Abstract: A map difference data delivery system includes a map difference data delivery device and a map data holding device. The map difference data delivery device stores map difference data representing a difference between before and after version update and delivers the map difference data. The map difference data includes map elements updated in the version update and dependent map elements by dating back to update of map elements corresponding to a different version. The dependent map elements are map elements that have a dependent relationship and need to be previously updated to avoid conflict with other map elements when updated. The map difference data delivery device groups data of the dependent map elements that have a dependent relationship in the same version.

Abstract: A map difference data distribution system includes a map difference data distribution device including a map difference data storage unit storing map difference data items and a distribution unit distributing map difference data items, and a map data maintaining device including update unit updating map data based on map difference data items. The map difference data storage unit traces the updated data items and data items having dependent relationships with the updated data items back to the different version updates, and stores the data items as map difference data items. The map difference data distribution device includes a non-updated data extraction unit extracting non-updated data items from the map data maintaining device, a grouping unit grouping the data items in dependent relationships, and a distribution data generation unit generating distribution data by arranging grouped records of non-updated data items from higher priority of map element under specified communication traffic volume.

Abstract: An object detection device includes a condition judgment unit and a noise processing unit. The condition judgment unit judges whether an execution condition for starting an object detection operation is satisfied. The noise processing unit performs a noise-related notification corresponding to an occurrence of limitation of an object detection function due to a high noise state when the condition judgment unit judges that the execution condition is satisfied and when the high noise state is established, the high noise state being a state in which a reception state of extraneous noise, different from the reflected wave received by the plurality of object detection sensors, exceeds a predetermined judgment criterion. The object detection device is configured to perform the noise-related notification more easily when a driving mode of the own vehicle is a backward driving mode than when the driving mode is a forward driving mode.

Abstract: A vehicle control apparatus is provided with a reliability determination unit that determines a reliability related to an own vehicle location as a current location of the own vehicle being in a parking place, using a detection result of a parking space or a parked vehicle around an own vehicle based on image data around the own vehicle captured by a camera; and an own vehicle location determination unit that determines whether the own vehicle location is in the parking place, using a determination result of the reliability determined by the reliability determination unit.
