摘要： In a control device for an internal combustion engine, when a target pre/post compressor pressure ratio calculated by a target pre/post compressor pressure ratio calculation part is more than a turbine-limit-time pre/post compressor pressure ratio calculated by a turbine-limit-time pre/post compressor pressure ratio calculation part, an upper limit of the target pre/post compressor pressure ratio is limited by the turbine-limit-time pre/post compressor pressure ratio, and a change rate of the target pre/post compressor pressure ratio is limited by a change rate limit value during a change rate limitation period after upper limit limitation processing starts, thereby preventing the target pre/post compressor pressure ratio from being suddenly fluctuated by a sudden fluctuation in a compressor passage flow rate, and suppressing the occurrence of the over rotation of the turbine and the control hunting.

摘要： The present invention provides a controller and a control method for an internal combustion engine, which can suppress the generation of an annoying collision noise and abnormal heating of a motor of an actuator, which are generated by contact of the output shaft of the actuator with an opening side stopper of the actuator. The controller and the control method for the internal combustion engine are configured such that a target opening (Sv) of the valve is set to the smaller of: a required target opening (Sv_dem) computed so that a target supercharging pressure (Sp) and an actual supercharging pressure (Pp) are matched with each other; and a restricted target opening (Sv_lmt) computed based on a fully closed position learning value (Pv_lrn), which corresponds to an actual position detected by a position sensor, when the valve is located in the fully closed position, and on the restricted target position.

摘要： While an actuator is driven by an actuator driving unit with an operation amount for which the maximum value is limited by an operation amount limitation unit, if a state in which the actual opening degree of a wastegate valve does not coincide with a target opening degree has continued for a predetermined time period, driving by the actuator driving unit is attempted with an operation amount for which the maximum value limitation is relaxed by an operation amount limitation relaxing unit. Even after this, if the state in which the actual opening degree of the wastegate valve does not coincide with the target opening degree still has not been eliminated, an abnormality determination unit determines that abnormality has occurred in an opening degree control system for the wastegate valve.

摘要： Supply a control device for an internal combustion engine in which an abnormality of an exhaust-bypass valve, such as a WGV, can be certainly detected under wide operation conditions. In the control device, a required-operation position of the exhaust-bypass valve, which is set in accordance with an operating condition of the internal combustion engine, is set to a target position, and an exhaust-bypass-valve-driving device is controlled in such a way that a real position, which is detected by a position sensor, agrees with the target position, and when a real position, which is detected by a position sensor, reaches a predetermined abnormality-judgment value, it is judged that an abnormality is caused in a mechanical-connecting condition from the exhaust-bypass valve to the exhaust-bypass-valve-driving device.

摘要： Provided is a control device for an internal combustion engine, which is configured to: acquire an internal combustion engine required opening degree of the waste gate valve based on the operation state of the internal combustion engine. When the internal combustion engine required opening degree is full closing, full closing learning control is carried out by converting the target opening degree of the waste gate valve to a target opening degree for full closing learning so as to bring about a state in which the waste gate valve fully closes the exhaust bypass passage. When a state in which the position of the actuator does not change consequently continues for a set period, it is considered that the fully closed state is brought about and the full closing learning is finished, and a correction amount for the feedback control is decreased.

摘要： A controller, for a supercharger-equipped internal combustion engine, that can improve the feedback response of compressor driving force is provided. In a controller, inertial force produced by an inertial moment of a supercharger is calculated, based on a real rotation speed of the supercharger; then, driving force feedback control is implemented in which a gate valve control value, which is a control value for a gate valve actuator, is changed so that an addition value obtained by adding the inertial force to the real compressor driving force approaches a target compressor driving force.
