INTERNAL COMBUSTION ENGINE STARTING/STOPPING CONTROL DEVICE FOR HYBRID VEHICLE

Japanese Patent JP3763474

B2

PROBLEM TO BE SOLVED: To provide an internal combustion engine starting/stopping control device for a hybrid vehicle capable of preventing blowing up of the internal combustion engine in starting, and preventing uncomfortable vibration caused by resonance in controlling stopping without upsizing the device, lowering reliability and increasing its cost. SOLUTION: This internal combustion engine starting/stopping control device for the hybrid vehicle, including an inner combustion engine and a motor-generator and capable of controlling an operating state of the internal combustion engine with the motor-generator, comprises a rotational speed detecting means for detecting rotational speed of the motor-generator after a stopping instruction to the internal combustion engine, and a control means for controlling the motor-generator to suppress the operation of the internal combustion engine on the basis of the rotational speed detected by the rotational speed detecting means.
