Since the configuration of the third control device 30 is the same as that of the second control device 20, description thereof will be omitted.

  Next, processing of various devices included in the in-vehicle system according to Embodiment 1 of the present invention will be described. FIG. 4 is a flowchart showing an example of the electric load control process of the first control device 10 and the second control device 20 in the first embodiment of the present invention. When the operator (driver) of the driver's seat operates the operation unit 40, the operation unit 40 receives the operation, and first issues a control command that is a command for requesting control of various electric loads based on the received operation. Output to the control device 10. Here, it demonstrates as what performed operation which lights a headlight as an electrical load. The headlights are disposed as electric loads 10a and 20a on the left and right front sides of the vehicle 1, and must be turned on simultaneously by one operation. That is, synchronous control is required to control the electric load 10 a connected to the first control device 10 and the electric load 20 a connected to the second control device 20.

  The first control device 10 receives a control request from the operation unit 40 through the operation input circuit 11b (S101), transitions the control unit 11 and the communication control unit 12 to the operating state (S102), and the second control device 20 operates. It is detected whether or not it is in a state (S103). If the first control device 10 is already in an operating state when it receives a control request, the process of step S102 is omitted. The detection of whether or not the operation state is in step S103 is performed by determining whether or not an operation signal is received from the second control device 20.

  In step S103, when it is detected that the second control device 20 is not in the operating state but in the standby state (S103: NO), the first control device 10 transmits an operation command for transitioning from the standby state to the operating state. The data is transmitted from the unit 12 to the second control device 20 (S104).

  The second control device 20 receives the operation command (S105), and changes the control unit 21 and the communication control unit 22 from the standby state to the operation state based on the received operation command (S106).

  In addition, after transmitting the operation command, the first control device 10 detects whether or not the second control device 20 is in an operating state by the same method as in step S103 (S107).

  In step S107, when it determines with it being an operation state (S107: YES), the 1st control apparatus 10 gives the control command which controls the electric load 20a under control of the 2nd control apparatus 20 based on a control request. Then, the data is transmitted to the second control device 20 (S108), and the electric load 10a under its control is controlled based on the control request (S109). The control command transmitted in step S108 is a command to turn on the left headlight which is the electric load 20a, and the control in step S109 is a command to turn on the right headlight which is the electric load 10a. .

  The second control device 20 receives the control command (S110), and controls the electric load 20a under control based on the received control command (S111). That is, the second control device 20 turns on the left headlight.

  In step S103, when it is detected that the second control device 20 is in an operating state (S103: YES), the process proceeds to step S108, and the subsequent processing is executed.

  If it is determined in step S107 that the standby state is not the operation state (S107: NO), the first control device 10 waits for a predetermined time such as 1 millisecond (S112), returns to step S107, and the subsequent processing. repeat.

  In this way, the first control device 10 makes the second control device 20 transition to the operating state, and then controls the electric load 10a under its control and the electric load 20a under the control of the second control device 20. Therefore, the control of the operation of the electric load 10a and the electric load 20a can be performed synchronously.

  As shown in FIG. 5A, the operation unit 40 outputs a control request, and the first control device 10 that has received the input of the control request does not immediately control the electric load 10a after transition to the operating state. After confirming that the second control device 20 has transitioned to the operating state, the electric load 10a is controlled. Therefore, it is possible to synchronize the control of the electric load 10a by the first control device 10 and the control timing of the electric load 20a by the second control device 20.

  When the electric load control process according to the present invention is not applied, as shown in FIG. 5B, the first control device 10 that has received the input of the control request immediately changes to the second control device after the transition to the operating state. The control command is transmitted to 20 and the electric load 10a is controlled. However, since the second control device 20 requires time to transition from the standby state to the operating state, the timing of the control of the electric load 10a by the first control device 10 and the control of the electric load 20a by the second control device 20 are shifted. Specifically, after the right headlight is turned on, a phenomenon occurs in which the left headlight is turned on after a while.

  In the first embodiment, the mode for detecting whether or not the second control device is in the operating state by detecting whether or not the operating signal has been received has been shown, but the present invention is not limited to this, It is possible to develop in various forms such as detecting the state of the second control device by other methods.

The measurement of the operation time until the second control device 20 is activated is started (S201).

  After transmitting the operation command, the first control device 10 detects whether or not the second control device 20 is in an operating state (S202), and if it is determined that it is in an operating state (S202: YES), The measurement is stopped (S203), and the operation time obtained by the measurement is recorded in the control circuit 11a (S204).

  Then, the first control device 10 transmits a control command to the second control device 20 (S108), and executes the processing after step S108 of the electric load control processing of the first embodiment.

  If it is determined in step S202 that the operation is not the operation state but the standby state (S202: NO), the first control device 10 waits for a predetermined time such as 1 millisecond (S205), returns to step S202, and the subsequent processing. repeat.

  FIG. 7 is a flowchart illustrating an example of the electrical load control process of the first control device 10 according to the second embodiment of the present invention. The electrical load control process according to the second embodiment is a process executed after the operation time measurement process is executed and the operation time of the second control device 20 is recorded. The first control device 10 performs the processing of steps S101 to S104 of the electrical load control processing of the first embodiment described with reference to FIG. 4 and transmits an operation command (S104), and the operation of the second control device 20 is performed. A predetermined standby time set based on the time is waited (S301), and after the standby time has elapsed, a control command is transmitted to the second control device 20 (S108), and step S108 of the electrical load control process of the first embodiment is performed. The subsequent processing is executed. The predetermined standby time set based on the operation time of the second control device 20 in step S301 is a time set by adding a predetermined margin time to the recorded operation time measured in the operation time measurement process. By waiting for a predetermined waiting time, the first control device 10 synchronizes control of the electric load 10a and the electric load 20a without detecting whether or not the second control device is in an operating state. be able to.
