Abstract: To check an electrohydraulic power vehicle brake system of a passenger car traveling autonomously on public roads for air in the brake fluid, the method provides for a consecutive generation of a brake pressure using a first power brake-pressure generator and a redundant, second power brake-pressure generator. The brake pressure is intermittently lowered to ambient pressure. In the method, a comparison of the brake fluid volumes required for generating the brake pressure is provided. If the brake fluid volume required for generating the brake pressure using the second power brake-pressure generator is greater, then the presence of air in a brake fluid of the vehicle brake system is inferred.

Abstract: Systems and methods for constructing and managing a unique road sign knowledge graph across various countries and regions is disclosed. The system utilizes machine learning methods to assist humans when comparing a new sign template with a plurality of stored sign templates to reduce or eliminate redundancy in the road sign knowledge graph. Such a machine learning method and system is also used in providing visual attributes of road signs such as sign shapes, colors, symbols, and the like. If the machine learning determines that the input road sign template is not found in the road sign knowledge graph, the input sign template can be added to the road sign knowledge graph. The road sign knowledge graph can be maintained to add signs templates that are not already in the knowledge graph but are found in real-world by integrating human annotator's feedback during ground truth generation for machine learning.
