To provide a collision avoidance support system and a collision avoidance support device capable of reliably avoiding a collision between vehicles while avoiding the execution of unnecessary collision avoidance support in a scene where the vehicles are traveling on respective roads toward an intersection.SOLUTION: A collision avoidance support device of a first vehicle in a collision avoidance support system transmits a first radio signal representing position information and speed information on the first vehicle. Upon receipt of the first radio signal, a collision avoidance support device of a second vehicle in the collision avoidance support system acquires the position information and speed information on the first vehicle on the basis of the first radio signal. When determining based on the position information and the speed information, and position information and speed information on the first vehicle acquired by an ambient information sensor of the second vehicle that there is a possibility that the first vehicle and the second vehicle may collide with each other, the collision avoidance support device of the second vehicle transmits a second radio signal representing collision information. Upon receipt of the second radio signal, the collision avoidance support device of the first vehicle executes collision avoidance processing in the first vehicle.SELECTED DRAWING: Figure 5
【課題】交差点に向かってそれぞれの道路を車両が走行している場面において、不要な衝突回避支援の実施を回避しつつ、車両同士の衝突をより確実に回避することができる衝突回避支援システム及び衝突回避支援装置を提供する。【解決手段】衝突回避支援システムの第1車両の衝突回避支援装置は、第1車両の位置情報及び速度情報を表す第1無線信号を発信する。衝突回避支援システムの第2車両の衝突回避支援装置は、第1無線信号を受信した場合、第1無線信号に基づいて第1車両の位置情報及び速度情報を取得し、それら位置情報及び速度情報と、第2車両の周辺情報センサ装置により取得した第1車両の位置情報及び速度情報と、に基づいて第1車両と第2車両とが衝突する可能性があると判定した場合、衝突情報を表す第2無線信号を発信する。第1車両の衝突回避支援装置は、第2無線信号を受信した場合、衝突回避処理を第1車両に対して実施する。【選択図】図5
