[1. First Embodiment]
[1-1. Constitution]
An engine control system 1 shown in FIG. 1 is a system mounted on a vehicle and controls the engine 14. The engine control system 1 includes an electronic control unit (hereinafter referred to as ECU) 13. ECU is an abbreviation for Electronic Control Unit. The engine control system 1 may include an accelerator sensor 11, a crank angle sensor 12, and an engine 14.

  In the present embodiment, the engine 14 is a diesel engine. The engine 14 burns a fuel / air mixture in a combustion chamber formed in a cylinder block (not shown), and generates power by reciprocating a piston in a cylinder (not shown).

The engine 14 includes an injector 41. The injector 41 injects fuel into the combustion chamber according to a control signal from the ECU 13.
Since the engine 14 is a diesel engine as described above, the engine 14 does not include an ignition circuit included in a gasoline engine. Here, the ignition circuit includes an igniter, an ignition coil, a spark plug, and the like, and generates a spark for burning a fuel / air mixture in accordance with a control signal from the ECU 13.

  The accelerator sensor 11 outputs a detection signal indicating the accelerator opening based on the depression amount of the accelerator pedal to the ECU 13. The crank angle sensor 12 outputs a detection signal indicating a rotation angle (hereinafter referred to as a crank angle) of a crankshaft included in the engine 14 to the ECU 13.

  The ECU 13 is configured around a known microcomputer (hereinafter referred to as a microcomputer 30) having a CPU 31 and a semiconductor memory (hereinafter referred to as a memory 32) such as a ROM 33, a RAM 34, and a flash memory 35. The ECU 13 may include a detection circuit 36 and a switch 37.

  The detection circuit 36 detects an on / off signal Ig which is a signal indicating that the ignition switch of the vehicle is turned on or off. However, the present invention is not limited to this, and the on / off signal Ig may be a signal indicating that the engine start button is turned on or off. When detecting the on / off signal Ig indicating that the ignition switch is turned on, the detection circuit 36 outputs a switch control signal SC for turning on the switch 37.

  Further, when detecting the on / off signal Ig indicating that the ignition switch is turned off, the detection circuit 36 outputs a switch control signal SC for turning off the switch 37. The switch 37 is switched on or off according to the switch control signal SC. The ECU 13 is configured to supply power to the microcomputer 30 from a battery BAT (not shown) when the switch 37 is turned on.

  Various functions of the ECU 13 are realized by the CPU 31 executing a program stored in a non-transitional physical recording medium. In this example, the ROM 33 corresponds to a non-transitional tangible recording medium that stores a program. Also, by executing this program, a method corresponding to the program is executed. The number of microcomputers 30 constituting the ECU 13 may be one or more.

  The method of realizing various functions of the ECU 13 is not limited to software, and some or all of the elements may be realized using one or a plurality of hardware. For example, when the above function is realized by an electronic circuit that is hardware, the electronic circuit may be realized by a digital circuit including a large number of logic circuits, an analog circuit, or a combination thereof.

  In the present embodiment, the ECU 13 acquires a detection signal indicating the accelerator opening from the accelerator sensor 11 by the CPU 31 executing a program. Further, a detection signal indicating the crank angle is acquired from the crank angle sensor 12. Moreover, ECU13 controls the injection quantity when the injector 41 injects fuel based on the detection signal acquired from each sensor.

  A program for acquiring an accelerator opening (hereinafter referred to as an accelerator opening acquiring program), a program for acquiring a crank angle (hereinafter referred to as a crank angle acquiring program), and a program for controlling an injection amount (hereinafter referred to as an injection amount control program) are basic software. (Hereinafter referred to as BSW) is recorded in the ROM 33 in advance, for example. BSW is an abbreviation for Basic Software.

  The BSW is a function program referred to in the claims, and is a program that realizes a predetermined function. BSW is a program used in at least one of a plurality of predetermined types of vehicles such as a first vehicle having a diesel engine and a second vehicle having a gasoline engine, as shown in FIG. is there.

  In a vehicle equipped with a gasoline engine, the ECU is generally configured to output a control signal to an ignition circuit in order to generate a spark when the CPU executes a program, and outputs the control signal to the ignition circuit. For this purpose (hereinafter referred to as an ignition circuit control program) is recorded in advance in the ROM 33 or the like. In vehicles equipped with a diesel engine, generally, an ignition circuit control program is not recorded in the ROM 33 or the like in advance.

  On the other hand, in the ECU 13 of this embodiment, each of the accelerator opening degree acquisition program, the crank angle acquisition program, the injection amount control program, and the ignition circuit control program is recorded in advance in the ROM 33 of the memory 32 as BSW. . The BSW may be recorded in the flash memory 35. The flash memory 35 is a rewritable memory such as an EEPROM, for example, and can retain the recorded contents even when the power supply is cut off.

