Description

  The present invention relates to an on-vehicle device operation device and a stimulation output method for modulating waveform data according to a hierarchy and outputting it as a stimulus when operating an on-vehicle device that provides information having a plurality of layers.

  In recent years, many in-vehicle devices such as audio devices and navigation devices are mounted on vehicles. However, in order to operate these in-vehicle devices while driving, it is necessary to be able to operate them without looking at the display screen or switches. Therefore, there has been an attempt to improve the operability during driving by increasing the efficiency of blind touch by transmitting the currently selected operation item to the driver using an information transmission path other than vision. Has been done.

  In view of such circumstances, the operation device of the automotive control device disclosed in Patent Document 1 discloses a method of transmitting the content of the selected operation item with a language and transmitting it by voice. In addition, in the on-vehicle device operation device disclosed in Patent Document 2, a method of transmitting a selected operation item using tactile transmission information such as a change in operation drag or vibration is disclosed.

Japanese Patent Laid-Open No. 10-274541 JP 2000-149721 A

 However, in the conventional technology described above, since only the same voice information, acoustic stimulation, and vibration stimulation are always given for the operation by the operator, when operating an in-vehicle device that provides information having a plurality of layers, There is a problem in that it is impossible to transmit the position of the currently operated hierarchy (hierarchy depth) or to efficiently convey that the hierarchy operation is approaching the final stage.

 For example, when performing a hard disk audio song selection operation, the operator views the display screen assuming that the target song should be displayed second from the top of the list presented on the “song selection screen”. Suppose that the list feed operation is performed. At this time, if the operator is still in the “album selection screen” one level before the “song selection screen” due to the misunderstanding of the operator, the operator can select the target song even if he / she makes a selection decision without noticing his / her wrong operation. Will be confused without being played. In addition, since the operator has to visually confirm the display screen, the operability cannot be improved.

 Therefore, the present invention has been proposed in view of the above-described situation, and when operating an in-vehicle device that provides information having a plurality of levels, the level currently being operated can be easily recognized. An object of the present invention is to provide an on-vehicle device operating device and a stimulus output method.

The in-vehicle device operating device according to the present invention stores an input unit for inputting an operation to the in-vehicle device and reference waveform data set for each in-vehicle device, and when the in-vehicle device to be operated is selected by the input unit. A waveform data selection unit that selects reference waveform data corresponding to the in-vehicle device to be operated, and waveform data that generates modulated waveform data by modulating the reference waveform data in accordance with the hierarchy of information provided by the in-vehicle device to be operated a modulation unit, a modulation data adding unit that generates a modulated additional data by adding the modulated data to the modulation waveform data in accordance with the vehicle data regarding the traveling state of the vehicle, the modulation additional data corresponding to a hierarchy is operated by the input unit and an output unit for outputting the stimulation by the modulation data adding unit, sequentially increasing the pitch of the tail portion of the modulated additional data when the speed of the vehicle is a predetermined value or more, By sequentially lower the pitch of the tail portion of the modulated additional data when the speed of the vehicle is less than a predetermined value, to solve the problems described above.

  According to the operation device for in-vehicle devices according to the present invention, the reference waveform data set for each in-vehicle device is modulated according to the hierarchy of information provided from the in-vehicle device. When operating a device, it is possible to easily recognize the hierarchy currently being operated. This eliminates the need for the driver to look at the display screen and does not shift his line of sight from the front, thus improving safety.

[First Embodiment]
[Configuration of control device for in-vehicle equipment]
FIG. 1 is a block diagram showing the configuration of the on-vehicle device operating device according to this embodiment.

  As shown in FIG. 1, the on-vehicle device operating device 1 according to the present embodiment provides an input unit 2 that is a switch unit including various switches, and provides acoustic stimulation and vibration stimulation based on an operator's input. Control unit 3 that performs the processing to be performed, waveform data selection unit 4 that stores reference waveform data set for each in-vehicle device and selects reference waveform data corresponding to the in-vehicle device to be operated, and in-vehicle device to be operated The waveform data modulation unit 5 that modulates the reference waveform data according to the information hierarchy provided to generate modulation waveform data, and the waveform data storage unit that stores the modulation waveform data generated by the waveform data modulation unit 5 6, a delay mechanism 7 that outputs a trigger signal when the input unit 2 is operated, and modulation waveform data corresponding to the hierarchy operated by the input unit 2 is output as an acoustic stimulus or a vibration stimulus An output unit 8, a GUI data selection unit 9 that selects screen data necessary for screen display, a display controller 10 that controls screen display, and a display 11 that provides an operator with a display of operation screens and operation results. I have.

