Embodiment Construction

[0038] The present invention proposes an improved method for monitoring and regulating the performance and thus safety of a fusion system 1 of an autonomous road vehicle 2 .

[0039] This can be provided by a method for monitoring and regulating the performance of a fusion system 1 of an autonomous road vehicle 2 equipped with an autonomous driving system 3 comprising a positioning system 4 (e.g. a satellite positioning system 4 such as GPS) and a A plurality of sensors 5 monitor the internal state of the autonomous road vehicle 2 and the surrounding environment. Examples of sensors 5 for monitoring the surrounding environment include radar, lidar and camera based sensors 5 .

[0040] Fusion system 1 of autonomous road vehicle 2 as used here indicates different functions and algorithms that use sensor data to estimate information required for autonomous driving control of autonomous road vehicle 2 .

[0041] The positioning function of the fusion system 1 is provided by fusin...

Abstract

Method and apparatus for monitoring and regulating the performance of a fusion system (1) of an autonomous road vehicle (2). The drivable area (6) is determined by combining positioning functions and high-density map (7) data. Determining information about surrounding objects (8), including determining localization and classification of surrounding objects, estimating their physical property states, and specifying their extended descriptions. Condensation of information about the drivable area (6) and surrounding objects into an observation area (9) monitored with a predetermined degree of certainty by sensors (5) of the environment awareness function and prioritized objects represented by classification, state estimates and extended descriptions . Causes the fusion system to monitor itself retroactively by evaluating its current determination relative to its previous determination of drivable area (6), priority target (8) and viewing area, and if the previous determination differs from the current determination by more than a predetermined amount, The fusion system is then adapted to compensate for this difference.

Description
