Description

  The present invention relates to a vehicle alarm sound setting method and an alarm device.

  In vehicles, for example, automobiles, a large number of warnings using warning sounds are provided. For example, forgetting to turn off the light that works when you forget to turn off the headlight, or forgetting to turn off the light, forgetting to turn off the key when you open the door with the key inserted into the key cylinder, or the vehicle speed exceeds the specified vehicle speed There are a great number of types of alarms that are generated by alarm sounds, such as a vehicle speed over alarm that is activated when the vehicle travels, a reverse alarm that operates when traveling backwards, and a collision prediction alarm that is activated when a collision is predicted. In order to make it easy to identify the content to be alarmed as much as possible, the alarm sound blowing pattern is set to be as different as possible.

As described above, when the types of alarm contents to be alarmed increase, it becomes difficult to clearly recognize the alarm sound corresponding to the alarm contents. In particular, since the frequency used as an alarm sound is limited to a narrow frequency band of, for example, a range of 1 KHZ to 4 KHZ, it is virtually impossible to identify the alarm sound only by changing the frequency. . In Patent Document 1, in order to improve the distinguishability of a plurality of alarm sounds, a single tone of a different average rate scale or a complex tone different from the single tone is assigned to each alarm sound, It is disclosed that the period and number of alarm sounds are changed accordingly.
JP 2001-209871 A

  By the way, among a large number of alarm sounds, the alarm level indicating the importance or the like varies depending on the alarm purpose or the like. If it is possible to set an alarm sound according to the warning level according to the importance of the alarm among such a large number of alarm sounds, it is preferable for the passenger to clearly understand the meaning of the alarm sound. In addition, it is also preferable for enhancing the alerting effect for the occupant. In particular, since the use band of the frequency that greatly affects the alerting effect is narrow, it is preferable that a plurality of alarm sounds that effectively use the narrow band frequency can be easily set.

  On the other hand, when the number of types of alarms increases, it becomes difficult to avoid a situation in which a plurality of alarm sounds must be operated at the same operation timing. In this case, the passengers feel a little uncomfortable due to the dissonance between multiple alarm sounds, or it is difficult to clearly identify the content of the alarm and the important alarm sound is not noticed. Occurrence is also considered.

The present invention has been made in view of the above circumstances, and a first object of the present invention is to effectively use a narrow band of frequencies, and to provide a plurality of warning sounds that can be easily understood. An object of the present invention is to provide a vehicle alarm sound setting method that can be easily set.
A second object of the present invention is to provide an alarm device for a vehicle that prevents the passenger from feeling uncomfortable even when a plurality of alarm sounds are activated.
Furthermore, a third object of the present invention is to provide a vehicle alarm device that allows a passenger to clearly recognize a highly important alarm sound when a plurality of alarm sounds are activated.

In order to achieve the first object, the following first solution is adopted in the present invention. That is, as described in claim 1 in the claims,

It is supposed to be equipped with. According to the second solution, an alarm sound that preferentially assigns frequencies and periods that have a large influence on the alerting effect can be set according to the warning level while obtaining the effect corresponding to claim 1. In addition, a blowing pattern that takes into account the blowing rate and the number of repetitions is set, so that the identification of a plurality of alarm sounds is extremely easy to understand, and the frequency and cycle are changed according to the warning level. Therefore, it is possible to easily set a plurality of alarm sounds that are extremely unified.

Is set as at least one of a range of .45 and a range of 1.86 to 1.89 (corresponding to claim 9). In this case, a specific value of the frequency ratio between the plurality of frequencies that should be avoided is provided.

In order to achieve the third object, the following solution is adopted in the present invention. That is, as described in claim 10 in the claims,
An alarm device for a vehicle that gives an alarm by an alarm sound,
An alarm timing determining means for determining that a plurality of alarm sounds are operated at the same operation timing;
When it is determined by the alarm timing determination means that a plurality of alarm sounds are operated at the same operation timing, only one alarm sound with the highest alarm level is selected and the selected alarm sound is selected. Alarm sound selection means to perform alarm only by,
It is equipped with. According to the above solution, when multiple alarm sounds are activated at the same time, only the alarm sound with the highest warning level is activated. Can be made. In addition, it is preferable to prevent discomfort caused by simultaneous activation of a plurality of alarm sounds, and to prevent a situation in which an alarm content is misidentified to an occupant.

