First Claim
Patent Images
1. A vehicle comprising:
- a vehicle to everything (V2X) terminal configured to collect driving information, to transmit a transmission message to roadside equipment (RSE), and to generate control data and display data by analyzing and converting driving limit information when 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 the driving limit information including a predetermined speed limit and neighboring vehicle information;
an integrated controller configured to receive the control data, to calculate a deceleration level, and to gradually 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.

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 RSE using a 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 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 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. - View Dependent Claims (10, 11, 12, 13)
