摘要： The present invention provides a tire distortion detecting method, a distortion detector, and a tire which can reduce the occurrence of a deterioration and can be used for a control system such as a stability control system. That is, series of conductors composed of a plurality of conductor pieces 101 and 102 are provided in two different layers. The conductor pieces 101 and 102 are embedded in lines at predetermined intervals in the circumferential direction of a tire 300. A pulsed electromagnetic wave is radiated to the surfaces of metal foils 101 and 102 in the layers from a monitoring device 200 provided in a tire house 400 of a vehicle. The monitoring device 200 receives a pulsed electromagnetic wave reflected from the metal foils 101 and 102 in the layers or a member other than the metal foils. Time from the radiation of a pulsed electromagnetic wave to the reception of a reflected pulsed magnetic wave is measured repeatedly, time at which no distortion occurs on the tire 300 is stored as a reference value, and the measured time and the stored reference value are compared with each other to detect a distortion of the tire 300.

摘要： Energy for in-tire use is generated from the load induced reciprocating deflection of the tire inner walls above the tire-to-road contact patch adjacent to the shoulder of the tire. This energy is used to power in-tire monitoring electronics. For pulsatile energy generation with capacitive capture, the capacitor is optimally selected in real-time as a function of pulse width to maximize energy capture, or as a function of the pulse-captured energy. The resulting energy pulses are also used to measure the time duration of the contact patch from which the contact patch length is determined thus providing real-time tire geometry and, with tire pressure, real time tire load and, with temperature, tire air molar content. The loads on all tires provide real time vehicle mass and mass distribution. For electrical energy generation, magnet-coil, piezo-electric, and other power conversions are applicable. For non-electric energy generation, fluid bellows, rotary pump, and other power conversions are applicable. Further, run flat tires are designed with a cutout to accommodate and protect electronic devices mounted on an inner surface when running flat.

摘要： A sensor is provided for detecting rotations of a pneumatic tire on a vehicle comprising two spaced apart mounting points for attachment to the radially inner surface of the tire tread region, a contact member between the mounting points for contacting the inner surface of the tread radius of the tire between the two mounting points and signal producing means comprising a piezo-electric device which is adapted to produce a signal when the contact member is moved radially of the tire relative to the two mounting points wherein damping means are provided so that a signal is generated when the movement occurs rapidly but slow movement generates no signal so that on rotation of the tire on a vehicle a signal is produced each time the tread region to which the sensor is attached becomes changed in radius at the contact patch of the tire but when the tread radius changes slowly when there is a pressure change in the tire and the movement is slow no signal is produced.

The power generation body includes a first member and a second member. The first member has a first insulating film forming a first surface. The second member has a second insulating film forming a second surface that faces the first surface and contacts the first surface. The elastic body biases the power generation body toward the inner surface of the tire.

摘要： A maximum friction coefficient estimation system includes a storage unit and a maximum friction coefficient calculation unit. The storage unit stores a table or a function for calculating a maximum friction coefficient between a tire and a road surface for a representative tire, based on a speed of rolling motion, load, temperature of the tire and a road surface condition level. The maximum friction coefficient calculation unit corrects the table or the function according to an individual tire specification and calculates the maximum friction coefficient.
