ABSTRACT:
A braking/driving force fx is calculated at S102, and a lateral force Fy is calculated at S103. At S104, reference is made to a preset map to select a road surface μ estimation part to be used for determination (to select a first road surface μ estimation part25or a second road surface μ estimation part26or nonperformance of determination. At S105, a display flag Fla from the road surface μ selection part is read. Indication1is displayed (S107) in the case of a road having a high μ. Indication2is displayed (S109) in the case of a road having a medium μ. Indication3is displayed (S111) in the case of a road having a low μ. Indication0is displayed (S112) in other cases wherein the road surface μ is unknown.
