<P>PROBLEM TO BE SOLVED: To provide an automobile anti-theft device using a mobile phone, capable of preventing an automobile theft using a device for generating interfering waves. <P>SOLUTION: The automobile anti-theft device comprises data transmission/reception means 12 mounted on a vehicle, communication abnormality detection means 22 for generating data transmission/reception means abnormality signal when the data transmission/reception means becomes communication abnormal, receiving the interfiring waves and transmission/reception control means 16 for controlling the data transmission/reception means receiving the data transmission/reception means signal from the communication abnormality detection means. The transmission/reception control means 16 uses the data transmission/reception means to generate a first operation signal for transmitting historical signals of receiving interfering waves to outside, when the data transmission/reception means abnormality signal received from the communication abnormality detection means stops. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
