    摘要: A control apparatus of a DC-DC converter includes a reactor and a switching element, repeats an accumulation and a discharge of energy of the reactor by a switching operation of the switching element, and converts a direct-current input voltage to acquire a direct-current output voltage. The control apparatus includes: a current value acquiring unit that acquires current values of the reactor in a current rising section and a current descending section of a current waveform of the reactor at a time interval of a half of a switching period of the switching element; and a center value estimating unit that estimates a center value of a current of the reactor based on the current values acquired in the current rising section and the current descending section.

    摘要: A hybrid vehicle is identified as a vehicle including a first drive unit (4) driven by a first energy source, a first reservoir unit (201 ) reserving the first energy source, a first connection unit allowing a first energy source supply unit to be connected thereto and guiding the first energy source supplied from the first energy source supply unit to the first reservoir unit (201), a second drive unit (MG1, MG2) driven by a second energy source different from the first energy source, a second reservoir unit (B) reserving the second energy source, and a second connection unit allowing a second energy source supply unit to be connected thereto and guiding the second energy source supplied from the second energy source supply unit to the second reservoir unit. The first connection unit is provided at one lateral surface of the vehicle and the second connection unit is provided at the other lateral surface of the vehicle, the one lateral surface and the other lateral surface being arranged in a width direction of the vehicle.
