  • Publication number: 20240157961
    Abstract: A vehicle system: estimates a position of a host vehicle; acquires, from outside of the host vehicle, a probe data map generated based on probe data; recognizes periphery information indicating a periphery of the host vehicle using a detection result of an autonomous sensor; specifies an attention point using the probe data map; recognizes a driver status; compares feature information indicated by the probe data map with the periphery information of the host vehicle and determines whether the probe data map has a high quality or a low quality; determines, based on the driver status, whether the driver performs a safety confirmation for the attention point indicated by the probe data map when the probe data map is determined to have the high quality; and notifies the driver of a determination result of the safety confirmation.

  • Publication number: 20240017736
    Abstract: A vehicle control device is for a vehicle. The vehicle has a user-involvement mode and an automated driving mode as driving modes. The user-involvement mode is a driving mode in which a user sitting in a driver's seat is required to monitor a front of the vehicle. The automated driving mode being a driving mode in which the user is not required to monitor the front of the vehicle. A processor acquires information of a current driving mode, and acquires a residual amount of energy for driving. The processor may perform a notification related to a decrease in the residual amount of energy based on a fact that the residual amount of energy becomes equal to or less than a predetermined threshold.
