METHOD AND SYSTEM FOR INTELLIGENT SAFE CAR NAGIVATION BY USING OF ADAPTIVE COMMUNICATION TECHNOLOGY

摘要

An intelligent car navigation method and system using adaptive communication technology are provided to prevent a series-crash accident by quickly notifying abnormal state of a vehicle or an accident to other vehicles. A sensor(101) is either an impact sensor or a gyroscope. An ECU(Engine Control Uni,102) and an ACU(Automatic Control Unit,103) are mounted on a vehicle and connected to a controller(105) to transmit state information to the controller. A GPS(Global Positioning System,104) detects position and moving direction of the vehicle. An I/O device(106) and a speaker(107) interface with a user and include a display device or a key button. A transceiver modem(108) delivers an accident signal from the controller to an RF(Radio Frequency) transmitter(109) or delivers the signal from an RF receiver(110) to the controller. The RF transmitter changes frequency at an arbitrary timing within a predetermined frequency band and transmits signals at the changed frequencies. The RF receiver receives all signals within the predetermined frequency band.
