The method makes possible a more precise application of coefficients of friction and comprises the following steps: - providing a coefficient of friction (渭) for a road surface section (160, 170) by means of a database (120), to which database the at least one first vehicle (140) and ...

David Bryant, Andrew Day, in Braking of Road Vehicles (Second Edition), 2022 3.3.2 Adhesion coefficient Tyre/road grip is generally specified in terms of an ‘adhesion coefficient’ which is the maximum or limiting value of the ratio of the tangential force generated by a road wheel that is...
Many surveys on vehicle traffic safety have shown that the tire road friction coefficient (TRFC) is correlated with the probability of an accident. The probability of road accidents increases sharply on slippery road surfaces. Therefore, accurate knowled

On the one hand, due to the viscosity of the fluid, frictional forces act on theskin of the body, resulting in a so-calledskin friction drag. The decisive factor here is the shear stress acting on the surface of the body. These shear stresses are also known aswall shear stressesτw. ...
Friction coefficient means the ratio between the tangential force and the normal force acting between the brake pad and the disc or the brake shoe and the drum. For a disc brake, the apparent friction coefficient value from the brake under testing is a function of braking torque, effective bra...
The device prevents irritating effects on the user's body caused by the diagonal seat belt strap in a motor vehicle. It reduces abrasion of the user's clothing caused by frequent changes of body position. The relevant length of the diagonal strap is enclosed in a sheath which, once in posi...
The real-time road surface friction coefficient (RSFC) is a critical parameter for evaluating skid resistance and making safe driving decisions in driver assistance systems and autonomous vehicles, especially under adverse weather conditions. RSFC estimation depends on the interaction between the road surf...
Due to their influence on the fuel consumption of vehicles, tyres are officially categorized in energy efficiency classes (see Table 3.1) based on their measured rolling resistance. The European Regulation [110] lays down a scale of classes based on the rolling resistance coefficient (RRC). The ...
