Title:
ROAD SURFACE FRICTION COEFFICIENT ESTIMATION DEVICE AND STEERING DEVICE
Document Type and Number:
Japanese Patent JP2021165055
Kind Code:
A
Abstract:
To provide a road surface friction coefficient estimation device and the like which can estimate a friction coefficient of a road surface adequately even at normal travel time when time response lag is small and tire generation force is small.SOLUTION: A road surface friction coefficient estimation device is configured so as to comprise a wheel acting force sensor 200 which detects acting force to wheels, a moment calculation part which calculates a moment MtZ around a vertical axis in a grounding load center of a tire on the basis of output of the wheel acting force sensor, and a friction coefficient estimation part 300 which estimates a friction coefficient of the road surface where the tire is grounded on the basis of the moment.SELECTED DRAWING: Figure 8
