The control unit 10 sequentially executes the operations shown in the flowchart of FIG. 3 for the communication devices 2b and 2c while the engine is operating. Then, the control unit 10 periodically and repeatedly executes a series of operations performed on the communication devices 2a, 2b, and 2c.
The interval at which the control unit 10 repeatedly executes a series of operations may not be regular.

  Next, an example of contents stored in the storage unit 17 will be described. FIG. 4 is an explanatory diagram showing the contents stored in the storage unit 17. Here, the IDs of the communication devices 2a, 2b, and 2c are ID-A, ID-B, and ID-C, respectively. For each ID, the storage unit 17 stores a detection result, a previous detection result, information indicating the date and time and the position of the vehicle, and information regarding the remaining battery level.

  The communication device whose ID is ID-A, that is, the communication device 2a is in the vehicle in the latest detection result, and information indicating that it is in the vehicle in the previous detection result is stored in the storage unit 17. Yes. Further, since the latest detection result is stored in the vehicle, it is determined whether or not the remaining battery level of the communication device 2a is equal to or less than a predetermined value, and the remaining battery level of the communication device 2a is low. The determination result is stored.

  Information indicating that the communication device whose ID is ID-B, that is, the communication device 2b is not in the vehicle in the latest detection result and is in the vehicle in the previous detection result is stored in the storage unit 17. ing. Since the detection result stored in the storage unit 17 is changed from the information indicating that the detection result is present in the vehicle to the information indicating that the detection result is not present in the vehicle, the date and time when the detection result indicating that the detection result is not present in the vehicle is stored. Is stored. Further, it is determined whether or not a determination result indicating that the remaining amount of the battery is low is stored when the detection result indicating that the vehicle is in the vehicle is stored.

  As a result, the date and time when the detection result indicating that the communication device 2b is not in the vehicle is stored is XX day △ △ hour □ □ minute, the position of the vehicle at that time is XX city, and the battery has run out. Information indicating that there is a possibility that it is detected that the vehicle is not in the vehicle is stored.

  Information indicating that the communication device whose ID is ID-C, that is, the communication device 2c is not in the vehicle in the latest detection result and the previous detection result is stored in the storage unit 17.

  The content stored in the storage unit 17 illustrated in FIG. 4 is an example, and the content stored in the storage unit 17 is not limited to the content illustrated in FIG. Furthermore, the contents stored in the storage unit 17 other than the IDs and detection results of the communication devices 2a, 2b, and 2c are not limited to information indicating the date and time and the position of the vehicle, and information related to the remaining battery level. Further, the content stored by the storage unit 17 other than the detection result may be any one or two of information indicating the date and time, information indicating the position of the vehicle, and information regarding the remaining amount of the battery.

  Next, an operation procedure executed by the control unit 10 of the vehicle engine control apparatus 1 when the reception unit 11 receives an operation for stopping the engine will be described. The engine is started by the engine control unit 12 after the receiving unit 11 receives an operation for starting the engine.

  FIG. 5 is a flowchart showing a procedure of operations performed by the control unit 10 when the receiving unit 11 receives an operation for stopping the engine. First, the control unit 10 determines whether or not the receiving unit 11 has received an operation for forcibly stopping the engine (step S51). Here, the reception unit 11 measures a period during which the switch is pressed and turned on when receiving an operation for forcibly stopping the engine by pressing and holding the switch for a few seconds. The reception unit 11 determines whether an operation for stopping the engine or an operation for forcibly stopping the engine is received depending on whether the measured time exceeds several seconds, and notifies the control unit 10 of the determination result. .

  When it is determined that the reception unit 11 has not received an operation for forcibly stopping the engine (step S51: NO), the control unit 10 determines whether the reception unit 11 has received an operation for stopping the engine. (Step S52). When it is determined that the receiving unit 11 has not received an operation for stopping the engine (step S52: NO), the control unit 10 returns to step S51.

  When the control unit 10 determines that the operation of stopping the engine is received by the reception unit 11 (step S52: YES), the latest detection results of the communication devices 2a, 2b, and 2c stored in the storage unit 17 (FIG. 4) (step S53).

  Next, the control unit 10 determines whether or not at least one of the communication devices 2a, 2b, and 2c is in the vehicle based on the detection result referred to in step S53 (step S54).

