Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional testing methods are used for ramp driving performance, then testing can be performed, but the testing is not cost-effective and cannot accurately detect driving performance in ramp scenarios
Solution Approach 1:
The patent uses GPS track information as a virtual copy of the vehicle's actual movement to analyze and detect ramp driving performance. Instead of complex physical testing apparatus, the system creates a digital representation of the vehicle's trajectory through GPS data points, allowing for cost-effective analysis of stopping accuracy, sliding detection, and overall ramp performance without requiring specialized physical testing equipment
Solution Approach 2:
The patent replaces complex mechanical testing systems with an information-based detection system. By substituting physical measurement devices with GPS-based positional tracking and computational analysis, the system achieves reliable detection of ramp driving performance through software processing of location data rather than through complex mechanical sensing and measurement apparatus
2Reliability
If no ramp testing method is implemented, then device complexity is reduced, but driving safety cannot be ensured due to inability to detect performance in ramp scenarios
Solution Approach 1:
The patent implements a feedback mechanism by continuously monitoring GPS track information during ramp operations and comparing actual vehicle positions against expected trajectories. The system provides real-time feedback on stopping accuracy by calculating the distance between actual and target stopping positions, and detects sliding accidents by analyzing unexpected movements in the GPS data, enabling continuous validation of ramp driving performance
Solution Approach 2:
The patent introduces GPS track information as an intermediary element that mediates between the vehicle's physical movement and the detection system. Rather than directly measuring physical parameters like force or acceleration, the system uses GPS positional data as an intermediate representation that can be easily processed and analyzed to infer driving performance and detect anomalies such as sliding accidents
3Measurement precision
If GPS track information analysis is used to detect sliding accidents, then detection accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent applies partial action by focusing GPS data analysis specifically on key indicators of sliding accidents rather than processing all possible vehicle parameters. The system monitors only the critical aspects of GPS track information that indicate abnormal movements or deviations from expected stopping behavior, achieving accurate sliding detection while minimizing unnecessary data processing complexity

AI summary
A method and an apparatus for testing a ramp driving performance, and a storage medium, where the method includes: controlling, according to a preset traveling track, an automatic driving vehicle to perform a stopping operation when the automatic driving vehicle is traveling on a ramp to a reference position; obtaining relative position information between an actual stopping position of the automatic driving vehicle and a reference object disposed at the reference position; and determining, according to the relative position information, whether the automatic driving vehicle is accurately stopped on the ramp. The driving performance of the automatic driving vehicle in a special scenario, such as ramp stopping, can be accurately detected, thereby ensuring a driving safety of the automatic driving vehicle in the ramp stopping scenario.