  Here, when operating each in-vehicle device such as an audio device, a telephone, and a navigation device, the in-vehicle device operation device 1 according to the present embodiment performs, for example, an audio operation to select “artist name selection” from “artist selection”. ”And“ song selection ”as the hierarchy changes, stimuli such as acoustic stimuli are changed and provided to the operator.

  The input unit 2 is a switch unit in which an input for operating an in-vehicle device is performed by an operator, a seesaw switch device 21 for operating a list up and down, and a determination for determining a list selected by a feed operation An operation button 22 is provided.

  The control unit 3 executes an operation to the in-vehicle device requested by the operator in response to an operation input from the input unit 2, and executes a stimulus output process for outputting a stimulus according to a change in the hierarchy to the operator doing.

  The waveform data selection unit 4 stores reference waveform data set for each in-vehicle device such as audio, telephone, and navigation device, and corresponds to the in-vehicle device to be operated when the in-vehicle device to be operated is selected. The selected reference waveform data is selected and read. For example, when the operator selects audio as the in-vehicle device to be operated, reference waveform data corresponding to audio is selected and read.

  The waveform data modulation unit 5 modulates the reference waveform data according to the hierarchy. For example, when the hierarchy changes from “artist selection” to “album name selection” or “song selection”. First, modulation is performed so that the degree of modulation increases as the hierarchy changes. The reference waveform data thus modulated is output as modulated waveform data.

  The waveform data storage unit 6 stores the modulated waveform data modulated by the waveform data modulation unit 5, and when there is an input from the operator in the input unit 2, the stored modulation waveform data is hierarchically stored. Outputs the corresponding modulation waveform data. For example, when the level changes from “album name selection” to “song selection” and the determination operation button 22 is pressed, the modulated waveform data corresponding to the “song selection” level in response to the input of the trigger signal Is output.

  The output unit 8 outputs a stimulus corresponding to the modulated waveform data to the operator, and includes an amplifier 81 and a speaker 82 for outputting an acoustic stimulus, and an actuator 83 for outputting a vibration stimulus. ing. Although FIG. 1 shows a case where both an acoustic stimulus and a vibration stimulus can be output, only one of the stimuli may be output.

[Procedure output procedure]
Next, the procedure of the stimulus output process by the in-vehicle device operation device 1 according to the present embodiment will be described with reference to the flowchart of FIG. In the stimulus output process performed here, for example, the input unit 2 is operated by the operator, the hard disk audio is selected from the in-vehicle device, and “artist selection”, “ This process is performed when the target music is listened to in a hierarchical operation and selection in the order of “album name selection” and “music selection”.

  As shown in FIG. 2, in step S <b> 101, the operator operates the input unit 2 to select an in-vehicle device to be operated. For example, when hard disk audio is selected from in-vehicle devices such as audio, telephone, and navigation device, the controller mounted in the control unit 3 performs the operation requested by the operator on the in-vehicle devices. Start hard disk audio. Further, the GUI data selection unit 9 selects necessary screen data in accordance with the operation logic based on an instruction from the control unit 3, and an initial hard disk audio is displayed on the display 11 constituted by a liquid crystal or the like via the display controller 10. Display the screen.

  Next, in step S102, the control unit 3 displays in-vehicle device information including information indicating which in-vehicle device is being operated among the in-vehicle devices such as audio, telephone, and navigation device at each operation time point. 4 to send.

  Here, the waveform data selection unit 4 is a storage device, and stores reference waveform data set in advance for each in-vehicle device such as an audio, a telephone, and a navigation device. In step S103, the waveform data selection unit 4 selects the reference waveform data of the in-vehicle device that is the operation target from the preset reference waveform data based on the in-vehicle device information, and the waveform data modulation unit Send to 5. For example, here, the reference waveform data of the hard disk audio is selected and transmitted to the waveform data modulator 5.

  Next, in step S104, the control unit 3 transmits hierarchy information including information on what hierarchy the in-vehicle device to be operated has to the waveform data modulation unit 5 and proceeds to step S105.

  In step S105, the waveform data modulator 5 modulates the reference waveform data based on the hierarchy information to generate modulated waveform data. Here, the waveform data modulation unit 5 is composed of a data storage device and a device for controlling the reading interval of the stored data, and the modulated waveform data modulated at a high pitch by setting the reading time short. Generated and modulated waveform data modulated at a low pitch by setting a long readout time. Further, when the reference waveform data is modulated, it may be modulated in proportion to the number of layers. For example, one octave may be modulated for each layer. As a result, the operator can easily recognize the depth of the hierarchy.

