Abstract

PURPOSE:To prevent slipping caused by a hydroplaning phenomenon by attaching a sensor for measuring a water condition on the ground to a tire and reporting an increase in a slipping danger to a passenger. CONSTITUTION:Positive and negative electrodes 1 and 2 are buried in a ground so as to be kept within the range of a contact surface of a tire at the time of stop. When electricity flows across these electrodes for over a specified time, a water layer is formed between the tire and the ground and the likelihood of slipping by a hydroplaning penomenon is identified. Then, a danger signal is sent to a driver in the car by a wiring 7. Thus, a slipping danger by the hydroplaning phenomenon can be reported to a driver and safe driving can be maintained.

Slip on rain roads is said to occur due to the so-called hydroplaning phenomenon, which creates a layer of water between the tire and the ground. The present invention is to install a sensor for measuring the state of the ground contact surface on the tire, when the ground contact surface of the tire is in a certain condition, notify the driver of that, or by automatically decelerating the speed of the vehicle, It is intended to prevent slipping due to the hydroplaning phenomenon. It is also possible to attach various inspection devices to the tire to notify the driver of the tire air pressure, the wear state, the temperature, the presence or absence of a puncture warning, and the like. The following is a bulleted description.

（イ）停車時における、タイヤの表面の、接地面に納ま
る範囲に、正の電極１と、負の電極２を埋める。図１に
おいて、正と負の位置は逆でも構わない。(A) The positive electrode 1 and the negative electrode 2 are buried in the range of the surface of the tire that fits in the ground contact surface when the vehicle is stopped. In FIG. 1, the positive and negative positions may be reversed.

ると判断出来る。(B) When the tire rotates and the positive and negative electrodes are grounded, and when a certain amount of electricity flows to the two electrodes, a layer of water is created between the tire and the ground, and hydroplaning is performed. It can be judged that slip due to the phenomenon is likely to occur.

（ハ）タイヤから室内へ通じている配線３によって危険
信号を送り、運転者に知らせる。(C) A danger signal is sent by the wiring 3 that leads from the tire to the interior of the vehicle to notify the driver.

（ニ）タイヤから室内へ配線３によって危険信号を送る
方法以外に、タイヤに取り付けた送信機で危険信号を送
り、その信号を受信機で受取つて対応する方法もある。(D) In addition to the method of sending a danger signal from the tire to the room through the wiring 3, there is also a method of sending a danger signal with a transmitter attached to the tire and receiving the signal with a receiver.

上記の２つの電極による方法のほかに、以下の方法も可
能である。In addition to the above method using two electrodes, the following method is also possible.

（ホ）タイヤに、１個又は数個の、対になった音波発信
装置と受信装置を設置する。音波発信装置は一定の波長
の音波を発信し、受信装置は地面から反射したその音波
を探知する。(E) One or several paired sound wave transmitters and receivers are installed on the tire. The sound wave transmission device transmits a sound wave of a certain wavelength, and the reception device detects the sound wave reflected from the ground.

（ヘ）受信装置と地面の間に水の層があると、受信装置
は音波を探知しない。(F) If there is a layer of water between the receiver and the ground, the receiver will not detect sound waves.

（ト）音波を探知した受信装置の数によって、タイヤの
接地状態を知ることができる。(G) The ground contact state of the tire can be known from the number of receiving devices that have detected the sound waves.

（チ）音波を探知した受信装置の数、すなわちタイヤの
接地面積が、一定の大きさを下回った時に、（ハ）また
は（ニ）の方法により対応する。(H) When the number of receiving devices that detect sound waves, that is, the ground contact area of the tire falls below a certain size, the method (c) or (d) is used.

（リ）音波発信装置の代わりに、光発信装置、またはレ
ーザー発信装置でも良く、その場合は、受信装置はそれ
ぞれ光、レーザーを探知する。(I) Instead of the sound wave transmission device, an optical transmission device or a laser transmission device may be used, in which case the reception device detects light and laser, respectively.
