US 2020/0047756 A1 · OPTIMUM HEADWAY DISTANCE SETTING SYSTEM AND OPTIMUM HEADWAY DISTANCE SETTING METHOD USING THE SAME

Abstract

The optimum headway distance setting method may include determining whether or not to stop the speed adjustment operation for a vehicle by a driver of the vehicle by a control unit in the state detecting a front vehicle 1F which is traveling in front of the vehicle; determining whether or not to be stabilization of a headway distance between the vehicle and the front vehicle by the control unit when the speed adjustment operation for the vehicle is stopped; setting the optimum headway distance configured to set the stabilized headway distance as an optimum headway distance according to a traveling propensity of the driver by the control unit, and stores the optimum headway distance in the control unit.

Dependent claims

An optimum headway distance setting system for maintaining a distance between a vehicle and a front vehicle which is traveling in front of the vehicle, the optimum headway distance setting system comprising:

a controller of controlling a traveling of the vehicle and configured to detect the front vehicle, and in a response that a relative speed between the vehicle and the front vehicle is within a predetermined speed without a speed adjustment operation from a driver, to set a headway distance between the vehicle and the front vehicle as an optimum headway distance according to a traveling propensity of the driver.

An optimum headway distance setting method, including:

determining, by a controller, when to stop a speed adjustment operation for a vehicle by a driver of the vehicle while a front vehicle which is traveling in front of the vehicle is detected by the controller;
determining, by the controller, when to be stabilization of a headway distance between the vehicle and the front vehicle in a response that the speed adjustment operation for the vehicle is stopped by the controller;
and
setting by the controller, an optimum headway distance configured to set the stabilized headway distance as the optimum headway distance, according to a traveling propensity of the driver by the controller, and to store the optimum headway distance in the controller.
