Abstract: A method for measuring deformation of a tire tread is provided. The method uses a tire tread deformation producing system 10 including a flat, transparent base plate 24 having first and second opposite surfaces 24a and 24b. The method also uses a vision system 12 including a pair of CCD cameras 30-1 and 30-2, which are positioned on the side of the second surface of the base plate. A test tire 14 has a tire tread having tread grooves 16. A portion of the tire tread of the test tire is urged against the first surface of the base plate. The three-dimensional shape of a groove wall surface of a tread groove of the test tire is measured by imaging the tread groove across the base plate by the CCD cameras while the test tire is subject to deformation.

Abstract: Tire transient response data during cornering with a slip angle is calculated based on a tire dynamic model. A deformation response of a tread part in the tire dynamic is set as a first-order-lag response. The value of the transient response parameter is initialized, to define the first-order-lag response. The time-series data of the transient response of the slip angle between the tread part and a road surface in the tire dynamic model is obtained by computing a convolution integral of the defined response function of the first-order-lag response with a time gradient of the time-series data of the slip angle. A value of a lateral force is calculated by using the tire dynamic model based on the obtained time-series data of the transient response of the slip angle. Accordingly, the transient response data is calculated, and a value of the transient response parameter is obtained.

Abstract: A tire characteristic judging device judges a tire characteristic in the following way. At first, a load applied to a tire and a cornering force generated in the tire in time series while the tire is rolling are acquired. Then, an applied load variation amount is calculated from the acquired time-series applied load information and a cornering force variation amount calculated from the acquired time-series cornering force information. Next, an evaluation value is calculated based on the applied load variation amount and the cornering force variation amount. The calculated evaluation value and a preset reference value are compared with each other and whether or not the tire satisfies a desired characteristic is judged according to a result of comparison.
