Patent number: 9266534Abstract: A vehicle control apparatus for implementing inter-vehicle distance control of a subject vehicle carrying the apparatus behind a preceding vehicle based on reflected waves from a target of the preceding vehicle. A target-pair distance is a distance between the target and a non-target reflection point that is closer to the subject vehicle than the target. A corrected distance calculator is configured to, in the presence of the target-pair distance being recognized, calculate a first corrected distance by subtracting the target-pair distance from a detected distance between the target and the subject vehicle, and in the absence of the target-pair distance being recognized, calculate a second corrected distance by subtracting an offset that is the previously set target-pair distance from the detected distance. A controller is configured to implement the inter-vehicle distance control based on the first or second corrected distance depending on the presence or absence of the target-pair distance being recognized.Type: GrantFiled: July 10, 2015Date of Patent: February 23, 2016Assignees: DENSO Corporation, Toyota Jidosha Kabushiki KaishaInventors: Mitsuhiro Tokimasa, Youhei Masui, Minoru Nakadori
