  • Publication number: 20240129713
    Abstract: An apparatus receives, from a user terminal of a user using a SIM provided by a carrier having a communication infrastructure, a diagnosis request with respect to the SIM. In accordance with the diagnosis request, the apparatus, with respect to one or a plurality of instances included in the communication infrastructure, transmits an acquisition request for condition information concerning the condition of a wireless communication service associated with the SIM to be diagnosed. Each of the instances that have received the acquisition request acquires the condition information with respect to the SIM to be diagnosed, and transmits the condition information to the apparatus. The apparatus performs a diagnostic process on the basis of the received condition information, and transmits to the user terminal display information for a diagnostic result display screen based on the condition information.

  • Publication number: 20230242089
    Abstract: A control apparatus for a vehicle that includes an engine, an electric motor and a clutch provided between the engine and the electric motor. An engine-start delay control is executed in a case in which a requested drive amount is realized by only a torque of the electric motor and a first starting manner is being selected as an engine starting manner. Then, in a case in which a predetermined time elapses from initiation of the engine-start delay control, the engine-start delay control is terminated and the engine is started in the first starting manner. On the other hand, in a case in which the engine starting manner is switched from the first starting manner to a second starting manner before the predetermined time elapses from the initiation of the engine-start delay control, the engine-start delay control is terminated and the engine is started in the second starting manner.

  • Patent number: 9481356
    Abstract: When a K0 clutch 34 is interrupted to stop a direct injection engine 12 during vehicle running, if a stop position of a crankshaft 114 is out of a range of a target stop range ?target, the once interrupted K0 clutch 34 is temporarily frictionally engaged to slightly rotate the crankshaft 114. As a result, the crankshaft 114 stopped near compression TDC (top dead center) is rotated to and stopped in a minimum region of pumping energy in combination with a pumping action. Since the minimum region of the pumping energy overlaps with the target stop range ?target suitable for ignition start associated with a small assist torque at the time of engine start, the ignition start can properly be performed at the next engine start and the assist torque at the time of engine start can be reduced.
