Description

The present invention relates to notification devices.

In recent years, vehicles are equipped with many sensing devices to detect a large amount of information in order to realize safe driving. Examples of sensing devices include radar, visible light cameras, ultrasonic detectors, and LiDAR (light detection and ranging). LiDAR can use light to detect the distance to objects around the vehicle.

Vehicles also use speakers, head-up displays (HUDs), and the like as devices for notifying the driver of the results of detection by these sensing devices.

JP 2016-184721 A

However, with the notification using the speaker, the driver may not be able to immediately recognize the voice when music is being played in the vehicle, or when there is lively conversation. Also, if the volume emitted by the speaker is too loud, the driver may be startled if the interior of the vehicle is quiet. Furthermore, in the notification using the HUD, the driver needs to read the contents displayed on the HUD, and there is a possibility that he/she cannot respond immediately. In addition, since the driver will immediately move his or her line of sight to the HUD, there is a possibility that the safety in the traveling direction will be insufficient.

Hereinafter, embodiments will be specifically described with reference to the accompanying drawings.

(First embodiment)
First, the first embodiment will be described. FIG. 1 is a diagram showing a notification device according to the first embodiment. FIG. 2 is a diagram showing the positional relationship between the windshield and the light emitter included in the notification device according to the first embodiment.

As shown in FIG. 1, the notification device 100 according to the first embodiment includes a windshield 110, a light emitter 120 that emits light from the edge 11 of the windshield 110, and a control device 130 that controls the operation of the light emitter 120. and have The light emitter 120 includes a plurality of types of light emitting diodes (LEDs) that emit light of different colors, and can emit light of a plurality of colors by combining the lit LEDs. For example, the windshield 110 is attached to the window frame of the vehicle and the light emitter 120 is positioned within the vehicle near the window frame. Windshield 110 is an example of a windowpane attached to a vehicle. Also, as the light emitter 120, a known light emitting member other than the above can be used, such as an organic EL (organic electroluminescence light emitting diode: OLED). In the description of the other embodiments, including the first embodiment, any of these light emitters 120 can be used unless otherwise specified.

The edge portion 11 is not particularly limited as long as it is the periphery of the windshield 110, but preferably within 10 cm from the end face, more preferably within 5 cm. Edge 11 is an example of a peripheral edge and is part of windshield 110 .

In a first embodiment, as shown in FIG. 2, a light emitter 120 is positioned on a dashboard 160 to illuminate the windshield 110 with light 121 . For example, the windshield 110 is made of laminated glass including an inner glass plate 112, an outer glass plate 113, and an intermediate film 116 sandwiched therebetween. A light-shielding film 114 and a reflective film 115 are sandwiched between the inner glass plate 112 and the outer glass plate 113 in the portion 11B. The light-shielding film 114 is located outside the vehicle relative to the reflective film 115 . As the light shielding film 114, for example, a black film or black ceramic can be used. Black ceramic can be formed by ceramic printing. A light blocking plate 161 is provided on the dashboard 160 to block the light emitter 120 from the driver's 190 view.

When the light emitter 120 emits light 121, part of this light 121 is reflected by the inner glass plate 112 and the other part is reflected by the reflective film 115, and the reflected light 122 is emitted into the vehicle. The configuration of the reflective film 115 can provide variation in the form of reflection. Further, even if part of the light 121 tries to travel toward the driver 190, it does not reach the driver 190 because the light blocking plate 161 is provided. Therefore, the light 121 emitted by the light emitter 120 can be suppressed from affecting the driver's 190 vision, and the light emitter 120 can emit strong light.

The driver 190 looks ahead through the windshield 110 while driving the vehicle, and even if the lower edge 11B emits light, the emitting lower edge 11B is out of sight of the driver 190. It does not obstruct the driver's 190 field of view and does not interfere with driving. In addition, since the driver 190 can feel intuitive information such as the color and mode (lighting, blinking, etc.) of the light emission of the lower edge 11B, the driver 190 can feel familiar with the color and mode of the light emission. Accordingly, the driver can intuitively recognize information to be sensed and its degree, specifically the degree of danger. For example, following the colors of traffic lights, the driver 190 can intuitively recognize that green indicates a safe situation, yellow indicates a cautionary situation, and red indicates an impending danger situation. Furthermore, since the light emission at the lower edge 11B does not allow the driver 190 to read letters, symbols or symbols like a head up display (HUD), the driver 190 can direct his/her line of sight to a specific position. You can easily grasp the situation without moving to

Even if part of the light 121 passes through the reflective film 115, it does not leak out of the vehicle because the light shielding film 114 is provided behind it. Therefore, it is possible to prevent oncoming vehicles and surrounding pedestrians from being dazzled.

Here, an example of notification by the notification device 100 will be described. 3 to 8 are diagrams showing examples of notifications on the windshield 110. FIG.

