DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] An example of an embodiment of the present invention will be described in detail below with reference to the drawings. Fig. 1 is a diagram showing a schematic configuration of a vehicle display device according to this embodiment. Note that the arrow UP in Fig. 1 indicates the upper side in the vertical direction of the vehicle, and the arrow RH indicates the right side in the width direction of the vehicle. The vertical direction and the left-right direction in the following description respectively mean the up-down direction in the vertical direction of the vehicle and the left-right direction in the width direction of the vehicle.

[0025] 1, an instrument panel 70 is provided at the front of the passenger compartment of the vehicle 10. The instrument panel 70 extends in the vehicle width direction, and a steering wheel 72 is provided on the right side of the instrument panel 70. That is, in this embodiment, as an example, the vehicle is a right-hand drive vehicle in which the steering wheel 72 is provided on the right side, and the driver's seat is located on the right side of the vehicle.

[0026] A windshield glass 74 is provided at the front end of the instrument panel 70. The windshield glass 74 extends in the vehicle vertical direction and in the vehicle width direction, and separates the inside and outside of the vehicle compartment.

[0027] The right end of the windshield glass 74 is fixed to a front pillar 76 on the right side of the vehicle. The front pillar 76 extends in the vertical direction of the vehicle, and the windshield glass 74 is fixed to the inner end in the vehicle width direction of the front pillar 76. The left end of the windshield glass 74 is fixed to a front pillar on the left side of the vehicle (not shown).

[0028] The windshield glass 74 is provided with a display area 14 that displays an image in front of the occupant. The display area 14 is a projection surface onto which an image is projected by a display unit 18 (see FIG. 2). In other words, the display unit 18 is a head-up display device provided on the vehicle front side of the instrument panel 70. The display unit 18, which is a head-up display device, is configured to project an image onto the display area 14 of the windshield glass 74.

[0029] Next, a description will be given of the configuration of a control system of the vehicle display device 12 according to this embodiment. Fig. 2 is a block diagram showing the configuration of the control system of the vehicle display device 12 according to this embodiment.

[0030] The vehicle display device 12 according to this embodiment includes a meter ECU (Electronic Control Unit) 16, a positioning sensor 22, a vehicle speed sensor 24, an acceleration sensor 26, a gyro sensor 28, and a multimedia display ECU 20, each of which is connected to a vehicle network 30.

[0031] The meter ECU 16 is connected to a display unit 18 and controls the display unit 18 to display an image in the display area 14 .

[0032] The positioning sensor 22 measures the position of the vehicle 10 by receiving, for example, Global Navigation Satellite System (GNSS) signals including time information from a plurality of GNSS satellites.

[0033] The vehicle speed sensor 24 detects the vehicle speed, the acceleration sensor 26 detects the acceleration generated in the vehicle 10, and the gyro sensor 28 detects changes in the rotation, orientation, etc. of the vehicle 10 as angular velocity. Note that a yaw rate sensor may be applied instead of the gyro sensor 28, and a configuration may also be adopted that further includes a yaw rate sensor.

[0034] The multimedia display ECU 20 has a function of a navigation device that displays guidance to a preset destination based on the detection results of each sensor, such as the positioning sensor 22, the vehicle speed sensor 24, the acceleration sensor 26, and the gyro sensor 28. For example, the multimedia display ECU 20 determines the relative trajectory of the vehicle 10 based on the detection results of each sensor, and performs processing such as map matching with a previously created map.

[0035] 3 is a block diagram showing the configuration of the main parts of the electrical system of the meter ECU 16 and the multimedia display ECU 20 in the vehicle display device 12 according to this embodiment. Since the meter ECU 16 and the multimedia display ECU 20 are basically configured as general computers, the meter ECU 16 will be described here as a representative example.

[0036] The meter ECU 16 is configured with a general microcomputer including a CPU (Central Processing Unit) 16A, a ROM (Read Only Memory) 16B, a RAM (Random Access Memory) 16C, a storage 16D, an interface (I / F) 16E, and a bus 16F.

[0037] The CPU 16A is a central processing unit, and controls the overall operation of the device by executing various programs. The ROM 16B stores various control programs, various parameters, etc. in advance. The RAM 16C is used as a work area when the CPU 16A executes various programs. The storage 16D is composed of various storage units such as a hard disk drive (HDD), a solid state drive (SSD), and a flash memory, and stores various data, application programs, etc. The I / F 16E is connectable to a vehicle network 30, and transmits and receives various data to and from other ECUs such as the meter ECU 16 connected to the vehicle network 30. The above-mentioned units of the meter ECU 16 are electrically connected to each other by a bus 16F.

[0038] Next, a description will be given of a functional configuration that functions as a result of the CPU 16A of the meter ECU 16 executing a program stored in the ROM 16B.

[0039] The meter ECU 16 has the functions of a position acquisition unit 32, a node information acquisition unit 34, a correction unit 36, and a display control unit 38.

