Description

The present invention relates to an in-vehicle engine control device that controls idling stop of an engine mounted on a vehicle.

Vehicles in which idling stop control is performed for the purpose of reducing engine fuel efficiency are known. In the idling stop control, the engine operation is automatically stopped when a predetermined automatic stop condition is satisfied during idle operation. Further, if a predetermined automatic restart condition is satisfied during the automatic stop of the engine, the engine is automatically restarted. The "automatic stop" and "automatic restart" of the engine in the idling stop control are terms to distinguish from the normal "operation stop" and "operation start" of the engine.

As an engine control device that performs the idling stop control, for example, there is one described in Patent Document 1. With this control device, the engine automatically restarts when the driver's door is switched from the closed state to the open state or the driver's seat belt is switched from the attached state to the non-attached state while the engine is automatically stopped. Will be done.

JP-A-2015-214936

However, even if the driver's door is switched to the closed state again after the engine is automatically restarted, or even if the driver's seat belt is switched to the wearing state again, after the vehicle speed exceeds a predetermined value. If certain conditions are not met, the automatic stop will not be performed again and fuel efficiency will deteriorate. For example, this is the case when the vehicle continues to stop after the automatic restart of the engine.

On the other hand, if the automatic stop of the engine is permitted only on the condition that the driver's door is switched to the closed state after the automatic restart of the engine, the driver is not seated in the driver's seat. The engine may stop automatically.

The vehicle-mounted engine control device that solves the above problems is the vehicle-mounted engine control device that controls the idling stop of the engine mounted on the vehicle, provided that the driver's seat door of the vehicle is closed at least. The engine automatic stop unit that automatically stops the engine and the engine automatic restart unit that automatically restarts the engine when the driver's seat door is switched to the open state during the automatic stop of the engine by the engine automatic stop unit. The engine automatic stop unit is provided with a predetermined vehicle interior equipment in which the driver's seat door is switched to the closed state after the automatic restart in response to the switch to the open state of the driver's seat door. The engine is automatically stopped, at least on condition that it is operated.

According to the above configuration, in the idling stop control, the engine automatic stop unit automatically stops the engine when the driver's door of the vehicle is closed, at least on condition of that. Further, the engine automatic restart unit automatically restarts the engine when the driver's door is switched to the open state during the automatic stop.

Here, when the driver's door is switched to the closed state and the vehicle interior equipment is operated after the automatic restart corresponding to the switch to the driver's door open state, the driver sits in the driver's seat. It is possible that there is.

In this regard, according to the above configuration, the engine automatic stop unit is a vehicle in which the driver's door is switched to the closed state and the driver's door is switched to the closed state after the automatic restart corresponding to the switch to the open state of the driver's door. The engine is automatically stopped, at least on condition that the interior equipment is operated. Therefore, after the automatic restart of the engine, the fuel efficiency is improved as compared with the case where the automatic stop is not performed again under the situation where the driver may be seated in the driver's seat as described above.

Further, when the driver's door is switched to the closed state after the automatic restart corresponding to the switch to the driver's door open state, even if the conditions such as the vehicle speed exceeding a predetermined value are not satisfied, for example, the vehicle. It is possible to automatically stop the engine even if the door continues to stop.

Further, according to the above configuration, the engine is automatically stopped, at least on condition that the driver's door is switched to the closed state after the engine is automatically restarted and the vehicle interior equipment is operated. Therefore, it is less likely that the engine is automatically stopped even though the driver is not seated in the driver's seat, as compared with the case where the engine is automatically stopped only on the condition that the driver's door is switched to the closed state.

In the in-vehicle engine control device, the engine automatic stop unit automatically stops the engine when the window of the driver's door in the closed state is open, as compared with the case where the window is closed. It is preferable to limit the types of the vehicle interior equipment to be operated at the time.

Here, when the window of the driver's door in the closed state is open, there is a possibility that a hand is put into the vehicle interior through the open portion of the window from the outside of the vehicle to operate the vehicle interior equipment.
On the other hand, equipment inside the vehicle that is difficult to operate from outside the vehicle when the window of the driver's door in the closed state is open is operated from outside the vehicle when the window of the driver's door in the closed state is closed. Included in vehicle interior equipment that cannot be. Moreover, the types of vehicle interior equipment that are difficult to operate from outside the vehicle when the driver's door window in the closed state is open are those that cannot be operated from outside the vehicle when the window is closed. Less than the type of.

