It transmits to the vehicle-mounted control apparatus 11.

  When the contact area detected by the touch sensor 14 is equal to or greater than the threshold value, the input of the touch button 15 corresponding to the contact position or the selection of the icon is confirmed. In addition, scrolling is determined from the change in the contact position. Note that the touch sensor 14 may be a sensor such as a pressure-sensitive sensor or an infrared sensor in addition to the capacitive sensor.

  The speaker 17 (second output means) is an output device that outputs sound and sound.

  The in-vehicle control device 11 is configured as a computer including a CPU, a ROM, a RAM, an I / O, and the like. The CPU executes a program stored in the ROM, thereby executing control linked to the portable terminal 20.

  Specifically, when the connection between the wireless I / F 12 and the wireless I / F 22a of the mobile terminal 20 is established, the in-vehicle control device 11 generates vibration when an input operation on the touch button 15 is detected by the touch sensor 14. Trigger (detection signal) is transmitted from the wireless I / F 12 to the wireless I / F 22a.

  In addition, when the in-vehicle control device 11 is set to output an operation sound in response to detection of an input operation on the touch button 15, the in-vehicle control device 11 starts from the speaker 17 in response to detection of the input operation by the touch sensor 14. The operation sound is output.

  The mobile terminal 20 includes a mobile control device 21, a communication unit 22, an HMI 23 (Human Machine Interface), and a vibration motor 24.

The wireless I / F 22a is connected to a wireless access point via Wi-Fi, and performs wireless communication with a communication device different from the in-vehicle device 10 via the wireless access point. Further, the communication I / F 22b performs wireless communication with a communication device different from the in-vehicle device 10 via the base station 30.

  The HMI 23 is an input / output device including a display screen composed of a liquid crystal panel, various operation switches, a speaker (first output means) for outputting sound, and the like.

  The vibration motor 24 (vibration means) is an actuator that is driven in accordance with a drive signal from the portable control device 21 to generate vibration. Instead of the vibration motor 24, an actuator such as a piezoelectric element or a voice coil may be used.

  The vibration pattern generated by the vibration motor 24 is set by the user from the HMI 23. When the connection between the wireless I / F 12 and the wireless I / F 22a of the in-vehicle device 10 is established, the portable control device 21 displays a vibration pattern setting screen on the HMI 23, so that the user sets the vibration pattern for receiving the trigger from the HMI 23. it can. In addition, if the wireless I / F 12 of the in-vehicle device 10 and the wireless I / F 22a of the mobile terminal 20 are connected, the user can set a vibration pattern for trigger reception from the in-vehicle device 10 side.

  Here, different vibration patterns are set for each user depending on whether the communication unit 22 receives a trigger from the vehicle-mounted device 10 and the communication unit 22 receives a mail or a telephone call from a communication device other than the vehicle-mounted device 10. Accordingly, the vibration motor 24 generates different patterns of vibration when the communication unit 22 receives a trigger from the in-vehicle device 10 and when the communication unit 22 receives from another communication device. Generally, a pattern in which a vibration with a short vibration period is generated once for reception from the vehicle-mounted device 10 and a pattern with a long vibration period is repeatedly generated for reception from other communication devices. Set to

Is set.

  The portable control device 21 is configured as a computer including a CPU, ROM, RAM, I / O, and the like. The CPU executes various controls by executing applications stored in the ROM.

  Specifically, when the trigger transmitted from the wireless I / F 12 is received by the wireless I / F 22a, the portable control device 21 outputs a drive signal to the vibration motor 24 and causes the vibration motor 24 to generate vibration. At this time, the portable control device 21 outputs a drive signal corresponding to the vibration pattern set for the reception of the trigger from the in-vehicle device 10, and the vibration is set with the vibration pattern set for the reception of the trigger. Vibration is generated by the motor 24.

  In addition, when the mobile control device 21 is set in the vibration mode and the reception from the in-vehicle device 10 by the communication unit 22 and the reception from another communication device by the communication unit 22 overlap, The process at the time of competition is performed so that reception from the in-vehicle device 10 and reception from other communication devices can be discriminated. Details of the contention process will be described later.

  Furthermore, when the portable control device 21 is set to output an operation sound in response to reception of a trigger by the wireless I / F 22a, the portable control device 21 outputs an operation sound from the speaker of the HMI 23 in response to reception of the trigger. .

  In the case where the in-vehicle control device 11 or the portable control device 21 is set to output the operation sound of the touch button 15 in both the in-vehicle device 10 and the portable terminal 20, the touch is performed from the priority side. An operation sound is output in response to detection of an input operation on the button 15. That is, the in-vehicle control device 11 or the portable control device 21 outputs the operation sound of the touch button 15 from either the speaker 17 or the speaker of the HMI 23. Thereby, the operation sound is output from both the in-vehicle device 10 and the portable terminal 20, and there is no possibility that the user feels noisy.

  Next, a processing procedure in which the mobile terminal 20 generates vibration according to an input operation to the in-vehicle device 10 by the user will be described with reference to the flowcharts of FIGS. 3 and 4. First, with reference to the flowchart of FIG. 3, the process which the vehicle-mounted control apparatus 11 of the vehicle equipment 10 repeatedly performs is demonstrated.

