摘要： A gas component detection apparatus for detecting gas components contained in an exhaust gas from a combustion device and determining an air-fuel ratio of an air-fuel mixture supplied thereto. A gas component detecting element composed of a semiconductive metal oxide is contacted by the exhaust gas andexhibits variable electric resistances according to the concentrations of the gas components. The electric resistance is taken out as an electric signal through two electrodes disposed either on the surface of the detecting element exposed to the exhaust gas or within the detecting element adjacent that exposed surface. A porous coating layer having an exhaust gas permeability covers the surface of the detecting element exposed to the exhaust gas so as to prevent poisonous substances contained in the exhaust gas from depositing on that exposed surface of the detecting element. The coating layer is formed of a metal oxide having electrically insulating properties and carries therein a catalyst promoting an oxidation reaction of the exhaust gas. The detecting element exhibits an abruptly changed electric resistance when the actual air-fuel ratio of the air-fuel mixture supplied into the combustion device is deviated from a stoichiometrical air-fuel ratio, thereby enabling the control of the air-fuel ratio of the air-fuel mixture.

The guideway transit system includes a noncontact vehicle guiding system and a contact vehicle guiding system. The noncontact vehicle guiding system detects information relating to a lateral position of a vehicle on a road and steers the vehicle to move along a predetermined path on the road based on the detected information. The contact vehicle guiding system which restricts a lateral position of the vehicle by a contact between a guide wheel which laterally projects from the vehicle and a guide wall provided on a side of the road. The guideway transit system further includes a controller which prohibits steering of the vehicle by the noncontact vehicle guiding system when a lateral position of the vehicle is restricted by the contact vehicle guiding system. An automated vehicle which is used in the guideway transit system is also provided.

摘要： A traveling guidance system provides a traveling vehicle with various types of data indicating the flow of traffic to smooth travel. The speed and pass time data of the preceding vehicle is sent to an electronic wave tag laid on a road surface. The electronic wave tag then sends the data to the succeeding vehicle when it passes over the electronic wave tag. Furthermore, the received data is sent to a control center through communication equipment, which predicts the occurrence of traffic congestion based on the speed and pass time data of vehicles at each point and sends the prediction to electronic wave tags at points where the occurrence of traffic congestion is predicted. Traffic data from the control center is sent to passing vehicles through the electronic wave tag and each passing vehicle controls its travel based on the traffic data.

摘要： The invention is directed to a throttle control apparatus for controlling an opening of a throttle valve in an internal combustion engine, in response to operation of an accelerator operating mechanism. The apparatus includes a motor, a clutch, and a control circuit which controls the clutch to selectively take one of a first position of the motor engaged with the throttle valve and a second position disengaged therefrom. There is provided a first detector for producing a first signal corresponding to an amount of operation of the accelerator operating mechanism. Also provided is a second detector for producing a second signal corresponding to an opening angle of the throttle valve. Independent of the control unit, it is determined in accordance with the first and second signals if there is an abnormality, in which the throttle valve opens at an angle more than a predetermined angle when the accelerator operating mechanism is positioned at its initial position. When the abnormality continues for more than a predetermined time period, a signal indicative of the abnormality will be produced, and the clutch will be caused to disengage the motor from the throttle valve. When the signal indicative of the abnormality is continuously produced after the clutch disengages the motor from the throttle valve, the supply of fuel to the engine will be cut off.

摘要： A method for detecting knocking in internal combustion engine, wherein a plurality of constants K is stored corresponding to a plurality of ranges of engine speed. A reference value is calculated from a means value of an output signal of a knock sensor, from the constant K corresponding to an engine speed and from a predetermined offset value, through a calculation of multiplying the mean value by the constant K and adding the offset value to the result of the multiplication. Then an output signal, newly provided from the knock sensor after the calculation of the mean value, is compared with the reference value so as to decide that knocking occurs in the engine when the newly given output signal of the knock sensor exceeds the reference value. Therefore, the reference value can be suitably determined corresponding to the engine speed so that a detectable lower limit of knocking intensity is kept to be substantially constant.

摘要： Engine parameter signals indicative of the operating condition of the engine and an air-fuel ratio signal indicative of whether the air-fuel ratio condition of the engine is on the rich side or the lean side relative to a stoichiometric condition are produced. When the engine operates under a predetermined state, the fuel feeding rate to the engine is controlled in response to the engine parameter signals and the air-fuel ratio signal, by a closed loop control operation, in order to determine a learning control correction factor F.sub.G. In the closed loop control operation, a feedback correction factor F.sub.B is calculated depending upon the air-fuel ratio signal, and the fuel feeding rate is corrected depending upon the calculated factor F.sub.B, so as to control the air-fuel ratio condition to a condition close to the stoichiometric condition. At the same time, the learning control correction factor F.sub.G is adjusted, so as to settle the feedback correction factor F.sub.B within a predetermined range while at the same time maintaining the air-fuel ratio condition close to the stoichiometric condition. After the closed loop control operation is completed, the fuel feeding rate is controlled, by open loop in response to the engine parameter signals and the adjusted learning control correction factor F.sub.G, so as to control the air-fuel ratio condition at a desired condition which is different from the stoichiometric condition.

摘要： A fuel supply system for use in an internal combustion engine equipped with a three way catalytic converter which reduces the amount of NO.sub.x and oxidizes CO and HC at the same time, for controlling air fuel ratio by using an electronic circuit. According to this fuel supply system, when the internal combustion engine is in the low load running mode, the air fuel ratio of the mixture charge to be supplied to the engine is increased. In addition, when cooling water in the internal combustion engine remains above a given temperature and the load of the engine is over a given level, then the mixture charge is maintained at an increased air fuel ratio (a lean mixture charge) rather than at the stoichiometric air fuel ratio. In addition, there is provided means for slowing down a transient phase from the stoichiometric air fuel ratio to the increased air fuel ratio or vice versa.
