Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If vehicle propulsion control systems use optimized speed profile calculation, then energy consumption efficiency is improved, but calculation faults and errors occur due to system complexity
Solution Approach 1:
The system performs preliminary validation by determining an alternative target vehicle speed profile independently before comparing it with the optimized profile. This preliminary calculation serves as a sanity check to detect obvious errors in the optimization logic before they cause problematic vehicle operation.
Solution Approach 2:
The system implements feedback by comparing the alternative speed profile with the optimized speed profile and using this comparison to validate the optimization results. If discrepancies exceed a threshold, the system triggers a rationality check to prevent erroneous speed commands from being executed.
2Reliability
If the system determines alternative target vehicle speed profile independently for validation, then reliability of optimized profile is improved, but device complexity increases
Solution Approach 1:
The system introduces an intermediary validation layer that compares independently calculated alternative speed profiles with optimized profiles. This intermediary check acts as a mediator between the optimization algorithm and the vehicle control system, detecting errors without requiring complete redesign of the control architecture.
Solution Approach 2:
The system creates a simplified copy of the speed profile determination process that operates independently to generate alternative target speeds. This copy uses the same input data (route characteristics, vehicle parameters, historical data) but through a different computational path, enabling validation without duplicating the entire complex optimization system.
3Reliability
If the system performs rationality check by comparing speed profiles, then errors are prevented, but loss of time occurs in speed profile determination
Solution Approach 1:
The system performs partial validation by comparing only critical aspects of the alternative and optimized speed profiles rather than进行全面 verification. The rationality check focuses on detecting obvious errors and inconsistencies, performing sufficient validation to prevent harmful errors while avoiding exhaustive checking that would cause excessive time loss.
Solution Approach 2:
The system merges the alternative profile determination and validation processes into an integrated workflow that shares computational resources and data structures. By combining these functions, the system reduces redundant calculations and minimizes the total time required for both profile determination and validation.

AI summary
A method for providing a vehicle energy optimization rationality check includes identifying at least one route characteristic of a portion of a route being traversed by a vehicle, determining a vehicle energy consumption profile for the vehicle, determining a profile for a target vehicle speed based on the at least one route characteristic and the vehicle energy consumption profile, determining, based on at least the at least one route characteristic, an alternative target vehicle speed, and, in response to a difference between the target vehicle speed and the alternative vehicle speed being greater than a threshold, performing a default action.
