Description

  The present invention relates to an on-vehicle device that generates an operation sound based on an input operation to an operation unit.

In the case of a device such as a smartphone or a television receiver that operates by focusing on the screen, input confirmation such as button operation and key operation can be performed by visual feedback by screen animation, so based on the input operation Since the operation sound is bothersome, it hardly generates any key operation.
On the other hand, in-vehicle devices such as navigation devices generate operation sounds for various button and key operations so that they can be operated safely and reliably even while driving. Thereby, while driving the vehicle, it is possible to confirm the operation input without paying attention to the operation screen.

  In order to secure the input of the button and the key operation accompanied with the generation of such an operation sound, there has been proposed an electronic device which generates an operation sound appropriate for the key operation of the user (see Patent Document 1). In this electronic device, in addition to the case where the key operation is valid or invalid, the operation sound to notify acceptance is generated even if the judgment of valid or invalid can not be made, so the key operation is surely performed without looking at the operation screen. Can recognize what

  According to the electronic device described in Patent Document 1, since the operation sound corresponding to any key operation is immediately generated, the input of the key operation can be confirmed even while traveling. However, when the vehicle is in automatic operation, it is possible to perform an operation focusing on the operation screen, and it is possible that the number of operations also increases. However, when an operation sound is generated for each key operation as described above, feedback becomes excessive. This may disturb the operator's relaxation and cause discomfort. Furthermore, a warning sound or the like for notifying an important matter may be buried in various operation sounds and may not be notified.

  An object of the present invention is to provide an in-vehicle device that changes an operation sound based on an input operation to an operation unit to an operation sound in a normal mode and an operation sound in a quiet mode in a predetermined traveling state or the like.

In order to solve the above problems, an on-vehicle apparatus according to the present invention is an on-vehicle apparatus that displays an image based on an input operation to an operation unit by an operator on a display unit and generates an operation sound. Running state detection means for detecting whether or not the vehicle to be driven is in a predetermined running state, and the operation sound when the running state detection means detects that the vehicle is in a predetermined running state Operation sound control means for changing the operation sound of the normal mode into the operation sound of the quiet mode, and the predetermined traveling state is a state in which the vehicle is in an automatic driving state .

According to such a configuration, when it is detected that the vehicle is in a predetermined traveling state, the operation sound based on the input operation is changed from the operation sound in the normal mode to the operation sound in the quiet mode. Discomfort caused by the occurrence can be suppressed. With regard to a predetermined traveling state, for example, in the case of automatic driving, the case where the input operation can be confirmed even if the operation sound is not generated is applicable. Since the vehicle is in the state of automatic driving, the user can visually recognize the image based on the input operation even when the operator is the driver. Therefore, the operation sound can be silent regardless of the operator. It can be done. As a result, it is possible to suppress the occurrence of annoyance and annoyance due to the operation sound in the normal mode.

Vehicle device according to the present invention, displays an image based on the input operation to the operation portion by the operator on the display unit, a vehicle device that generates an operation sound, the operator is a driver of vehicles The operation sound from the operation sound of the normal mode to the operation of the quiet mode when the operator detection means for detecting whether or not the operator detection means detects a person other than the driver of the vehicle by the operator detection means And an operation sound control unit configured to change to a sound.

  According to such a configuration, when it is detected that the person performing the input operation is a person other than the driver, the image based on the input operation can be visually recognized, and thus it is necessary to perform the input confirmation by the operation sound. Since there is not, it is possible to change the operation sound from the normal mode to the quiet mode, and to suppress the generation of the annoyance and annoyance due to the operation sound.

In the on-vehicle apparatus according to the present invention, the operation sound in the silent mode may be an operation sound obtained by reducing the volume of the operation sound in the normal mode to zero or reduced. In addition, as the operation sound in the silent mode, the operation sound in the normal mode and the predetermined operation sound having different timbre or sound quality can be used.

  According to such a configuration, by setting the operation sound in the silent mode to zero volume or decrease in volume, it is possible to suppress the generation of annoyance and discomfort due to the operation sound. Furthermore, by changing the timbre and sound quality to a predetermined operation sound accompanied by quietness, it is possible to suppress the generation of annoyance and annoyance due to the operation sound.

  In the on-vehicle apparatus according to the present invention, the operator detection unit may be a proximity sensor that detects a proximity direction of an operator approaching the operation unit.

  According to such a configuration, it is possible to detect whether the operator who performs the input operation using the proximity sensor is a driver or someone other than a transferee. Since the direction in which the user approaches the input unit during the input operation is different, this can be detected by the proximity sensor.

  In the on-vehicle apparatus according to the present invention, the proximity sensor can be configured as any one of an optical sensor, an ultrasonic sensor, a magnetic sensor, an electromagnetic wave sensor, and a capacitance sensor.

  According to such a configuration, the proximity of the operator and the proximity of the operator can be obtained by using an optical sensor such as infrared light, an ultrasonic sensor, a magnetic sensor, an electromagnetic wave sensor, and a capacitance sensor as the proximity sensor. The direction of movement can be accurately detected.

