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： An element is provided which operates in two selectable mode. The element converts the analog output of a knock sensor to a digital value in one mode and compares the analog output with the reference value in the other mode. The average output of the knock sensor is calculated from the digital value and the reference is calculated from the average output. In the occurrence of any knocking, the output of the knock sensor is greater than the reference.

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： A throttle control apparatus for engines comprises two throttle actuators for driving two corresponding main and sub throttle valves mounted in series in an intake pipe of an engine. An observer, to which the modern control theory is applied, presumes an opening degree of the main throttle valve in a normal condition, which occurs a predetermined time later, from an accelerator depression amount, which represents a throttle opening command, and an opening degree (angular position) of the main throttle valve. A failure detector quickly finds, from a deviation between the presumed opening degree of the throttle valve at the predetermined later time and an actual opening degree of the main throttle valve, that the main throttle valve has failed. When a failure occurs, the control of the sub throttle valve is started, making it possible to effect the throttle opening control with improved reliability.

摘要： A vehicle running guidance system using magnetic markers for the purpose of reducing the number of magnetic markers to be laid on a road surface. The magnetic nails are laid as magnetic markers on a road. The radio wave generator tags are also laid. The radio wave generator tags transmit road curve data for a distance of about 100 m in the running direction. Power for the radio wave generator tags is supplied from a magnetic generator on a vehicle. On the vehicle, the relative displacement from a magnetic nail is detected by a magnetic sensor, and at the same time the road curve data from radio wave generator tags is received by a radio wave receiving device. The controller determines the amount of steering, based on relative displacement with respect to magnetic nails and road curve data, and supplies it to the actuator. Transmission of road curve data contributes to reducing the number of magnetic nails.

摘要： A prism has at least two optical planes and one of the planes is a boundary plane with mixed fuel. On one of two planes, a light emitting element is mounted and illuminates light to the boundary plane through the prism. A light receiving element receives light reflected from the boundary plane and converts the reflected light into electrical signals. Then a detector modifies the electrical signals from the light emitting element according to the detecting result and outputs them as detecting signals representative of the fuel mixture ratio. The temperature of the mixed fuel may be detected by a temperature sensor in which case the electrical signals are also modified to compensate for temperature changes of the mixed fuel.
