VEHICLE CONTROL APPARATUS

摘要

A vehicle control apparatus for implementing inter-vehicle distance control of a vehicle carrying the apparatus behind a preceding vehicle. In the apparatus, an offset storage is configured to calculate an offset that is a difference between detected distances to first and second targets, and store the offset associated with the first target forward of the second target. The inter-vehicle distance control may be implemented based on a distance calculated by subtracting the offset from the detected distance to the first target. An offset eraser is configured to, based on the presence or absence of relative displacement between the first and second targets, determine whether or not the first and second targets belong to different vehicles, and when the first and second targets belong to different vehicles, erase the offset stored by the offset storage.

1. A vehicle control apparatus for implementing inter-vehicle distance control of a vehicle carrying the apparatus behind a preceding vehicle based on reflected waves from at least one target that is a reflecting portion of the preceding vehicle, the vehicle carrying the apparatus being referred to as a subject vehicle, the reflected waves being radar waves transmitted to a front of the subject vehicle and then reflected from the at least one target, the apparatus comprising:
a target information acquirer configured to acquire target information about each of the at least one target from the reflected waves, the target information including a detected distance from the subject vehicle to the target of the preceding vehicle; an offset storage configured to, in the presence of first and second targets forward of the subject vehicle, the first target being forward of the second target, the second target being a target recognized as a rear end of the preceding vehicle, calculate and store an offset associated with the first target, the offset being a difference between the detected distance to the first target and the detected distance to the second target; a controller configured to implement the inter-vehicle distance control to follow the second target based on the detected distance to the second target, and when the second target fails to be detected, implement the inter-vehicle distance control based on a distance calculated by subtracting the offset associated with the first target stored by the offset storage from the detected distance to the first target; and an offset eraser configured to, based on the presence or absence of relative displacement between the first and second targets, determine whether or not the first and second targets belong to different vehicles, and when it is determined that the first and second targets belong to different vehicles, erase the offset associated with the first target stored by the offset storage.
