摘要:
An apparatus and method for controlling a vehicle speed based on information about forward vehicles that travel in the same lane may be acquired using Vehicle to Everything (V2X) communications in a cooperative adaptive cruise control (CACC) system. The CACC system includes a communication unit receiving vehicle information from neighboring vehicles using V2V communications; an information collection unit collecting vehicle information of the neighboring vehicles and the subject vehicle using sensors; and a control unit determining a forward vehicle and a far-forward vehicle using the sensors, selecting first and second target vehicles for being followed by the subject vehicle based on the vehicle information of the forward vehicle and the far-forward vehicle and the vehicle information of the neighboring vehicles, and controlling the driving speed of the subject vehicle based on speed information of the first and second target vehicles.

A vehicle and a method for controlling the same are provided to determine a traveling speed based on travel information of a first preceding vehicle and a second preceding vehicle. The vehicle includes a drive unit that provides rotational force for vehicle traveling and a distance sensor that detects an object located in a forward direction. A controller first preceding vehicle and a second preceding vehicle located ahead of the first preceding vehicle, which travel on the same traffic road as a traveling road based on the result detected by the distance sensor. The drive unit is operated to adjust a vehicle speed to be at a traveling speed determined based on travel information of the first preceding vehicle and the second preceding vehicle.

摘要:
A virtual sensor network system is provided that includes a virtual sensor node that stores sensor data collected from a sensor mounted within a vehicle in time synchronization therewith and provides the stored sensor data in time synchronization therewith, in addition, a master node performs a control on the virtual sensor node and executes an algorithm used in an intelligent vehicle using the sensor data. The master node receives the sensor data stored in the virtual sensor node as the virtual sensor data in time synchronization therewith, without inputting actual sensor data from the sensor mounted within the vehicle when executing the algorithm.

摘要:
A technique for controlling power for V2X communication is provided. The apparatus includes a reception message analysis process configured to analyze headers of reception messages received from communication apparatuses of roadside apparatuses and surrounding vehicles located around a vehicle, a message loss checking process configured to check whether or not loss of the reception messages occurs by counting sequential numbers included in the headers of the reception messages, a density analysis process configured to analyze a density for each of communication apparatuses located in a communication radius of preset transmission power from the vehicle when the message loss checking process determines that the loss of the reception messages occurs, and a transmission power determination process configured to determine transmission power for V2X communication by deducting the preset transmission power in units of reference power according to the density when the density around the vehicle exceeds a reference value.

摘要:
An apparatus including a processor configured to: detect a position of a vehicle and a plurality of positions of fixed objects located around the vehicle based on map coordinates; detect objects based on information measured using a distance measurement sensor disposed in the vehicle; detect a moving object among the detected objects; estimate a plurality of positions of the vehicle and the moving object after a fixed period of time based on a position, a speed, and a movement direction of the moving object; and calculate a degree of proximity risk for the moving object with respect to the vehicle based on a distance and a speed between the vehicle and the moving object.
