The third estimator estimates a road surface friction coefficient from the first road surface friction coefficient and the second road surface friction coefficient on a basis of a first reliability degree and a second reliability degree, the first reliability degree indicating a reliability of the first road surface friction coefficient, the second reliability degree indicating a reliability of the second road surface friction coefficient."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Road surface friction coefficient estimation apparatus for vehicle and road surface friction coefficient estimation method for vehicle","description":"A road surface friction coefficient estimation apparatus for a vehicle includes: a first estimator; a second estimator; and a third estimator.
