Provided are a work vehicle capable of reproducing the same operation feeling as that of a torque converter-type work vehicle, and a work vehicle control method. A control unit includes a work implement requirement determination unit, a transmission requirement determination unit, and a distribution ratio determination unit. The work implement requirement determination unit determines a work implement required power on the basis of an operation amount of a work implement operating member and the work implement pump pressure. The transmission requirement determination unit determines a transmission required power on the basis of the vehicle speed and the operation amount of the accelerator operating member. When the sum of the work implement required power and the transmission required power is greater than a first distributable power that a predetermined preferential distribution power subtracted from a load upper limit power of the engine leaves, the distribution ratio determination unit allocates the smaller of a transmission compensation power and the transmission required power to a power transmission device and distributes the remainder of the first distributable power to the work implement pump and to a power voltage device.
