Abstract
Description
Technical Field
[0001] This invention relates to an information processing device. Background Technology
[0002] Patent document 1 discloses a technology that can suppress the confusion between road markings or lines and the projected image, even when projecting an image behind the vehicle during a reversing motion.
[0003] Patent Document 1: Japanese Patent Application Publication No. 2024-022275 Summary of the Invention
[0004] When a vehicle is reversing, in addition to using the reversing lights to notify pedestrians and other pedestrians in the surrounding area, it is preferable to also notify the reversing speed as a way of showing consideration for the surroundings. However, in the technology described in Patent Document 1, there is no disclosure regarding notifying the surroundings of the reversing speed when reversing, and there is room for improvement in the content of the notification to the surroundings when reversing.
[0005] Therefore, the object of the present invention is to provide an information processing device that can notify the surrounding reversing speed based on the content drawn on the road surface at the reversing destination of the vehicle.
[0006] Technical solution 1 relates to an information processing device comprising: an acquisition unit that acquires vehicle information including information indicating the shift position and speed of a vehicle; and a control unit that, when the shift position indicated by the vehicle information acquired by the acquisition unit is reverse gear (R), controls a drawing device capable of drawing a notification display on the road surface at the destination of the vehicle's reversing direction using light, so that the notification display is displayed on the road surface in a manner corresponding to the vehicle speed indicated by the vehicle information.
[0007] In the information processing apparatus of technical solution 1, the acquisition unit acquires vehicle information including information indicating the vehicle's shift position and speed. Furthermore, when the shift position indicated by the vehicle information acquired by the acquisition unit is reverse gear (R), the control unit controls the drawing device to display a notification on the road surface in a manner corresponding to the vehicle speed indicated by the vehicle information. Therefore, according to this information processing apparatus, it is possible to notify the surrounding area of the reversing speed based on the content drawn on the road surface at the vehicle's reversing destination.
[0008] Regarding the information processing device involved in technical solution 2, in technical solution 1, when the control unit is in the first state where the shift position is R gear and the vehicle speed is 0, the notification display, in a manner corresponding to the first state, causes a first notification display in a pre-set shape to be continuously drawn by light and displayed on the road surface.
[0009] In the information processing device according to technical solution 2, when the control unit is in the first state (shifting to reverse gear and the vehicle speed is 0), a first notification display, which is a pre-set shape of light continuously drawn, is displayed on the road surface. Therefore, according to this information processing device, the vehicle can be notified to those around it that it is stationary based on the first notification display.
[0010] Regarding the information processing device involved in technical solution 3, in technical solution 2, when the control unit is in the second state where the shift position is R gear and the vehicle speed exceeds 0 and is below a threshold, the notification display, in a manner corresponding to the second state, displays a second notification on the road surface by switching the shape of light every first time interval.
[0011] In the information processing device involved in technical solution 3, when the control unit is in the second state (shifting to reverse gear, vehicle speed exceeding 0 but below a threshold), it displays a second notification on the road surface, showing a light pattern that switches and is drawn every first time interval. Thus, according to this information processing device, it is possible to notify the surrounding area that the vehicle is reversing at a speed below the threshold based on the second notification display.
[0012] Regarding the information processing device involved in technical solution 4, in technical solution 3, when the control unit is in the third state where the shift position is R gear and the vehicle speed exceeds the threshold, the notification display, in a manner corresponding to the third state, displays a third notification on the road surface by switching the shape of light every second time interval, wherein the second time interval is shorter than the first time interval.
[0013] In the information processing device of technical solution 4, when the control unit is in the reverse gear (R) and the vehicle speed exceeds a threshold (a third state), it displays a third notification on the road surface, where the shape of the light changes and is drawn every second time interval, and the second time interval is shorter than the first time interval. Therefore, according to this information processing device, it is possible to notify the surrounding area that the vehicle is reversing at a speed exceeding the threshold based on the third notification display.
[0014] Regarding the information processing device involved in technical solution 5, in technical solution 4, when the control unit is in the first state, the second state, or the third state, it makes at least one of the brightness and color of the light drawn on the road surface by the drawing device different.
