  • Publication number: 20220316429
    Abstract: A control unit diagnoses a failure of a fuel storage unit that seals a fuel tank and a processing unit that processes fuel evaporative gas in the fuel tank. A first pressure detection unit of the fuel storage unit detects the pressure of the fuel tank. A second pressure detection unit of the fuel storage unit is disposed at a position different from the first pressure detection unit, and detects the pressure of the fuel tank. The control unit specifies a failure portion of the fuel storage unit and the processing unit based on a change in either one or both of a first pressure value detected by the first pressure detection unit and a second pressure value detected by the second pressure detection unit when the pressure of the fuel tank is changed.

  • Publication number: 20220248223
    Abstract: A RAN node (2) receives a message containing a Non-Access Stratum (NAS) security parameter from a radio terminal (1), during a procedure in which the radio terminal (1) requests the RAN node to broadcast on-demand system information. The RAN node (2) sends an authentication request message containing the NAS security parameter to a core network node (3), in order to request authentication of the radio terminal (1). The RAN node (2) broadcasts the on-demand system information in response to receiving from the core network node (3) an authentication response message indicating successful authentication of the radio terminal (1). This can contribute to, for example, preventing on-demand SI from being broadcast in response to a request from a malicious radio terminal.

  • Patent number: 10781767
    Abstract: A fuel injection control apparatus switches between MPI and DI+MPI modes. The apparatus includes a unit calculating a DI direct combustion rate that is the rate of that portion of the amount of DI injection corresponding to a fuel combusted instead of adhering to inside of the cylinder, and a unit calculating a cylinder vaporization rate that is the rate of the amount of that portion of the fuel adhering to the inside of the cylinder which vaporizes. The former unit controls fuel injection based at least on the DI direct combustion rate and the cylinder vaporization rate. When the mode is switched between the MPI mode and the DI+MPI mode, the former unit corrects the DI direct combustion rate or the cylinder vaporization rate to set the amount of fuel injection to a value different from that set when the fuel injection modes are maintained.
