Vehicle Track Planning Around Mandatory Deceleration Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for evaluating fuel efficiency in motor vehicles do not accurately account for route-specific data, particularly in urban areas with mandatory deceleration points, and cannot be used in global systems with vehicles of different specifications, limiting their effectiveness in reducing resource consumption and improving traffic safety.
Innovation Solution
A method that generates a resource-efficient track for motor vehicles by collecting and analyzing data associated with the vehicle, route, and subsequent vehicles, including mandatory deceleration points, to create an estimated track that considers infrastructure, traffic signs, obstacles, and other vehicles, allowing for optimized speed profiles and route adjustments to reduce energy consumption and improve safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing fuel efficiency evaluation methods are used, then general fuel consumption assessment is provided, but accuracy is reduced due to lack of route-specific data and mandatory deceleration points
Solution Approach 1:
The system pre-identifies mandatory deceleration points along the route before the vehicle reaches them, using route data to predict where speed reduction will be required. This allows the vehicle to optimize its speed profile in advance, maintaining higher speeds where possible while preparing for necessary decelerations, thereby improving fuel efficiency accuracy.
Solution Approach 2:
The route is divided into segments based on mandatory deceleration points and other route-specific features. Each segment is analyzed separately to determine optimal speed profiles and fuel consumption characteristics, allowing for more precise local化的 fuel efficiency evaluation rather than treating the entire route as a single unit.
2Measurement precision
If fuel efficiency evaluation is limited to similar vehicles and driving modes, then precision for specific vehicle types is improved, but adaptability to global systems with diverse vehicle specifications is reduced
Solution Approach 1:
The system adjusts fuel efficiency evaluation parameters based on vehicle-specific characteristics such as mass, aerodynamic properties, and propulsion system type. By dynamically modifying evaluation parameters to match the actual vehicle being assessed, the system maintains high precision across diverse vehicle types while remaining adaptable to global deployment.
Solution Approach 2:
The fuel efficiency evaluation system is designed to handle multiple vehicle types and driving modes within a single unified framework. The system can evaluate conventional vehicles, electric vehicles, and hybrid vehicles using the same route analysis methodology, making it universally applicable across diverse vehicle specifications while maintaining accuracy for each specific type.
3Reliability
If existing methods are used to identify operational problems, then vehicle maintenance issues are detected, but the ability to change driving mode for energy reduction is lost
Solution Approach 1:
The system continuously monitors actual fuel consumption against predicted consumption based on the optimized speed profile. When deviations are detected, it provides feedback to the driver suggesting driving mode adjustments or identifies potential operational problems. This dual feedback mechanism maintains vehicle reliability while enabling real-time driving mode optimization for energy reduction.