  In the on-vehicle apparatus according to the present invention, the input operation to the operation unit may be a touch operation on a touch panel provided in the display unit.

  According to such a configuration, since the input operation is a touch operation on the touch panel provided on the screen, the confirmation of the input operation can be easily confirmed by the image on the display unit.

  According to the on-vehicle apparatus of the present invention, when the vehicle is in a predetermined traveling state or the like, the operation sound based on the input operation is changed from the operation sound in the normal mode to the operation sound in the quiet mode. The occurrence of discomfort can be suppressed.

  Embodiments of the present invention will be described using the drawings.

  A block diagram of an on-vehicle apparatus according to an embodiment of the present invention is shown in FIG.

  In FIG. 1, an on-vehicle device 11 has a processing unit 12 configured by a computer unit (for example, including a CPU, a ROM, a RAM, an I / O interface, a bus, and the like). Connected to the processing unit 12 are an AV unit 15 capable of reproducing various sound sources and video sources (for example, CD and DVD) and a navigation unit 17 capable of performing navigation of the vehicle. Further, a speaker 18 is connected to the processing unit 12 via an output circuit 19. Accordingly, it is possible to output an audio signal related to the processing of the AV unit 15 and the navigation unit 17 from the speaker 18, and generate an operation sound based on an input (touch) operation to the operation unit (touch panel) 23 described later. It can be done. In addition, the processing unit 12 includes a storage unit 20 (for example, a hard disk, etc.) capable of storing various information such as music information and map information used in the AV unit 15 and the navigation unit 17 and various programs executed in the processing unit 12. A display unit (display) 21 for displaying an image or the like accompanying various processes configured by a flash memory etc. and an LCD etc., and an instruction necessary for various processes formed in a touch panel format on the display unit 21 can be input An operation unit 23 is connected.

  Further, to the processing unit 12, a proximity sensor unit 25 having proximity sensors 25a and 25b is connected. The proximity sensor unit 25 detects the approach of the operator's finger or the like approaching the operation unit 23 for the input operation, and detects the approaching direction and the approaching operator is a driver or a person other than the driver. It has a function to detect whether it is. In order to effectively perform the above detection, as shown in FIGS. 3 and 4, the proximity sensor unit 25 is provided in the lower frame 21 a of the operation unit 23 and the display unit 21. The proximity sensors 25a and 25b constituting the proximity sensor unit 25 are respectively provided at the positions on the left and right of the lower frame 21a.

  Each of the proximity sensors 25a and 25b includes a light emitting unit (not shown) formed of a light emitting element such as infrared light and a light receiving unit (not shown) formed of a light receiving element. The light is reflected by the operator's finger or the like, and the light receiving unit detects the amount of light reflected by the reflection to detect the proximity, and the two proximity sensors 25a and 25b detect the lower frame 21a of the surrounding frame. The proximity sensor unit 25 can detect the proximity of the operator and the proximity direction thereof, and the proximity sensor unit 25 has two proximity sensors instead of the above two in order to improve the function. In addition to the above, as a proximity sensor, a high frequency oscillation type using electromagnetic induction, a magnetic type using a magnet, a capacitance type using a change in capacitance, an ultrasonic wave Ultrasonic type using It is also possible to use one. Moreover, by analyzing the image captured by the vehicle-mounted camera in place of the proximity sensor unit 25 can detect the operator (a person other than the driver, or the driver).

  In the on-vehicle device 11 configured as described above, the process is performed according to the procedure as shown in FIG.

  In FIG. 2, the processing unit 12 starts the process by the operation (switch ON) of the in-vehicle device 11 (S11). The processing unit 12 detects whether the vehicle is traveling (S12: traveling state detection means). Whether or not the vehicle is traveling can be detected by a rotation detection sensor or the like that detects the presence or absence of the rotation of the wheel. When detecting that the vehicle is traveling (YES in S12), the processing unit 12 next detects whether or not the vehicle is in the state of automatic driving (S13: traveling state detection means). When the vehicle is in the state of automatic driving, the display image based on the input operation to the operation unit 23 can be sufficiently viewed regardless of whether the operator is a driver or anyone other than the driver. Therefore, since feedback to the image by the input operation can be confirmed, it is considered that the occurrence of the operation sound for each operation is likely to be bothersome and unpleasant.

  The processing unit 12 that has detected that the vehicle is in automatic driving detects whether or not an input operation (screen touch) on the operation unit (touch panel) 23 has been performed (S14). When the processing unit 12 detects that the operator has performed an input operation to the operation unit 23 (YES in S14), the processing unit 12 performs processing (including image processing and the like) based on the touch position on the screen on which the input operation has been performed. However, since the operation sound is in the quiet mode, the operation sound (normal mode) is not generated based on the input operation (S15: operation sound control means). As described above, when the vehicle is in automatic driving, the operator (driver and persons other than the driver) can visually recognize the display image on the display unit 21 based on the input operation and the input operation, Since the operation sound (normal mode) generated for each input operation is bothersome and uncomfortable, the generation of the operation sound is made unnecessary (volume zero) (silence mode). As a result, the quietness of the room is maintained, and the occurrence of an alarm or the like in an emergency is not missed. In addition, although the volume of the operation sound was made zero in order to set it as a quiet mode, the volume of the operation sound is made lower than the setting volume of the normal mode as a quiet mode, or the timbre of the operation sound and the tone quality are unpleasant for the operator. You may change it to the thing which does not give. Both can be set in advance by the operator.

