The invention provides a driving assistance system for a vehicle and a driving assistance external device, which can appropriately select a vehicle to be monitored as a collision avoidance object from other vehicles, thereby realizing driving assistance under a low calculation load. The control device (15) sets, as a reference vehicle (ST7), a vehicle in front of the other vehicles (2) that has passed the host vehicle (1), and sets, as a target vehicle (ST17) that should be monitored as a target for collision avoidance, a vehicle that differs from the reference vehicle and has a prescribed correlation with the travel trajectory of the reference vehicle (ST7). A driving assistance device (14) is controlled on the basis of the position information of the subject vehicle so as to avoid a collision between the host vehicle (1) and the subject vehicle (ST20). 本发明提供车辆的驾驶辅助系统以及驾驶辅助外部装置，能够从其他车辆中适当地筛选出应作为避免碰撞的对象被监视的车辆，从而实现低运算负荷下的驾驶辅助。控制装置(15)将其他车辆(2)中的通过了本车辆(1)的前方的车辆设定为基准车辆(ST7)，将相对于基准车辆的行驶轨迹具有规定的相关性的不同于基准车辆的车辆设定为对象车辆
