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.

A transmitter at a lead vehicle transmits a first transmission signal toward a first beacon and a second beacon associated with a following vehicle. A data processor or estimator determines a first propagation time associated with the first transmission and the first beacon and a second propagation time associated with the first transmission and the second beacon. A vehicle controller controls a heading of the following vehicle to maintain a first distance substantially equal to a second distance (i.e., first propagation time substantially equal to a sec...

The following is claimed: 1. A method for following of a lead vehicle with a following vehicle, the method comprising: transmitting a first transmission signal from a transmitter at a lead vehicle toward a first beacon associated with a following vehicle; communicating between the first beacon and a second beacon spaced apart from the first beacon by a known distance; transmitting a second transmission signal from the second beacon to the lead vehicle; determining a first elapsed time between the transmission of the first transmission signal to a first beacon; determining a second elapsed time between the transmission of the second transmission signal from the second beacon to the lead vehicle; converting the first elapsed time into a first distance between the transmitter and the first beacon; converting the second elapsed time into a second distance between the transmitter and the second beacon; and controlling a heading of the following vehicle to maintain a first distance substantially equal to a second distance; and controlling a speed of the following vehicle to maintain at least one of a desired first distance and a desired second distance. 2. The method according to claim 1 wherein the controlling further comprising tracking a lead heading of the leading vehicle with a following heading of a following vehicle with a delay based on at least one of the speed and acceleration of the lead vehicle. 3. The method according to claim 1 further comprising: determining a global position of the lead vehicle based at least partially on a reception of a group of satellite signals; determining a global position of the following vehicle based at least partially on a reception of a group of satellite signals; recording a registration of a leading heading of the lead vehicle with the respective global position; controlling the following heading of the following vehicle to match that of the lead vehicle at the respective global position provided that the leading vehicle and following vehicle maintain a minimum separation. 4. A system for following of a lead vehicle with a following vehicle, the system comprising: a transmitter for transmitting a first transmission signal from a transmitter at a lead vehicle toward a first beacon and a second beacon associated with a following vehicle, the first beacon and second beacon separated by a known distance; an estimator for determining a first aggregate elapsed time between the transmission of the first transmission signal to a first beacon and a return signal from the first beacon to the lead vehicle, the estimator arranged to determine a second aggregate elapsed time between the transmission of the first transmission signal to a second beacon and a return signal from the second beacon to the lead vehicle; a converter for converting the first aggregate elapsed time into a first distance between the transmitter and the first beacon and for converting the second aggregate elapsed time into a second distance between the transmitter and the second beacon; and a vehicle controller for controlling a heading of the following vehicle to maintain a first distance substantially equal to a second distance, wherein the vehicle controller controls a speed of the following vehicle to maintain at least one of a desired first distance and a desired second distance. 5. The system according to claim 4 wherein the vehicle controller tracks a lead heading of the leading vehicle with a following heading of a following vehicle with a delay based on at least one of the speed and acceleration of the lead vehicle. 6. The system according to claim 4 further comprising: a first location determining receiver for determining a global position of the lead vehicle based at least partially on a reception of a group of satellite signals; a second location determining receiver for determining a global position of the following vehicle based at least partially on a reception of a group of satellite signals; a data storage device for recording a registration of a leading heading of the lead vehicle with the respective global position; a following vehicle controller for controlling the following heading of the following vehicle to match that of the lead vehicle at the respective global position provided that the leading vehicle and following vehicle maintain a minimum separation. 7. A system for following of a lead vehicle with a following vehicle, the system comprising: a transmitter for transmitting a first transmission signal from a transmitter at a lead vehicle toward a first beacon associated with a following vehicle; a wireless communications device for communicating between the first beacon and a second beacon spaced apart from the first beacon by a known distance; a transceiver for transmitting a second transmission signal from the second beacon to the lead vehicle; an estimator for determining a first elapsed time between the transmission of the first transmission signal to a first beacon and for determining a second elapsed time between the transmission of the second transmission signal from the second beacon to the lead vehicle; a converter for converting the first elapsed time into a first distance between the transmitter and the first beacon and for converting the second elapsed time into a second distance between the transmitter and the second beacon; and a vehicle controller for controlling a heading of the following vehicle to maintain a first distance substantially equal to a second distance, wherein the vehicle controller controls a speed of the following vehicle to maintain at least one of a desired first distance and a desired second distance. 8. The. system according to claim 7 wherein vehicle controller comprises tracking a lead heading of the leading vehicle with a following heading of a following vehicle with a delay based on at least one of the speed and acceleration of the lead vehicle. 9. The system according to claim 7 further comprising: a first location determining receiver for determining a global position of the lead vehicle based at least partially on a reception of a group of satellite signals; a second location determining a global position of the following vehicle based at least partially on a reception of a group of satellite signals; a data storage device for recording a registration of a leading heading of the lead vehicle with the respective global position; a following vehicle controller for controlling the following heading of the following vehicle to match that of the lead vehicle at the respective global position provided that the leading vehicle and following vehicle maintain a minimum separation. 10. A method for following of a lead vehicle with a following vehicle, the method comprising: transmitting a first transmission signal toward a first beacon and a second beacon associated with a following vehicle; determining a first propagation time associated with the first transmission and the first beacon and a second propagation time associated with the first transmission and the second beacon; controlling a heading of the following vehicle to maintain a first propagation time substantially equal to the second propagation time for straight or a linear path segment and controlling a heading of the following vehicle to maintain the first propagation time that deviates from the second propagation time by a predetermined maximum amount for a curved path or turn.
