PROBLEM TO BE SOLVED: To provide a tire force control device capable of reducing fluctuation in brake pressure during and ABS operation in a saddle-riding type vehicle inclined to turn.SOLUTION: A tire force control device 50 that controls the tire force of a saddle-riding type vehicle inclined to turn has: a tire force estimation unit 51 that estimates the longitudinal force of each wheel and the vertical dynamic load of each wheel; a friction coefficient calculation unit 52 that calculates the friction coefficient of a road surface with respect to each wheel on the basis of the longitudinal force and the vertical dynamic load of each wheel; a discretization processing unit 53 that calculates a discretized friction coefficient by discretizing the friction coefficient; a target longitudinal force calculation unit 54 that calculates the target longitudinal force of each wheel on the basis of the discretized friction coefficient and the vertical dynamic load of each wheel; a target torque calculation unit 56 that calculates the target torque of each wheel by adding together the target longitudinal force of each wheel and an ideal wheel inertial value corresponding to the discretized friction coefficient stored in a data storage unit 55; and a slip determination unit 57 that determines slipping of each wheel on the basis of the target torque of each wheel.SELECTED DRAWING: Figure 2
