Method and apparatus for detecting intrusion into large vehicle
First Claim
1. A method for detecting a vehicle intrusion, the method comprising:
- a first signal transmission process for alternately transmitting a first signal of a waveform through a first transmission module and a second transmission module at a predetermined period;
a first intrusion determination process for analyzing a reflected wave received in response to the transmitted first signal to determine whether the intrusion occurred;
a second signal transmission process for transmitting a second signal of a pulse waveform, upon detecting the intrusion as a result of the first intrusion determination process;
a second intrusion determination process for analyzing a waveform of a reflected wave received in response to the transmitted second signal to determine whether the intrusion occurred; and
transmitting a predetermined alarm message indicating that the intrusion occurred upon detecting the intrusion as a result of the second intrusion determination process.

9. A vehicle intrusion detection apparatus, comprising:
-
a pulse generator for generating a pulse waveform signal with a predetermined transmission period; first and second transmission modules for amplifying and transmitting the generated pulse waveform signal; a reception module for receiving a reflected wave received in response to the transmitted pulse waveform signal; a communication processor for communicating with an external apparatus; and a controller for performing a control to alternately transmit the pulse waveform signal through the first and second transmission modules at a predetermined period and for determining whether an intrusion occurred based on a change in a waveform of the received reflected wave, wherein the determination, by the controller, of whether the intrusion occurred, comprises a first intrusion determination process and a second intrusion determination process, and in the first intrusion determination process, upon detecting the intrusion, the controller identifies a transmission module related to the occurred intrusion and activates only the identified transmission module to transmit the pulse waveform signal through only the identified transmission module and performs the second intrusion determination process and analyzes a waveform of a reflected wave received in the second intrusion determination process to determine whether the intrusion occurred, and in the second intrusion determination process, upon detecting the intrusion, the controller transmits a predetermined alarm message, indicating that the intrusion occurred, to a vehicle controller through the communication processor. - View Dependent Claims (10, 11, 12, 13, 14)
