(First embodiment)
The first embodiment of the present invention will be described below. FIG. 1 shows a hardware configuration of a vehicle navigation apparatus 1 according to this embodiment. In the present embodiment, the vehicle navigation device 1 warns according to the distance to the warning point when the host vehicle comes before a warning point (corresponding to a warning point) such as a curve or a railroad crossing. Change the strength of the displayed content.

  In order to realize such a function, the vehicle-mounted navigation device 1 includes a position detector 11, an operation switch group 12, an image display device 13, a speaker 14, a RAM 16, a ROM 17, an external storage medium 18, and a CPU 19. . The CPU 19 is connected to the head-up display 2.

  The head-up display 2 is a semi-permeable membrane surface embedded in the entire or part of the windshield surface of the vehicle, and a video light based on an image signal output from the vehicle navigation device 1 in the dashboard of the vehicle. Is projected onto the semipermeable membrane surface. With such a configuration, the head-up display 2 can display an image based on the image signal from the vehicle navigation device 1 on the windshield. Note that the area where the image is displayed on the windshield may be a portion overlapping the road ahead when viewed from the driver, or the entire windshield.

  The position detector 11 includes a well-known sensor (not shown) such as a geomagnetic sensor, a gyroscope, a vehicle speed sensor, and a GPS receiver. The current position and direction of the vehicle based on the characteristics of each of these sensors. Is output to the CPU 19.

  The operation switch group 12 includes a plurality of mechanical switches provided in the vehicle navigation device 1 and an input device such as a touch panel provided so as to overlap the display surface of the image display device 13. A signal based on the touch is output to the CPU 19.

  The image display device 13 is provided on the dashboard of the vehicle, in the dashboard, and the like, and displays a video based on the video signal output from the CPU 19 to the user. Examples of the display image include a map centering on the current location.

  The external storage medium 18 is a non-volatile storage medium such as an HDD (hard disk drive), and stores a program read and executed by the CPU 19, map data for route guidance, a warning level table, and the like.

  The map data includes road piece (link) and intersection (node) position information, road data such as connection relation information between the intersection and the road piece, shape data such as the curvature radius of the road piece, and facility data. . The road data also includes road type information such as road width for each road piece, highway, and general road. The facility data has a plurality of entries for each facility, and each entry has data indicating name information, location information, facility type information, and the like of the target facility.

  FIG. 2 shows an example of a warning level table. The warning level table has a plurality of entries for each distance range to a warning point such as a curve or a railroad crossing, and each entry has a distance range corresponding to the entry, a warning level (corresponding to a warning level), and a warning. Has content data.

  In the present embodiment, the warning level table has three entries, and each entry corresponds to a distance range of A meter or more, less than A meter, B meter or more, and less than B meter to the warning point. However, A> B, for example, A = 100 and B = 10.

  The warning level is from level 1 to level 3. The warning level of the entry of A meters or more up to the warning point (hereinafter referred to as the first warning entry) is the lowest level 1, and the entry of B meters less than A meter up to the warning point (hereinafter referred to as the second warning entry). The warning level is level 2, and the warning level of the entry less than B meters up to the warning point (hereinafter referred to as the third warning entry) is the maximum level 3. That is, the warning level is higher as the entry is closer to the guidance point.

  The warning contents include warning display mark shape data (for example, an arrow mark indicating a curve direction), mark display size data, mark blinking interval data, mark display color saturation or luminance data, mark head-up display 2 The upper display position data, the display transmittance data of the mark head-up display 2, and the like. In the warning level table of the present embodiment, the higher the warning level, the higher the warning display intensity. Specifically, the higher the guidance level, the larger the display size of the mark, the shorter the blinking interval of the mark, the higher the saturation or luminance of the display color, and the lower the transmittance (which makes it difficult to transmit). Each entry in the warning level table includes mark display size data, mark blinking interval data, mark display color saturation data, luminance data, mark display position data on the head-up display 2, and mark head-up. Any one of the display transmittance data in the display 2 may be included, or any of them may be included.

  A CPU (corresponding to a computer) 19 executes a program for the operation of the vehicle navigation apparatus 1 read from the ROM 17 and the external storage medium 18, and from the RAM 16, the ROM 17, and the external storage medium 18 at the time of execution. Information is read, information is written to the RAM 16 and the external storage medium 18, and signals are exchanged with the head-up display 2, the position detector 11, the operation switch group 12, the image display device 13, and the speaker 14.

  Specific processing performed by the CPU 19 executing the program includes current position specifying processing, guidance route search processing, route guidance processing, and warning display control processing.

  The current position specifying process is a process of repeatedly specifying the current position, direction, speed, etc. of the vehicle based on a signal from the position detector 11 using a known technique such as map matching.

