Washed away.

  The microcomputer 18 of the smartphone 12 appropriately executes the above-described execution necessity determination control program and ANC function control program stored in the memory 26 when the conditions are met.

  When the microcomputer 18 executes the ANC function control program stored in the ANC function control program storage unit 26A of the memory 26, as shown in FIG. 4, an engine rotation frequency detection circuit 72, a reference signal generation circuit 74, and A feedforward type ANC function (also referred to as an ANC main body function) 78 composed of the ANC circuit 76 is realized. In this case, the ANC function further includes the microphone 22 of the smartphone 12, the amplifier 58 of the vehicle 100, the in-vehicle speaker 16, and the like.

The engine pulse Ep is input to the engine rotation frequency detection circuit 72 of the microcomputer 18.

(ANC device)
For the processing as the ANC device in the active acoustic control system 10, for example, the processing described in Patent Document 2 can be basically used.

  That is, the frequency (engine rotation frequency fe) [Hz] of the engine pulse Ep is detected by the engine rotation frequency detection circuit 72 such as a frequency counter. Next, a reference signal generation circuit 74 generates a cosine wave and / or sine wave reference signal Sr based on the engine rotation frequency fe. Further, the adaptive filter 82 of the ANC circuit 76 performs adaptive filter processing on the reference signal Sr. The control signal after the adaptive filter processing is converted into an analog signal by a D / A converter (not shown), and the control signal after the analog processing is supplied to the amplifier 58 through the in-vehicle ECU 50 (see FIG. 4) functioning as the adder 80.

  The in-vehicle ECU 50 and the FI-ECU 54 are in data communication with each other through an in-vehicle communication line such as a CAN (Controller Area Network).

  Whether or not to execute the ANC function control program stored in the execution necessity determination function control program storage unit 26B described above for the active acoustic control system 10 configured and operated basically as described above. The execution necessity determination function control program shown in FIG. 5 (as described above, the ANC function control program and the execution necessity determination function control program) In addition, for the convenience of understanding, it is also referred to as an active acoustic control program.)

  The microcomputer (hereinafter also simply referred to as a computer) 18 of the smartphone 12 detects whether or not the power switch 30 of itself (the smartphone 12) is turned on in step S1.

  When the power switch 30 is turned on, the supply of power is started from the internal battery 32 to the entire internal circuit of the smartphone 12 including the computer 18 through the voltage adjustment circuit 36.

  In step S1, when the power switch 30 is on, in step S2, the computer 18 detects the power state of the port to which the resistor 38 is connected.

  In step S <b> 3, the computer 18 determines whether there is an external power supply connection based on the in-vehicle battery 60 of the vehicle 100. Specifically, it is determined whether or not the power source of the voltage Vc1 is supplied from the in-vehicle battery 60 of the vehicle 100 through the voltage adjustment circuit 56 and the cradle 14, and the voltage is zero (zero volt) and the power source of the voltage Vc1 is determined. Is determined not to be supplied from the in-vehicle battery 60 (vehicle 100), the ANC function control program is stopped in step S4. In this case, the smartphone 12 is not attached to the slot portion 15 of the cradle 14.

  On the other hand, in the determination of step S3, when it is detected that the power source with the voltage Vc1 is supplied to the charging circuit 34 of the smartphone 12, and it is determined that the power source is supplied from the in-vehicle battery 60 (the smartphone 12 has In the case where it is installed in the slot portion 15 of the cradle 14), in step S4, it is detected whether or not the ANC function control program is stopped.

  The process determination of the first step 4 after determining in step S3 that power is being supplied from the in-vehicle battery 60 to the charging circuit 34 of the smartphone 12 becomes affirmative.

  When it is determined in step S3 that an external power source is connected, the charging circuit 34 charges the internal battery 32 with the power source of the voltage Vc1 obtained by adjusting the voltage Vb1 from the in-vehicle battery 60 by the voltage adjusting circuit 56. The power of the voltage Vb2 from the internal battery 32 is supplied to the voltage adjustment circuit 36, and the power of the voltage Vc2 adjusted by the voltage adjustment circuit 36 is supplied to the entire smartphone 12 including the computer 18. In other words, when the smartphone 12 is mounted on the cradle 14 (step S3: YES), and the power switch 30 of the smartphone 12 is turned on (step S1: YES), the voltage adjustment circuit 56 and the charging circuit from the in-vehicle battery 60 are turned on. Since the internal battery 32 is charged through the battery 34 and power is supplied to the entire smartphone 12 from the charged internal battery 32, the smartphone 12 is substantially supplied with power from the in-vehicle battery 60. Note that power is supplied from the in-vehicle battery 60 when an ignition switch (not shown) for the vehicle 100 is turned on.

  In the flowchart of FIG. 5, when the power switch 30 of the smartphone 12 is turned on, execution of the program is started. However, the present invention is not limited to this, and even if the power switch 30 is turned off, When the program is executed from the process of step S2 and the computer 18 in the sleep state when the smartphone 12 is mounted on the cradle 14 detects the voltage Vc1, the power switch 30 is automatically turned on, and the computer 18 The program can be changed to be in a wake-up state.