[0040] The position acquisition unit 32 acquires the current positioning result of the positioning sensor 22 and the previous positioning result of the positioning sensor 22 from the multimedia display ECU 20 and outputs them to the correction unit 36 ​​.

[0041] The node information acquisition unit 34 acquires information on the guidance intersection and the immediately preceding node from the multimedia display ECU 20 and outputs the information to the correction unit 36 ​​.

[0042] The correction unit 36 ​​corrects the positional relationship of the vehicle 10 on a map created in advance to the actual positional relationship of the vehicle 10. For example, the correction unit 36 ​​corrects the virtual relative relationship between a virtual route on the map along which the vehicle 10 travels and a virtual traveling direction of the vehicle 10 on the map to an actual relative relationship between an actual traveling route on which the vehicle 10 actually travels and an actual traveling direction of the vehicle 10. Specifically, the correction unit 36 ​​compares the traveling direction of the vehicle 10 calculated from the position of the vehicle 10 acquired by the position acquisition unit 32 with the extension direction of a virtual line connecting shape points on the map to correct the virtual relative relationship.

[0043] Based on the correction result by the correction unit 36, the display control unit 38 controls the display unit 18 to display an arrow image 40 as a direction image indicating the traveling direction of the vehicle 10 to be displayed in the display area 14, as shown in Fig. 5. That is, since the arrow image 40 is displayed superimposed on the actual intersection, it becomes easy to confirm both the lane change position and the lane change direction.

[0044] Incidentally, when an arrow image 40 is displayed as a direction image indicating the traveling direction as shown in Fig. 5, the arrow image 40 is displayed in the display area 14 so as to indicate a direction derived from a virtual route on a map at a lane change position. However, if the arrow image 40 is not displayed in accordance with the actual direction of the vehicle 10, the direction of the arrow image 40 may deviate from the direction of the actual intersection as shown in Fig. 6.

[0045] Therefore, in this embodiment, the correction unit 36 ​​corrects the positional relationship of the vehicle 10 on the map created in advance to the actual positional relationship of the vehicle 10. This makes it possible to suppress deviation of the direction of the arrow image 40 from the actual traveling direction.

[0046] Here, the correction by the correction unit 36 ​​will be described in detail with reference to Figs. 7 to 9. Fig. 7 is a diagram for explaining the calculation of the angle of the virtual traveling direction of the vehicle 10 on the map with respect to the north as a reference. Fig. 8 is a diagram for explaining the calculation of the angle of the actual traveling direction of the vehicle 10 with respect to the north as a reference. Fig. 9 is a diagram for explaining the calculation of the angle of the vehicle 10 with respect to the traveling direction of the vehicle 10 while traveling.

[0047] First, the correction unit 36 ​​obtains the entry angle of the vehicle at the guidance intersection. Specifically, as shown in FIG. 7, the correction unit 36 ​​uses node information of the guidance intersection and the immediately preceding node as a shape point to calculate the entry angle A of the vehicle at the guidance intersection with respect to north. That is, the virtual traveling direction on the map is obtained, and the angle A with respect to north as a reference is calculated. In the example of FIG. 7, the extension direction (link direction in FIG. 7) of the virtual line connecting the node N3 of the guidance intersection and the immediately preceding node N2, and the angle A with respect to north as a reference are calculated. Note that the nodes as shape points represent each point such as latitude and longitude on a road or the like on a map. The extension direction of the node may also be referred to as the link direction.

[0048] The correction unit 36 ​​also obtains the angle of the vehicle with respect to the north as a reference. Specifically, as shown in Fig. 8, the latitude and longitude of the current time and before the previous map matching are used to calculate the angle B of the vehicle position with respect to the north. That is, the detection result of the positioning sensor 22 is used to obtain the traveling direction of the vehicle, and the angle B with respect to the north as a reference is calculated. Note that the angle B is updated only when the vehicle speed is equal to or greater than a predetermined vehicle speed S [km / h] and the distance between the vehicle position and the guidance intersection (node ​​N3) is narrowed by equal to or greater than a predetermined distance D [m].

[0049] Then, as shown in FIG. 9, the correction unit 36 ​​calculates the corrected angle C of the vehicle using the angle A and the angle B obtained by using the node information of the guidance intersection and the latitude and longitude before map matching. In detail, the correction unit 36 ​​calculates the vehicle angle C based on the currently traveling link direction = the vehicle's entry angle A of the guidance intersection - the vehicle's angle B with respect to the north. As a result, the correction unit 36 ​​compares the traveling direction of the vehicle 10 with the extending direction of the virtual line connecting the nodes (shape points) on the map, and calculates a correction value for correcting the virtual relative relationship between the virtual route on which the vehicle 10 travels on the map and the virtual traveling direction of the vehicle 10 on the map to the actual relative relationship between the actual traveling route on which the vehicle 10 actually travels and the actual traveling direction of the vehicle 10. By correcting the angle of the arrow image 40 by using the calculated correction value when the display control unit 38 displays the arrow image 40, it is possible to suppress the deviation of the angle of the arrow image 40 at the lane change position such as an actual intersection.

