PROBLEM TO BE SOLVED: To enable automatic and simple determination of power distribution between an engine assist and a work apparatus so as to acquire excellent overall vehicle fuel economy.SOLUTION: A work vehicle performs: an initial setup of an engine assist battery power limiter "a" that is a lowest limit of SOC produced by dividing a battery residual capacity by a full-charge capacity in order to determine whether to perform a travel assist to support a travel by supplying a travelling motor with battery power; an initial setup of a power shortage occurrence counter variable "b" that is a lowest limit of SOC at the time of driving a work apparatus; counting a power shortage occurrence counter variable "c" that is the number of times of events where the SOC is smaller than the variable "b" at the time of driving the work apparatus; and increasing the limiter "a" every time the counted variable "c" exceeds a given number of times, transitioning to a motorized actuator-prioritized. |
