That is, each of the passenger seat side seat belt ECU 102 and the driver seat side seat belt ECU 103 detects the amount of rotation of the belt reel 14 (that is, the amount by which the webbing 5 is pulled out) by counting the pulse signal, and the change rate of the pulse signal ( Frequency) is calculated to calculate the rotation speed of the belt reel 14 (that is, the webbing 5 winding speed or drawing speed), and the rotation direction of the belt reel 14 is detected by comparing the rising edges of the waveforms of both pulse signals. To do.

Each of the passenger seat side seat belt ECU 102 and the driver seat side seat belt ECU 103 receives the setting information and the first identification information (for example, the identifier of DAT01) transmitted from the meter ECU (first control device) 101, and the CAN communication line 100A. And receiving setting information, the setting information is stored, and the operating state of the control operation for controlling the seat belt device 1 provided on the passenger seat side and the driver seat side is set according to the setting information. Note that the setting information is stored by updating the setting information received in the past with the newly received setting information.
Each of the passenger seat side seat belt ECU 102 and the driver seat side seat belt ECU 103 includes, for example, a winding position calculation unit 51, a control target setting unit 52, a motor control unit 53, and a transmission / reception unit 54. .

(First control device) 101 transmits / receives various information.

  For example, when the passenger seat side seat belt ECU 102 receives the setting information and the first identification information (for example, the identifier of DAT01) transmitted from the meter ECU (first control device) 101, it indicates that these pieces of information have been received. The first identification information reception information and the second identification information (for example, the identifier of DAT02) for identifying the passenger seat side seat belt ECU 102 are transmitted to the CAN communication line 100A.

  Further, for example, when the driver's seat side seat belt ECU 103 receives the setting information and the first identification information (for example, the identifier of DAT01) transmitted from the meter ECU (first control device) 101, it has received these information. And the third identification information for identifying the driver's seat side seat belt ECU 103 (for example, the identifier of DAT03) is transmitted to the CAN communication line 100A.

  When the passenger seat side seat belt ECU 102 receives the second identification information reception information transmitted from the driver seat side seat belt ECU 103 within a predetermined time after transmitting the first identification information reception information, the passenger seat side seat belt ECU 102 responds to the setting information. Setting completion information indicating that the setting of the operation state of the control operation has been completed is transmitted to the CAN communication line 100A. On the other hand, if the second identification information reception information transmitted from the driver seat side seat belt ECU 103 is not received within a predetermined time after the transmission of the first identification information reception information, the control operation according to the setting information is performed. The incomplete setting information indicating that the setting of the operation state is incomplete is transmitted to the CAN communication line 100A.

  When the driver seat side seat belt ECU 103 receives the first identification information reception information transmitted from the passenger seat side seat belt ECU 102 within a predetermined time after the transmission of the second identification information reception information, the driver seat side seat belt ECU 103 responds to the setting information. Setting completion information indicating that the setting of the operation state of the control operation has been completed is transmitted to the CAN communication line 100A. On the other hand, if the first identification information reception information transmitted from the passenger seat side seat belt ECU 102 is not received within a predetermined time after the transmission of the second identification information reception information, the control operation corresponding to the setting information is performed. The incomplete setting information indicating that the setting of the operation state is incomplete is transmitted to the CAN communication line 100A.

Further, for example, when the passenger seat side seat belt ECU 102 receives a signal indicating ignition ON from the ignition switch 61, the setting completion information indicating that the setting of the operation state of the control operation according to the setting information is completed and the passenger seat Second identification information (for example, an identifier of DAT02) for identifying the side seat belt ECU 102 is transmitted to the CAN communication line 100A.
Further, for example, when the driver's seat side seat belt ECU 103 receives a signal indicating that the ignition is on from the ignition switch 61, the setting completion information indicating that the setting of the operation state of the control operation according to the setting information has been completed and the driver's seat Third identification information (for example, an identifier of DAT03) for identifying the side seat belt ECU 103 is transmitted to the CAN communication line 100A.

