DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a block diagram showing a first embodiment of the vehicle alarm device of the present invention. As shown in FIG.
0, the microphones 101 to 104 are located at the right front, right rear, left front, and left rear with respect to the traveling direction Y, respectively.
Is provided. The microphones 101 to 104 function as sound collecting means and convert sound collected from outside the vehicle into a sound electric signal.

The vehicle 100 also includes amplifiers AP1 to AP4 for amplifying the sound electric signals output from the microphones 101 to 104, and amplifiers AP1 to AP4.
Are provided with filters F1 to F4 for removing a specific frequency band from the amplified sound electric signal. Filter F1
The specific frequency band to be removed by F4 is a frequency band different from the frequency band of the alarm sound, and noise other than the alarm sound can be removed by removing the frequency band.

The vehicle 100 further includes filters F1 to F1.
A multiplexer 105 for selecting one of the sound electric signals from F4; an A / D converter 106 for sampling the sound electric signal selected by the multiplexer 105 and performing analog / digital (hereinafter, A / D) conversion; Is provided.

The digital signal output from the A / D converter 106 is supplied to a microcomputer 107
(Hereinafter referred to as μCOM). This μCOM1
Reference numeral 07 denotes a central processing unit (CPU) 107a that performs various types of processing according to programs, a ROM 107b that is a read-only memory that stores processing programs performed by the CPU 107a, a work area used in various types of processing in the CPU 107a, and various types of data. And a RAM 107c which is a readable and writable memory having a data storage area for storing the data.

The ROM as alarm sound data storage means
Warning sound data obtained by sampling sounds such as a “siren sound” of an emergency vehicle, a “horn sound” of various vehicles, and a “warning sound” of a railroad crossing are stored in the 107b in advance. The CPU 107a detects the occurrence of an alarm sound and identifies the type of the alarm sound based on a comparison between the sampling value of the electric sound signal and the alarm sound data. The CPU 107a also includes four microphones 101 to 1
Based on the loudness of the sound collected by 04, detection processing of the direction of occurrence is performed.

Further, as shown in FIG.
08a are provided with vibrators A to D for notifying the driver of the hearing impaired that the generation of the alarm sound can be identified by its type and its generation direction. The vibrators A to D are provided in accordance with the directions in which the alarm sounds are generated, such as front, rear, right, and left. Then, the CPU 10
Reference numeral 7a controls the vibration of the vibrators A to D via a parallel interface (hereinafter, parallel I / F) 109 that converts a serial control signal for controlling the vibrators A to D into parallel.

More specifically, the CPU 107a operates as shown in FIG.
As shown in (1), the type of the alarm sound is notified by vibrating in eight types of vibration rhythm patterns according to the type of the alarm sound. The vibration rhythm pattern is stored in the ROM 107b as rhythm pattern storage means in advance. The CPU 107a also includes a CPU 107a
Vibrates the vibrators A to D according to the direction in which the warning sound is generated, thereby notifying the hearing impaired person of the direction in which the warning sound is generated.

Further, the μCOM 107 corrects the frequency fluctuation of the sound outside the vehicle according to the temperature, or the frequency fluctuation of the sound outside the vehicle according to the moving direction of the sound (to approach or move away) and the acceleration of the own vehicle. Temperature sensor 110 and an acceleration sensor 111 are connected.

The details of the operation of the above-described vehicle notification device will be described below with reference to the flowchart of FIG. 5 showing the processing procedure of the CPU 107a. The CPU 107a
For example, when an ignition switch (not shown) is turned on, the operation starts, and in an initial step (not shown),
Initial settings of various areas formed in the RAM 107c are performed. Note that the CPU 107a may be operated by an operation start switch attached to the vehicle notification device.

Thereafter, the CPU 107a performs a sound collection process (step S1). Hereinafter, a procedure of the sound collection processing performed by the CPU 107a will be described. The CPU 107a outputs the switching signal S1 to allow the multiplexer 105
Is performed. The multiplexer 105 is connected to the CP
In response to the switching signal S1 from the U107a, the four sound electric signals input in parallel are sequentially switched at predetermined time intervals and supplied to the A / D converter 106 in series. Then, the A / D converter 106 samples the supplied sound electric signal at a sampling cycle shorter than a predetermined time, performs A / D conversion, and outputs the result to the CPU 107a.

The CPU 107a includes an A / D converter 10
The digital value of the sound electric signal output every time sampling is performed is taken in, and sequentially stored in the RAM 107c.
With the above sound collection processing, the RAM 107 of the μCOM 107
In c, sampling data composed of a plurality of digital values obtained by sampling each sound electric signal collected by the microphones 101 to 104 is stored.

