Abstract: PROBLEM TO BE SOLVED: To prolong running distance of a vehicle from the time when the amount Fu of remaining fuel is reduced. SOLUTION: The vehicle operates an engine at set target operation point by setting the target operation point composed of target rotational speed Ne* and target torque Te* of the engine 22 (S140) using an operation line for fuel small amount time changed to a low torque side with respect to a part having predetermined rotational speed or more among operation lines for usual time when the amount Fu of remaining fuel is less than a threshold value Fref (S120).

Abstract: PROBLEM TO BE SOLVED: To improve the startability of an internal combustion engine which can be operated at a high expansion ratio with a substantial compression ratio being lower by quickening a timing for closing an intake valve when compressing intake air in a cylinder after expanding it once. SOLUTION: When the operation stop of the engine is instructed, the engine is stopped at a position deviating from a region where intake air is expanded when tending to a compression stoke after the intake valve is closed, for example, at a target stop position which is set as a position with the intake valve closed (S210, S220). Thus, negative pressure is produced in the cylinder to allow the entry of air therein during the stop of the engine, preventing the compression ratio from being higher in the first compression stroke at the next start. As a result, knocking is prevented and the next start of the engine is smoothed. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To make a battery fully exhibit its performance by managing its temperature to be in a more proper state.
SOLUTION: The charging and discharging of the battery is controlled by setting targeted charging and discharging capacity Pch*, based on the remaining capacity SOC of the battery, using a map showing the relation that the lower the temperature of the battery, with the larger the inclination of the target charging and discharging capacity Pch* with respect to the changes in the remaining capacity SOC becomes, the larger hysteresis to the change of the remaining capacity SOC becomes. By this control, the lower the temperature of the battery is, the more actively the battery is charged and discharged. Moreover, hysteresis is made larger, when the charging and discharging are performed actively so that the battery in a low temperature can be warmed effectively and its performance can be put forth sufficiently, while preventing the frequent switching of the charging and discharging.