  Upon reception of the setting completion information transmitted from the driver's seat side seat belt ECU 103, the passenger seat side seat belt ECU 102 performs control operation for controlling the seat belt device 1 in the passenger seat side seat belt ECU 102. It is determined whether the operating state (that is, the setting completion information transmitted together with the second identification information by the passenger seat side seat belt ECU 102) matches. When the determination result is “NO”, the operating state (that is, setting completion information) in the passenger seat side seat belt ECU 102 is initialized to a predetermined initial state.

  When the driver seat side seat belt ECU 103 receives the setting completion information transmitted from the passenger seat side seat belt ECU 102, the driver seat side seat belt ECU 103 performs control operation for controlling the seat belt device 1 in the driver seat side seat belt ECU 103. It is determined whether the operating state (that is, the setting completion information transmitted together with the third identification information by the driver seat side seat belt ECU 103) matches. When the determination result is “NO”, the operating state (that is, the setting completion information) in the driver seat side seat belt ECU 103 is initialized to a predetermined initial state.

  The data setting system 100 according to the present embodiment has the above-described configuration. Next, operations of the data setting system 100, particularly operations of the passenger seat side seat belt ECU 102 and the driver seat side seat belt ECU 103 will be described.

  Hereinafter, an operation at the time of customization for setting the operating state of the seat belt device 1 in accordance with an input operation by the operator to the operation unit 104 will be described.

First, for example, in step S01 shown in FIG. 6, setting information and first identification information (for example, an identifier of DAT01) transmitted from the meter ECU (first control device) 101 are received via the CAN communication line 100A. It is determined whether or not.
If this determination is “NO”, the flow proceeds to return.
On the other hand, if this determination is “YES”, the flow proceeds to step S 02.

Next, in step S02, “1” is set to self-bit which is data indicating whether or not the setting information and the first identification information are received.
Next, in step S03, reception information and identification information indicating that the setting information and the first identification information have been received are transmitted to CAN communication line 100A.
The reception information and the identification information are the first identification information reception information and the second identification information (for example, the identifier of DAT02) in the passenger seat side seat belt ECU 102, and the second identification information reception information in the driver seat side seat belt ECU 103. And third identification information (for example, an identifier of DAT03).

Next, in step S04, it is determined whether or not the reception information and identification information transmitted from another seat belt ECU are received within a predetermined time after the reception information and identification information are transmitted.
When the determination result is “NO”, the process proceeds to step S05, and in this step S05, data indicating whether or not reception information and identification information transmitted from other seat belt ECUs have been received. Set “0” to bit. Then, for example, as shown in FIG. 7, the setting incomplete information indicating that the setting of the operation state of the control operation according to the setting information is incomplete is transmitted to the CAN communication line 100A together with its own identification information, and the process returns. move on.
On the other hand, if this determination is “YES”, the flow proceeds to step S 06.

In step S06, “1” is set in cross-bit that is data indicating whether or not the reception information and the identification information transmitted from the other seat belt ECUs are received.
Next, in step S07, for example, as shown in FIG. 7, setting completion information indicating that the setting of the operation state of the control operation according to the setting information is completed is transmitted to the CAN communication line 100A together with its own identification information. Proceed to return.

  For example, in the setting completion information shown in FIG. 7, self-bit (Self), cross-bit (Cross), and customize-bit (Cust) that is data indicating whether the operating state of the seat belt device 1 is set. ) Is set to “1”, and in the setting incomplete information, “1” is set to self-bit (Self) and customize-bit (Cust), and “0” is set to cross-bit (Cross). Yes.

  Hereinafter, an operation in a state where setting information and first identification information (for example, the identifier of DAT01) are not transmitted from the meter ECU (first control device) 101, for example, when the vehicle is started will be described.

First, for example, in step S11 shown in FIG. 8, it is determined whether or not a signal indicating that the ignition is on has been received.
If this determination is “NO”, the flow proceeds to return.
On the other hand, if this determination is “YES”, the flow proceeds to step S12.