[0015] In the information processing device according to technical solution 5, the control unit, in the first, second, or third state, causes at least one of the brightness and color of the light drawn on the road surface by the drawing device to be different. Therefore, according to this information processing device, it is possible to notify the surrounding area whether the vehicle is not reversing or is reversing based on at least one of the brightness and color of the light drawn on the road surface at the vehicle's reversing destination.

[0024] The vehicle 10 described below is an example of this embodiment.
[0025] Figure 1 This is a block diagram representing the hardware structure of vehicle 10. For example... Figure 1 As shown, vehicle 10 includes an Electronic Control Unit (ECU) 20 for lighting. Vehicle 10 is an example of a "vehicle" according to the present invention, and the lighting ECU 20 is an example of an "information processing device" according to the present invention.
[0026] The lighting ECU 20 comprises a Central Processing Unit (CPU) 21, a Read Only Memory (ROM) 22, a Random Access Memory (RAM) 23, a storage device 24, an in-vehicle communication interface (I / F) 25, an input / output interface (I / F) 26, and a wireless communication interface (I / F) 27. The CPU 21, ROM 22, RAM 23, storage device 24, in-vehicle communication interface (I / F) 25, input / output interface (I / F) 26, and wireless communication interface (I / F) 27 are communicatively connected via an internal bus 28.
[0027] CPU 21 is the central processing unit, which executes various programs or controls various parts. That is, CPU 21 reads programs from ROM 22 or storage device 24 and uses RAM 23 as its working area to execute the programs. CPU 21 performs control and various arithmetic operations on the above-mentioned structures according to the programs recorded in ROM 22 or storage device 24.
[0028] ROM22 stores various programs and data. RAM23 serves as the working area to temporarily store programs or data.
[0029] Storage device 24 is composed of storage devices such as embedded Multi Media Card (eMMC) or Universal Flash Storage (UFS), and stores various programs and data. Information processing program 24A is stored in storage device 24. Information processing program 24A is used to cause CPU 21 to perform specific processes described later (see reference). Figure 2 The program.
[0030] The in-vehicle communication I / F25 is an interface for connecting with other ECUs 30. This interface uses a CAN-based communication standard. The in-vehicle communication I / F25 connects to the external bus 29. Additionally, although not shown in the diagram, multiple ECUs are provided for each function of the vehicle 10, besides ECU 30.
[0031] Input / output I / F26 is an interface for communicating with the drawing device 40 mounted on the vehicle 10. The drawing device 40 is an example of the "drawing device" of the present invention.
[0032] The drawing device 40 is capable of using light to draw a notification display 50 on the road surface at the destination of the vehicle 10's reversal (reference). Figure 3The drawing device 40 includes a light source 42 and a light deflection device 44, which draws a notice display 50 on the road surface by illuminating the road surface with light from the light source 42. The drawing device 40 can change the brightness, color, shape, illumination position, and illumination range of the illuminated light.
[0033] As a light source 42, for example, semiconductor light-emitting elements such as light-emitting diodes (LEDs), laser diodes (LDs), electroluminescence (ELs), light bulbs, halogen lamps, or incandescent lamps can be used.
[0034] The light deflection device 44 directs light from the light source 42 to the outside. For example, a digital micromirror device (DMD) or a digital mirror device (DLP) can be used as the light deflection device 44. For instance, the light deflection device 44 has a micromirror array composed of a matrix of multiple tiny mirror elements having reflective surfaces on their surfaces. By controlling the opening and closing of each mirror element arranged in the matrix, various light distribution patterns can be formed within the micromirror array.
[0035] As the light source 42, three or more light source units, such as red, green, and blue, can be used to illuminate the light deflection device 44 in a time-division manner, switching the mirror element on and off to achieve the desired color of light. Furthermore, a notification display 50 with the desired brightness and color and a desired shape formed by a matrix of emitted light can be drawn onto the road surface.
[0036] Alternatively, the optical deflection device 44 can be replaced by a microelectromechanical system (MEMS) or a multi-faceted mirror.
[0037] The drawing device 40 is configured to oscillate via a motor, etc. Rear combination lamp 46 (reference) Figure 3 The drawing device 40 (etc.) is controlled by the control unit 21B described later, and can tilt up, down, left, and right to switch the direction of light illuminating the road surface to the rear or diagonally rear of the vehicle 10.
