Description

[Technical Field]

[0001] The present invention relates to a speedometer for a vehicle or the like that uses both auditory and tactile senses, and a related program. [Background technology]

[0002] Vehicle speedometers are generally presented as visual information. Therefore, drivers estimate the vehicle's speed from the engine sound produced by the vehicle and the scenery passing by, and occasionally check the speedometer to confirm that speed. However, the act of looking at the speedometer interrupts checking the road ahead, resulting in periods of inattention. For this reason, drivers tend to check the speedometer less frequently, which makes them more likely to violate the speed limit. Furthermore, recent electric vehicles often have no engine sound, or even if they do, the sound is unrelated to the vehicle's speed, making it difficult to estimate speed based on auditory information such as engine sound.

[0003] An example of this improvement is a speedometer (hereinafter referred to as an "acoustic speedometer") that uses the sense of hearing to indicate the speed level by dividing the vehicle speed (hereinafter referred to as "vehicle speed") into multiple speed ranges, and by associating each part of an ensemble made up of pieces (hereinafter referred to as "parts") played by multiple sound sources such as musical instruments and vocals with each of the speed ranges, and as the vehicle speed increases, when the speed is above the minimum speed of each speed range, it is superimposed with parts for speeds lower than that speed, and the number of parts superimposed indicates the speed level. With this sonic speedometer, the driver can distinguish between these overlapping parts of music to grasp the number of different sound sources, and on the premise that the number of different sound sources matches the number of speed range stages, the driver can grasp the vehicle speed quantitatively using the speed range stages and only using his hearing. This method has the advantage that the speed range corresponding to the vehicle speed can be grasped without using vision, and further has the feature that the vehicle speed can be grasped at all times. However, as the number of speed ranges to be set increases, the number of types of sound sources and the number of parts must be increased, which leads to problems such as the driver finding it increasingly difficult to grasp the number of types of sound sources and the number of parts that can be selected being restricted.

[0004] [Patent Document 1] Patent No. 7202514 [Patent Document 2] Japanese Patent Publication No. 2022-66116 [Patent Document 3] Japanese Patent Publication No. 2022-110180 Summary of the Invention [Problem to be solved by the invention]

[0005] As explained above, the sound speed meters proposed so far require a limited number of speed ranges to be set compared to the number of sound sources in a piece of music. Therefore, a sound speed meter that can set a large number of speed ranges is needed even for pieces with a small number of sound sources or parts. [Means for solving the problem]

[0006] This invention allows for the representation of four different numbers, 00, 01, 10, and 11, even when numbers, which only require two types of digits like binary numbers, are expressed in two digits. This is a sound velocity meter that reduces the number of sound sources by focusing on this fact. If we apply this to the last two digits of a quaternary number system (a base system that uses four numbers from 0 to 3), for example, there are 16 possible numbers from 00 to 33, but each digit only uses four possible numbers: 0, 1, 2, and 3. Nevertheless, it is possible to represent 16 different numbers. In this invention, three types of first-digit values, for example, omitting the zero (0) in a quaternary number, which indicate the stages of the speed range, are respectively replaced with the output of three types of sound sources and part songs, and for the second-digit values, new part songs are superimposed on the original song to make up for the lack of part songs, using several types of metronome sounds with different tempos that can be generated according to time information such as the beat, tempo, and divisions of repeated measures shown in the musical score that makes up the song, or several types of rhythm sounds produced by multiple sound sources that are repeated on a measure-by-measure basis. Furthermore, the vibration units installed on the steering wheel and seats of the vehicle output vibrations with the same signals as the in-car output of each part of music, so that the part of music that the vibration unit is indicating or selecting can be made clear even in a moving car with a lot of vibration. The timing at which the vibrations are synchronized with the music is measured in units of measures or beats within the part of music, and a rule has been established that the length of these times "represents a numerical value." This allows the driver to determine the units of measures and beats in a part of music by using the presence or absence of vibrations caused by the same signals as the sound, even in a vehicle that is moving with a lot of vibration noise, making it easy to perceive, and the sonic speed meter allows the driver to always understand the stages of the speed range based on the numerical values ​​that they represent. These are the most important features. [Effects of the Invention]

[0007] The sound speed meter of the present invention is a sound speed meter in which various sound sources output sounds of music or the like into a vehicle according to musical scores or the like, divides the speed of the vehicle into a plurality of stepwise speed ranges, expresses the numerical values ​​indicating the steps of the speed range in a positional radix system of decimal or smaller (a method of expressing a numerical value by arranging several digits), converts the numerical value of each digit of the radix system into an output time width in units of measure time or beat time in the music, and further outputs vibrations of the output time width into the vehicle, which makes it possible to reduce the number of types of numerical values ​​(radixes) required, thereby having the effect of making it possible to use music or the like consisting of fewer sound sources or parts. Furthermore, the value of the first digit of the base number is expressed by the type of sound source (1) that constitutes the music piece, the type of part music (1) for the sound source (1), or the measure time (1) or beat time (1) in the part music (1); The second digit of the base number is set by superimposing on the music piece a part (2) such as a metronome sound or a repeating rhythm sound that can be generated based on the performance conditions specified on the score of the music piece, and distinguishing the type of part (2), the type of sound source (2) set for the part (2), the measure time (2) and the beat time (2) within the part (2), so that the sound speed meter can be used even for music pieces or radio broadcasts that only have one type of sound source or part. This allows the range of music that drivers can choose to be expanded from ensembles to solo pieces, and also has the effect of enabling the use of sound sources that are not necessarily music pieces, such as radio broadcasts. In addition to these, since the types of sound sources and their part music can be reduced, it becomes easier for the driver to learn in advance how the speed range stages relate to the sound sources and part music, and it also has the effect of making it easier to lower the level of musical talent required to grasp the bar time, beat time, etc. Furthermore, by outputting auditory information and tactile information in the same or synchronized signal waveforms inside the vehicle, it becomes possible to clearly select specific notes, etc., indicated in the measure time or beat time of the part music from among noise and vibrations, even in a vehicle that is moving with a lot of vibration noise. Furthermore, the sonic speedometer of the present invention allows passengers other than the driver to only perceive that music sounds are being output inside the vehicle, but the driver can always understand the speed of the vehicle he or she is driving as a speed range step number through hearing and touch, making it possible to always maintain the sound environment inside the vehicle in the best possible state, etc. Furthermore, while a normal speedometer that uses vision causes the driver to become distracted from the road ahead, which can lead to accidents, the sonic speedometer of the present invention has the characteristic of not causing such distraction from the road ahead.

