Navigation System Route Optimization Using Contextual Fuel Factors

The patent segments the route evaluation process into distinct modules: a route generation module that creates multiple candidate routes, a context determination module that identifies user-specific conditions, a fuel usage factor calculation module that computes fuel consumption for each route, and a route selection module that chooses the optimal route. This segmentation allows the system to handle complexity through organized, independent functional blocks rather than a monolithic structure.

The system performs preliminary determination of context factors (such as vehicle type, driver behavior patterns, and environmental conditions) before route calculation begins. By pre-establishing these contextual parameters, the system avoids re-evaluating them for each route option, thereby reducing computational complexity while maintaining comprehensive route optimization capability.

The system pre-determines context factors such as vehicle characteristics, driver behavior patterns, and environmental conditions before initiating route calculations. By having these parameters ready in advance, the system eliminates the need to recalculate them for each route option, significantly reducing computation time while preserving the accuracy benefits of considering multiple factors.

The patent transforms complex fuel consumption calculations into a simplified mathematical model that uses standardized parameters (base fuel consumption rate, route-specific modifiers, and context-based adjustment factors). This parameterization allows the system to maintain high estimation accuracy while achieving computationally efficient calculations that can be performed rapidly.

The system applies context-based filtering selectively to different route options based on their specific characteristics. Rather than applying a uniform elimination criterion to all routes, the system evaluates each route against the determined context factors and eliminates only those that are demonstrably irrelevant to the user's specific situation. This preserves adaptability by maintaining routes that may be suboptimal in general but suitable for particular user needs.

The route elimination process is dynamic and adaptive, adjusting the strictness of filtering based on the determined context. When context indicates the user prioritizes certain factors (such as avoiding tolls or preferring scenic routes), the system dynamically adjusts which routes are eliminated and which are retained, ensuring that efficiency gains do not come at the cost of user-specific adaptability.
