Abstract:
A vehicle includes: a motor generator for generating driving power for traveling thereof; an ECU for controlling the motor generator; and an inclination detecting unit for detecting inclination of a road surface. The ECU performs power changing driving in which the vehicle is traveled while switching the motor generator between a first state (high output state) and a second state (low output state). In the first state (high output state), driving power of a first level is generated. In the second state (low output state), the driving power is made smaller than that in the first state. When it is recognized that the vehicle is traveling on an uphill road based on the inclination detected by the inclination detecting unit, ECU sets the driving power in the first state to be larger than that set when the vehicle is traveling on a flat road.
Abstract:
A vehicle includes an engine and a motor generator generating driving power for running, and an ECU for controlling the engine and the motor generator. If user requested power and a vehicle speed are substantially constant when inertial running control is selected by a user, the ECU causes continuous driving power operation to be performed on the engine in which the engine is driven to continuously generate constant driving power, and causes driving power variation operation to be performed on the motor generator in which the motor generator is alternately switched between a low output state and a high output state in terms of driving power, thereby running the vehicle. As a result, energy efficiency during vehicle running can be improved.
Abstract:
A control apparatus for a power unit equipped with an internal combustion engine and outputs a power. The control apparatus according to the invention starts engine operation when the required power becomes equal to or larger than an engine start threshold during engine stop, and stops engine operation when the required power becomes equal to or smaller than an engine stop threshold during engine operation. The internal combustion engine is equipped with a catalyst. When the purification capacity of the catalyst is lower than a start threshold correction threshold, a value smaller than a reference engine start threshold is set as the engine start threshold. When the purification capacity of the catalyst is equal to or higher than the start threshold correction threshold, a value equal to the reference engine start threshold or a value larger than the reference engine start threshold is set as the engine start threshold.
Abstract:
An ECU is mounted in a vehicle including an in-cylinder injection type engine having an EGR device and a motor. The ECU calculates vehicular requested power Preq and the ECU calculates a requested engine operating point OPreq based on the vehicular requested power Preq, and if the requested engine operating point OPreq falls within an EGR range, the ECU sets the requested engine operating point OPreq exactly as a commanded engine operating point OPcom, whereas if the requested engine operating point OPreq falls within a non-EGR range, the ECU corrects the requested engine operating point OPreq to fall within the EGR range and sets the corrected engine operating point as the commanded engine operating point OPcom. The ECU then controls the engine and the motor so that an actual engine operating point coincides with the commanded engine operating point OPcom while satisfying the vehicular requested power Preq.
Abstract:
A hybrid vehicle includes an engine and a motor each for generating vehicle driving power. An operation region indicated by rotational speed and torque of the engine includes: an normal region in which a fuel injection amount is calculated in accordance with a stoichiometric air-fuel ratio; and an amount increase region in which an amount of fuel is increased compared with the normal position so as to suppress temperature increase of a catalyst. A control device calculates a total required power of the vehicle depending on the vehicle state, and determines an engine operation point in accordance with the total required power. When the engine operation point is in the OT amount increase region, the engine operation point is changed to fall within the normal region by decreasing the engine output power. An output power of the motor is determined to compensate the decrease of the engine output power and secure the total required power.
Abstract:
A first computer is provided that executes a plurality of virtual machines (VMs), a storage device, and a second computer is provided that applies patches to OSs (operating systems) operating upon the VMs to the VMs. The storage device holds storage regions (golden images (GIs)) that store data of the OSs operating upon the VMs at certain time instants, a storage region that stores patches applied to the OSs of the VMs after those certain time instants, and snapshots of the GIs. Patches applied to the OSs of the VMs accessed in the snapshots are stored in the storage pool. The second computer selects, as a GI to be a source of acquisition of snapshots, a GI to which are applied patches of a combination that can be created from patches applied to the OS of some VM, and deletes patches that are patches applied to the selected GI, and that moreover, among the patches applied to that VM, are stored in the storage pool.

Abstract:
One of a backup apparatus and a storage system performs control to store backup data in a storage system which belongs to an organization and/or location different from an organization and/or location to which a storage-target storage system for original data belongs, based on information (P) and/or (Q) below: (P) information relating to original data, and information relating to backup data, which is a copy of the original data; (Q) information indicating an organization and/or location to which each storage system belongs.
Abstract:
A storage system maintains a journal and a snapshot of one or more data volumes. Two journal entry types are maintained, an AFTER journal entry and a BEFORE journal entry. Two modes of data recovery are provided: “fast” recovery and “undo-able” recovery. A combination of both recovery modes allows the user to quickly recover a targeted data state.
Abstract:
The correspondence between a plurality of virtual storage positions in a virtual volume for logically holding a snapshot image of a main volume in which data elements transmitted from a higher-level device are written and a plurality of address information elements indicating a plurality of actual storage positions of a plurality of data elements constituting the snapshot image is managed. In the initial backup, all the data elements stored in all the actual storage positions indicated by a plurality of address information elements are backed up, then storage positions where a difference has occurred between the virtual volume and the backup destination storage device is managed, and in the next and subsequent backups, data elements on the storage positions specified from the address information elements corresponding to the differentially managed storage positions are backed up.
