Patent ID: 10504370

Abstract:
In a collision avoidance apparatus (1), a first information acquisition unit (7) generates first information that includes the position, speed and advancement direction of a first mobile body, and obtains first information from a first information transmitting unit (1) having a transmitting function. A second information acquisition unit (9) obtains second information that includes the position, speed and advancement direction of a second mobile body. A first mobile body prediction unit (11) predicts positions (P1) of the first mobile body at future time points T, based on the first information, and a second mobile body prediction unit (13) predicts the positions (P2) of the second mobile body at the time points T, based on the second information. A judgement unit (15) judges whether or not the positions (P1) of the first mobile body and the positions (P2) of the second mobile body satisfy predetermined conditions, and if the conditions are satisfied, a signal outputting unit (17) outputs a signal which is specific to that case.
