In a hybrid vehicle with an internal combustion engine and a motor mounted thereon, operation of the internal combustion engine stops when a battery has a large remaining charge, so that inspection of the internal combustion engine can not be carried out under such conditions. The present invention controls the internal combustion engine to drive in an inspection mode that is different from a normal driving state at the time of inspection of the internal combustion engine. A control unit mounted to control operation of the internal combustion engine and the motor carries out an inspection control routine in the following manner. The inspection of the internal combustion engine is carried out while a terminal T of a diagnosis connector is connected with a terminal E. The control procedure thus keeps the internal combustion engine driving irrespective of the remaining charge of the battery while the terminals T and E are connected with each other. Inspection of exhaust is carried out, while the connection of the terminal T with the terminal E is released. The control procedure accordingly keeps the internal combustion engine driving irrespective of the remaining charge of the battery until a predetermined time period has elapsed since the release of the connection. The structure of the present invention prevents the operation of the internal combustion engine from being stopped at the time of inspection and enable the inspection of the internal combustion engine.

[ What is claimed is:] [1.] An apparatus for controlling operation of an internal combustion engine in a hybrid vehicle with said internal combustion engine and a motor mounted thereon, said apparatus comprising:an operation stop unit which stops operation of said internal combustion engine when an essential condition characteristic of said hybrid vehicle is satisfied among conditions for stopping the operation of said internal combustion engine;a detection unit which determines an inspection of the operation of said internal combustion engine is in progress; anda continuous operation control unit which controls the operation of said internal combustion engine when said detection unit determines that the inspection of the operation of said internal combustion engine is in progress, and thereby keeps a predetermined driving state suitable for the inspection of the operation of said internal combustion engine even when the essential condition characteristic of said hybrid vehicle is satisfied among the conditions for stopping the operation of said internal combustion engine.
