- a part of the exhaust gas is recirculated as EGR gas from the downstream side of the turbine 12 to the upstream side of the compressor 11, and basically the EGR control valve 21 in a steady state.
- the EGR rate is determined by the valve opening (opening rate).
- the EGR control valve 21 when the intake air amount becomes larger than the predetermined amount Qlim1, the EGR control valve 21 only opens the EGR regardless of the intake air amount.
- the exhaust gas EGR gas
- the exhaust gas hardly circulates regardless of the valve opening degree of the EGR control valve 21, and the EGR rate becomes substantially zero.
- FIG. 2 schematically shows the correlation between the intake air amount and the EGR rate when the valve opening degree of the EGR control valve 21 is set to three different valve opening degrees (large, medium, and small).
- the EGR rate at the relatively largest valve opening among the three valve openings in FIG. 2 is a predetermined value at which the internal combustion engine 1 misfires when the intake air amount becomes larger than the predetermined amount Qlim1. It exceeds the misfire limit EGR rate.
- the EGR rate at the intermediate valve opening and the EGR rate at the relatively smallest valve opening are such that the intake air amount is greater than the predetermined amount Qlim1. Even if it becomes larger, it is smaller than the misfire limit EGR rate in the steady state.
- the EGR control valve 21 if the EGR rate when the intake air amount becomes larger than the predetermined amount Qlim1 with the fixed valve opening is equal to or greater than the misfire limit EGR rate, the intake air even in the steady state If the amount exceeds the predetermined amount Qlim1, the internal combustion engine 1 will misfire.
- the EGR control valve 21 when the EGR control valve 21 is fixed, the amount of exhaust gas recirculated to the intake passage 2 (EGR amount) is reduced by limiting the intake air amount, and the EGR rate of the internal combustion engine 1 is reduced. Is controlled so as not to exceed the misfire limit EGR rate even during deceleration.
- the upper limit of the intake air amount is set to the predetermined amount Qlim1.
- the intake air amount limit value Qlim is set to the predetermined amount Qlim1.
- the upper limit of the intake air amount is a predetermined amount Qlim2 (details will be described later) as a second predetermined amount.
- the limit value Qlim of the intake air amount is set to the predetermined amount Qlim2.
- valve opening threshold EGRVOth corresponds to a valve opening at which the EGR rate becomes the misfire limit EGR rate in a steady state when the intake air amount is larger than the predetermined amount Qlim1.
- the predetermined amount Qlim1 is set to a value that is slightly smaller than the intake air amount at which the EGR rate starts to rise sharply. This is to prevent the EGR rate from exceeding the misfire limit EGR rate even if the intake air amount exceeds the predetermined amount Qlim1 due to a slight fluctuation in a steady state.
- the predetermined amount Qlim2 is larger than the predetermined amount Qlim1, and is set to be smaller as the valve opening when the EGR control valve 21 is fixed is larger.
- This predetermined amount Qlim2 is calculated from a predetermined amount Qlim2 calculation table as shown in FIG. 3, for example, using the valve opening when the EGR control valve 21 is fixed.
- the EGR rate temporarily increases during deceleration, so the EGR rate during deceleration is Although the misfire limit EGR rate may become larger, the temporary increase amount of the EGR rate at the time of deceleration has a correlation with the change of the intake air amount, and becomes larger as the change of the intake air amount at the time of deceleration becomes larger. Tend to be.
- the predetermined amount Qlim2 in the present embodiment is set so that the larger the valve opening when the EGR control valve 21 is fixed, the smaller the valve opening when the EGR control valve 21 is fixed in consideration of a temporary increase in the EGR rate during the deceleration transition. Yes. That is, if the valve opening degree to which the EGR control valve 21 is fixed is a valve opening degree that is less than the misfire limit EGR rate in a steady state, the intake air is in accordance with the valve opening degree to which the EGR control valve 21 is fixed. Relax the amount limit.
- the predetermined amount Qlim2 is set to the maximum intake air amount of the internal combustion engine 1 when the valve opening to which the EGR control valve 21 is fixed is equal to or smaller than the first valve opening EGRVO1, which is a predetermined minute opening. . That is, if the valve opening when the EGR control valve 21 is fixed is a very small opening, the intake air amount is not substantially limited.
- the predetermined amount Qlim2 is smaller than the maximum intake air amount of the internal combustion engine 1. And it is set to become smaller as the fixed valve opening becomes larger. That is, when the valve opening when the EGR control valve 21 is fixed is larger than the first valve opening EGRVO1 and not more than the valve opening threshold EGRVOth, the intake air amount is limited.