In this regard, according to the above configuration, the engine automatic stop unit is an operation for automatically stopping the engine when the window of the driver's door in the closed state is open, as compared with the case where the window is closed. Limit the types of vehicle interior equipment that are subject to. When a restricted type of vehicle interior equipment is operated, it is highly likely that the operation is not an operation from outside the vehicle but an operation by a driver seated in the driver's seat inside the vehicle interior.

Therefore, by making it a condition for the engine to automatically stop that the restricted types of interior equipment as described above are operated when the window of the driver's door in the closed state is open, the driver It is possible to automatically stop the engine only if it is more likely that the driver is seated in the driver's seat.

In the in-vehicle engine control device, in the engine automatic restart unit, the driver's seat door is closed and the driver's seat belt is not fastened while the engine is automatically stopped by the engine automatic stop unit. The engine is automatically restarted when the engine is switched to the mounted state, and the engine automatic stop unit is in the driver's seat while the engine is being driven after the automatic restart in response to the switch to the non-fastened state of the driver's seat belt. It is preferable to automatically stop the engine, at least on condition that the closed state of the door is kept.

Here, if the driver's seat belt is switched from the attached state to the non-attached state when the driver's door is closed during the automatic stop of the engine, it is assumed that the driver is seated in the driver's seat. Conceivable.

In this regard, according to the above configuration, the engine automatic restart unit can switch the driver's seat belt from the attached state to the non-attached state even when the driver's door is closed while the engine is automatically stopped. , Automatically restart the engine.

If the driver's door continues to be closed while the engine is being driven after the automatic restart, it is considered that the driver is still seated (not disembarked). In this regard, the engine automatic stop unit operates the engine at least on condition that the driver's seat door is kept closed while the engine is being driven after the automatic restart in response to the switching to the non-fastened state of the driver's seat belt. Automatically stop.

In this way, even when the engine is automatically started by switching the driver's seat belt to the non-fastened state, the engine is automatically stopped. Therefore, it is possible to improve the fuel efficiency as compared with the case where the engine is not automatically stopped under the above circumstances.

The vehicle interior equipment B is operated by putting a hand into the vehicle interior from outside the vehicle through the open portion 17 of the window 16 when the driver's door 15 is closed and the window 16 of the driver's door 15 is open. It is a difficult equipment to do.

The vehicle interior equipment B is included in the vehicle interior equipment A. Further, the type of the vehicle interior equipment B is smaller than the type of the vehicle interior equipment A by the amount of the vehicle interior equipment that can be operated by putting a hand into the vehicle interior through the open portion 17 of the window 16 from the outside of the vehicle.

Examples of the vehicle interior equipment B include the following.
-Switches that adjust the position of the seat-Switches on the passenger compartment side of the driver's seat door 15-Switches built into the instrument panel-Switches built into the steering wheel-Switches such as lights and wipers-The above Switches in the vehicle interior other than the above-Steering wheel-Sun visor-Vanity mirror The equipment operation state detection unit 25 is provided for each of the illustrated vehicle interior equipment B.

The belt wearing state detection unit 21, the door open / close state detection unit 22, the window open / close state detection unit 23, and the equipment operation state detection units 24 and 25 described above are connected to the control device 31, respectively, and the detected signal is output to the control device 31. Output to.

The control device 31 is a circuit including one or more processors that operate according to a computer program (software), one or more dedicated hardware circuits that execute at least a part of various processes, or a combination thereof. It is configured as. The control device 31 includes an engine automatic stop unit 32 and an engine automatic restart unit 33.

The engine automatic stop unit 32 automatically stops the engine 11 on condition that the automatic stop condition is satisfied. In addition to the above, the automatic stop condition includes that the driver's door 15 is in the closed state. The automatic stop is performed by the engine automatic stop unit 32 issuing a command to the fuel injection valve to stop the fuel injection (fuel cut).

