The present technology relates to a signal processing device, a signal processing method, a program, and a mobile device enabling to obtain an occupancy grid map in which an appropriate path can be set.

The signal processing device includes: a map creation unit configured to create an occupancy grid map indicating a presence or absence of an object in a unit of a grid on the basis of first sensor data from a first sensor used to detect the object in surroundings of a mobile device; an attribute setting unit configured to set an attribute of the grid of the occupancy grid map on the basis of an attribute of the object; and a correction unit configured to correct the occupancy grid map on the basis of an attribute of the grid. The present technology can be applied to, for example, a system that controls automatic driving.

Systems and methods for displaying connectivity strength for vehicles are disclosed. For instance, the method may include receiving, from an off-board station, connectivity data relating to a connected vehicle, the connectivity data having been received from a plurality of connected vehicles other than the connected vehicle and selected based on relevance to the connected vehicle; identifying a portion of the received connectivity data to display on the connected vehicle; generating a display of the identified portion of the received connectivity data; and displaying on a display unit of the connected vehicle, the generated display of the identified portion of the received connectivity data. The method may also include generating and displaying an updated route based on the received connectivity data.

A method, which can be implemented by a control unit, for carrying out a localization of at least one vehicle by a vehicle-side control unit includes receiving measuring data from at least one sensor, ascertaining at least one marking from the measuring data, and associating the ascertained marking with a marking entered into a digital map for determining a position.

Driving assistance systems, methods, and programs accept an inputted planned travel route from the route guidance system, provide driving assistance of the vehicle on the planned travel route, based on driving assistance map data, and obtain, when versions of the route guidance map data and the driving assistance map data do not match each other, the driving assistance map data whose version matches the version of the route guidance map data from a map provider. Route guidance systems search for a planned travel route based on route guidance map data, provide guidance on the planned travel route, output the planned travel route to the driving assistance system, and obtain, when versions of the route guidance map data and the driving assistance map data do not match each other, the route guidance map data whose version matches the version of the driving assistance map data from a map provider.
