摘要： A vehicle body slip angle-estimating device which, in estimating a vehicle body slip angle with an algorithm using a nonlinear model, is capable of accurately estimating a vehicle body slip angle irrespective of whether the frequency of occurrence of a state during traveling of the vehicle. A basic value-calculating section calculates a basic value of a vehicle body slip angle with an algorithm using a neural network model. A turning state-determining section determines whether the vehicle is in a predetermined limit turning traveling state. A correction value-calculating section calculates a correction value with an algorithm using a predetermined linear model when the vehicle is in the predetermined state. In the other cases, the correction value is set to 0. A straight traveling-determining section sets the angle to the sum of the basic value and the correction value when the vehicle is in a turning traveling state.

摘要： An ignition timing control system for an internal combustion engine, which is capable of properly carrying out ignition timing control over a wide control range, thereby making it possible to improve fuel economy, and is capable of suppressing combustion fluctuation, thereby making it possible to improve drivability. Ignition timing is calculated, when the engine is determined to be in an intense combustion mode, such that a largest in-cylinder pressure angle at which in-cylinder pressure becomes largest converges to a target angle, whereas when the engine is determined to be in a weak combustion mode, the same is calculated by feedback, based on the target angle and combustion state parameters indicative of a combustion state in the cylinder.

摘要： An air-fuel ratio control system for an internal combustion engine has a first air-fuel ratio sensor arranged in an exhaust passage at a location upstream of a catalyst and a second air-fuel ratio sensor arranged in the exhaust passage at a location downstream of the catalyst. In response to an output from the first air-fuel ratio sensor, an air-fuel ratio correction coefficient is calculated for correcting an amount of fuel supplied to the engine in a manner such that an air-fuel ratio of a mixture supplied to the engine is converged to a desired air-fuel ratio. In response to an output from the second air-fuel ratio sensor, a desired air-fuel ratio correction amount is calculated for correcting the desired air-fuel ratio. A learned value of the desired air-fuel ratio correction amount is calculated, and the desired air-fuel ratio is corrected. Calculation of the learned value of the desired air-fuel ratio correction amount is permitted depending on a ratio between a time period over which the output from the second air-fuel ratio sensor is on a richer side with respect to a predetermined reference value and a time period over which the output from the second air-fuel ratio sensor is on a leaner side with respect to the predetermined reference value.

The adaptive controller corrects the quantity of fuel injection to bring a controlled variable obtained at least based on an output of said air/fuel ratio sensor, to a desired value. The air/fuel ratio sensor outputs are sampled and one of the sampled data is selected as the air/fuel ratio to be input to the adaptation mechanism. Similarly, the senor outputs are sampled and one of the sampled is selected in accordance with another characteristic to be used in the estimation of the air/fuel ratios of the individual cylinder. The air/fuel ratio is discriminated to be within a prescribed range, and set to a predetermined value when it is determined to be within the prescribed range.

摘要： An ignition timing control system controls ignition timing of spark plugs of an internal combustion engine associated with a plurality of changeover devices, changeover of an operative state of each of which has influence upon output torque of the engine. Operating conditions of the engine are detected. A basic ignition timing advance value is calculated based on results of detection of the operating conditions of the engine. A changeover of the operative state of each of the changeover devices is detected. A correction value for correcting the basic ignition timing advance value for suppressing the engine torque is calculated, in response to results of detection of the changeover of the operative state of each of the changeover devices. The largest one of a plurality of the correction values calculated is selected to a final correction value to be used for correcting the basic ignition timing advance value, when changeovers of the operative states of at least two of the changeover devices are detected substantially at the same time.

摘要： An ignition timing control system for an internal combustion engine, which is capable of ensuring both stability of control in a steady operating condition of the engine, and an excellent follow-up property of a controlled variable to a target value in a transient operating condition of the engine, even when the controlled variable contains a lot of high-frequency noise components. In the ignition timing control system, a maximum pressure angle-calculating section calculates a maximum pressure angle based on an in-cylinder pressure and a crank angle position. A target angle-calculating section calculates a target angle. A maximum pressure angle controller calculates a maximum pressure angle correction term with a control algorithm to which is applied a sliding mode control algorithm, using a value obtained by performing ε-filtering on a switching function, such that the maximum pressure angle converges to the target angle. The ignition timing is calculated by adding corrected ignition timing to the value.