The engine automatic restart unit 33 automatically restarts the engine 11 when the above automatic restart condition is basically satisfied during the automatic stop of the engine 11 by the engine automatic stop unit 32. This automatic restart is performed by the engine automatic restart unit 33 issuing a command to the fuel injection valve and the starter motor to start fuel injection and operate the starter motor. That is, the crankshaft is rotationally driven to perform cranking. During the cranking, fuel injection from the fuel injection valve is started. Then, when the injected fuel is ignited by the spark plug, the fuel is burned and the operation of the engine 11 is restarted.

In this embodiment, the following items are added to the automatic restart conditions.
-The driver's door 15 was switched to the open state while the engine 11 was automatically stopped.
-During the automatic stop of the engine 11, the driver's seat belt 14 was switched from the attached state to the non-attached state even if the driver's door 15 was not switched to the open state.

Further, in the present embodiment, the sitting situation (possibility) of the driver after the automatic restart of the engine 11 is determined, and the engine 11 is automatically stopped according to the determination result.
Next, the operation of the idling stop device 12 will be described as the operation of the present embodiment. The flowchart of FIG. 2 shows the processing performed by the engine automatic restart unit 33 of the control device 31.

The engine automatic restart unit 33 first determines in step 101 whether the engine 11 is automatically stopped. Here, the automatic stop of the engine 11 means that the engine 11 is automatically stopped by the engine automatic stop unit 32 based on the establishment of the automatic stop condition.

If the engine 11 is not automatically stopped (step 101: NO), the processing of this flowchart is temporarily terminated. On the other hand, when the engine 11 is automatically stopped (step 101: YES), the process proceeds to step 102.

In step 102, it is determined whether or not the driver's door 15 is in the open state based on the detection result of the door open / closed state detection unit 22. When the driver's door 15 is in the open state (step 102: YES), it is assumed that the automatic restart condition is satisfied, and the engine 11 is automatically restarted in step 103.

Then, in step 104, the engine 11 is driven. In step 105, it is determined whether or not the driver's door 15 is in the open state based on the detection result of the door open / closed state detection unit 22. When the driver's door 15 is in the open state (step 105: YES), the process returns to step 104. Therefore, the driving of the engine 11 is continued. On the other hand, when the driver's door 15 is closed (step 105: NO), is the window 16 of the driver's door 15 opened based on the detection result of the window open / closed state detection unit 23 in step 106? Judge whether or not.

When the window 16 is opened (step 106: YES), it is determined in step 107 whether or not the vehicle interior equipment B has been operated based on the detection result of the equipment operation state detection unit 25. As described above, the vehicle interior equipment B is equipment that is difficult to operate by putting a hand into the vehicle interior through the open portion 17 of the window 16 from the outside of the vehicle. On the other hand, the vehicle interior equipment A is equipment that cannot be operated from outside the vehicle and is operated by an occupant in the vehicle interior. The equipment that is the target of the vehicle interior equipment B is included in the equipment that is the target of the vehicle interior equipment A. Moreover, the types of equipment targeted by the vehicle interior equipment B are smaller than the types of equipment targeted by the vehicle interior equipment A. In other words, the various equipment listed as the vehicle interior equipment B is more restricted than the various equipment listed as the vehicle interior equipment A.

When the restricted type of vehicle interior equipment B is operated (step 107: YES), the operation may be performed by the driver seated in the driver's seat 13 in the vehicle interior, not from the outside of the vehicle. Is high. In this case, it is determined in step 108 whether other automatic stop conditions are satisfied.

If the other automatic stop conditions are not satisfied (step 108: NO), it is assumed that the engine 11 is not in a situation of automatic stop, and the process returns to step 104. On the other hand, when other automatic stop conditions are satisfied (step 108: YES), the processing of this flowchart is temporarily terminated. In this case, the engine 11 is automatically stopped by the engine automatic stop unit 32. On the other hand, if the vehicle interior equipment B is not operated (step 107: NO), the process returns to step 104.

