CONTROL DEVICE AND CONTROL METHOD OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a control device and a control method of an internal combustion engine that can protect an electric motor while restraining a sudden change in torque.SOLUTION: A control device 210 and a control method of an internal combustion engine 100 comprise a variable compression ratio mechanism 190 that changes a compression ratio by an electric actuator 198, and prohibit the control of the compression ratio to the high compression ratio side when an abnormality occurs in the variable compression ratio mechanism 190.
