Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle position confirmation device that is installed in a vehicle and is used to confirm the approach distance between the vehicle and another object.

[Prior Art] When approaching a fence or a parked vehicle while backing up, it takes a high level of skill to accurately grasp the approach distance between these objects and the rear end of the side of the vehicle. It takes.

In particular, in car body designs where the rear side of the car body is largely narrowed down, or in car body designs called high decks where the luggage door is placed in a high position, it is difficult to visually check the rear corners of the car body sides, so it is difficult to visually check the rear corners of the car body. I have no choice but to rely on it.

In addition, in a vehicle equipped with a four-wheel steering system where the rear wheels are steered in opposite phases, when starting from parallel parking, etc., the rear of the vehicle is pushed in the opposite direction to the steering direction of the front wheels, approaching a fence or other vehicle. do. In this case, since the vehicle is moving forward, it is necessary to check the front, so it is not possible to look back and check the approaching state of the rear of the vehicle, so it is necessary to check only from the side mirrors such as door mirrors or fender mirrors. However, it is much more difficult to determine the exact distance when checking through the side mirrors than when checking directly visually.

[Problems to be solved by the invention] Taking the above facts into consideration, the present invention makes it possible to easily grasp the approach distance to other objects at the rear of the vehicle body, particularly on the sides of the rear rear of the vehicle, and to easily determine the relative distance to other objects. It is an object of the present invention to provide a vehicle position confirmation device that can easily grasp the angle.

[Means and effects for solving the problem] The present invention is a position confirmation device installed in a vehicle to confirm the approach distance between the vehicle and another object, and the device is arranged along the front and rear direction of the vehicle. first to third light emitting parts, and first to third light emitting parts arranged below the first to third light emitting parts and corresponding to the first to third light emitting parts along the longitudinal direction of the vehicle. 4th to 6th light emitting parts, and among the light emitting parts,

The irradiation optical axes of the third and sixth light emitting parts, which are inclined toward the rear of the vehicle at a predetermined angle with respect to the irradiation optical axes of the light emitting parts, are the same in plan view. and the other object The object is characterized in that the other object is irradiated so that the irradiation pattern of the first to sixth light emitting parts on the other object changes in response to a change in the approach distance to the other object.

With this configuration, changes in the distance between the vehicle and other objects can be determined from changes in the irradiation pattern.

[Embodiment] FIG. 5 shows a vehicle 10 equipped with a vehicle position confirmation device according to the present invention. The vehicle 10
Door mirrors 114 are attached to the left and right front doors 12, respectively.

A light emitting device 20 is fitted into a recess formed in a bumper molding 17 of the rear bumper 16 at the left and right corners 18 of the rear bumper 16 of the vehicle 10, respectively.

As shown in FIGS. 1 to 3, the light emitting device 20 includes a strobe discharge tube 22A as a light source body 22,
22B, 22C, each discharge tube 22A, 22
The discharge tubes B and 22C are arranged in a line in the longitudinal direction of the vehicle, with the discharge tube 22C located at the frontmost position, and are housed in independent small rooms. Each discharge tube 22A, 22B,
Lenses 24A and 24 serving as first to third light emitting portions are provided upwardly on the vehicle outer side of 22C, respectively.
B, 24C are arranged, and lenses 24D, 24E, 24F, which serve as fourth to sixth light emitting parts, are arranged below.

The optical axes of the lenses 24B and 24E are perpendicular to the center line passing in the longitudinal direction of the vehicle when viewed from above the vehicle, and the optical axes of the lenses 24A and 24D are perpendicular to the center line passing through the longitudinal direction of the vehicle.
The optical axes of lenses 24C and 24F are inclined at an angle θ1 toward the rear of the vehicle with respect to the optical axes of lenses 24B and 22.
It is inclined at an angle θ1 toward the front of the vehicle with respect to the optical axis of E. Further, the optical axes of the lenses 24A, 24B, and 24C are inclined upward when viewed from the light source 22, and the optical axes of the lenses 24D, 24E, and 24F are
The included angle between the optical axes of the upper lenses 24A, 24B, and 24C and the optical axes of the lower lenses 24D, 24E, and 24F is an angle θ. In this embodiment, the angle θ is set to 54°.

The light emitting device 20 is disposed on the outer side of the vehicle body of each lens and is covered with a light-transmissive lens cover 26 that is substantially flush with the bumper molding 17.

