The route information acquisition unit 71, the position information acquisition unit 72, the own vehicle information acquisition unit 73, and the outside world information acquisition unit 74 are functional units that acquire information from the communication bus 99.

When the destination is set in the navigation device 50, the route information acquisition unit 71 acquires the route information related to the route guidance to the destination and the navigation map data used for the route guidance from the navigation ECU 52. In addition, the route information acquisition unit 71 acquires the guidance implementation request output by the navigation ECU 52 together with the route information, the navigation map data, and the like based on the approach to the guidance point.

The route information acquisition unit 71 can perform a process of acquiring high-precision map data from the locator 40 together with the navigation map data or in place of the navigation map data. The route information acquisition unit 71 requests the locator ECU 44 to provide related high-precision map data based on the route information acquired from the navigation ECU 52. When the high-precision map data requested in this way is stored in the high-precision map DB 43, the route information acquisition unit 71 acquires the high-precision map data returned from the locator ECU 44.

It is information which shows continuation with P2 "). When the route information transmitted together with the guidance execution request includes the information of a plurality of guidance points, the continuous guidance determination unit 75 is continuous with these guidance points, that is, the route information includes the continuous information. It is determined that it is.

Here, the right / left turn point P1 is limited to a guide point where a branch such as a right turn or a left turn occurs, such as an intersection. On the other hand, the continuous point P2 may be any one of a branch point such as an intersection, a destination of a set route, and an alarm point for calling attention such as a temporary stop and a slow speed.

In addition, three or more guide points may be continuous on the set path at intervals less than a predetermined distance (hereinafter, “threshold distance”) from each other. In this case, the intermediate continuous point P2 sandwiched between the first right / left turn point P1 and the last continuous point P2 is limited to a branch point such as an intersection, like the right / left turn point P1. For example, when a plurality of (4 times) branches occur continuously, the group of route information includes information on a plurality of (4) guide points. In the continuous guidance determination unit 75, the first guidance point is the right / left turn point P1, and the second to fourth guidance points are the continuous points P2 for convenience.

The roadside object determination unit 76 determines whether or not there is a specific object in the roadside area of the road on which the vehicle A travels, based on the detection information acquired by the outside world information acquisition unit 74. The specific object is an object for which conditions are set in advance, as it is not appropriate as a target for superimposing a virtual image Vi (hereinafter, “guidance content CNT2”, see FIG. 6) that guides the continuous point P2. Specifically, the roadside object determination unit 76 identifies the shield BO (see FIG. 6) provided in the roadside area as described above as a specific object.

The vehicle posture determination unit 77 acquires the content of the guidance content CNT2 (see FIG. 6) used for guiding the continuous point P2 from the display generation unit 78 as content information. The vehicle posture determination unit 77 estimates the direction of the vehicle A turning at the right / left turn point P1 with respect to the connecting road Rc. The vehicle posture determination unit 77 grasps the guidance content CNT2 used for guiding the continuous point P2 based on the content information, and determines whether or not the orientation of the vehicle A is such that the grasped guidance content CNT2 can be displayed. (Hereinafter, "driving direction determination"). When the vehicle posture determination unit 77 determines that the vehicle A is facing in a direction in which the guidance content CNT2 can be displayed by the execution of the traveling direction determination, the vehicle direction determination is established and the display permission of the guidance content CNT2 is displayed. Notify 78.

The vehicle posture determination unit 77 can determine the traveling direction by using a plurality of acquired information different from each other. The first traveling direction determination is performed based on the detection information of the front camera 31 acquired by the outside world information acquisition unit 74. This detection information may be the image pickup data of the front camera 31, or may be the analysis result of the image pickup data as described above. The vehicle posture determination unit 77 grasps the relative position of the lane marking or the road end on the connecting road Rc based on the detection information. The vehicle posture determination unit 77 establishes a straight-ahead determination at the timing when the lane markings or road edges located on the left and right sides of the vehicle A enter the angle of view of the front camera 31 and can be photographed. .. The vehicle posture determination unit 77 may establish the straight-ahead determination at the timing when the lane marking on one side or the road end enters the angle of view of the front camera 31.

The second traveling direction determination is performed using the navigation map data or high-precision map data acquired by the route information acquisition unit 71 and the direction information acquired by the position information acquisition unit 72. For example, when neither the lane marking line of the connecting road Rc nor the road edge can be detected from the imaging data, the traveling direction determination is performed by combining the map data and the direction information.

