Abstract:
An ENG-ECU performs a specific cylinder fuel cutoff process of stopping combustion of an air-fuel mixture in some cylinders out of a plurality of cylinders of an internal combustion engine and a transmission process of transmitting engine operation information on execution of the specific cylinder fuel cutoff process to an HV-ECU. The HV-ECU performs a torque compensation process of compensating for a decrease in engine torque due to execution of the specific cylinder fuel cutoff process using an output torque of a second MG based on the received engine operation information. The ENG-ECU performs a process of starting the specific cylinder fuel cutoff process in a combustion cycle when a waiting time which includes a time until the HV-ECU receives the engine operation information has elapsed after the transmission process has been performed.
