Abstract: In an air-fuel ratio feedback control of an internal combustion engine aimed to approximate an air-fuel ratio to a target air-fuel ratio set according to operating conditions of the engine, the feedback control is carried out using the feedback control amount which is computed according to a sliding mode control, having a deviation between the target air-fuel ratio and the detected air-fuel ratio detected by the air-fuel ratio sensor set as a switching function. According to the present invention, a simple air-fuel ratio feedback control is carried out according to an accurate sliding mode control with no dispersion for each engine, that is easy to design, and that can be applied generally to any kind of vehicle or engine. Further, by varying the feedback gain depending on operating conditions, by controlling the computing cycle of the feedback control amount, or by performing a Smith dead time compensation control, the influence provided by the dead time element existing in the control object is eliminated, thereby ensuring the response characteristic and stability of the control system.

Abstract: An internal combustion engine having an intake passage that is closed at the time of engine starting operation wherein a holding time for completely closing a throttle valve is made as long as possible within such a range that the engine does not fail to be started. The throttle valve is held at its full-closure position when an ignition switch is turned on. Then, at the time of engine starting operation, an amount of air consumed by the engine is calculated based on a cumulative rotational speed of the engine, a cylinder volume of the engine, and a parameter of volumetric efficiency corresponding to an engine rotational speed, and, if so, the throttle valve is opened to a predetermined opening degree.

Abstract: The present invention relates to a circuit for processing internal combustion engine crank angle sensor signals. The construction is such that an output side circuit of a crank angle sensor outputs a crank angle signal with a high level pulse generated in response to the switching on and off of a switch element connected in series to a power source. Moreover, an input side circuit of a signal processing circuit includes a voltage reducing circuit which pulls down a power source voltage applied at the time of pulse generation, to a predetermined voltage and supplies this to an arithmetic processing section. Consequently, the output signal at the time of no pulse generation becomes a low level so that influence from noise is minimized. Also, since the input signal at the time of momentary disconnection of terminals connecting between the crank angle sensor and the processing circuit is a low level, then erroneous recognition of pulse generation is prevented. Moreover, since at the time of pulse generation, current flows between the terminals, then terminal oxidation film is removed so that poor contact can also be prevented.

Abstract: A plurality of lattice points arranged in a three-dimensional Cartesian coordinate system that takes first, second and third operating conditions as axes are associated in a one-to-one relationship with at least some of a plurality of cores arranged in a lattice shape in a multi-core processor, and a calculation program for calculating a control value at the associated lattice points is allocated to the cores. Each core with which a lattice point is associated is configured so that, in a case where an operation space on the three-dimensional Cartesian coordinate system to which a current operating point belongs is a space defined by eight adjacent lattice points including a lattice point associated with the relevant core, the relevant core calculates a control value at the lattice point associated therewith by means of the calculation program and sends the control value to an interpolation calculation core, and if the operation space is not defined by the eight adjacent lattice points, the relevant core suspends calculation of the control value. The interpolation calculation core performs an interpolation calculation to calculate a control value at the current operating point using control values at the eight adjacent lattice points surrounding the current operating point. The multi-core processor outputs a control value at the current operating point that is obtained by the interpolation calculation core as a control target value of an actuator.
