1. A control device for a work vehicle that includes an engine, an accelerator, a work equipment operation device, an inching operation device, and a shift operation device,
the control device being configured to control an engine output of the engine based on an accelerator operation amount of the accelerator and a work equipment operation amount of the work equipment operation device, the control device comprising:
an accelerator operation amount correction unit that obtains a corrected accelerator operation amount by correcting the accelerator operation amount based on an inching operation amount of the inching operation device;
a target vehicle speed determination unit that determines a target vehicle speed based on
the corrected accelerator operation amount and
a signal based on an operation of the shift operation device;
a deceleration correction unit that obtains a corrected target vehicle speed by correcting the target vehicle speed based on the inching operation amount; and
an engine control unit that outputs a control command to a fuel injection device of the engine based on the corrected accelerator operation amount and the corrected target vehicle speed.
