of the intersection, a map around the guidance intersection, a search route, and a landmark such as a facility that is a landmark at the guidance intersection are displayed.

  Further, the guidance processing means can display additional information such as traffic jam information on the map screen. For this purpose, for example, the traffic jam indicator display processing means of the guidance processing means performs traffic jam indicator display processing, and shows traffic jam information in the traffic information, for example, whether it is up / down of the road where the traffic jam occurs, Is converted into a traffic jam zone as a traffic jam index that expresses the occurrence location of the traffic, the traffic jam length, etc., and the traffic jam zone is displayed along the road on the map screen. In this case, the color of the traffic jam zone or the like is changed to red, orange, etc. according to the traffic jam degree. In place of the traffic jam zone as the traffic jam index, a traffic jam arrow can be displayed, which indicates whether the road where the traffic jam has occurred, whether it is up or down, the location of the traffic jam, the length of the traffic jam, and the like.

  In this way, the driver can know the traffic jam situation on the roads around the vehicle, the searched route, and the like. The guidance processing means calculates the total travel time from the departure point to the destination based on the route data, statistical data, travel history data, traffic information, etc., or calculates the arrival time at the destination. can do.

  By the way, in the present embodiment, the driver parks the vehicle without noticing that it is a parking prohibition area as the first area, or notices that it is a parking prohibition area as the second area. In order to prevent the vehicle from being parked without parking, parking or parking is restricted when the vehicle position is within the parking / parking prohibition area or the parking prohibition area.

  That is, the vehicle restriction processing means (not shown) of the CPU 31 performs vehicle restriction processing, and if the vehicle position is in a parking / parking prohibition area or a parking prohibition area, it notifies the driver to that effect and parks the vehicle. Encourage them to move outside the parking prohibited area or outside the parking prohibited area.

  FIG. 2 is a flowchart showing the operation of the navigation device for restricting parking or parking of the vehicle in the embodiment of the present invention.

  First, the area determination information acquisition processing means of the vehicle restriction processing means performs area determination information acquisition processing, reads the own vehicle position, and captures the object to be imaged by the back camera 49, the front camera 61, and the side camera 62. Area determination information is acquired by reading image data.

  Subsequently, the area determination processing unit of the vehicle regulation processing unit performs an area determination process, performs image recognition based on the image data, specifies a captured object, and based on the specified object. To determine whether the vehicle position is within the parking and parking prohibited area. For this purpose, the image extraction processing means of the area determination processing means performs image extraction processing and extracts a predetermined image from the image data, and the image comparison processing means of the area determination processing means performs image comparison processing and data The image recognition data recorded in the recording unit 16 is referred to, and the extracted image and the image of the object to be photographed are compared. When the extracted image and the image of the object to be photographed match, the area determination processing means The subject identification processing means performs the subject identification processing and identifies the photographed subject.

  Subsequently, the area calculation processing means of the area determination processing means performs an area calculation process and calculates a parking / parking prohibition area based on the specified object to be photographed. For example, when the object to be photographed is a road sign indicating that it is a road where parking and parking are prohibited, the road where the road sign is installed is set as a parking prohibited area, and the object to be photographed is an intersection If the side of the intersection or a portion within a predetermined distance (5 [m]) from the corner of the road is a parking prohibition area, and the subject is a pedestrian crossing or bicycle crossing, If the part within a predetermined distance (5 [m]) from the front and back side ends of the belt is set as a parking stop prohibition area, and the object to be photographed is a level crossing, it is determined from the side ends before and after the crossing If the object within the distance (10 [m]) is a parking and parking prohibition area and the object to be photographed is a track or tunnel, the part of the track or tunnel is a parking and parking prohibition area. If is a safety zone On the road where the belt is provided, the left part of the safety zone and the part within a predetermined distance (10 [m]) from the front and rear side ends are set as parking prohibited areas, and the object to be photographed is a shared car If it is a sign pillar or sign board that displays the stop of trolley bus or tramway, the part within a predetermined distance (10 [m]) from the position where the sign pillar or sign board is provided is parked Made into a prohibited area.

