Abstract
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 that is a reflecting portion of the preceding vehicle. In the apparatus, a distance estimator is configured to calculate an estimated distance as an inter-vehicle distance between a rear end of the preceding vehicle and the subject vehicle based on an inter-vehicle distance variation calculated based on a relative speed of the target. A target determiner is configured to determine whether or not the target is displaced forward of the rear end of the preceding vehicle. A controller is configured to, when the target of the preceding vehicle is displaced forward of the rear end of the preceding vehicle, implement the inter-vehicle distance control based on the estimated distance calculated by the distance estimator.
