POWER SUPPLY CONTROL APPARATUS AND METHOD FOR HYBRID VEHICLE |
摘要 |
When the temperature of an engine and a main battery is low at the time of activating a vehicle system, an ECU starts the engine in advance and outputs a running permission signal after completion of engine startup. At this stage, the ECU suspends a defect diagnosis operation on a subsidiary load and feedback-controls the DC/DC converter by setting the voltage control value to a level lower than the output voltage from the subsidiary battery and at least the lower limit of the operating voltage of the ECU. The ECU feedback-controls the DC/DC converter by setting the voltage control value to a level of at least the output voltage of the subsidiary battery in response to completion of engine start-up. Then, the suspension of the defect diagnosis operation on the subsidiary load is canceled and a running permission signal is output.
