A method for operating a vehicle includes carrying out a lane-keeping control of the vehicle along a course of a lane travelled in by the vehicle. When lane markings are detected, the course of the lane is determined on a basis of detected lane markings. When lane markings are not detected, the course of the lane is determined in a mapped-based manner on a basis of data from a digital map where a rough localization of the vehicle in the digital map and a fine localization of the vehicle in the digital map is performed.

The disclosure relates to a method for generating a reference trajectory within a lane for a vehicle. The method comprises receiving at least one vehicle current state parameter describing a current state of the vehicle (S11). The current state of the vehicle comprises at least a current position of the vehicle. Furthermore, a destination parameter describing a destination to be reached by the vehicle (S12), and at least one route parameter describing a route for reaching the destination (S13) are received. Moreover, the method comprises estimating a power loss being caused when traveling from the current position of the vehicle to the destination (S14). The reference trajectory within the lane is determined such that it minimizes the power loss and leads to the destination (S15). Additionally, a method for operating a vehicle is presented. According to this method, a reference trajectory is generated in accordance with the above method (S21) and at least one control signal is provided for controlling a motion of the vehicle along the reference trajectory (S22). Furthermore, a data processing apparatus, a vehicle and a computer-readable medium are presented.

An entry point and an exit point are specified in a non-lane section. A lane definition line is searched to be continuous in a longitudinal direction of the road from the entry point to the exit point. A virtual lane marking line is generated to connect between the lane marking line on an entry side and the lane marking line on an exit side, based on the lane definition line detected as a search result. A travelling track is generated as a trajectory on which a vehicle is scheduled to travel, based on the virtual lane marking line.

A driving assist method minimizes an incidence of lane changing within a circulatory roadway. In this driving assist method, a recognition assessment processor assesses the travel of a host vehicle, calculates a travel route over which the host vehicle is to travel, and executes a driving assist control based on the travel route. The recognition assessment processor further assesses whether the host vehicle has arrived at a roundabout having a circulatory roadway to which three or more radial roadways are connected. When an assessment has been made that the host vehicle has arrived at the roundabout, a position of a host vehicle entrance and a position of a host vehicle exit are specified. Furthermore, an entrance position is set based on a positional relationship between the host vehicle entrance and the host vehicle exit.

A processor of a route provision apparatus according to an embodiment of the present invention is characterized in outputting map information received from a server, on a rollable display provided in a vehicle, determining a change in the size of a display area of the rollable display, and requesting the server for map information to be displayed on the changed display area, on the basis of the changed size of the display area, and receiving the map information.

An electronic device attachable to a vehicle, according to various embodiments of the present invention, comprises: a communication interface; a memory for storing instructions; and at least one processor connected to the communication interface and the memory, wherein the at least one processor can be configured so as to execute the stored instructions in order to: acquire, from another device embedded in the vehicle, information on a plurality of objects located within a designated distance from the vehicle; identify, among the plurality of objects, a designated object located within a designated distance from the vehicle; generate configuration information of at least one piece of content to be displayed through a head-up display (HUD), on the basis of a state of the designated object; and display, through the HUD, content for guiding the operation of the vehicle, on the basis of the generated configuration information.

A display control device includes a display that is configured to display information, a detector that is configured to detect a partition line for partitioning a lane on a road on which a vehicle is present, and a display controller that is configured to cause the display to display the partition line detected by the detector variably, and the display controller is configured to change a length of the partition line which is displayed by the display on the basis of a detection distance of the detector.

Provided are a method, a device, and a computer program for providing a driving guide by using vehicle position information and signal light information.

The method may comprise the steps of: collecting image data obtained by photographing a space where a vehicle is currently driving; determining a current driving lane of the vehicle by using the image data and vehicle position information; and providing a driving guide for the vehicle by using the current driving lane of the vehicle.

A method for constructing a lane-level navigation map is provided. The method may include: determining a change position of a lane in a road-level electronic map; extracting lane information of the change position of the lane, the lane information including a lane connectivity relationship; and storing the lane information in the road-level electronic map to obtain the lane-level navigation map.

A method is provided for a navigation device to display maneuvering instructions along a route, involving: displaying a digital map in a perspective manner on a display unit of the navigation device; according to the distance of the navigation device from the location of the maneuver, i.e. the location where a maneuver is to be carried out as per the route: displaying first maneuvering instructions for the maneuver when the navigation device is farther from the location of the maneuver than a predefined distance; displaying second maneuvering instructions instead of the first maneuvering instructions for the maneuver when the navigation device is closer to the location of the maneuver than the predefined distance; the first and second maneuvering instructions being displayed in such a way as to cover up a portion of the displayed digital map; displaying a graphic link between the location of the maneuver on the digital map and the first or second maneuvering instructions.
