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.

摘要: A controller is provided, which detects operating conditions of an internal combustion engine on the basis of detection results from a group of sensors and drives an actuator that modifies an opening position of a wastegate valve on the basis of the operating conditions. When driving the wastegate valve to a fully closed opening, the controller initially drives the actuator toward a preset provisional fully closed position, and after determining on the basis of a detection result from a position sensor that an actual opening of the wastegate valve has reached the provisional fully closed opening, switches a target opening to the fully closed opening and drives the actuator accordingly.

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: An actuator control unit has a first pattern in which the energization phase is switched on every switching of pulse signals, and a second pattern in which, even when a switching timing of the energization phase due to the switching of the pulse signals exists, the energization phase is not switched during a predetermined period, and, in an acceleration period before a specific position in which the actual rotation angle position of the detent plate is going toward the target rotation angle position and then the rotation becomes stable, the energization phase is switched with the first pattern set, then, in a deceleration period after the specific position in which the rotation of the motor is stable and then the actual rotation angle position generally matches the target rotation angle position, the energization phase of the motor is switched with the second pattern set.

摘要: Provided are a wastegate valve control device for an internal combustion engine and a wastegate valve control method for an internal combustion engine, which are capable of controlling a wastegate valve (WGV) to a desired open/closed state at low cost even when a reference position of the WGV is shifted from a full-closure position of the WGV. When a target WGV opening (control target value) is equal to or smaller than a threshold opening, a given opening is added to or subtracted from the target WGV opening while the WGV is controlled to perform an opening/closing operation based on the target WGV opening. By monitoring a change in throttle upstream pressure or driving current of a WGV actuator, an optimal target WGV opening corresponding to the shift of the reference position with respect to the full-closure position of the WGV is determined.
