Patent ID: 8870710

Claim:
A vehicle drive control system comprising: a motor, coupled with a driving shaft of an internal combustion engine mounted in a vehicle; wherein: torque from the engine can be transmitted to one or more drive wheels of the vehicle when fuel supply to the engine is cut off; the vehicle is made to travel in a creeping manner while motoring of the engine is performed through driving force of the motor; when both a braking operation and an accelerating operation are not occurring, the vehicle is made to travel in the creeping manner while motoring of the engine is performed through driving force of the motor; when a rotation speed of the engine is the same as or lower than a first predetermined rotation speed, the motor is controlled such that a preliminary set initial value of driving torque is outputted such that the rotation speed of the engine reaches the first predetermined rotation speed; a target rotation speed of the engine is set to a preliminary set second predetermined rotation speed after the engine reaches the first predetermined rotation speed; the rotation speed of engine changes from the preliminary set second predetermined rotation speed, at a first predetermined changing speed, to an idle target rotation speed of the engine after the engine reaches the first predetermined rotation speed; driving torque of the motor is calculated through a rotation speed feedback control calculation based on a difference between the set target rotation speed and the rotation speed of the engine; and the motor is controlled to output the calculated driving torque.