The BSW group described later refers to a function program group referred to in the claims, and refers to the plurality of BSWs recorded in the memory 32.
In this way, the ECU 13 according to the present embodiment stores a program used in at least one of a plurality of vehicles having different specifications, such as a first vehicle having a diesel engine and a second vehicle having a gasoline engine. As a result, the program is shared. The commonality here means that the ECU 13 is preliminarily provided with a BSW for realizing a plurality or all of various functions provided in the vehicle.

  In addition, as shown in FIG. 2, the program comprised using BSW according to the specification of each vehicle among BSW groups is called the application program (henceforth, vehicle application) for the vehicle. Hereinafter, the accelerator opening degree acquisition program is described as BSW_A, the crank angle acquisition program as BSW_B, the injection amount control program as BSW_C, and the ignition circuit control program as BSW_D. The first vehicle application includes BSW_A to BSW_C, and the second vehicle application includes BSW_A to BSW_D.

  That is, in the present embodiment, as shown in FIG. 3, in the first vehicle, the BSW group and the first vehicle application are recorded in the memory 32 as the first vehicle software group. In the second vehicle, the BSW group and the second vehicle application are recorded in the memory 32 as the second vehicle software group.

[1-2. processing]
Next, application initialization processing executed by the CPU 31 in the ECU 13 will be described with reference to the flowchart of FIG. The application initialization process is a process for initializing the vehicle application when power supply to the ECU 13 is started. Here, the case where the power supply to the ECU 13 is started specifically means that the power supply to the microcomputer 30 of the ECU 13 is started.

  The ECU 13 performs an application initialization process when power supply to the ECU 13 is started. As described above, the ECU 13 determines that the power supply to the ECU 13 is started by the detection circuit 36 when the ignition switch of the vehicle is turned on or the engine start button is pressed. That is, the ECU 13 determines that the power supply is started when the power supply to the vehicle on which the ECU 13 is mounted is started.

  In the present embodiment, the ECU 13 is configured to start power supply to peripheral circuits of the CPU 31 such as a communication circuit when power supply to the ECU 13 is started. Further, the detection circuit 36 is configured to be constantly supplied with power.

  In S10 to S30, the ECU 13 sequentially initializes the BSW used in the vehicle on which the ECU 13 is mounted. That is, the ECU 13 sequentially performs initialization for all the BSWs used in the ECU 13 in the BSW group. Specifically, the ECU 13 sequentially executes initialization processing predetermined for each BSW.

  In the initialization process, the BSW is initialized, and usage information indicating that the initialized BSW is a used BSW is recorded in the memory 32. The used BSW is a BSW used in the ECU 13 in the BSW group.

  The term “initialization” as used herein means that various processes required in advance for executing a program such as a vehicle application or BSW are performed. For example, the initialization may include setting various parameter values used in the BSW to initial values. The parameters here may include, for example, variables used for various calculations that are set to 0 by initialization, predetermined values that are set to predetermined values by initialization, and the like. Further, for example, the initialization can include a process of securing an area of the memory 32 necessary for executing the program.

In the present embodiment, since the engine 14 is a diesel engine, the ECU 13 does not execute the initialization process of BSW_D.
In S10, the ECU 13 executes a BSW_A initialization process. Next, in S20, the ECU 13 executes a BSW_B initialization process. Subsequently, in S30, the ECU 13 executes a BSW_C initialization process. Then, the process proceeds to S40.

  If the ECU 13 is mounted on a second vehicle having a gasoline engine, the ECU 13 executes the BSW_D initialization process in S30 after the BSW_C initialization process in the application initialization process. To S40.

  In S40, the ECU 13 executes unused processing. In the unused process, an unused BSW in the BSW group is specified, and the operation of the actuator to be controlled by the unused BSW is stopped. The unused BSW is a BSW other than the used BSW in the BSW group. The unused processing will be described later. After executing the unused process, the ECU 13 ends the application initialization process.

  Next, the initialization process for each BSW executed in S10 to S30 in the application initialization process will be described. Here, since the same process is performed for each BSW, the BSW_A initialization process, which is the initialization process for BSW_A, will be described with reference to the flowchart of FIG.

