Abstract
Provided is a method of detecting vehicle misbehavior using a radio wave characteristic. Unlike an existing vehicle misbehavior detection method, according to the method of detecting vehicle misbehavior using a radio wave characteristic, a vehicle does not detect misbehavior or another vehicle, and vehicle misbehavior is detected on the basis of difference between vehicle-related information included in a message transmitted to a vehicle by a road side unit (RSU) and information derived from a radio wave characteristic of a received signal.
Claims7
A method of detecting vehicle misbehavior using a radio wave characteristic performed by a road side unit (RSU) installed at a fixed location on a roadside, the method comprising:
- a first speed acquisition operation of acquiring a first speed of a vehicle which is traveling in a communication coverage from a basic safety message (BSM) received from a vehicle-to-everything (V2X) communication device on board the vehicle;
- a second speed calculation operation of calculating a second speed of the vehicle using a frequency shift caused by a Doppler effect of a signal received from the V2X communication device;
- an anomaly message reception judgment operation of comparing a difference between the first speed and the second speed with a set reference error to determine whether an anomaly message has been received;
- and
- a misbehavior detection (MBD) judgment operation of determining, when a number of anomaly messages received from the vehicle exceeds a set first reference value, the vehicle as misbehaving vehicle to generate a misbehavior report (MBR).
A method of detecting vehicle misbehavior using a radio wave characteristic performed by a road side unit (RSU) installed at a fixed location on a roadside, the method comprising:
- a range calculation operation of calculating a range from a vehicle which is traveling in a communication coverage using a signal transmission time included in a basic safety message (BSM) received from a vehicle-to-everything (V2X) communication device on board the vehicle and a time of signal arrival;
- a vehicle range reception operation of receiving range information of the vehicle, which is calculated by each of two or more neighboring RSUs using a time of signal arrival from the two or more RSUs;
- a vehicle position calculation operation of calculating a position of the vehicle using triangulation on the basis of location information of the RSUs, the calculated range from the vehicle, and the received range information of the vehicle;
- a position error calculation operation of calculating a position error between position information of the vehicle included in the received BSM and the calculated position of the vehicle;
- an anomaly message reception judgment operation of comparing the calculated position error with a reference range error to determine whether an anomaly message has been received;
- and
- a misbehavior detection (MBD) judgment operation of determining, when a number of anomaly messages received from the vehicle exceeds a set first reference value, the vehicle as misbehaving vehicle to generate a misbehavior report (MBR).
