Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to driving operations that particularly require safety confirmation, such as changing direction while driving, parking or parking while driving in reverse, or entering a garage. The present invention relates to a vehicle safety confirmation support device that supports safety confirmation by calling the driver's attention to safety confirmation when performing safety confirmation.

[Background Art] As is well known, in recent years, various devices and systems for accident prevention or safety confirmation have been devised for the purpose of further improving the safety of vehicles such as automobiles.

That is, for example, a speed warning device that issues an alarm when the speed exceeds a certain value, a door alarm device that issues an alarm if one of the doors is not securely closed when starting the vehicle, or an obstacle detection sensor ( For example, warning systems that detect obstacles using laser radar, ultrasonic sensors, cameras, etc. and issue warnings to prevent accidents such as collisions and collisions have been devised, and some of these systems have already been put into practical use. There is.

By the way, when the above-mentioned device or system detects a predetermined condition that should issue a warning and calls the driver's attention to safety confirmation, it does not just display a lamp on the display device, but also uses a buzzer or other device. By issuing an audible warning such as a chime or voice, the driver's attention can be more reliably called.

[Problems to be Solved by the Invention] However, with the above-mentioned conventional device that uses sound to alert the driver to safety confirmation, for example, when the volume of a conversation between passengers or the volume of an in-vehicle audio device is high, , or when the noise outside the vehicle is severe, the driver may not be able to hear the warning sufficiently even if there is a warning.

In addition, in systems that aim to prevent accidents by warning devices such as those described above, if there is a risk of an accident, this will be automatically detected and a warning will be issued, reducing the burden on the driver. On the other hand, there is a problem in that the driver becomes too dependent on the driver or the equipment, and the most basic and important visual safety confirmation tends to be neglected.

This invention was made in view of the above-mentioned problems, and provides a more reliable system by emitting a tactile alarm when an operating member for performing an operation that requires safety confirmation is actually operated. Another object of the present invention is to provide a vehicle safety confirmation support device that can call the driver's attention and support safety confirmation.

Furthermore, the third invention of the present application is a vehicle safety confirmation support device, which includes a detection means for detecting that an operating member operated when reversing the vehicle is actually operated, and a sensor of the detection means. The seat driving means receives a detection signal and causes a predetermined dynamic change in the driver's seat.

Effects of the Invention According to the first invention of the present application, since the detection means and the seat drive means are provided, when the operation member is actually operated, a predetermined dynamic change occurs in the driver's seat. This allows the driver to experience this dynamic change. In other words, it is possible to notify the driver that a safety check is necessary by appealing to their senses, and more reliably alerts the driver to the safety check, compared to conventional systems that issue warnings using lamps or sounds. can do. As a result, it is possible to effectively prevent insufficient or forgotten safety confirmation when operating the above-mentioned operating members, to encourage and develop the habit of visually checking safety, and to improve vehicle operation safety. .

Further, according to the second invention of the present application, since the detection means and the seat driving means are provided, the driver's seat is rotated by a predetermined angle when changing the course of the vehicle. That is, when changing course, it is possible to inform the driver that safety confirmation is necessary by appealing to his senses, and it is possible to achieve the same effect as the first invention. Furthermore, when changing course, the driver's seat is rotated by a predetermined angle in the direction of the change of course of the vehicle, making it easier to visually confirm safety.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the vehicle according to the present embodiment has a turn signal lamp (not shown) on the side of the steering column 12 that blinks a turn signal lamp (not shown) when changing direction while driving, such as when changing lanes or turning a corner. A switch 7 is attached, and the blinker switch 7 is electrically connected to a controller 10 housed in, for example, an instrument panel 11.

Further, as shown in FIG. 2, the driver's seat 2 of the above-mentioned automobile is supported by a center column 16 disposed approximately in the center of the seat cushion 3, and the center column 16 is supported by, for example, a movable notebook slide device 15. It is rotatably supported on the side member 15a. A mounting plate 16a is integrally formed on the upper end side of the center column 16, and the mounting plate 16a is buried in the internal bottom surface of the notebook cabinet 3 and is integrated with a frame member (not shown) of the notebook cabinet 3. is combined with Furthermore, a gear member 17 made of, for example, a spur gear is fixed to the middle of the center column 16, and is arranged coaxially with the column 16, and when this gear member 17 is rotationally driven, the center column 16 is rotated. The seat cushion 3 is also rotated around the central axis of the center column 16.

