Abstract
A power transmission controlling apparatus of a vehicle includes a clutch capable of connecting/disconnecting power transmission between an engine and a motor/generator, and a torque converter enabling power transmission between the engine or/and the motor/generator and an automatic transmission. When the engine is started by motoring torque with engagement of the clutch during rotation of the motor/generator, the power transmission controlling apparatus sets a torque compensation amount by the motor/generator based on an estimated torque capacity of the clutch, and suppresses torque fluctuations on a power transmission path accompanying engagement of the clutch by power of the motor/generator containing the torque compensation amount. The power transmission controlling apparatus corrects the torque capacity or the torque compensation amount based on input torque of the torque converter.
