摘要： The dynamic state amount of a tire when a load is applied to the tire while running can be estimated accurately and stably by installing tire deformation amount measuring means 11A and 11B at axisymmetrical positions which are equally distant in the axial direction from the center in the axial direction of the tire on the cross-section in the radial direction of the tire on the inner side of the belt portion of a tire tread in the radial direction, such as at the inner surface of the tread, between an inner liner and a ply, between plies or between a ply and a belt to measure the waveforms of deformation of the tire, detecting the contact time which is the time difference between contact edges from the waveforms of deformation, calculating contact length indices kA and kB from the contact time and the wheel speed detected by a wheel speed sensor 15, calculating the average value k of the above indices kA and kB, and obtaining a load applied to the tire by using the calculated average value k of the indices of contact length and a map 18M showing the relationship between the average value of the indices of contact length and load pre-stored in memory means 18.

摘要： An intra-tire power generating apparatus capable of producing high power is provided. The apparatus includes rotary magnets and rotary weights, which rotate in response to variations in centrifugal force and circumferential acceleration working on the tire of a running vehicle, and a coil unit, which is located between two rotary magnets facing each other and generates voltages through electromagnetic induction from the rotary magnets. In the apparatus, the rotary magnets and the rotary weights have an identical center line of rotation. The rotary weights are so formed as to have their center of gravity dislocated from the center line of rotation. The rotary magnets are each provided, in the plane orthogonal to the center line of rotation, with an even number of regions adjoining in the circumferential direction around the center line of rotation, the adjoining regions having different magnetic poles from each other. The two rotary magnets facing each other are so configured as to rotate while maintaining the opposition of their respective regions having mutually opposite magnetic poles. And the coil unit has coil windings, each of which is of a tubular shape surrounding a space through which the magnetic flux generated between the mutually opposite magnetic poles of the two rotating rotary magnets passes.
