[Modes for carrying out the invention]

[0024] Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. Figure 1 is a schematic diagram of a vehicle display device according to this embodiment. In Figure 1, the arrow UP indicates the upper side in the vehicle's vertical direction, and the arrow RH indicates the right side in the vehicle's width direction. In the following description, the vertical direction and the left-right direction refer to the vertical direction of the vehicle and the left-right direction in the vehicle's width direction, respectively.

[0025] As shown in Figure 1, an instrument panel 70 is provided at the front of the passenger compartment of the vehicle 10. A windshield glass 74 is provided at the front end of the instrument panel 70. The windshield glass 74 extends in the vertical and horizontal directions of the vehicle, separating the interior of the passenger compartment from the exterior.

[0026] The right-side end of the windshield glass 74 is fixed to the right-side front pillar 76 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 of this front pillar 76 in the vehicle width direction. The left-side end of the windshield glass 74 is fixed to the left-side front pillar of the vehicle (not shown).

[0027] 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. In other words, in this embodiment, as an example, it is a right-hand drive vehicle with the steering wheel 72 on the right side, and the driver's seat is set on the right side of the vehicle.

[0028] A display 14 for the vehicle is provided in the instrument panel 70 at a position corresponding to the front of the steering wheel 72. The display 14 is, for example, made up of a liquid crystal panel and displays the vehicle's driving status, the operating status of driver assistance systems, etc.

[0029] Next, the configuration of the control system of the vehicle display device 12 according to this embodiment will be described. Figure 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 driving state detection sensor 18, a surrounding conditions monitoring device 20, and an advanced driver assistance ECU 22, each of which is connected to the vehicle network 24.

[0031] The meter ECU 16 is connected to a display 14, which controls the display 14 to perform processes such as displaying multiple meters and displaying various vehicle information. Furthermore, if a vehicle malfunction occurs, the meter ECU 16 notifies the occupant by displaying the malfunction on the display 14. Examples of vehicle information displayed on the display 14 include the operating status of driver assistance systems. The display mode of the display 14 can be switched using a switch (not shown), allowing the driver to change the display mode according to their preference.

[0032] The driving state detection sensor 18 detects the driving state of the vehicle 10. The driving state detection sensor 18 includes, for example, at least one sensor from among various sensors such as a vehicle speed sensor, an acceleration sensor, a gyro sensor, an accelerator pedal position sensor, and a brake sensor.

[0033] The surrounding environment monitoring device 20 detects information that represents the conditions of the environment surrounding the vehicle. For example, it includes at least one device from among various devices such as a GPS (Global Positioning System) device, an in-vehicle communication device, a navigation system, a radar device, and a camera.

[0034] The advanced driver assistance ECU 22 acquires surrounding information detected by the surrounding situation monitoring device 20, which monitors the surroundings, and has the function of providing surrounding information to other ECUs and controlling the steering and brakes when necessary. For example, when the driving state detection sensor 18 detects that the accelerator has been released and the surrounding situation monitoring device 20 detects a vehicle ahead or an intersection, the advanced driver assistance ECU 22 controls the brakes to assist in deceleration. Specifically, the advanced driver assistance ECU 22 controls functions such as cruise control, which follows the speed of the preceding vehicle and controls acceleration and deceleration, and lane tracing assist, which warns of the possibility of deviating from the lane or road and assists in some steering operations to avoid deviating from the lane or road. In this embodiment, there are two types of cruise control functions: normal cruise control that maintains a set speed, and eco-driving cruise control that reduces fuel consumption by performing pulse-and-glide driving at a preset speed. Pulse-and-glide driving is a driving method that repeatedly accelerates and coasts in order to reduce fuel consumption while driving. In addition, the eco-driving cruise control performs pulse-and-glide driving to maintain a predetermined acceptable speed range, with a pre-set speed as the upper limit.

[0035] Figure 3 is a block diagram showing the main electrical system configurations of the meter ECU 16 and the advanced driver assistance ECU 22 in the vehicle display device 12 according to this embodiment. Note that the meter ECU 16 and the advanced driver assistance ECU 22 are basically configured as general-purpose computers, so the meter ECU 16 will be described as a representative example here.

[0036] The meter ECU16 consists of a general-purpose microcomputer including a CPU (Central Processing Unit) 16A, ROM (Read Only Memory) 16B, RAM (Random Access Memory) 16C, storage 16D, interface (I / F) 16E, and bus 16F.

