A method of thermal management of an internal combustion engine of a hybrid propulsion system comprising an internal combustion engine and an electric motor-generator connected to a transmission, the method, in cold-start conditions of the internal combustion engine, comprises at least the following steps: acquiring and modifying a nominal torque curve (NT) of the internal combustion engine to obtain a limited torque curve (LT), distinct from said nominal torque curve (NT); controlling said electric motor-generator so as to provide a resistant torque, to said internal combustion engine, complementary to a required torque (UT), so that a total torque value supplied by the internal combustion engine belongs to said limited torque curve (LT).
