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 deceleration points are not considered
Solution Approach 1:
The evaluation system segments the route into portions with mandatory deceleration points and portions without, allowing separate analysis and evaluation for each segment. This enables precise calculation of energy consumption by considering the specific characteristics of deceleration portions while maintaining manageable data processing complexity through structured segmentation.
Solution Approach 2:
The system pre-identifies mandatory deceleration points and classifies route portions before conducting fuel efficiency evaluation. By preparing route classification data in advance, the system eliminates the need for complex real-time analysis during evaluation, thereby improving accuracy without proportionally increasing processing complexity.
2Adaptability or versatility
If existing evaluation methods are used, then fuel efficiency can be assessed, but the method cannot be applied globally to vehicles with different specifications and routes
Solution Approach 1:
The evaluation system is designed with universal applicability by accepting various vehicle specification data and route characteristic data as inputs. The method can process data from different vehicle types and diverse route conditions through a unified evaluation framework, enabling global deployment while maintaining precision through vehicle-specific and route-specific parameter integration.
Solution Approach 2:
The system adapts to different vehicles and routes by dynamically adjusting evaluation parameters based on vehicle specifications and route characteristics. By modifying parameters such as vehicle mass, aerodynamic properties, and route geometry factors, the system maintains measurement precision across diverse applications without requiring separate evaluation methods for each vehicle-route combination.
3Use of energy by moving object
If existing methods are used, then operational problems affecting fuel consumption can be identified, but energy consumption cannot be reduced by adjusting driving mode for mandatory deceleration points
Solution Approach 1:
The system dynamically generates speed profiles that adapt to mandatory deceleration points by optimizing acceleration and deceleration phases. The track generation process continuously adjusts speed recommendations based on the distance to upcoming deceleration points, enabling energy-efficient driving mode adjustments without requiring overly complex control systems.
Solution Approach 2:
The evaluation system provides feedback on energy consumption patterns related to mandatory deceleration points, enabling drivers to adjust their driving behavior. By presenting information about optimal speed profiles and actual energy consumption, the system facilitates energy reduction through informed driving decisions while maintaining manageable system complexity.
