Adaptive cruise control system and method for automotive vehicle with inter-vehicle distance control function
First Claim
1. An adaptive cruise control system for an automotive vehicle, comprising:
- an inter-vehicle distance detecting section that detects a presence of a preceding vehicle which is traveling ahead of the vehicle and detects an inter-vehicle distance between the vehicle and the preceding vehicle;
a vehicular velocity detecting section that detects a velocity of at least one of the vehicle and the preceding vehicle;
a target inter-vehicle distance setting section that sets a target inter-vehicle distance on the basis of said velocity of at least one of the vehicle and the preceding vehicle;
a vehicular traveling speed controlling section that controls a traveling state of the vehicle on the basis of the detected inter-vehicle distance and the target inter-vehicle distance; and
a delay providing section that provides a delay independent from any inherent delay in said vehicle velocity detection section for said velocity of at least one of the vehicle and the preceding vehicle, the delay provided detected velocity being used to set the target inter-vehicle distance, the target inter-vehicle distance setting section setting the target inter-vehicle distance on the basis of the detected velocity for which the delay is provided by the delay providing section.

Abstract
In adaptive cruise control method for an automotive vehicle, an inter-vehicle distance between the vehicle and a preceding vehicle which is traveling ahead of the vehicle is detected, a velocity of at least one of the vehicle and the preceding vehicle is detected, a traveling state of the vehicle is controlled on the basis of the detected inter-vehicle distance and a target inter-vehicle distance, a delay is provided for one of the detected velocities of the vehicle and the preceding vehicle which is used to set the target inter-vehicle distance at a time of a detection of one of the velocities of the vehicle and the preceding vehicle which is used to set the target inter-vehicle distance, and the target inter-vehicle distance is set on the basis of the detected velocity of one of the vehicle and the preceding vehicle for which the delay is provided.
