Abstract:
1. A pre-crash safety system causing, when a possibility of a collision between a first mobile object equipped with a radar device and a second mobile object that approaches the first mobile object exists after a prediction of a collision therebetween is made, the first mobile object to conduct a safety measure operation, the pre-crash safety system comprising: a collision prediction unit that makes the prediction of a collision between the first mobile object and the second mobile object that has entered a monitoring area of the radar device; and a control unit that causes the first mobile object to conduct the safety measure operation based on a result of the prediction of a collision made by the collision prediction unit, wherein the control unit does not cause the first mobile object to conduct the safety measure operation if, after the second mobile object has entered the monitoring area, a reflection point coordinate which represents a reflection point of a radar wave on the second mobile object is positioned within a predefined direction range which is a range from a predetermined first direction to a predetermined second direction when viewed from the first mobile object, and the predefined direction range is a range in which the second mobile object is possibly falsely recognized, by the radar device, to be approaching toward the first mobile object due to a movement of a reflection point of a radar wave on a surface of the second mobile object even though the second mobile object is, in fact, not approaching toward the first mobile object.
