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.

1. An internal combustion engine control unit for a hybrid vehicle, comprising: a hybrid mechanism that drives the vehicle by selectively using power of the internal combustion engine and power of an electric motor; and a controller that drives the vehicle with the power of said electric motor as a main driving power and controls said hybrid mechanism so as to warm up said internal combustion engine, said controller inhibits warm-up operation of said internal combustion engine if at least one of conditions: (a) a requested engine output to said internal combustion engine is more than a predetermined output, and (b) an accelerator opening degree is equal or more than a predetermined opening degree, is satisfied when said internal combustion engine is being warmed up. 2. The internal combustion engine control unit according to claim 1, wherein the controller changes an operating condition of the internal combustion engine from a warm-up operation condition to another operation condition if at least one of the conditions is satisfied. 3. The internal combustion engine control unit according to claim 2, wherein the another operation condition is a condition for outputting a power depending on the requested engine output. 4. The internal combustion engine control unit according to claim 2, wherein the controller estimates a time for changing the operation condition from the warm-up operation condition to a predetermined operation condition; and changes the operation condition of the internal combustion engine gradually from the warm-up operation condition to the predetermined operation condition prior to the estimated changing time. 5. The internal combustion engine control unit according to claim 1, wherein the predetermined output is a maximum output generated by the internal combustion engine in the warm-up operation condition. 6. A method of controlling an internal combustion engine unit of a hybrid vehicle, the hybrid vehicle having a hybrid mechanism that drives the hybrid vehicle by selectively using power of the internal combustion engine and power of an electric motor, the method comprising: inhibiting warm-up operation of the internal combustion engine if at least one of conditions: (a) a requested engine output to said internal combustion engine is more than a predetermined output, and (b) an accelerator opening degree is equal or more than a predetermined opening degree, is satisfied when said internal combustion engine is being warmed up. 7. The method of controlling an internal combustion engine of claim 6, further comprising changing an operating condition of the internal combustion engine from a warm-up operation condition to another operation condition if at least one of the conditions is satisfied. 8. The method of controlling an internal combustion engine of claim 7, wherein the another operation condition is a condition for outputting a power depending on the requested engine output. 9. The method of controlling an internal combustion engine of claim 7, further comprising: estimating a time for changing the operation condition from the warm-up operation condition to a predetermined operation condition; and changing the operation condition of the internal combustion engine gradually from the warm-up operation condition to the predetermined operation condition prior to the estimated changing time. 10. The method of controlling an internal combustion engine of claim 6, wherein the predetermined output is a maximum output generated by the internal combustion engine in the warm-up operation condition.