[0037] The CPU 16A is a central processing unit that controls the overall operation of the device by executing various programs. The ROM 16B stores various control programs such as vehicle display programs and various parameters 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 HDD (Hard Disk Drive), SSD (Solid State Drive), and flash memory, and stores various data and application programs. The I / F 16E is connectable to the vehicle network 24 and transmits and receives various data with other ECUs such as the meter ECU 16 that are connected to the vehicle network 24. The various parts of the meter ECU 16 are electrically interconnected by the bus 16F. In this embodiment, the vehicle display program is described as being stored in the ROM 16B, but it may also be stored in the storage 16D.

[0038] Next, we will describe the functional configuration of the meter ECU16, which operates by the CPU16A executing the program stored in the ROM16B. Figure 4 is a functional block diagram showing the functional configuration of the meter ECU16.

[0039] As shown in Figure 4, the meter ECU 16 has the functions of an acquisition unit 26 and a control unit 28 when the CPU 16A executes a program stored in the ROM 16B.

[0040] When eco-driving cruise control is instructed, the acquisition unit 26 acquires the status of pulse and glide driving assistance from the advanced driver assistance ECU 22.

[0041] The control unit 28 displays a status image on the display 14 that represents the acceleration state or coasting state due to driving assistance and an indicator of the end of the state, based on the acquisition results from the acquisition unit 26. In other words, the control unit 28 performs the process of displaying a status image on the display 14 that represents the acceleration state or coasting state due to driving assistance and an indicator of the end of the state, based on the state of driving assistance for pulse and glide driving acquired by the acquisition unit 26.

[0042] Next, we will explain the display control on the display 14, which is performed by the CPU 16A of the meter ECU 16 executing a program stored in the ROM 16B.

[0043] The meter ECU 16 controls the display 14 to show the detection results of the driving condition detection sensor 18 and the detection results of the surrounding condition monitoring device 20. The meter ECU 16 also controls the display to show the assistance status provided by the advanced driver assistance ECU 22.

[0044] For example, as shown in Figure 5(A), the display 14 shows images representing the temperature, vehicle speed, water temperature, fuel level, etc., as an example of the detection results of the driving condition detection sensor 18, and displays information such as other vehicles around the vehicle 10 as an example of the detection results of the surrounding situation monitoring device 20. Images representing the driving assistance functions in operation are also displayed. In Figure 5(A), the temperature ("75°F" in Figure 5(A)) and vehicle speed ("100MPH" in Figure 5(A)) are displayed numerically, the water temperature and fuel level are displayed as a water temperature gauge image 30 and a fuel gauge image 32, the water temperature and fuel level are displayed as a water temperature gauge image 30 and a fuel level gauge image 32, an image of the own vehicle 34 is displayed along with an image of other vehicles 36 indicating the presence of vehicles in front and to the side, and an icon 38 indicating that the eco-driving cruise control function is in operation and an icon 40 indicating that the lane tracing assist function is in operation are displayed.

[0045] By the way, in a vehicle 10 equipped with the vehicle display device 12 according to this embodiment, when the eco-driving cruise control function is being executed by the advanced driver assistance ECU 22, the status of the pulse-and-glide driving assistance may not be known.

[0046] Therefore, the vehicle display device 12 according to this embodiment performs control to display a status image that represents the acceleration state or coasting state by the advanced driver assistance ECU 22 when the eco-driving cruise control function is being executed, and an indicator of the end of each state.

[0047] For example, as shown in Figures 5(A) and (B), in the case of pulse-and-glide driving using eco-driving cruise control, the vehicle image 34 and line images 42 in front of and behind the vehicle image 34 are displayed as status images. Then, in the coasting state of pulse-and-glide driving, as shown in Figure 5(A), the line image 42 behind the vehicle image 34 is highlighted (for example, by displaying a thick line or a gradient), and the relative position of the line image 42 and the vehicle image 34 is changed to indicate the end of the coasting state. For example, as the vehicle approaches a predetermined allowable speed through coasting, the distance between the line image 42 behind the vehicle image 34 and the vehicle image 34 is displayed to shorten. Also, in the acceleration state of pulse-and-glide driving, as shown in Figure 5(B), the line image 42 in front of the vehicle image 34 is highlighted (for example, by displaying a thick line or a gradient), and the relative position of the line image 42 and the vehicle image 34 is changed to indicate the end of the coasting state. For example, as the vehicle accelerates and approaches a predetermined speed, the distance between the line image 42 in front of the vehicle image 34 and the vehicle image 34 is displayed to decrease.

