Abstract
A control device of a work vehicle includes a required output torque determination unit that determines a required output torque of the power transmission device based on an operation amount of the operation device and a traveling speed of the work vehicle, a traveling load estimation unit that estimates a traveling load torque related to a traveling load on the work vehicle, a required output torque correction unit that corrects the required output torque such that the required output torque is included in an allowable output torque range including an estimated traveling load torque, and a drive source control unit that outputs a control signal for the drive source based on a corrected required output torque.