According to the first aspect of the present invention, it is possible to easily set a plurality of alarm sounds in which the warning level of the alarm sound is easily understood by effectively using a narrow band frequency.
According to the seventh aspect of the invention, in addition to the effect corresponding to the first aspect, the frequency and the period are changed according to the warning level, so that there is a sense of unity, and the blowing rate and the number of repetitions It is possible to easily set a plurality of alarm sounds in consideration of the above.
According to the invention described in claim 8, it is possible to prevent the passenger from feeling uncomfortable even when a plurality of warning sounds are activated.
According to the invention described in claim 10, the occupant can clearly recognize the alarm sound having high importance even at the timing when the plurality of alarm sounds are activated.

  FIG. 1 shows an example of setting the warning level according to the alarm content. In FIG. 1, warning levels and importance levels are used as parameters, and each parameter is divided into three levels of low, medium, and high, and a total of 9 levels of warning levels K1 to K9 are set by combinations thereof. The partition having the highest warning level and the highest importance level is set to the warning level K1 having the highest warning level, and the zone having the lowest warning level and the lowest level is set to the warning level K9 having the lowest warning level. Thus, the warning level K5 is set such that a section having a middle level of warning and a middle level of importance has a middle level of the warning level. The warning level is K1, K2, K3, K4 in order from the highest to the lowest. The order is K5, K6, K7, K8, K9.

  The “high” alertness corresponds to a situation where the passenger is unconscious and in a dangerous situation or forgets to operate the passenger. “Middle” of the warning property corresponds to a situation that is linked to an operation that the occupant is aware of. “Low” warning is intended to prevent accidental operation by passengers, but also includes situations during normal operation. The “high” level of importance corresponds to a situation that may directly or indirectly cause damage to the human body, and also assumes the possibility of a collision or fire accident. The “medium” importance level assumes a situation in which each function has an abnormality, and the importance level increases when the function is notified for a long time. The importance level “low” corresponds to other situations other than those described above.

  The specific contents of the nine warning level levels set as described above may be as follows, for example. The warning level K1 is included, for example, when a collision is predicted or when a lane departs during auto-cruise control that also performs lane keeping control. The warning level K2 includes, for example, that the seat belt is not worn when starting. The warning level K3 includes, for example, vehicle speed over. The warning level K4 includes, for example, forgetting to return the parking brake or an abnormality in tire air pressure. What is included in the warning level K5 is, for example, pinching by PSD (power sliding door). The warning level K6 includes, for example, when traveling backward. The warning level K7 includes, for example, forgetting to turn off the light. The warning level K8 includes, for example, forgetting to remove the key (leaving the key in the vehicle). The warning level included in the embodiment is not set in the warning level K9.

  For each of the nine warning levels, a target warning index is set, for example, as shown in FIG. The warning level index is an index of the warning effect for passengers. The higher the warning level index, the greater the warning effect. The target warning level index is the warning level that should be set according to the warning content. Indicates the target value of the index. Specifically, the warning level K1 has a target warning level index set to 7 or higher, the warning level K2 and K3 have a target warning level index set to less than 6-7, and the warning level K4 and K5 have target warning levels. The degree index is set to less than 5-6, and the warning degree levels K6 to K9 are set to the target warning degree index less than 5.

  FIG. 3 to FIG. 6 are characteristic maps showing the correspondence between the above-described warning degree index and the warning sound component constituting the alarm sound blowing pattern. In the embodiment, the warning sound component includes frequency and There are four types: period, blowing rate, and number of repetitions. This characteristic map will be described individually. FIG. 3 shows a correspondence relationship between the frequency and the warning degree index. The higher the frequency, the higher the warning degree index. Note that a frequency band of 1 KHZ to 4 KHZ is used. FIG. 4 shows the correspondence between the period and the warning degree index. The shorter the period, the higher the warning degree index is set. FIG. 5 shows the correspondence between the number of repetitions and the warning degree index, and the warning degree index is set to increase as the number of repetitions increases. FIG. 6 shows the correspondence between the sounding rate and the warning degree index, and the warning degree index is set to increase as the blowing rate increases.

  Next, a procedure for finally setting a plurality of warning sounds individually based on the warning level, the target warning level index, and each characteristic map will be described with reference to FIG. First, since the contents shown in FIG. 1 are set, a warning level corresponding to the contents to be alarmed is selected from FIG. For example, when setting a warning sound for warning of collision prediction, the warning level K1 is selected from FIG. The frequency is then selected according to the selected warning level. When selecting a frequency, a value near 4 KHZ is selected for the warning level K1 to K3, and a value near 2 to 4 KHZ is selected for the warning level K4 and K5, and the warning level K6. A value in the vicinity of 2KHZ is selected for .about.K9. Note that the higher the warning level (closer to K1), the higher the selected frequency. The frequency selected as described above is collated with the characteristic map of FIG. 3, and the warning level index corresponding to the selected frequency is used for the calculation for satisfying the target warning level index as will be described later. Set as an exponent.

