Object detecting device, and travel safety system for vehicle

Abstract

Stationary objects are determined from objects detected by a radar device mounted on a vehicle. Objects detected with a dispersion in the level of the reception of a reflected wave at a relative distance in a range of 20 m to 100 m that is equal to or smaller than a first threshold value, are extracted from the extracted objects, and objects existing on a predicted course for the vehicle is extracted from the extracted objects. Further, it is determined if one of the extracted objects detected with rate of decrease in level of reception at a relative distance in a range of 10 m to 20 m is equal to or larger than a second threshold value and with a level of reception equal to or smaller than a third threshold value is an object which provides no hindrance even if the vehicle passes over the object. A warning or an automatic braking is discontinued or moderated based on the type of object. Thus, it is possible to precisely determine whether the object detected by the radar device mounted on the vehicle is an object particularly providing no hindrance even if the vehicle travels astride the object as it is, or whether it is an object the contact of the vehicle with which is required to be avoided, thereby carrying out a precise warning or automatic braking.
