ABSTRACT:
A drive control apparatus for a vehicle including an engine which generates power using combustion of fuel; a hydrodynamic power transmission device which transmits an output of the engine via fluid, includes an input side and an output side which can be directly coupled; a lock-up engagement device which engages the lock-up clutch when a predetermined lock-up engagement condition is satisfied; and a lock-up restriction device which stops engagement control performed by the lock-up engagement device so as to disengage the lock-up clutch if there is a possibility that knocking will occur in the engine when the lock-up clutch is engaged by the lock-up engagement device. A shock at the time of tip-in acceleration is suppressed irrespective of knocking prevention control so as to improve riding comfort. In addition, occurrence of a droning noise is suppressed.