  After the frequency selection, the period is selected. That is, a cycle of 500 ms or less is selected for the warning level K1, and a cycle of 1 s or less (preferably 500 ms or more) is selected for the warning levels K2 and K3. For warning levels K4 and K5, when a frequency near 2 KHZ is selected, 500 ms or less is selected, and when a frequency near 4 KHZ is selected, a period of 1 s or more is selected. For the warning level K6 to K9, a period of 1 s or longer is selected. The period selected as described above is collated with the characteristic map of FIG. 4 and the warning degree index corresponding to the selected period is used for calculation for satisfying the target warning degree index as will be described later. Set as an exponent.

  The target warning degree index is the difference warning degree index obtained by subtracting the total value of the frequency warning degree index corresponding to the frequency selected as described above and the periodic warning degree index corresponding to the selected period from the target warning degree index. It becomes a shortage warning degree index that is insufficient to satisfy. This shortage warning degree index is set (complemented) by the blowing rate warning degree index corresponding to the blowing rate from FIG. 5 and the repetition number warning degree index corresponding to the repetition number from FIG. That is, when the warning content is, for example, a collision prediction, the target warning index corresponding to the warning level K1 is 7 or more. On the other hand, the frequency warning index obtained from FIG. 3 corresponding to the frequency (4KHZ) selected as described above is 3.2, and is a diagram corresponding to the cycle (500 ms or less) selected as described above. The periodic warning degree index obtained from 4 is 2.5, and the added value of both of the warning degree indices 3.2 and 2.5 is “5.7”. Since the target warning degree index corresponding to the collision prediction is “7 or more”, the insufficient warning degree index that is the difference between the target warning degree index of 7 or more and the added value “5.7” is “1.3 or more”. Therefore, the insufficient warning degree index is supplemented by the repetition number warning degree index obtained from the setting of the number of repetitions and the blowing rate warning degree index obtained from the setting of the blowing rate. For example, by selecting 2 as the number of repetitions, the repetition number warning degree index is “1.6” from FIG. 5, and by selecting 20% as the blowing rate, the blowing rate warning degree index “0.8” is can get. With respect to the added value of the frequency warning degree index “3.2” and the periodic warning degree index “2.5”, the above-mentioned repetition number warning degree index “1.6” and the sounding rate warning degree index “0. By adding “8”, the total value becomes “8.1”, and the condition of the target warning degree index 7 or more corresponding to the collision prediction is satisfied.

  As described above, the frequency, the period, the number of repetitions, and the sounding rate are set as the sounding sound components that make up the sounding pattern of the sounding sound that corresponds to the content of the warning (the warning level and the target warning index). (Selected) and an alarm sound is generated with the set sound pattern. Then, the following tuning is performed for the set alarm sounds. First, when there are a plurality of alarm sounds having the same operation timing, the frequency ratio is slightly changed so as not to generate a dissonance sound. Specifically, values obtained by dividing a high frequency by a low frequency indicating a frequency ratio are 1.06 to 1.08, 1.10 to 1.12, 1.43 to 1. It is made not to become the range of 45 and the range of 1.86-1.89. When the numerical value range that generates a dissonance is reached, at least one of the low frequency and the high frequency is slightly changed so that the numerical value range is not included. Although three or more alarm sounds may be activated simultaneously, in this case, any combination of two frequencies out of three or more frequencies is set so as not to fall within the above numerical range.

  Next, a specific example of the alarm sound blowing pattern set as described above will be described with reference to FIGS. First, FIG. 8 shows a setting example of an alarm sound for forgetting to remove a key. Forgetting to remove a key, the warning level is K8, and the target warning level index is less than 5. In this case, the alarm sound forgetting to remove the key is repeated twice (the warning index obtained from the characteristic map in FIG. 5 is 1.64), and the blowing rate is 35.2% (from the characteristic map in FIG. 6). The warning degree index obtained is 1.09), the period is 1250 ms (the warning degree index obtained from the characteristic map of FIG. 4 is 0.81), and the frequency is 1.8 KHZ (the warning obtained from the characteristic map of FIG. 3). The degree index is 0.64), and the total warning degree index is 4.2, which satisfies the target warning degree index of less than 5.

