<P>PROBLEM TO BE SOLVED: To provide a driving control device of a hybrid car for both securing highly efficient motor travel and maintaining exhaust emission control performance of combustion gas in an engine co-rotating motor travel scene with a driving motor as a motive power source. <P>SOLUTION: This driving control device of the hybrid car is driven by an engine 1 or the driving motor 3 or simultaneous use of the engine 1 and the driving motor 3, and is provided with a motor driving continuation permitting time setting step S121 for setting motor driving continuation permitting time so that a catalyst temperature reduced by engine co-rotation does not become less than a lower limit catalyst temperature A in the engine co-rotating motor travel with the driving motor 3 as the motive power source, when defining a lower limit catalyst temperature for maintaining an exhaust emission control rate by a catalytic converter 16 arranged downstream of the engine 1 as the lower limit catalyst temperature A. <P>COPYRIGHT: (C)2004,JPO |