  And when the own vehicle position is within the parking and parking prohibited area, the operation determination processing means of the parking and stopping regulation processing means performs the operation determination processing, and information when the driver operates the vehicle from the vehicle control device 10, That is, a range selection signal that is operation information is read to determine whether or not the driver has performed a predetermined operation, and in this embodiment, whether or not a parking range as a non-traveling range has been selected. The range selection signal is generated when the driver operates a shift lever as a range selection member to set a parking range, a reverse travel range, a neutral range, a drive range, a fourth speed range, a third speed range, a second speed range, or a first speed. When each range is selected, it is generated as a signal representing the selected range. The parking range and neutral range are ranges selected when the vehicle is not driven (non-traveling range), whereas the reverse traveling range, drive range, fourth speed range, third speed range, second speed The range or the first speed range is a range (running range) selected when the vehicle is driven.

  When the parking range is selected, the operation determination processing unit determines whether a predetermined time, in the present embodiment, 5 [minutes] has elapsed while the parking range is selected. In this case, if 5 [minutes] have elapsed with the parking range selected, the vehicle has stopped at that point for 5 [minutes].

  Accordingly, the regulation information notification processing means of the parking / stopping regulation processing means performs the regulation information notification processing, and when the driver determines that the vehicle is parked in the parking / parking prohibition area, the display unit 35 automatically The driver is notified by displaying that the vehicle position is within the parking and parking prohibited area, and warned to immediately move the vehicle. Further, in addition to the display on the display unit 35, the restriction information notification processing means notifies the vehicle output position 37 within the parking and parking prohibited area by the audio output unit 37, and immediately moves the vehicle. Audio output for warning can be performed.

  When the parking range is not selected, the restriction information notification processing means notifies the driver by displaying on the display unit 35 that the own vehicle position is within the parking and parking prohibited area. In this case, by displaying restriction information consisting of predetermined characters, symbols, marks, images, etc. in a predetermined position on the map screen, for example, in the vicinity of the periphery, it is possible that the vehicle position is within the parking and parking prohibited area. Is displayed. In addition, it is possible to display that the road is within the parking and parking prohibited area along the road where the vehicle position is placed.

  On the other hand, when the own vehicle position is not within the parking / forbidden parking area, the area determination processing unit determines whether the own vehicle position is within the parking prohibited area based on the identified object to be photographed.

  Therefore, the area calculation processing unit calculates a parking prohibited area based on the specified object to be photographed. For example, if the object to be photographed is a road sign indicating that parking is prohibited, the road where the road sign is installed is set as a parking prohibited area, and the object to be photographed is used for getting in and out of people. When it is an entrance / exit for a car that touches a road at a facility or place located outside the road for cargo loading / unloading, parking, or car storage / repair, within a predetermined distance (3 [m]) from the entrance / exit If the part is a parking prohibition area and the object to be photographed is a construction area where road construction is performed, the part within a predetermined distance (5 [m]) from the side edge of the construction area is designated as a parking prohibition area. When the object to be photographed is a place for fire fighting machinery or equipment, a fire prevention water tank for fire fighting, or an entrance in contact with these roads, a predetermined distance (5 [M]) Is a parking prohibited area and the object to be photographed is a fire hydrant, a designated firefighting water use sign, or a water inlet or suction pipe inlet of a firefighting fire prevention water tank, the fire hydrant, designated firefighting water use sign, or fire prevention fire prevention When a portion within a predetermined distance (5 [m]) from the water inlet of the water tank or the suction pipe insertion hole is set as a parking prohibited area and the object to be photographed is a fire alarm, the predetermined distance (1 [1] from the fire alarm m]) is the parking prohibited area. When the object to be photographed is an edge of a road on the right side of the vehicle, a place where there is no room on the road for a predetermined distance (3.5 [m]) or more is set as a parking prohibited area.