[0009] Various sound sources output music as auditory information inside the vehicle according to musical scores, etc., and the vehicle speed is divided into multiple step-by-step speed ranges, the number of steps in the speed range is the vehicle speed, and the number of steps is calculated using the number of types of sound sources that make up the music output inside the vehicle and information obtained from the musical scores used by those sound sources, which is a sound speed meter. The fewer the number of sound sources and part music types used, the simpler the system can be, and the wider the selection of available music can be. Therefore, in the sound velocity meter of the present invention, the number of steps is reduced by using a decimal or smaller positional radix system (a method of expressing a number by arranging several numbers), thereby reducing the number of types of numbers used by each digit and the number of sound sources and part songs required. Furthermore, the numerical value of each digit is made to be able to easily grasp the specific part of the part music in terms of measure time or beat time by combining the part music to be used with the same vibration as the signal waveform of the part music, and to make it possible for the driver to easily grasp the number of stages of the speed range of the vehicle. [Example]

[0010] 1 is a layout diagram showing an outline of the device of a vehicle embodying the present invention, in which a drive unit 1 consisting of a motor, an engine, etc. drives a pair of wheels 3 via a transmission 2. The drive unit 1 is rotated by supplying energy from an energy source 9, which stores electricity, gasoline, etc., under the control of an energy control unit 8. This vehicle is driven by controlling the vehicle speed with a speed setting value input unit 7, which corresponds to the accelerator pedal and brake pedal in the vehicle, the running speed is detected by a speed detection unit 5, and the direction is controlled with a steering wheel 17. Although the explanation up to this point has been somewhat abbreviated, it is a general form of driving control for automobiles and the like.

[0011] The vehicle also has a sign recognition unit 4 that recognizes speed limit signs on the road and a GPS (Global Positioning System) information detection and processing unit 6 installed in appropriate locations. Data generated by these units is sent to a control unit 10, which will be explained next. The control unit 10 reads data from the memory unit 12, including sound sources and musical scores, and performs necessary data calculations and control. The display unit 11 serves as the man-machine interface. It also controls the signal generator 13, which converts the data from the memory unit 12 into specific signals, to generate signals for instruments and voices, and to specify the volume. The music information in the memory unit 12 may be compressed audio data (MP3), lyrics, musical scores, music, or MIDI. The music data generated by the instrument signal generator 13 is converted from digital to analog via a D / A converter 14, then amplified by an amplifier 15 and output from speakers 16 inside the vehicle. The bundle vibrator 18 and seat vibrator 20, installed on both the right and left sides, generate vibrations that are the same as or synchronized with the output of the speakers 16, transmitting them to the steering wheel 17 and the driver's seat 19. [Example]

[0012] First, the information in the musical score used by the present invention will be explained. Figure 2 shows an example of notes in a musical score. For the sake of explanation, the musical score is divided into measures (1) through (6). In the upper left corner of measure (1), there is the symbol 30, which is made up of a quarter note and "=60," indicating the tempo (speed) of the performance. This indicates that the music is played at a speed of 60 quarter notes per minute. Furthermore, there is a tone symbol in measure 1 and a symbol 31 next to it indicating (4 / 4), which indicates that the song is in "4 / 4 time" and, more specifically, that the type of note that forms the basis of one beat (called a "note value") is a quarter note, and that one measure consists of four beats. These symbols vary depending on the song, and each song uses these symbols to define the relationship between the tempo (speed) and notes of its performance. The time that one beat occupies on the score will be referred to as "beat time" below, and the time that one measure occupies on the score will be referred to as "measure time" below, and these are defined as units of time. The present invention allows for the generation of musical parts such as metronome sounds based on performance information other than notes and rests required for performance as specified by the composer, as well as rhythm sounds that repeat in units of measure time or multiple measures as a unit, to be superimposed on the original musical piece as musical parts and output to the vehicle. This utilization is another feature. Next, let's explain the notes in Figure 2. Note 32 shown in measure 2 is a quarter note, note 33 shown in the following measures is an eighth note, rest 34 is a quarter rest, rest 35 is an eighth rest, and note 36 is a half note. There are many other types of notes and rests, but we will not explain them here to avoid complicating things. The above information is written on the notes, and the following embodiment will be explained on the assumption that this information is used.

[0013] In addition, in order to present the step numbers of the step-divided speed range as speed information, the example of the sound speed meter of the present invention outputs a song selected by the driver from the speaker 16 in FIG. 1 into the vehicle, and vibrations with the same signal waveform as the song or a signal waveform synchronized with the song are output in units of beat time or bar time from the vibrating units 18 on the left and right hand sides of the steering wheel 17 in FIG. 1 and the vibrating unit 20 on the seat 19, and this function is used when necessary. The control unit 10 controls the output of either or both of the vibration units 18 on the left and right sides in FIG. 1, and also the vibration from the vibration unit 20 of the seat 19. [Example]

[0014] Next, an example of vibration of the sound velocity meter used in the present invention will be described with reference to FIG. Figure 3 shows the "vibration output time for the speed range," and we will explain this assuming that the score of the music being used indicates as performance information that the playing speed is quarter notes repeated 60 times per minute, the time signature is 4 / 4, and each measure contains four quarter notes or notes equivalent to quarter notes. The present invention is based on the premise that music based on this information is output inside the vehicle, and furthermore, the driver and passengers are able to listen to the music at all times. These assumptions are the same for all the following embodiments, but the performance information and music pieces described above are merely examples for the convenience of explanation.

[0015] The vertical axis of Figure 3 shows the number of speed ranges indicated in decimal numbers starting from 0 in the first column, and the second column shows four speed ranges in km / h as examples: "0-10," "10-20," "20-30," and "30-40." The horizontal axis represents the vibration output time, and the items are shown in the third column from the left, from top to bottom: "bar time," "beat time," and "vibration amount." The top row of measure times has a double arrow indicating the range of time and numbers 1 to 4 to distinguish that range. The next line of beat times shows the passage of beat time in the order of (1) to (4), and the same passage of time (1) to (4) is repeated each time the bar time changes. The next row of vibration magnitude shows the vibration output corresponding to the speed range as a pattern, represented by the presence or absence of a square with a series of vertical bars. During the beat time indicated by the vertical bar, vibrations with the same signal waveform as that of a specific part of the music being output to the vehicle, or a signal waveform synchronized with that, are output from the steering wheel vibration unit 18, the seat vibration unit 20, etc. in Figure 1. Next, the presence or absence of vibration in each speed range and synchronization with a specific part of the music to be output in the car will be described.

