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.

摘要： A power plant outputs motive power by driving a motor (22) using electric power from a direct-current power source (32). When the direct-current power source (32) has a low temperature, the direct-current power source is rapidly heated, whereby the performance can fully be demonstrated. In the power plant in which a capacitor (30) is installed so as to connect a positive electrode bus (26) and a negative electrode bus (28) of an inverter circuit (24) and the direct-current power source (32) is also installed so as to connect the negative electrode bus (28) of the inverter circuit (24) and a neutral point of the motor (22), when a power source temperature (Tb) of the direct-current power source (32) detected by a temperature sensor (50) is less than or equal to a threshold temperature (Tblow) at which supply of required electric power to the motor (22) is possible, an electronic control unit (40) sets a voltage between terminals of the capacitor (30) higher than normal and also sets a frequency of a carrier wave lower than normal, and performs switching control of transistors (T1 to T6) Thus, a ripple of a neutral point current which flows into the direct-current power source (32) can be increased, whereby it is possible to promote calorification of the direct current power source (32).

摘要： On end of a reactor (L1) is connected to a positive electrode of a battery (B1) and the other end is connected to a power line via a transistor (Q1) and to the ground via a transistor (Q2). By PWM control of the transistors (Q1, Q2), an arbitrary increased voltage is obtained in the power line. It is possible to obtain an optimal inverter input voltage (power line voltage) according to the motor drive state, thereby increasing efficiency. Thus, it is possible to optimize the inverter input voltage according to the motor drive condition.