In the first example shown in FIG. 3, the positional relationship between the lane markings drawn on the road surface and the vehicle is notified. For example, the left part and the right part of the lower edge 11B emit white light. Specifically, when the vehicle is traveling on the right side of the lane, the right light emitting region 12R becomes narrower than the left light emitting region 12L as shown in FIG. When the vehicle is traveling on the left side, as shown in FIG. 3B, the right light emitting region 12R becomes wider than the left light emitting region 12L. Such light emission allows the driver 190 to intuitively recognize whether the vehicle is to the right or to the left.

It is preferable that the light emitting region 12R emits red light when the vehicle is extremely rightward, and the light emitting region 12L is red light when the vehicle is extremely leftward. This is for intuitively recognizing that the vehicle is crossing the lane.

In a second example, shown in FIG. 4, the lateral situation is notified. For example, when a following vehicle such as a car or a bicycle is running on the left rear or right rear, the light-emitting area of the lower edge 11B on the side where the following vehicle is running emits red light, and the following vehicle emits light. The light-emitting area on the side where the is not running emits green light. For example, when there is a following vehicle on the left and no following vehicle on the right, as shown in FIG. 4, the left emission region 12L emits red light and the right emission region 12R emits green light. Such light emission allows the driver 190 to intuitively recognize the approaching situation of the following vehicle.

As for the red light emission, it is preferable to vary the size of the light emitting region according to the approach speed of the following vehicle and the distance from the following vehicle. Specifically, it is preferable to widen the light-emitting region that emits red light as the approach speed of the following vehicle increases and the distance to the following vehicle decreases. In addition, yellow light may be emitted when there is a following vehicle that is approaching although the possibility of getting caught is low.

In a third example shown in FIG. 5, the situation ahead is notified. For example, as shown in FIG. 5, the entire lower edge portion 11B emits red light as the light emitting region 12F according to the speed difference and distance from the vehicle traveling ahead. Specifically, the smaller the speed difference and the longer the distance, the longer the red blinking interval, and the greater the speed difference and the shorter the distance, the shorter the red blinking interval. Such light emission allows the driver 190 to intuitively recognize the approaching situation of the vehicle ahead.

In a fourth example shown in FIG. 6, the operation status of an air conditioner, a defroster, or an electric heating device such as an ice-melting or anti-fogging device is notified. For example, in the case of notifying the operating status of an air conditioner, as shown in FIG. The lower edge 11B emits red light. Specifically, the light emitting region 12T spreads from the left end of the lower edge portion 11B, and as shown in FIG. 6A, the larger the temperature difference, the narrower the light emitting region 12T. As shown in (b), the light emitting region 12T reaches the right end. Such light emission allows the driver 190 to intuitively recognize the operation status of the air conditioner.

In a fifth example shown in FIG. 7, in a vehicle equipped with a driving assistance function, it is notified that the driving assistance function has been canceled. For example, as shown in FIG. 7, the entire lower edge portion 11B blinks in blue as the light emitting region 12A. Such light emission allows the driver 190 to intuitively recognize that the driving assist function has been canceled.

In the sixth example shown in FIG. 8, when the vehicle is moving backward, the distance to objects existing to the side and rear is notified. Also, the actual distance can be displayed visually. For example, the farther from the object, the narrower the light emission range, and the closer to the object, the wider the light emission range. Specifically, when there is an object such as a vehicle or a wall behind the right side and there is no object that may come into contact with the rear left side, as shown in FIG. It emits light that changes from green to yellow to red depending on the distance from. In addition, when there is an object that may come into contact with the entire rear portion, as shown in FIG. It emits light so that it changes to red over time.

Next, the control device 130 will be described. The control device 130 controls the operation of the light emitter 120 in accordance with signals from various sensing devices installed in the vehicle through processing described later, and realizes the light emission shown in FIGS. 3 to 8, for example. . Sensing devices include, for example, LiDAR, radar, visible cameras and ultrasonic detectors. For example, controller 130 is a semiconductor chip housed within dashboard 160 . FIG. 9 is a diagram showing the configuration of the control device 130. As shown in FIG.

The control device 130 includes a CPU (central processing unit) 131 , a ROM (read only memory) 132 , a RAM (random access memory) 133 and an auxiliary storage section 134 . The CPU 131, ROM 132, RAM 133 and auxiliary storage unit 134 constitute a so-called computer. Each part of the controller 130 is interconnected via a bus 135 .

The CPU 131 executes various programs (for example, a light emission control program) stored in the auxiliary storage section 134 .

ROM 132 is a non-volatile main memory device. The ROM 132 stores various programs and data necessary for the CPU 131 to execute various programs stored in the auxiliary storage unit 134 . Specifically, the ROM 132 stores a boot program such as BIOS (basic input/output system) and EFI (extensible firmware interface), data indicating the light emission pattern of the light emitter 120, and the like.

