Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in navigating tight spaces and avoiding obstacles due to difficulties in judging the sufficiency of passing intervals and recognizing the positions of objects, leading to potential collisions or unsafe maneuvers in passing-through and passing-each-other scenarios.
Innovation Solution
A driving assistance device that acquires a surrounding area map, determines travelability, generates a guide to assist steering, and updates reference position information based on the deviation between the guide and the actual trajectory, ensuring safe passage by adjusting the relative positions of obstacles and the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers manually judge passing intervals and navigate tight spaces, then they maintain full control of the vehicle, but they face difficulties in accurately judging sufficiency of passing intervals and recognizing object positions, leading to potential collisions or unsafe maneuvers
Solution Approach 1:
The driving assistance device serves as an intermediary between the driver and the complex task of judging passing intervals. The device acquires surrounding area maps, determines travelability, generates guides, and adjusts reference position information to assist the driver in making accurate judgments about whether it is safe to pass through tight spaces, thereby improving reliability without unduly complicating the driving operation
Solution Approach 2:
The patent replaces the manual mechanical judgment process with an automated information processing system. The driving assistance device uses sensors and processors to acquire surrounding area maps, determine travelability, and generate guidance information, substituting the driver's manual judgment capability with an automated system that can accurately assess passing intervals and object positions
2Measurement precision
If the driving assistance device adjusts reference position information based on deviation between guide and actual trajectory, then the accuracy of future guidance is improved, but the complexity of the system increases
Solution Approach 1:
The driving assistance device implements a feedback mechanism where it acquires the actual trajectory of the vehicle, compares it with the generated guide, determines the degree of deviation, and uses this information to update reference position information. This feedback loop continuously improves the accuracy of future guidance while maintaining a manageable level of system complexity through iterative refinement
Solution Approach 2:
The device performs preliminary adjustments to reference position information based on accumulated deviation data from previous guidance operations. By learning from past trajectory deviations and pre-adjusting reference positions, the system improves future guidance accuracy without requiring complex real-time calculations, thereby managing system complexity
