DEVICE AND METHOD FOR ESTIMATING FRICTION OF EARTH SURFACE IN CONTACT WITH TRANSPORT FACILITY Russian patent published in 2012 - IPC B60W40/06 B60L7/18 B60T8/172 B60T8/1755 

Abstract RU 2468945 C1

FIELD: transport.

SUBSTANCE: set of inventions relates to estimation of friction on the surface of contact between vehicle wheel and soil or adhesion between wheels and road surface. Envisaged are module (or step) of first input, module (or step) of second input and module (or step) of output. Module of first input sets first input that represents ratio between first force acting on wheel on soil contact surface in first direction and first degree of wheel skid. Module of second input sets second input that represents ratio between second force acting on wheel on soil contact surface in second direction and second degree of wheel skid. Module of output derives output from first and second inputs that makes parameter describing adhesion of transport facility wheel.

EFFECT: high accuracy of estimation.
