Abstract: The technique allows avoiding collision with an object that is difficult to detect with a radar sensor. A collision avoidance apparatus is an apparatus for an autonomous vehicle including at least one radar sensor for transmitting a radar wave and receiving a reflected wave from an object. The apparatus includes a processor that obtains, from a signal received by the at least one radar sensor, information about a position of the object and information about a reflected power level of the reflected wave, a generator that generates, in response to the reflected power level being higher than or equal to a predetermined value, information about a travel-restricted area being an area adjacent to the object and in which the autonomous vehicle is restricted from traveling, and an output unit that outputs the information about the travel-restricted area.

Abstract: In a radar apparatus of the present invention, a ghost deciding unit decides whether or not a first condition that a first object candidate and a second object candidate are in the same direction with respect to the transmission/reception unit is satisfied, and then decides whether or not a second condition that, of the first and second object candidates, a reflection power from the first object candidate located farther away from the transmission/reception unit is smaller than a reflection power from the second object candidate located closer to the transmission/reception unit is satisfied. The ghost deciding unit decides that only when the first condition and the second condition are satisfied, the first object candidate is a ghost.

Abstract: A control device for a robot that works in cooperation with a worker includes a radar transmission-reception section that transmits a radar wave to a co-working area in which the worker and the robot work together in cooperation and receives a reflected wave resulting from the radar wave being reflected off an object in the co-working area, a radar data processor that calculates, based on the reflected wave received by the radar transmission-reception section, a reflected power level of the object in the co-working area, and a controller that performs interference reduction to reduce interference between the robot and the worker in response to a presence of an object having a reflected power level calculated by the radar data processor higher than or equal to a predetermined threshold in the co-working area. The technique reduces accidental interference between a robot and a worker working in cooperation with each other.
