20100145560 | HYBRID VEHICLE AND METHOD FOR CONTROLLING HYBRID VEHICLE - An EV priority switch is configured to allow a user to request a change between an EV priority mode and an HV mode. If an SOC of a power storage device is less than a first threshold value when the change to the HV mode is requested from the EV priority switch during the EV priority mode, an ECU changes the running mode to attain the HV mode and controls the SOC to be close to the SOC at the moment of a request for the change to the HV mode. If the SOC is greater than or equal to the first threshold value, the ECU maintains the EV priority mode. If the SOC reaches a second threshold value less than the first threshold value, the ECU forcefully changes the running mode to attain the HV mode. | 06-10-2010 |
