  • Patent number: 10453343
    Abstract: An object detection apparatus includes a first detection unit that detects an object based on a reflected version of probing waves transmitted by a first distance sensor and received as direct waves by the first distance sensor, a second detection unit that detects the object based on a reflected version of the probing waves received as indirect waves by a second distance sensor, a position calculation unit that calculates position data of the object using a trilateration method, a counter update unit that updates a counter value of a reliability level determination counter by an update amount, and an update amount setting unit that variably sets the value of the update amount depending on which position within detection areas of the first and second distance sensors the position data calculated in the current detection cycle shows the object to be in.

  • Patent number: 10451734
    Abstract: An object detecting apparatus includes a distance calculator that calculates a distance to the object, a wave height acquirer that acquires a respective peak value of the plurality of reflected waves, and multiple reflection determiner. When a reflected wave for which a first distance to the object is calculated to be the smallest in the reflected waves is defined as a first wave, and another reflected wave to which a second distance is calculated as twice or more integer times the first distance calculated for the first wave and a difference of the peak value relative to the first wave which is larger than a predetermined value is present in the reflected waves, the multiple reflection determiner determines that multiple reflection is occurring in a second wave or thereafter.

  • Patent number: 10436900
    Abstract: An object detection apparatus is applied to a movable body including an object detection sensor which transmits a search wave and receives a reflected wave of the search wave as detection information of an object, and detects the object present around the movable body based on the detection information. The apparatus includes a frequency detection section which detects an occurrence frequency of a disturbance signal at the same time within a predetermined transmission time period determined with reference to a transmission period of the search wave, and a disturbance determination section which determines presence or absence of occurrence of disturbance based on the occurrence frequency detected by the frequency detection section.
