ABSTRACT:
A control system and method for accelerating the warm-up operation of a hybrid vehicle while preferably using the characteristics of the hybrid vehicle. The system comprises a warm-up accelerating section for accelerating warm-up of the engine by controlling the ignition timing of the engine according to a temperature of water for cooling the engine; and a power generation control section for performing power generation using the motor according to a remaining charge of a battery of the vehicle. The warm-up accelerating section has an ignition timing correcting section for correcting the ignition timing according to an amount of generated power which is controlled by the power generation control section. Therefore, in comparison with the case of performing the warm-up operation by simply using both the ignition timing retardation and the power generation, the ignition timing can be close to the optimum point, thereby improving the combustion efficiency.
