Abstract
A work vehicle includes an engine, a hydrostatic transmission, a work implement pump driven by the engine, a work implement driven by hydraulic fluid discharged from the work implement pump, an accelerator, a first sensor configured to output a signal indicative of an operation amount of the accelerator, a work implement operating member, a second sensor configured to output a signal indicative of an operation amount of the work implement operating member, and a controller. The controller is configured to receive signals from the first sensor and the second sensor, determine a target input horsepower input to the hydrostatic transmission from the operation amount of the accelerator, and determine a target rotational speed of the engine from the target input horsepower and the operation amount of the work implement operating member.
