Abstract: A relay drive control device is configured to control drive of a relay for connecting a battery mounted on a vehicle and an external power supply. The relay drive control device includes a controller configured to, when driving the relay, supply an output voltage of the battery to the relay after increasing the output voltage to a voltage value at which the relay is drivable.

Abstract: An engine and a step up-down converter are controlled such that a counter-electromotive voltage of a first motor becomes higher than direct current-side voltages of a first inverter and a second inverter and thereby torque for forward travel is output from the first motor to a driving shaft through a planetary gear set, when an accelerator is on during specified travelling with gates of the first inverter and the second inverter being cut off and the engine being operated. The engine and the step up-down converter are controlled such that the rotational speed of the first motor becomes smaller and the voltage of the high voltage-side electric power line becomes lower when the accelerator is off than when the accelerator is on during the specified traveling.

Abstract: The automobile controller notifies the controller of the power feed device (power supply controller) of the charging voltage prior to charging the battery. After receiving the charging voltage, the power feed controller raises the voltage at the output end of the power supply device to the supply voltage that is lower than its own rated output voltage and the charging voltage. The automobile controller monitors the voltage at the output end to identify the supply voltage while the power feed controller performs a ground fault check. The automobile controller (1) charges the battery with electric power of the supply voltage if the supply voltage is equal to the charge voltage, and (2) drives a boost converter to reduce the supply voltage to the charge voltage if the supply voltage is lower than the charge voltage, and then charge the battery with electric power from the power feed device.

Abstract: An engine is controlled such that a first motor rotates at a rotational speed that causes a counter-electromotive voltage of the first motor to be higher than direct current-side voltages of a first inverter and a second inverter, and the first motor outputs torque to a driving shaft through a planetary gear set when an accelerator is on during specified travelling with gates of the first inverter and the second inverter being cut off and an engine being operated. When the accelerator is turned off during the specified traveling, fuel injection of the engine is stopped.