The RAM 133 is a volatile main storage device such as DRAM (dynamic random access memory) or SRAM (static random access memory). The RAM 133 functions as a work area that is developed when various programs stored in the auxiliary storage unit 134 are executed by the CPU 131 .

The auxiliary storage unit 134 is an auxiliary storage device that stores various programs executed by the CPU 131 and various data generated by the execution of the various programs by the CPU 131 .

The control device 130 has such a hardware configuration and performs the following processing. FIG. 10 is a flow chart showing details of processing by the control device 130 .

First, when a signal is input from the sensing device (step S1), the control device 130 identifies what kind of signal the signal is from which sensing device (step S2). Next, data indicating a light emission pattern corresponding to the specified signal is read out (step S3), and the light emitter 120 is controlled based on the data (step S4). For example, light emitter 120 is controlled such that any of the examples shown in FIGS. 3-8 are implemented.

According to the notification device 100 according to the first embodiment, the notification based on the detection result by the sensing device is performed based on the change in color, the change in the size of the light emitting area, and the like. Therefore, the driver 190 can intuitively recognize the content of the notification without reading characters, symbols, or the like. Also, the lower edge portion 11B of the windshield 110 is used for this notification. Since the line of sight of the driver 190 while driving is in front of the windshield 110, this notification instantly enters the field of view of the driver 190 within a range that does not interfere with driving. Furthermore, if it is a voice, there is a possibility that it will be affected by noise or the like, but by using light, it is possible to notify the driver 190 with an appropriate stimulus regardless of whether it is daytime or nighttime.

In the first embodiment, only the lower edge portion 11B of the edge portion of the windshield 110 emits light, but both sides and upper portion of the edge portion may emit light.

For example, in the first example, a right edge on the right side and a left edge on the left side may be used. That is, when the vehicle is traveling on the right side of the lane, as shown in FIG. 11A, the right edge portion 11R emits light narrower than the left edge portion 11L, and the vehicle runs on the left side of the lane. 11B, the right edge 11R may emit light wider than the left edge 11L. Also in this case, it is preferable that the right edge portion 11R emits red light when the vehicle is extremely rightward, and the light emitting region 12L emits red light when the vehicle is extremely leftward.

Also, for example, in the second example, a right edge and a left edge may be used. That is, when there is a following vehicle on the left and there is no following vehicle on the right, the left edge 11L may emit red light and the right edge 11R may emit green light, as shown in FIG. In this case as well, it is preferable to widen the red light emitting region as the approach speed of the following vehicle increases and as the distance to the following vehicle decreases.

Further, for example, in the third example, right and left edges may be used. That is, as shown in FIG. 13, not only the lower edge portion 11B but also the right edge portion 11R and the left edge portion 11L may emit red light depending on the speed difference and distance from the vehicle traveling ahead.

Also, for example, in the sixth example, the right and left edges may be used during rearward movement of the vehicle. That is, when there is an object on the right rear and no object on the left rear that may come into contact with the object, as shown in FIG. The light may be emitted so as to change to red through . Moreover, when there is an object that may come into contact with the entire rear area, as shown in FIG. It may emit light that changes from green to yellow to red accordingly. Illumination of the right edge 11R and left edge 11L is particularly preferred because the driver 190 looks to the rear of the vehicle rather than to the front of the windshield 110 when moving backwards. Further, similar light emission may be performed not only at the windshield 110 but also at the edge of the rear window.

(Second embodiment)

For example, the windshield 110 includes an inner glass plate 112, an outer glass plate 113, and an intermediate film 116, and a laminated glass that does not include the light shielding film 114 and the reflective film 115 is used. A light shielding film 214 is provided on the surface of . As the light shielding film 214, for example, a black film or black ceramic can be used. A black film or black ceramic containing a component that enhances reflection to the inside of the vehicle may also be used. Other configurations are the same as those of the first embodiment.

It is preferable that the light shielding film 114 be positioned outside the vehicle relative to the light emitter 120 . A diffusion film 315 is preferably provided on the surface of the inner glass plate 112 . In the fourth embodiment, there is no need to provide the light emitter 120 and the light shielding plate 161 on the dashboard 160 . Furthermore, other configurations are similar to those of the first embodiment.

The same effect as the notification device 100 can be obtained by the notification device 400 configured in this manner. Moreover, according to the notification device 400, since the light emitter 120 and the light blocking plate 161 on the dashboard 160 are not required, the configuration on the dashboard 160 can be simplified as compared with the first embodiment. Further, similarly to the third embodiment, by providing the diffusion film 315, the light 322 with high intensity uniformity can be emitted, and the light stimulus received by the driver 190 can be alleviated.

As the light emitter 120 sandwiched between the inner glass plate 112 and the outer glass plate 113, LEDs and OLEDs can be suitably used.
