    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 controlling apparatus includes an internal pressure detector for detecting an internal pressure of a combustion chamber of the engine. The apparatus estimates a motoring pressure of the engine and determines a start-of-combustion time, a time point when a difference between the internal pressure and the motoring pressure exceeds a predetermined value in a compression stroke and a combustion stroke of the engine. Firing delay for each cylinder is calculated from as a duration from sparking to the start-of-combustion time. Air-fuel ratio of each cylinder is estimated based on the firing delay and fuel injection amount for each cylinder is calculated to make the air-fuel ratio of plural cylinders uniform.

    摘要： An adsorbent state determining apparatus is provided for accurately determining the state of an adsorbent including a deterioration as well as for allowing for recovery of the adsorbent if its adsorbent performance can be restored. The adsorbent state determining apparatus determines the state of an adsorbent for adsorbing hydrocarbons contained in exhaust gases. An upstream and a downstream temperature sensor are provided at upstream and downstream locations of the adsorbent in an exhaust system for detecting temperatures of exhaust gases upstream and downstream of the adsorbent. An engine water temperature sensor detects an operating state of the engine. An ECU estimates the temperature of the exhaust gas which should be detected downstream of the adsorbent during adsorption of the adsorbent based on the upstream temperature detected by the upstream temperature sensor and an engine water temperature of the engine detected by the engine water temperature sensor. The ECU then compares the estimated downstream temperature with the detected downstream temperature detected by the downstream temperature sensor during adsorption of the adsorbent to determine the adsorption state of the adsorbent.