  The guide route search process is a process of receiving an input of a destination by the user from the input device and calculating an optimum guide route from the current position to the destination.

  In the route guidance processing, map data is read from the external storage medium 18, and an image in which the calculated guidance route, destination facility, transit facility, current position, etc. are superimposed on the map is displayed on the image display device 13 or the head-up display 2. This is a process for outputting to the speaker 14 a guidance voice signal for instructing a right turn, a left turn, etc., when necessary, for example, when the host vehicle arrives before the guidance intersection.

  The warning display control process calculates the distance to the warning point of the host vehicle, and causes the head-up display 2 to perform the shorter the calculated distance based on the speed of the host vehicle being equal to or higher than a predetermined allowable speed. This is a process for increasing the intensity of a warning display (corresponding to a warning display). However, in the warning display control process, the intensity of the warning display to be performed by the head-up display 2 based on the detection of the driver's corresponding operation based on the recognition of the warning point, such as the deceleration operation of the vehicle, It is lower than the case where it is not detected.

  3 and 4 show a flowchart of the warning display control program 100 executed by the CPU 19 in order to realize such a warning display control process. When the host vehicle approaches the warning point, the CPU 19 repeats the execution of the warning display control program 100 until the vehicle passes the warning point. Whether or not a certain place is a warning point depends on whether or not the place is a curve having a curvature higher than the reference based on the map data of the external storage medium 18 and whether or not the place is a railroad crossing. judge. Whether or not the host vehicle has reached before the warning point is based on the current position and direction of the host vehicle specified by the current position specifying process, and has approached the direction within a predetermined distance (for example, 300 meters). Judge by no.

  In the execution of the warning display control program 100, the CPU 19 first calculates a linear distance to the warning point of the own vehicle or a distance along the road based on the map data and the result of the current position specifying process in step 110, Further, the current traveling speed is calculated.

  Subsequently, in step 115, it is determined whether or not the traveling speed calculated in step 110 is equal to or higher than a predetermined allowable speed (for example, 40 kilometers per hour). Execution is terminated, and if it is equal to or greater than the allowable speed, then step 120 is executed. The allowable speed may vary depending on the type of warning point (whether it is a curve or a railroad crossing), or may increase as the curvature radius of the curve increases.

  In step 120, an entry corresponding to the distance to the warning point of the host vehicle specified in step 110 is read from the warning level table, and the warning level in the entry is specified as the current warning level.

  In step 130, a warning is displayed. The specific contents of this warning display are as shown in the flowchart of FIG. That is, in the execution of step 130, first, in step 132, whether or not there is a deceleration operation of the own vehicle, the speed of the own vehicle specified in step 110 in the execution of the current warning display control program 100, and past warnings are performed. The determination is made based on the comparison with the speed of the host vehicle specified in step 110 in the execution of the display control program 100. In addition, whether or not there is a deceleration operation may be determined based on, for example, whether or not the brake pedal has been depressed based on a signal from a brake pedal sensor that detects the depression of the brake pedal by the driver. . If there is a deceleration operation, then step 134 is executed, and if there is no deceleration operation, then step 136 is executed.

  In step 136, warning control according to the warning level is performed in the normal mode. The normal mode is a mode in which the warning content as described in the warning level table is displayed on the head-up display 2. Specifically, an entry corresponding to the warning level specified in step 120 in the warning level table is read, and a warning display mark is displayed on the head-up display 2 according to the warning content in the entry. After step 136, one execution of the warning display control program 100 ends.

  In step 134, warning control corresponding to the warning level is performed in the reduction mode. The experience mode is a mode in which warning content having a lower intensity than the warning content described in the warning level table is displayed on the head-up display 2. Specifically, the entry corresponding to the warning level specified in step 120 in the warning level table is read, and the warning display mark is displayed on the head-up display 2 with a lower intensity than the warning content in the entry. Examples of lowering the intensity include hiding the warning display mark, reducing the display size of the warning display mark, increasing the warning display mark blinking interval, disabling the warning display mark, and warning. For example, the saturation of the color of the display mark is lowered, the luminance of the color of the warning display mark is lowered, and the transmittance of the color of the warning display mark is raised. In step 134, one of these exemplified methods for reducing the intensity may be performed, or any of them may be executed. After step 134, one execution of the warning display control program 100 ends.

