  • Patent number: 9856816
    Abstract: When the temperature in a cylinder of an engine is low, the fuel injection amount of fuel that has a low vapor pressure and is less likely to be vaporized is increased, and the fuel injection amount of fuel that has a high vapor pressure and is more likely to be vaporized is reduced, so that the start timing of the engine can be kept constant. When the temperature in the cylinder is high, the fuel injection amount of the fuel that has a low vapor pressure and is more likely to be decomposed is reduced, and the fuel that has a high vapor pressure and is less likely to be burned (decomposed) is increased, so that the start timing of the engine can be kept constant. Thus, the start timing of the engine is kept constant irrespective of the fuel property, and deterioration of the drivability can be curbed.

  • Publication number: 20170299399
    Abstract: An in-vehicle terminal sends a speech input from a voice input unit as a voice signal to a relay server using a short-range wireless communication unit. The relay server converts the voice data received from the in-vehicle terminal into a string with a voice recognition unit, and makes an inquiry, via a communication unit, to an address database of a database server as to whether the string is a geographical condition. If the string converted by the voice recognition unit is a geographical condition based on the inquiry result of the communication unit, a POI data base is searched based on the geographical condition and a stored non-geographical condition, and the geographical condition is stored in a search history. If the string is a non-geographical condition, the POI database is searched based on the non-geographical condition and the geographical condition stored in the search history, and the non-geographical condition is stored in the search history.