On the other hand, an electric motor 8 for driving the seat 2 is attached to the movable member 15a, and a drive gear 9 that meshes with the spur gear 17 (gear member) is fixed to the output shaft of the motor 8. . The electric motor 8 is connected to the controller 10 so as to be able to send and receive signals, and when the motor 8 is rotated by a predetermined amount by a control signal from the controller IO, the gear member 17 is also rotated by a predetermined angle via the drive gear 9. The seat cushion 3 (that is, the entire seat 2) can be rotated by a predetermined angle.

As shown in FIG. 4, the controller IO includes an input section 10a that can receive an output signal from the blinker switch 7.
, a direction determining section 10b that determines the direction of change in course, and a motor control section 10 that outputs a control signal to the electric motor 8.
When the turn signal switch 7 is operated when changing the course and the output signal from the turn signal switch 7 is input to the controller 10, the controller 10 judges the direction of the change of course and controls the electric motor 8. A control signal is output, and the motor 8 is driven to cause the driver's seat 2 to undergo a predetermined dynamic change (that is, rotational movement).

The turn signal switch 7 is provided with a switch circuit for blinking and clearing the turn signal lamp (not shown), and by connecting this switch circuit and the input section 10a, the turn signal switch 7 is turned ON10. F

If an operation is detected (in the case of YES), the direction of course change (that is, right turn, left turn, etc.) is determined in step #2. Based on this determination result, the electric motor 8 is rotationally driven in a predetermined direction, that is, in a direction that rotates the seat 2 in the direction of changing the course (step #3).
, when it rotates by a predetermined amount of rotation, the drive is stopped (step #4).

As a result, via the gear mechanism 9.17, the center column 16
is rotated by a predetermined angle, and the entire seat 2 is rotated by a predetermined angle α° in the course change direction, as shown by the broken line curve in FIG.

By experiencing this rotational movement of the seat 2, the driver is alerted to safety confirmation when changing directions. In addition, since the Note 2 is rotated in the direction of changing course, when visually checking the direction and checking the door mirror, the driver's head movement should be reduced to ensure smooth confirmation operations. I can do it.

It should be noted that if the rotational movement of the seat 2 is too large, it may have an adverse effect on other driving operations such as steering wheel operation and brake operation.In order to prevent this, in this embodiment, the seat 2 The rotation angle α° of No. 2 is set within a small angle range (for example, 5° or less).

Then, in step #5, the turn signal switch 7 is
FF operation (reset) is detected, and when the detection result becomes YES, the motor 8 is driven to rotate in the opposite direction in step #6, and when the motor 8 has been rotated by a predetermined amount, the drive of the motor 8 is stopped. (Step #7
). As a result of the second result, the notebook 2 is returned to the neutral position shown by the solid curve in FIG.

As explained above, according to this embodiment, when the blinker switch 7, which is an operating member operated when performing an operation that requires safety confirmation (changing the vehicle's course), is actually operated, , it is possible to cause the driver's seat 2 to undergo a predetermined dynamic change (a rotational movement of a predetermined angle), and to allow the driver to experience the rotational movement of the seat 2. In other words, it is possible to notify the driver that a safety check is necessary by appealing to their senses, and more reliably alerts the driver to the safety check, compared to conventional systems that issue warnings using lamps or sounds. can do. As a result, it is possible to effectively prevent insufficient or forgotten safety confirmation when operating the blinker switch 7, that is, when changing lanes or turning corners, and to encourage and develop the habit of visually confirming safety. Safety can be improved.

In addition, since the seat 2 is rotated in the direction of the vehicle's course change, when visually checking the direction and checking the door mirror, the driver's head movement is minimized and the checking operation is performed smoothly. It is possible to do so.

In addition, in the above embodiment (first embodiment), the turn signal switch 7
When operated, the seat cushion 3 (in other words, the entire seat 2) was configured to rotate 9 times, but it is also possible to rotate the seat back or headrest without moving the seat cushion. .
