연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Autonomous cars require the integration of multiple communication systems for driving safety. Many carmakers unveil mirrorless concept cars aiming to replace rear and sideview mirrors in vehicles with camera monitoring systems, which eliminate blind spots and reduce risk. This paper presents optical...

제안 방법

  • Figure 9 shows the results of testing on the real road. Experiments were conducted separately at daytime and nighttime to observe the effect of ambient light. In the figure, the left side shows the rear side vehicle observed from the front vehicle and the right side shows the simulator for analyzing the OCC data.
  • If such an action information of the rear side vehicle can be known in advance by the preceding vehicle, it is possible to anticipate the action of the surrounding vehicle in advance and help the safe running. In this experiment, the data of future vehicle operation plan was transmitted from the LED light source of the rear side vehicle to the front vehicle via OCC link. At this time, not only the information about the action of the vehicle but also information about the type of the vehicle can be sent together to help a safer driving.
  • The object of this paper is to evaluate the potential use of OCC-based V2V systems for mirrorless vehicles. In this study, we carried out experiments on OCC-based V2V communications using 4 types of vehicle action schedule, i.e. running, overtaking, cutting in, and caution, and vehicle type data at daytime and nighttime, respectively. Experimental results show that optical V2V communications for mirrorless cars can transmit OCC data successfully and can be an alternative technology for safety driving.

대상 데이터

  • Based on this, it is possible to prevent accidents by informing the front vehicle ahead of time when the rear vehicle overtakes or drives drowsy. The object of this paper is to evaluate the potential use of OCC-based V2V systems for mirrorless vehicles. In this study, we carried out experiments on OCC-based V2V communications using 4 types of vehicle action schedule, i.

이론/모형

  • LED light sources can offer both communication and illumination performance. Because the human eye cannot perceive the light pulses blinking at 200 Hz or higher frequency, a Manchester encoding method with a flickering rate of greater than or equal to 200 Hz was used. As shown in Figure 4, we set a data frame consisting of 8 bits of preamble and 16 bits of information data.
