摘要： Vehicle and vehicle tire monitoring system, apparatus and method determine the load-induced deflection or deformation of a vehicle tire and based thereon, deflection-related information, such as tire load, molar air content, total vehicle mass and distribution of vehicle mass, may be provided. The tire deflection region or contact region of the loaded tire is detected by sensing the acceleration of the rotating tire by means of an accelerometer mounted on the tire, preferably on an inner surface such as the tread lining thereof. As the tire rotates and the accelerometer is off of the contact region, a high centrifugal acceleration is sensed. Conversely, when the accelerometer is on the contact region and not rotating, a low acceleration is sensed. The deflection points delimiting the contact region are determined at the points where the sensed acceleration transitions between the high and low values.

摘要： A system for detecting and warning of low air pressure in a vehicle tire which comprises an electrically responsive signaling device actuated by the closure of a pair of electrically conducting contact points secured to an inside surface of the sidewall portion of the tire. The contact points are vertically spaced from one another in a region of the tire wall which flexes in response to loss of air pressure within the tire. Electrical energy is supplied by the vehicle ignition system.

摘要： A tire deterioration inferring (estimating) method uses a tire deterioration inferring device placed on the inner surface of a tire. The method has: a deformation velocity measurement step of measuring a tire deformation velocity, which is the deformation velocity of the tire while the tire is rotating, and obtaining time-series changes in the tire deformation velocity; a calculation step of calculating peak values of the tire deformation velocity from the time-series changes in the tire deformation velocity; and an inference step of inferring the degree of the deterioration of the tire by using a first peak value, which is a peak value of the tire deformation velocity before and at the stepping of the tire or at and after the kicking of the tire, the first peak value being in the time-series changes in the tire deformation velocity.

摘要： A system for measuring the length of the contact patch of a tire mounted on a wheel of a vehicle while the vehicle is traveling that includes a chassis, a light source, a light sensor, a data transmission unit, and a processor. The chassis is attached to the inner side of the tire, and the light source, the light sensor, and the data transmitting unit are attached to the chassis in a way that when the light source illuminates at a specific spot on the inner side of the tire the returning light is detected by the light sensor and the intensity of the returning light can be changed when that specific spot enters the contact patch and when exits the contact patch. The data transmitting unit calculates the length of the contact patch based on intensity changes of the detected light.

摘要： An object of the present invention is to mitigate an influence of a physical quantity other than strain of a tire on a measurement result of a strain sensor and to improve measurement accuracy of the strain sensor. A strain amount detection device according to the present invention calculates an estimation value of a load applied to a tire by using data describing a relationship among an actually measured strain amount, a tire air pressure, a vehicle speed, a tire temperature, and a tire load.

摘要： A disclosed component may include at least one split-ring resonator, which may be embedded within a material. The split ring resonator may be formed from a three-dimensional (3D) monolithic carbonaceous growth and may detect an electromagnetic ping emitted from a user device. The split ring resonator may generate an electromagnetic return signal in response to the electromagnetic ping. The electromagnetic return signal may indicate a state of the material in a position proximate to a respective split ring resonator. In some aspects, the split-ring resonator may resonate at a first frequency in response to the electromagnetic ping when the material is in a first state, and may resonate at a second frequency in response to the electromagnetic ping when the material is in a second state. A resonant frequency of the 3D monolithic carbonaceous growth may be based on physical characteristics of the material.

摘要： Systems and methods of determining tire load from measured tire parameters include using a piezoelectric based sensor to obtain one or more contact patch parameters (e.g., contact patch entry time, contact patch exit time total contact patch time and contact patch angle) and one or more additional sensors to obtain tire pressure. Selected contact patch parameter measurements and pressure values are then compared with known combinations of contact patch parameter values and pressure values stored in a look-up table. A corresponding determined tire load value is then provided as electronic output.