[0038] The I / F27 wireless communication module is used for communicating with external devices. This wireless communication module uses communication standards such as 5G, LTE, Wi-Fi (registered trademark), and Bluetooth (registered trademark).
[0039] Furthermore, the CPU 21 of the lighting ECU 20 has an acquisition unit 21A and a control unit 21B as its functional structure. Each functional structure is implemented by the CPU 21 reading and executing the information processing program 24A stored in the storage device 24.
[0040] The acquisition unit 21A acquires various types of information. For example, the acquisition unit 21A acquires vehicle information related to the state of the vehicle 10 from the ECU 30 as various types of information. The vehicle information includes information indicating the shift position, vehicle speed, throttle opening, and brake pedal pressure of the vehicle 10. The ECU 30 outputs vehicle information as the throttle opening detected by the throttle position sensor (not shown), the brake pedal pressure detected by the brake position sensor (not shown), the shift position detected by the shift sensor (not shown), and the vehicle speed detected by the vehicle speed sensor (not shown) to the lighting ECU 20.
[0041] The control unit 21B controls the drawing device 40 to display a notification display 50 on the road surface at the destination of the vehicle 10's reversal. Specifically, when the control unit 21B detects that the gear shift position is R based on the vehicle information acquired by the acquisition unit 21A, it controls the drawing device 40 to display a notification display 50 on the road surface in a manner corresponding to the vehicle speed.
[0042] Figure 2 This is a flowchart illustrating the specific processing performed by the lighting ECU 20. The CPU 21 reads the information processing program 24A from the storage device 24, expands it into the RAM 23, and executes it, thereby performing specific processing. As an example, the specific processing is performed automatically and repeatedly after a certain period of time.
[0043] exist Figure 2 In step S10, CPU 21 obtains vehicle information from ECU 30. Then, CPU 21 proceeds to step S11.
[0044] In step S11, CPU 21 determines whether the shift position is R (reverse) based on the vehicle information obtained in step S10. If CPU 21 determines that the shift position is R (step S11: Yes), it proceeds to step S12. Conversely, if CPU 21 determines that the shift position is not R (step S11: No), it terminates the specific processing.
[0045] In step S12, CPU 21 determines whether vehicle 10 is in a braking state based on the vehicle information obtained in step S10. A braking state is defined as the brake pedal being depressed and the vehicle speed being 0. This braking state is an example of the "first state" of the present invention. Here, if CPU 21 determines that the vehicle is in a braking state (step S12: Yes), it proceeds to step S13. Conversely, if CPU 21 determines that the vehicle is not in a braking state (step S12: No), it proceeds to step S14.
[0046] In step S13, CPU 21 controls the drawing device 40 to display a notification display 50 corresponding to the braking state on the road surface. Then, CPU 21 terminates the specific processing.
[0047] In step S14, CPU 21 determines whether vehicle 10 is in a creeping state based on the vehicle information obtained in step S10. A creeping state is a state where the brake pedal is not depressed and the vehicle speed exceeds 0 but is below a threshold. That is, a creeping state is a state where vehicle 10 is moving slowly in a creeping phenomenon. The creeping state is an example of the "second state" of the present invention. Here, if CPU 21 determines that it is in a creeping state (step S14: Yes), it proceeds to step S15. On the other hand, if CPU 21 determines that it is not in a creeping state (step S14: No), it proceeds to step S16.
[0048] In step S15, CPU 21 controls the drawing device 40 to display a notification display 50 on the road surface in a manner corresponding to the creeping state. Then, CPU 21 terminates the specific processing.
[0049] In step S16, CPU 21 determines whether vehicle 10 is in throttle mode based on the vehicle information obtained in step S10. Throttle mode is a state where the accelerator pedal is depressed and the vehicle speed exceeds the aforementioned threshold. Throttle mode transitions from creep mode by depressing the accelerator pedal. Throttle mode is an example of the "third state" of the present invention. Here, if CPU 21 determines that it is in throttle mode (step S16: Yes), it proceeds to step S17. On the other hand, if CPU 21 determines that it is not in throttle mode (step S16: No), it terminates the specific process.
