ようとしている状況であるとして警報を発するようにし
た車両用盗難防止装置が知られている。(Prior Art) Conventionally, as described in, for example, Japanese Utility Model Application Publication No. 62-178529, a predetermined signal such as an ultrasonic wave is transmitted into the vehicle interior with all doors closed. is received inside the vehicle, the level (strength) of the received signal is compared with a preset reference value, and if it does not match the reference value, the vehicle is designed to issue an alarm indicating that the vehicle is about to be stolen. anti-theft devices are known.
上記盗難防止装置は、全てのドアが閉じられた車室内（
密閉空間）においては一定のレベルの信号を送信した場
合受信信号のレベルは常に一定の値になり、もしドアが

その基準値と比較し、基準値と異なれば車室内の密閉空
間状態が破られ、盗難されようとしていると判断し、警
報を発するものである。The above anti-theft device is installed inside the vehicle with all doors closed (
If a signal of a certain level is transmitted in a closed space, the level of the received signal will always be a constant value, but if a door is opened or a window is broken, the level of the received signal will change accordingly. In consideration of this, the above-mentioned constant value is set in advance as a reference value, and the level of the received signal is compared with the reference value. If it differs from the reference value, the sealed space inside the vehicle has been broken and the vehicle is about to be stolen. It makes a judgment and issues a warning.

果誤警報が発せられるという問題がある。(Problem to be Solved by the Invention) However, in the conventional theft prevention device described above, the reference value for comparing the received signal level is set as one fixed value corresponding to the level of the transmitted signal, and as a result, an error occurs. The problem is that an alarm is raised.

の結果受信信号のレベルが基準値と一致しないというこ
とで誤って警報を発してしまうことがある。That is, in a sealed vehicle interior, a transmitting means and a receiving means are originally provided at a fixed location, and if the transmitting means transmits a signal of a fixed level, the received signal received by the receiving means will always be at a fixed level. However, for example, if there is a large baggage inside the vehicle, or if the area where the vehicle is parked is extremely noisy, the level of the received signal will change depending on these factors, and as a result, the level of the received signal will change. An alarm may be issued erroneously because the level does not match the reference value.

されるものを採用することができる。First, the bar glass setting is performed by the bar glass setting means 8 at Sl. This bar glass set may be performed in any manner, but for example, in the case of a four-door vehicle, each door is provided with a door close and lock detection device, and all three doors other than the driver's side are closed. It is possible to adopt a system in which the driver's seat door is locked, and then the driver's seat door is closed, and the bar glass is set when the driver's seat door is locked with the key.

セット後複数回送受信を行ない、その複数回の受信信号
のレベルの平均値を基準値として記憶しても良い。After the above-mentioned bar graph setting is performed, the transmitting means 4 and the receiving means 6 are activated in S2 and S3, and the reference value is stored in the storage means 12 in S4. This reference value storage may be performed as long as it is performed at the time of setting the bar glass, and in a specific embodiment, for example, the first signal transmitted by the transmitting means 4 after setting the bar glass is received by the receiving means 6, and the level of the received signal is set to the reference value. Alternatively, transmission and reception may be performed a plurality of times after the par-glas setting, and the average value of the levels of the received signals of the plurality of times may be stored as the reference value.
バーグラセット後は上記送信手段４および受信手段６に

レベルと基準値とを比較し、一致すればまたＳ５．Ｓ６
゜Ｓ７を繰り返し、不一致の場合はＳっで警報を発する
。After the bar graph is set, the transmitting means 4 and the receiving means 6 perform transmission and reception at predetermined intervals, and once the reference value is memorized by the first transmission and reception or multiple transmissions and receptions as described above, each subsequent transmission and reception The level of the received signal is then compared with the above reference value, and if the two do not match, an alarm is issued. That is, S5. Transmission and reception are performed in S6, and the received signal level is compared with the reference value in S7. If they match, the process is repeated in S5. S6
゜Repeat S7, and if there is a discrepancy, issue an alarm with S.
上記基準値は一点の値でも良いし、所定の幅を有するも

内に入っていれば一致と判断すれば良い。The above reference value may be a value at one point, or it may be set as a value with a predetermined width (a value with a predetermined width added to the received signal level or average value at the time of the bar graph setting). If the signal level is within the range of the reference value, it may be determined that they match.
また、上記警報発生は、例えばクラクションを鳴らした

ことなく、常に正確な警報発生が行なわれる。According to the anti-theft device configured as described above, the reference value is set for each bar glass set according to the situation at the time of the bar glass set, so even if there is luggage in the vehicle interior or the surrounding noise is loud, the reference value is set for each bar glass set depending on the situation. Appropriate standard values are set accordingly. Therefore, accurate alarm generation is always performed without being affected by luggage in the vehicle interior, surrounding noise, etc.
