  • Publication number: 20230379991
    Abstract: An in-vehicle terminal performs a processing related to a remote service of a vehicle. When a first event occurs, a controller of the in-vehicle terminal determines whether short-range wireless communication between the vehicle and a user terminal is being established. In a case where it is determined that short-range wireless communication between the vehicle and a user terminal is not being established, the controller executes a first process. On other hands, in a case where it is determined that short-range wireless communication between the vehicle and the user terminal is being established, the controller executes a second process different from the first process.

  • Publication number: 20230267785
    Abstract: An information processing device includes a processor. The processor detects start of a first application program in a user terminal. The first application program is used to perform a remote operation of a vehicle. The processor is configured to transmit, when the start is detected, an instruction signal to a communication terminal of the vehicle. The instruction signal causes one or more electronic control units mounted on the vehicle to transition from a sleep state to an activated state.

  • Patent number: 11395067
    Abstract: A microphone-loudspeaker integrated apparatus includes a plurality of microphones, a loudspeaker, and a synthesis unit. The loudspeaker is disposed between the plurality of microphones. The synthesis unit synthesizes sounds collected from the plurality of microphones. A distance between the plurality of microphones is set so as to fall within a range within which sound at a frequency needed for recognizing voice is collectable and within a range within which a noise amount due to vibration of the loudspeaker is allowable, when voice recognition is performed based on sound obtained through synthesis by the synthesis unit.