[0050] In step S17, CPU 21 controls drawing device 40 to display notification display 50 on the road surface in a manner corresponding to the throttle state. Then, CPU 21 terminates the specific processing.
[0051] Next, use Figures 3-5 The drawing content on the road surface of the vehicle 10's reverse destination, drawn by the drawing device 40, will be explained.
[0052] Figure 3This is the first explanatory diagram showing the road surface depicting the destination of vehicle 10's reversal. The following is an explanation of... Figure 3 In the following descriptions, this road surface will be referred to as "Road Surface R". Furthermore, in Figure 3 In the following diagrams, the shift position of vehicle 10 is set to R gear.
[0053] exist Figure 3 The image shows the rear of the vehicle 10, including the rear combination lights 46, and the road surface R.
[0054] Here, Figure 3 This describes the drawing of the road surface R when the vehicle 10 is in a braking state. In this case, the CPU 21 controls the drawing device 40 to display a first notification display 52, which is a notification display 50 corresponding to the braking state, and continuously draws light of a preset shape on the road surface R. In this embodiment, as an example, the preset shape is set to rectangle, but the shape is not particularly limited. As an example, the first notification display 52 consists of three rectangular lights, namely lights 52A, 52B, and 52C, drawn diagonally to the left rear of the vehicle 10, and three rectangular lights, namely lights 52D, 52E, and 52F, drawn diagonally to the right rear of the vehicle 10. The first notification display 52 remains displayed on the road surface R until the vehicle 10 is no longer in a braking state. In contrast, if the vehicle 10 changes from a braking state to a creeping state or an accelerator state, the CPU 21 switches the notification display 50 from the first notification display 52 to the second notification display 54 or the third notification display 56, which will be described later, according to the state of the vehicle 10.
[0055] Figure 4 This is the second explanatory diagram showing the drawing content of the road surface R.
[0056] Here, Figure 4 This indicates the first drawing of the road surface R when the vehicle 10 is in a creeping state. In this case, the CPU 21 controls the drawing device 40 to display a second notification display 54 on the road surface R, which is a notification display 50 corresponding to the creeping state and whose light shape is switched and drawn every X seconds. X seconds is an example of the "first time" of this invention.
[0057] As an example, the second notification shows 54 in Figure 4 In the initial state shown on the left, it consists of a rectangular light beam 54A drawn towards the left rear of vehicle 10 and a rectangular light beam 54D drawn towards the right rear of vehicle 10. After X seconds from this initial state... Figure 4In the intermediate state shown in the central part, the second notification display 54 consists of two rectangular lights, namely lights 54A and 54B, drawn diagonally to the left rear of vehicle 10, and two rectangular lights, namely lights 54D and 54E, drawn diagonally to the right rear of vehicle 10. After X seconds from this intermediate state... Figure 4 In the final state shown in the right part, the second notification display 54 consists of three rectangular lights, namely lights 54A, 54B, and 54C, drawn diagonally to the left rear of vehicle 10, and three rectangular lights, namely lights 54D, 54E, and 54F, drawn diagonally to the right rear of vehicle 10. Thus, the second notification display 54 draws the lights sequentially, gradually moving away from the vicinity of vehicle 10. Furthermore, the second notification display 54 transitions to the initial state after X seconds from the final state.
[0058] Figure 5 This is the third explanatory diagram showing the drawing content of the road surface R.
[0059] Here, Figure 5 This indicates the content of the road surface R when the vehicle 10 is in the accelerator position. In this case, the CPU 21 controls the drawing device 40 to display a third notification display 56 on the road surface R, which is a notification display 50 corresponding to the accelerator position and whose light shape is switched and drawn every Y seconds shorter than X seconds. Y seconds is an example of the "second time" of the present invention.
