摘要： A vehicle-surroundings monitoring apparatus is free from mistakenly identifying a lane marker on a road surface or a guard rail as a vehicle traveling in the blind spot of a nearby lane. A distance detecting section detects the distance up to a vehicle which is traveling in the blind-spot of a nearby lane and which is captured by a plurality of windows as set on a display screen. A detecting range restricting section restricts a distance detecting range for each window to a predetermined range to thereby select as a nearby vehicle an object to which the distance is within the predetermined range.

摘要： A vehicle following apparatus is able to continuously or successively measure, once a target vehicle to be followed is determined, the distance to the target vehicle in a stable and reliable manner even if the subject vehicle, on which the apparatus is mounted, is momentarily caused to move in the vertical or horizontal direction with respect to the target vehicle. A pair of first and second image sensors including a pair of optical systems are disposed at a predetermined distance from each other for optically sensing a plurality of objects including a preceding vehicle running ahead of the subject vehicle. A first window containing therein an image of the preceding vehicle as sensed by the image sensors is defined on a screen of a display. A second window is also defined on the screen adjacent the first window for catching the background of the preceding vehicle. The position of the first window is controlled to automatically follow the image of the preceding vehicle by measuring the distances to the objects in the respective first and second windows.

摘要： In a throttle valve controlling apparatus, there is provided a pair of first and second throttle valves. The first throttle valve is rotated by an electrically controlled actuator means, whereas the second throttle valve is rotated by an accelerator pedal. A first return spring is provided on the first throttle valve so as to return this valve to a first closed position when the electrically controlled actuator means is brought into malfunction, by which an engine speed is rapidly reduced. Under this malfunction condition, the second throttle valve can be independently controlled by the accelerator pedal.

摘要： An electronic fuel supply device for an automotive engine has a vortex flow sensor for sensing the flow of suction air into the engine, an electromagnetic valve which driven for a predetermined time in synchronism with the frequency output from the vortex flow sensor so as to permit the passage of fuel therethrough, and a control valve for limiting the flow of fuel through the electro-magnetic valve. The fuel is metered by the electro-magnetic valve and the control valve, and the fuel may thus be supplied in metered amounts to the fuel injection valves in the respective cylinders for injection into the engine.