  Next, in step S12, if the setting information is already stored, “1” is set in the customize-bit (Cust), and the setting information is not yet stored (that is, the seat belt device 1). In the case where the operation state of the control operation for controlling the operation is a predetermined initial state), “0” is set in the customize-bit (Cust), and the setting completion information is transmitted to the CAN communication line 100A together with its own identification information. .

  For example, as shown in FIG. 9, in the setting completion information transmitted to the CAN communication line 100 </ b> A when the ignition is on, “0” is set in self-bit (Self) and cross-bit (Cross). If the setting information is not yet stored due to the replacement of the passenger side seat belt ECU 102 when the ignition is turned off, for example, as in the setting completion information of the passenger side seat belt ECU 102, the customize-bit (Cust ) Is set to “0”. On the other hand, when setting information is already stored, such as setting completion information of the driver's seat side seat belt ECU 103, “1” is set to customize-bit (Cust).

Next, in step S13, setting completion information and identification information transmitted from other seat belt ECUs are received.
Next, in step S14, it is determined whether or not the own setting completion information matches the setting completion information of the other seat belt ECU.
When the determination result is “YES”, the process proceeds to step S15, and in this step S15, the operating state of the control operation for controlling the seat belt device 1 is maintained, and the process proceeds to return.
On the other hand, if this determination is “NO”, for example, as shown in FIG. 9, if the customize-bit (Cust) is different between the passenger seat side seat belt ECU 102 and the driver seat side seat belt ECU 103, the process proceeds to step S16. move on.

  In step S16, if the operation state of the user is different from the predetermined initial state, the operation state of the user is initialized and the process proceeds to return. As a result, the operating state of the control operation for controlling the seat belt device 1 is initialized to a predetermined initial state. For example, as shown in the setting completion information of the driver seat side seat belt ECU 103 shown in FIG. 9, the customize-bit (Cust) Is set to “0”.

For example, as shown in FIG. 10, in the period from time t1 to time t2, a switch (for example, a meter switch) 111 that is linked to display on the liquid crystal display unit 113 provided in the meter panel 112 in the operation unit 104 is an operator. Is operated, the instruction signal instructing the operating state of various on-vehicle devices (for example, the seat belt device 1) is output.
Accordingly, at time t3 after a predetermined time (for example, 200 ms) from time t2, the operation of the in-vehicle device (for example, the seat belt device 1) is performed from the meter ECU (first control device) 101 according to the instruction signal. Setting information for setting the state and first identification information for identifying the meter ECU (first control device) 101 (for example, an identifier of DAT01) are output.

  Then, at time t4 after a predetermined time (for example, 200 ms) from time t3, each of the passenger side seat belt ECU 102 and the driver side seat belt ECU 103 that has received the setting information and the first identification information (for example, the identifier of DAT01). From the received information and identification information in which “1” is set in the self-bit, that is, the first identification information reception information and the second identification information (for example, the identifier of DAT02) of the passenger seat side seat belt ECU 102, and the driver seat side The second identification information reception information and the third identification information (for example, the identifier of DAT03) of the seat belt ECU 103 are output.

Then, at time t5 after a predetermined time from time t4, “1” is set in the cross-bit from each of the passenger seat side seat belt ECU 102 and the driver seat side seat belt ECU 103 that has received the reception information and the identification information. Setting completion information and identification information are output.
In addition, information on a predetermined meter identifier is output from the meter ECU (first control device) 101 over a period from time t5 to time t6.

As described above, according to the data setting system 100 according to the embodiment of the present invention, the meter ECU (first control device) 101 sets the setting completion information (or setting incomplete information) transmitted from the driver seat side seat belt ECU 103. Thus, in the passenger seat side seat belt ECU (second control device) 102 and the driver seat side seat belt ECU (third control device) 103, the setting of the operation state of the control operation according to the setting information is completed (or incomplete). Therefore, it is possible to simplify the control process without having to monitor the setting completion information and the setting incomplete information transmitted from the passenger seat side seat belt ECU (second control device) 102, for example. it can.
Further, the setting information transmitted from the meter ECU (first control device) 101 with the passenger seat side seat belt ECU (second control device) 102 and the driver seat side seat belt ECU 103 being the same, with a common configuration and control operation.
