Device and method for controlling vehicle
According to the disclosure, there may be provided a vehicle control device and method and, in particular, a vehicle control device and method that allows an emergency vehicle to smoothly travel without disturbance by other vehicles by analyzing the location and driving lane of the emergency vehicle and providing a notification to vehicles in the same lane as the emergency vehicle according to a predetermined condition when the emergency vehicle approaches and allowing the vehicles to change their driving lane or to change preset variable parameter values of the driving assist system applied to the vehicle and activated.
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.
2. The vehicle control device of claim 1 , wherein the driving controller selects the target lane to which the lane in which the vehicle is driving is to be changed using at least one of inter-vehicle distance information, speed information, or traffic information for an expected target lane.
3. The vehicle control device of claim 1 , wherein the driving controller determines the variable parameter as the set inter-vehicle distance and controls to increase the set inter-vehicle distance if the difference value falls within a preset first reference range, and the driving controller determines the variable parameter as the set speed value and controls to decrease the set speed value if the difference value falls within a preset second reference range.
4. The vehicle control device of claim 1 , wherein when it is determined that the emergency vehicle and the vehicle travel in different lanes, the driving controller controls to decrease a set speed value of the driving assist system applied to the vehicle and activated.
5. The vehicle control device of claim 1 , wherein when the driving assist system applied to the vehicle and activated performs braking control on the vehicle, the driving controller controls to further vary a set operation sensitivity applied to the driving assist system.
6. The vehicle control device of claim 1 , wherein the driving controller calculates a distance between the emergency vehicle and the vehicle and, if it is determined that the calculated distance is a set value or less, provides a notification to the vehicle in front of the emergency vehicle.
7. A vehicle control method, comprising:
receiving emergency vehicle driving information including at least one of location information, path information, speed information, or driving lane information for an emergency vehicle;
extracting lane information for a road on which a vehicle is driving using location information and map information for the vehicle and obtaining driving lane information for the vehicle based on sensor information obtained from a sensor of the vehicle; and
controlling driving, including determining 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 controlling 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 controlling the driving includes, when it is determined that the emergency vehicle and the vehicle travel in different lanes, determining 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, and
wherein controlling the driving includes,
when it is determined that the driving lane of the vehicle is a lane next to the driving lane of the emergency vehicle, controlling 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, and
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, selecting 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.
8. The vehicle control method of claim 7 , wherein controlling the driving includes:
determining the variable parameter as the set inter-vehicle distance and controls to increase the set inter-vehicle distance if the difference value falls within a preset first reference range; and
determining the variable parameter as the set speed value and controls to decrease the set speed value if the difference value falls within a preset second reference range.
