    Abstract: In a communication method in a wireless communication system configured from a wireless connection providing apparatus (a wireless LAN access point) and a wireless communication apparatus (a wireless LAN client), the wireless connection providing apparatus acquires subscription information for specifying necessary information and includes the subscription information in a control frame notifying surroundings of presence of itself and then transmits the subscription information. The wireless communication apparatus receives the control frame, determines whether the wireless communication apparatus retains information which is specified as being necessary by the subscription information included in the control frame. When the wireless communication apparatus retains the information, the wireless communication apparatus establishes connection to the wireless connection providing apparatus and transmits the information. The subscription information can be stored in an ESSID of a beacon frame, for example.

    Abstract: A controller for an electric motor system is provided. The electric motor system includes a DC power supply, a power converter, a smoothing capacitor, a three-phase AC motor, and a current sensor. The controller includes an electronic control unit. The electronic control unit is configured to control the power converter such that an inter-terminal voltage of the smoothing capacitor matches a first reference value. The first reference value is a value which is determined as the inter-terminal voltage of the smoothing capacitor when a phase current is equal to a second reference value. The electronic control unit is configured to correct a detection value of the current sensor so as to decrease a difference between the detection value and the second reference value when the inter-terminal voltage matches the first reference value and the detection value does not match the second reference value.

  • Publication number: 20170211638
    Abstract: An electronic control unit actuates a clutch by a clutch actuator during traveling of a vehicle when engine torque is lower than a specified threshold. Further, the electronic control unit detects displacement of the clutch, at which a rotational speed difference between an engine speed and an input shaft rotational speed of a transmission becomes a specified rotational speed difference. Furthermore, the electronic control unit corrects the displacement of the clutch when the engine torque is equal to or larger than the specified threshold based on the displacement of the clutch, which is detected. In this way, a torque transmission limit clutch position corresponding to engine torque, at which a vehicle travels less frequently, can appropriately be estimated.

The primary fuel injection and the secondary fuel injection from the fuel injector are successively performed to cause autoignition of an injected fuel of the primary fuel injection and autoignition of an injected fuel of the secondary fuel injection. A temperature region suppressing change of an ignition delay time where a change of ignition delay time with respect to a rise in temperature in the combustion chamber is suppressed appears in the compression stroke at a temperature in the combustion chamber of 700K to 900K. The secondary fuel injection is performed if the temperature in the combustion chamber is a temperature within the temperature region suppressing change of the ignition delay time during the compression stroke.

    Abstract: A front end portion of a connecting member is fixed to a front apron, and a rear end portion of the connecting member is located vertically higher than the front end portion, and is fixed to a rear portion of a cowl. Therefore, when a rear portion of the front apron is elastically deformed rearward, the front end portion of the connecting member is moved rearward. As a result, upward force is applied obliquely upward, to the front end portion of the connecting member, via the connecting member, and a so-called cancelling moment is applied to the rear portion of the cowl. Thus, rotation of the cowl is curbed, and movement of a suspension tower plate in the vertical direction is curbed.