  When the CPU 19 executes such a warning display control process, the vehicle navigation apparatus 1 can increase the intensity of the warning display as the distance from the host vehicle to the warning point becomes shorter. Further, the intensity of the warning display can be reduced based on detecting the corresponding operation of the driver based on the recognition of the warning point after reaching the warning point. Therefore, the possibility that the driver is bothered by displaying an unnecessary warning is reduced, and the possibility that the warning is reliably transmitted to the driver is increased.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. FIG. 5 shows a hardware configuration of the vehicle navigation apparatus 1 ′ according to the present embodiment. In the present embodiment, the vehicle navigation device 1 ′ is provided in front of a guide point (corresponding to a warning point) such as an intersection where the host vehicle does not travel along a road, a branch on a highway, and an exit on a highway. When applied, the strength of the guidance display content is changed according to the distance to the guidance point. Hereinafter, only the parts of the present embodiment different from the first embodiment will be described in detail.

  The hardware configuration of the vehicular navigation device 1 ′ of the present embodiment is different from the vehicular navigation device 1 of the first embodiment in that the vehicular navigation device 1 ′ has a blinker sensor 15.

  The turn signal sensor 15 detects blinking of the turn signal of the vehicle and outputs a detection signal to the CPU 19. Detection of blinking of the winker can be realized by detecting whether or not power is supplied to the winker, for example. The CPU 19 can detect whether or not the blinker sensor 15 is blinking based on a signal from the blinker sensor 15.

  The external storage medium 18 has a guidance level table instead of the warning level table. FIG. 6 shows an example of the guidance level table. The guidance level table is divided into a plurality of road-specific tables for each road type such as a highway and a general road. Each of the road tables has a plurality of entries for each distance range to the guidance point, and each entry has a distance range corresponding to the entry, a guidance level (corresponding to a warning level), and guidance contents. Have the data.

  In the present embodiment, each road table has three entries, and each entry corresponds to a distance range of A meter or more, less than A meter, B meter or more, and less than B meter to the guide point. However, A> B. Further, the values of A and B may be changed for each road type, that is, for each road table. For example, A = 500 and B = 100 in the road table for the expressway, and A = 100 and B = 10 in the road table for the general road (in FIG. 6, the road table for the general road). Here, A is written as α and B is written as β).

  The guidance level is from level 1 to level 3. The guidance level for entries above A meter up to the guidance point is the lowest level 1, the guidance level for entries below B meters up to the guidance point is Level 2, and below B meters up to the guidance point The guidance level of the entry is the maximum level 3. That is, the guidance level is higher as the entry is closer to the guidance point.

  The contents of the guidance include the shape data of the display mark for guidance (for example, the arrow mark indicating the direction of turning left and right), the display size data of the mark, the blinking interval data of the mark, the saturation or luminance data of the mark display color, 2 display position data, display transmittance data of the mark head-up display 2, and the like. In the road-specific table of the present embodiment, the strength of the guidance display increases as the guidance level increases. Specifically, the higher the guidance level, the larger the mark display size, the shorter the blinking interval of the mark, the higher the saturation or luminance of the display color, and the lower the effectiveness rate (hard to transmit). Each entry in the road table includes mark display size data, mark blink interval data, mark display color saturation data, luminance data, mark head-up display 2 display position data, and mark head-up. Any one of the display transmittance data in the display 2 may be included, or any of them may be included.

  Further, the CPU 19 of the vehicle navigation device 1 ′ executes a guidance display control process instead of the warning display control process in the first embodiment.

  The guidance display control process is a process of calculating the distance to the guidance point of the host vehicle and increasing the strength of the guidance display (corresponding to the alert display) to be performed by the head-up display 2 as the calculated distance becomes shorter. . However, in the guidance display control process, the intensity of the guidance display to be performed by the head-up display 2 based on the detection of the driver's corresponding operation based on the recognition of the guidance point, such as a vehicle deceleration operation or a blinker operation, The corresponding operation is set lower than when no operation is detected.

  7 and 8 show a flowchart of a guide display control program 200 executed by the CPU 19 in order to realize such a guide display control process. When the host vehicle approaches the guidance point while the route guidance process is being executed, the CPU 19 repeats the execution of the guidance display control program 200 until the vehicle passes the guidance point. Whether or not a place is a guidance point is whether or not the place is a right / left turn intersection, expressway branch point, expressway exit, etc. along the guidance route calculated by the guidance route search process. Judge by.

  In the execution of the guidance display control program 200, the CPU 19 first calculates a linear distance to the guidance point of the own vehicle or a distance along the road based on the map data and the result of the current position specifying process in step 210, Further, the road type of the road that is currently running is specified.

  Subsequently, in step 220, an entry corresponding to the distance to the guidance point is read from the road type table corresponding to the traveling road type of the host vehicle specified in step 210, and the guidance level in the entry is set to the current level. Specify as the guidance level.