[0016] When the speed range of the vehicle is 0 to 10 (Km / h), During all beats of the measure (here, (1) to (4)), there is no vibration output synchronized with the sound of the notes in the music (hereafter referred to as "Pattern 0"), and only the music is output inside the car. As a result, the driver will determine that the speed of the traveling vehicle is in the speed range of 0 to 10 (Km / h), which is the 0th step. 3, measure times are shown as 1 to 4, but as long as the vehicle speed range is within the range of 0 to 10 (Km / h), the output of pattern 0, which is the same as measure time 1, will continue to be repeated thereafter. In this regard, for the vibration output at any of the following speed range steps, the vibration pattern will be the same as long as the vehicle continues to travel within the same speed range, and this also applies to other embodiments.

[0017] When the speed range is 10 to 20 (Km / h) in step number 1, At beat time (1) in measure time 1, the same vibration as the note in the part is output, and from beat times (2) to (4) thereafter, there is no vibration output (hereafter referred to as "pattern 1"), before moving on to the next measure time 2. At measure time 2, the vibration of pattern 1, the same as measure time 1, is output again. By repeating these vibration patterns, the vehicle speed is in the first speed range, and the driver can determine that the vehicle is traveling within a speed range of 10 to 20 (Km / h). In the above beat time (1), the vibrations mediated by the sense of touch and the musical part mediated by the sense of hearing are assumed to have the same signal waveform because the synchronized signals of the sense of hearing and the sense of touch are used as a means of selecting a specific musical part from an ensemble composed of multiple musical parts in a moving vehicle with a lot of vibration noise, and the synchronized vibrations are used as a means of clearly distinguishing the specified beat time as a musical note. This is one of the features of this invention.

[0018] In the speed range of 20 to 30 (Km / h) with step number 2, During beat times (1) and (2) in measure time 1, vibrations identical to the sounds of the notes in the part are output, and from beat times (3) to (4) thereafter, there is no vibration output (hereafter referred to as "pattern 2"), before moving on to the next measure time 2. During measure time 2, vibrations of pattern 2, the same as those in measure time 1, are output again. By repeating these vibration patterns 2, the driver can perceive the vibrations via the sense of touch and the synchronized part music through his ears during beat times (1) and (2) of measure time 1 of the part music, and from beat time (3) to beat time (4) thereafter, he can recognize that although there is an auditory perception of the music, there is no tactile vibration. By repeating these vibration patterns, the driver can determine that the vehicle speed is in the second speed range, that is, within a speed range of 20 to 30 (Km / h).

[0019] In the speed range of 30 to 40 (Km / h) with 3 stages, During beat times (1), (2), and (3) in measure time 1, vibrations identical to the sounds of the notes in the part are output, and during the subsequent beat time (4), no vibration is output (hereafter referred to as "pattern 3"), before moving on to the next measure time 2. During measure time 2, vibrations of pattern 3, the same as those in measure time 1, are output again. By repeating these vibration patterns 3, the driver can perceive the vibrations via the sense of touch and the synchronized part of music through his ears during beat times (1), (2), and (3) of measure time 1 of the part of music, and during the subsequent beat time (4), he can recognize that although he perceives the part of music through his ears, there is no vibration through his ears. By repeating these vibration patterns, the driver can determine that the vehicle speed is in the third speed range, that is, within a speed range of 30 to 40 (Km / h).

[0020] By outputting the music parts into the vehicle and controlling the generation of vibrations corresponding to the number of steps in each speed range, the driver can understand up to which beat (which is also the beat time) in each measure there is vibration synchronized with the sound of the musical notes, and thus can quantitatively grasp the number of steps in the speed range corresponding to the vehicle's speed, and this understanding can be understood at any time while driving. [Example]

[0021] In the explanation up to this point, the speed range steps have been explained using decimal numbers, but in the explanation that follows, we will explain the speed range steps using an example where a two-digit quaternary number is used, using four types of numbers (bases) from 0 to 3. The horizontal and vertical axes in Figure 4 are basically the same as those in Figure 3, but there are the following differences. First, in Figure 3, the number of stages ranged from 0 to 4, but in Figure 4, the number of stages is shown as a two-digit quaternary number ranging from 00 to 21. In addition, from the third row onwards in the third column from the left on the vertical axis, a distinction is made between the right hand side and the left hand side to distinguish between the left and right vibration parts 18 of the handle 17 that generate vibration, with the vibration on the left hand side indicating the first digit in a base-4 number system and the vibration on the right hand side indicating the second digit in a base-4 number system. Although this display should also indicate the vibration amount of the vibrating unit 18, it has been simplified to simply indicate "vibration" in order to avoid making Figure 4 too complicated. Furthermore, although the measure times in the top row are presented up to the fourth measure time, it is assumed that there may actually be more measures beyond that. In addition, the vibration on the left hand side, which indicates the first digit of the speed range in a base 4 system, is output controlled to transmit to the driver a vibration with the same waveform as the part of the music being used, or a vibration with a similar waveform. Furthermore, the vibrations on the right hand side, which indicate the second digit of the tempo range in base 4, are automatically generated based on the performance information in the music being used, and are a new part dedicated to the right hand, using metronome sounds and rhythmic sounds that repeat every measure. It is designed to be superimposed on the left-hand part of the music that is output inside the car. At the same time, a vibration waveform identical to or synchronized with the vibration waveform of the right-hand part is output from the right-hand vibration section 18 and transmitted to the driver. However, if the number of pieces to be used for the left hand side is sufficient compared to the number of sound sources or part pieces required for the first digit of the quaternary system, it is also possible to use unused sound sources or part pieces to output the vibrations of the second digit.