Based on the map data, the vehicle posture determination unit 77 calculates the intersection angle θ1 at the right / left turn point P1 between the road toward the right / left turn point P1 (hereinafter, “first road R1”) and the connecting road Rc. The vehicle posture determination unit 77 sets a threshold angle θth (θ1> θth) slightly smaller than the crossing angle θ1 with reference to the crossing angle θ1. The vehicle attitude determination unit 77 calculates the attitude change angle θc of the vehicle A in the yaw direction at the right / left turn point P1 based on the direction information, with reference to the extension direction of the first road R1. The vehicle attitude determination unit 77 establishes the straight-ahead determination at the timing when the attitude change angle θc exceeds the threshold angle θth.

The third traveling direction determination is performed using the steering angle information acquired by the own vehicle information acquisition unit 73. For example, when it is difficult to detect the lane marking and the road end of the connecting road Rc and the reception environment of the positioning signal is not good, the traveling direction determination using the steering angle information is performed.

The vehicle attitude determination unit 77 monitors the transition of the steering operation at the right / left turn point P1 based on the steering angle information. The vehicle attitude determination unit 77 establishes the straight-ahead determination when the angular velocity of the steering becomes less than a predetermined speed, that is, when the change in the steering angle has settled down. The vehicle attitude determination unit 77 may establish the straight-ahead determination at the timing when the steering angle becomes less than a predetermined threshold value in the process of returning the steering based on the steering angle information. In this case, the predetermined threshold value for establishing the straight-ahead determination is appropriately changed based on the map data according to the intersection angle θ1 and the shape of the connecting road Rc.

The vehicle posture determination unit 77 changes the determination criteria for establishing the straight-ahead determination in the traveling direction determination according to the type of the guidance content CNT2. When the vehicle attitude determination unit 77 has the continuous point P2 as the destination and the guidance content CNT2 is superimposed on the building or the like in the roadside area which is the goal point, the vehicle attitude determination unit 77 relaxes the determination criteria for establishing the straight-ahead determination, and the guidance content CNT2 Advance the timing to start the display of.

In addition, the vehicle posture determination unit 77 changes the determination criteria for establishing the straight-ahead determination according to the line-of-sight condition of the roadside area of the connecting road Rc. When the vehicle attitude determination unit 77 determines that the roadside object determination unit 76 does not have a shield BO (see FIG. 6) in the roadside area of the connecting road Rc, the vehicle attitude determination unit 77 determines that there is a shield BO in the roadside area. However, the judgment criteria for establishing a straight-ahead judgment are relaxed. Also in this case, adjustments are made to accelerate the display start of the guidance content CNT2.

The display generation unit 78 generates video data to be sequentially output to the HUD device 20. When the route information acquisition unit 71 acquires the guidance execution request output by the navigation ECU 52, the display generation unit 78 superimposes and displays the original image of the content displayed on the foreground at the guidance point on each frame image constituting the video data. draw. The display generation unit 78 has a function of selecting the content to be used at the guide point, a function of drawing the content, a function of controlling the display period of the content, and the like.

The display generation unit 78 selects the content to be used for route guidance at each guidance point based on the route information and map data acquired by the route information acquisition unit 71. The display generation unit 78 prepares the drawing data of the selected content so that it can be drawn by image processing such as combining the parts data stored in the storage unit 13.

The display generation unit 78 uses either the guidance execution request notified by the navigation ECU 52 or the display permission notified by the vehicle posture determination unit 77 as a trigger, and sets the timing of the display start and the display end of the display content. Control. Based on the acquisition of these guidance implementation requests or display permission notifications, the display generation unit 78 converts the prepared drawing data into each frame image in front of each guidance point in a form that matches the traveling of the vehicle A along the set route. Start the drawing process.

When the continuous guidance determination unit 75 determines the continuity of the right / left turn point P1 and the continuous point P2, the display generation unit 78 displays the right / left turn content CNT1 (see FIG. 5) and the guidance content CNT2 (see FIG. 6). Draw in order on the frame image. The details of the guidance display in such a continuous branch will be described with reference to FIGS. 1 and 3 based on FIGS. 4 to 6.

When the navigation device 50 has set a route for continuously turning right and left, the navigation ECU 52 provides guidance at a predetermined distance (for example, 300 m) before the first intersection (right / left turn point P1). The route information is output to the HCU 100 together with the request. This route information includes distance information to the first intersection, distance information between the two intersections (for example, 150 m), the direction of turning left and right at each intersection, navigation map data showing the shape of the intersection, and the number of lanes. It also contains lane information and the like that indicate the direction of travel allowed for each lane.

The display generation unit 78 starts drawing the right / left turn content CNT1 that guides the right / left turn point P1 on each frame image based on the acquisition of the guidance implementation request by the route information acquisition unit 71. As shown in FIG. 5, the right / left turn content CNT1 is superimposed and displayed on the road surface of the first road R1, and shows the driver the planned travel locus of the vehicle A based on the route information. In the route guidance scene shown in FIG. 4, the right / left turn content CNT1 AR displays the approach route to the right / left turn point P1 and the exit route from the right / left turn point P1. With such a display, the right / left turn content CNT1 urges the driver to move to the right turn lane until the right / left turn point P1 is reached and to make a right turn at the right / left turn point P1.

