  • Patent number: 10953794
    Abstract: A loudspeaker 14 outputs a warning sound for announcing the presence of a vehicle to the outside of the vehicle. A travel start detection unit 122 detects travel start of the vehicle. A sound pressure control unit 124 controls sound pressure of the warning sound to be output from the loudspeaker 14, depending on travel status of the vehicle. The sound pressure control unit 124 makes the loudspeaker 14 output the warning sound during stopping of the vehicle, and increases the sound pressure of the warning sound upon detection of travel start of the vehicle. This makes it possible to announce the travel start of a low-noise vehicle such as an electrically powered vehicle, without making the surroundings feel unnatural.

  • 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.
