摘要： A control apparatus of a powertrain with a centrifugal pendulum absorber, includes an engine formed with a plurality of cylinders, a drive force transmission shaft for receiving an engine output torque, a centrifugal pendulum absorber for reducing a variation in the output torque, a connect-disconnect mechanism, an engine controlling module for shifting an engine operating state between an all-cylinder operation and a reduced-cylinder operation, and a connection controlling module. The connection controlling module shifts a connecting state of the connect-disconnect mechanism to a first state when the engine is in the all-cylinder operation, and shifts the connecting state to a second state in which the connection is tighter than the first state when the engine is in the reduced-cylinder operation. In response to issued requests to shift the engine operating state, the connection controlling module shifts the connecting state, and the engine controlling module shifts the engine operating state.

摘要： An engine includes a cylinder body, a cylinder head, and an ignition device including spark plugs. The engine also includes an intake device connected to intake ports, an exhaust device connected to exhaust ports, pistons, and a crankshaft connected to the pistons by connecting rods. Explosion intervals of the cylinders are 270°, 180°, 90°, and 180° as crank angles. The engine further includes a discomfort eliminator which, when the engine speed is lower than a predetermined value, makes the indicated mean effective pressure of at least one of two cylinders having an explosion interval of 90° lower than the indicated mean effective pressures of the other cylinders having an explosion interval of not 90°. The engine causes unequal-interval explosions but produces little change in the driving energy per unit time during an operating state in which an occupant is liable to feel torque fluctuations.

摘要： A control device for a hybrid vehicle is, in the process of stopping an internal combustion engine of the vehicle, capable of making twist angle fluctuation reduction control and crank angle position control mutually compatible. When a request for stopping the internal combustion engine has been issued, twist angle fluctuation reduction control is implemented without implementing crank angle position control, until, in the process of bringing the engine to a stopped state, the rotational speed of the internal combustion engine drops below the resonant rotational speed region of the torsional damper; and, after the rotational speed of the internal combustion engine has dropped below the resonant rotational speed region of the torsional damper in the process of bringing the engine to a stopped state, crank angle position control is implemented without implementing twist angle fluctuation reduction control, until stopping of the internal combustion engine has been completed.

摘要： A control device for an engine includes an accelerator opening detector for detecting an opening of an accelerator, a target acceleration setter for setting a target acceleration of a vehicle based on the accelerator opening detected by the accelerator opening detector, and an engine controller for adjusting an engine torque to achieve the target acceleration set by the target acceleration setter. When the accelerator opening is increased from a state where the target acceleration is set to zero, the target acceleration setter sets the target acceleration according to the accelerator opening to produce a highest jerk in the vehicle at an accelerator opening that is larger by 5 to 10% than an accelerator opening corresponding to the state where the target acceleration is set to zero.

摘要： In a vehicle control device, a dynamic characteristics description unit includes a model element simulating dynamic characteristics of motion or deformation of a controlled object. By using the model element, this unit simulates hysteresis characteristics caused during a process of motion or deformation of the controlled object based on at least one of an estimated value of the input manipulated variable and an estimated value of a disturbance input inputted in the controlled object, and defines a control target index of a motion state of the controlled object. A correction amount computing unit calculates a correction amount which adjusts the manipulated variable in such a way that the control target index related to the hysteresis characteristics becomes a desired state. A command output unit corrects manipulated variable based on the correction amount to produce a command for the corrected manipulated variable to output it to the controlled object.

摘要： A control system for an internal combustion engine, which controls an output torque of the internal combustion engine for driving a vehicle, is provided. An engine rotational speed is detected, and a change amount of the detected engine rotational speed is calculated. The output torque control amount of the engine is corrected so that the rotational speed change amount coincides with the center value of the local minimum value and the local maximum value of the rotational speed change amount. Specifically, a torque correction amount is calculated according to a torque value which is equal to half of a difference between peak vibration torque values corresponding to the local minimum value and the local maximum value of the rotational speed change amount, and an output torque control amount is corrected with the torque correction amount.