  First, it is determined whether or not the user has performed an input operation on the touch button 15, that is, whether or not the input operation on the touch button 15 has been detected by the touch sensor 14 (S10). Specifically, based on the signal transmitted from the touch sensor 14, when the user's finger is in contact with the touch button 15 and the contact area of the user's finger is equal to or larger than the threshold, the touch sensor 15 It is determined that an input operation for is detected.

  When an input operation to the touch button 15 is detected (S10: YES), a trigger for generating vibration is transmitted from the wireless I / F 12 to the wireless I / F 22a of the mobile terminal 20 (S11), and this processing is performed. Exit. If an input operation on the touch button 15 is not detected (S10: NO), the process of S10 is repeated.

  Next, with reference to the flowchart of FIG. 4, the process which the portable control apparatus 21 of the portable terminal 20 repeatedly performs is demonstrated. In this process, it is assumed that the vibration mode is set by the user.

  First, it is determined whether there is an incoming mail or telephone (S20). That is, it is determined whether the communication unit 22 is receiving from a communication device other than the in-vehicle device 10.

  If there is an incoming mail or telephone call (S20: YES), the vibration motor 24 generates vibrations with the vibration pattern set for reception from other communication devices, and notifies the user of the incoming call ( S21). On the other hand, when there is no incoming mail or telephone (S20: NO), the process proceeds to the next process.

  Subsequently, it is determined whether or not the trigger transmitted from the wireless I / F 12 of the in-vehicle device 10 is received by the wireless I / F 22a (S22). If a trigger has not been received (S22: NO), the process returns to S20.

  On the other hand, if a trigger is received (S22: YES), it is subsequently determined whether there is an incoming mail or telephone (S23). That is, it is determined whether or not the reception of the trigger from the in-vehicle device 10 by the communication unit 22 and the reception of a mail or a telephone from another communication device by the communication unit 22 are overlapped. If there is an incoming call (S23: YES), the reception of the trigger and the incoming mail or telephone are overlapped, so the process at the time of competition is performed (S24).

  Specifically, the vibration motor 24 generates a vibration with a vibration pattern corresponding to the reception of the trigger while generating a vibration with a vibration pattern corresponding to the reception from another communication device. Thereby, the vibration which alert | reports the confirmation of the input of the touch button 15 generate | occur | produces between the vibrations which alert | report the reception from another communication apparatus repeatedly.

  Alternatively, the vibration mode is canceled and the vibration is generated by the vibration motor 24 using only the vibration pattern corresponding to the reception of the trigger. And the ringtone corresponding to reception from another communication apparatus is output with the speaker of HMI23. In this case, when this processing procedure is repeatedly executed, the vibration mode is canceled until it is determined in step S22 that the trigger is not received, and the vibration mode is set when it is determined that the trigger is not received. return. In this way, even when the user continuously performs an input operation on the touch button 15, an incoming mail or phone call is notified by a ring tone while the user continuously performs the input operation. The Therefore, the user can discriminate between confirmation of continuous input operations and incoming mail and telephone calls.

  On the other hand, when there is no incoming call (S23: NO), vibration is generated by the vibration motor 24 with the vibration pattern set for the reception of the trigger to notify the user that the input of the touch button 15 is confirmed ( S25). This process is complete | finished above.

  According to this embodiment described above, the following effects are obtained.

  -Even if it does not mount a vibration motor in the vehicle equipment 10, the vibration according to input operation with respect to the touch button 15 can be generated by using the vibration motor 24 of the portable terminal 20. FIG. Therefore, by linking the in-vehicle device 10 having a simple configuration not including the vibration motor and the portable terminal 20 generally including the vibration motor, the user is given a feeling corresponding to the input operation on the touch button 15. Can do.

  Since the vibration motor 24 generates different patterns of vibration for receiving a trigger and receiving an e-mail or a phone call, the user confuses the vibration for notifying the input operation to the touch button 15 with the vibration for notifying the incoming call. There is no fear.

  -When reception of the trigger by the communication part 22 of the portable terminal 20 and incoming calls such as e-mails and telephones overlap, vibrations notifying the input operation to the touch button 15 occur between the occurrences of vibrations notifying incoming calls. Occur. Therefore, even when the input operation on the touch button 15 and the incoming call overlap, the user can obtain a touch according to the input operation and can recognize the incoming call.

  ・ Alternatively, when a trigger received by the communication unit 22 of the mobile terminal 20 and an incoming mail or phone call overlap, vibration to notify the input operation of the touch button 15 is generated, but vibration to notify the incoming call is generated. do not do. Instead, a ring tone for notifying an incoming call is output. Therefore, when the input operation on the touch button 15 and the incoming call overlap, the user can recognize the input operation and the incoming call without confusion.

  -By connecting the vehicle-mounted device 10 and the mobile terminal 20 by wireless communication, the user can wear the mobile terminal 20 and get a feel for an input operation on the touch button 15 without being troubled by wiring. .

  In response to detection of an input operation on the touch button 15, an operation sound is output from either the in-vehicle device 10 or the mobile terminal 20. Therefore, the user can get a feel corresponding to the input operation, and can also recognize the input operation with an operation sound.
