Traffic Rules Engine
Law-Aware Intelligence for Automated Driving
Beyond collision avoidance — towards legal compliance
The Traffic Rules Engine empowers autonomous and ADAS Level 3+ vehicles with a continuously updated, machine-readable understanding of global traffic laws. It interfaces with perception and motion planning systems to provide transparent legal awareness — ensuring every driving decision is made with full knowledge of the applicable rules.
Running on-vehicle in real time, it utilizes perception data to determine the legality of the vehicle’s current state and to assess the legality of maneuvers to be initiated. This awareness supports and enhances planning and control systems — without demanding control or enforcing decisions.
Always Compliant: OTA updates reflect the latest global traffic laws.
Law Logic: Complex legal texts translated into machine-readable rules.
Seamless Integration: Built for ADAS ECUs with real-time interfaces.
Designed for Trust. Built for Integration.
Traffic Rules Engine analyzes the vehicle’s perceived situation based on data from sensors and maps.
Using its internal knowledge of applicable traffic regulations, it assists the Motion Planning System by providing well-founded legal insights and guidance.
Through this analysis, TRE informs the system about the vehicle’s current legal status and identifies the maneuvers legally permissible in the given context.
