  • Patent number: 8423213
    Abstract: A vehicle control device for controlling a vehicle drive apparatus, the vehicle control device configured with a phase determining mechanism that determines the end of the torque phase in a shift operation, and a rotary electrical machine control mechanism that controls the torque of the rotary electrical machine using a variation of input torque. The vehicle control device is also configured with an engagement control mechanism that provides feedback controlling supplied oil pressure to an engagement side element as an engagement element on a side to be engaged after switching of shift speeds so that the rotation speed change rate of the input member becomes the target rotation speed change rate.

  • Patent number: 8352109
    Abstract: A vehicle control device for controlling a vehicle drive apparatus, the vehicle control device configured with a release control mechanism that provides feedback controlling supplied oil pressure to a release side element, and an engagement control mechanism that increases supplied oil pressure to an engagement side element as an engagement element on a side to be engaged in a state that the differential rotation speed is substantially constant. The control device is further configured with a phase determining mechanism that determines if the torque phase has started when a condition that a phenomenon accompanying a change of the differential rotation speed due to increase of the supplied oil pressure to the engagement side element is detected is met.

  • Publication number: 20120304735
    Abstract: Provided is a gas sensor in which a connection terminal can be favorably fitted onto a cylindrical sensor element without causing a breakage of the connection terminal. An oxygen sensor (1) includes an outer connection terminal (29) having an outer fitting portion (53), an extension portion (55) extending inwardly from an axially intermediate point of the outer fitting portion (53) and pulling prevention portions (75) and (77) formed on rear end parts of the outer fitting portion (53) at positions adjacent to the extension portion (55). When the extension portion (55) of the outer connection terminal (29) is inserted in and pulled out from a through hole (23) of a separator (27), the extension portion (55) can be prevented from further pulling in the through hole (23) by contact of the pulling prevention portions (75) and (77) with a front end surface of the separator (27).

  • Publication number: 20100082208
    Abstract: An automatic transmission control system calculates a sustention output, needed to sustain a vehicle speed, based on the running resistance, calculates a request output based on, for example, an accelerator pedal angle, calculates a current gear ratio maximum output, which is a maximum output of a vehicle at the current gear ratio, based on the maximum output performance of the engine, and also calculates a post-upshift maximum output that is the maximum output of the vehicle at a gear ratio resulting from an upshift. When a first value based on the sustention output, request output, and a reserve output becomes larger than a second value based on the current gear ratio maximum output, a downshift is decided. When a third value based on the sustention output, request output, and reserve output becomes smaller than a fourth value based on a post-upshift maximum output, upshift is decided.

  • Patent number: 7337228
    Abstract: An information processing method and apparatus for enabling more prompt sign-up. A network management server at step S62 received am equipment serial number from an information processing apparatus and, at step s63, references a database to retrieve a received equipment serial number. If the equipment serial number has not been found, the program moves to step S16 where a command for initiating manual setting is sent to an information processing apparatus. If the equipment serial number has been found, the program moves to step S81 to verify whether or not the admittance made or admittance not as yet made, recorded in the database in association with the equipment serial number received is admittance made. If the verified result indicates admittance not as yet made, the program moves to step S82 where the network management server sends an automatic setting initiating command to the information processing apparatus.

  • Publication number: 20070128955
    Abstract: A crimp contact, a gas sensor including the crimp contact for outputting a signal from a sensing portion of a sensor element to an external device, and a method for manufacturing the crimp contact. The crimp contact includes a barrel portion crimped so as to fix a plurality of lead core wires (16) of an electrical lead connected to the external device. A hold portion constituting the barrel portion is formed such that the lead core wires 16 of the electrical lead are disposed in an U-shaped hold portion 77 so as to be crimped between an anvil 120 and a crimper 121. An outer surface of the U-shaped hold portion 77 has a plating layer 85 thereon to thereby constantly secure slidability between a sliding face of the crimper 121 and the outer surface of the U-shaped hold portion 77.
