Abstract:
1. An engine system control device to be applied to an engine system provided with an engine having a variable compression ratio mechanism capable of changing a compression ratio, comprising: a compression ratio acquiring unit configured to acquire a setting state of the compression ratio by the variable compression ratio mechanism; a compression ratio control system failure detecting unit configured to detect generation of failure in a compression ratio control system including the variable compression ratio mechanism and the compression ratio acquiring unit; an intake and exhaust system determining unit configured to determine a state of a member placed in an intake and exhaust system of the engine; and an intake and exhaust system determination permitting unit configured to permit determination by the intake and exhaust system determining unit, wherein the intake and exhaust system determination permitting unit is configured to inhibit the determination by the intake and exhaust system determining unit, in the case where the compression ratio control system failure detecting unit detects the generation of the failure.