In S110, the ECU 13 initializes the BSW. Here, BSW_A is initialized.
Next, in S120, the ECU 13 records the usage information in the memory 32. The usage information is information indicating that the initialized BSW is the usage BSW. In the present embodiment, for each BSW of the BSW group, an area for recording a flag indicating whether or not the BSW is used (hereinafter referred to as a use flag) is previously defined in the memory 32. The use flag is reset in the initial state, and the ECU 13 sets the use flag when the BSW is initialized in S110. That is, in S120, the ECU 13 sets a use flag for BSW_A and ends the BSW_A initialization process.

  In this way, in the application initialization process, the use flag is set for the BSW that is initialized in the BSW group. The use flag is recorded in the flash memory 35. Note that the use flag for each BSW of the BSW group corresponds to the use information.

Next, the unused process executed in S40 in the application initialization process will be described with reference to the flowchart of FIG.
In step S210, the ECU 13 acquires usage information. In other words. The ECU 13 acquires a use flag for each BSW of the BSW group from the memory 32.

  In S220, the ECU 13 acquires correspondence information. As shown in FIG. 7, for example, the correspondence information represents a correspondence relationship between each BSW of the BSW group and an actuator to be controlled by the BSW. The correspondence information is recorded in advance in the ROM 33 of the memory 32.

  In S230 to S250, the ECU 13 sequentially determines whether or not the BSW is the used BSW for each BSW of the BSW group, and stops the operation of the actuator to be controlled by the BSW when the BSW is not the used BSW. Process.

  That is, in S230, the ECU 13 determines whether or not the BSW is a use BSW based on the use flag. The ECU 13 shifts the process to S250 when the BSW is a used BSW, and shifts the process to S240 when the BSW is an unused BSW.

  In S240, when the unused BSW is specified based on the usage information, the actuator to be controlled by the unused BSW is specified based on the correspondence information, and the operation of the actuator is stopped. Stopping the operation means disabling the operation, and may include, for example, stopping the power supply. The ECU 13 stops the operation of the actuator to be controlled by the unused BSW, and then shifts the process to S250.

  In S250, the ECU 13 determines whether or not all BSWs in the BSW group have been determined to be used BSWs. If the ECU 13 has not made a determination for all BSWs in the BSW group, the ECU 13 shifts the process to S230 and repeats the processes of S230 to S250. When the ECU 13 determines all the BSWs in the BSW group, the ECU 13 ends the unused process.

  The operation by the application initialization process described above will be described. In this embodiment, when power supply to the ECU 13 is started, initialization processing is performed for BSW_A to BSW_C other than BSW_D in the BSW group, the usage flags of BSW_A to BSW_C are set in the usage information, and the usage BSW is Identified. Further, based on the usage information, BSW_D in which the usage flag remains reset is identified as an unused BSW. Then, power supply to the ignition circuit to be controlled by BSW_D is stopped.

  In the present embodiment, for example, a program for executing the application initialization process corresponds to the aforementioned vehicle application, more specifically, the first vehicle application. In addition, each of BSW_A, BSW_B, BSW_C, BSW_D, and a program for executing an initialization process for each BSW predetermined for each BSW and a program for executing an unused process correspond to the BSW.

[1-3. effect]
According to the first embodiment described in detail above, the following effects are obtained.
(1a) The ECU 13 is mounted on the vehicle. The ECU 13 determines whether or not the detection circuit 36 has started power supply to the ECU 13. In S10 to S30, when power supply is started, the BSW used in the ECU 13 in the BSW group is initialized, and the usage information indicating that the initialized BSW is the used BSW is stored in the memory 32. Let me record. The BSW group includes a plurality of predetermined BSWs. The BSW is a program that is recorded in advance in the memory 32, is used in at least one of a plurality of predetermined types of vehicles, and realizes a predetermined function. The used BSW is a BSW used in the ECU 13 in the BSW group.

  When power supply to the ECU 13 is started, all BSWs used in the ECU 13 or many, if not all, BSWs are generally initialized. In particular, in this embodiment, when the power supply to the ECU 13 is started, all BSWs used in the ECU 13 are initialized.

  According to this, since it has the structure which records the usage information showing that BSW initialized at the time of a power supply start is use BSW, BSW currently used in the vehicle can be specified. As a result, the BSW that is not used in the vehicle in the BSW group can be specified, and the processing load by the ECU 13 and the power consumption in the vehicle can be reduced.

  Incidentally, in recent years, a development environment has arisen in which vehicle applications and BSW are developed by different developers. Developers here may include people and companies. That is, in the present embodiment, all of the BSW group or at least a part of the BSW group may be a program developed by a developer different from the vehicle application. The vehicle application is a program including at least one BSW.

  A developer of a vehicle application develops a vehicle application for each vehicle by using a combination of BSWs appropriately selected based on specifications required for each vehicle from the BSW group. For this reason, although the developer of the vehicle application can specify the type of BSW used in the vehicle application, it is difficult for the developer of the BSW to specify the type of BSW used in the vehicle application. There was a problem that there was.

