摘要:
An electronic control device for a vehicle configured to be able to rewrite a program related to vehicle control by connecting an external device with the vehicle and by accessing an in-vehicle LAN includes a portable authentication terminal separated from the external device; an in-vehicle authentication system connected with the in-vehicle LAN, configured to authenticate the portable authentication terminal and to be able to transmit a authentication result to the in-vehicle LAN; a repeater configured to relay communications between the external device and the in-vehicle LAN; and a communication authorization unit connected to the in-vehicle LAN and configured to authorize the communications between the external device and the in-vehicle LAN through the repeater if receiving the authentication result of a successful authentication of the portable authentication terminal by the in-vehicle authentication system.

摘要:
A communication system includes a network formed by a plurality of control units, each operated in a high power consumption mode and a low power consumption mode. A selected one or more of the control units act solely or in cooperation with each other to implement a specific function. Each of the selected one or more of the control units related to the specific function is set in the high power consumption mode. Each of the non-selected control units unrelated to the specific function is set in the low power consumption mode.

A fuel cell system of the present invention includes a fuel cell stack, a fuel feeder that provides the fuel cell stack with fuel, a fuel cell DC/DC converter that converts the output voltage of the fuel cell stack to a predetermined voltage and then outputs it, a rechargeable battery that is an electric storage device, and a rechargeable battery DC/DC converter that converts the output voltage of the rechargeable battery to a predetermined voltage and then outputs it. The setting of a voltage at a node at which an output end of the fuel cell DC/DC converter and an output end of the rechargeable battery DC/DC converter are connected together is changeable, and the rechargeable battery is detachable. As a result, the fuel cell system of the present invention has high versatility.

A grid interconnection device includes a relay controller configured to control separation or interconnection of a relay; a receiver configured to receive, from a predetermined transmission path, power failure information containing at least local area information indicating an area in which a power failure occurs; a determination unit configured to determine an occurrence of a power failure in a power distribution system, when the power failure information includes local area information of an area to which the power distribution system belongs; and a detector configured to detect an islanding state. The detector increases detection sensitivity of the islanding state when the determination unit determines the power failure in the power distribution system. The relay controller performs separation control for the relay when the islanding state is detected by the detector.

A large capacity HDD is handled as a portable recording medium. In a state where a portable hard disk (PHD) unit is mounted on a cradle, data is written and read between the PHD unit and a host device. By having a first engagement section on the side of the PHD unit and a second engagement section on the side of a mounting section of the cradle mutually engaged while the PHD unit is mounted on the mounting section, a state where the PHD unit is mounted on the mounting section is maintained.

A rust-preventive water-oil separating cleaner composition contacts a part to be cleaned to which an oil attaches. The composition separates the oil from the part, while providing the part with a rust-preventive property, thus forming an oil layer containing the oil. The composition contains an ethylene oxide additive (X) of monoalkyl amine represented by the general formula (1), and at least one compound (Y) selected from the group consisting of: an N-monoalkyl-N-(2-hydroxyalkyl)-iminoethylene carboxylate having a hydrocarbon group with a number of carbon atoms from 8 to 22; an acylated amino acid salt having a hydrocarbon group with a number of carbon atoms from 8 to 22; an alkyloyl sarcosinate having a hydrocarbon group with a number of carbon atoms from 8 to 22, and a tall oil fatty acid salt
摘要:
An accelerator pedal is positioned at a kickdown position. Then, an output value of a measurement device of an accelerator pedal position sensor is measured. Thereafter, the measured output value of the measurement device is stored in a correction output value storage of the accelerator pedal position sensor along with a corresponding correction value, which is used to correct the measured output value of the measurement device. A couple of fully opened position stop members is provided and is engaged with the accelerator pedal when the accelerator pedal is rotated to a fully opened position. Furthermore, a couple of fully closed position stop members is provided and is engaged with the accelerator pedal when the accelerator pedal is rotated to a fully closed position.
