Abstract: A monitoring-target-region setting device includes: an object detector that detects one or more objects present around an own vehicle; a discriminator that discriminates, on the basis of position information of the own vehicle accumulated in every determined cycle, whether the own vehicle is located within a determined distance range from an assumed region; a monitoring-target-region setter that sets, when the own vehicle is located within the determined distance range, a monitoring target region including the assumed region and being updated according to the position information of the own vehicle; and an object selector that selects, from the one or more objects detected in the monitoring target region, a target for which alarm is performed.

Abstract: An on-board radar apparatus includes a transmitter/receiver that transmits a radar signal to a detection range every frame and receives one or more reflected signals which are the radar signal reflected by one or more objects; a detector that detects, every frame in each direction within the detection range, a position of a reflection point closest to the on-board radar apparatus as a boundary candidate position, which serves as a boundary with a region where no object exists within the detection range, among one or more reflection points detected on the basis of the one or more reflected signals; a calculator that calculates movement amount concerning an amount of movement of the on-board radar apparatus; an estimator that generates, every frame in each direction within the detection range, an estimated boundary position by converting the boundary candidate position detected in a past frame into a boundary position in a current frame on the basis of the movement amount; and a smoother that performs, every frame in each direction within the detection range, smoothing processing by using the boundary candidate position in the current frame and the estimated boundary position to calculate a boundary position with the region where no object exists within the detection range and outputs the calculated the boundary position to a driving support apparatus.
