  • Patent number: 9688272
    Abstract: A surroundings monitoring apparatus includes a detection unit configured to detect information on the surroundings of a host vehicle and a tracking unit configured to track a position and a speed of an obstacle in the surroundings of the host vehicle based on the result of detection by the detection unit. The tracking unit is configured to determine whether or not a tracked first obstacle is entering a blind spot area of the detection unit. In a case where it is determined that the first obstacle is entering the blind spot area of the detection unit and when a tracked second obstacle has passed the blind spot area where the first obstacle entered, the tracking unit determines that the first obstacle is not present in the blind spot area.
