A map information system includes a map database including map information; and a driving assist level determination device. The map information is associated with an evaluation value indicating a certainty of the map information for each location in an absolute coordinate system. Information indicating that the intervention operation is performed is included in driving environment information indicating a driving environment of a vehicle. The driving assist level determination device is configured to acquire, based on the driving environment information, intervention operation information indicating an intervention operation location where the intervention operation is performed, acquire, based on the map information, the evaluation value for each point or section in a target range, and determine, based on the evaluation value and the intervention operation location, an allowable level for each point or section within the target range.

In an embodiment, a method comprises detecting, at a processor of an autonomous vehicle, a discrepancy between a map and a property sensed by at least one sensor onboard the autonomous vehicle, the property being associated with an external environment of the autonomous vehicle. In response to detecting the discrepancy, and based on the discrepancy, an annotation for the map is generated via the processor. A signal representing the annotation is caused to be transmit to a compute device that is remote from the autonomous vehicle. A signal representing a map update is received from the compute device that is remote form the autonomous vehicle. The map update is generated based on the annotation, the map update (1) including replacement information for a region of the map associated with the annotation, and (2) not including replacement information for a remainder of the map.

Disclosed herein are methods for decoding path data. The methods may comprise providing a navigation database for storing topological information of a road network. The navigation database comprises a plurality of road links, and a plurality of link nodes, each link node defining a topological connection between two or more of the road links. The methods may further comprise receiving path data indicative of a path within the road network, wherein the path data comprises a start identifier, a link count, and at least one exit number. The methods may further comprise selecting, from the navigation database, one road link of the plurality of the road links as a start road link of the path based the start identifier. Moreover, the methods may comprise iteratively expanding the path with selected road links until the link count is equal to the number of road links of the path.

Provided herein is a method of generating and communicating map version agnostic road link identifiers. Methods may include: receiving an indication of a new road link being joined to an existing road link along a length of the existing road link, where the existing road link extends between a first node and a second node, where the existing road link has a first road link identifier, and where a new node is formed where the new road link joins the existing road link; generating a first new identifier for a segment of the existing road link between the first node and the new node; generating a second new identifier for a segment of the existing road link between the new node and the second node, where the second new identifier is set equal to an XOR function of the first road link identifier and the first new identifier.

An information processing device includes a control unit that executes: acquiring a first route based on a communication speed; and creating a first plan for a first vehicle, the first plan being a plan about execution of download of first data during traveling along the first route. The control unit acquires the first route between two predetermined spots, based on a first map indicating a distribution of a communication speed of a first communication carrier that is employed in the first vehicle. The control unit acquires a route for which it is predicted that a time spent on the download of the first data is shortest.

A method for providing data for a driver assistance system of a motor vehicle includes communicating position data concerning a position of the motor vehicle to the driver assistance system, requesting additional information from a server if the driver assistance system requires additional information with respect to the position data, and communicating, in response to the requesting, the additional information from the server to the driver assistance system.

A mobile apparatus receives a route response including information identifying a starting location and a target location of a route and an encoding data structure encoding the route. The encoding data structure is a probabilistic data structure configured to not provide false negatives. The mobile apparatus uses the information identifying the starting and target locations to identify a decoded origin traversable map element (TME) and a decoded target TME of the mobile version of the digital map for the route; accesses map information for determining a cost value for TMEs of the digital map, wherein a TME that satisfies the encoding data structure is assigned a minimal cost value; determines a decoded route from the decoded starting TME to the decoded target TME based on the cost value assigned to the TMEs using a cost minimization route determination algorithm; and performs at least one navigation function using the decoded route.

The use of predefined (pre-built) graphical representations of roads for autonomous driving of vehicles and display of route planning.

The present invention relates to a method of generating and using a new data set for a novel technique of autonomous vehicle driving and route planning display using a predefined graphic representation/definition/illustration of the vehicle surroundings, in combination with the actual view sighted and captured by video cameras from the vehicle (for example, a dashboard camera). This method is primarily based on the use of the predefined graphic representation of the actual visual scene that is sighted from a host vehicle on roads at known GPS locations.

The main feature of this disclosure is the use of a predefined and simplified graphic illustration of the actual view experienced from vehicles on roads. This data is prepared in advance, stored in a cloud-based facility, and can be accessed by any vehicle.

The method comprises at least one video camera mounted in the vehicle, a module for accessing the predefined graphic visualization of the road and its surroundings, a module for defining the exact position and direction of the host vehicle on the predefined graphic view of the road, based on the use of GPS in combination with the identification of the surrounding characteristics of the road, a module continuously aligning the graphic view with the real view filmed by the video camera and for displaying the graphic visualization of the real view filmed by a forward facing camera.

The present invention relates to a new method for generating data that can be used in the vehicle's autopilot and for displaying route planning.

Numerous variations and modifications of the invention may be considered other than those described herein without departing from the spirit and scope of the present invention. This invention should not be limited by the specific details described herein.

The above measurement device acquires output data from a sensor unit for detecting surrounding feature, and extracts, from the output data, data corresponding to detection result in a predetermined range in a predetermined positional relation with an own position. The predetermined range is determined in accordance with accuracy of the own position. Then, the measurement device executes predetermined processing based on the extracted data.

Provided is a system for generation of a customized digital map. The system includes an application server that collects one or more reference transportation routes and regulations associated with a geographical area and one or more current transportation routes and activities being implemented in the geographical area. The application server detects one or more conflicts among a digital map of the geographical area, the one or more reference transportation routes and regulations, and the one or more current transportation routes and activities and executes a conflict resolution routine that resolves the one or more conflicts. The application server further generates conflict resolved data based on an output of the conflict resolution routine and updates the digital map of the geographical area to reflect the conflict resolved data based on presence of at least one difference between the digital map and the conflict resolved data.