[0050] Next, the process performed by the meter ECU 16 of the vehicle display device 12 according to the present embodiment configured as described above will be described. Fig. 10 is a flow chart showing an example of the flow of the process performed by the meter ECU 16 of the vehicle display device 12 according to the present embodiment. The process of Fig. 10 is started, for example, when the distance to the guidance intersection is within a predetermined distance.

[0051] In step 100, the CPU 16A acquires information on the guidance intersection and the node immediately preceding the guidance intersection, and the process proceeds to step 102. That is, the node information acquisition unit 34 acquires information on the guidance intersection and the node immediately preceding the guidance intersection from the multimedia display ECU 20.

[0052] In step 102, the CPU 16A calculates the vehicle entry angle A with respect to the reference, and proceeds to step 104. That is, the correction unit 36 ​​calculates the entry angle A of the vehicle 10 on the map with respect to the north, as shown in Fig. 7. For example, in the example of Fig. 7, the angle A with respect to the extension direction (link direction in Fig. 7) of a virtual line connecting the node N3 of the guidance intersection and the immediately preceding node N2 is calculated.

[0053] In step 104, the CPU 16A acquires the current and previous positioning results, and proceeds to step 106. That is, the position acquisition unit 32 acquires the current positioning result of the positioning sensor 22 and the previous positioning result of the positioning sensor 22 from the multimedia display ECU 20.

[0054] In step 106, the CPU 16A calculates an angle B of the vehicle position with respect to a reference, and proceeds to step 108. That is, as shown in Fig. 8, the correction unit 36 ​​uses the detection result of the positioning sensor 22 to obtain the traveling direction of the vehicle, and calculates the angle B with respect to north as a reference.

[0055] In step 108, the CPU 16A calculates the angle C of the vehicle with respect to the currently traveling link as a reference, and proceeds to step 110. That is, the correction unit 36 ​​calculates the angle C of the vehicle shown in Fig. 9 by using the angle C of the vehicle with respect to the currently traveling link direction as a reference = the vehicle entry angle A of the guidance intersection - the angle B of the vehicle relative to the north.

[0056] In step 110, the CPU 16A displays the arrow image 40 in the display area 14 and proceeds to step 112. That is, the display control unit 38 controls the display unit 18 to display the arrow image 40 in the display area 14, as shown in Fig. 9. When displaying the arrow image 40, the angle of the arrow is corrected using the angle C of the vehicle calculated in step 108, thereby suppressing deviation in the angle of the arrow image 40 at an actual lane change position such as an intersection.

[0057] In step 112, the CPU 16A determines whether or not to update the angle B. For example, the CPU 16A determines whether or not the vehicle speed is equal to or greater than a predetermined vehicle speed S [km / h] and the distance between the vehicle position and the guidance intersection (node ​​N3) has narrowed by a predetermined distance D [m] or more. If the determination is positive, the CPU 16A returns to step 104 to repeat the above-mentioned process, and if the determination is negative, the CPU 16A proceeds to step 114.

[0058] In step 114, the CPU 16A judges whether or not the guidance intersection has been passed. If the judgment is negative, the process returns to step 112 to repeat the above-mentioned processing. If the judgment is positive, the process proceeds to step .

[0059] In step 116, the CPU 16A makes the arrow image 40 displayed in the display area 14 non-display, and ends the series of processes.

[0060] By performing the process in this manner, the correction unit 36 ​​can calculate a correction value for correcting the virtual relative relationship between the virtual route along which the vehicle 10 travels on the map and the virtual traveling direction of the vehicle 10 on the map to the actual relative relationship between the actual traveling route along which the vehicle 10 actually travels and the actual traveling direction of the vehicle 10. Then, the display control unit 38 uses the calculated correction value to correct the angle of the arrow image 40 when displaying the arrow image 40, thereby suppressing deviation in the angle of the arrow image 40 at a lane change position such as an actual intersection.

[0061] In the above embodiment, the arrow image 40 is displayed at the lane change position, but the present invention is not limited to this. For example, as shown in Fig. 11, after the arrow image 40 is displayed to move toward the lane change position, when the lane change position detected from the captured image of the front is within the angle of view, the arrow image 40 may be displayed at the lane change position.

[0062] In addition, the processing performed by the vehicle display device 12 in each of the above embodiments has been described as software processing performed by executing a program, but is not limited to this. For example, the processing may be performed by hardware such as a GPU (Graphics Processing Unit), an ASIC (Application Specific Integrated Circuit), and an FPGA (Field-Programmable Gate Array). Alternatively, the processing may be a combination of both software and hardware. In addition, when the processing is performed by software, the program may be stored in various storage media and distributed.

[0063] Furthermore, the present invention is not limited to the above, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