  In addition, when the processing unit 12 detects that the vehicle is not traveling (stopping) (NO in S12), the operator (driver) is the same as when the above-described vehicle is in the state of automatic driving. And since persons other than the driver can visually recognize the feedback by the display image on the display unit 21 based on the input operation and the input operation, when there is an input operation on the operation unit (YES in S14), The mode is switched to the silent mode in which the volume of the operation sound is zero, and the operation sound is not generated (S15: operation sound control means).

  The processing unit 12 detects whether or not the input operation to the operation unit (touch panel) 23 is a driver when detecting that the driving of the traveling vehicle is not automatic driving (manual driving) (NO in S13) (S16: operator detection means). When the running vehicle is in manual operation, the driver must watch the traveling direction for safety confirmation. Therefore, even when the input operation to the operation unit 23 is performed, the input result is displayed on the screen of the display unit 21. In many cases, it is difficult to confirm the above, and it is necessary to generate an operation sound in order to confirm the input operation. On the other hand, when the operator is a person other than the driver, since the input operation can be confirmed on the screen, by setting the operation sound to the silent mode with zero volume, the user is freed from the bother of having the operation sound Be done.

  As shown in FIGS. 3 and 4, when the operator is a driver (not shown) in order to perform input operation to the operation unit 23 (touch panel) provided on the screen of the display unit 21, driving is performed. The person's finger 31 approaches from the driver's seat 35 toward the operation unit 23 (in the direction indicated by the arrow 37), and the operator sits on the passenger seat 36 (not shown: hereinafter referred to as "passenger seat person" as appropriate) At this time, the finger 32 (indicated by a chain line) of the passenger in the passenger seat 36 approaches from the passenger seat 36 toward the operation unit 23 (in the direction indicated by the arrow 38). It is possible to detect whether the operator is a driver or a passenger by detecting the difference in the direction in which the user approaches the operation unit 23 using the proximity sensors 25a and 25b.

  The processing unit 12 detects the presence or absence of a touch operation on the operation unit 23 (S17) when detecting that the operator in the vehicle during manual driving is a driver (YES in S16). When the processing unit 12 detects that the operator has performed an input operation to the operation unit 23 (YES in S17), the processing unit 12 performs processing (including image processing and the like) based on the touch position on the screen on which the input operation has been performed. At the same time, an operation sound (normal mode) based on the input operation is generated (S18: operation sound control means). Since the driver driving the vehicle manually is the operator, the input operation is confirmed by the operation sound in the normal mode as in the conventional case. When the same input operation as described above is repeated, the operation sound is generated in the normal mode, and when the operation of the in-vehicle device is stopped, the operation ends (S20).

  On the other hand, when the processing unit 12 detects that the operator is not the driver but the passenger, it detects that there is an input operation to the operation unit 23 by the operator (passenger) ( While processing (including image processing etc.) based on the touch position on the screen where the input operation has been performed is performed (YES in S14), the operation mode (normal mode) based on the input operation is not generated since the silent mode is set. (S15: operation sound control means). This is because the passenger who does not perform the driving operation can confirm the input operation by feedback on the screen. When the same input operation as described above is repeated, the volume of the operation sound is zero, the operation sound is not generated, and the operation is ended when the operation of the in-vehicle device is stopped (S19).

  As described above, in the present embodiment, when the vehicle is stopped or traveling automatically, the input operation is displayed on the screen regardless of whether the operator who performs the input operation of the in-vehicle device is a driver or a passenger. Since it can confirm, the volume of the operation sound by input operation is made into zero, and it is set as quiet mode. Thereby, the troublesomeness by the operation sound which generate | occur | produced each time of operation can be eliminated. In addition, when the operator is a person other than the driver (passenger seat etc.), the screen can be viewed regardless of the traveling state of the vehicle, so the silent mode in which the volume of the operation sound is zero is selected. Thus, it is possible to eliminate the inconvenience caused by the operation sound generated each time the operation is performed. As described above, as the quiet mode of the operation sound, the volume of the operation sound may be lower than the set volume in the normal mode, and even if the operator does not feel uncomfortable, even if it is changed to timbre and sound quality Good.

  As described above, according to the present invention, when the vehicle is in a predetermined traveling state or when the operator is a person other than the driver, the operation sound based on the input operation is generated from the operation sound in the normal mode Since the effect of changing to the operation sound in the quiet mode is exhibited, it is possible to provide the on-vehicle device capable of suppressing the occurrence of the complication and the discomfort due to the operation sound.
