1. A vehicle control comprising:
- a vehicle to everything (V2X) terminal configured tocollect driving information from vehicles,transmit a transmission message to roadside equipment (RSE), andgenerate control data and display datawherein the RSE analyzes the number of vehicles within a management section, position information, and speed information from the driving information and transmits a reception message about driving limit information including a speed limit of the management section and neighboring vehicle information to at least a vehicle,wherein the V2X analyzes the driving limit information from the RSE and converts the driving limit information to control data and display data;
an integrated controller configured toreceive the control data,calculate a deceleration level, andgradually decelerate a speed of a vehicle to be less than or equal to the speed limit based on the calculated deceleration level; and
an interface unit configured to receive the display data, and to transmit the received display data to an audio/video/navigation (AVN) system capable of displaying a warning notification for a driver, wherein the management section comprises subsections for the setting of speed limits in the management section.

Abstract
Disclosed are an automatic speed controllable vehicle and a speed controlling method thereof. The vehicle collects vehicle information and transmitted collected vehicle information to an RSE, and the RSE receives vehicle information from each vehicle within a management section and transmits again, to each vehicle, information required for each vehicle to adjust a speed. The vehicle receiving information required to adjust the speed may adjust the speed of the vehicle based on the received information and may display a warning notification for a driver.

9. A method of controlling a speed of at least one vehicle configured to perform communication with Road Side Equipment (RSE) using a Wireless Access in Vehicular Environments (WAVE) communication, the method comprising:
-
collecting, by each of the at least one vehicle, driving information including speed information and position information of a vehicle, generating a transmission Basic Safety Message (BSM) corresponding to a WAVE communication format, and transmitting the transmission BSM to the RSE; receiving, by each of the at least one vehicle, a reception BSM that is transmitted from the RSE by analyzing the number of vehicles within a management section and driving information of each of the at least one vehicle, and by including driving limit information and neighboring vehicle information; and obtaining, by each of the at least one vehicle, a speed limit of the management section included in the driving limit information and the neighboring vehicle information, calculating a deceleration level based on a current speed of a vehicle exceeding the speed limit and the speed limit, and decelerating the speed of the vehicle based on the calculated deceleration level, wherein the management section comprises subsections for the setting of speed limits in the management section. - View Dependent Claims (10, 11, 12, 13)
