摘要： In a V-type six-cylinder engine, turbo-superchargers are provided for compressing intake air and feeding the compressed air into combustion chambers, and an ECU is operable to switch the combustion mode from a non-supercharged stoichiometric combustion mode to a supercharged lean combustion mode, depending on the engine operating conditions. When switching from the non-supercharged stoichiometric combustion mode to the supercharged lean combustion mode, the ECU retards the ignition timing, and keeps the retard amount of the ignition timing at a constant value if the increasing actual boost pressure becomes equal to or higher than a pre-set target boost pressure.

摘要： Hydraulic pressure control apparatus wherein a pressure difference across a seating valve disposed in a fluid passage acts on a valve member for placing the seating valve in an open state, while an elastic member biases the valve member for placing the seating valve in a closed state, and a valve driving device operated with an electric current applied thereto generates a drive force acting on the valve member so as to open the seating valve. A control device for controlling the electric current includes a stepping controller for incrementing the amount of the electric current when the seating valve is operated from the closed state into the open state, such that an increment of the electric current decreases with an increase in the pressure difference. The hydraulic pressure control apparatus may be suitably used in a vehicle braking system, for controlling fluid pressure in wheel brake cylinder.

摘要： Disclosed are a control device and a control method that are used with an internal combustion engine in which the air-fuel ratio in the vicinity of an ignition plug differs from the overall air-fuel ratio in a cylinder, and capable of properly fulfilling demands concerning various capabilities of the internal combustion engine by accurately reflecting each of the demands in the operation of each actuator. Three physical quantities, namely, a torque, an efficiency, and an air-fuel ratio, are used as controlled variables for the internal combustion engine. Target values for the controlled variables are then set by integrating at least some of demands concerning a capability of the internal combustion engine into the three physical quantities. Further, in accordance with the target values for the three controlled variables, namely, the torque, the efficiency, and the air-fuel ratio, three operation amounts, namely, an intake air amount adjustment valve opening, an ignition timing, and a fuel injection amount are set, and a fourth operation amount for adjusting the air-fuel ratio distribution in the cylinder is set.

摘要： An abnormality diagnosis system 100 includes a VVT controller 110, an adjustable valve mechanism 120, a cam angle sensor 130, a model computation module 140, an abnormality detection module 150, and an alarm lamp 160. The adjustable valve mechanism 120 advances or delays a phase angle of an intake cam shaft relative to a crankshaft, thereby varying an open-close timing of a valve. The model computation module 140 computes a physical behavior of the adjustable valve mechanism 120 according to a physical model, in response to a control signal input from the VVT controller 110. The abnormality detection module 150 determines whether the adjustable valve mechanism 120 is abnormal or normal, based on a difference between a theoretical value of phase angle calculated according to the physical model and an observed value of phase angle measured with the cam angle sensor 130. The arrangement of the invention ensures highly accurate abnormality diagnosis of the adjustable valve mechanism 120.

摘要： A required intake air flow rate is converted to a post-model required intake air flow rate (BMtsm) by a base-system normative model, and the inverse model of an intake system model is used to calculate a base-system required throttle opening degree (BTA) so as to achieve the post-model required intake air flow rate (BMtsm). On the other hand, the required in-take air flow rate (Mt) is converted to a post-model required intake air flow rate (HMtsm) by a high-response-system normative model, and the inverse model of the intake system model is used to calculate a high-response-system required throttle opening degree (HTA) so as to achieve the post-model required intake air flow rate (HMTsm). Then, a target throttle opening degree (TAt) is set so as to fall within the range from the base-system required throttle opening degree (BTA) to the high-response-system required throttle opening degree (HTA) and the reduce a variation amount.
