A control device for a compression ratio variable internal combustion engine is provided with a compression ratio variable mechanism capable of changing an engine compression ratio in accordance with a rotation position of a control shaft and a compression ratio detection unit that detects an actual compression ratio. In a predetermined engine operation state (S11), for example, immediately after an engine start, a reference position learning operation for the compression ratio detection unit is carried out with the control shaft mechanically locked on a predetermined reference position (S12). During an engine operation, if the actual compression ratio is lost due to a communication error or the like (S13), or if a difference between the actual compression ratio and a target compression ratio is larger than expected due to some abnormalities (S14), the reference position learning operation is immediately carried out (S15), thereby causing a quick return to the state in which normal compression ratio control can be performed.
