DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] 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.

[0026] 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.

[0027] A windshield glass 74 is provided at the front end of the instrument panel 70. The windshield glass 74 extends in the vertical direction and the width direction of the vehicle, and separates the inside and outside of the vehicle compartment.

[0028] 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).

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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 .

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Next, a description will be given of the functional configuration that functions as the CPUs 16A, 20A of the meter ECU 16 and the multimedia display ECU 20 execute programs stored in the ROMs 16B, 20B. FIG. 4 is a functional block diagram showing the functional configuration of the meter ECU 16 and the multimedia display ECU 20.

[0040] The multimedia display ECU 20 has the functions of a position acquisition unit 32, a map acquisition unit 34, and a position accuracy calculation unit 36, and the meter ECU 16 has the function of a display change unit 38. Note that there are cases where the multimedia display ECU 20 and the meter ECU 16 correspond to a vehicle display control device, and cases where the meter ECU 16 corresponds to a vehicle display control device.

[0041] The position acquisition unit 32 acquires the detection results of the positioning sensor 22, the vehicle speed sensor 24, the acceleration sensor 26, and the gyro sensor 28 as position information of the vehicle 10, and outputs it to a position accuracy calculation unit .

[0042] The map acquisition unit 34 acquires map information that has been created in advance and stored in the storage 20D or the like, and outputs it to the position accuracy calculation unit 36. Note that the map information may be stored externally, such as in a map server, and the map information may be acquired from the outside.

[0043] The position accuracy calculation unit 36 ​​obtains the relative trajectory of the vehicle 10 based on the position information of the vehicle 10 acquired by the position acquisition unit 32 and the map information acquired by the map acquisition unit 34. Then, the position accuracy calculation unit 36 ​​estimates the position of the vehicle 10 by performing map matching to match the position of the vehicle 10 on the map using the position information of the vehicle 10 and the map information, and calculates the accuracy of the detected position of the vehicle 10. The accuracy of the detected position corresponds to the degree of agreement between the actual position of the vehicle 10 and the virtual position on the map, and is calculated based on the actual position detected by the positioning sensor 22 and the virtual position of the vehicle 10 on the map. As the accuracy of the detected position to be calculated, for example, the map matching accuracy, the horizontal accuracy degradation rate, and the vertical accuracy degradation rate are calculated by using well-known techniques.

[0044] The display change unit 38 performs a process of changing the information that the display unit 18 displays in the display area 14 according to the accuracy of the detected position calculated by the position accuracy calculation unit 36. In this embodiment, when the map matching accuracy, the horizontal accuracy degradation rate, and the vertical accuracy degradation rate are each equal to or higher than a predetermined accuracy, as shown in FIG. 5, an arrow image 40 is displayed in the display area 14 as an image indicating the route at the route change position. In addition to the arrow image 40, as shown in FIG. 5, the intersection name, the remaining distance to the intersection that is the route change position, the speed, etc. may be displayed. Note that the arrow image 40 may be displayed in the display area 14 by recognizing the intersection by image recognition based on an image captured by a camera or the like of the front, for example, and when the guidance intersection comes within the angle of view.

[0045] On the other hand, if any of the map matching accuracy, the horizontal accuracy degradation rate, and the vertical accuracy degradation rate does not satisfy a predetermined accuracy, the arrow image 40 is not displayed, and the remaining distance to the lane change position is displayed in the display area 14, as shown in Fig. 6. In addition to the remaining distance, the intersection name and the speed may be displayed, as shown in Fig. 6.

[0046] Next, the processes performed by the multimedia display ECU 20 and the meter ECU 16 of the vehicle display device 12 according to this embodiment configured as described above will be described.

[0047] First, the process performed by the multimedia display ECU 20 will be described. Fig. 7 is a flowchart showing an example of the flow of the process performed by the multimedia display ECU 20 of the vehicle display device 12 according to this embodiment. The process in Fig. 7 starts, for example, when an ignition switch (not shown) is turned on.

[0048] In step 100, the CPU 20A acquires the detection results of the sensors and proceeds to step 102. That is, the position acquisition unit 32 acquires the detection results of each of the sensors, the positioning sensor 22, the vehicle speed sensor 24, the acceleration sensor 26, and the gyro sensor 28, as information for detecting the position of the vehicle 10.

[0049] In step 102, the CPU 20A acquires map information and proceeds to step 104. That is, the map acquisition unit 34 acquires map information that has been created in advance and stored in the storage 20D or the like. As the map information to be acquired, map information of a predetermined range including the position of the vehicle 10 detected by the positioning sensor 22 is acquired.

[0050] In step 104, the CPU 20A derives the relative trajectory of the vehicle, and proceeds to step 106. That is, the position accuracy calculation unit 36 ​​determines the relative trajectory of the vehicle 10 based on the position information of the vehicle 10 acquired by the position acquisition unit 32 and the map information acquired by the map acquisition unit 34.

[0051] In step 106, the CPU 20A performs map matching, and proceeds to step 108. That is, the position accuracy calculation unit 36 ​​performs map matching to align the position of the vehicle 10 on the map, using information detecting the position of the vehicle 10 and map information.

[0052] In step 108, the CPU 20A calculates the accuracy of the detected position of the vehicle 10, and proceeds to step 110. That is, the position accuracy calculation unit 36 ​​calculates the map matching accuracy, the horizontal accuracy degradation rate, and the vertical accuracy degradation rate by well-known techniques.