When the right turn of the vehicle A is started at the right / left turn point P1, the vehicle posture determination unit 77 determines the traveling direction. When the vehicle attitude determination unit 77 establishes a straight-ahead determination based on the image pickup data or the like, the vehicle attitude determination unit 77 notifies the display generation unit 78 of the display permission of the guidance content CNT2. The display generation unit 78 starts drawing the guidance content CNT2 that guides the continuous point P2 on each frame image based on the acquisition of the display permission notification.

As shown in FIG. 6, the guidance content CNT2 is superimposed and displayed on the road surface of the connecting road Rc, and shows the driver the planned travel locus of the vehicle A based on the route information. In the route guidance scene shown in FIG. 4, the guidance content CNT2 AR displays the approach route to the continuous point P2 and the exit route from the continuous point P2. With such a display, the guidance content CNT2 indicates the relative position of the continuous point P2 and prompts the driver to make a left turn at the continuous point P2.

The details of the guidance display processing performed by the HCU 100 will be described below with reference to FIGS. 3 and 4 based on the flowchart shown in FIG. 7. The guidance display process shown in FIG. 7 is started based on the guidance implementation request notified from the navigation ECU 52 to the HCU 100.

In S101, the navigation-related information related to the guidance execution request that triggered the start of the guidance display processing this time, specifically, the position information, the direction information, the route information, and the like of the vehicle A are acquired, and the process proceeds to S102.

In S102, the route information acquired in S101 is referred to, and it is determined whether or not continuous guidance is performed based on whether or not the route information includes continuous information. If it is determined in S102 that continuous guidance is not performed, the process proceeds to S104. On the other hand, if it is determined in S102 that continuous guidance is to be performed, the process proceeds to S103. In S103, the number of continuous guide points is set based on the route information, the route information in the series of guide sections is separated as the information of each guide point, and the process proceeds to S104.

In S104, the numerical value of the counter for counting the guide points is set to "1", and the process proceeds to S105. In S105, the content about the current (Nth) guide point is generated based on the numerical value of the counter. Specifically, by drawing the content on the video data, the AR display of the content is started, and the process proceeds to S106.

In S106, it is determined whether or not there is a next (N + 1th) guide point. If there is no next guide point, the display end timing of the current (Nth) display content is determined. In this case, for example, the timing of traveling a predetermined distance after passing the current guide point is set as the display end timing. If it is determined in S106 that the display end timing has come, the process proceeds to S107.

On the other hand, in S106 when there is a next (N + 1st) guide point (continuous point P2), the traveling direction determination is performed. If it is determined in S106 that the timing is such that the next guidance content CNT2 can be displayed based on the establishment of the straight-ahead determination of the vehicle A, the process proceeds to S107. In S107, the AR display of the current (Nth) guidance content CNT2 is finished, and the process proceeds to S108.

In S108, it is determined whether or not there is a remaining guide point set in S103. If it is determined in S108 that there are no remaining guidance points, a series of guidance display processes based on the current guidance implementation request is terminated. On the other hand, if it is determined in S108 that there are remaining guide points, the process proceeds to S109.

In S109, the value of the counter of the guide point is increased by one, and the process proceeds to S105. In the second and subsequent S105s, the generation of the guidance content CNT2 that guides the next (N + 1st) guide point, that is, the continuous point P2, and the AR display are started based on the value of the counter incremented in S109. Then, in the subsequent S106 to S109, the AR display switching or termination is awaited. When the guidance at all the guidance points is completed in this way, the series of guidance display processing based on the current guidance implementation request is completed.

In the present embodiment described so far, when the right / left turn point P1 and the continuous point P2 are continuous, the display of the guidance content CNT2 that guides the continuous point P2 is displayed after the start of the right turn or the left turn at the right / left turn point P1. It starts on the condition that the straight-ahead judgment is established. Based on the above, the display start timing of the guidance content CNT2 that guides the continuous point P2 may be appropriate. Therefore, the risk of erroneous recognition due to the superimposed display for route guidance can be reduced.

More specifically, as in the comparative example shown in FIG. 8, when the display of the content CNTX that guides the next guide point (continuous point) is started while turning at the right / left turn point, at least a part of this content CNTX. Can be superimposed and displayed on the shield BO in the roadside area. For example, when switching to the content CNTX is performed based on the result of the map matching process performed by the navigation ECU 52, the display switching as in this comparative example is likely to occur. Then, the content CNTX that is started to be displayed when the vehicle A is not facing the front of the road may be a display that may give a misunderstanding or annoyance to the driver. Therefore, it becomes difficult for the information presented by the content CNTX to be correctly transmitted to the driver.

