Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If image-based detection is used to locate bumpy regions, then the detection process is simple, but the location accuracy is insufficient
Solution Approach 1:
The patent combines multiple detection methods (image-based detection and sensor-based detection) to locate bumpy regions. Image detection provides initial location information while sensor data (acceleration, attitude angles) provides precise measurement, merging the advantages of both approaches to achieve high accuracy without excessive complexity
Solution Approach 2:
The patent introduces an intermediary processing system that receives both image data and sensor data, processes them together, and generates the final bumpy region location. This intermediary layer integrates the simple image-based detection with precise sensor measurements to resolve the accuracy issue
2Measurement precision
If precise location detection is implemented using multiple sensors, then location accuracy improves, but device complexity increases
Solution Approach 1:
The patent makes the vehicle's existing sensors (accelerometers, attitude sensors) serve dual purposes: their primary function for vehicle control and a secondary function for bumpy region detection. This multi-functionality approach improves measurement precision without adding dedicated detection hardware, thus avoiding increased device complexity
Solution Approach 2:
The patent utilizes the vehicle's own operational data (driving state data including acceleration and attitude angles) to detect bumpy regions, rather than requiring separate dedicated detection systems. The vehicle essentially detects road conditions using its own response to those conditions, achieving precise detection without additional device complexity

AI summary
The present disclosure provides a method and apparatus for detecting a bumpy region of a road surface, an electronic device, a storage medium, a computer program product, and a vehicle, and relates to the field of computer technology. The method includes: acquiring driving state data of a vehicle and an orientation of the vehicle; determining, according to the driving state data, whether the vehicle passes through the bumpy region of the road surface; and in a case where the vehicle passes through the bumpy region of the road surface, determining a location of the bumpy region of the road surface according to the driving state data and the orientation of the vehicle. According to the present disclosure, the bumpy region of the road surface can be accurately located, thereby effectively reminding other vehicles to take measures in time and reminding road maintenance personnel to carry out road maintenance in time.
