Abstract: A radar system includes an arithmetic processing unit, which calculates the second derivative of the intensity of a reflected wave and determines whether a target is an upper structure or a vehicle, based on the second derivative. Alternatively, the arithmetic processing unit decomposes the waveform of the intensity of the reflected wave into frequency components and determines whether the target is an upper structure or a vehicle, based on the intensity of a predetermined frequency component.

Abstract: A radar system includes an arithmetic processing unit, which sends a warning command to a warning device when a local minimum point of the intensity of the reflected wave from a target within a predetermined detection range is detected. By determining whether it is necessary to send a warning command based on whether there is a local minimum point of the intensity within the detection range, it is made possible to determine whether it is necessary to send a warning command more quickly as compared to the conventional system.

Abstract: An imaging mechanism captures an image of a face of a driver of a vehicle. A first image processor performs image processing on a wide portion of the face of the driver in a first image using a first image captured by the imaging mechanism. A second image processor performs image processing on a part of the face of the driver in a second image captured by the imaging mechanism at a higher exposure than the exposure of the first image, using the second image.

Abstract: In an electronic apparatus, a first microcomputer is monitored by a second microcomputer, which periodically transmits data relating to a main function to the first microcomputer to be processed. The first microcomputer periodically updates a variable value, performs a predetermined calculation operation whose final result should be a specific fixed value, adds that final result to the updated variable value to obtain a sum value, and transmits the sum value and updated variable value concurrently to the second microcomputer. The second microcomputer determines that the first microcomputer is operating abnormally if the difference between the received sum value and variable value is not equal to the specific fixed value.

Abstract: A radar sensor receives a radar wave signal through a radome in each of antennas while judging existence of an attenuating thing in a detecting unit. This unit extracts a maximum level channel from receiving channels assigned to the antennas every modulation period, calculates a difference in signal level between the maximum level channel and each receiving channel every modulation period, sets each receiving channel corresponding to large level differences in one measuring period including plural modulation periods as a candidate channel every measuring period, increments a preliminary variable of each candidate channel every measuring period, increases a final variable each time the preliminary variable of at least one receiving channel reaches or exceeds a preliminary value in one measuring period, and judges in response to the final variable reaching a final value that the attenuating thing attenuates the radar wave directed toward the random.

Abstract: An on-vehicle apparatus for recognizing objects is provided. The apparatus comprises a transmission/reception unit, detection unit, estimation unit, and specification unit. The transmission/reception unit transmits a medium wave toward a desired directional range from the vehicle and receives reflected waves of the medium wave and the detection unit detects objects existing in the desired directional range on the basis of the reflected wave. The estimation unit estimates a possibility that each detected object has been detected based on a reflected wave from a first part (e.g., cabin) of a further vehicle other than a second part (e.g., rear part) of the further vehicle, the first part being other than the second part that is the closest in distance to the apparatus-mounted vehicle. The specification unit specifies the second part as an object to finally be recognized of the apparatus-mounted vehicle depending on an estimated result by the estimation unit.
