摘要： Resilient members having near-surface architectures including microstructures for controlling friction are provided. A film-terminated array of fibrils having a sharp film/fibril juncture exhibits an unexpectedly large enhancement of adhesion, static friction and sliding friction. The enhancement is provided against rough indenters. A film-terminated array of elongated ridges and valleys unexpectedly exhibits low adhesion, and an unexpectedly large enhancement of sliding friction. The film-terminated ridge/valley design provides an anisotropic structure with direction-dependent frictional properties. The increase in sliding friction force varies as a function of interfibrillar spacing, and corresponds to a mode in which buckling of the terminal film occurs. The near surface architectures may be designed with varying scales and varying parameters to provide performance characteristics tailored to various applications. By way of example, the film-terminated ridge/valley array may be incorporated in motor vehicles tires to provide low rolling resistance and high sliding friction allow for high-performance braking during vehicle operation.

摘要： The invention relates to a method for determining a limit speed for driving for a driver at the steering wheel of a vehicle, the method involving the following steps during which: - the potential grip available at a given moment between a tyre of the vehicle and the road surface on which the tyre is driving is estimated as a function of known and/or measured influencing parameters, - a need for grip is determined as a function of the vehicle driving situation and driving characteristics of the driver of the vehicle, - a limit speed for driving that ensures that the potential grip available is not exceeded is determined as a function of this need for grip and of the estimated potential grip.
