Abstract
In a distance detection apparatus for a vehicle, a distance detection unit is configured to detect object distances to an object around the vehicle by transmitting and receiving radar waves. A detection distance estimation unit is configured to estimate an estimated detection distance having a maximum value of the object distance, based on the object distances and intensities of the radar waves reflected by the object. A lost-track distance estimation unit is configured to estimate, as a lost-track distance, the object distance at a timing of transition from a detected state where the object is recognized to a non-detected state where the object is not recognized, based on a result of detection by the distance detection unit. A performance determination unit is configured to determine a degradation of detection performance of the distance detection unit based on the estimated detection distance and the lost-track distance.