[0022] Next, an example of the operation of the sound velocity meter of the present invention will be described with reference to FIG. The vibration outputs from step number 00 to step number 03 in the speed range in the left column of Fig. 4 appear to be the same as the speed range from step number 0 to step number 3 in Fig. 3. However, these vibration outputs are generated only by the left-hand side vibration unit 18, and the vibrations of the left-hand side vibration unit 18 indicate the first digit after converting a decimal number to a quaternary number. The vibration part 18 on the right hand side vibrates to indicate the second digit of the number after converting the decimal number into a quaternary number. For this reason, for speed range stages 00 to 03, there will be no vibration output from the right hand when the second digit of the quaternary number is 0. In this case, the vibration output from stages 0 to 3 on the left hand side will be the same as pattern 0, pattern 1, pattern 2, and pattern 3 in Figure 3, respectively. These four vibration patterns on the left hand side will be repeated every time the quaternary number is carried over in the subsequent speed ranges. When the vehicle speed increases further and the speed range reaches the 10th stage, the second digit of the quaternary stage number changes to 1, causing a vibration at beat time (1) on the right hand side, and the vibration at beat time (1) continues with each new measure. It can be seen that this vibration causes the stage number to increase. This vibration of the right hand continues up to the 13th step in the speed range, with the second digit continuing to indicate 1. This, combined with the same vibrations as pattern 0, pattern 1, pattern 2, and pattern 3, which indicate the first digit on the left hand side, allows the driver to distinguish between the 13 steps of the speed range. If you accelerate further and reach the 20th level of the speed range, the vibrations on the right hand side occur at beat times (1) and (2). This continues up to the 23rd speed range, with the second digit continuing to indicate 2. This, combined with the same vibrations as pattern 0, pattern 1, pattern 2, and pattern 3, which indicate the first digit on the left hand side, allows the driver to distinguish between the 23 steps of the speed range. However, Figure 4 shows only up to stage 21, and stages 22 and 23 are omitted. Similarly, for speed range step numbers 30 to 33, the vibrations on the right hand side occur at beat times (1), (2), and (3), continuing up to the 33rd step of the speed range, and the same vibration combinations as pattern 0, pattern 1, pattern 2, and pattern 3, which indicate the first digit on the left hand side, allow the driver to distinguish the steps of the speed range up to the 33rd step. However, some of these are not shown in Figure 4. In this way, by distinguishing between vibration generation on the right and left hand sides of the speed range, the driver can understand the number of speed steps up to 33 steps in base 4 (15 steps in decimal).

[0023] Here, if each speed range is divided into steps of 10 km / h, for example, a speed range up to 150 km / h can be displayed using a two-digit quaternary number. Furthermore, a sonic speedometer can be realized that can also display a vehicle speed range above 150 km / h. Therefore, the present invention can be fully used as a practical product. In addition, in the beat time within the measure (4), no vibration is output, but the periodic existence of this beat time without vibration has the effect of making the measure divisions easier to understand.

[0024] This method of recognizing these speed range stages as numbers may seem complicated at first glance, but it is a similar method of recognizing numbers to how an abacus user can immediately determine numbers from 0 to 9 by distinguishing between four 1-beads and one 5-bead on a four-bead abacus.Compared to simply lining up nine 1-beads to represent numbers from 0 to 9, this method has the advantage of being easier to see and distinguish between numbers; the same effect is also seen in the use of two-digit quaternary numbers, which are easier to distinguish than decimal numbers.

[0025] This vibration output is similar to pulse width modulation, which changes the duty ratio in transmission technology, and the vibration output time, which is measured in beat time units, with one measure being one pulse, can be considered the ON state in the duty ratio of pulse width modulation. However, while the output of pulse width modulation in the ON state is a constant value, the major difference is that the vibration output of this invention is a vibration waveform that is the same as or synchronized with the part of the music output inside the car. Furthermore, the steering wheel 17 in a moving vehicle is subject to a mixture of vibration noise caused by the vehicle's movement, vibrations from the left-hand part and the right-hand part, etc., and inside the vehicle there is output sound from a music piece consisting of multiple parts, to which the noise caused by the vehicle's movement is added. From these, it is necessary to select the desired part indicated by the vibration and the beat time within it. To aid in this selection, the auditory information of a specific part of music is synchronized with vibrations based on the same signal waveform as that part of music, and by matching these auditory and tactile vibrations, bar times and beat times can be identified, which is another feature of the present invention. [Example]

[0026] Next, Fig. 5 shows an example of a flowchart of a program that generates vibrations in the left and right handles in the sound velocity meter shown in Fig. 4. It should be noted that this flowchart is based on the premise that the vehicle speed is divided into a plurality of speed ranges and that the speed ranges are represented by quaternary numbers starting from 00.

[0027] The program starts at 101. In process 102, the sound velocity meter is activated and the musical score and sound source to be used in the car are selected. In process 103, a part in the musical score to be used for vibrating the left hand side of the steering wheel is selected, and performance information shown in the musical score is acquired. In process 104, a musical part for vibration of the right hand side of the handle is automatically generated based on the performance information shown in the musical score. It should be noted that if there is an unused part music piece in process 103, that part music piece can be used as the part music piece to be used here, and in that case, there is no need to generate a part music piece. In process 105, the bar time width Tm and the beat time width Tb are calculated from the musical score of the music piece, and the respective times are determined. In process 106, the music according to the score starts to be output as auditory information inside the vehicle. In process 107, the elapsed time is set to T=0 and the clock operation is started. In process 108, the number of stages of the speed range to which the current vehicle speed obtained from the speed detection unit 5 belongs is set in S as a two-digit quaternary number. In process 109, the first digit of the number of stages set in S is set in S1, and the second digit is set in S2. In decision 110, we determine whether S is greater than or equal to 0 (zero). If the answer to decision 110 is negative (no), the process moves to step 111. In process 111, the vibration for the entire beat time is set to 0 (zero), the vehicle is stopped, and the sonic speed meter is set to the initial state. Then, the process proceeds to decision 140. If decision 110 is affirmative (yes), proceed to decision 120. In decision 120, it is determined whether S1, the first digit of S, is equal to or greater than 0. If the answer to decision 120 is affirmative (YES), the process moves to step 121. In process 121, the elapsed time T required by program (L) 122 and the value S1 of the first digit of the number of stages S are set in TC and T1, respectively, and the process moves to decision 130. Here, program (L) 122 is a program (L) that outputs vibrations to the vibration unit 18 on the left hand side of the handle 17, and when the elapsed time TC is within the range from time 0 (zero) to the time obtained by multiplying the first digit value T1 of the stage number by the beat time width Tb, the vibration unit 18 on the left hand side of the handle 17 has the role of outputting vibrations that are the same as or similar to the part song selected in process 103. If decision 120 is negative (no), then proceed to decision 130 . In decision 130, it is determined whether S2, the second digit of S, is equal to or greater than 0. If decision 130 is affirmative (yes), proceed to 131. In 131, the elapsed time T and the second digit value S2 of the number of stages S required by the program (R) 132 are set in TC and T2, respectively, and the process proceeds to 140. Here, program (R) 132 is a program (R) that outputs vibrations to the vibration unit 18 on the right hand side of the handle 17, and when the elapsed time TC is within the range from time 0 (zero) to the time obtained by multiplying the second digit value T2 of the stage number by the beat time width Tb, the vibration unit 18 on the right hand side of the handle 17 has the role of outputting vibrations that are the same as or similar to the part music generated in process 104. If decision 130 is negative (no), then proceed to decision 140 . Decision 140 determines whether to stop the sound velocity meter. If decision 140 is affirmative (YES), the program moves to step 141 and stops. If decision 140 is negative (no), then decision 150 is reached. Decision 150 determines whether the elapsed time T is equal to or greater than Tm. If the answer to decision 150 is affirmative (YES), the process moves to step 151, where the elapsed time T is reset to 0, and the process moves to step 108. If decision 150 is negative, the process moves to step 108. The above operations are performed.

