Preceding vehicle following cruise control system and the preceding vehicle following method

摘要

PROBLEM TO BE SOLVED: To provide a preceding vehicle follow-up running control apparatus that can flexibly change a target inter-vehicle distance temporarily so that the own vehicle may not enter the blind spot of a driver of a side vehicle without persisting to the target inter-vehicle distance set by an inter-vehicle setting method selected by the driver in a state where there exists a side vehicle running in parallel in other than a congestion state under the follow-up running to a preceding vehicle, and to provide a preceding vehicle follow-up running control method.;SOLUTION: A target inter-vehicle distance setting part 14 determines a safety level of a periphery vehicle state based on presence or absence of left side running vehicles and presence or absence of right side running vehicles, excluding the case when the own vehicle is in the congestion state, and when this determination determines that the safety level is low, changes the inter-vehicle distance to the parallel running time target inter-vehicle distance DL that is longer than the target inter-vehicle distance Dn set by an inter-vehicle setting method (i=n) selected by an inter-vehicle selection part 13.;COPYRIGHT: (C)2013,JPO&INPIT
