Embodiment Construction

[0017] According to an embodiment of the present invention, when a driver who does not intend to change the target following distance performs an acceleration operation or a deceleration operation, by suppressing the amount of change in the target following distance, it is possible to prevent the target following distance from being changed unintended by the driver.

[0018] Hereinafter, a following distance control device according to an embodiment will be described with reference to the drawings.

[0019] The following distance control device according to the embodiment is applied to an adaptive cruise control system (ACC system) installed in a vehicle. When there is a vehicle in front, the ACC system according to the embodiment performs following control of the vehicle in front to adjust the distance from the vehicle in front to the target following distance; when there is no vehicle in front, the ACC system performs constant speed control to adjust the speed of the host veh...

Abstract

A following distance control device (1) that controls a vehicle to regulate a distance to a preceding vehicle to a target following distance, the following distance control device (1) including: detecting unit (30) that detect at least one of acceleration operation (12) or deceleration operation (13) by a driver; a target following distance changing unit that changes the target following distance on the basis of the acceleration operation (12) or the deceleration operation (13) by the driver that is detected by the detecting unit (30); and an inhibition unit that inhibits a changing amount of the target following distance by the target following distance changing unit when the given acceleration operation (12) or the given deceleration operation (13) is executed.

Description

technical field [0001] The present invention relates to a following distance control device that controls a vehicle to adjust a distance from a preceding vehicle to a target following distance, and also relates to a following distance control method. Background technique [0002] The following distance control device performs various vehicle controls (throttle control, brake control, etc.) to adjust the distance to the vehicle in front to a target following distance so that the host vehicle travels at a speed relative to the vehicle in front. In the devices disclosed in Japanese Patent Application Publication No. 2004-216964 (JP-A-2004-216964) and No. 2004-216965 (JP-A-2004-216965), during the following distance control, when driving When the driver starts to operate the brake or the accelerator, the following distance control is canceled, and when the driver stops the above operation, the following distance control is resumed. Specifically, in these devices, when the follo...
