Abstract: A power-supply control device includes: a distribution adjustment unit adjusting electric energy; and a loss comparison unit comparing losses in power running and regeneration and determining, with respect to power running and regeneration, whether a loss in a current state is smaller. Further, the distribution adjustment unit adjusts the electric energy by performing the distribution in accordance with the remaining capacity ratio in the current state in a case where it is determined that the loss in power running is smaller when the current state is a power running state or in a case where it is determined that the loss in regeneration is smaller when the current state is a regeneration state.

Abstract: A power supply of a vehicle includes a first switching element, a second switching element, a third switching element, a first battery, a reactor element, a second battery, a smoothing capacitor, and a controller. When the connection state of the first battery and the second battery is switched from the series connection state to the parallel connection state, the controller is configured to perform a transition control so that a voltage of the smoothing capacitor is decreased to the higher of a voltage of the first battery and a voltage of the second battery, and perform a switching control to turn on the first switching element after a diode of the first switching element is energized.

Abstract: A vehicular heat management system is described and includes: a heater configured to carry out heating of a heat medium and stop the heating, and a heat exchanger configured to carry out heat exchange between lubricant oil for lubricating a speed change apparatus and the heat medium. A heat medium circulator is provided that is configured to switch the heat medium circulation state between a first circulation state where the heat medium circulates through the heater and the heat exchanger, and a second circulation state where the heat medium circulates through the heater and a heater core. An electronic control unit is also provided. When a pre-operation warm-up request to warm up the speed change apparatus and a pre-operation heating request to heat a vehicle cabin are both issued, the electronic control unit causes the heat medium circulator to switch the circulation state such that a warm-up of the speed change apparatus is carried out before heating of a vehicle cabin.
