A red light emitting diode is used for the red light 204 and a blue light emitting diode is used for the blue light 206, so that power saving is achieved as compared with a fluorescent light or the like. The vehicle inductor is installed at the entrance-side pole of the parking space or at a predetermined distance from the entrance-side pole, and in the present embodiment, it is attached to both short columns 10 so that a driver who intends to park the vehicle can easily see and hear.

Then, a microcomputer is housed in a control operation panel attached to the short column 10 and controls a lamp display, a warning sound and the like. As shown in FIG. 4, the microcomputer 100 uses the approach signal from the approach detection sensor 12,
Approach signals from the sensors 24a, 24b, 34a, 34b,
The input interface 102 (hereinafter, the interface is referred to as “I / F”) connected so as to receive the stop signal from the stop sensor 43 and the detection signal such as the approach signal from the input I / F are acquired, RO storing a program for executing the flowchart shown in FIG.
A CPU (Central Processing Unit) 104 for reading out an instruction or the like from an M (Read Only Memory) 103 and executing the instruction, and a C
A RAM (Random Access Memory) 106 connected to the PU 104 and temporarily storing data, and a CPU

Next, the operation relating to the vehicle inductor in which the electric processing relating to the parking guidance device is performed will be described (FIGS. 4 and 5). Now, when the vehicle 3 enters the parking space S in the rearward direction, an entry signal is generated from the entry detection sensor 12 and given to the input I / F 102. Microcomputer 100
Determines that the vehicle 3 has entered the parking space S (step S100).

Further, if the vehicle 3 travels backward and reaches between the two central poles 20, 20, and if the distance between the right central pole 20 and the vehicle 3 accidentally enters within a predetermined distance, An approach signal is generated from the sensor 24b and given to the input I / F 102. Microcomputer 100
Judges that the vehicle 3 has approached the right central pole 20 too much by the approach signal (step S106), and outputs I / F1
At the same time when the red light 204 of the vehicle inductor 200 is blinked via 12, the voice synthesizing circuit 110 operates to output the output I / F.
From the speaker 202 via 112, the “right pole 20
Is too close to. "A warning sound is emitted (step S1
08). The driver adjusts the vehicle 3 to the center of both center poles 20 by watching the warning sound and the blinking of the red light 204. As a result, the approach signal from the central sensor 24b disappears, the warning sound disappears, and the red lamp 204
Also goes out.

On the other hand, the vehicle 3 travels backward and reaches between the two central poles 20, and the left central pole 20 and the vehicle 3
If the distance between the input side I and the input side is mistakenly entered within a predetermined distance, an approach signal is generated from the sensor 24a in the left side central portion and the input I / F
Give to 102. The microcomputer 100 determines from the approach signal that the vehicle 3 is too close to the left center pole 20 (step S106), blinks the red light 204 of the inductor 200 via the output I / F 112, and at the same time,
The voice synthesizing circuit 110 operates and the warning sound is emitted from the speaker 202 via the output I / F 112, "Too close to the left pole 20" (step S108). The driver adjusts the vehicle 3 to the center of both center poles 20 by watching the warning sound and the blinking of the red light 204. As a result, the approach signal from the central sensor 24a disappears, the warning sound disappears, and the red lamp 204 also goes out.

Further, if the vehicle 3 travels backward and reaches between the rear poles 30, 30, and if the distance between the left rear pole 30 and the vehicle 3 is mistakenly entered within a predetermined distance, the left side is left. An approach signal is generated from the rear sensor 34a and given to the input I / F 102. The microcomputer 100 determines from the approach signal that the vehicle 3 is too close to the left rear pole 30 (step S110), and outputs the red light 204 of the vehicle inductor 200 via the output I / F 112.
At the same time as blinking, the voice synthesizing circuit 110 is activated and a warning sound is emitted from the speaker 202 via the output I / F 112, "Too close to the left pole 30" (step S112). The driver corrects and moves the vehicle 3 to the center between the two rear poles 30 by watching the warning sound and the blinking of the red light 204. This allows the rear sensor 3
The approach signal from 4b disappears, the warning sound disappears, and the red lamp 204 also goes out.

When the vehicle 3 travels backward and the rear tire of the vehicle 3 comes into contact with the vehicle stop 41, the stop sensor 43 generates a stop signal and the input I / F 1
Give to 02. The microcomputer 100 determines from the stop signal that the vehicle 3 has been parked (step S1).
14), the blue light 206 of the vehicle inductor 200 is turned on via the output I / F 112. At the same time, the speech synthesis circuit 11
0 operates to output the speaker 202 via the output I / F 112.
From, for example, an announcement sound is generated saying "I was able to park correctly. Pull the parking brake, lock the key and go out" (step S116). Thus, the driver does not have to turn around behind or turn his / her neck to visually check the side of the vehicle,
The vehicle 3 can be parked smoothly. Incidentally, in step S106,
In S110, if the vehicle 3 does not enter within the predetermined distance of the poles 20 and 30, the sensors 24a, 24b, 34a, 3
4b without the approach signal being generated in step S114
Proceed to.

In the present embodiment, the sound generating means and the light emitting means are provided, but either one of the sound generating means and the light emitting means may be provided. Also, vehicle 3 and pole 2
The determination is made based on whether or not the distance to 0, 30 is within a predetermined distance. In addition to the determination, for example, the sensors 24a, 24b, 34
By providing the distance detection function of the vehicle 3 to a and 34b,
As shown in FIG. 1, the vehicle 3 detects the distances X ₁ and X ₂ from the vehicle 3 at the distances Y ₁ and Y ₂ in the traveling direction, and the microcomputer 100 causes the inclination (X ₁ −X ₂ ) /
When (Y ₁ −Y ₂ ) is calculated and this inclination exceeds a predetermined value, the red light 204 is blinked or the speaker 2
A warning sound may be generated from 02. With such a parking guidance device, it is possible to predict the approach of the poles 20 and 30 of the vehicle 3 and avoid them more quickly.

Each of the poles 20 and 30 is entirely covered with a rubber sheet to protect the occupant from being injured even if he / she hits his / her head against the pole.
I try not to get injured when I hit the pole. Luminous paint or the like is applied to each of the poles 20 and 30 so that the pole position can be easily confirmed even at night.

In the parking guidance system constructed as described above, the first mirror 32 projects the side surface of the vehicle 3 onto the poles 20 and 30 which are erected on both sides of the parking space S, and the driver through the rearview mirror and side mirrors. The driver will be able to park smoothly without having to turn his or her head left or right to check the side of the vehicle or turn around. The second mirror 31
The presence of 0 allows the driver to know the positional relationship of the vehicle 3 in the parking space S, so that it becomes easier to park. Furthermore, when the vehicle 3 accidentally approaches the poles 20 and 30 while the driver is parked, a warning sound is generated, so the driver takes an early corrective action by receiving this caution. be able to. In addition, each pole 20,
If the vehicle 3 accidentally approaches the vehicle 30, the red light 204 blinks and the visual alert is received, so that the movement of the vehicle 3 can be corrected earlier. If the vehicle can be parked normally, the speaker 20
This is heard from 2 and a blue light 206 is turned on so that it is possible to recognize that the vehicle has been parked correctly. In this way, the driver can easily put the vehicle 3 in the parking space S while facing forward.
