PROBLEM TO BE SOLVED: To avoid that a driver feels a sense of incompatibility due to the unexpected restarting of an engine.SOLUTION: A stop-engine request that is output in response to the operation of a brake by a driver, and a stop-engine prohibition request that is output due to the diagnosis of a malfunction in an air-fuel ratio sensor provided in the engine exhaust system or the like, are independent requests, and when both requests are output simultaneously, the stop-engine request, which has higher priority, is executed. When the engine is thus stopped by means of a higher-priority stop-engine request, the stop-engine prohibition request is dismissed so as to prevent the unexpected restarting of the engine when the stop-engine request is canceled. |
