1. A V2X communication apparatus comprising:
- a message transceiver for receiving a V2X communication message and transmitting V2X data to an apparatus in a vehicle;
a parameter calculator for calculating a reliability verification parameter for verifying reliability of the V2X data;
a reliability level decider for deciding a reliability level by comparing the reliability verification parameter with a predetermined reference value; and
a message generator for generating the V2X data including the deciding reliability level using the V2X communication messagewherein the reliability level decider sets the reliability level to a first reliability level corresponding to a guidance level, a second reliability level corresponding to a warning level, and a third reliability level corresponding to a control level, andwherein the reliability level decider sets reliability of the first reliability level to be lowest among the first, second and third reliability levels, and sets reliability of the third reliability level to be highest among the first, second and third reliability levels.

13. A V2X communication system comprising:
-
a V2X communication apparatus for generating V2X data on the basis of a V2X communication message when the V2X communication apparatus generating V2X data receives the V2X communication message from a surrounding vehicle, deciding a reliability level for the V2X data, and transmitting the V2X data including the decided reliability level to an apparatus in a vehicle; and a plurality of vehicle apparatuses for performing at least one of vehicle guidance, warning, and control by determining whether or not the V2X data are used by checking the reliability level of the V2X data when the plurality of vehicle apparatuses receive the transmitted V2X data, wherein the V2X communication apparatus sets the reliability level to a first reliability level corresponding to a guidance level, a second reliability level corresponding to a warning level, and a third reliability level corresponding to a control level, and wherein the V2X communication apparatus sets reliability of the first reliability level to be lowest among the first, second and third reliability levels, and sets reliability of the third reliability level to be highest among the first, second and third reliability levels. - View Dependent Claims (14, 15)

16. A method for verifying reliability of V2X data, comprising:
-
receiving a V2X communication message from a surrounding vehicle; calculating a reliability verification parameter for verifying the reliability of the V2X data generated on the basis of the V2X communication message; deciding a reliability level by comparing the reliability verification parameter with a predetermined reference value; and allowing the decided reliability level to be included in the V2X data and transmitting the V2X data including the decided reliability level to an apparatus in a vehicle, wherein in the step of deciding of the reliability level, the reliability level is decided to be one of a first reliability level corresponding to a guidance level, a second reliability level corresponding to a warning level, and a third reliability level corresponding to a control level, and wherein in the step of deciding of the reliability level, the reliability level is decided to be the first reliability level to be lowest among the first, second and third reliability levels, and sets reliability of the third reliability level to be highest among the first, second and third reliability levels.
