HYBRID-VEHICULAR ENGINE START CONTROL APPARATUS

摘要

PROBLEM TO BE SOLVED: To start the engine of a hybrid vehicle with power consumption suppressed and without causing a feeling of lagging.SOLUTION: An engine start control apparatus performs: setting a predetermined target transmission torque capacity as a transmission torque capacity of a clutch and controlling torque of a first motor-generator so that an input rotation speed of a power division mechanism matches a predetermined target rotation speed; controlling the torque of the motor so that torque of the motor exerted to a clutch equals to torque equivalent to the target transmission torque capacity when an input rotation speed reaches the target rotation speed; and correcting output torque of the motor using correction toque calculated on the basis of inertia moment of the motor and a gear ratio of the power division mechanism in the case where the input rotation speed is deviated from the target rotation speed by a predetermined given value or more (step S4).
