Vehicle driving system control apparatus

A vehicle driving system control apparatus comprising

• a power transmission device capable of transmitting a power of an engine, a power of a first motor generator, and a power of a second motor generator to an axle of a vehicle, and
• a power transmission control section,
• wherein the power transmission device includes:
• an engine input shaft transmitting the power of the engine;
• a motor input shaft transmitting the power of the first motor generator;
• an output shaft receiving the power of the second motor generator and outputting the power to be transmitted to the axle;
• an engine-side gear mechanism transmitting the power of the engine input shaft to the output shaft without the motor input shaft;
• a motor-side gear mechanism transmitting the power of the motor input shaft to the output shaft without the engine input shaft;
• a first clutch being engaged and disengaged so as to enable and disable a power transmission between the engine input shaft and the motor input shaft;
• a second clutch being engaged and disengaged so as to enable and disable a power transmission between the motor-side gear mechanism and the output shaft;
• and
• a third clutch being engaged and disengaged so as to enable and disable a power transmission between the engine-side gear mechanism and the output shaft, and
• wherein the power transmission control section determines engagement and disengagement statuses of the first to third clutches and required torques of the first and second motor generators in correspondence with a rotation speed of the axle.