Here, the strobe discharge tubes 22A, 22B,
When the strobe discharge tube 22C emits light by discharge, the strobe discharge tube 22A is connected to the lenses 24A and 24D as shown in FIG.
The strobe discharge tube 22B emits a circular upward main beam 28B and a circular downward main beam 28E through lenses 24B and 24E. The tube 22C is the lens 24
C, 24F, an oblong upward sub-beam 28A and a downward sub-beam 28D extending in the horizontal direction are emitted, respectively.

Next, the operation of this embodiment will be explained.

Now, when the vehicle 10 is moved backward so as to approach the fence 32 at a place where the fence 32 exists on the rear side of the vehicle 10, the strobe discharge tubes 22A, 22B, and 22C of the light emitting device 20 are discharged. It emits light. This light emission is started, for example, by turning on a manual switch provided in the vehicle interior. Alternatively, this can be done by a switch linked to the reverse position of the transmission. When the strobe discharge tubes 22A, 22B, 22C discharge and emit light, six beams 28A, 2 are emitted as shown in FIG.
8B, 28C, 28D, 28E, and 28F are irradiated onto the wall 32 in the irradiation pattern described above, and the irradiation pattern of these beams is clearly visible through the right side door mirror 14 (not shown).

Here, since the vertical line E connecting the upward main beam 28B and the downward main beam 28E indicates the position of the rear end of the side of the vehicle, the rear of the side of the vehicle is large as shown in FIG. Even if the rear corner cannot be seen from the driver's seat due to the narrowed-down position, the occupant can reliably grasp the position of the rear end of the vehicle side surface in relation to the wall 32.

Further, since the upward beams 28A, 28B, 28C and the downward beams 28D, 28E, 28F are provided with an angle θ, the upward beams 28A, 28B, 28C,
The longer the distance T (see FIG. 5) between 28C and the downward beams 28D, 28E, and 28F, the farther the vehicle 10 is from the wall 32. On the contrary, fence 32
If the car 10 approaches , the interval T becomes shorter. fence 3
If the second-class object is vertical, the distance between the vehicle 10 and the object will be approximately the same as the distance T.

Therefore, the occupants can use the upward beams 28A, 28B, 2
8C and the length of the interval T between the downward beams 28D, 28E, and 28F, even if it cannot be seen directly, the vehicle 10
The approaching distance between the rear end portion and the fence 32 can be grasped, and appropriate driving operations can be performed according to the approaching distance.

In this embodiment, the light emitting device 20 is configured to emit a plurality of beams (six beams) simultaneously in the horizontal direction and the vertical direction, but even if only the upward main beam 28B and the downward main beam 28E are emitted, Effects can be obtained.

However, by emitting the beams as in the above embodiment, the main beams 28B and 28E form a unique irradiation pattern sandwiched between the sub-beams 28A, 28C, 28D, and 28F, making it easy to mistake them for other light beams. In addition, when the main beams 28B and 28E are not clearly visible, the sub beams 28A and 28
It becomes possible to effectively use C, 28D, and 28F in an auxiliary manner. For example, as shown in FIG. 7, the sub-beams 28A and 28D are
If the object cannot be seen, it can be determined that the own vehicle and another object (the other vehicle in the figure) are not parallel, and the rear end of the vehicle in the state reflected in the main beams 28B, 28E and the door mirror 14. The intersection angle with other objects can be determined from the separation distance from the object.

Further, in the above embodiment, the approach distance is determined by the distance between the beams in the vertical direction, but it is also possible to determine the approach distance by the distance between the beams in the horizontal direction.

Furthermore, if the beam irradiation pattern changes as it moves away from the light emitting device 20, it is also possible to determine the approach distance using only a single beam.

In this embodiment, a strobe discharge tube was used as the light source, but a tungsten bulb or the like may also be used.

FIG. 4 shows a modification of this embodiment,
In this embodiment, main beams 28B, 28E (2
8E (not shown)) is different from the previous embodiment in that the light emitting device 20 is arranged so that the optical axis of the light emitting device 20 is inclined toward the rear of the vehicle with respect to a line perpendicular to the center line along the longitudinal direction of the vehicle. ing.

This is because the shape of the rear bumper 16 is an arc whose longitudinal center portion extends toward the rear of the vehicle, and the distance between the installation position of the light emitting device 20 and the rearmost end of the vehicle in the longitudinal direction of the vehicle is relatively large. Although it is not possible to accurately determine the rear end of the vehicle, it can limit the general range of use.

[Effects of the invention] As explained above, in the vehicle position confirmation device according to the present invention, by observing changes in the irradiation pattern by one or more beams generated from the light emitting part, it is possible to identify the vehicle equipped with the light emitting part and other vehicles. This has the effect of not only being able to easily and accurately determine the approach distance to another object, but also the relative angle formed between the object and the other object.