On the other hand, in the present embodiment shown in FIG. 6, the display start timing of the guidance content CNT2 is started according to the establishment of the straight-ahead determination of the vehicle A. Therefore, the guidance content CNT2 is superposed on the correct superimposing target, and can exert the function of presenting information for guiding the continuous point P2 with high certainty.

Further, in the present embodiment, the situation where the display start timing of the guidance content CNT2 is delayed is also reduced. According to the above, it becomes easy to secure the time for recognizing the continuous point P2, so that the driver can smoothly perform the recognition at the continuous guide points.

In addition, in the present embodiment, after the start of a right turn or a left turn at the right / left turn point P1, the vehicle A travels by using the detection information of the lane marking line or the road end of the connecting road Rc by the front camera 31 mounted on the vehicle A. Directional determination is performed. Therefore, the vehicle posture determination unit 77 can grasp the direction of the vehicle A with respect to the connecting road Rc in real time and determine the display start timing of the guidance content CNT2. Based on the above, it is possible to improve the accuracy of the straight-ahead determination of the vehicle A and further reduce the risk of erroneous recognition of route guidance.

Further, in the present embodiment, after the start of the right turn or the left turn at the right / left turn point P1, the traveling direction of the vehicle A is determined by using the map data and the direction information based on the positioning signal. Therefore, the vehicle posture determination unit 77 can grasp the direction of the vehicle A with respect to the connecting road Rc and determine the display start timing of the guidance content CNT2 even if the connecting road Rc is in a mode in which it is difficult to detect the lane marking and the road end. .. Based on the above, since the straight-ahead determination can be performed without depending on the road environment, the possibility of erroneous recognition of route guidance can be reduced in many driving scenes.

Further, in the present embodiment, after the start of the right turn or the left turn at the right / left turn point P1, the traveling direction of the vehicle A is determined by using the steering angle information. If the end of the turn of the vehicle A can be grasped by using the own vehicle information in this way, the vehicle posture determination unit 77 can determine the display start timing of the guidance content CNT2 without being affected by the external environment of the vehicle A. Based on the above, it is possible to reduce the risk of erroneous recognition of route guidance in more driving scenes.

In addition, in the present embodiment, as shown in FIG. 9, when there is no obstruction BO (see FIG. 6) in the roadside area of the connecting road Rc, the display start of the guidance content CNT2 is accelerated. In such a scene, even if the superimposition display of the guidance content CNT2 is started at an early stage, the superimposition on the superimposition target does not occur, so that the possibility of erroneous recognition can be substantially eliminated. Therefore, according to the process of accelerating the display start of the guidance content CNT2 based on the absence of the shield BO, it is possible to obtain the merit that the driver recognizes the continuous point P2 at an early stage.

Further, in the present embodiment, when the superimposing target of the guidance content CNT2 guided at the continuous point P2 is in the roadside area of the connecting road Rc, the determination criteria for straight-ahead determination is relaxed as compared with the case where the superimposing target is in the road surface area. NS. According to such adjustment, in the case where the continuous point P2 is the destination or the like, the guidance content CNT2 can be superimposed on the building or the like in the roadside area which is the goal point at an early stage. Therefore, the recognition of the continuous point P2 by the driver can also be performed at an early stage.

In the above embodiment, the navigation map data and the high-precision map data correspond to "map information", the front camera 31 corresponds to the "outside world sensor", and the display generation unit 78 corresponds to the "display control unit". The shield BO corresponds to a "specific object". Further, the continuous point P2 corresponds to the "sequential guidance point", the connecting road Rc corresponds to the "road", and the HCU 100 corresponds to the "display control device".

In the first modification of the embodiment, the continuous guidance determination unit 75 performs the following determination as to whether or not the plurality of guidance points are continuous, instead of the navigation ECU 52. Specifically, the continuous guidance determination unit 75 refers to the route information provided by the navigation ECU 52, and calculates the distance between the right / left turn point P1 and the continuous point P2 lined up on the set route indicated by the route information. When the distance between these two points arranged on the set path is shorter than the threshold distance, the continuous guidance determination unit 75 determines that the right / left turn point P1 and the continuous point P2 are continuous, that is, there is continuous information. .. In the continuous guidance determination unit 75, the threshold distance used for the continuous determination is set to, for example, about several hundred to 1000 m. The threshold distance may be adjustable by the user of the vehicle A such as a driver, or may be automatically adjusted according to the type of the continuous point P2.
