Abstract

PROBLEM TO BE SOLVED: To enable a reverse running warning for a driver of a reverse running vehicle on a highway.SOLUTION: A reverse running warning device is comprised of a fixing member, a forward travelling vehicle guiding cover, a reverse running vehicle detection plate, a piezoelectric element unit, and a display means. The fixing member is fixed to the ground. The forward travelling vehicle guiding cover is rotatably attached to the fixing member by a rotating mechanism and descends when a forward travelling vehicle passes over. The reverse running vehicle detection plate is shorter than the forward travelling vehicle guiding cover and fixed on one side in a position facing the rotating mechanism. The other side contacts freely slidably with the fixing member. By impacting with a front tire of a reverse running vehicle, an impact force is generated to give a warning. The piezoelectric element unit is brought in pressure-contact with the fixing member by the impact force and generates electricity and supplies it to the display means, allowing a reverse running warning to be displayed on the display means.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a mechatronics reverse running warning device laid on a highway that urges a driver of a vehicle running backward from a junction of the highway to warn.

  In 571 reverse runs on highways that occurred from 2011 to 2013 (including cases that do not lead to accidents), it is said that about 70% of them are due to elderly people over 65 years old. It is said that this problem is becoming a social problem. As you get older, your vision, instantaneous power, and motor function decrease, and your driving risk increases. Moreover, it is clear that if you have dementia, your judgment will be poor. Since 2004, there have been more than 37 applications related to reverse running on highways.

  For example, in Patent Document 1, light waves, which are laser light, are divided into two areas in the traveling direction of the vehicle on the road surface to be detected, are projected two-dimensionally at a predetermined angle, and are scanned. There is disclosed a reverse running vehicle detection system that determines whether or not a passing vehicle is running forward and reverse from the order and / or status of reflected light from the passing vehicle and externally notifies. However, there was a drawback that the system was too complicated.

  Patent Document 2 discloses a hump construction method that is installed on a pavement and can give a greater impact to the vehicle when traveling backward than when traveling in the forward direction. However, there was a problem that there was an impact not only in reverse running but also in forward running.

  Further, in Patent Document 3, after parking at a rest facility 3 such as a highway service area or parking area and taking a break, the vehicle is informed of the exit direction when exiting from the parking lot to the main line which is a one-way street. There is disclosed a reverse running prevention device in which signs to be installed are installed at predetermined intervals along the exit direction from the approach path to the exit path. However, if the driver is dementia, it is difficult to recognize reverse running in advance.

  Further, in Patent Document 4, the first sign has a first surface and a second surface that are substantially orthogonal to each other, and the first surface is inclined outwardly with respect to the upward direction of the road. The surface is inclined obliquely outward with respect to the downward direction of the road, and the contents displayed on the first and second surfaces of the second sign are the same or different depending on the purpose, for example, against reverse running. An incline road sign is disclosed that makes it possible to do so. However, this is also not very effective when the driver is suffering from dementia.

  The problem to be solved is to provide a mechatronic reverse running warning device that is easy to install and maintain and is laid on a highway with high reliability.

  The main feature of the present invention is that a tactile sensation (sensory sensation) and visual reverse warning can be given to a driver of a vehicle traveling backward on an expressway.

  The mechatronics reverse running warning device laid on the highway of the present invention has no feeling of incongruity because the forward road is flattened by the forward vehicle guidance lid while the forward vehicle is climbing over the gentle forward vehicle guidance lid. It collides with the end of the vehicle detection plate and gives a shock to the driver. Furthermore, using this shock, electric power is generated from the piezoelectric element unit attached to the fixed member, and reverse running warnings are displayed on multiple display devices. There is an advantage that you can.

FIG. 1 is an explanatory view showing the structure of a mechatronics reverse running warning device. FIG. 2 is an explanatory view showing the operation of the mechatronics reverse running warning device.

  In the mechatronics reverse running warning device laid on the expressway, the warning vibration due to bodily sensation and visual reverse running warning display are provided without the need to connect an external power supply for the purpose of effectively warning the reverse running driver. Realized by.

  FIG. 1 is an explanatory view showing the structure of a mechatronics reverse running warning device 1 according to the present invention device. The fixing member 2 is fixed to the ground, and the fixing member 2 is rotatable by a rotating mechanism 3. The forward vehicle guide lid 4 that is attached to the front wheel tire of the forward vehicle and is fixedly mounted at a position different from the rotation mechanism 3 and collides with the front wheel tire of the vehicle from the opposite direction. The vehicle includes a reverse vehicle detection plate 5 and a control unit 6 that transmit force to the fixed member 2 via the forward vehicle guide lid 4.

