A hybrid vehicle includes an engine, a fuel tank, a motor, a battery, a charger, and a notification mechanism. The battery is configured to supply electric power to the motor. The charger is configured to carry out external charging that charges the battery by use of electric power from an external power source. The notification mechanism is configured to notify, to an outside of the vehicle, information on a use index indicative of a degree of use of external charging in a predetermined time period.

In the present invention, a display device is provided with a fuel gauge (40) that displays the amount of fuel remaining in a fuel tank (24) (remaining amount) of a hybrid vehicle (10) that is provided with an engine (13) that consumes fuel supplied from the fuel tank (24) and generates power by driving wheels (15) or rotating a motor (11), the hybrid vehicle being provided with a non-traveling/non-power generating mode, or in other words, a fuel consumption mode or an engine maintenance mode in which the engine (13) is forced to run and consume fuel for purposes other than traveling or generating power. Of the fuel (41a) displayed in the fuel gauge (40), the region (41aa) corresponding to the amount of fuel consumed in the non-traveling/non-power generating mode is displayed so as to be distinguishable by color from another region (41ab), and thus, it is possible to display as a status and in a visually clear manner a state in which the engine (13) continues to run, and it is possible for the driver to confirm how much fuel is being consumed in the non-traveling/non-power generating mode, thereby providing the driver with peace of mind.

A reservoir tank for a vehicle includes an upper body provided with an inflow pipe and a lower body provided with a discharge pipe, the upper and lower bodies being assembled to each other. An inside of the upper body and the lower body is installed on a coolant passage while being partitioned into a plurality of chambers, where one side of an upper portion of the upper body is provided with the inflow pipe parallel therewith, and the upper body is integrally connected to a guide pipe in a vertical direction to the inflow pipe to downwardly guide coolant. The lower body is provided with a guide rib corresponding to the guide pipe to enclose an outer side of a tip portion of the guide pipe while the guide rib is spaced apart from the outer side of the tip portion of the guide pipe at a predetermined interval to form the coolant passage between the guide rib and the guide pipe.

A vehicle includes a high voltage battery, a charger and an ECU. When electric power from an external power supply is equal to or less than first predetermined electric power and first power feeding control to feed electric power to a low voltage system power line is performed, the ECU is configured to control the charger to: continue the drive of the charger when a first predetermined time has not elapsed from a start of the first power feeding control or when charged electric power of the high voltage battery is greater than second predetermined electric power that is smaller than the first predetermined electric power after the first predetermined time has elapsed; and stop the drive of the charger when the charged electric power of the high voltage battery is equal to or less than the second predetermined electric power after the first predetermined time has elapsed.

An electronic control unit is configured to i) turn off a charging relay when a charger is disconnected from an external power source while external charging is in progress which is started when the charger is connected to the external power source and the charging relay is turned on while a system is off and in which a battery is charged with electric power from the external power source by the charger, and ii) set the period from the disconnection of the charger from the external power source to the turn-off of the charging relay to be longer when preliminary air conditioning is in progress than when preliminary air conditioning is not in progress.

A vehicle control system includes a controller that is programmed to, in response to an accelerator lift-pedal event, generate a drag torque, with at least one of an engine and electric machine, having a magnitude that is based on a deceleration fuel shut-off torque of the engine and a desired power output of the electric machine, and limit the drag torque to a threshold value that is based on the deceleration fuel shut-off torque.

This in-vehicle DC-DC converter is configured from: a power conversion unit that transmits/receives power between a low-voltage system secondary battery and a high-voltage system secondary battery; low-voltage system AD converters and high-voltage system AD converters, which convert analog values of the currents, voltages, and temperatures of the low-voltage system secondary battery and the high-voltage system secondary battery into digital values; an input switching unit that switches analog values of the high-voltage system secondary battery into analog values of the corresponding low-voltage system secondary battery; and a calculation unit that compares the digital values of the low-voltage system AD converters and the digital values of the high-voltage system AD converters with each other. In the switched state, failure diagnosis of the AD converter is performed by comparing the digital values of the low-voltage system AD converters and the digital values of the high-voltage system AD converters with each other.

A wire harness includes a tubular external member and one or a plurality of conduction paths inserted into the external member and protected by the external member. The external member includes at least one fixed form insertion part in which an inside width is wider than an outside width of the one or the plurality of conduction paths, and a plurality of narrow-width insertion parts which are elastically deformable and in which an inside width is narrower than the outside width of the one or the plurality of conduction paths. The plurality of narrow-width insertion parts are arranged along a tube axial direction alternately and integrally with the at least one fixed form insertion part.

A hybrid vehicle powertrain includes an internal combustion engine, an electric traction motor and a transmission. A first flexible coupling drivingly connects the internal combustion engine to the transmission, and a second flexible coupling drivingly connects the electric traction motor to the transmission.

Provided are an inverter device deterring PWM voltage error even if high inverter output frequencies are used for overmodulation driving and an electric vehicle equipped with the inverter device. In an angular section where the output voltage from an inverter device is linearly approximated with the zero cross point as the center thereof, a PWM generator in the inverter device changes either the time interval between the centers of PWM ON pulses or the time interval between the centers of PWM OFF pulses depending on the inverter operation state. An electric vehicle is equipped with the inverter device, which drives a motor.