  When the vehicle position is within the parking prohibited area, the operation determination processing unit reads an engine drive signal that is operation information from the vehicle control device 10 and determines whether the engine has been stopped.

  When the engine is stopped, the regulation information notification processing means determines that the driver is about to park the vehicle in the parking prohibited area, and the display unit 35 shows that the vehicle position is in the parking prohibited area. The driver is notified by displaying a certain fact and warned to move the vehicle immediately. Further, the restriction information notification processing means notifies the fact that the vehicle position is within the parking prohibited area by the voice output unit 37, and performs voice output to warn to move the vehicle immediately, or to display the display. In addition to the display on the unit 35, voice output can be performed.

  And when the said parking range is not selected, a regulation information notification process means notifies a driver | operator by displaying on the display part 35 that the own vehicle position exists in a parking prohibition area. In this case, the vehicle information is displayed on the display unit 35 by displaying restriction information including predetermined characters, symbols, marks, images, etc. different from the restriction information at a predetermined position on the map screen, for example, in the vicinity of the periphery. Notify the driver that the location is within the parking prohibited area. In addition, it is possible to display that the road is within the parking prohibited area along the road where the vehicle position is placed.

  As described above, in the present embodiment, image recognition is performed based on the image data of the object captured by the back camera 49, the front camera 61, and the side camera 62, the captured object is identified, Based on the identified object, it is determined whether the vehicle position is in the parking prohibition area and whether the vehicle position is in the parking prohibition area. Data on areas and parking prohibited areas is no longer required.

  Therefore, since it is not necessary to record data on the parking / prohibited parking area and the parking prohibited area in the data recording unit 16, the amount of data can be reduced, and the capacity of the data recording unit 16 can be reduced. . As a result, the cost of the information notification system can be reduced.

  In addition, for example, when a new entrance / exit for a car is formed in a predetermined facility or a road construction is newly performed, a predetermined location becomes a new parking prohibition area. Therefore, it is possible to determine whether or not the vehicle position is within the parking prohibited area, so that the vehicle is not parked without noticing that it is the parking prohibited area.

  Even if the vehicle position is within the parking prohibition area or the parking prohibition area, if the parking range is not selected or the engine is not stopped, no warning is given. Thus, it is possible to prevent unnecessary warnings from being made when the vehicle is stopped.

Next, a flowchart will be described.
Step S1: It is determined whether or not the own vehicle position is within a parking and parking prohibited area. If it is within the parking and parking prohibited area, the process proceeds to step S2, and if it is not within the parking and parking prohibited area, the process proceeds to step S5.
Step S2: It is determined whether a parking range has been selected. When the parking range is selected, the process proceeds to step S3, and when not selected, the process proceeds to step S4.
Step S3: It is determined whether 5 minutes have elapsed. If 5 minutes have passed, the process proceeds to step S8, and if not, the process returns to step 2.
Step S4 It is displayed that the own vehicle position is within the parking and parking prohibited area.
Step S5: It is determined whether or not the vehicle position is within the parking prohibited area. If it is within the parking prohibited area, the process proceeds to step S7. If it is not within the parking prohibited area, the process is terminated.
Step S6: Determine whether the engine has been stopped. When the engine is stopped, the process proceeds to step S8, and when the engine is not stopped, the process proceeds to step S7.
Step S7 It is displayed that the vehicle position is within the parking prohibited area.
Step S8 A warning is displayed and the process is terminated.

  In the present embodiment, it is always determined whether or not the vehicle position is within the parking / restricted parking area or the parking prohibited area, but based on the traffic jam information, the vehicle is stopped in response to the traffic jam. When it is determined whether or not the vehicle has been stopped due to traffic jam, it is possible to prevent the parking and stopping regulation process from being performed.

  In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

It is a figure which shows the navigation system in embodiment of this invention. It is a flowchart which shows operation | movement of the navigation apparatus for regulating parking / stopping of a vehicle or parking in embodiment of this invention.
