Vehicle, communication method thereof, and wireless communication device therein

A vehicle comprising:

• a wireless communication unit configured to form a direct beam pattern for performing direct wireless communication with a single target vehicle and configured to form an omnidirectional beam pattern for performing wireless communication with at least two peripheral vehicles;
• a radar module configured to obtain position information of the at least one peripheral vehicle;
• and
• a display unit configured to display the obtained position information,
• wherein,
• when the single target vehicle is selected, by a user, from the at least one peripheral vehicle based on the displayed position information, the direct beam pattern is formed toward the selected single target vehicle,
• when the single target vehicle is not selected, by the user, from the at least one peripheral vehicle based on the displayed position information, the omnidirectional beam pattern is formed to communicate with the at least two peripheral vehicles,
• wherein the wireless communication unit comprises:
• a beam forming module configured to form the direct beam pattern and transceive a wireless signal through a radio wave of the direct beam pattern, and configured to form the omnidirectional beam pattern and transceive a wireless signal through a radio wave of the omnidirectional beam pattern;
• and
• a wireless communication control module configured to control the formation of the direct beam pattern according to a position of the single target vehicle, and
• wherein the wireless communication unit detects again the position of the single target vehicle when it is determined that the single target vehicle is deviated from the direct beam pattern.

A communication method of a vehicle, comprising:

• receiving a selection of a single target vehicle by a user from at least one peripheral vehicle;
• forming a direct beam pattern toward the single target vehicle;
• communicating with the single target vehicle through a radio wave of the direct beam pattern;
• and
• detecting again a position of the single target vehicle when it is determined that the single target vehicle is deviated from the direct beam pattern,
• wherein the forming of the direct beam pattern toward the single target vehicle comprises:
• determining a main direction of the direct beam pattern according to position information of the single target vehicle;
• determining phase differences of wireless signals transmitted through a plurality of unit antennas based on the determined main direction;
• transmitting the wireless signals through the plurality of unit antennas according to the determined phase differences, and
• forming an omnidirectional beam pattern when the single target vehicle is not selected by the user from the at least one peripheral vehicle, and communicating with at least two peripheral vehicles through a radio wave of the omnidirectional beam pattern.

A wireless communication device of a vehicle, comprising:

• an internal communication unit configured to access a communication network of the vehicle;
• a wireless communication unit configured to form a direct beam pattern and communicate with an external device through a radio wave of the direct beam pattern and configured to form an omnidirectional beam pattern and communicate with at least two external device devices through a radio wave of the omnidirectional beam pattern;
• and
• a communication controller configured to control the wireless communication unit to form the direct beam pattern toward a single target vehicle when the single target vehicle is selected, by a user, from at least one peripheral vehicle and when an information transmission request and position information of the single target vehicle through the internal communication unit are received, the communication controller further configured to control the wireless communication unit to form the omnidirectional beam pattern when the single target vehicle is not selected, by the user, from the at least one peripheral vehicle,
• wherein the wireless communication unit comprises:
• a beam forming module configured to form the direct beam pattern and transceive a wireless signal through the radio wave of the direct beam pattern, and configured to form the omnidirectional beam pattern and transceive a wireless signal through the radio wave of the omnidirectional beam pattern;
• a signal conversion module configured to demodulate the wireless signal received through the beam forming module, and modulate a signal transmitted through the beam forming module;
• and
• a wireless communication control module configured to control the formation of the direct beam pattern according to a position of the single target vehicle, and
• wherein the wireless communication unit detects again the position of the single target vehicle when it is determined that the single target vehicle is deviated from the direct beam pattern.
