装置。[Scope of claim for utility model registration] A compression ratio map that defines a low compression ratio region and a high compression ratio region with respect to engine speed and engine load, and individual engine operating conditions other than engine speed and engine load. and a compression ratio correction map for each operating condition that provides a correction value for correcting the boundary between the low compression ratio region and the high compression ratio region in the compression ratio map in the form of engine load; operating conditions are sent to the compression ratio map, operating conditions other than engine speed and engine load are sent to the compression ratio correction map to output a compression ratio correction value, and this output is sent to the compression ratio map to determine the compression ratio area. The compression ratio map, the compression ratio correction map, and the input signals from each operating condition sensor are correlated so that the compression ratio is determined by the compression ratio map whose boundaries have been finely adjusted. A control device for a variable compression ratio mechanism.