  When modulated waveform data is generated by being modulated to a predetermined pitch in this way, the modulated waveform data is stored in the waveform data storage unit 6 in step S106.

  When the hierarchy is changed from “artist selection” to “album name selection” or “song selection” in the input unit 2 and the determination operation button 22 is operated, the operation result is displayed in the delay mechanism 7. The waveform data storage unit 6 transmits the modulated waveform data to the output unit 8 in step S107 in response to the trigger signal.

  When outputting an acoustic stimulus in step S108, the output unit 8 transmits the modulated waveform data to the amplifier 81 and amplifies it, and then outputs it as an acoustic stimulus to the operator via the speaker 82. On the other hand, in the case of outputting a vibration stimulus, the modulation waveform data is transmitted to the actuator 83 to convert the electric signal into a vibration stimulus and output it to the operator.

  Thus, when an acoustic stimulus or a vibration stimulus is provided to the operator, the stimulus output process by the in-vehicle device operation device 1 according to the present embodiment ends.

  The determination unit 33 determines whether or not the vehicle data acquired by the vehicle data acquisition unit 32 exceeds a predetermined value, and outputs the determination result to the modulation data addition unit 34.

  The modulation data adding unit 34 adds modulation data whose pitch height temporarily changes to the latter half of the modulation waveform data processed by the waveform data modulation unit 5 to a predetermined height pitch, thereby adding the modulation additional data. It has a function to generate. Thereby, for example, when it is assumed that the cruising speed of the vehicle is high and the driving load is high, when the determination operation button 22 of the input unit 3 is operated, the pitch is increased toward the second half as an operation confirmation sound. An acoustic stimulus modulated to be higher is output to the operator. By outputting such an acoustic stimulus that increases the pitch in the latter half, the operator can easily understand that the situation is different from that during normal operation.

[Procedure output procedure]
Next, a procedure of stimulus output processing by the in-vehicle device operation device 31 according to the present embodiment will be described with reference to the flowchart of FIG. However, the processing from step S201 to S205 shown in FIG. 4 is the same as the processing from step S101 to S105 shown in FIG.

  As shown in FIG. 4, when the modulated waveform data is generated by modulating the reference waveform data to a predetermined pitch in step S205, the determination unit 33 determines in step S206 whether the vehicle data exceeds a predetermined value. Determine. For example, it is determined whether the vehicle speed is higher than a predetermined value or the inter-vehicle distance is closer than a predetermined value, and the determination result is transmitted to the modulation data adding unit 34.

  Next, in step S207, the modulation data adding unit 34 adds modulation data to the modulation waveform data and sequentially increases the pitch of the end portion when the vehicle data is equal to or greater than a predetermined value based on the determination result of the determination unit 33. When the vehicle data is less than the predetermined value, the modulation additional data is generated by adding the modulation data to the modulation waveform data and sequentially lowering the pitch of the end portion. For example, when the speed of the host vehicle is equal to or higher than a predetermined value, the pitch of the tail portion of the modulation additional data is sequentially increased, and when the speed of the host vehicle is less than the predetermined value, the pitch of the tail portion of the modulation additional data is sequentially decreased. When the modulation addition data is generated in this way, the modulation addition data is stored in the waveform data storage unit 6 in step S208.

  When the hierarchy is changed from “artist selection” to “album name selection” or “song selection” in the input unit 2 and the determination operation button 22 is operated, the operation result is displayed in the delay mechanism 7. As a trigger signal, it is input to the waveform data storage unit 6, and in response to this trigger signal, the waveform data storage unit 6 transmits the modulation additional data to the output unit 8 in step S 209.

  Next, in step S210, when outputting the acoustic stimulus, the output unit 8 transmits the modulated additional data to the amplifier 81 and amplifies it, and then outputs it as an acoustic stimulus to the operator via the speaker 82. On the other hand, in the case of outputting a vibration stimulus, the modulation additional data is transmitted to the actuator 83 to convert the electric signal into a vibration stimulus and output it to the operator.

  Thus, when an acoustic stimulus or a vibration stimulus is output to the operator, the stimulus output process by the in-vehicle device operation device 31 according to the present embodiment is completed.

[Effects of Second Embodiment]

The operator can know the operation tempo according to the vehicle situation, and the safety of the display can be improved because the operator does not carelessly view the display or the operation switch.

  Further, according to the on-vehicle device operating device, when the speed of the host vehicle is equal to or higher than a predetermined value, the pitch of the tail portion of the modulation additional data is sequentially increased, and when the speed of the host vehicle is lower than the predetermined value, the modulation additional data Since the pitch of the tail part of the head is sequentially lowered, the operator can easily understand that the situation is different from that during normal operation.
