    Abstract: A method of developing a set of input forces used to analyze tire wear includes the steps of characterizing a wear course by driving a vehicle over the wear course and measuring data related to a plurality of forces experienced by the vehicle. A vehicle characterization model for a target vehicle having at least one tire is developed. The vehicle characterization model is used to calculate force data that represents the forces that would be experienced by at least one tire of the characterized vehicle if the characterized vehicle were driven over the characterized wear test course in the first vehicle configuration. The force data is then used to analyze tire wear using a computer prediction technique or by running an indoor wear test on the tire.

    Abstract: This is a multi-functional warning system for a vehicle and the related control method. This system is composed of a host unit and branch units. The branch unit is deposed in a tire, which includes sensor(s) for monitoring the pressure, temperature or other information about the tire; if it detected a tire in deflated, high temperature or loosed status, it would generate a RF signal that would be sent to the host unit. The host unit deals with not only aforesaid RF signals, but also signals from acceleration sensor and signals about high-water-temp., low-oil­ pressure etc., a CPU processes all information and then gives a corresponding indication in voice, digital and light to warn the driver. Upon severe tire failure or high deceleration of the vehicle, the host unit send out a warning signal, make a warning light flicker to provide the follow-on vehicle with a warning, in bad weather it can turn on the warning light to guide and prevent rear-end collision. The system has advantage of giving an intelligent warning for tires, devices in the vehicle, and the trouble like high deceleration, which secure the safety of the personnel and the vehicle.

    Abstract: Method and apparatus for conducting indoor hydroplaning tests on a tire. A tire is supported by a frame above a test surface and a load is applied to the tire tread against the test surface. A stream of high pressure fluid is discharged from a nozzle against an area of contact of the tire tread and the test surface. A device detects a change in the loaded contact of the tire as the pressure of the fluid stream increases which provides an indication that hydroplaning is beginning to occur in comparison with a previously tested tire under actual driving conditions.
