Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing fuel efficiency evaluation methods are used, then fuel efficiency can be evaluated based on driving data and vehicle status, but the accuracy is reduced because route-specific data and mandatory stop points are not considered
Solution Approach 1:
The system pre-collects and stores route-specific data including mandatory stop points, geometry, and environmental conditions before fuel efficiency evaluation. This preliminary preparation allows the evaluation algorithm to access pre-processed route information, improving accuracy without increasing real-time computational complexity
Solution Approach 2:
The evaluation process is segmented into distinct modules: route data collection, mandatory stop point identification, speed profile analysis, and energy consumption calculation. Each module handles specific aspects independently, improving measurement precision while organizing complexity into manageable segments
2Adaptability or versatility
If existing evaluation methods are used, then fuel efficiency can be assessed, but the method cannot be applied to global systems with vehicles of different specifications
Solution Approach 1:
The system adjusts evaluation parameters based on vehicle specifications, route characteristics, and environmental conditions. By dynamically changing parameters such as speed profiles, acceleration rates, and stop durations to match specific vehicle types and route requirements, the method achieves both versatility across different vehicle fleets and precision in fuel consumption estimation
Solution Approach 2:
The evaluation system is designed with universal applicability through standardized data structures and flexible parameter configurations that can accommodate different vehicle types, route categories, and operational conditions. The core algorithm remains consistent while adapting to various inputs, enabling deployment in global systems with diverse vehicle specifications
3Ease of operation
If existing methods are used, then operational problems can be identified, but energy-efficient tracks with mandatory stop points cannot be generated
Solution Approach 1:
The system pre-identifies mandatory stop points along the route and pre-calculates optimal speed profiles that account for these stops. By preparing this information in advance, the system can generate energy-efficient tracks that minimize travel time before mandatory stops without requiring real-time adjustments, improving ease of operation while reducing time loss
4Use of energy by moving object
If speed profiles are optimized for energy efficiency, then energy consumption is reduced, but the system becomes more complex
Solution Approach 1:
The system uses the vehicle's own operational data, such as actual speed, acceleration, and energy consumption patterns, to automatically generate and refine speed profiles. This self-service approach allows the system to optimize energy efficiency using existing vehicle characteristics without requiring complex external control mechanisms, reducing the perceived device complexity while achieving energy savings

AI summary
A method for generating an energy-efficient track for the vehicle in operation comprises: obtaining data associated with the first motor vehicle: data associated with the portion of the route to be passed by the first motor vehicle, and data associated with the second motor vehicle: generating a track for the first motor vehicle, that stops for a given period of time: generating an estimated track for the second motor vehicle based on the track generated for the first motor vehicle: generating a speed profile of the first motor vehicle on the passed portion of the route, and evaluating energy efficiency of the first motor vehicle on the passed portion of the route on the basis of the first motor vehicle stopping. Effect: reducing energy consumption by the motor vehicle moving along a portion of the route containing a mandatory stop point where the motor vehicle stops for a given period of time.
