1. A vehicle control device, comprising:
a receiving unit configured to receive emergency vehicle driving information including at least one of location information, path information, speed information, or driving lane information for an emergency vehicle;
a driving lane identification unit configured to extract road information for a road on which a vehicle is driving using location information and map information for the vehicle and obtain driving lane information for the vehicle based on sensor information obtained from a sensor of the vehicle; and
a driving controller configured to determine whether the emergency vehicle and the vehicle travel in the same lane using the emergency vehicle driving information and the driving lane information for the vehicle and control to vary at least one of a set speed value or a set inter-vehicle distance of a driving assist system applied to the vehicle and activated based on a result of the determination,
wherein when it is determined that the emergency vehicle and the vehicle travel in different lanes, the driving controller determines a variable parameter of the driving assist system applied to the vehicle and activated, as at least one of a set speed value or a set inter-vehicle distance, based on a driving lane difference value between the emergency vehicle and the vehicle,
wherein when it is determined that the driving lane of the vehicle is a lane next to the driving lane of the emergency vehicle, the driving controller controls to increase the set inter-vehicle distance to a preceding vehicle in the driving lane of the driving assist system applied to the vehicle and activated,
wherein when it is determined that the emergency vehicle and the vehicle travel in the same lane and a distance to a point where a driving road needs to be changed based on a set driving path in the vehicle is within a predetermined distance, the driving controller selects a target lane to be changed from the same lane, based on a direction in which the driving road is changed, and
wherein a first inter-vehicle distance which is varied when the vehicle travels in the lane next to the driving lane of the emergency vehicle and a second inter-vehicle distance which is varied when the driving lane difference value is two or more lanes are set to differ from each other.
