SYSTEM AND METHOD OF DETECTING INTRUSION INTO VEHICLE

摘要

A system and a method of detecting an intrusion into a vehicle includes: a transmitter that transmits an ultrasonic wave signal into the vehicle when the system enters an intrusion-into-vehicle monitoring mode; a receiver that receives an ultrasonic wave signal reflected by an object inside the vehicle; and a controller that generates an intrusion warning when it is detected that a frequency level of the ultrasonic wave signal flowing in the receiver is changed, determines that a frequency by an external ultrasonic wave device is synthesized when a changed frequency waveform having a predetermined magnitude is continuously received by the receiver, and defers generation of the intrusion warning.

1. A system for detecting an intrusion into a vehicle, comprising:
a transmitter configured to transmit an ultrasonic wave signal into the vehicle when the system enters an intrusion-into-vehicle monitoring mode; a receiver configured to receive the ultrasonic wave signal reflected by an object inside the vehicle; and a controller configured to generate an intrusion warning when it is detected that a frequency level of the ultrasonic wave signal flowing in the receiver is changed, determine that a frequency by an external ultrasonic wave device is synthesized when a changed frequency waveform having a predetermined magnitude is continuously received by the receiver, and defer generation of the intrusion warning.