Next, the CPU 107a performs processing for correcting the alarm sound data (step S2). Specifically, correction is performed for the frequency fluctuation of the outside sound as described below. That is, V = velocity of sound (m / s), fo = frequency of sound source (H
z), f '= frequency of sampling value (Hz), Us = speed of moving sound source (m / s), Uo = speed of vehicle (m / s), the frequency (Hz) of sampling value is given by equation ( As shown in 1) and (2).

When the sound source is approaching f '= fo. (V + Uo) / (V-Us) (1) When the sound source is away f' = fo. (V-Uo) / (V-Us) (2)

From the above equation (1), if the vehicle accelerates while the sound outside the vehicle is approaching, the sound outside the vehicle will be heard steadily higher. Conversely, if the vehicle is decelerating, it can be seen that the sound outside the vehicle sounds lower and lower. On the other hand, when the sound outside the vehicle is moving away from the above equation (2), the sound outside the vehicle is heard as if the vehicle is accelerating. Conversely, if the vehicle is decelerating, the sound outside the vehicle will be heard more and more.

In order to correct such a frequency variation of the outside sound, the CPU 107a first functions as a moving direction detecting means in the correction processing, and determines the moving direction of the outside sound (the direction of approaching or the direction of moving away) from the sampling value. Is detected. After that, the alarm sound data is corrected based on the detected moving direction and the acceleration detected by the acceleration sensor 111.

As described above, by correcting the warning sound data based on the moving direction and acceleration of the outside sound and the outside temperature, the warning sound can be accurately obtained even if the frequency of the outside sound fluctuates due to the above factors. Data can be generated and its type can be identified.

Further, even if the sound speeds constituting the above equations (1) and (2) fluctuate due to the temperature outside the vehicle,
Frequency fluctuation occurs. Therefore, the CPU 107a functions as a temperature correction unit, and corrects the alarm sound data based on the temperature detected by the temperature sensor 110 in the correction processing to further correct such frequency fluctuation of the vehicle sound. In the above correction processing, the alarm sound data is corrected, but the sampling value may be corrected.

By the way, sound has the basic property of traveling straight like light, but in some cases, the path may bend. This is a phenomenon called “refraction”. Refraction means that when sound passes through a boundary between two types of media, the path is bent, but refraction may occur even in the same medium such as air. That is, since the speed of sound in the air changes with the temperature, if the temperature of the same air is different, the medium will not be the same.

A distant sound that could not be heard during the daytime may be heard at night, but this is due to refraction due to a difference in temperature. In other words, in the daytime, the temperature is higher near the surface of the ground, and the sound speed is high, so the sound is continuously refracted toward the sky, but at night, the temperature of the surface temperature decreases, the sound speed decreases, and the sound refracts toward the surface of the surface. Sound is transmitted far away to go.

Focusing on the above, the CPU 107a
When the temperature detected by the temperature sensor 110 is high, the amplifier gains of the microphones 101 to 104 are increased, and when the temperature is low, correction is performed to decrease the amplifier gain. Thereby, even if the temperature differs, the sound collecting ability of the microphones 101 to 104 can be made uniform.

Then, the CPU 107a
The sampling data stored in c is compared with the various types of alarm sound data (step S3). Then, the CPU 107a functions as an occurrence detection unit, and detects that an alarm sound is generated outside the vehicle based on the comparison result. That is, as a result of the comparison, if there is no alarm sound data that matches the sampling data (N in step S4), it is determined that no alarm sound has been generated, and the process returns to step S1 again.

On the other hand, if there is alarm sound data that matches the sampling data (Y in step S4), CP
U107a determines that an alarm sound has been generated, and then acts as a direction detecting means, and performs a direction detection process for detecting the direction of occurrence (step S5).

Hereinafter, the direction detecting process will be described. C
The PU 107a first uses the sampling data stored in the RAM 107c to control the microphones 10 in four directions.
The ratio of the magnitudes of the electric signals output from 1 to 104 is obtained. Then, according to the determined ratio, the sound is generated from any of the eight directions of front, rear, left, right, left front, right front, left rear, and right rear, and is detected in accordance with the detected generation direction. The vibrators A to D to be vibrated are determined.

The above-mentioned direction detection processing is specifically, for example,
When the electric signal output from the microphone 102 disposed on the right rear of the vehicle 100 is the largest, it is determined that the alarm sound is generated from the rear right. Then, both the right flag and the rear flag formed in the RAM 107c corresponding to the right and rear vibrators are turned on, and the vibrators A to D to be vibrated are determined.

As described above, the detected generation direction is
For example, when the right rear direction is an intermediate direction between the right direction (first generation direction) and the rear direction (second generation direction), by vibrating the two right and rear vibrators simultaneously,
Front, rear, left, right, front left, front right, front left, rear left and rear right eight with four vibrators provided corresponding to front, rear, left and right directions.
The generation direction of the direction can be notified.

