摘要： A vehicle control device has a processor configured to determine whether a first road exists where the vehicle is to exit from the traveling road, and when a first road exists, to set a lane change schedule zone based on a first connecting location, to determine whether a second road located on the same side of the traveling direction of the vehicle as the first road exists between the current location of the vehicle and the first connecting location, to change a start location of the lane change schedule zone based on a second connecting location, when a second road exists and the start location of the lane change schedule zone is at a second connecting location, or before the second connecting location, and to notify the driver of the plan to move the vehicle between lanes while the vehicle is traveling in the lane change schedule zone.

摘要： A system for generating a map is disclosed herein. The system may comprise a synthetic aperture radar (SAR) unit mountable to a terrestrial vehicle. The system may further comprise one or more computer processors operatively coupled to the SAR unit. The one or more computer processors may be individually or collectively programmed to: (i) while the terrestrial vehicle is in motion, use the SAR unit to (1) transmit a first set of signals to an environment external to the vehicle and (2) collect a second set of signals from the environment; and (ii) use at least the second set of signals to generate the map of the environment in memory.

摘要： The vehicle position estimation device includes a processor configured to estimate a vertical position of a vehicle based on an output of a vehicle state detection device, detect actual dividing lines at both left and right sides of the vehicle, compare a dividing line on a map at the vertical position of the vehicle and an actual dividing line and estimate a horizontal position of the vehicle, and determine a driving route of the vehicle. The processor is configured to calculate an amount of change of a horizontal position with respect to the driving route based on a map information for each of dividing lines of both left and right sides of the driving route in a predetermined range, and determine a dividing line on the map for comparison based on the amounts of change.

摘要： A map matching method, an apparatus and an electronic device related to the technical field of artificial intelligence such as high-precision map, autonomous driving, internet of vehicles, and smart cockpit, where a specific implementation is: when matching a high-precision map with a standard-precision map, firstly acquire road network data corresponding to the high-precision map and the standard-precision map to be matched; and construct a first graph network based on the road network data corresponding to the high-precision map, and construct a second graph network based on the road network data corresponding to the standard-precision map, then determine a matching result between the high-precision map and the standard-precision map based on the first graph network and the second graph network. By the method using the graph network, the matching of the high-precision map with the standard-precision map can be accurately realized, thereby effectively improving accuracy of the matching result.

摘要： A method for updating a map of the surrounding area wherein the map is used when controlling a transportation vehicle. The transportation vehicle attempts, when travelling along a carriageway, to detect a landmark recorded in the map of the surrounding area using sensors. In response to the transportation vehicle being unable to detect the landmark using its sensors, the transportation vehicle prepares a proposal for deletion which is sent to an external central computer. The proposal for deletion is examined in the external central computer and deletes the landmark from the map of the surrounding area in response to the proposal for deletion being verified. In the method, information regarding a visibility range for the landmark is entered in the map of the surrounding area specifying at what range the landmark is visible from a road permitting a more effective detection of landmarks.