  That is, since it was difficult for a BSW developer to specify an unused BSW, it was difficult to develop a new program using the existing BSW as a new BSW. The new program using the existing BSW may include, for example, a program that reduces the processing load by calling only the used BSW and not calling the unused BSW. In addition, a program for reducing power consumption by driving an actuator to be controlled by a used BSW and stopping an actuator to be controlled by an unused BSW can be included.

  As described above, it has been desired to develop a technique for identifying the BSW used in the vehicle application without obtaining information on the BSW used in the vehicle application from the developer of the vehicle application.

  According to this embodiment, since the BSW initialized at the start of power supply to the ECU 13 is recorded in the usage information as the usage BSW, the BSW developer specifies the usage BSW based on the usage information. Can do. As a result, the BSW developer can develop various programs without obtaining information about the BSW used in the vehicle application from the developer of the vehicle application.

(1b) In S10 to S30, the ECU 13 initializes all BSWs used in the ECU 13 in the BSW group.
According to this, since the use flag as the usage information is recorded for all the BSWs used in the ECU 13 at the start of power supply, all the BSWs used in the vehicle on which the ECU 13 is mounted are based on the usage information. Can be specified.

(1c) In S230, the ECU 13 acquires correspondence information representing the correspondence between each BSW of the BSW group and the actuator to be controlled by the BSW.
According to this, the actuator to be controlled by the used BSW or the unused BSW is specified based on the correspondence information. That is, in a vehicle equipped with the ECU 13, an actuator that is used or an actuator that is not used can be specified.

  (1d) In S240, the ECU 13 specifies an unused BSW based on the usage information, specifies an actuator to be controlled by the unused BSW based on the correspondence information, and stops the operation of the specified actuator. The unused BSW is a BSW other than the used BSW in the BSW group.

  According to this, since an actuator that is not used is identified and the operation of the actuator is stopped, the actuator is not used even after all the actuators to be controlled by the BSW group are driven at the start of power supply. The operation of the actuator to be controlled by the BSW can be stopped. As a result, power consumption in the ECU 13 can be reduced.

[2. Second Embodiment]
[2-1. Difference from the first embodiment]
Since the basic configuration of the second embodiment is the same as that of the first embodiment, differences will be described below. Note that the same reference numerals as those in the first embodiment indicate the same configuration, and the preceding description is referred to.

  In the first embodiment described above, the unused process is executed in S40 in the application initialization process. On the other hand, the second embodiment differs from the first embodiment in that unused processing is deleted in S40 and driving processing is added in S5.

[2-2. processing]
Next, an application initialization process executed by the ECU 13 of the second embodiment instead of the application initialization process of the first embodiment shown in FIG. 4 will be described with reference to the flowchart of FIG. Note that the processing of S10 to S30 in FIG. 8 is the same as the processing of S10 to S30 in FIG.

  In S5, the ECU 13 executes a driving process. The driving process drives at least a part of all the actuators to be controlled by the BSW group when power supply to the ECU 13 is started. Note that all actuators are actuators to be controlled by all the BSWs in the BSW group. Further, at least a part of all actuators means an actuator to be controlled by at least a part of BSWs in the BSW group.

The driving process will be described later. The ECU 13 shifts the process to S10 after executing the drive process.
ECU13 performs the process similar to FIG. 4 in S10-S30. ECU13 complete | finishes this application initialization process, after performing the process of S30.

Next, the drive process executed by the ECU 13 in S5 will be described using the flowchart of FIG.
In step S310, the ECU 13 acquires usage information from the memory 32.

In S320, the ECU 13 acquires correspondence information from the memory 32.
In S330, the ECU 13 determines whether or not the power supply to the ECU 13 is the first time. The first power supply here means that the ignition switch is turned on for the first time after the vehicle equipped with the ECU 13 is shipped, or the start button is pressed for the first time.

  Specifically, the ECU 13 determines whether or not power supply to the ECU 13 is started for the first time based on whether or not the usage information is recorded in the memory. As described above, in the usage information, in the initial state, the usage flag for each BSW of the BSW group is reset. The ECU 13 determines that the start of power supply to the ECU 13 is the first time when all the usage flags are reset in the usage information.

The ECU 13 shifts the process to S340 when the power supply to the ECU 13 is started for the first time, and shifts the process to S350 when it is not the first time.
The ECU 13 drives all the actuators to be controlled by the BSW group in S340 that is shifted to when it is determined that the start of power supply is the first time. And ECU13 complete | finishes this drive process. Driving here means supplying power.