[0028] By using this flowchart, it is possible to output vibrations to the steering wheel or seats that are synchronized with a specific part of the music being played in the car, similar to the "vibration output time for speed range" shown in Figure 4. Up to this point, the explanation has been given mainly assuming that the number of stages S of the speed range corresponding to the vehicle speed is a quaternary number system; however, the positional radix system can be applied to systems other than quaternary, and at least if the number of stages in the positional radix system is decimal or less, it becomes possible to reduce the number of types of sound sources and musical parts required compared to decimal systems. Furthermore, it is possible to reduce the pre-learning required for the driver to determine the stages of the speed range, and the burden of making such judgments, and there is an advantage in that the range of musical pieces to be selected, such as solo pieces and ensembles, that can be used is wider. In particular, if a metronome sound or rhythmic sound can be independently generated and superimposed on audio information being output in the car, audio information that cannot be considered music, such as radio broadcasts, can be used in the present invention. For this reason, radio broadcasts can also be considered a type of background music (music).

[0029] Furthermore, up to this point, we have assumed that repetitions occur in measure units within the musical score, but in fast or complex tempos, it can be difficult for musical novices to understand the divisions of measures and beats. In such cases, it is possible to change a unit that combines several measures into a new repetition unit, and furthermore, to use the individual measure times instead of beat times. Furthermore, it is also possible to reset the beat times to a different value from that specified in the original musical score, to an easier-to-understand repetition unit time. When using such a new tempo, the bar time T0 and note duration t0 will be changed to unique values ​​on the sound velocity meter. Furthermore, rests 34 and 35 shown in Figure 2 are periods when there is essentially no output from the sound source, and therefore do not produce vibrations. However, the sound velocity meter has the advantage of being able to identify the presence of rests and identify individual beats. Therefore, since most conventional instruments have waveforms with a lingering sound, it is possible to deliberately generate vibrations to indicate the presence of a rest by using a signal that does not have a lingering sound, such as a square wave. By changing the method of using the musical score and the timing of vibration generation, it becomes possible to reduce the restrictions on the selection of music when a person with little musical knowledge uses a sound velocity meter. Furthermore, this sound velocity meter allows the music output in the vehicle to be tailored to the driver's preferences, which has the advantage of making it possible to maintain a desirable sound environment in the vehicle compared to sound velocity meter outputs that are limited to beeps or special music set specifically for the sound velocity meter. [Example]

[0030] Next, an example of a sonic speedometer that indicates speeding violations (also called "speeding violations") will be described in turn using (FIG. 6), (FIG. 7), and (FIG. 8). FIG. 6 shows the relationship between vehicle speed and volume of music, etc., and it is assumed here that the music to be used is an ensemble consisting of at least four pieces, from part 41 to part 44. In Figure 6, the horizontal axis represents the vehicle speed, and the vertical axis represents the volume of the music or other sound output inside the vehicle. In this sound speed meter, the volume of the part 41 increases as the speed increases within the speed range of 0 to S1, saturates appropriately as the speed increases further, and maintains the volume at any speed above that, as shown by the solid line in the figure. As the vehicle speed increases, part 42 shown by the dashed line is output at speeds S1 and above. Similarly, part 43 shown by the dashed line is output from speeds S2 and S3, and part 44 shown by the long dashed line is output continuously, just like output 41. As a result, only the music of part 41 is output in the car in the speed range 51 between speed 0 and S1. In a speed range 52 between speeds S1 and S2, part 41 and part 42 are superimposed and output to the inside of the vehicle. In the speed range 53 between speeds S2 and S3, part 41, part 42, and part 43 are superimposed and output to the inside of the car. In a speed range 54 above speed S3, part music 41, part music 42, part music 43 and part music 44 are superimposed and output to the inside of the vehicle.

[0031] The music used here is, for example: Part 41 outputs the sound source as a cymbal, Part 42 outputs the sound source as a saxophone, Part 43 outputs the sound source as a vibraphone, Part 44 is output based on the sound source. Furthermore, each of these sound sources will output the part of the same ensemble piece that each sound source is responsible for. The speed range of 51 outputs a cymbal-only part, The speed range 52 outputs an ensemble consisting of cymbal and saxophone parts, The speed range 53 outputs an ensemble consisting of cymbal, saxophone and vibraphone parts. In the speed range 54, an ensemble consisting of parts for cymbals, saxophone, vibraphone, and bass is output. By doing this, the driver can always determine how many types of instruments (sound sources) are being output.

