Hybrid work machine
A hybrid work machine includes a controller and a temperature sensor that detects an electric storage device temperature. In a case where (Tp+Tc)≥Te_min, the controller carries out a first comparison in which the controller compares a value of [(Tp+Tc)−Te_min] with a value of Ta_SOC, and the controller then selects a lower value of the first comparison. The controller then carries out a second comparison in which the controller compares the selected lower value of the first comparison with a value of [(Tp+Tc)−Te_max)]. The controller then sets a higher value of the second comparison as the torque of the assist motor Ta, wherein Tc is an accessory torque, Ta_SOC is an adjustment assist motor torque based on a current state of charge of the electric storage device, Ta is the torque of the assist motor, and Te_max is an engine maximum torque.