  In S350 that is shifted to when it is determined that the power supply is not the first time, the ECU 13 specifies the actuator to be controlled by the use BSW based on the use information and the correspondence information, and drives the actuator. And ECU13 does not drive actuators other than the actuator used as control object. The actuators other than the actuators to be controlled refer to the remaining actuators excluding the actuators to be controlled by the used BSW among all the actuators to be controlled by the BSW group.

  That is, the ECU 13 stops the operation of the actuator to be controlled by the unused BSW when the power supply to the ECU 13 is the second time or later. Then, the driving process ends.

[2-3. effect]
According to 2nd Embodiment explained in full detail above, there exist the effect (1a)-(1c) of 1st Embodiment mentioned above, and also there exist the following effects.

  (2a) In S5, when power supply is started, the ECU 13 drives at least a part of all actuators to be controlled by the BSW group. In S10 to S30, the ECU 13 is configured to initialize the BSW and record the usage information in the memory after driving the actuator in S5. In S430, the ECU 13 determines that the power supply to the ECU 13 is the first time when the usage information is not recorded in the memory, based on whether the usage information is recorded in the memory.

  In S440, the ECU 13 drives all the actuators to be controlled by the BSW group when it is determined that power supply is the first time. When it is determined in S450 that the power supply is not the first time, the ECU 13 specifies the actuator to be controlled by the use BSW based on the usage information and the correspondence information, drives the actuator to be controlled, and controls the control target. Do not drive any actuator other than the actuator.

  According to this, after the usage information is recorded in the memory 32, the used BSW is initialized without driving the actuator corresponding to the unused BSW. For this reason, for example, every time power is supplied, the processing load is higher than that of the comparative example in which all the actuators to be controlled by the BSW group are driven and then the operation of the actuator to be controlled by the unused BSW is stopped. Can be reduced.

[3. Third Embodiment]
In the third embodiment, the ECU 13 may be configured to execute the periodic process shown in FIG. 10 after the usage information is recorded in the memory 32.

[3-1. processing]
The periodic process is a process that is repeatedly executed at a predetermined cycle. The predetermined cycle here may include a cycle in which a crank angle having a predetermined magnitude is acquired, for example, every 6 ° CA, every 10 ° CA, or the like. CA is a crank angle and is an abbreviation for Crank Angle.

In step S410, the ECU 13 acquires usage information from the memory 32.
In S420, the ECU 13 determines whether each BSW group is a use BSW based on the use information acquired in S410.

In S430, the ECU 13 executes the BSW determined to be the used BSW, and shifts the process to S450.
In S440, the ECU 13 shifts the process to S450 without executing the BSW that was not determined to be the used BSW.

  In S450, the ECU 13 determines whether or not all the BSWs in the BSW group have been determined to be used BSWs. The ECU 13 repeats the processes of S220 to S250 when not determining all the BSWs. When the ECU 13 determines all the BSWs, the ECU 13 ends the regular process.

[3-2. effect]
According to the third embodiment described in detail above, the effects (1a) to (1d) and (2a) of the first embodiment described above are exhibited, and the following effects are further achieved.

  (3a) In S410, the ECU 13 acquires usage information for each predetermined period. In S420, the ECU 13 determines whether each BSW group is a use BSW based on the use information acquired in S410. In S440, the ECU 13 executes the BSW determined to be the used BSW in the BSW group, and does not execute the BSW that is not determined to be the used BSW, that is, the unused BSW.

  According to this, even if a program that sequentially executes a plurality of BSWs including unused BSWs is executed as a periodic program that operates at predetermined intervals, the unused BSWs are not executed. An excessive processing load can be reduced.

[4. Other Embodiments]
As mentioned above, although embodiment of this indication was described, this indication is not limited to the above-mentioned embodiment, and can carry out various modifications.

(4a) In the above embodiment, the ECU 13 is an electronic control device for controlling the engine 14, and the engine control system 1 includes the accelerator sensor 11 and the crank angle sensor 12. However, the present invention is limited to this. It is not a thing. The engine control system 1 may include various sensors that detect information for controlling the engine 14. Examples of the sensor may include an air flow meter, an intake pressure sensor, an intake air temperature sensor, and an O ₂ sensor. In addition, a program for acquiring various information detected by these sensors can be included in the BSW. A program for performing various controls for driving the engine 14 based on these various types of information can be included in the BSW.

  The ECU 13 can be an electronic control device for realizing various functions in the vehicle. That is, the BSW is not limited to a program that controls the engine control system 1. The BSW can include various programs for realizing any predetermined function in the vehicle.