[0032] The driver understands in advance that the number of types of superimposed sound sources corresponds to the number of stages in the speed range indicating the vehicle speed, and from that number, the driver can quantitatively understand the number of stages in the speed range in which the vehicle is traveling, and at all times while driving. This makes it possible to easily and constantly determine the speed range in which the vehicle is traveling using only hearing. For this reason, there has been a proposal to apply this function to the speed range of fines and violation points imposed for speeding, and to use it as a sonic speedometer for speeding violation warnings. This sound speed meter can use each part of an ensemble consisting of four types of sound sources, 41 to 44 in Figure 6, so it can present speeds with a more musical quality than a simple beep or other warning, and has the advantage of maintaining a natural atmosphere inside the car. However, to be able to distinguish between four or more speed ranges, the instrument must be composed of four or more sound sources or parts. Therefore, if a sound speed meter is made up of more speed ranges, the number of sound sources and parts must increase accordingly, which places a greater restriction on the music that can be used, and requires musical talent to be able to distinguish between each sound source and part. This places a limit on how many speed ranges can be made. [Example]

[0033] Next, FIG. 7 will be described. The sound velocity meter using Figure 7 is a sound velocity meter that adds the vibration function of the sound velocity meter explained in Figure 4 to the sound velocity meter explained in Figure 6, and although it requires some learning, it is a sound velocity meter that can grasp a multi-stage velocity range. Figure 7 is a diagram that combines the time axes (horizontal axes) of the two types of figures, Figure 4 and Figure 6, by conditioning them to make them common for the purpose of explanation. Therefore, it is important to understand in advance that the relationship between vehicle speed and time in this diagram is valid only under certain conditions. Specifically, Figure 7 is valid only when the vehicle passes through each stage of the speed range in one measure of time and moves on to the next speed range. Therefore, for example, in Figure 7, if it takes two measure times for the vehicle speed to reach speed S1 and exceed speed S2, it will be necessary to add measure time 2 and another set of the same measure time 2, but this figure assumes that such a situation will not occur.

[0034] Further, the description of FIG. 7 will be continued. In Figure 7, the speed range is newly shown as a two-digit ternary number. Note that although the normal ternary number system starts with 00, in this case the speed range determined by the sonic velocity meter in Figure 6 has been added to the first half, so the 00A and 00B stages are shown before 00. Also, the speeds in the line below (0 to S9) do not normally fit into the time axis, but as mentioned above, for the sake of explanation, we have applied this to a special case in which the speed increases linearly, one step at a time, from speed 0 to speed S9 for each measure of measure time (10 to 9). The top row of Figure 7 shows three different sound sources or parts 41, 42, and 43, as explained in Figure 6. This output allows the driver to know the composition of the sound sources used in each speed range up to speed S3, and also allows the driver to understand the speed range unit step from the number of sound sources and parts superimposed on the vehicle speed up to S3. These step numbers are shown in ternary notation as 00A, 00B, and 00. Here, the step numbers in the range from speed 0 (zero) to speed S2 are subscripted with A and B to distinguish them from the others. However, the 00 notation for the third step is intentionally refrained from notating it as 00C because it is the same as the first step of the sound speed meter that also uses vibration as shown below. When the speed is S3 or higher, music parts from three types of sound sources are constantly output inside the vehicle. Vibrations with the same signal as the selected music part are output from vibration units 18 on the left and right sides of the steering wheel 17 and vibration unit 20 on the seat 19, allowing the driver to understand the speed range stages and warnings. The patterns of each vibration are shown in the vibration section in the second row from the bottom, in the same way as in Figure 4. However, because the speed range stages here are expressed in ternary notation, the distinction between values ​​0, 1, and 2 for each digit is simplified so that they are output only based on the presence or absence of vibration in beat times 1 and 2. However, the relationship between vibration and beat time in the present invention is not limited to this, and it is also possible to distinguish between values ​​1 and 2 using a vibration pattern that combines beat times 1 and 3, or to make a vibration pattern of double the time by consecutively connecting beat times 1 and 2, and then connecting beat times 3 and 4, and so on.

[0035] Furthermore, the speed range step number 00 or more in FIG. 7 will be described. At stage number 00, all three types of part music 41, part music 42, and part music 43 are output as superimposed part music, so it is necessary to clarify the part music synchronized with the vibration of the left hand side and the right hand side. Therefore, for example, part 41 is for the left hand side, part 42 is for the seat vibration section 2, and part 43 is for the right hand side, and each stage of the speed range will be explained.

[0036] In FIG. 7, at bar time 3 at speed S2 or above, the number of steps in the speed range is 00, and the value of the left hand side indicated by the first digit of the ternary number and the value of the right hand side indicated by the second digit are both 0 (zero). Therefore, in measure time 3, neither the left hand nor the right hand generates vibrations on any beat. This allows the driver to determine that the vehicle is traveling within the 00 stage of the speed range.

[0037] When the vehicle accelerates and enters the speed range of measure time 4, the step number is ternary 01, the first digit is 1 and the second digit is 0, so the left hand side representing the first digit outputs vibration only at beat time 1. The right hand side representing the second digit is 0, so it does not output vibration at any beat. The presence or absence of these vibrations is shown in the vibration item column at the bottom of FIG. 7 as a series of vertical lines (left hand side) and a series of horizontal lines (right hand side) indicating output timing. Furthermore, the vibration waveform at beat time 1 on the left hand side, which indicates the first digit, is the same as or synchronized with the output waveform of part 41, so that the auditory information from part 41 in the music output in the car matches the tactile information from the vibration on the left hand side. This makes it possible to select the vibration on the left hand side and the part 41 in the music, or to select the sound source, and also to determine the presence of a note (sound produced by the sound source) within the beat time in the part music specified by the vibration. This note reveals the beat time specified by the vibration. Similarly, the right hand side is designed so that the auditory information from the part 43 matches the tactile information from the vibration on the right hand side. This allows the right hand side vibration to be selected from the part 43 in the music, or the sound source to be selected, and it also makes it possible to determine the note (sound produced by the sound source) within the beat time in the part music specified by the vibration, and the beat time specified by the vibration becomes clear. With these functions, at measure time 4, the right hand side does not have the seismic intensity to synchronize with the output part 42, The vibration of the part 41 of the sound source and the left hand side are synchronized, and from the number of beats that accompany the vibration within each measure time in the part 41, it can be seen that the value of the first digit of the vehicle speed range step is 1. As explained earlier, since there is no output for the left hand vibration at each measure, the driver can determine that the vehicle is traveling at the 01 speed range because the second digit of the speed range step is 0.

