Abstract: In the case where drive power of a vehicle is increased, a control device starts micro-braking control for generating a braking force on at least one wheel of a front wheel and a rear wheel. During execution of the micro-braking control, the control device estimates an efficacy factor that is a factor indicating a relationship of a magnitude of the braking force to a magnitude of a pressing force generated by a friction braking system. The control device estimates the efficacy factor for the wheel, to which the braking force is applied by the micro-braking control, on the basis of a deviation between generated drive power, which is based on a required value for a power source, and actual drive power actually acting on the vehicle, and the pressing force corresponding to the wheel, to which the braking force is applied by the micro-braking control.
