摘要： There are provided apparatuses for generating the motion path of an object. One apparatus includes an input unit for inputting information representative of the position of a start point of the motion of an object, at least one of the magnitude and direction of a velocity at the start point, an end point of the motion of the object, and at least one of the magnitude and direction of a velocity at the end point, and a calculation unit for calculating a motion path from the start point to the end point, in accordance with the information inputted to the input unit. As an alternative of the position and velocity of an object, the rotary angle and angular velocity of an object may be used to represent the facing direction of the object. Another apparatus includes a display device for displaying information of the position of an object and an icon representative of the time corresponding to the position of the object, and a calculator for calculating information representative of the motion path, in accordance with the information entered by the icon and information representative of at least one of the magnitude and direction of a velocity at the position of the object. The motion path is then displayed on the screen. The motion of an object can be easily defined and smoothly coupled to a succeeding or preceding motion on each key frame. The path and/or surface reflection attribute of an object can be defined with a small number of procedures.

摘要： A three-dimensional graphic system includes a scene origination equipment, a rendering apparatus and a display device. The user interface unit of the scene origination equipment displays on the display screen of the display device. The user interface unit of the scene origination equipment displays on the display screen of the display device a graph which represents the relationship between a distance from a point generated with a cursor and the density of the generated point. The setting of the shape of the displayed graph is accepted on the display screen, and the relationship between the distance from the generated point of the cursor and the density of the generated point is determined in accordance with the accepted setting of the shape of the graph. The image generation unit of the scene origination equipment displays the cursor on the display screen, and generates an image in which the point generated with the cursor and points vicinal to the generated point are drawn at densities conforming to the determined relationship. The rendering apparatus generates a video graphic in which the generated image is mapped on an object and displays the video graphic on the display screen.

摘要： Even in such an arrangement in which the throttle valve is operated independently of the engine control system, abnormal engine behavior is ensured to be detected such that a necessary fail-safe operation should be taken. The arrangement of the invention is comprised of the electronically controlled throttle system, engine control system and engine speed monitoring unit, wherein the electronically controlled throttle system is allowed to monitor engine behaviors. Thereby, in the case when the throttle valve is operated independently of the engine control system, if its engine behavior becomes abnormal relative to its drive contents, the engine system senses the abnormality, and takes a fail-safe operation such as to stop operation of the throttle valve and the like.

摘要： An electronic control throttle body has a default mechanism for securing the self-propelling of a vehicle at the time of faulty. A throttle control unit controls the position of a throttle valve by using a motor on the basis of a target throttle valve opening degree obtained by an engine control unit. In this respect, when the target throttle valve opening degree inputted from the engine control unit crosses over a default opening degree f0 of a default mechanism, an integration value having been added is set to 0, and an integration value having been calculated hereinafter is added to the set value to thereby perform a feedback control.

摘要： A throttle valve control system and a control method thereof prevents an output of throttle sensors from becoming discontinuous at a point of switching the throttle sensors, and obtains a continuous output over the whole range of the sensor output, and accordingly can perform highly accurate throttle control. The system includes a first A/D converter for converting an output signal of a throttle sensor into a digital signal, an amplifier for amplifying the output signal of the throttle sensor, a second A/D converter for converting the amplified output signal into a digital signal and an amplification factor adjuster for receiving outputs from one or the other of the A/D converters and scaling the received output signal. A correction is provided for the amplification factor of the adjuster whereby a continuous actual opening degree signal without any step is obtainable over the entire range of the throttle sensor output.