  The fixing member 2 is buried in the ground 5 of the highway. When the forward vehicle guide lid 3 presses the telescopic rod 8 of the buffer member 7 according to the weight of the forward vehicle and rotates by the rotation mechanism 3 by an angle θ with respect to the horizontal plane, the inclination angle θ with respect to the upper surface of the forward vehicle guide lid and the ground becomes Nearly zero. As a result, the plane of the ground 5 and the forward vehicle guide lid 3 are flush with each other, so that it does not hinder the passing vehicle.

  The forward vehicle guide lid 4 can count the number of passing vehicles by detecting a vibration when the forward vehicle passes by placing a shock sensor on the back surface of the forward vehicle guide lid 4 when the forward vehicle passes. It becomes possible.

  Display means 5 a is attached to the reverse vehicle detection plate 5. When the tire of the vehicle traveling backward collides with the forward vehicle guide lid 4 and the reverse vehicle detection plate 5 or the protrusion 4a, the impact force generated by the collision is transmitted from the forward vehicle guidance lid 4 to the rotating mechanism 3, Further, it is transmitted to the fixing member 2. A piezoelectric element unit 10 is attached to the fixing member 2. When receiving the impact force from the front fixing member 2, electricity is generated by a repulsive force with the ground 7. In addition, since the hard material such as an iron plate is attached as a spacer between the piezoelectric element unit 10 and the ground 7, power can be generated using the repulsive force from the ground 7 effectively.

  The electric power generated by the piezoelectric element unit 10 is electrically connected to the control unit 6 by a power cable 11. The control unit 6 controls the display means 5a with a cable (not shown), and when the piezoelectric element unit 10 detects the impact force, the display means 5a displays a reverse running alarm.

  FIG. 2 is an explanatory view showing the structure of a mechatronics reverse running warning device 1a connected to the mechatronics reverse running warning device 1 of FIG. 1. Compared with FIG. 1, the display means D of FIG. It is the same except that the display means D2 is attached to the plate 5.

  The embodiment of FIG. 3 is an explanatory view showing the operation of the mechatronics reverse running warning device. FIG. 3A shows a layout in which three mechatronics reverse running warning devices 1 are arranged. The first mechatronics reverse running warning device 1 and the second mechatronics reverse running warning device 1a are electrically connected to the second mechatronics reverse running warning device 1a and the third mechatronics reverse running warning device 1b, respectively. ing.

  The control unit 6 is electrically connected to the second mechatronics reverse running warning device 1a, 1b to be connected by the connection cable 12, and displays the reverse running warning on the display means D1 of the adjacent mechatronics reverse running warning device 1. Further, if the second mechatronics reverse running warning device 1a is electrically connected to the third mechatronics reverse running warning device 1b using the connection cable 12, a plurality of mechatronics reverse running warning devices 1, 1a, 1b are displayed at the same time. It is possible to display a reverse running warning by means D, D1, and D2.

  In FIG. 3 (b), the reverse running vehicle 14 driven by the driver 13 rides over the forward vehicle guide lid 4 over the reverse running vehicle detection plate 5 of the mechatronics reverse running warning device 1. As described above, when the vehicle 13 collides with the protrusion 4a of the mechatronics reverse running warning device 1, the piezoelectric element unit 10 supplies electric power using the impact force, and the mechatronics reverse running warning device 1 and the mechatronics reverse running warning device. The display means D, D1, D2 display a reverse running warning via the control unit 6 of 1a.

  In FIG. 3C, the reversely traveling vehicle 13 moves from above the first mechatronics reverse traveling warning device 1, and the tire of the second mechatronics reverse traveling warning device 1 a is in the boundary region of the reverse traveling vehicle detection plate 5. The impact force is transmitted to the mechatronics reverse running warning device 1a by colliding with the protrusion 4a. Due to this impact force, the piezoelectric unit 10 of the mechatronics reverse running warning device 1a generates electric power, and the electric power is supplied to the third mechatronics reverse running warning device 1b by an unillustrated power cable. A reverse running warning is displayed on the display device D2 (same as D1) of the reverse running warning device 1b.

  Since the embodiment of such a mechatronics reverse running warning device is adopted, warning and display means D, D1, D2 due to a bodily sensation caused by a collision between the reverse running vehicle detection plate 5 and the tire for a driver running backward on the highway. A visual warning can be issued, and a driver who suffers from dementia has a higher recognition level, which can reduce reverse running accidents.

  When the mechatronics reverse running warning device of the present invention collides with the reverse running vehicle detection plate or the protrusion, the impact force generated by the collision is transmitted to the piezoelectric unit attached to the mechatronics reverse running warning device, and electric power is generated by the piezoelectric effect. A reverse running warning is displayed by generating power and driving the display device with this power. Here, since this apparatus does not require external power, it can be installed on highways throughout the country.
