  • Patent number: 8403687
    Abstract: A data storage device is provided. At least a storage section configured to store information therein and a connection terminal configured to transmit information are mounted on a substrate. A casing accommodates the substrate, the casing is formed with an opening to expose a connection portion of the connection terminal to the outside. A shield plate configured to shield the opening of the casing. A shield plate actuation mechanism is configured to detect a connection state between the connection terminal and a receiving terminal to which the connection terminal is connected and actuate the shield plate. The shield plate actuation mechanism actuates the shield plate to shield the opening when the shield plate actuation mechanism detects that the connection terminal is separated from the receiving terminal.

  • Publication number: 20130054114
    Abstract: The invention relates to an air-fuel ratio control device of an internal combustion engine, comprising a plurality of means for independently introducing into each combustion chamber an exhaust gas discharged from combustion chambers to an exhaust passage. When at least one exhaust gas introduction means is under an exhaust gas introduction shortage state, a target value of an air-fuel ratio of a mixture gas is changed depending on whether an exhaust gas introduction control for introducing the exhaust gas into the combustion chamber by the exhaust gas introduction means is performed.

  • Patent number: 8386152
    Abstract: Upon satisfaction of an idle learning condition, the internal combustion engine system of the invention successively performs learning of an idle control amount and learning of a most delayed angle control amount in this sequence. Upon satisfaction of a most delayed angle learning condition, on the other hand, the internal combustion engine system successively performs learning of the most delayed angle control amount and learning of the idle control amount in this sequence. This arrangement effectively reduces the total time required for completion of learning both the idle control amount and the most delayed angle control amount, compared with the conventional procedure of individually learning only one control amount corresponding to the satisfied learning condition.

  • Patent number: 8386151
    Abstract: An ECU executes a program based on which, when a fuel-supply cutoff control is executed or when a hybrid vehicle travels in a second mode in which the engine is stopped and the hybrid vehicle travels using only the drive power generated by a second MG an intake VVT mechanism is controlled so that a valve phase is brought to the mechanically determined most retarded phase. The phase, which is detected by a cam position sensor, is learned as the most retarded phase.

  • Patent number: 8239121
    Abstract: A stop-time target phase setting unit sets a target phase CAr for an intake valve to a target phase, which is used when an engine is stopped, in response to issuance of an engine stop command. An engine stop control unit generates a series of control commands for an engine stop process in response to issuance of the engine stop command. A motoring command unit generates a first MG control command for rotating the engine using a motor for a predetermined period Tm that is counted by a timer in response to issuance of the engine stop command. Thus, the engine idles even after fuel combustion stops. In this way, the period in which the valve phase can be changed by a VVT mechanism is increased. As a result, a valve phase when the engine stops is reliably brought to the target phase that is suitable for next engine starting.

  • Patent number: 7971668
    Abstract: In a hybrid vehicle 20, when a deceleration demand based on accelerator-off is made in selecting an S position that allows arbitrary selection of shift positions SP1 to SP6, and fuel cut cannot be prohibited from a state of a battery 50, an engine 22 and motors MG1 and MG2 are controlled so that a driving force based on a torque demand Tr* is outputted with the fuel cut (Steps S410, S420, S360 to S400). When the deceleration demand based on the accelerator-off is made in selecting the S position, and the fuel cut can be prohibited from the state of the battery 50, the engine 22 and the motors MG1 and MG2 are controlled so that the engine 22 substantially performs self-sustaining operation at a target rotation speed Ne0 and a driving force based on the torque demand Tr* is outputted (Steps S340 to S400).

  • Patent number: 7958858
    Abstract: A variable valve timing system changes a valve phase by reducing an operation amount of an actuator at a speed reduction ratio that varies depending on a phase region. When the valve phase is outside a region in which the ratio of the amount of change in the phase with respect to the operation amount of the actuator is low, namely a high speed reduction ratio, the actuator may be operated due to, for example, a reaction force applied to a camshaft, and an undesirable valve phase change may result. Accordingly, when an engine stop command is possibly issued, the target phase value is restricted to a region more delayed than a phase restriction value set in consideration of the amount by which the valve timing can be changed from when an engine stop command is issued until when the engine is stopped.

  • Patent number: 7909008
    Abstract: In an intake valve phase control after an engine stop command is issued, a stop-time phase is used as a target value. In the intake valve phase control, when the mode changeover condition is not satisfied, and an electric motor that serves as an actuator is not in a locked-state, the highest-speed mode, in which the amount of electric power supplied to the electric motor is fixed to the maximum value, is selected to reliably change the intake valve phase by a required amount. Then, the intake valve phase comes close to the stop-time phase and the mode changeover condition is satisfied, the control mode is changed from the highest-speed mode to the normal mode to set the control phase to the stop-time phase with higher accuracy, and the feedback control over the intake valve phase is executed.

  • Patent number: 7814743
    Abstract: In an engine 5 including an in-cylinder injector, the valve timing of an intake valve is retarded by VVT (Variable Valve Timing) controlled by an engine ECU to decompress in a combustion chamber at engine startup. In accordance with a configuration in which the valve timing of intake valve is advanced in a stepped manner from an initial set value, fuel injection from in-cylinder injector is inhibited during the time when the advance is equal to or below a predetermined standard value, and fuel injection from in-cylinder injector is allowed when exceeding the predetermined standard value, whereby degradation in the exhaust emission level in accordance with start time decompression control can be suppressed.

  • Publication number: 20100037842
    Abstract: An idling-time target phase setting unit (130) variably sets a target phase based on a target idle speed that is set by a target idle speed setting unit. (110) Especially, when the target idle speed is lower than a predetermined rotational speed and operating noise of a variable valve timing mechanism (2000) is easily heard by, for example, a driver, the.idling-time? target phase setting unit (130) sets the target phase so that a range, in which the valve phase is allowed to change, is restricted within a phase region where a speed reduction ratio is high and the operating noise is relatively low.

  • Patent number: 7565939
    Abstract: In a hybrid vehicle of the invention, the control procedure corrects an idling intake air flow Qidl to enable an engine immediately after its start to generate an output power Pe that is substantially equivalent to an engine power demand Pe*. After the correction, the control procedure controls the engine to have an intake air flow Qe with reflection of an intake air flow correction value Qec and controls a motor MG1 to generate electric power by using the output power Pe of the engine and to charge a battery with the generated electric power within an input limit Win of the battery. The control of the invention ensures that the output power Pe of the engine does not exceed the engine power demand Pe* in restriction of the charge level of the battery. This arrangement effectively prevents the state of charge SOC of the battery, which is charged with the electric power generated by the motor MG1, from exceeding the input limit Win.
