    摘要: An FM signal generator generates a frequency-swept FM signal, which is radiated as a beam from a transmission and reception antenna. The transmission and reception antenna is angularly moved by an antenna actuator to scan the beam. An echo signal reflected from a target and a signal related to the frequency-swept FM signal are mixed into a beat signal, whose frequency spectrum is analyzed by a frequency analyzer. A target detector determines the distance up to the target based on the frequency spectrum of the beat signal. A BPF processor comprises a bandpass filter which extracts a frequency component corresponding to the distance up to the target from the beat signal. A bearing calculator compares the level of a signal that has passed through the BPF processor with a threshold level to determine a bearing and a width of the target.

    摘要: A vehicle 2 performs fault diagnosis of the vehicle and calculation of the service life of parts using information obtained from sensors and control units, and when the necessity for repair work of the vehicle arises, makes a repair request to an information center 1. The information center 1 having received the repair request notifies terminals of outlets 4 of the repair request, to request the outlets 4 to transmit a service condition of their shop. The outlets 4 transmit the service conditions of the shop to the information center 1, in response to the repair request. The information center 1 relays the received service condition of each outlet 4 to the user, so that the user can select a desired service condition. The information center 1 then transmits contract completion information to the outlet 4 having proposed the service condition selected by the user, to mediate an agreement between the user and the outlet 4.

    摘要: A radar device for detecting distances and relative speeds of obstructions such as preceding vehicles has a stationary object identifier for identifying stationary objects such as roadside guard rails and the like and a stationary object eliminator for eliminating data identified as pertaining to such stationary objects. The stationary object identifier detects peak densities in a beat spectrum detected as a difference between transmitted and received frequencies of a radar beam modulated to rise and fall in frequency periodically and identifies peak groups having peak densities above a predetermined value as stationary objects. Therefore, it is possible to detect a stationary roadside object on the basis of peak densities. The stationary object eliminator eliminates data of peak groups identified as stationary objects by the stationary object identifier and thereby removes them as objects of combination processing for pairing rise side beat frequencies with fall side beat frequencies. As a result the amount of processing required for this pairing is reduced and the occurrence of wrong pairings is reduced and it is possible to eliminate the unnecessary calculation of distances and relative speeds of roadside objects.

    摘要: A multibeam FM radar system has an FM radar module for transmitting beams of FM signals whose frequencies linearly vary in rising and falling periods, in respective different directions with adjacent ones of the beams overlapping each other, receiving echo signals from a given beam, and mixing the FM signals and the echo signals into beat signals corresponding to said given beam. The multibeam FM radar system also has a main radar circuit including a central processing unit for identifying pairs of beat frequencies in the beat signals corresponding to said given beam, and processing the pairs of the frequencies to calculate distances up to and/or relative speeds with respect to objects within said given beam which have produced the echo signals, while comparing the frequencies within said identified pairs of beat frequencies to beat frequencies within a beam adjacent to said given beam to produce a detected result corresponding to an object producing echo signals within said given beam.

    摘要: A three-dimensional-object can be effectively detected. A pair of image capture devices capture a three-dimensional-object and calculate disparity component data of subdivided-image regions, respectively. On a basis of the disparity component data, gray scale values indicative of distances from the image capture device are calculated and a gray scale image in which each region has its corresponding gray scale value is generated. A model of the three-dimensional-object is defined and correlation values is calculated to show the degree of a similarity between the model and the image subdivided regions in the gray scale image. The model is a two-dimensional image with a shaping characteristic when the three-dimensional object is viewed from positions of the image capture devices while each subdivided region of the two-dimensional image has a gray scale value indicative of a distance from the image capture device at a portion corresponding to the three-dimensional object. The correlation values are calculated on a basis of gray scale values of the model and those of the image region in the gray scale image. The model and an image region with the highest correlation value are detected in the gray scale image, so that a three-dimensional image is detected.

    摘要: A network system includes a plurality of vehicle-mounted, microcomputer-based electronic devices each having & distributed operating system for performing data communication and distributed processes among the electronic devices. By virtue of the distributed operating system, information resources and hardware resources can be used in common by two or more of the vehicle-mounted electronic devices. Thus the network system has a higher level of network transparency. Because the electronic devices can operate independently and they are interconnected by a common interface called network, a revision to the program of one of the electronic devices or entry of a new electronic device to the network system does not induce tedious and time-consuming version-up of the program of any other electronic device.

    摘要: An object detecting system detects an object using an FM-CW wave, so that even if either one of rising-side and falling-side peak frequencies is missing, a plurality of objects can be accurately recognized by accurately combining pluralities of rising-side and falling-side peak frequencies. When it is determined that either one of rising-side and falling-side peak frequencies is missing, the combination of the peak frequencies is determined by calculating the missing peak frequency based on a peak frequency which is not missing.
