HYBRID CAR, METHOD FOR CONTROLLING HYBRID CAR, AND COMPUTER-READABLE RECORDING MEDIUM WITH PROGRAM FOR MAKING COMPUTER EXECUTE CONTROL METHOD OF HYBRID CAR RECORDED THEREIN

摘要

PPROBLEM TO BE SOLVED: To provide a hybrid car for surely securing a vehicle driving force when a vehicle slides down on a hill-climbing road. PSOLUTION: When a road gradient during traveling is larger than a threshold, an HV-ECU starts an engine when the engine is stopped (S50). Then, when determined that the vehicle slides down (S60: YES), the HV-ECU changes the operating point of the engine, and increases engine transmission torque to be output from the engine to a driving shaft (S70). Furthermore, the EV-ECU decides the operating points of the motor generators MG1 and MG2 so that regenerative torque of the motor generator MG2 can be reduced (S80). PCOPYRIGHT: (C)2008,JPO&INPIT