On the other hand, in step 106, when the window 16 of the driver's door 15 in the closed state is closed (step 106: NO), the process proceeds to step 109. In step 109, it is determined whether or not the vehicle interior equipment A has been operated based on the detection result of the equipment operation state detection unit 24. When the vehicle interior equipment A is operated (step 109: YES), the driver may be seated in the driver's seat 13. In this case, the process proceeds to step 108. On the other hand, if the vehicle interior equipment A is not operated (step 109: NO), the process proceeds to step 107. That is, there is a possibility that the vehicle interior equipment B may be operated even if the vehicle interior equipment A is not operated while the window 16 of the driver's seat door 15 in the closed state is closed, so that the determination in step 107 is performed. Will be.

By the way, in step 102, when the driver's door 15 is in the closed state (step 102: NO), the process proceeds to step 110. In step 110, it is determined whether or not the driver's seat belt 14 has been switched from the wearing state to the non-wearing state based on the detection result of the belt wearing state detecting unit 21. If the driver's seatbelt 14 is not fastened (step 110: NO), that is, if the driver's seatbelt 14 is fastened, the engine 11 is not automatically restarted. The process is terminated once. On the other hand, when the driver's seat belt 14 is switched to the non-fastened state (step 110: YES), it is assumed that the automatic restart condition is satisfied, and the engine 11 is automatically restarted in step 111.

Then, in step 112, the engine 11 is driven. In step 113, it is determined whether or not the driver's door 15 is in the open state based on the detection result of the door open / closed state detection unit 22. When the driver's door 15 is in the open state (step 113: YES), the process proceeds to step 104. On the other hand, when the driver's door 15 is in the closed state (step 113: NO), the process proceeds to step 114.

In step 114, it is determined whether or not other automatic stop conditions are satisfied. When other automatic stop conditions are satisfied (step 114: YES), the processing of this flowchart is temporarily terminated. On the other hand, if the automatic stop condition is not satisfied (step 114: NO), the process returns to step 112.

According to the above flowchart, the following effects can be obtained.
(1) When the driver's door 15 in the open state is switched to the closed state and the vehicle interior equipments A and B are operated after the automatic restart of the engine 11, the driver is seated in the driver's seat 13. It seems possible.

In this respect, in the present embodiment, after the engine 11 is automatically restarted (steps 103 and 104), the driver's door 15 is switched from the open state (step 102) to the closed state, and the vehicle interior equipments A and B are operated. The engine 11 is automatically stopped (step 105 → 106 → 109 (and / or 107) → 108 → return) on condition that the engine 11 is automatically stopped. Therefore, after the automatic restart of the engine 11, the fuel efficiency is improved as compared with the case where the automatic stop is not performed again under the situation where the driver may be seated in the driver's seat 13 as described above.

As described above, according to the present embodiment, it is possible to improve the fuel efficiency of the engine 11 by automatically stopping the engine 11 according to the seating condition of the driver.
Further, when the driver's door 15 is switched to the closed state after the automatic restart of the engine 11, even if the conditions such as the vehicle speed exceeding a predetermined value are not satisfied, for example, even if the vehicle 10 continues to stop. The engine 11 can be automatically stopped.

Further, in the present embodiment, the engine 11 is automatically stopped, at least on condition that the driver's door 15 is switched to the closed state after the automatic restart of the engine 11 and the vehicle interior equipments A and B are operated. Will be done. Therefore, the engine 11 may be automatically stopped even though the driver is not seated in the driver's seat 13, as compared with the case where the engine 11 is automatically stopped only on the condition that the driver's door 15 is switched to the closed state. It's hard to happen.

(2) When the window 16 of the driver's seat door 15 in the closed state is open, there is a possibility that a hand is put into the vehicle interior through the open portion 17 of the window 16 from the outside of the vehicle to operate the vehicle interior equipment.
On the other hand, vehicle interior equipment that is difficult to operate from outside the vehicle when the window 16 of the driver's door 15 in the closed state is open cannot be operated from outside the vehicle when the window 16 is closed. Included in indoor equipment. Moreover, the types of vehicle interior equipment that are difficult to operate from outside the vehicle when the window 16 of the driver's door 15 in the closed state is open cannot be operated from outside the vehicle when the window 16 is closed. Less than the types of interior equipment.

