Abstract
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.