[0060] As an example, the third notification shows 56 in Figure 5 In the initial state shown on the left, it consists of a rectangular light beam 56A drawn towards the left rear of vehicle 10 and a rectangular light beam 56D drawn towards the right rear of vehicle 10. After Y seconds from this initial state... Figure 5 In the intermediate state shown in the central part, the third notification display 56 consists of two rectangular lights, namely lights 56A and 56B, drawn diagonally to the left rear of vehicle 10, and two rectangular lights, namely lights 56D and 56E, drawn diagonally to the right rear of vehicle 10. After Y seconds from this intermediate state... Figure 5 In the final state shown in the right part, the third notification display 56 consists of three rectangular lights, namely lights 56A, 56B, and 56C, drawn diagonally to the left rear of vehicle 10, and three rectangular lights, namely lights 56D, 56E, and 56F, drawn diagonally to the right rear of vehicle 10. Thus, the third notification display 56 draws the lights sequentially, gradually moving away from the vicinity of vehicle 10. Furthermore, the third notification display 56 transitions to the initial state after Y seconds from the final state.
[0061] As explained above, in the lighting ECU 20, the CPU 21 acquires vehicle information including information indicating the shift position and speed of the vehicle 10. Furthermore, when the shift position indicated by the acquired vehicle information is reverse (R), the CPU 21 controls the drawing device 40 to display a notification display 50 on the road surface R, corresponding to the vehicle speed indicated by the vehicle information. Therefore, according to this lighting ECU 20, it is possible to notify the surrounding area of the reverse speed based on the drawing content of the road surface R.
[0062] Furthermore, in the lighting ECU 20, when the CPU 21 is in reverse gear (R) and the vehicle speed is 0, it displays a first notification display 52, which continuously draws a pre-set shape of light, on the road surface R. Thus, according to this lighting ECU 20, the vehicle 10 can be notified to stop by the surrounding area based on the first notification display 52.
[0063] Furthermore, in the lighting ECU 20, when the CPU 21 is in reverse gear (R) and the vehicle speed is above 0 but below a threshold (creep mode), a second notification display 54, which changes the shape of the light every X seconds, is displayed on the road surface R. Thus, according to this lighting ECU 20, the second notification display 54 can notify surrounding vehicles 10 to reverse at a speed below the threshold.
[0064] Furthermore, in the lighting ECU 20, when the CPU 21 is in reverse gear (R) and the vehicle speed exceeds a threshold, it displays a third notification display 56 on the road surface (R) by switching the shape of the light every Y seconds shorter than X seconds. Thus, according to this lighting ECU 20, the third notification display 56 can notify surrounding vehicles 10 to reverse at speeds exceeding the threshold.
[0065] Furthermore, in the lighting ECU 20, the CPU 21 adjusts the brightness and color of the light drawn on the road surface R by the drawing device 40 to be different depending on whether the vehicle is braking, creeping, or throttled. Therefore, according to this lighting ECU 20, the vehicle 10 can be notified to the surrounding area whether it is reversing or not based on the brightness and color of the light drawn on the road surface R.
[0066] (other)
[0067] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the technical scope of the present invention is not limited to these examples. Those skilled in the art will obviously be able to conceive of various modifications or alterations within the scope of the technical concept described in the claims, and such modifications or alterations are naturally understood to fall within the technical scope of the present invention.
[0068] Furthermore, the effects described in the above embodiments are illustrative or exemplary and are not limited to the effects described in the above embodiments. That is, the technology involved in this invention can achieve other effects besides those described in the above embodiments, or replace the effects described in the above embodiments, that are obvious to those skilled in the art from the descriptions in the above embodiments.
[0069] The processing described in the above embodiments can also be implemented using dedicated hardware circuitry. In this case, it can be executed by one piece of hardware or by multiple pieces of hardware.
[0070] In the above embodiment, the information processing program 24A is stored in the storage device 24. However, it is not limited to this, and the information processing program 24A may also be stored in the ROM 22.
[0071] In the above embodiments, the content of the second notification display 54 and the third notification display 56, which switch the shape of the light at predetermined intervals, is not limited to the above content. For example, the content can be flashing by switching the light on and off in a pre-set shape at predetermined intervals.
[0072] Figure 6 This is the fourth explanatory diagram showing the drawing content of the road surface R.
[0073] Here, Figure 6 This indicates the second drawing of the road surface R when the vehicle 10 is in a creeping state. In this case, the CPU 21 controls the drawing device 40 to display a second notification display 54 on the road surface R, which is a notification display 50 corresponding to the creeping state and flashes with a pre-set shape of light turning on and off every Z seconds. Z seconds is an example of the "first time" of the present invention.
