Abstract
A work implement requirement determination unit of a work vehicle determines a work implement required power based on the operation amount of a work implement operating member and the work implement pump pressure. A transmission requirement determination unit determines a transmission required power based on 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, a 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 transmission device.
