Abstract
A control device for restarting an engine of vehicle wherein determination is made on whether a quick pressure increase control is executable. When the quick pressure increase control is determined to be non-executable, the engine torque is reduced as compared to a case where the quick pressure increase control is executable. Further, the engine torque is set at a value when the engine speed is equivalent to an idle speed. Also, when the engine torque is reduced, the brake pressure hold electromagnetic valve is maintained at a hold state. This reduces an engagement shock upon engagement of the clutch and prevents the deterioration of clutch durability, in the case where the quick pressure increase control immediately after restart of the engine is non-executable.
