Abstract:
1. An inter-vehicle communication and warning apparatus including a forward radar and a backward radar, wherein a host vehicle and a preceding vehicle perform an inter-vehicle communication/detecting via the following model: said forward radar on said host vehicle, with an amplitude shift keying (ASK) for data modulation, transmits forward continuous modulated waves FCRW toward said preceding vehicle, the reflected FCRW, referred to RFCRW from said preceding vehicle are back into said forward radar of said host vehicle, thereby the relative distance and velocity of said host vehicle with respective to said preceding vehicle being computed; and said FCRW are received by said backward radar of said preceding vehicle via an inter-vehicle radio communication channel, through said ASK demodulation, said backward radar of said preceding vehicle obtains the traffic information and transmits a backward continuous modulated wave BCRW to communicate with said host vehicle, and the reflected BCRW, referred to RBCRW, from said host vehicle then transmits back into said backward radar of said preceding vehicle, thereby completing the full duplex for said inter-vehicle communication and detection.
