  • Publication number: 20250209914
    Abstract: When the traffic sign is not recognized from the image information, a traffic rule output to the display device is generated based on the travel road sign included in the map information and indicating the traffic sign provided on the traveling road of the vehicle. When the traffic sign is recognized from the image information, the traffic rule is generated based on the image-recognized sign indicating the traffic sign included in the image information. Based on the image-recognized sign, it is determined whether the travel road sign is correct. When it is determined that the travel road sign is an error, the distance or time for continuing outputting the traffic rule to the display device is extended as compared with the case where it is determined that the travel road sign is correct.

  • Patent number: 12289583
    Abstract: Audibility of an outside sound needed for a driver inside an automobile to apprehend a danger and obtain a grasp of a situation necessary for driving is improved. A sound collection and emission apparatus (10) emits, on the basis of an outside acoustic signal which emanates from a sound source outside an automobile (90) and arrives at the automobile (90), an inside acoustic signal which is an acoustic signal derived from the outside acoustic signal to inside the automobile (90). A sound collection unit (M1) collects the outside acoustic signal. A sound emission unit (S1) emits the inside acoustic signal. A danger sound detection unit (11) determines whether the outside acoustic signal has a feature representing a danger defined in advance. A control unit (12) performs control that emits the inside acoustic signal from the sound emission unit (S1) such that a driver of the automobile (90) is capable of perceiving the danger if the outside acoustic signal is determined to represent the danger.
