A traction controller for an electric vehicle according to the present disclosure calculates a first target torque and a second target torque. The first target torque is a motor torque for achieving a target rotational speed calculated based on a target slip. The second target torque is a motor torque for achieving a target driving force set based on an estimated friction coefficient of a road surface and a ground contact load. The traction controller determines an arbitration target torque with the first target torque as a required value and the second target torque as a constraint condition, and controls the motor based on the arbitration target torque.
