Controller of hybrid system

摘要

In a controller of a hybrid system including an engine, a motor/generator, an automatic clutch to which engine torque is input, a gear group configured to transmit input torque to a driving wheel side, and a differential device provided with plural rotary elements to which a torque input side of the gear group, a rotating shaft of the motor/generator, and an output side of the automatic clutch are individually connected respectively, wherein at the time a vehicle is started by causing the motor/generator to be in charge of a reaction force of the engine torque and transmitting the engine torque to the driving wheels via the differential device and the gear group, the automatic clutch is slip controlled in a semi-engaged state.
