A drive control device of a hybrid vehicle provided with a motor and an engine is provided. The control device includes a processor configured to execute a target fuel consumption setting module that sets a target fuel consumption according to the number of lapsed days from a given reference timing, an actual fuel consumption calculating module that calculates an actual fuel consumption actually consumed during a specific period from the reference timing, a forcible consumption calculating module that compares the actual fuel consumption with the target fuel consumption, and when the actual fuel consumption is less than the target fuel consumption, calculates a forcible consumption of fuel according to a difference therebetween, and a traveling controlling module that controls the drive of the motor and the engine so that traveling at least with the engine is continuously performed until the fuel is consumed by the forcible consumption.

A communication device acquires schedule information in which a schedule of a user who uses a hybrid electric vehicle is recorded. The schedule information includes a traveling schedule for causing the hybrid electric vehicle to travel in a predetermined period. The predetermined period is a period from when fuel of an engine is refueled to a predetermined deterioration time. When a traveling distance in a long-distance traveling schedule is a first distance, an ECU increases a usage ratio of the engine in the predetermined period than when the traveling distance is a second distance that is longer than the first distance. The long-distance traveling schedule is a schedule included in the traveling schedule and in which the hybrid electric vehicle travels for a predetermined distance or longer.

A device for controlling a hybrid vehicle includes a storage storing a map in which an on reference value and an off reference value of an engine are recorded, a navigation device setting a route from a current location to a destination, a transceiver receiving a speed profile for each section on the route, and a controller dividing the route into a plurality of sections and correcting the map based on the received speed profile for each section to correct a map for determining an on time point and an off time point of an engine based on the speed profile most similar to the driving style of a driver.

Provided are a vehicle and a control method for the vehicle. The vehicle includes an engine, a fuel tank configured to store a fuel for the engine, a grille shutter, and an ECU. The grille shutter is configured to regulate an introduction air from an outside of the vehicle to an inside of the vehicle. The ECU is configured to determine whether or not the fuel is deteriorating. The ECU is configured to control the grille shutter such that an amount of the introduction air in a case where the fuel is deteriorating is larger than an amount of the introduction air in a case where the fuel is not deteriorating.

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 control apparatus of a plug-in hybrid electric vehicle that is provided with a fuel tank, an engine, a battery, and an electric motor. The battery is chargeable by an external power source. The control apparatus includes a fuel deterioration determiner and a regeneration amount limiter. The fuel deterioration determiner determines whether a fuel stored in the fuel tank is deteriorated. The regeneration amount limiter reduces, when the fuel is determined by the fuel deterioration determiner as being deteriorated, a regeneration amount to be less than the regeneration amount of a case where the fuel is determined by the fuel deterioration determiner as not being deteriorated. The regeneration amount is an amount of regeneration of electric power generated by the electric motor upon deceleration of the plug-in hybrid electric vehicle.