[0053] In step 110, the CPU 20A judges whether or not to end the process. For example, the CPU 20A judges whether or not an ignition switch (not shown) has been turned off, or whether or not an operation to turn off the map display has been performed. If the judgment is negative, the CPU 20A returns to step 100 and repeats the above-mentioned process, and if the judgment is positive, the CPU 20A ends the series of processes.

[0054] Next, a process performed by the meter ECU 16 will be described. Fig. 8 is a flowchart 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 in Fig. 8 is performed, for example, when a destination is set by an occupant of the vehicle 10 and guidance is started.

[0055] In step 200, the CPU 16A acquires the accuracy of the detected position of the vehicle 10, and proceeds to step 202. That is, the CPU 16A acquires the accuracy of the detected position of the vehicle 10 calculated by the multimedia display ECU 20 in the above-mentioned step 108, and proceeds to step 202. Note that step 200 corresponds to an acquisition unit.

[0056] In step 202, the CPU 16A judges whether the accuracy of the detected position of the vehicle 10 is equal to or higher than a predetermined accuracy. This judgement is made by the display change unit 38 judging whether the map matching accuracy, the horizontal accuracy degradation rate, and the vertical accuracy degradation rate are each equal to or higher than a predetermined accuracy. If the judgement is affirmative, the process proceeds to step 204, and if any of them does not meet the predetermined accuracy, the judgement is negative and the process proceeds to step 206.

[0057] In step 204, the CPU 16A performs guidance display processing with an arrow image and proceeds to step 208. For example, as shown in Fig. 5, an arrow image 40 is displayed as an image indicating the route in the display area 14 at the lane change position. As a result, the arrow image 40 is displayed superimposed on the actual lane change position such as an intersection, so that it can be recognized that the position of the arrow image 40 is the lane change position.

[0058] On the other hand, in step 206, the CPU 16A performs guidance display processing without an arrow image, and proceeds to step 208. For example, as shown in Fig. 6, the arrow image 40 is not displayed, and the remaining distance to the lane change position is displayed in the display area 14. This makes it possible to prevent the arrow image 40 from being displayed in an incorrect position when the accuracy of the detected position of the detected vehicle does not meet a predetermined accuracy.

[0059] In step 208, the CPU 16A judges whether the guidance has ended. If the judgment is negative, the process returns to step 200 to repeat the above-mentioned processing, and if the judgment is positive, the series of processing is ended.

[0060] In this way, the meter ECU 16 performs a process of changing the information that the display unit 18 displays in the display area 14 according to the accuracy of the detected position of the vehicle 10 calculated by the multimedia display ECU 20. This makes it possible to display appropriate information to the occupant according to the accuracy of the vehicle position detection.

[0061] Specifically, when the accuracy of the detected position of the vehicle 10 is equal to or greater than a predetermined accuracy, an arrow image is displayed in the display area 14, and when the accuracy does not meet the predetermined level, the remaining distance to the lane change position is displayed without displaying the arrow image 40, thereby preventing the arrow image from being displayed in the wrong position when the accuracy of the detected position is low.

[0062] In the above embodiment, an example has been described in which the arrow image 40 is changed to be displayed or not displayed depending on the accuracy of the position detection of the vehicle 10, but the change of the image to be displayed is not limited to this. For example, when the accuracy of the position detection of the vehicle 10 is equal to or higher than a predetermined accuracy, the arrow image 40 may be displayed in the display area 14 as in the above embodiment, and when the accuracy does not meet the predetermined accuracy, a simple map image 42 may be displayed in the display area 14 as shown in FIG. 9.

[0063] Alternatively, a plurality of thresholds for the accuracy of the detected position of the vehicle 10 may be provided, and the display may be changed to, for example, those shown in Figures 5, 6, and 9. When the displays in Figures 5, 6, and 9 are used, the display may be changed, for example, in descending order of the accuracy of the detected position of the vehicle 10 to the arrow image 40 in Figure 5, the simple map image 42 in Figure 9, and the remaining distance in Figure 6.

[0064] In the above embodiment, an example has been described in which the information displayed in the display area 14 is changed depending on the degree of coincidence between the actual position of the vehicle 10 and the virtual position of the vehicle 10 on the map, but the present invention is not limited to this. For example, the information displayed in the display area 14 may be changed depending on the distance between the virtual position of the vehicle 10 on the map and the virtual position of the vehicle 10 on the map. Specifically, when the distance between the actual position and the virtual position is less than a predetermined threshold, an arrow image 40 may be displayed, and when the distance is equal to or greater than the threshold, at least one of the remaining distance to the lane change position and the simple map 42 may be displayed.

[0065] In the above embodiment, the two ECUs, the multimedia display ECU 20 and the meter ECU 16, perform the processes shown in Figures 7 and 8. However, the number of ECUs is not limited to two. For example, the processes shown in Figures 7 and 8 may be performed by one ECU, or three or more ECUs may perform the processes in cooperation with each other.

[0066] 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. 10, the arrow image 40 may be displayed so as to move toward the lane change position, and then when the lane change position comes within the angle of view, the arrow image 40 may be displayed at the lane change position.

[0067] In addition, the processes performed by the multimedia display ECU 20 and the meter ECU 16 in each of the above embodiments have been described as software processes performed by executing a program, but the present invention is not limited to this. For example, the processes 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 processes may be a combination of both software and hardware. In the case of software processes, the programs may be stored in various storage media and distributed.

[0068] 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]