Next, the CPU 107a functions as an identification means, identifies the type of alarm sound, and performs an identification process for determining a vibration rhythm pattern corresponding to the alarm sound (step S).
6). That is, in the above-described identification processing, the CPU 107a
In step S3, the type of alarm sound is identified by determining which type of alarm sound data matches the sampling data. If the alarm sound data that matches the sampling data is siren sound alarm data, a flag indicating continuous vibration is turned on. If it is a horn sound, a flag indicating intermittent vibration 1 is turned on. For example, the flag indicating the intermittent vibration 2 is turned on (see FIG. 4).

Thereafter, the CPU 107a generates a serial control signal S2 according to the flag indicating the vibrating body turned on in step S5 and the flag indicating the vibration rhythm pattern turned on in step S6 (step S7).
After outputting the generated serial control signal S2 for a predetermined period of time (step S8 and Y in step S9), the output of the serial control signal S2 is stopped (step S8).
10) Return to step S1 again.

The serial control signal S2 is a parallel I / F
The signal is converted into a parallel control signal by 109 and output to the vibrators A to D, respectively. Upon receiving the parallel control signal, among the vibrators A to D, the vibrator determined in step S5 vibrates according to the vibration rhythm pattern determined in step S6.

By the above operation, the CPU 107a can vibrate the vibrating body among the vibrating bodies A to D according to the direction in which the alarm sound is generated in a vibration rhythm pattern corresponding to the type of the alarm sound. Therefore, the deaf driver
From the vibration rhythm pattern, it is possible to recognize the type of the generated alarm sound, such as a "horn sound" from another vehicle, a "siren sound" from an emergency vehicle, and the like. For this reason, before looking outside the vehicle, the type of alarm sound can be recognized, and what kind of action should be taken can be determined, so that the action for the alarm sound can be promptly performed.

The driver of the hearing impaired can recognize from which direction the alarm sound is generated by vibrating the vibrating bodies A to D. For this reason, the situation can be grasped by quickly visually observing another vehicle, an emergency vehicle, or the like that is generating the alarm sound. As is clear from the above operation, it can be seen that the vibrating bodies A to D and the CPU 107a that controls the vibration of the vibrating bodies A to D constitute the notification unit 200.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a block diagram showing a second embodiment of the vehicle alarm device of the present invention. In the same figure, the same parts as those in the first embodiment described with reference to FIG. The configuration different from the first embodiment of FIG. 2 is that the serial control signal S2 is transmitted to the transmitter 1 via a serial interface (hereinafter, serial I / F) 112.
13 is output. This transmitter 113
Transmits the supplied serial control signal S2 to the outside via the antenna AT1.

As shown in FIG. 7, the vibrators A to D are provided in a portable cushion 108b. In the cushion 108b, a receiver 114 for receiving the transmitted serial control signal via the antenna AT2 and a parallel I / F 11 for receiving the received serial control signal are provided.
And a μCOM 116 for outputting to the vibrating bodies A to D via the control unit 5.

In the first and second embodiments described above, the detection of the alarm sound and the identification of the type are performed based on the sounds collected by the microphones 101 to 104. With this configuration, only the hearing-impaired driver can easily detect the generation of the alarm sound and identify the type only by providing the microphones 101 to 104 and the ROM 107b storing the alarm sound data in the vehicle.

However, for example, both the alarm generating side such as an emergency vehicle or a level crossing barrier, and the general vehicle side,
Equipped with a transceiver capable of wireless communication, the alarm generation side sends a signal to notify the generation of alarm sound and the type of alarm sound, etc., to the general vehicle side, directly or by wireless installed on the road You may make it transmit via a roadside device which can communicate.

In this case, the microphones 101 to 10
4, the detection of the alarm sound and the type identification accuracy are improved. However, it is necessary to prepare a transceiver on the side where an alarm occurs, such as an emergency vehicle or a circuit breaker.
There is also a problem in cost. Also, horn sounds from other vehicles not equipped with a transceiver cannot be detected.

In the first and second embodiments, the generation of the alarm sound, its type and its generation direction are notified by the vibration of the vibrators A to D. However, the notification by a display or the like may be considered. . However, in this case the deaf driver always needs to pay attention to the display. Therefore, as in the first and second embodiments, the notification by vibration does not require constant attention to the display and the like, and is more desirable for ensuring the safety of the driver of the hearing impaired.

In the first and second embodiments, the vibrating body according to the direction in which the alarm sound is generated is vibrated according to the vibration rhythm pattern according to the type of the alarm sound. But,
For example, during the first fixed time, all the vibrators A to D may be vibrated according to the vibration rhythm pattern corresponding to the type of the alarm sound, and then the vibrators according to the generation direction may be continuously vibrated. Conversely, after the vibrating body corresponding to the generation direction is continuously vibrated or the like during the first fixed time, all the vibrating bodies A to D may be vibrated according to the vibration rhythm pattern corresponding to the type of alarm sound. Good.
