Patent number: 7136426Abstract: A vehicle-vehicle communication system includes an in-vehicle wire LAN established in a vehicle. The in-vehicle wire LAN includes a plurality of devices connected by optical fiber links. A terminal for radio vehicle-vehicle communication is connected to the in-vehicle wire LAN by the optical fiber link. The terminal receives an optical digital signal in a predetermined format from the in-vehicle wire LAN. The terminal includes a light controlled oscillator and applies the received optical signal to the light controlled oscillator. The light controlled oscillator outputs a transmission signal of a frequency shifted from a predetermined frequency according to the intensity of the applied optical signal. Thus the terminal generates the transmission signal using FSK-modulation technique without converting the format of the optical signal into another format. The transmission signal is transmitted to a device in another vehicle via radio waves.Type: GrantFiled: December 18, 2001Date of Patent: November 14, 2006Assignees: Denso Corporation, National Institute of Information and Communications TechnologyInventors: Minoru Okada, Yutaka Aoki, Manabu Sawada, Masahiro Kuwabara, Hiroshi Harada, Masayuki Fujise
