Abstract: A power generating device capable of improving efficiency of power generation by rotation of a tire and a tire equipped with the power generating device are provided. The power generating device, which is to be mounted on an interior surface of the tire, includes an oscillator that oscillates by rotation of the tire during vehicular travel to produce electromotive force. A resonance frequency of the oscillator is matched to a frequency corresponding to a change in acceleration at the interior surface of the tire during one revolution of the tire rotating at a constant speed.

Abstract: In order to provide a functional component attaching member of which durability can be further improved because when a load is applied to a functional component while a vehicle is travelling, the load can also be borne by portions other than a wall portion opposite to a load direction, the present invention provides a rubber functional component attaching member (functional component mounting base 1) for fastening a functional component 29 to an inner surface 70 of a tire, comprising a bottom surface 4 that is fixed to the inner surface 70 of the tire, an attaching portion 2 having a recessed portion 2A to which a functional component-side attaching portion 30 provided to the functional component 29 is attached, and a reinforcing material 20 embedded in a rubber portion on an outer side of the recessed portion 2A.

Abstract: The invention provides an apparatus, program, and method for controlling the automatic spraying of an antifreezing agent that can reduce the cost of the antifreezing agent and the impact of salt damages caused by the antifreezing agent. This is accomplished by reducing the amount of antifreezing agent to be sprayed automatically according to road surface condition and reducing the amount of the antifreezing agent left unused on completion of the spray operation by grasping in advance the total spray amount of the antifreezing agent.

Abstract: In order to provide a functional component mounting base having high durability to an inertial force acting on a functional component when a tire engages with and disengages from the road surface and to an impact force acting on the functional component mounting base when the tire passes over bumps the functional component mounting base (1) is formed of a rubber material, is attached to an inner surface (70) of the tire to mount the functional component (29) on the inner surface (70) of the tire, and characterized by being provided with a fitting recess (2) into which a functional component-side attaching portion (30) provided on the functional component (29) is fitted.

Abstract: When an electromagnetic generator 10 having a pendulum structure is mounted on an interior surface of a tire 20, an equivalent pendulum length l of a pendulum 14 is adjusted such that an integral multiple of a period ? of the pendulum 14, which is determined by the equivalent pendulum length l of the electromagnetic generator 10, is not in agreement with both of an integral multiple of a circumferential length L of the tire 20 and a length S of a non-grounded part of the tire, which is obtained by subtracting a ground contact length C from the circumferential length L of the tire 20, whereby the power generation capacity of the electromagnetic generator mounted on the tire can be improved regardless of the type of the tire.

Abstract: An in-wheel motor system for mounting a direct drive motor to a steering wheel comprises a first knuckle 4 which is connected to the non-rotary side of a geared motor 3 by a connection member I0 having elastic bodies and direct-moving guides for limiting movement to a vertical direction and locked in a steering direction by upper and lower suspension arms 5a and 5b and a second knuckle 7 which is connected to a steering rod 8 and fitted with a brake unit 9 and a wheel 2 through a hub 6. This second knuckle 7 is connected to the above first knuckle 4 in such a manner that it can turn on a king pin axis J in the steering direction and to the output shaft of the above geared motor 3 by a connection shaft 20 having constant velocity joints 21 and 22 at both ends, thereby reducing an increase in steering torque.

Abstract: Deformation of a tire is measured by a paired sensor 11 consisting of a 1st and 2nd strain gauges positioned on an inner liner of a tire with sensors mounted therein located equally spaced from and symmetrically with the center in an axial direction. Peak values of deformation speeds at the time of entering into the leading edge occurring at the time when the tire tread enters into the contact portion with a road surface are detected from the deformation wave from by differentiating with respect to time the wave form detected by the paired sensor and thus obtained peak values are designated as indication of deformation speed. Then, based on the ratio of thus obtained deformation wave indication and the Map 15M containing relation between thus obtained deformation speed ratio and time slip angle obtained beforehand, the slip angle of a vehicle under running condition is estimated, thereby enabling estimation of tire slip angle under vehicle running accurately.
