The invention provides a preceding vehicle determination system and a preceding vehicle determination method capable of improving preceding vehicle determination accuracy in consideration of an estimated error of a driving lane of a vehicle. A preceding vehicle determination system and a preceding vehicle determination method estimate, on the basis of the traveling situation of a host vehicle, a high-coverage region, which is a region in which the host vehicle is likely to travel, and estimate a medium-coverage region, which is a region in which the host vehicle is less likely to travel than the high-coverage region. On the basis of the position history of the preceding vehicle, the high-coverage region, and the medium-coverage region, it is determined whether or not the preceding vehicle is traveling ahead of the travel lane of the host vehicle.
本发明提供一种能够考虑本车辆的行驶车道的推测误差来提高前车的判定精度的前车判定系统及前车判定方法。前车判定系统及前车判定方法基于本车辆的行驶状况,推测本车辆可能行驶的区域即高盖然性区域,并且推测与高盖然性区域相比本车辆行驶的可能性较低的区域即中盖然性区域,基于前方车辆的位置履历、高盖然性区域和中盖然性区域,对前方车辆是否是正行驶在本车辆的行驶车道前方的前车进行判定。
