Abstract: A brake signal transmitter (10) includes a housing (11) and a liquid drainage system (20). The liquid drainage system (20) includes an opening in the housing (11) and a cover (30) that extends over or along the opening. The cover (30) includes at least one aperture that allows a liquid to be drained through the cover (30). The opening (21) of the housing (11) is arranged on a downward side of the housing (11) relative to a gravitational force the transmitter is mounted horizontally. The cover (30) may be a cap having a filter inserted therein. The filter may define a tortuous path to block ingress of water or debris into the housing. The cover may include resilient fingers that snap fit into a socket of the housing.

Abstract: Disclosed herein is a technique for generating map change data relative to the current map data and providing these changes to an autonomous vehicle for use in updating the current map data that it retrieves or obtains from a local storage. The technique processes observation data received from other vehicles to determine the map change data.

Abstract: Disclosed herein is a technique for processing map change data in a map client that uses the map changes to apply changes and updates to current map data. The map client provides the updated map data to other components in an autonomous vehicle. The map change data describes the processing in the map client to obtain updated map data from the map data.

Abstract: Methods and systems for improved positioning accuracy relative to a digital map are disclosed, and which are preferably used for highly and fully automated driving applications, and which may use localisation reference data associated with a digital map. A vehicle localization is obtained by comparing real time depth map acquired by a sensor associated to the vehicle to a depth map associated to a digital map. The depth maps are indicative of an environment around the vehicle. Longitudinal and lateral offsets of the vehicle with respect to the digital map are determined. The invention further extends to methods and systems for the generation of localisation reference data associated with a digital map.

Abstract: A method of determining a longitudinal position of a vehicle (100) relative to a digital map is disclosed in which real time scan data (200, 202) is determined by scanning a lateral environment around the vehicle using at least one range-finder sensor, said real time scan data comprising one or more depth maps, each depth map representing the measured lateral distance to surfaces in the lateral environment for a plurality of longitudinal positions and elevations. Localization reference data associated with the digital map for a deemed current longitudinal position of the vehicle (100) in relation to the digital map is retrieved, and compared to the real time scan data (200, 202) by calculating a cross-correlation to determine a longitudinal offset. The deemed current longitudinal position is adjusted based on said longitudinal offset to determine the longitudinal position of the vehicle (100) relative to the digital map.

Abstract: A navigation system for use in a vehicle (402). The system includes an absolute position sensor, such as GPS, in addition to one or more additional sensors, such as a camera, laser scanner, or radar. The system further comprises a digital map or database that includes records for at least some of the vehicle's surrounding objects (400). These records can include relative positional attributes with respect to a reference axis (404). As the vehicle (402) moves, sensors sense the presence of at least some of these objects (400), and measure the vehicle's relative position to those objects. This information is used to determine the vehicle's instantaneous lateral offset (428) relative to the reference axis (404), and support features such as enhanced driving directions, collision avoidance, or automatic assisted driving. The system also allows new objects (408, 414) to be attributed using relative positioning, and thereby factored into the enhanced navigation features.

Abstract: A method of generating a geodetic reference database product is disclosed The method comprises acquiring mobile mapping data captured by means of digital cameras, range sensors and position determination means including GPS and IMU mounted to a vehicle driving across the earth surface, the mobile mapping data comprising simultaneously captured image data, range data and associated position data in a geographic coordinate system. Linear stationary earth surface features are derived from the mobile mapping data by processing the image data, range data and associated position data. 3D-models are generated for the linear stationary earth surface features in the geographic coordinate system from the image data, range data and associated position data and stored in a database to obtain the geodetic reference database product. A 3D-model could include an image representing the colors of the surface of the 3D model or a set of smaller images representing photo-identifiable objects along the model.
