Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to accurately specify the absolute position of leaning vehicles, such as motorcycles, which is crucial for effective driving support systems.
Innovation Solution
An information processing system that utilizes a radar to acquire surrounding environment information, creates or updates a map based on this data, and specifies the absolute position of the vehicle using this information, optionally considering reliability factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional positioning methods are used for leaning vehicles, then the system complexity is reduced, but the measurement precision of absolute position cannot be ensured
Solution Approach 1:
The patent combines radar-based surrounding environment detection with map data to specify the absolute position of the leaning vehicle. The acquiring section obtains surrounding environment information from the radar, and the specifying section integrates this with map data to determine the absolute position, thereby achieving high precision without requiring complex dedicated positioning hardware.
Solution Approach 2:
The patent introduces an intermediary approach by using surrounding environment information as a mediator between the radar data and the absolute position specification. This intermediary layer allows the system to leverage existing radar functionality while achieving precise positioning through environmental context analysis.
2Reliability
If driving support systems require accurate absolute position information, then the reliability of driving support functions is improved, but the difficulty of detecting and measuring position accurately increases
Solution Approach 1:
The system continuously acquires surrounding environment information from the radar and uses it to specify and update the absolute position. This feedback loop ensures that the position information remains accurate and reliable for driving support functions, as the system adapts to changing environmental conditions in real-time.
Solution Approach 2:
The patent makes the radar system serve multiple functions: it not only detects surrounding obstacles for safety but also provides the data needed for absolute position specification. This multi-functionality reduces the need for separate positioning systems while maintaining high reliability for driving support operations.
