Abstract: This invention refers to a vehicle, comprising a drivable road detection part (32) is configured to receive map data from a storage device (33) and localization data from a localization device (22), and to create a first occupancy grid, each cell of which represents a first confidence of surrounding environment being drivable, based on the map data and/or localization data, an optical sensor based drivable road detection part (32c) configured to receive image data from an optical sensing device (20) and to create a second occupancy grid, each cell of which represents a second confidence of surrounding environment being drivable, based on the image data, and a fusing part (32d) configured to create a third occupancy grid, each cell of which represents a third confidence of surrounding environment being drivable, by fusing the first occupancy grid and the second occupancy grid.

Abstract: This invention refers to vehicle (10) comprising an inertial measurement unit (26) configured to output inertial related data, a wheel odometry unit (28) configured to output position related data, an electromagnetic sensor unit (20) configured to output first image data and second image data that is previous image data of the first image data, and a visual odometry part (31) configured to receive the inertial related data, the position related data, the first image data, and the second image data and to output an estimated pose of the vehicle (10) computed by associating a first feature point extracted from the first image data with a second feature point extracted from the second image data and evaluating the association of first feature point and second feature point based on the inertial related data from the inertial measurement unit (26) and the position related data from wheel odometry.

Abstract: A computer program product comprising computer-readable instructions that, when executed in a computer system including one or more computers, cause the computer system to receive a data set of a machine driven by a human or robot driver; condition said data set by grouping the data based on predefined or definable machine-control parameters; search the conditioned data for determining data imbalances within groups or sub-groups of the conditioned data; balance the data for which an imbalance was determined; and output the balanced data.