  In step 230, guidance display is performed. The specific contents of this guidance display are as shown in the flowchart of FIG. That is, in the execution of step 230, first, in step 232, it is determined whether or not there is a deceleration operation or a blinker operation of the host vehicle. Whether or not there is a deceleration operation is determined based on the current travel speed based on the result of the current position specifying process, the travel speed, and the travel speed identified in this step in the execution of the past guidance display control program 200. Judgment based on the comparison. Moreover, you may determine whether there exists deceleration operation based on the signal from a brake pedal sensor like 1st Embodiment. Whether or not there is a winker operation is determined based on a signal from the winker sensor 15. If there is a deceleration operation or a turn signal operation, then step 234 is executed, and if there is no deceleration operation or a turn signal operation, then step 236 is executed.

  In step 236, guidance control according to the guidance level is performed in the normal mode. The normal mode is a mode in which the guidance content as described in the guidance level table is displayed on the head-up display 2. Specifically, an entry corresponding to the guidance level specified in step 120 in the corresponding road type table is read, and a guidance display mark is displayed on the head-up display 2 according to the guidance content in the entry. After step 236, one execution of the guidance display control program 200 ends.

  In step 234, guidance control according to the guidance level is performed in the reduction mode. The experience mode refers to a mode in which guidance content having lower strength than guidance content described in the guidance level table is displayed on the head-up display 2. Specifically, the entry corresponding to the guidance level specified in step 220 in the corresponding road type table is read, and the head-up display 2 displays a guidance display mark that is lower in intensity than the guidance content in the entry. Examples of reducing the intensity include hiding the guide display mark, reducing the display size of the guide display mark, increasing the guide display mark blinking interval, preventing the guide display mark from blinking, and guidance. For example, the saturation of the color of the display mark is lowered, the luminance of the color of the guide display mark is lowered, and the transmittance of the color of the guide display mark is increased. In step 234, one of these exemplified methods for reducing the intensity may be performed, or any of them may be executed. After step 234, execution of the guidance display control program 200 for one time is completed.

  When the CPU 19 executes such guidance display control processing, the vehicle navigation apparatus 1 can increase the strength of guidance display as the distance from the host vehicle to the guidance point becomes shorter. Further, the strength of the guidance display can be reduced based on detecting the corresponding operation of the driver based on the recognition of the guidance point after approaching the guidance point. Therefore, the possibility that the driver is bothered by displaying unnecessary guidance is reduced. In addition, there is a high possibility that guidance will be transmitted to the driver.

  Here, the correspondence between the constituent elements of the above-described embodiments and the constituent elements of the claims will be described. The vehicle navigation devices 1, 1 ′ in the above embodiments correspond to a warning display control device. The head-up display 2 corresponds to a display device.

  Further, the warning display control program 100 and the guidance display control program 200 correspond to the alerting control program.

  The CPU 19 functions as a display control unit by executing steps 134 and 136 of the alert display control program 100 and steps 234 and 236 of the alert display control program 200.

  Further, the CPU 19 executes step 110 of the alert display control program 100 and step 210 of the alert display control program 200, thereby functioning as calculation means.

  Further, the CPU 19 functions as a detection unit by executing step 132 of the alert display control program 100 and step 232 of the alert display control program 200.

(Other embodiments)
In each of the above-described embodiments, the vehicle navigation device 1 causes the head-up display 2 to perform warning display and guidance display (that is, warning display). This warning display is performed on the image display device 13. Or may be performed by the speaker 14. In this case, the image display device 13 and the speaker 14 correspond to the display device. In the case where the speaker 14 performs a warning display by voice, it is only necessary that the volume of the voice increases as the distance of the host vehicle to the warning point and the guidance point (that is, the warning point) decreases. In addition, when the driver's response operation based on the recognition of the alert point is detected, the distance from the vehicle to the alert point is the same, and the driver's response operation based on the alert point recognition is not detected. Then, the volume of the sound can be reduced.

  In the above embodiment, each of the warning level table and the guidance level table has three stages as the distance to the alerting point. However, the number of stages may be four or more.

  In each of the above embodiments, the closer the vehicle is to the alert point, the stronger the alert display, and the recognition of the alert point when the driver's corresponding operation based on the alert point is detected. Although the intensity of the warning display is lower than that in the case where the corresponding operation of the driver based on is not detected, these may not necessarily be compatible.

  For example, there is no change in the intensity of the alert display between when the driver's corresponding operation based on recognition of the alert point is detected and when the driver's corresponding operation based on recognition of the alert point is not detected. The intensity of the alert display may increase as it is closer to the alert point.

  Also, for example, if the intensity of the alert display does not change regardless of the distance from the vehicle to the alert point, and if a driver's corresponding operation based on the alert point is detected, the alert point is recognized. The intensity of the alert display may be lower than when no corresponding operation of the driver is detected.
