Tire-road friction coefficient (TRFC) is of critical importance for advanced vehicle control systems and autonomous vehicle applications. This paper presents a sequential tire longitudinal stiffness and TRFC estimation method for road vehicles by separate control of the front and rear wheels, for which...
The main function of antilock braking systems is to prevent the wheel lock during heavy braking and to maintain the traction between the tires and the road at an optimal value. The magnitude of this optimal traction is usually determined based on the tire road friction coefficient (TRFC). The...

The coefficient of friction depends on the materials used. As an example,ice on steel has a lowcoefficient of friction – the two materials slide past each other easily – while rubber on pavement has a high coefficient of friction – the materials do not slide past each other easily. ...

aThe coefficient of friction — This factor relates the amount of friction force between two surfaces to the force holding the two surfaces together. In our case, it relates the amount of traction between the tires and the road to the weight resting on each tire. 正在翻译,请等待...[translat...
The TRPFC can be used to characterize the skid resistance between the tires and the road surface, which is the basis for the proper operation of active vehicle safety technologies and an indispensable evaluation index for road maintenance [4]. Therefore, the study of the estimation of the ...
Since there is no significant difference in the longitudinal stiffness of the tires on the rigid pavement with low and high friction in the low longitudinal excitation condition, the longitudinal stiffness of the tires generally requires large excitation to obtain accurate identification results [11,19...
ice on steel has a low coefficient of friction, while rubber on pavement (i.e. car tires on the road) has a comparatively high one. In short, rougher surfaces tend to have higher effective values whereas smoother surfaces have lower due to the friction they generate when pressed together. ...