  In the process of step S3, instead of the computer 18 detecting the voltage Vc1, a photo interrupter is mounted on the cradle 14, and the smartphone 12 as a portable terminal is mounted (inserted) on the cradle 14. When the light path of the photo interrupter is blocked by the casing of the smartphone 12, the in-vehicle ECU 50 that detects the interruption causes the specific port connected to the computer 18 of the smartphone 12 from the low level to the high level through the connectors 44 and 42. By sending a signal that transitions to a level, the computer 18 may determine that there is an external power source connection based on the in-vehicle battery 60 when the signal is received.

  Next, in step S <b> 5, the computer 18 acquires the vehicle name and model of the vehicle 100 from the in-vehicle ECU 50.

  Next, in step S6, the computer 18 refers to the correction filter storage unit 26C and determines whether or not the correction filter 84 corresponding to the vehicle name and model acquired in step S5 is stored.

  If the correction filter 84 corresponding to the vehicle name and model acquired in step S5 is not stored in the correction filter storage unit 26C, the computer 18 accesses the external server device 40 via the communication unit 28 in step S7. Then, the correction filter 84 corresponding to the vehicle name and the model is acquired from the external server device 40 by communication (downloaded) and stored in the correction filter storage unit 26C.

  When the determination in step S6 is affirmative, or when the correction filter 84 is acquired from the external server device 40 (processing in step S7), in step S8, the computer 18 transmits the ANC function from the ANC function control program storage unit 26A. The control program is read and the ANC function control program related to the above-described processing (ANC device) is executed.

  Thereafter, when the power switch 30 is in the on state and the state where the smartphone 12 is attached to the cradle 14 is continued, the determination in step S1 is positive, the processing in step S2, the positive determination in step S3, and the determination in step S4 is negative. Therefore, the execution of the ANC function control program in step S8 is continued.

  On the other hand, when the smartphone 12 is removed from the cradle 14 while the power switch 30 is on and the execution of the ANC function control program is continued, the determination is made based on the voltage across the resistor 38 detected in step S2. In the power supply state, since the voltage is detected as a zero value, the determination in step S3 is negative, and the execution of the ANC function control program is stopped in step S9.

  As described above, the active acoustic control system 10 according to the above-described embodiment includes the microphone 22, the ANC function control program, and the memory 26 (26A, 26B) that stores the program for determining whether or not to execute the ANC function control program. , 26C), and a smartphone 12 that includes a computer 18 that executes an ANC function control program (including an execution necessity determination function control program), a cradle 14 that is provided in the vehicle 100 and to which the smartphone 12 can be attached and detached, The computer 18 includes an in-vehicle speaker 16 connected to the cradle 14, and the computer 18 takes in the error signal e of the microphone 22 and executes the ANC function control program to generate a control signal to be output as a canceling sound through the in-vehicle speaker 16. Compu Motor 18 detects that the smartphone 12 is mounted on the cradle 14, and is configured to execute the ability ANC function control program.

  According to this embodiment, a microphone 22, a memory 26 for storing a program for determining whether the ANC function control program and the ANC function control program need to be executed, and a computer 18 for executing the ANC function control program are provided. When the computer 18 detects that the smartphone 12 is mounted on the cradle 14 provided in the vehicle interior, the computer 18 executes the ANC function control program. Therefore, it is possible to provide the active acoustic control system 10 which is low in cost, small, light and versatile.

  In this case, since the active acoustic control program is executed by the computer 18 only when the smartphone 12 is mounted on the cradle 14 and the microphone 22 is fixed at a specific position (predetermined position), the sound silencing effect is stably obtained. be able to. That is, since the position of the microphone 22 and the position of the in-vehicle speaker 16 are fixed, a silencing effect can be stably obtained.

  Note that the smartphone 12 includes a communication unit 28 that can communicate with the external server device 40, and the correction filter 84 {control characteristics (the microphone 22 and the in-vehicle speaker 16 are compatible with the vehicle name and model of the vehicle 100) from the external server device 40. )} Is downloaded, the smartphone 12 can easily realize ANC function control suitable for the vehicle 100.

  By simply placing the ANC function control program on the smartphone 12, the ANC function control in the passenger compartment can be realized using the microphone 22 and the in-vehicle speaker 16 of the smartphone 12, so that the ANC function can be provided at a low cost. It becomes possible, and it can contribute to the spread of the ANC function which raises the comfort of vehicles.

  The present invention is not limited to the above-described embodiment. For example, instead of the feed-forward type ANC function 78, the phase amount depends on the frequency of the engine noise signal from the engine noise signal received by the microphone 22. A control signal is generated using a variable phase shifter that is variable and a variable amplifier whose gain is variable depending on the frequency of the engine noise signal, and the generated control signal is set as a cancellation signal through the amplifier 58 to cancel the sound from the speaker 16. For example, a feedback-type ANC function to be output as an audio signal (the audio signal may be canceled by a known echo canceller) can be used based on the description in this specification.
