1. System for checking a combustion engine (1) coupled with an electric generator (2) of a hybrid terrestrial vehicle having at least a drive line (61, 62) driven by at least one electric motor (51, 52), said combustion engine (1) comprising at least one subsystem to be checked, said system comprising first control means (3) configured to drive the combustion engine (1) at just one or at a few discrete predefined deterministic operation points according to a normal condition of said combustion engine,said system being characterized in that it comprises second control means able to perform at least a diagnostic test on said at least one subsystem and in that said first control means (3) are configured to disregard said predefined deterministic operation points according to a diagnostic condition of said combustion engine and to vary the operation conditions of said combustion engine (1) in order to allow said second control means to perform said diagnostic test.
