摘要： An engine control unit includes pressure detector provided in a combustion chamber of the engine. A motoring pressure of the engine is estimated. A combustion starting time is detected when the difference between an internal pressure detected by the pressure detector and the pressure estimated by the ECU exceeds a predetermined value. When the internal pressure detected by the pressure detector reaches its peak after the combustion starting time has been detected, the crank angle at this time point is determined to correspond to the maximum internal cylinder pressure that is generated by combustion.

摘要： An in-cylinder pressure detection device for an internal combustion engine, which is capable of detecting an in-cylinder pressure accurately without being adversely affected by changes in the atmospheric pressure even when the atmospheric pressure changes. An in-cylinder pressure sensor detects pressure within a cylinder as a detected in-cylinder pressure. An ECU estimates pressure generated in the cylinder during a non-combustion period as a motoring pressure. An atmospheric pressure sensor detects an atmospheric pressure (PA). The ECU corrects the motoring pressure according to the atmospheric pressure and identifies correction parameters such that the difference between the detected in-cylinder pressure detected during a compression stroke of the engine and the corrected motoring pressure becomes minimum, and corrects the detected in-cylinder pressure by the identified correction parameters, to thereby calculate an in-cylinder pressure.

The ignition timing control apparatus comprising an ECU. The ECU determines a basic ignition timing on a cylinder-by-cylinder basis, calculates a knock intensity on a cylinder-by-cylinder bases based on a detected signal of a cylinder inner pressure sensor, and updates a correction coefficient learning value for a corresponding cylinder when the knock intensity is larger than a predetermined first determination value and is smaller than a predetermined second determination value larger than the predetermined first determination value, and updates the knock intensities for all the cylinders when the one knock intensity parameter is equal to or larger than the predetermined second determination value. Then, the ECU calculates a knock correction term on a cylinder-by-cylinder basis in accordance with the correction coefficient learning value, and corrects the basic ignition timing with the knock correction term, thereby determining an ignition timing on a cylinder-by-cylinder basis.

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.