In this respect, in the present embodiment, as the vehicle interior equipment A, equipment that cannot be operated from outside the vehicle and is operated by an occupant in the vehicle interior is defined. As the vehicle interior equipment B, equipment that is difficult to operate by putting a hand into the vehicle interior through the open portion 17 of the window 16 from the outside of the vehicle is specified.

In the above flowchart, it is determined whether or not the vehicle interior equipment B is operated when the window 16 of the driver's seat door 15 in the closed state is opened. When the vehicle interior equipment B is operated while the window 16 of the driver's door 15 in the closed state is open (step 107: YES), other automatic stop conditions are satisfied (step 108: YES). ), The engine 11 is automatically stopped.

By doing so, when the window 16 of the driver's door 15 in the closed state is open, the interior of the vehicle which is the target of the operation for automatically stopping the engine 11 is compared with the case where the window 16 is closed. The types of equipment are limited. When the restricted type of vehicle interior equipment B is operated, it is highly possible that the operation is not an operation from outside the vehicle but an operation by a driver seated in the driver's seat 13 in the vehicle interior.

Therefore, when the window 16 of the driver's seat door 15 in the closed state is open, the condition for the automatic stop of the engine 11 is that the vehicle interior equipment B of the type restricted as described above is operated. The engine 11 can be automatically stopped only when the driver is more likely to be seated in the driver's seat 13.

(3) If the driver's seat belt 14 is switched from the attached state to the non-attached state when the driver's door 15 is closed while the engine 11 is automatically stopped, the driver sits in the driver's seat 13. It is thought that it is.

In this respect, in the present embodiment, even if the driver's seat door 15 is in the closed state during the automatic stop of the engine 11, when the driver's seat belt 14 is switched from the attached state to the non-attached state, the engine 11 is operated. It automatically restarts (step 101 → 102 → 110 → 111).

Further, if the driver's door 15 continues to be closed while the engine is being driven after the automatic restart, it is considered that the driver is still seated (not disembarked).
In this respect, in the present embodiment, the engine is operated at least on condition that the driver's seat door 15 is continuously closed while the engine is being driven after the automatic restart in response to the switching of the driver's seat belt 14 to the non-fastened state. 11 is automatically stopped (step 112 → 113 → 114 → return).

In this way, even when the engine 11 is automatically started by switching the driver's seat belt 14 to the non-fastened state, the engine 11 is automatically stopped. Therefore, the fuel efficiency can be improved as compared with the case where the engine 11 is not automatically stopped under the above circumstances.

It should be noted that the above embodiment can also be implemented as a modified example in which this is modified as follows. The above embodiment and the following modifications can be implemented in combination with each other within a technically consistent range.

-In the flowchart of FIG. 2, the history of the operation status of the vehicle interior equipment A may be stored, and the determination in step 109 may be performed based on the history. Similarly, the history of the operation status of the vehicle interior equipment B may be stored, and the determination in step 107 may be performed based on the history. In both cases of steps 109 and 107, it is assumed that the determination condition is satisfied when there is a history.

-In the flowchart of FIG. 2, a determination time may be set for each determination, and when the target state continues for the determination time, it may be determined that the determination condition is satisfied. For example, in steps 102, 105, and 113, if the driver's door 15 has been open for the above determination time, it may be determined that the determination condition is satisfied. The same applies to the determination of whether or not the window 16 is opened in step 106 and the determination of the operating state of the vehicle interior equipments A and B in steps 109 and 107.

-In the flowchart of FIG. 2, in step 109, it may be considered that the determination condition is satisfied when one vehicle interior equipment A is operated, or the determination is made when a plurality of vehicle interior equipment A are operated. It may be said that the conditions are met. The same applies to the operation of the vehicle interior equipment B in step 107.

-In the flowchart of FIG. 2, the process of step 107 may be omitted as appropriate. In this case, if the determination condition of step 106 is satisfied, the process proceeds to step 104. The same applies when the determination condition of step 109 is not satisfied, and the process proceeds to step 104.

-In the flowchart of FIG. 2, the processing of steps 111, 112, 113, 114 may be omitted as appropriate. In this case, if the determination condition of step 110 is satisfied, the process proceeds to step 103.
