Abstract: In an apparatus for monitoring an adjacent lane to a lane in which an own vehicle that is a vehicle carrying the apparatus is traveling, a travel trajectory calculation unit calculates a travel trajectory of the own vehicle based on odometry information of the own vehicle. An adjacent lane estimation unit estimates an adjacent-lane region based on the travel trajectory of the own vehicle. An other-vehicle determination unit determines whether or not a target (the other vehicle) is present in the adjacent lane based on a position of the target detected by an other-vehicle detector and the estimated adjacent-lane region.

Abstract: A radar apparatus includes a targeting unit that irradiates a radar wave and recognizes a detection subject using a reflected wave thereof. The targeting unit extracts, as a target, a peak that is confirmed to have historical connection over measurement cycles equal to or more than a predetermined targeting threshold, from peaks extracted from a power spectrum generated by frequency analysis. A rainy-weather determining unit determines that weather is rainy when a number of erroneous detections is greater than a predetermined rainy-weather determination threshold. The number of erroneous detections is a number of peaks that have been detected in a previous measurement cycle or earlier by the targeting unit and are not confirmed to have historical connection to a peak detected in a current measurement cycle. A parameter updating unit updates the targeting threshold so as to be a larger value as the number of erroneous detections increases when the rainy-weather determining unit determines that the weather is rainy.
