摘要:
An engine control apparatus comprises: an actual control condition detector for detecting an actual control condition of an engine; an adjusting device for adjusting the actual control condition of the engine; and a controller for controlling the adjusting device such that the actual control condition of the engine is controlled to a target control condition using a state variable amount and a feedback constant determined on the basis of a dynamic model of the engine, wherein the controller has: a predicated control condition operation circuit for operating a predicted control condition on the basis of the dynamic model of the engine; a deviation operation circuit for operating a deviation of the predicated control condition from the target control condition; a changing circuit for changing control of the controller such that fluctuations of the control condition become small in accordance with a judgement made such that an error of the dynamic model exceeds a tolerance when the deviation exceeds a predetermined value. According to this invention, there is an advantage effect that fluctuation of the engine speed is suppressed because of prevention of hunting due to reduction of variation in the control amount.

The present invention pertains to a method for producing a mixture including an injected engine fuel from an injector, a combustion engine intake-air and an evaporative gas from the engine fuel. The method includes the steps of measuring a characteristic of the evaporative gas and changing step for changing a mixing ratio of the evaporative gas to at least one of the injected engine fuel and the combustion engine intake-air, according to the measured characteristic of the evaporative gas, by changing a flow rate of the combustion engine intake-air.

In a remote operation system in which an in-vehicle unit is controlled by an operation command transmitted from a portable unit carried by a driver via a service center, when the vehicle receives an operation command B for controlling the in-vehicle unit from a second state to a first state, the operation command B is executed only when control based on an operation command A for controlling from the first state to the second state is made.

A robot apparatus which, by exploiting limited resources highly efficiently, is capable of making expressions matched to the motion or to complex variegated feeling or instinct states, representing the crucial information in achieving smooth communication with the human being, is disclosed. A method of expression by the robot apparatus is also disclosed. The robot apparatus expresses plural states, such as emotional states or the processing states of perceptual recognition, by a light radiating device loaded at a location of the head part of the humanoid robot apparatus walking on two legs. The light radiating device includes e.g. the color hue, saturation and patterns of light emission as expressive units represented independently of one another. A plural number of orthogonal states, that is, the emotional states and the states of perceptual recognition, are expressed simultaneously, using a plural number of the orthogonal representations of the light radiating device correlated by a unit for correlating plural reciprocally orthogonal states, derived from the own inner states or external stimuli, with at least one expressive unit.

A disk playback device has a front panel pivoted at a lower end thereof to a lower end portion of an open front side of a cabinet, and a slide panel movable into and out of the cabinet along guide slots in the opposite side walls of the cabinet. The slide panel has a fitting pin and a slide pin projecting from each side face thereof and fitting respectively in an elongated hole in each of the side walls of the front panel and in the guide slots of each cabinet side wall. The slide panel is slidable along the guide slots with the opening and closing of the front panel. When the front panel is in a completely opened position, the fitting pin is positioned at a lower level than the guide slot, and the slide panel is exposed inclinedly from the cabinet with a recessed surface which receives the disk facing upwardly.

摘要:
An air-fuel ratio control apparatus constructed, in an engine of a type storing evaporated fuel generated in a fuel tank in a canister and thereafter drawing off the evaporated fuel to an intake side of an engine through a bleedoff passage, so as to inhibit renewal of an air-fuel ratio learning value when the evaporated fuel concentration is at a predetermined value or higher in case of learning and renewal of an air-fuel ratio in order to make feedback control of the air-fuel ratio of an air-fuel mixture supplied to the engine. In an apparatus which adsorbs evaporated fuel generated in a fuel tank in a canister and purges the evaporated fuel adsorbed in the canister to an intake side of an internal combustion engine together with air through a purge valve, an air-fuel ratio learning value is renewed in accordance with a deviation between an air-fuel ratio feedback FAF value detected by an oxygen sensor and a FAFSM value obtained by smoothing the FAF value with a large smoothing constant. Further, renewal of the air-fuel ratio learning value is inhibited when the concentration of the evaporated fuel is high, and renewal of the air-fuel ratio learning value is executed even during purge execution by the purge valve when the concentration is low.
摘要:
An air-fuel ratio control apparatus for an internal combustion engine for learning and controlling an air-fuel ratio accurately even during execution of purging of evaporated fuel. The evaporated fuel generated in a fuel tank is adsorbed to a canister, and the adsorbed fuel is evaporated and purged together with air to the intake side of the internal combustion engine through a purge valve. During normal purge rate control by the purge valve, air-fuel ratio feedback values detected by an oxygen sensor are averaged, and the concentration of the evaporated fuel taken into the internal combustion engine through the purge valve is detected by the deviation from a stoichiometric air-fuel ratio 1 of the averaged value and the purge rate. Further, after the lapse of a predetermined period of time after purging is started, air-fuel ratio learning values are renewed in accordance with the air-fuel ratio feedback value and stored in a RAM.
