Abstract
A drive control device for a vehicle is configured: to determine whether or not a sound pressure level inside a vehicle cabin becomes a predetermined value or less, under a state where it is predicted that a meshing-type engagement mechanism is changed from a disengaged state to an engaged state; and to prohibit the meshing-type engagement mechanism from entering the disengaged state, when it is determined that the sound pressure level becomes the predetermined value or less. In the disengaged state, transmission of a power output from a driving force source to driving wheels as drive energy is interrupted.
