A controller that controls charging of a power storage in a vehicle includes an obtaining unit that obtains a fee table showing charge fee information for each of a plurality of maximum supply powers of a power feed facility outside the vehicle before start of charging of the power storage with the use of the power feed facility, a setting unit that sets a criterion for selection of maximum supply power of the power feed facility, a selector that selects one maximum supply power in the fee table in accordance with the criterion set by the setting unit, and a notification unit that notifies the power feed facility of the maximum supply power selected by the selector.

Vehicle and charging method

In a control device for a vehicle, the vehicle is configured to charge an electric power storage device with an electric power supplied from a charger. The control device includes an input and output circuit and a control circuit. The input and output circuit is configured to input predetermined signal and output the predetermined signal. The control circuit is configured to prepare for charging of the electric power storage device by controlling transmission and reception of signals through the input and output circuit according to a predefined communication sequence. The control circuit is configured to proceed with the predefined communication sequence by transmitting the second signal to the charger even when the vehicle does not receive the first signal at the predetermined timing.

Control device for vehicle, vehicle, and control method of vehicle

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.

Relay drive control device, control method, and storage medium

A control apparatus of a vehicle includes an input and output port configured to input and output signals transmitted and received between the vehicle and a charger and an electronic control unit configured to control the transmission and reception of the signals through the input and output port according to a communication sequence defined in order to charge an electric power storage device. The communication sequence defines that the vehicle proceeds with the communication sequence based on a content represented by the signal received by the vehicle from the charger. The electronic control unit is configured to proceed with the communication sequence regardless of the content represented by a predetermined specific signal when the signal received from the charger is the predetermined specific signal.

Control apparatus of vehicle, vehicle including control apparatus, and control method of vehicle

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.

Hybrid vehicle and control method therefor

In a hybrid vehicle including an engine capable of outputting motive power to driving wheels, a motor capable of outputting motive power to the driving wheels and configured to generate a counter-electromotive voltage with rotation, an inverter that drives the motor, an electric storage device connected to the inverter through an electric power line, three phases of the inverter are turned on when an accelerator is turned off while the hybrid vehicle travels with a gate of the inverter being cut off and the engine being operated.

Hybrid vehicle

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.
