Abstract
A drive control device includes: a meshing engagement unit; an engine; a rotary machine; a detector detecting a predetermined parameter; and a controller configured to perform a release control of causing the rotary machine to output a second rotation torque in a direction opposite to a first rotation torque applied from the engine to the engagement unit at a time the engagement unit is released. The release control includes setting a magnitude of the second rotation torque to a predetermined value larger than a magnitude of the first rotation torque at a time the predetermined parameter change degree is not smaller than a threshold value and gradually decreasing the magnitude of the second rotation torque, and setting the magnitude of the second rotation torque to a magnitude smaller than the predetermined value at a time the predetermined parameter change degree is smaller than the threshold value.