  FIG. 9 shows a setting example of an alarm sound for warning a lane departure, which is a lane departure warning level K1, and the target warning level index is 7 or more. In this case, the warning sound for departure from the lane is continuous without any restriction where the number of repetitions is 5 or more (its warning degree index obtained from the characteristic map of FIG. 5 is 2.88), and the blowing rate is 66.7%. (The warning degree index obtained from the characteristic map of FIG. 6 is 1.48), the period is 187.5 ms (the warning degree index obtained from the characteristic map of FIG. 4 is 3.92), and the frequency is 4.0 KHZ (FIG. The warning level index obtained from the characteristic map of 3 is 3.12), and the total warning level index is 11.4, which satisfies the target warning level index of 7 or more (particularly alerting) Since an extremely high effect is required, the warning degree index of the alarm sound actually set is extremely large).

  FIG. 10 shows an example of setting an alarm sound for forgetting to turn off the light. Forgetting to turn off the light, the warning level is K7, and the target warning level index is less than 5. In this case, the alarm sound forgetting to turn off the light is repeated once (the warning index obtained from the characteristic map in FIG. 5 is 0.88), and the blowing rate is 100% (that is obtained from the characteristic map in FIG. 6). Warning degree index is 1.94), there is no period (the warning degree index obtained from the characteristic map of FIG. 4 is 0), and the frequency is 1.9 KHZ (the warning degree index obtained from the characteristic map of FIG. 75), and the total warning degree index is 3.6, which satisfies the target warning degree index of less than 5.

  Here, when there is a possibility that one in-vehicle device, for example, an in-vehicle device related to brake control, will emit a plurality of warning sounds at the same time, the warning level is the highest of the plurality of warning sounds (the target warning degree index is large). ) It is possible to unify the alarm sound corresponding to the alarm content and set only one alarm sound.

  When it is time to activate multiple alarm sounds at the same time, the alarm level with the highest warning level among the multiple alarm sounds that are simultaneously activated is controlled by the control of the alarm controller installed in the vehicle (target warning index) It is also possible to control so that only the alarm sound corresponding to the alarm content is generated. In this case, it is not limited to the setting on the in-vehicle side (before factory shipment) in advance, but the timing at which a plurality of alarm sounds are simultaneously activated by post-processing by the controller for alarm sound generation mounted on the in-vehicle device. The alarm sound at the time of the alarm is unified into one alarm sound. Specifically, as shown in FIG. 11, the alarm sound generation controller U includes a plurality of in-vehicle devices 10A to 10D (in the embodiment, four in-vehicle devices are shown, but the number of in-vehicle devices is not limited). Is set to output an output signal corresponding to the blowing pattern to the speakers 11A to 11C that generate an alarm sound. The reason why a plurality of speakers are provided is to select a suitable speaker according to the frequency. That is, the speaker 11A is suitable for sounding alarm sound having a frequency in the vicinity of 3 to 4KHZ, and the speaker 11B is suitable for sounding alarm sound having a frequency in the vicinity of 2 to 3KHZ. The speaker 11C is suitable for sounding an alarm sound having a frequency in the vicinity of 1 to 2 KHZ. The alarm sound generation controller U has an alarm timing determination means for determining whether or not a plurality of alarm sounds are simultaneously activated by looking at the alarm generation request signals from the plurality of vehicle-mounted devices 10A to 10D. When it is determined by the alarm timing determination means that a plurality of alarm sounds are operated with the same operation timing, only one alarm sound corresponding to the alarm content with the highest alarm level is selected and the selected alarm sound is selected. Alarm sound selection means for performing an alarm by only one alarm sound. As a speaker to be blown, one suitable speaker is selected according to the frequency among the speakers 11A to 11C. Further, the alarm sound generating controller U stores sound patterns corresponding to many alarm sounds according to the alarm contents. With the configuration as shown in FIG. 11, it is only necessary to output a request signal for generating an alarm sound without providing a speaker or the like for each of the in-vehicle devices 10 </ b> A to 10 </ b> D (the alarm sound is concentrated by the controller U). Controlled).

  Although the embodiment has been described above, the present invention is not limited to the embodiment, and can be appropriately changed within the scope described in the scope of claims. For example, the invention includes the following cases. . The number of stages for setting the warning level is merely an example, and can be set to an appropriate stage such as 6 or 12 stages. Moreover, the content of the alarm according to each warning level is also an example, and can be set differently from the above-described setting. The correspondence relationship between the warning level and the target warning level index is an example, and a different target warning level index can be set for each warning level (the higher the warning level, the higher the target warning level). The index is set to be large). For each alarm sound, a target warning degree index can be directly assigned in correspondence with the contents of the warning (omitting the step of assigning the warning degree level). Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
