Abstract
A device for detecting obstacles, for use in vehicles, capable of correctly detecting obstacles without driving up the cost. the device includes a signal processing device 3 for detecting an obstacle Z based on reception signals A, B from a plurality of sensor devices 1, 2, wherein the signal processing device includes detection region-setting devices 31, 32 for dividing the region around the vehicle into a plurality of detection regions, probability-of-presence operation devices 33, 34 for operating the in-the-region presence probabilities P, Q of obstacle, a probability distribution operation device 35 for operating the in-the-region presence probabilities for each of the detection regions, and an obstacle detection device 36 for judging the regions S where the obstacles exist based on the in-the-region presence probabilities R in the distribution of presence probabilities, wherein the obstacle detection device judges detection regions exhibiting the in-the-region presence probabilities that are larger than a predetermined threshold value to be the regions where the obstacles exist among the in-the-region presence probabilities in the detection regions in the distribution of presence probabilities.
