Summary:The disclosure of Japanese Patent Application No. 2000-121571 filed on Apr. 21, 2000 including the specification, drawings and abstract is incorporated herein by reference in its entirety. An internal combustion engine control unit for hybrid vehicle makes an electric motor function as a main driving source for the vehicle under a predetermined condition and at the same time, controls a hybrid mechanism so as to warm up the internal combustion engine. If a requested engine output to the internal combustion engine exceeds a predetermined output or if an accelerator opening degree exceeds a predetermined opening degree, the same control unit changes the operating condition of the internal combustion engine from the warm-up operation condition to an operation condition fitting to the requested engine output.
