摘要： A tire groove depth display method includes a grounded part extracting step, a groove depth calculating step, an image generating step, and a displaying step. The grounded part extracting step extracts a grounded part on a surface of a tread part of a tire as a plurality of areas sandwiching a tire groove. The groove depth calculating step calculates a depth of the tire groove between respective areas of the grounded part. The image generating step generates an image that shows the areas extracted by the grounded part extracting step and information on the depth of the tire groove calculated by the groove depth calculating step. The displaying step displays the image generated by the image generating step.

摘要： A counter-deflection load estimation system for a tire is provided. The tire includes a pair of sidewalls extending to a circumferential tread and supporting a vehicle, and the vehicle includes a controlled area network bus. In the system, a sensor is mounted to the tire and measures a parameter of the tire. A counter-deflection of the tire is determined from the measured parameter, and a linear vehicle speed signal is received through the controlled area network bus. A processor is in electronic communication with the sensor and with the controlled area network bus. A load estimation module is in electronic communication with the processor, receives the linear vehicle speed signal and the counter-deflection of the tire, and determines a load on the tire.

摘要： A tire tester includes a plurality of tire holding units attached to a movable member or a towed member and each configured to detachably hold a tire, and one or more load measuring units for measuring a load acting on the tire. The plurality of tire holding units include a first tire holding unit configured to detachably hold a first tire, and one or more second tire holding units each configured to detachably hold a second tire. The second tire holding unit holds the second tire to generate a force opposite to a lateral component force generated by steering the first tire. The tire holding units are arranged such that at least one tire holding unit is disposed on each right and left side of the movable member or the towed member with respect to a center line passing through a lateral center thereof.

摘要： A vehicle information calculation apparatus includes a motor torque acquisition unit, an angular acceleration acquisition unit, a contact force acquisition unit, and an inertia moment calculator. The motor torque acquisition unit acquires a torque of a motor that drives a vehicle. The angular acceleration acquisition unit acquires an angular acceleration of the motor. The contact force acquisition unit acquires a contact force of a wheel of the vehicle. The inertia moment calculator calculates an inertia moment of a rotating system of the vehicle including the wheel on the basis of the torque acquired by the motor torque acquisition unit, the angular acceleration acquired by the angular acceleration acquisition unit, the contact force acquired by the contact force acquisition unit, and a coefficient of friction between the wheel of the vehicle and a contact surface.

摘要： Embodiments disclosed herein relate to a thin, light, and portable system for measuring one or more parameters of a contact patch between a tire and a surface. The system may be configured with an array of sensors capable of being removable fixed to the surface. The array of sensors may measure the one or more parameters of the contact patch between the tire and the surface. Moreover, the system may include a scanner configured to interpret the measurements from the array of sensors as data and store the data.
