    摘要： An approaching vehicle detecting system that detects an approaching vehicle on the basis of sounds collected by a plurality of sound collectors mounted on a host vehicle determines whether a transverse moving direction of a sound source detected by the plurality of sound collectors is a direction approaching the host vehicle, determines whether a vertical position of the sound source detected using the plurality of sound collectors is in the same plane as that of the host vehicle, and detects that sound source as the approaching vehicle when it is determined that the transverse moving direction of the sound source is the direction approaching the host vehicle and the vertical position of the sound source is in the same plane as that of the host vehicle.

    摘要： A sound source detection system for detecting a sound source (e.g., running sound of a vehicle) based on sound collected by microphones extracts characteristic amounts from the sound collected by the microphones, sets a plurality of classes according to the position of the sound source by a multi-class pattern recognition method (e.g., multi-class SVM) using the characteristic amounts, extracts characteristic amounts from sound collected by the microphones for detection of a sound source, determines a class to which the extracted characteristic amounts belong, from the preset plurality of classes, and estimates the sound source based on the class.

    摘要： To provide a method for controlling a NOx reduction system which can remove NOx with a satisfactorily high efficiency even under low-temperature operating conditions as in diesel cars. The NOx reduction system comprises NOx treatment means disposed in an exhaust passage in an internal combustion engine, and air-fuel ratio control means for bringing the air-fuel ratio of an exhaust gas to a lean or rich state. The NOx treatment means comprises at least a first catalyst layer containing a solid acid catalyst capable of adsorbing ammonia and a second catalyst layer containing a noble metal and a cerium oxide material. The second catalyst layer and the first catalyst layer are stacked in that order on a carrier, and the first catalyst layer constitutes the uppermost layer. The air-fuel ratio control means controls so that the lean state and the rich state are repeated at predetermined intervals. According to the above constitution, NOx is passed through the first catalyst layer in the lean state and is temporarily stored in the second catalyst layer. Thereafter, in the rich state, NOx is converted to NH3 and is restored in the first catalyst layer. When the state is again returned to the lean state, NH3 is converted to nitrogen which is finally released from the first catalyst layer.