[0038] When the vehicle accelerates further and enters the speed range of measure time 5, the step number is ternary 02, with the first digit being 2 and the second digit being 0. Therefore, the left hand side indicating the first digit outputs vibrations at beat times 1 and 2. The right hand side indicating the second digit is 0, so it does not output vibrations at any beat. These vibrations are repeated within each measure time, and the driver can determine that the vehicle is traveling at the 02 stage of the speed range.

[0039] When the vehicle accelerates further and enters the speed range of measure time 6, the step number is 10 in ternary, the first digit is 0 and the second digit is 1, so the left hand side representing the first digit does not output vibration for the entire beat time. The right hand side representing the second digit is 1, so it outputs vibration at beat time 1. By feeling this vibration with each repetition of the bar, the driver can determine that the vehicle is traveling at one of the 10 speed ranges. In this way, the driver can distinguish between left and right hand vibrations and understand the vehicle speed as a range of speeds. This may seem complicated at first glance, but in reality, the driver will feel it as follows:

[0040] The specific sensations experienced by the driver through these series of events will now be explained. Here, it is assumed that the vehicle speed increases linearly, and the output of music into the vehicle and the vibrations felt by the left and right hands gripping the steering wheel will be explained using the speed range steps in Figure 7 as units. At speed range step 00A, part 41 begins to play. At the speed range step 00B, part 42 begins to be heard overlapping. At speed range step 00, part 43 begins to be heard overlapping further. By superimposing these parts, the driver can judge the number of steps in each stage. At this stage, there is no vibration in the left or right hand synchronized with the music.

[0041] Furthermore, when the vehicle speed increases to stage 01 or higher, Vibrations synchronized with the output signal of part 41 are generated on the left hand side in units of beat time. Vibrations synchronized with the output signal of part 43 are generated on the right hand side in units of beat time.

[0042] For three speed range stages, from stage 00 to stage 02, the first digit of the stage number is written on the left hand side. At measure time 3, there is no vibration (equivalent to 0). At measure time 4, there is vibration at beat time 1 (corresponding to 1), In measure time 5, there is vibration in beat time 1 and beat time 2 (corresponding to 2), This results in a three-state output. These repetitive vibrations on the left hand side will occur repeatedly as the vehicle accelerates thereafter.

[0043] On the other hand, the vibration on the right hand side, which is the second digit of the step number, is In the three speed range stages 00 to 02, there is no vibration. In the three stages of the speed range from stage 10 to stage 12, there is vibration in beat time 1. In the three stages of the speed range from stage 20 to stage 22, there is vibration in beat time 1 and beat time 2. In this way, the number of stages in the speed range can be understood as a "group" of about three types. [Example]

[0044] In normal vehicle operation, drivers are not required to be constantly aware of their vehicle speed in most cases, but vehicle speed plays an important role mainly when speeding violations (so-called speeding violations) occur. There are two types of penalty for speeding violations: fines and penalty points. Speeding between 1 and 19 km / h is 1 point, 20 to 24 km / h is 2 points, 25 to 29 km / h is 3 points, 30 to 49 km / h is 6 points, and 50 km / h or more is 12 points. Speeding over 6 points is punishable by imprisonment and fines. Therefore, it can be considered a criminal act. (From the Tokyo Metropolitan Police Department Traffic Violation Points Table) An example of a sound speedometer corresponding to the violation speed is explained in Figure 8. Figure 8 is basically the same as Figure 7, but the details will be explained below according to the item names on the left side.

[0045] The top row of Figure 8 shows the volume of each of the parts 41, 42, and 43 used versus time on the horizontal axis. These parts are sound outputs consisting of the same signals as the left-hand, seat, and right-hand parts described below. Specifically, part 41 is for the left-hand side, part 42 is for the seat, and part 43 is for the right-hand side. The speed after 0 (zero) is speed S, and then speeds Sn0 to Sn6 are shown. The speed S is a description that indicates the intermediate stage before speeding and does not have any deeper meaning. Sn0 is a speed range that acts as a warning to indicate that the vehicle is approaching a speed limit set, for example, 5 km / h slower than the speed limit Sn1. Here, vibration occurs in the seat and part 42 is output, both of which indicate that the vehicle has entered the speed range that displays a "warning." The speed Sn1 is the speed limit of each road, and varies depending on the road. This speed limit is determined based on the vehicle's location information using GPS, the road information based on map information, and the speed limit information set for each road. At speeds above Sn1, the output of the part 42 begins, indicating that the vehicle has entered the speed violation stage, and the number of speed violation stages and violation points can be determined through vibrations synchronized with the part 42. In Figure 8, the speed range stages are shown as violation points converted into a ternary number. These stages are numbered ternarily as 00, 01, 02, 10, 12, and 20. These numbers correspond to 1, 2, 3, 6, and 12 in decimal notation, respectively, and indicate the violation points. These violation points are discrete numbers, but for ease of explanation, they have been converted into ternary numbers. The bar time and beat time are the same as in Figure 7, but the maximum bar time is limited to 8. In addition to the vibrations on the right and left hand sides shown in FIG. 7, vibrations from the vibrating portion 20 of the seat 19 in FIG. 1 are newly added.

[0046] Next, the operation will be specifically described. In the speeding violation points section, there is no mention of violation points for time periods 1 and 2. The word "warning" is used to indicate that the speed is close to the speed limit at measure time 3. Seat vibration is basically output at beat time 1 of each repeated measure. However, at measure time 1 and measure time 2, there is no vibration on the seat, left hand side, or right hand side, and it can be seen that there are no violation points (0 points). In this example, there are two types of seat vibrations: those occurring above the speed limit and those occurring below the speed limit. The seat vibrations that start at speed Sn0 clearly indicate that the vehicle is approaching the speed limit. This warning seat vibration occurs repeatedly at beat time 1, and serves to alert the driver that they are speeding or approaching a speed limit, while also indicating beat time 1 of the repeated measure. The speeding violation points at the bottom of Figure 8 are a newly added item, and the specific speeding violation points are shown in decimal.

[0047] Next, the operation of the speed range in which the speed range stage is 01 or higher and is subject to speeding violations will be described. In the graph at the top showing the relationship between volume and speed, part 41 starts to be output at a vehicle speed of 0 (zero). This part 41 is a sound output that simply indicates that the sound velocity meter of the present invention is operating, and also serves as a signal source for the synchronized sound output required to generate vibrations on the left hand side.