[0074] As an example, the second notification shows 54 in Figure 6 The illuminated state shown on the left is composed of three rectangular lights (lights 54A, 54B, and 54C) drawn diagonally to the left rear of vehicle 10, and three rectangular lights (lights 54D, 54E, and 54F) drawn diagonally to the right rear of vehicle 10. After Z seconds from this illuminated state... Figure 6 In the off state shown in the central part, notification 2 indicates that all the aforementioned lights are extinguished. After Z seconds from this off state... Figure 6 In the lit state shown in the right part, the second notification display 54 illuminates all the aforementioned lights again. Thus, the second notification display 54 switches the lighting and extinguishing of lights 54A, 54B, 54C, 54D, 54E, and 54F every Z seconds.
[0075] Furthermore, the above explanation uses the example of notification number 54 shown in the second notification, but... Figure 6 The structure shown can also be applied to the third notification display 56. In this case, the switching time between the light on and off of the third notification display 56 is shorter than Z seconds for the second notification display 54.
[0076] In the above embodiments, the CPU 21, when in braking, creeping, or throttle mode, causes the brightness and color of the light drawn by the drawing device 40 onto the road surface R to differ, but is not limited to these states. In each of these states, the CPU 21 may only change the brightness or only change the color of the light drawn by the drawing device 40 onto the road surface R. Furthermore, in each of these states, the CPU 21 may only change at least one of the shape and illumination range of the light drawn by the drawing device 40 onto the road surface R.
[0077] For example, the illumination range of the light drawn by the drawing device 40 onto the road surface R when the CPU 21 is in throttle mode can be wider than the illumination range of the light drawn by the drawing device 40 onto the road surface R when in creep mode. Therefore, it is possible to provide advance notice of a throttle state that allows for reversing at a speed faster than in creep mode to a wider range of vehicles.
[0078] In the above embodiment, the CPU 21 switches and draws the shape and illumination range of the light at predetermined intervals when in creep mode or throttle mode, but is not limited to this. For example, when in creep mode or throttle mode, the CPU 21 can switch and draw the illumination position (illumination direction) of the light at predetermined intervals. Specifically, when in creep mode or throttle mode, the CPU 21 can control the drawing device 40 so that in the initial state, light is illuminating the oblique rear of the vehicle 10, in the intermediate state, light is illuminating the rear of the vehicle 10, and in the final state, light is illuminating the oblique rear of the vehicle 10.
[0079] In the above embodiment, the drawing device 40 is provided to be included in the rear combination light 46 and draw the notification display 50 on the road surface of the vehicle 10's reverse destination. However, in addition, the drawing device 40 may also be provided to be included in the headlight and draw the notification display 50 on the road surface of the vehicle 10's forward destination.
[0080] In the above embodiment, the lighting ECU20 executes... Figure 2 The specific processing is shown. However, it is not limited to this; the specific processing can also be performed by the lighting ECU20 in cooperation with other ECUs.
[0081] Alternatively, various processors other than the CPU can execute the specific processing of the software (program) read and executed by the CPU 21 in the above embodiment. Examples of processors in this case include programmable logic devices (PLDs) whose circuit structure can be modified after manufacturing, such as field-programmable gate arrays (FPGAs), and application-specific integrated circuits (ASICs), which have circuit structures specifically designed for executing specific processing—i.e., dedicated circuits. Furthermore, the specific processing can be executed by one of these various processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs or a combination of a CPU and an FPGA). More specifically, the hardware structure of these various processors is a circuit composed of combined semiconductor elements and other circuit elements.
[0082] Furthermore, while the above embodiment describes the information processing program 24A being pre-stored (installed) in the storage device 24, it is not a limitation. The information processing program 24A may also be provided on a recording medium such as a compact disk read-only memory (CD-ROM), a digital versatile disk read-only memory (DVD-ROM), or a universal serial bus (USB) memory. Additionally, the information processing program 24A may be downloaded from an external device via a network. Moreover, the technology of this invention can also be applied to programs and program products.