- the predetermined amount Qlim1 and the predetermined amount Qlim2 are set on the premise of different situations as described above. Therefore, the valve opening to which the EGR control valve 21 is fixed is equal to the valve opening threshold value EGRVOth. Sometimes discontinuous.
- 4 and 5 are characteristic diagrams schematically showing changes in the EGR rate during deceleration when the limit value Qlim of the intake air amount is set to the predetermined amount Qlim2.

- the valve opening to which the EGR control valve 21 is fixed is the second valve opening EGRVO2
- the amount of intake air before deceleration is not so limited, and the amount of intake air before and after deceleration changes. Since it is large, the temporary increase amount of the EGR rate at the time of deceleration also increases, but since the original EGR rate is small, the misfire limit EGR rate is not exceeded.
- FIG. 5 shows a case where the valve opening degree to which the EGR control valve 21 is fixed is the third valve opening degree EGRVO3 closer to the valve opening degree threshold value EGRVOth than the first valve opening degree EGRVO1.
- the valve opening degree to which the EGR control valve 21 is fixed is the third valve opening degree EGRVO3
- the intake air amount (throttle valve opening) before deceleration is limited by the predetermined amount Qlim2, and the intake air before and after deceleration. Since the amount change is small, the temporary increase amount of the EGR rate at the time of deceleration is also small, and the misfire limit EGR rate is not exceeded.
- the EGR control valve 21 when the EGR control valve 21 is fixed, by limiting the intake air amount so that the internal combustion engine 1 does not misfire even during deceleration, misfire of the internal combustion engine 1 is prevented, and In addition, it is possible to prevent the internal combustion engine 1 from starting. Further, even if the EGR control valve 21 is fixed, the internal combustion engine 1 can be operated. Therefore, a vehicle using the internal combustion engine 1 as a drive source is safe to a maintenance shop or the like to repair the EGR control valve 21. Can self-propelled.
- the predetermined amount Qlim1 and the predetermined amount Qlim2 used for the intake air amount limit value Qlim are selectively used, so that the valve opening degree to which the EGR control valve 21 is fixed is obtained. If the valve opening is such that it becomes less than the misfire limit EGR rate in a steady state, the output of the internal combustion engine when the EGR control valve 21 is secured while preventing the misfire of the internal combustion engine due to the EGR control valve 21 being secured. Can be improved relatively. Therefore, the smaller the opening degree to which the EGR control valve 21 is fixed, the quicker it can go to a maintenance shop or the like in order to repair the fixing of the EGR control valve 21.
- the EGR control valve 21 When the EGR control valve 21 is fixed, for example, if a warning lamp or the like is turned on to notify the driver, it can be repaired at a maintenance shop or the like as soon as possible.
- FIG. 6 is a flowchart showing an example of a control flow for preventing the EGR rate from exceeding the misfire limit EGR rate even if the EGR control valve 21 is fixed.
- the control routine shown in FIG. 6 is executed in the control unit 25 every predetermined time, for example, during the operation of the internal combustion engine 1.
- the engine speed Ne of the internal combustion engine 1 and the valve opening EGRVO of the EGR control valve 21 are read.
- the engine speed Ne is calculated based on the output signal of the crank angle sensor 26 described above.
- the valve opening EGRVO is the valve opening of the EGR control valve 21 detected by the above-described EGR control valve opening sensor 28.
- S2 it is determined whether or not the EGR control valve 21 is fixed. For example, when the detected valve opening degree EGRVO deviates from the target EGR control valve opening degree and the detected valve opening degree EGRVO is unchanged for a predetermined time, the EGR control valve 21 is fixed. Is determined to be fixed. If it is determined that the EGR control valve 21 is fixed, the process proceeds to S3. If it is not fixed, the current routine is terminated.
- the limit value Qlim of the intake air amount is set to the predetermined amount Qlim1.
- the upper limit value of the intake air amount becomes the predetermined amount Qlim1.
- the predetermined amount Qlim2 is calculated based on the detected valve opening EGRVO of the EGR control valve 21.
- the predetermined amount Qlim2 is a value set so as to decrease as the valve opening degree to which the EGR control valve 21 is fixed increases.
- the predetermined amount Qlim2 is calculated as shown in FIG. It is calculated by storing the table in the control unit 25. Then, the process proceeds to S6, where the intake air amount limit value Qlim is set to the predetermined amount Qlim2.
- the target throttle valve opening tTVO set based on the depression amount of the accelerator pedal is compared with the throttle valve opening limit value TVOlim calculated in S7, and the target throttle valve opening tTVO is determined as the throttle valve opening.
- the target throttle valve opening degree tTVO is limited by the throttle valve opening degree limit value TVOlim.
- the throttle valve 5 is controlled using the throttle valve opening limit value TVOlim as the target throttle opening.
