Abstract: A preparation control for suppressing fluctuation of an output torque of the engine at the time of executing switching operation from the whole cylinder operation to the partial cylinder operation is executed when having made a switching request from the whole cylinder operation to the partial cylinder operation, the valve operation phase is fixed to a predetermined phase before executing the switching operation, and the cylinder deactivation mechanism is controlled so as to execute the switching operation at a target switching time which is prefixed by corresponding to the predetermined phase. The target switching time is previously set to a timing at which abnormal noises are not generated, by corresponding to the valve operation phase fixed to the predetermined phase.

Abstract: A preparation control for suppressing fluctuation of an output torque of the engine at the time of executing switching operation from the whole cylinder operation to the partial cylinder operation is executed when having made a switching request from the whole cylinder operation to the partial cylinder operation. The target switching time executing the switching operation is calculated in accordance with the valve operation phase after the preparation time is completed. The cylinder deactivation mechanism is controlled such that the switching operation is executed at the target switching time. The target switching time is set in accordance with the valve operation phase at the timing in which the abnormal noises are not generated.

Abstract: In a malfunction judging method for a fuel feeding apparatus in an internal-combustion engine, a feedback correction value is calculated based on an air-fuel ratio parameter and a predetermined feedback control algorithm. In which region a load parameter exists among a first region in which only a first fuel feeding apparatus is used, a second region in which only a second fuel feeding apparatus is used, and a third region other than the first region and the second region is determined. The feedback correction value calculated in a case where the load parameter exists in the first region is determined as a first learned value using a predetermined first learning method. The feedback correction value calculated in a case where the load parameter exists in the second region is determined as a second learned value using a predetermined second learning method.

Abstract: A control device is provided capable of reliably preventing occurrence of a surging state by judging a possibility of the surging state in a relatively easy manner and promptly executing a surging state avoidance control. When a supercharging pressure decreasing state in which a target supercharging pressure decreases is detected, an operating speed of a wastegate valve is determined based on a detected engine rotational speed. That is, by lowering the operating speed as the engine rotational speed lowers, reduction in flow rate of the air passing through a compressor is prevented, and the occurrence of the surging state is reliably prevented. By lowering the operating speed instead of changing a target opening degree of the wastegate valve, a maximum opening degree of the wastegate valve can be suppressed, and responsiveness in the case where an acceleration request is made immediately after deceleration of an engine can be improved.

Abstract: A vehicle control device includes: a recognizer configured to recognize a surrounding situation of a host vehicle; an input unit configured to receive an input operation from an occupant of the host vehicle; a controller configured to perform automatic stop control of decelerating and stopping the host vehicle when the input operation is received by the input unit; and a setter configured to perform a setting process of setting a first time after the input operation has been received by the input unit and until the automatic stop control is started by the controller. The setter is configured to change the first time based on a result of recognition of a following vehicle of the host vehicle from the recognizer in the setting process.
