US 2026/0301575 A1 · METHOD AND DEVICE FOR PREVENTING FORWARD COLLISION OF VEHICLE

Abstract

A method for preventing a forward collision of a vehicle includes receiving preceding traffic information including a location of the vehicle, a travel route, and at least one preceding vehicle speed information, determining road congestion based on the preceding traffic information, outputting a congestion notification in response to the road congestion, determining whether to deactivate smart cruise control in response to the congestion notification, reducing a speed of the smart cruise control when the smart cruise control is not deactivated, increasing an inter-vehicle distance to a preceding vehicle based on the reduced smart cruise control speed, determining whether a distance to the preceding vehicle is equal to or smaller than a predetermined distance, and restoring a predetermined speed and an inter-vehicle distance when the distance to the preceding vehicle is equal to or smaller than the predetermined distance.

Dependent claims

A method for preventing a forward collision of a vehicle, the method comprising:

receiving preceding traffic information including a location of the vehicle, a travel route, and at least one preceding vehicle speed information;
determining, by a controller, road congestion based on the preceding traffic information;
outputting, by the controller, a congestion notification in response to the road congestion;
determining, by the controller, whether to deactivate smart cruise control in response to the congestion notification;
reducing, by the controller, a speed of the smart cruise control based on that the smart cruise control is not deactivated;
increasing, by the controller, an inter-vehicle distance to a preceding vehicle based on the reduced smart cruise control speed;
determining, by the controller, whether a distance to the preceding vehicle is equal to or smaller than a predetermined distance;
and
restoring, by the controller, a predetermined speed and an inter-vehicle distance based on that the distance to the preceding vehicle is equal to or smaller than the predetermined distance.

6 more elements

A device for preventing a forward collision of a vehicle, the device comprising:

an Audio Video Navigation (AVN) receiving navigation information including a location of the vehicle and a travel route;
a communicator receiving preceding traffic information including at least one preceding vehicle speed information;
a cluster outputting at least one notification;
a driver controlling at least one of a speed and a braking of the vehicle;
and
a controller operatively connected to the AVN, the communicator, the cluster, and the driver and controlling at least one of the AVN, the communicator, the cluster, and the driver,
wherein the controller controls the driver to:
determine road congestion based on the preceding traffic information;
output a congestion notification via the cluster in response to the road congestion;
determine whether to deactivate smart cruise control in response to the congestion notification;
reduce a speed of the smart cruise control based on that the smart cruise control is not deactivated;
increase an inter-vehicle distance to a preceding vehicle based on the reduced smart cruise control speed;
determine whether a distance to the preceding vehicle is equal to or smaller than a predetermined distance;
and
restore a predetermined speed and an inter-vehicle distance based on that the distance to the preceding vehicle is equal to or smaller than the predetermined distance.