[0048] Next, we will describe the specific processing performed by the meter ECU 16 of the vehicle display device 12 according to this embodiment, which is configured as described above. Figure 6 is a flowchart showing an example of the processing flow performed by the meter ECU 16 of the vehicle display device 12 according to this embodiment. Note that the processing in Figure 6 is started, for example, when the advanced driver assistance ECU 22 instructs the start of the eco-driving cruise control function.

[0049] In step 100, the CPU 16A acquires the driving assistance status for pulse and glide driving and proceeds to step 102. Specifically, the acquisition unit 26 acquires the driving assistance status for pulse and glide driving of the eco-driving cruise control from the advanced driver assistance ECU 22.

[0050] In step 102, the CPU 16A determines whether or not acceleration is in progress. This determination determines whether or not the driving assistance state for pulse and glide driving is in the acceleration phase. If the determination is affirmative, the process proceeds to step 104; otherwise, the process proceeds to step 106.

[0051] In step 104, the CPU 16A displays an acceleration state image on the display 14 and proceeds to step 106. For example, as shown in Figure 5(B), the self-vehicle image 34 and line images 42 in front of and behind the self-vehicle image 34 are displayed as a state image. The line image 42 in front of the self-vehicle image 34 is highlighted (for example, by displaying a thick line or a gradient), and the relative position of the self-vehicle image 34 between the line images 42 is changed to indicate the end of the coasting state. For example, as the acceleration approaches a predetermined speed, the distance between the line image 42 in front of the self-vehicle image 34 and the self-vehicle image 34 is displayed to shorten. This allows the occupant to recognize that the vehicle is accelerating due to the eco-driving cruise control. At this time, the change in the relative position of the self-vehicle image 34 between the line images 42 also allows the occupant to recognize the end of the acceleration state.

[0052] In step 106, the CPU 16A determines whether or not the vehicle is coasting. This determination determines whether or not the driving assistance state for pulse-and-glide driving is coasting. If the determination is affirmative, the system proceeds to step 108; otherwise, it proceeds to step 110.

[0053] In step 108, the CPU 16A displays a state image of the coasting state on the display 14 and proceeds to step 110. For example, as shown in Figure 5(A), the self-vehicle image 34 and line images 42 in front of and behind the self-vehicle image 34 are displayed as a state image. The line image 42 behind the self-vehicle image 34 is highlighted (for example, by displaying a thick line or a gradient), and the relative position of the self-vehicle image 34 between the line images 42 is changed to indicate the end of the coasting state. For example, as the coasting approaches a predetermined allowable speed, the distance between the line image 42 behind the self-vehicle image 34 and the self-vehicle image 34 is displayed to shorten. This allows the occupant to recognize that the vehicle is coasting due to the eco-driving cruise control. At this time, the change in the relative position of the self-vehicle image 34 between the line images 42 also allows the occupant to recognize the end of the coasting state.

[0054] In step 110, the CPU 16A determines whether or not the driver assistance has ended. This determination, for example, determines whether or not a command has been given to terminate the eco-driving cruise control function. If the determination is negative, the process returns to step 100 and the above processing is repeated. If the determination is positive, the process proceeds to step 112.

[0055] In step 112, CPU 16A hides icon 38 and status image, and terminates the series of processes.

[0056] As described above, the vehicle display device 12 according to this embodiment displays a status image that shows the acceleration state or coasting state by the advanced driver assistance ECU 22 when the eco-driving cruise control function is being executed, as well as an indication of when each state will end. This allows the occupant to know how far the vehicle will accelerate and how far it will coast, and to recognize not only whether or not driver assistance is being performed, but also the state of the driver assistance.

[0057] In the above embodiment, line images 42 are displayed as state images, with the line image 42 behind the vehicle image 34 being highlighted in the coasting state and the line image 42 in front of the vehicle image 34 being highlighted in the acceleration state. However, this is not the only configuration. For example, acceleration and coasting states may be represented solely by the change in the relative position of the vehicle image 34 between the line images 42, without any highlighting, and an indication of the end of each state may also be displayed.

[0058] Next, we will explain other examples of state images that represent the acceleration or coasting state of pulse-and-glide driving, as well as indicators of the end of each state.

[0059] As a state image, for example, a gauge image 44 representing an acceleration state or a coasting state may be displayed, as shown in Figures 7(A) and (B). Figures 7(A) and (B) show an example of displaying a gauge image as another example of a state image.