  When it is determined that the receiving unit 11 has received an operation for forcibly stopping the engine (step S51: YES), or when at least one of the communication devices 2a, 2b, and 2c is present in the vehicle, the control unit 10 When it determines (step S54: YES), the engine control part 12 is made to stop an engine (step S55). The control unit 10 ends the operation after executing Step S55.

  When it is determined that the communication devices 2a, 2b, and 2c are not all in the vehicle (step S54: NO), the control unit 10 does not instruct the engine control unit 12 to stop the engine and prohibits the engine from being stopped ( Step S56).

  Next, the control unit 10 causes the display unit 18 to display the contents stored in the storage unit 17, for example, the explanatory diagram shown in FIG. 4 (step S57). Accordingly, the driver can notice that the engine cannot be stopped because the communication devices 2a, 2b, and 2c are taken out of the vehicle.

Further, since the driver can know the date and time when the communication devices 2a, 2b, and 2c disappear from the vehicle and the position of the vehicle, the driver can estimate the positions of the communication devices 2a, 2b, and 2c. Further, since the possibility of running out of the battery is also displayed, the driver can know the possibility that the communication devices 2a, 2b, 2c were not detected due to running out of the battery.
The control unit 10 ends the operation after executing Step S57.

  In the present embodiment, whether or not any of the communication devices 2a, 2b, and 2c is in the vehicle while the engine is operating is periodically detected by the control unit 10 and detected. The result is stored in the storage unit 17. When the driver performs an operation to stop the engine while all the communication devices 2a, 2b, and 2c are taken out while the engine is operating, the storage unit 17 stores all the communication devices 2a, 2b, and 2c in the vehicle. The engine is prohibited from being stopped. Therefore, even after an operation for stopping the engine is performed in the above-described situation, the engine does not stop, so that the driver can drive the vehicle.

  When the driver performs an operation to stop the engine, the control unit 10 refers to the detection result stored in the storage unit 17 and permits or prohibits the engine stop based on the referred detection result. Therefore, the vehicle engine control device 1 does not need to communicate with the communication devices 2a, 2b, and 2c in order to check the ID every time the receiving unit 11 receives an operation for stopping the engine. Thereby, the time from when the reception unit 11 receives an operation for stopping the engine until the engine control unit 12 stops the engine is short, and the driver is not uncomfortable.

  In the present embodiment, display unit 18 displays a determination result indicating that the remaining battery level is less than or equal to a predetermined value and the remaining battery level is low for each of communication devices 2a, 2b, and 2c. For this reason, it is possible to inform the driver that the remaining battery level is low, to prompt the driver to replace the battery, and to prevent a situation in which the communication devices 2a, 2b, 2c cannot be detected due to running out of the battery. Can do.

  In the present embodiment, the engine can be forcibly stopped even when the engine is prohibited from being stopped. For this reason, after realizing that the engine is prohibited from being stopped, the driver may stop the engine by moving the vehicle to an appropriate place such as a parking lot or a road shoulder that does not obstruct the passage of the vehicle. It becomes possible.

  In the present embodiment, as shown in FIG. 5, when the receiving unit 11 receives an operation for stopping the engine, the control unit 10 refers to the detection result stored in the storage unit 17 and refers to the engine result. It is determined whether or not to stop the operation. However, the control unit 10 stores the operation procedure shown in the flowchart of FIG. 3 in the storage unit 17 every time a series of operations performed on the communication devices 2a, 2b, and 2c is finished while the engine is operating. Whether the engine stop is permitted or prohibited may be determined by referring to the detection result.

  In this case, the control unit 10 stores the determination result in the storage unit 17. When the receiving unit 11 receives an operation to stop the engine, if the determination result that the storage unit 17 permits the engine to stop is stored, the control unit 10 stops the engine, and the storage unit When the determination result 17 indicates that the engine stop is prohibited, the engine stop is prohibited.

  In the present embodiment, the number of communication devices is not limited to three. The number of communication devices may be 1, 2 or 4 or more. In addition, when it is stored that all the communication devices 2a, 2b, and 2c are not in the vehicle, a series of operations that the control unit 10 sequentially executes for each of the communication devices 2a, 2b, and 2c while the engine is operating. You may lengthen the period which repeats.

  The disclosed embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