[0048] In the speed range stage 01, the part 43 is output in such a way that the part 41 and the part 42 are superimposed on each other. This also allows the driver to understand through his / her hearing that the vehicle speed has reached the speed range of the speed violation. In addition, there is a vibration output on the left hand side at beat time 1 in measure time 4, and there is no vibration on the right hand side. Therefore, it can be understood that the speed range stage is 01 and the violation score is 1 point. In speed range stage 02, The left hand has vibration output at beat times 1 and 2 in measure time 5, while the right hand has no vibration. Therefore, it can be seen that the speed range is 02 and the violation score is 2 points. At speed range stage 10, there is no vibration on the left hand side, On the right hand side there is a vibration output at beat time 1 in measure time 6. Therefore, it can be seen that the speed range is 10 and the violation points are 3. In speed range step 20, There is no vibration on the left hand side, and there is vibration output on the right hand side at beat times 1 and 2 within measure time 7. Therefore, it can be seen that the speed range is 20 and the violation points are 6. In the speed range step 40, the step number shown in the original ternary number system is 110, but in a two-digit ternary number system, a carry cannot be made to the third digit. Therefore, when a restriction arises that prevents this carryover, by taking advantage of the fact that there are four beats in a measure, the second digit can be simply displayed in base 5, allowing for an irregularity, so that the decimal number 12 can be converted to the irregular ternary number 40. As a result, there is no vibration on the left hand side, and vibration output on the right hand side at beat times 1, 2, 3, and 4 within measure time 8. This allows the driver to understand that the speed limit is 40 and that the penalty points are 12. For reference, there is no vibration on the left hand side, and on the right hand side there is vibration output at beat times 1, 2, and 3 of measure time 8, but there is no vibration at beat time 4.The irregular ternary number 30 corresponds to the decimal number 9.

[0049] By adopting this numerical notation with a ternary carry restriction, the "sonic speedometer corresponding to violation speed" of the present invention allows the driver to always understand the violation points by the following simple vibration pattern. When the speed range is set to 01 or 02 (scores of 1 and 2), only the left-hand side of the steering wheel vibrates. Conversely, when the speed range is from 10 to 40 (scores of 3, 6, and 12), only the right-hand handle vibrates. When the vibration on the left hand side changes to the right hand side, the violation points can be understood to have reached three points. Furthermore, the violation points from then on will all change to vibrations on the right hand side, and the beat time will change by two times to 1, 2, 4, etc. Understanding these characteristics has the advantage of making it possible to easily and conveniently determine the violation points of a traveling vehicle at any time.

[0050] In this way, the sound speed meter of the present invention can measure the number of steps in the speed range for a piece of music, etc. By using a positional radix system with a smaller base than decimal numbers, the number of speed range stages can be expressed with a smaller base, and the number of speed range stages can be shown to the driver in terms of the length of time in units of beats within a measure.Furthermore, by making the speed range width variable, a speedometer can be realized that can auditorily present speeding violation stages set to an irregular speed range width. Furthermore, the present invention requires fewer musical sound sources and fewer musical parts, and by using, for example, two-digit ternary numbers, it is possible to easily show an eight-stage tempo range. If more steps are required, the first digit can remain ternary and the second digit can be treated as a quaternary or quinary number, which has the advantage of allowing the speed range to be expanded to include more steps. Furthermore, as shown in Figure 8, by using three types of vibrations, namely vibration units 18 on the right and left hand sides and vibration unit 20 on the driver's seat, and further by using three-digit ternary or quaternary numbers, it becomes possible to present a step-by-step speed range with a significantly expanded number of steps. [Example]

[0051] The explanation so far has focused on the combined use of in-car output of music and vibrations generated by the vibration unit 18 provided on the steering wheel 17 of the vehicle, but it is possible to substitute other functions for the role shared by vibrations. Specifically, this can be achieved by using light or sound information superimposed on music. A specific example of the use of light will be described below.

[0052] In the previous section (Example 4) using Figure 4, in the explanation below in paragraph (0022), the number of speed range stages was explained using an example of a two-digit quaternary number using four types of numbers (bases) from 0 to 3. In this description, "vibration on the left hand side" and "vibration on the right hand side" are replaced with, for example, "emission of blue light" and "emission of red light," respectively, and "vibration" and "vibrating unit" are replaced with "light" and "emission unit," respectively. Furthermore, an example was tried in which the light-emitting unit is not installed on the "steering wheel 17," but rather in an "appropriate, easily visible location." While detailed explanations will be omitted here to avoid redundant information, this example has the drawback of not necessarily achieving the characteristic of other examples, "eliminating periods of inattention to the road ahead," because it utilizes both hearing and vision. However, this speedometer retains the advantages and effects of the sonic speedometer described above, and also has the advantage of being able to supplement or replace conventional speedometers.

[0053] While the explanation so far has primarily focused on binary, ternary, and quaternary notation for speed range steps, other positional bases may be used depending on the number of steps required and the convenience of the driver. Furthermore, while the explanation has been given assuming that the values ​​of these bases are expressed numerically in accordance with the order of the beats in a measure on the musical score, it is possible to improve recognition by expressing each value numerically using two consecutive beats as the basic unit, or every other beat as the unit, in consideration of ease of perception and memorization. Furthermore, for music with a particularly fast tempo, it is also possible to use a numerical representation that converts the base using measure time instead of beat time as the unit. Furthermore, the relationship between measures and beats has been explained assuming a 4 / 4 time signature, but this can also be freely set to 4 / 8, 3 / 4, 3 / 2, or other relationships seen in minuets and waltzes. Furthermore, the time width of all measures used does not need to be constant; by making it variable, it has the advantage of being more flexible and can be adapted to modern music with complex tempos. In addition, the explanation has been given on the assumption that the musical part that generates the signal to synchronize the vibration is based on the music written as notes on the score and the performance information on the score, but it is also possible to automatically generate synchronized sounds or rhythm sounds that are compatible with the music and use them as the basis for the vibration. [Industrial Applicability]

[0054] In addition to the speedometers installed in ordinary vehicles, by installing the sonic speedometer of the present invention, which has a vibration generating unit (vibration unit), on the steering wheel, seat, or the like that the driver of the vehicle is always in contact with, it can be used as a sonic speedometer that always displays the speed range corresponding to the vehicle speed using music that is output and enjoyed inside the vehicle.Furthermore, specifically, it can be used as a sonic speedometer that can always recognize the level of violation when driving while speeding.
