A controller includes a neutral control determination unit, a forward-reverse clutch control unit, and a commanded torque setting unit. The neutral control determination unit executes quasi-neutral control when a quasi-neutral control determination condition is satisfied. The quasi-neutral control determination condition includes cases where the forward-reverse operation member is in the neutral position. The forward-reverse clutch control unit keeps the forward-travel clutch or the reverse-travel clutch engaged during the quasi-neutral control. During quasi-neutral control, the commanded torque setting unit determines a commanded torque sent to the motor so that a neutral state is set where the output torque from the power transmission device to the travel device is kept at a prescribed value regardless of the drive power output from the engine.