[0060] The gauge image 44 shows that the right side of Figures 7(A) and (B) indicates the end of coasting, and as shown in Figure 7(A), the gauge moves to the right as the vehicle approaches a predetermined allowable speed through coasting. This allows the occupant to recognize the coasting state and the indicator of the end of coasting from the gauge image 44. On the other hand, the left side of the gauge image 44 indicates the end of acceleration, and as shown in Figure 7(B), the gauge moves to the left as the vehicle approaches a predetermined speed through acceleration. This allows the occupant to recognize whether the vehicle is accelerating or coasting, and to recognize the indicator of the end of each state.

[0061] Furthermore, as state images, a vehicle image 34, a line image 42, and an arrow image 46 may be displayed, as shown in Figures 8(A) and (B). Figure 8(A) is a diagram showing an example of another state image, where a vehicle image, a line image, and an arrow image are displayed in a coasting state, and Figure 8(B) is a diagram showing an example of where a vehicle image, a line image, and an arrow image are displayed in an accelerating state.

[0062] The vehicle image 34 is displayed between the line images 42, and the arrow image 46 is displayed in front of or behind the vehicle image 34. As shown in Figure 8(A), displaying it behind indicates coasting, and as shown in Figure 8(B), displaying it in front indicates acceleration. Then, similar to the above embodiment, the relative position of the vehicle image 34 between the line images 42 is changed. Alternatively, the relative position of the arrow image 46 between the line images 42 is changed according to the state. This makes it possible to recognize whether the vehicle is accelerating or coasting, and to recognize an indication of the end of each state. Although an example has been described in which an indication of the end of each state is displayed by the relative position of the vehicle image 34 between the line images 42, or the relative position of the arrow image 46 between the line images 42, an indication of the end of each state may be displayed by other means. For example, the indication of the end may be displayed by changing the display mode of the arrow image. Specifically, the display mode of the arrow image 46, such as the color or flashing period, may be changed in several ways, and an indication of the end of each state may be displayed by changing the display mode such as the color or flashing period.

[0063] Furthermore, as a state image, as shown in Figures 9(A) and (B), a vehicle image 34, a line image 42, and an animation image 48 to the side of the vehicle image 34 may be displayed. Figure 9(A) is a diagram showing another example of a state image, displaying a vehicle image, a line image, and an animation image in a coasting state, and Figure 9(B) is a diagram showing an example of displaying a vehicle image, a line image, and an animation image in an acceleration state. Note that in Figure 9, the animation image 48 is shown displayed on both sides of the vehicle image 34, but it may also be displayed to the side of one side of the vehicle image 34.

[0064] The animated image 48 is displayed such that, for example, as shown in Figure 9(A), it moves forward of the vehicle image 34 when the vehicle is coasting. On the other hand, as shown in Figure 9(B), the animated image 48 moves backward of the vehicle image 34 when the vehicle is accelerating. The end of each state is indicated by changing the relative position of the vehicle image 34 between the line images 42, similar to the embodiment described above. This allows the user to recognize whether the vehicle is accelerating or coasting, and to recognize the end of each state. Although an example has been described in which the end of each state is indicated by the relative position of the vehicle image 34 between the line images 42, the end of each state may be indicated by other methods. For example, the end may be indicated by changing the display mode of the animated image. Specifically, the display mode of the animated image 48, such as its color or flashing cycle, may be changed in several ways, and the end of each state may be indicated by the change in the display mode, such as its color or flashing cycle.

[0065] Furthermore, although the state images in the above embodiment and the state images shown in Figures 5, 7 to 9 have been described as separate embodiments, the system is not limited to these. For example, the system may display a configuration in which at least two or more state images from the above embodiment and the state images shown in Figures 5, 7 to 9 are appropriately combined.

[0066] Furthermore, although the processing performed by the meter ECU 16 of the vehicle display device 12 in each of the above embodiments has been described as software processing performed by executing a program, it is not limited to this. For example, it may be processing performed by hardware such as a GPU (Graphics Processing Unit), ASIC (Application Specific Integrated Circuit), and FPGA (Field-Programmable Gate Array). Alternatively, it may be processing that combines both software and hardware. In the case of software processing, the program may be stored in various storage media and distributed.

[0067] Furthermore, the present invention is not limited to the above, and it is of course possible to implement it in various modified forms without departing from its spirit. [Explanation of Symbols]
